REPORT ON SOME MEXICAN HYMENOPTERA, PRIN- 
CIPALLY FROM LOWER CALIFORNIA. 


BY WILLIAM Jj. FOX. 


The collections on which this paper is based were 
made principally throughout Lower California. I say 
throughout, as collections were made, beginning at San 
Quintin in the north, to San José del Cabo in the ex- 
treme south, as well as in divers localities in the east and 
west, such as Magdalena Island and San Juan. The 
collection as a whole, though not very extensive, is, in 
my opinion, one of the most important that has ever been 
brought from that region, as not only do the specimens 
bear the precise locality in which they were collected, 
but have the date of capture as well, which, as every en- 
tomologist must admit, is not only interesting but import- 
ant. To Mr. Gustav Eisen, of the California Academy 
of Sciences, my thanks are due for the opportunity of 
examining these collections, and who collected those spec- 
imens from SanJosé del Cabo and Hermosillo, Sonora. 
The remainder were collected by Mr. Chas. D. Haines, 
who deserves credit for the neat and careful way in which 
he has prepared his specimens. My thanks are also due 
Mr. Wm. H. Ashmead and Mr. Theo. Pergande, of 


2p S=R., Vou. IV. September 14, 1893.

Washington, D. C., for determining the Parasitica and 
Formicidae. (The latter will be found in a separate paper 
by Mr. Pergande.) I might state that several species of 
the smaller bees, which are evidently new, I have re- 
frained from describing, as a lack of Mexican material 
renders their identification ambiguous.

species, although it agrees fairly well with the description, 
except that the second segment is usually black. It is 
probably a variety.”’

bamjelee Cals ~CAlaznes). uApiil. 

CHRYSIS SELENIA Costa. Six specimens. San José del 
Cabo (£#zsew) and Comondu, L. Cal. (/faznes). March. 

PARNOPES CHRYSOPRASINA Sm. 

Although this species was described from North Caro- 
lina and to my knowledge has not been recorded from 
any other locality, I feel compelled to refer a specimen 
from San Borgia, L. Cal. (/famnes) May, to it, as the 
specimen fits the description perfectly. It seems to me 
that Smith has probably given an erroneous locality for 
this species. Should this specimen prove not to be 
chrysoprasina, then it is a new species, as it is distinct 
from both Kdwardsi and fulvicornis. 


MUTILLIDA. 


SPH £ROPHTHALMA oORCUuS Cress. Five females. Santa 
Maria, L. Cal. (Afaznes) May; Hermosillo, Sonora (£7- 
sen) April. ‘The pubescence on abdomen of this species 
varies from fulvous to bright carmine.

SPHZROPHTHALMA GLORIOSA Sauss. San Esteban, 
April, and San Borgia, May (//azves), San José del Cabo 
(Eisen). This species seems to have been overlooked 
by previous authors as it is neither in Blake’s Monograph 
of the Mutillide, nor in Cresson’s ‘‘ Catalogue.’’ It is 


HYMENOPTERA FROM LOWER CALIFORNIA. 5 


related to Sackenz?, from which it will be at once dis- 
tinguished by the reddish body-color. 

PHOTOPSIS CASTANEUS Cress. El Paraiso, L. Cal. 
(Haines) May. 

PHOTOPSIS NEBULOSUS BI. Five specimens. El] Pa- 
raiso, May, and Calmalli Mines, L. Cal., April (AZaznes).

Cal. (Zzsen). One specimen. 


PHOTOPSIS INCOoNsPICUUS Bl. Margarita Island, L. 
Cal. (Haines). March. One specimen.

du (March) and Calmalli Mines, L. Cal. (Haznes). 


Puotopsis Nokomis Bl. Two specimens. San Jose 
delGabpo, L.Cal--( Azer). Lhe color of the abdomen 
in this species varies from dark ‘* honey-yellow ”’ to black. 

PHOTOPSIS NIGRIVENTRIS N. sp. 

6 .—Head scarcely as wide as the thorax, hind angles 
rounded; vertex with strong, sparse punctures, those on 
the front closer and not quite so strong; ocelli large and 
prominent; scape punctured; mandibles strongly punc- 
tured at base, which is produced outwardly into a strong 
angular lamina or tooth. Clypeus strongly depressed: 
thorax with coarse punctures, those on the prothorax, 
metapleure: and scutellum more or less confluent and 
those on dorsulum sparsest; the metathorax covered with 
large fovee or pits, the base with a strong ridge medially, 
extending about one-fourth the length of the metathorax, 
on each side of this ridge there is a somewhat oblique and 
shorter ridge; legs not at all spinose; abdomen fusiform, 
the first segment above with strong, separated punctures, 
beneath on same segment the punctures are stronger and 
confluent, dorsalsegments 2-6 with fine punctures, which 


6 CALIFORNIA ACADEMY OF SCIENCES. 


are sparsest on second segment, ventrally these seg- 
ments are more strongly punctured, particularly on the 
second segment; wings subhyaline, stigma brown, nerv- 
ures yellowish, with two submarginal cells (there is, 
however, faint traces of a third); head and thorax of a 
ferruginous brown, the antennz, palpi, tegule and legs 
honey-yellow; abdomen, except first segment, which is 
colored like thorax, and the ocellar region, black; man- 
dibles with long golden hair, the rest of the insect with 
long, rather dense, pale pubescence; segments of ab- 
domen at apex with a fringe of short, white pubescence ; 
the last dorsal segment with brown pubescence. Length, 
16-18 mm. 

Two specimens. San José del Cabo, L. Cal. (4zsez). 


PuHotopsis BLAKEII n. sp. 

6 .—Head scarcely as wide as the thorax, hind angles 
rounded; vertex with strong, sparse punctures, those on 
the front not much closer nor feebler: ocelli large and 
prominent, the hind pair situated in strong pits; scape 
punctured; outer margin of mandibles, with exception of 
a slight emargination in middle, entire; thorax with coarse 
punctures, those on prothorax and mesopleure more or 
less confluent; scutellum with strong and not confluent 
punctures; metathorax covered with large pits or fovee, 
the base with a strong ridge medially, which extends over 
one-third the length of the metathorax, on each side of 
this ridge there is a much shorter, oblique ridge; legs not 
at all spinose; abdomen fusiform, the first segment with 
feeble and sparse punctures; the remaining segments 
seem to be impunctate; ventrally the second segment has 
a few scattered punctures; wings subhyaline, nervures 
and stigma honey-yellow: two submarginal cells; head, 
thorax and abdomen of a ferruginous brown, the antenne, 
palpi, tegule and legs honey-yellow: ocellar region and 


HYMENOPTERA FROM LOWER CALIFORNIA. 7 


sides of abdomen faintly blackish; the whole insect is 
clothed with a long, pale pubescence; segments of ab- 
domen not fringed. Length, 16 mm. 

Two specimens. San José del Cabo, L. Cal. (#7sev). 
In one specimen the ridges on metathorax are very 
short. 

BRACHYCISTIS gen. nov. 

General appearance of Photopsis. Width of the head 
variable. Eyes large rounded-ovate, their inner margin 
sinuous. Ocelli large, prominent, placed in the form of 
a triangle. Antenne long, 13-jointed, situated very low 
down, its scape and pedicellum united shorter than first 
joint of flagellum. Mandibles strong, tridentate at apex. 
Pronotum situated far below level of dorsulum, which ts 
very strongly convex; wings ample, st7zgma large, one very 
short, truncate marginal, which has a short appendicu- 
lation at apex; three submarginal cells, the second of 
which is usually triangular and sometimes petiolate, ve- 
current nervures received by the second and third submar- 
ginal cells. Legs not spinose, the middle tibia with one 
spur, their coxe tolerably well separated. ‘Tarsal claws 
curved, unarmed. Abdomen elongate, the form of the 
first segment varying from petiolate to sessile with the 
second segment, at the apex there is a single strong 
curved hook or spine, which projects beyond the seventh 
ventral segment and curvesupward. Size variable, 6-15 
mm. Type, B. petzolatus n. sp. 

This genus, the 4 only of which is known, as is like- 
wise the case with several other allied genera, looks on 
first sight to be Photopsis, but the larger stigma, the re- 
current nervures being received by second and third sub- 
marginal cells and the one-spurred middle tiba, will at 
once distinguish it. The sculpture is much less strongly 
marked than in Photops7s, some species being very smooth

and glabrous. Into this genus will fall the following 
species of Photopsis: 

P. ampla Blake, nztida Cresson, alcanor Blake, atrata 
Blake, sobrina Blake, /epida Blake, castanea Cresson and 
glabrella Cress. and the following new species: 

BRACHYCISTIS PETIOLATUS N. sp. 

6 .—Black, the antennz, mandibles, tegule and legs 
except coxe and hind femora medially, pale-testaceous; 
the pro- and metathorax, first segment of abdomen, coxe 
and hind femora medially, castaneus; the whole insect is 
sparsely clothed with long, pale-fuscous hairs; dorsulum 
indistinctly punctured, the mesopleure distinctly so; 
metathorax coarsely granulated or roughened, impressed 
medially, the sides smooth: wings hyaline, stigma pale 
testaceous, marginal cell very narrow, second submar- 
ginal cell with a long petiole; abdomen petiolate, the first 
segment or petiole thickened to the apex and is coarsely 
punctured. Length 7-8 mm. .

MoNEDULA MAMMILLATA Hand. 

I very doubtfully refer three male specimens from 
Lower Purisima, L. Cal. (/faznes) April, to this species. 
While agreeing tolerably well with the description of 
mammillata, yet the markings on abdomen are different, 
and when the locality of mammzllata (Georgia) is con- 
sidered, I scarcely think these specimens are that species. 
For the present, however, I can do nothing more than re- 
fer them to it. 


BEMBEX OCCIDENTALIS N. sp. 

? .—Black, the head, thorax and first abdominal seg- 
ment rather densely clothed with ashy pubescence, which 
is longest on front and vertex; clypeus, labrum, man- 
dibles except tips, inner and posterior orbits, scape ex- 
cept black line above, flagellum beneath, prothorax ex- 
cept the middle anterior portion above, tubercles, large, 
somewhat angular mark on mesopleure, a smaller spot 
behind it beneath the wings, greater part of tegule, a line 
on each extreme side of the dorsulum, narrow line on 
posterior portion of scutellum and post scutellum, that on 
the former formed into a spot on each side, a transverse, 


HYMENOPTERA FROM LOWER CALIFORNIA. at 


curved line, extending from side to side at apex of upper 
face of metathorax, large spot on metapleura which is 
emarginate above, legs entirely, including the coxe, a 
broad fascia on abdominal segments 1-5, that on the first 
greatly narrowed medially, that on the second scarcely 
narrowed, but enclosing two transversely-ovate black 
spots, on third, fourth and fifth segments the fascie have 
two strong emarginations on anterior margin and a weaker 
one on posterior margin in the middle, sixth dorsal seg- 
ment entirely and fascize on ventral segments which (the 
fascie) are more or less variable, all sulphur-yellow; 
wings clear hyaline, nervures brownish; antenne rather 
long, reaching beyond the tegule, the first joint of flagel- 
lum fully as long as the second, third and half of the 
fourth united; clypeus and labrum indistinctly punc- 
tured; thorax microscopically punctured; posterior face 
of metathorax with a large triangular depression at top; 
tibiz and tarsi strongly spinose; anterior tarsi with a 
well developed comb, the spines of which are shortest 
basally, the longest spines equal fully the length of the 
first joint; abdomen very finely shagreened. Length 
21-23 mm. 

6 .—Markings and coloration similar to the female, al- 
though the coxe and trochanters are more or less black; 
antenne scarcely reaching beyond tegule, joints 7-9 
dentate beneath; legs armed as in the female; second 
ventral segment with a strong, longitudinal central keel, 
which is more prominent apically; sixth ventral with two 
approximate teeth, which, when viewed from the side, 
appear as one. Length, 20-21 mm. 

Reno, Nevada (//7//man); California (coll. Am. Ent. 
Soc:), and San José del Cabo, L. Cal. (Zzsen). Related 
to and closely resembles B. nudbilipennis Cress., from 
which it usually can be distinguished by the hyaline wings: 


I2 CALIFORNIA ACADEMY OF SCIENCES. 


however, the wings of xabz/cpennis are sometimes hyaline, 
so too much reliance must not be placed on that charac- 
ter. The greater length of the antenne and longer tarsal 
comb will help in separating the females, while the form 
of armature on ventral segments two and six will dis- 
tinguish the males. 


BremsBex Luc Cress. El Paraiso and San Borgia, L. 
Cal. (Hames). May. This species seems to be unde- 
scribed, the name Luce being a manuscript one. 


GORYTES EXIMIUS Prov. Onefemale. El Paraiso, L. 
Cal. (//aznes). May. 


MASARIDZ. 


MASARIS MACULIFRONS N. sp. 

¢.—Head and thorax with coarse, close punctures, 
having the appearance of being granulated, the punctures 
most distinct on the prothorax above and on the dorsulum 
anteriorly; abdomen with exceedingly fine and close 
punctures; marginal cell truncate at tip; deep black, sub- 
opaque; a large semi-oval spot on clypeus at base (the 
sides of the spot are emarginate), a pyriform spot just 
above the insertion of antenna, a spot in the eye emargin- 
ation, posterior orbits narrowly, an oblique elongate mark 
on each shoulder, posterior margin of pronotum, outer 
margin of tegule, large spot on mesopleure, spot at 
apex of scutellum, and the angles of the metathorax 
whitish; abdominal segments 1-5 above with their apical 
margins whitish, that on the first, second and third seg- 
ments interrupted on each side of the middle, so that it 
represents three separate marks or spots, the laterals of 
which are largest, ventrally the second segment has a 
small spot on each extreme side, the third with a medially 
interrupted fascia at apex, and the fourth with four small 
spots, all whitish; the head and thorax are clothed with 


HYMENOPTERA FROM LOWER CALIFORNIA. 1 34 


a short, erect pale-fuscous pubescence, wings subhyaline, 
fuscous in places, iridescent, stigma ferruginous, nervures 
black; tibiz and tarsi more or less ferruginous. Length, 
II mm. 

El Paraiso, L. Cal. (Haines). May. Related to ™. 
marginalis Cresson, from which it may be distinguished 
by the spots on clypeus and scutellum, and by the coarse 
sculpture of head and thorax. From the other North 
American species, the white ornamentation will distin- 
guish it.

ON A COLLECTION OF FORMICIDA FROM LOWER 
CALIFORNIA AND SONORA, MEXICO. 


BY THEO. PERGANDE. 


The determination and description of Formicide can 
only be accomplished in a satisfactory way if large series 
ot specimens, taken from the colonies, are available for 
examination and comparison. It was with some reluc- 
tance, therefore, that I have undertaken the task of de- 
termining the small collection of ants which was brought 
together by Mr. Gustav Eisen and Mr. Chas. D. Haines 
of San Francisco, Cal. If I have ventured to describe 
some of the species as new, it has been done after a 
thorough study of the literature on the subject and after 
a careful comparison with the material at my command. 


FORMICIDE. 


I. CAMPONOTUS MACULATUS Fab., race OCREATUS Em. 

One 8 major, one & minor. San Luis and San Es- 
teban. 

This race is found as far north as the Panamint Mount- 
ains, Cal: 

The description of this new race by Prof. C. Emery 
will shortly be published in the Zoologische Jahrbicher. 


2. CAMPONOTUS FRAGILIS N. sp. 

S major: Length, 7-9 mm. MHoney-yellow; posterior 
angles of the head, the femora and scale somewhat paler ; 
the face between the eyes, the clypeus, disk of pro- 
thorax and the abdomen above, except a broad anterior 
margin of the second and third segments, brownish. 
Scape blackish beyond the middle. Eyes black. Man- 
dibles reddish. Pubescence yellowish, long and slender, 
densest on the head, thorax and abdomen, sparse along 
external edge of anterior femora, with a few hairs only 
at the basal third or fourth of the external edge of the 


2p SER., Vou. IV. September 19, 1893.

median and posterior femora. A few shorter and stiffer 
hairs may also be observed at the apex of the femora. 
Appressed pubescence minute, intermixed on the scape 
with fine, erect hairs. Head about one-third broader 
than the thorax, broadest at posterior angles and gently 
decreasing in width towards the mandibles, emarginate 
behind, with the posterior angles rounded. Clypeus trun- 
cate in front, its median carina distinct. Surface of head 
and thorax densely and finely granulated and sparsely 
punctured. Abdomen with a still finer sculpture and 
somewhat transversely striated. Mandibles smooth, with 
scattered piliferous punctures; their apical edge with six 
black teeth. Antenne slender, the scape reaching a 
little beyond the posterior angles of the head. Scale 
ovoid, broadest beyond the middle, stoutest at base, 
slightly arcuate in front, almost straight behind. Legs 
long and slender. 

6 minor: Length, 5-7 mm. General color somewhat 
paler than in the 8 major, the head and thorax without 
darker shadings, the abdomen either faintly brownish 
or only the sutures somewhat darker. Median and pos- 
terior femora almost white. Head about twice as long 
as broad, scarcely broader than the thorax; its sides 
parallel, rounded beyond the eyes. Antenne longer and 
more slender, the scape reaching nearly to the meso- 
thorax. 

It is a very delicate looking species. 

The % minor resembles very much that of Camp. 
melleus Say, though it is smaller, more delicate, with 
the head not emarginate. Camp. melleus differs from it 
also in the absence of erect hairs on the scape and in the 
stouter scale. 

This species resembles also somewhat Camp. atlantis 
Forel, differing from it however in the form of the cly-

extended beyond the insertion of the mandibles.

This variety is black and polished, with the scape of 
the antenna and the legs dark brownish. 

Similar forms are found at Washington, D. C., and in 
Florida. This form differs from them, however, in hav- 
ing a distinct constriction or suture between the meso- 
and metanotum and in the shape of the scale. It may 
possibly represent a new species, though I am not pre- 
pared to describe it as new from a single specimen. 


5. CAMPONOTUS ERYTHROPUS D. sp. 

% major, 5-7 mm; & minor,4—5mm. Opaque black, 
the abdomen slightly polished. Mandibles and anterior 
margin of head dark cherry-brown. Antenne, tibia and 
tars1 reddish, the tarsi somewhat darker; rest of legs 
black. In the smaller specimens the middle and posterior 
tibia are sometimes blackish beyond the middle. Eyes 
brown. Pubescence white, glistening, rather long and 
quite profuse. Hairs on the head above insertion of an- 
tennze as well as those on the thorax and base of first 
abdominal segment finer and more slender than those on 
the abdomen. Hairs in front of the insertion of the an-

tenne and those on the mandibles, short and stiff. Pu- 
bescence of the legs still shorter and more or less ap- 
pressed, excepting a few longer and erect hairs at the 
knees; a few longer hairs may also be observed on the 
scape of the antenne. 

Head of % major about one-half broader than the 
thorax, though but slightly broader in the % minor; shghtly 
longer than wide, somewhat broadest behind; its sides 
above insertion of the antenna almost parallel, gently 
curving towards the mandibles, distinctly emarginate

The genus Tapinoma, as far as known at present, is 
represented in North America by but one species with 
numerous varieties, varying in size and coloration, all of 
which pass so gradually from one to the other that it is 
almost hopeless to separate them satisfactorily. The 
present form is smaller and paler than most of those 
found in the United States, and comes nearest to var. 7. 
boreale Rog.; I hesitate, therefore, without having a 
knowledge of the sexes, to describe this form as new.

behind; a rather broad, shallow frontal channel and 
laterally carinated area beyond insertion of antenne. 
Posterior angles of head rounded and with a row of six 
or more short denticles, the last one somewhat longest; 
three or more teeth may also be observed along the pos- 
terior ventral edge each side, the anterior one of which 
being longest. Frontal lamina broad, somewhat longer 
than wide, bifid at upper angle; interno-ocular carina 
distinct, curved inwards. -Clypeus broadly triangular, 
slightly arcuate in front, with a slight median emargina- 
tion. Mandibles large, triangular, their apical edge al- 
most straight and furnished with four to six blunt, rudi- 
mentary teeth. Scape of antenne rather short, reaching 
but little beyond posterior angles of the head. Thorax 
of the usual shape in this genus. 

Prothorax with two stout spines each side, the anterior 
pair farthest apart, longest, inclining forward, the other 
two stouter, directed backward and outward; two short,

front of the middle of the mesothorax and a still shorter 
one each side of them at the anterior margin. Meta- 
thorax with a deep median depression, the upper edges 
quite acute, terminating anteriorly in a small tooth-like 
projection. Metathoracic spines rather long and slender, 
curved backward and outward.

acute ventral tooth at base. Second node wider than 
long, rounded in front and at sides, truncate behind, con- 
cave above, the edges acute and beset with four or five 
short, acute teeth; there is also a prominent lateral carina, 
furnished with four or five teeth, and two ventral teeth.

a depressed median line, and each lateral half with about 
twenty-five teeth, some of them bifid, arranged in irregu- 
lar rows. The other segments without teeth or tubercles.

metathorax, legs, nodes and abdomen densely and finely 
granulate. Erect pubescence stiff and blackish, the 
appressed pubescence yellowish.

This appears to be related to A. coronata Fab., which 
differs from this species in the comparatively smoother 
surface of every part of the body, the longer mandibles

TUNICATA OF THE PACIFIC COAST OF NORTH 
AMERICA. I.—PEROPHORA ANNECTENS N. SP. 


BY WILLIAM E. RITTER. 


While the summer work in biology of the University 
of California was being carried on at Pacific Grove, dur- 
ing the month of July, 1892, my special attention was 
given to the Tunicates of that locality. All the rocky 
shores of Monterey Bay, particularly those of the south- 
ern, or Monterey side, are very rich in this group of 
animals. 

A large collection was made by myself and students, 
and the paper here presented is a portion of the results 
of the study begun on the living animals at the seaside, 
and continued on preserved material brought back to 
Berkeley. In my efforts to reach conclusions concerning 
the variations that were early found to be conspicuous in 
the form under observation, I have been able to compare 
a larger number of individuals than would have been 
possible but for the assistance rendered me by one of 
my students, Mr. S. J. Holmes, who has prepared many 
specimens for examination. I may here say, however, 
that although I have examined many hundreds of indi- 
viduals, and with considerable detail, as far as general 
anatomy is concerned, I am satisfied that I have not pur- 
sued the subject to the extent that it deserves. I antici- 
pate that further study along this line will yield interest- 
ing results. 

The species in hand is a Perophora, as I believe the 
sequel will show to the satisfaction of every one acquainted 
with this genus and its nearest congeners. But the in- 
teresting fact may be pointed out at once that the char- 
acteristic of chief importance for distinguishing it from 
the other species of the same genus, would, according to 

2D SER., VOL. IY. October 26, 1893. 


38 CALIFORNIA ACADEMY OF SCIENCES. 


some of the schemes of tunicate classification recognized 
at present, place it ina different family from that to which 
the genus Perophora is assigned; or, by other schemes, in 
a different suborder. The character to which I refer is 
this: J/z very many, though not all, of the colontes the 
ascediozoords are as completely imbedded in a common test 
as they are tn Botryllus or Goodstria. 

The distinction between ‘‘ simple ’’ and ‘* compound,”’ 
as applied to Ascidians, the importance of which has 
diminished in the same ratio that our knowledge of the 
group has increased, is reduced to 27/ by the discovery of 
this form, so far as its value in determining affinities is 
concerned. 

Down to Savigny’s time (716) the compound Tunicates 
had not been distinctly recognized as Tunicates, but had 
been generally regarded as Alcyonaria. This author 
made clear their true nature, and grouped them together 
under the name 7¢¢hys composées, as opposed to the 7¢thys 
simples .* 

After this Lister (°34) made the first of the long series 
of discoveries that has finally resulted in establishing a 
most perfect gradual transition from the one group to the 
other. Itis an interesting fact that his discovery was 
that of the first Perophora known to science. In it he 
showed that the ascidiozooids of a colony are all con- 
nected together by stolons, through which the blood flows 
constantly and regularly from one to another. Clavelina 
was known to Savigny, but he seems not to have been 
aware that it reproduces by gemination, and he placed it 
among his 7¢¢hys semples. ‘The discovery of this latter fact 
was made by Milne-Edwards (’42). This author invest- 
igated this and its allied forms in his usual careful manner, 


“I have not had access to any of Savigny’s original works, but take this 
from Jones (48, pp. 5 and 7). 


PEROPHORA ANNECTENS. 39 


recognized its intermediate position between the simple 
and compound Ascidians, because of its power of repro- 
ducing by budding, and in conclusion he says: ‘“ Je 
proposerai aussi de donner a ce groupe intermédaire le 
nom de: SECTION DES ASCIDIES SOCIALES’’ (p. 266). 
And in this new section he placed also the one species ot 
Perophora then known. The two divisions of Savigny 
were retained, with simply the substitution of the name 
ewAgcigies . dor ° sl éthys.+ 

These three co-ordinate sections, thus established by 
Milne-Edwards, were recognized by many writers, and 
not particularly opposed by any, until Herdman’s (80) 
preliminary report on the Tunicates collected by the 
Challenger Expedition was made. In this collection this 
author discovered a new genus, belonging to the same 
family as Clavelina, named by him Ecteinascidia, which 
difters from Ciona, a genus of simple Ascidians, 
chiefly in the fact that it reproduces by budding. But 
he affirms that both Ciona and Ascidia are sometimes 
found to possess stolons (’82, p. 238). He concluded 
that the transition between the ‘‘Asczdzes simples’? and 
the ‘*Ascrdies sociales’’ of Milne-Edwards is so complete 
that the latter can no longer be regarded as a natural 
group. He therefore discarded it and united all the 
genera included in it (Herdman, ‘91, p. 599*, and Gars- 
tang, 91, pp. 50, 57 and 62), in one family, the Clavel- 
inide of the Ascidiz Simplices. 

Finally, Garstang (91, pp. 48 and 49) declares it as his 
belief that ‘‘ the division of the Ascidiacea into the sub- 
orders Ascrdie@ simplices, Ascidie composite and Ascidie 


* The conjecture here made by Prof. Herdman, that Clavelinopsis rubra 
Fewkes, from the California coast, does not belong to the Clavelinide, is 
correct. It is not a Bo/tenia, however, but a Styela, probably an unde- 
scribed species, though I have not yet studied it with sufficient care to say 
with certainty. 


40 CALIFORNIA ACADEMY OF SCIENCES. 


salpiformes, so completely disregards the admitted inter- 
relationships between various sections of these groups, 
that its adoption seems to me to involve the rejection of 
any morphological, and therefore genetic, meaning in 
classification altogether.’’ This author, therefore, drops 
these three suborders entirely, and simply groups the 
genera together into families. 

As already said, incidentally, the first Perophora was 
described by Lister (’34). He did not name it, however, 
this having been done by Wiegmann (735 ),who established 
the genus for it and designated it specifically by the name 
of its discoverer. 

Since that time, three more undoubted species, includ- 
ing the one that is the subject of the present paper, have 
been added to the genus. 

The first of these three, P. Wutchinson7, from Austra- 
lia, was described by Macdonald (’59). The second, 
from the New England coast of North America, was de- 
senbed by Verrll (71).0  Whistise?:. wexcdes. 

In recognition of the interesting transitional character 
of the one here made known, I propose for it annectens 
as a specific name. 


DIAGNOSIS OF THE SPECIES. 


Colonies irregular in form and size, the larger ones two or more inches in 
length. Mostly encrusting on sticks, stones, sea weeds, and on other 
Tunicates, particularly Clavelina. Color—pale greenish yellow. 

Zooids about 14 mm. long by 1 mm. wide, short-oblong, laterally com- 
pressed, generally crowded together, and wholly embedded in the com- 
mon test, but frequently remote and with only the basal portion of the 
body embedded in the thick testicular mass surrounding the stolons. 

Test mostly thick, forming a common envelope for the ascidiozooids and 
stolons. Transparent. 

Stolons much branched, anastomosing freely, provided with numerous 
lateral and terminal knobs, these confined to the layer of test corres- 
ponding to the bases of the zooids. 


PEROPHORA ANNECTENS. 41 


Apertures both terminal, branchial six lobed, atrial five or six lobed 
(though the number of lobes is not constant for either orifice). A ya- 
riable number of yellow pigment spots on the lobes of the branchial 
opening. 

Tentacles about twelve in number (frequently more), of different lengths, 
irregularly scattered on the inner surface of the branchial siphon. 
Irregular in arrangement. 

Branchial Apparatus. Stigmata in four circles, about eighteen in each 
half circle. Horizontal membranes present. Internal papille con- 
spicuous, each consisting of a post-like connecting bar, from near the 
inner end of which project two processes, the one anterior, the other 
posterior. Dorsal languets three in number, one for each transverse 
vessel. Each turned to the right side. 


Duct of the neural gland is funnel-shaped, opening to the right of the 
median line. 

Genitalia situated in the loop of the digestive tube, the testes exceedingly 
variable as to the number of its lobes, from one to eight having been 
observed in different individuals. 


I. GENERAL DESCRIPTION. 


As thus defined, the species is not certainly known to 
exist elsewhere than in Monterey Bay. I have collected 
Perophora at Point Reyes, north of San Francisco Bay, 
and at Santa Catalina Island, off the coast of Southern 
California. But at neither of these points, nor elsewhere 
on our coast, though I have searched quite carefully at 
several places, have I found the compounded form. In 
addition to the difference in this regard, there are cer- 
tain other differences, greater or less in different colonies, 
and apparently different localities, that may be sufficient 
in extent and constancy to make it worth while to recog- 
nize other species than the one now described. 

I leave the question as to what shall be done with the 
Perophora of our coast that can hardly, in the present 
state of our knowledge, be included in the new species, 
as I have defined it, because it seems to me wiser to ten- 
tatively leave a partially known group without a name, 
pending further investigation, than to tentatively name 


42 CALIFORNIA ACADEMY OF SCIENCES. 


such a group, as is the practice of systematists in some 
quarters, with a large probability that the literature of the 
subject will thereby be permanently befogged for future 
students. 

At extreme low tide, the species is abundant at Pacific 
Grove, though rather less so than numerous other 
species of compound Tunicates with which it is associated. 
It grows upon rocks, sea weeds, larger sertularian 
hydroids and other common objects of the shore, but 
particularly on another Tunicate, a large, undetermined 
species of Clavelina, that is common here. To what 
depths it extends I do not know. None have been taken 
by the dredge, for our dredging at Monterey was con- 
fined to sandy bottoms where the Perophora would not 
be likely to occur to any considerable extent. 

The colonies in which the ascidiozooids are most com- 
pletely embedded in the common testicular mass and are 
most crowded, are found on such objects as present a 
rather even surface, over which they may spread. Thus 
in many instances the large individuals, an inch and more 
in length, of the Clavelina, already mentioned, are found 
to be almost completely covered over by a coating of the 
Perophora colony. 

Fig. 2, pl. i, represents asmall portion of a colony of this 
kind, twice its natural size, situated ona twig of sea weed. 
Only the basal portion of the colony is figured, the pur- 
pose being to show not only the crowded condition of the 
zooids, but also the fact that a few individuals (7. zo.) of 
the colony are isolated. It should be mentioned, how- 
ever, that in no case have I found one of these isolated 
zooids, in a colony of this kind, raised at all from the 
stolon ona peduncle, as is the case in some of the species 
ofthegenus. Fig. 4, pl.i, represents the margin of another 
colony of the same kind on a leaf of eel grass. The con- 


PEROPHORA ANNECTENS. 43 


dition here shown is quite characteristic. At the extreme 
edge of the colony there is a narrow, irregular belt of the 
testicular mass, in which only the stolonic vessels with 
their numerous short, knob-like: branches, their anasto- 
mosings, and young zooids are seen. This is Par excel- 
lence the growing region of the colony. One rarely, if 
ever, finds young buds in other than this marginal zone, 
though in some cases they are found in what might be 
called the proximal portion of the colony, where there 
are long stretches of stolonic vessels bearing few zooids. 
The region in which the isolated zooids are shown in fig. 
2 is one of this kind, and some of these are not fully de- 
veloped. Why few or no zooids are present in these re- 
gions I am not sure, but think it possible that they have 
died and fallen away. It will be seen in fig. 4, pl. 1, that the 
vessels do not extend into the test which is situated around 
and between the zooids; they are confined, for the most 
part, to the layer that forms the contact with the substratum 
of the colony. Their branching is mostly in a plane par- 
allel to the surface on which the colony rests. his latter 
condition is well shown by the section represented in fig. 7, 
pl. i. A section of a portion of the testicular mass in which 
zooids are present, but vessels are not, is shown in fig. 5, 
pl.i. In some cases, the partition of test that separates two 
zooids is exceedingly thin, while in other cases it is of 
considerable thickness. In certain colonies, the zooids are 
so closely crowded together that they appear on cursory 
examination to have acommon test; more careful inspec- 
tion, however, discovers that this is not so; that the test is 
not continuous from zooid to zooid; they are only in con- 
tact with oneanother. This having been found to be the 
case in some colonies, it seemed quite possible that in other 
cases, where the test appeared to be a unit for the whole 
colony; where the zooids could not be separated by me- 


44 CALIFORNIA ACADEMY OF SCIENCES. 


chanical means, that this might be due to a still closer 
crowding together of the zooids, and that sections would 
reveal planes of contact between the tests of the different 
individuals. However, such examination proves beyond 
the possibility of a doubt that no such contact planes 
exist. As is shown by fig. 5, pl. i, which is drawn 
from a section of one of these colonies, the test is con- 
tinuous from one zooid to another, entirely without inter- 
ruption. 

From the facts thus presented, the question arises, has 
this fully compounded condition been produced by such a 
crowding of the adult zooids of the colony that the tests 
have become fused by mutual pressure, aided, perhaps, 
by the constant renewal of the test by growth? Is 
it not possible that since these individuals of a colony 
have a common blood system, their tests grow together 
when brought in contact, after something the same fashion 
that the severed surfaces of a wound grow together when 
brought in contact? And it is possible that the process 
may be assisted by the slight irritation that would be pro- 
duced on the surfaces in contact. One fact seems to 
favor such a view. Colonies may be found in which the 
individuals, though each possessing its own test, are still 
so closely pressed that they adhere to one another to such 
an extent as to admit of separation only with considerable 
force. That complete obliteration of the plane of contact 
ever takes place in this manner, I have, however, not 
been able to demonstrate. But even if the compound- 
ing is ever produced in this way, or was so produced 
phylogenetically, it is very easy to show that it is not now 
so produced ontogenetically. The developing individuals 
in these colonies are from the beginning as completely 
buried in the common test as are the adults. Figure 1 
represents a small portion of the tip of one of the much 


PEROPHORA ANNECTENS. 45 


crowded, but not compounded colonies. This is natural 
size, and the number and arrangement of the zooids are 
reproduced as faithfully as possible. 

The appearance of the zooids when taken from the 
test is fairly well represented by fig. 3, pl. i, the outlines 
of which were drawn by the aid of a camera lucida. As 
compared with the other known species of the genus, the 
approximately spherical form and the terminal position of 
both orifices are noticeable. When the anterior end of 
the fully expanded living zooid is looked down upon, the 
outline presented is that of a rather broad ellipse with the 
two orifices situated at the foci. 

The ease with which the zooids can be removed from 
the test in the fully compounded colonies is worthy of 
mention. In a preserved colony that has been cut in 
pieces, they may be picked from their little cavities in the 
test, reminding one of the way in which very young frog 
embryos may be picked from their gelatinous envelop. 
The only points at which they seem to be adherent are 
the extreme edges of the orifices, and the point of pas- 
sage of the blood vessel from the body into the stolon. 
When we come to examine the minute structure of the 
test and the body layer in contact with it, we shall see 
that the union between the two is much more intimate 
than appears on gross dissection. 

Another point to which attention may well be called 
in connection with the general appearance is the course 
of the transverse vessels of the branchial sac. The body 
is sufficiently transparent to permit these to be seen with 
considerable distinctness in a good light. As may be 
seen by fig. 3, the planes of these circular vessels are 
not situated at a right angle to the antero-posterior axis of 
the body, but they all converge on the dorsal side of it. 
This convergence is associated with a slight dorsal curv- 


46 CALIFORNIA ACADEMY OF SCIENCES. 


ature of the antero-posterior axis itself. As compared 
with the form, of -P..“zsfe72, (ister) 345 \pll. taaiyaio ge) 
it is as though the dorsally directed atrial siphon of this 
latter species had been brought to an anterior direction 
by bending dorsalward the entire posterior portion of the 
body. When well distended, the siphons are distinct in 
specimens removed from the test; and in such cases the 
marginal lobes of them, though not large, may yet be 
clearly seen with a slight magnification. In the individual 
shown in fig. 3 there were six lobes on the branchial 
siphon and five on the atrial. These are the most usual 
numbers, but they are not altogether constant. In several 
instances I have found six on the atrial also. The size 
of the lobes and the spacings between them may vary 
considerably. Thus it will be observed in fig. 3, that 
the interval between two of the atrial lobes is considerably 
wider and deeper than are those between the others. 


2. THE LEST AND THE ORIGIN OF ITS) CELLS: 


In a majority of the sections which I have examined, the 
test presents a uniformly hyaline matrix, in which are 
scattered a few cells (figs: 29, 30,31 and 32, Zs... 7765) 
The structure is not, however, so simple as this in all 
cases, for in several instances a vast number of exceed- 
ingly fine granules have been found in the matrix. This 
condition I first observed in sections stained on the slide 
in Delafeld’s hematoxylin; and as the granules appeared 
to be of the color of the stain, I was inclined to think that 
they had been deposited from the stain. However, 
further examination of sections stained by various other 
methods shows that this, at least, is not their origin. In 
some cases they are not stained at all, but are seen be- 
cause of their being somewhat more refractive than the 
testicular matrix. They are not cut fibers, since they 


PEROPHORA ANNECTENS. 47 


never show as anything else than granules. They are so 
excessively small that I have not, even witha ;y oil 
immersion objective, been able to determine much of their 
nature. From what I have seen in a single specimen 
‘stained in borax carmine, I have thought it possible that 
they may be bacteria. My grounds for this conjecture 
are not, however, very good. 

It is a fact worth mentioning, perhaps, that in many 
cases there is a layer on the external surface of the test 
that takes the stain considerably more readily than do its 
remaining portions. This I have observed in sections 
stained in various ways. The layer is not, however, an 
external epithelium, such as is described by Maurice 
(788, p. 58), in the larva of Fragroides. There is, I be- 
lieve, but one kind of cells in the test, and this is an im- 
portant fact in connection with what I shall maintain to 
be their origin. Figs. 29 and 30, pl. 111, represent portions 
of test containing several of these cells. The figure was 
drawn with great care, with the aid of a Powell and Le- 
land ,', oil immersion objective. The more usual condi- 
tion is that shown in fig. 29. Here the cells are seen to 
be situated in cavities which they do not fill. The nuclei 
are by far the most distinct parts of the cells. Indeed, it 
is not until one examines them very carefully with high 
magnification and with the most favorable light, that he 
is able to convince himself that a cell-body can be seen 
at all. 

I have not attempted to represent the spaces in which 
the cells are situated in any of the other figures, and in 
many cases they cannot be seen. Occasionally one finds 
cells in which the protoplasm is stained somewhat, though 
never so deeply as the nucleus. Instances of this kind 
are Seen at 7..¢., igs. 29 and 30. It happens not in- 
frequently that two cells are found in one capsule (fig. 


48 CALIFORNIA ACADEMY OF SCIENCES. 


29). It is probable that division has recently taken place 
in such cases, though I have never noticed a cell in the 
act of division. 

Two papers have recently appeared which call seri- 
ously in question the view generally held by students of 
the Tunicata that the cells of the test are of ectodermal 
origin. The papers referred to are those of Salensky 
(91) and Kowalevsky (’92). The first-mentioned author 
refers to the fact that Della Valle has observed the wan- 
dering out of ectodermal cells from the ectoderm into the 
‘* cellulose mantel,’’ there to become transformed into the 
cells characteristic of this layer, and he then adds: ‘‘ Ich 
kann eine solche Auswanderung auch fiir die Pyrosomen 
gelten lassen, muss aber annehmen, dass der grosste 
Theil der ausserhalb des Cyathozoids lhegenden Zellen 
von asgewanderten Mesenchymzellen stammt ”’ (p. 12.) 
‘* Wenn diese Zellen auswandern, so kann man sie leicht 
zwischen den Zellen des Ectoderms erkennen, und 
dadurch wird die Entscheidung der oben aufgestellten 
Frage tiber die Natur der ausserhalb des Embryos le- 
genden Zellen bedeutend erleichtert ’’ (p. 13.) 

And the author illustrates the conditions thus described 
by figs. 30a and 31. 

It was with special reference to this point that Kowal- 
evsky’s paper was written, and he dwells upon it in his 
text and illustrates it in his plates so fully that there can 
be no doubt that in the larval development of Pha//usza 
mammilata the species in which he studied the question, 
cells of the test are derived from mesenchyme cells which 
migrate through the ectoderm. 

‘¢ Somit steht es,’’ writes the author (p. 7), ‘‘ wenigsten 
fiir die einfachen Ascidien und speciell fiir Phallusia fest, 
dass deren Mantelzellen aus dem Mesoderm abstammen; 
allen Wahrscheinlichkeit nach wird sich derselbe Process 


PEROPHORA ANNECTENS. 49 


auch bei den socialen und zusammengesetzten Ascidien 


99 


constatiren. Salensky’s paper having appeared about 
the time, or only shortly before Kowalevsky’s observa- 
tions were being made, the latter seems not to have been 
aware of what the former had said on this point. 

As the testicular mass in these fully compounded col- 
onies of Perophora is presumably growing constantly, it 
seemed to me that they offered a good opportunity for 
testing the assumption of Kowalevsky, quoted above, that 
in the social and compound ascidians, also, the test cells 
have a mesodermal origin. I have accordingly studied 
the point with considerable care, with what results the 
sequel will show. 

The cells of the test of the growing colony must be 
derived from one or more of three sources: First, they 
may be the direct descendants of the original cells of the 
test of the larva from which the colony has been produced. 
Second, they may arise by division from the growing por- 
tions of the epithelial linings of the stolonic vessels, or, 
what is the same thing, the external epithelium of the 
body of the zooid. This epithelium is ectodermal, as we 
know from the method of development of the stolon, as 
first shown by Kowalevsky (’74). Third, they may arise 
from the mesenchymatous cells contained in the blood. 

Their origin by the first method I can neither affirm nor 
deny, as I have studied neither the development of the 
larva nor its first-formed stolons. Even if some of them 
do have this origin, certain it is that not all of them do, 
as the following account will show. 

Their origin by the second method, 7. e., from the 
ectoderm, I fully believe does not take place. I have 
searched through many sections prepared by many meth- 
ods for evidences of it, but have failed utterly to find it. 


There remains, then, only the third method by which 
2p SER., VOL. IV. (4) October 26, 1893. 


O CALIFORNIA ACADEMY OF SCIENCES. 


on 


they may originate. The evidence on which I base my 
belief that they arise by this last method is threefold: 
First, the cells of the test are wholly unlike the cells of 
the endothelial lining of the stolonic vessels, even at the 
tips of the vessels where the endothelium is thickened 
because of the growth that is there taking place. Both 
the endothelial cells and the test cells are shown in figs. 
30 and 31, ed.v. The former invariably contain large, 
clear nuclei, usually spherical in regions where growth is 
taking place, but sometimes slightly flattened in the plane 
of the membrane to which they belong. These nuclei 
are from 4 ». to 6. in diameter. Each contains one 
large distinct nucleolus. The cell protoplasm, which is 
in considerable quantity, stains more distinctly than does 
the nuclear matter. There is no cell membrane, and the 
cells are irregularly stellate in form, this form being de- 
termined in part, no doubt, by mutual contact, though in 
preserved specimens they do not appear closely crowded ; 
in fact (fig: 3%, pl.. 11) there are often seen aurregulan 
spaces between them. This is probably due to slight 
shrinkage. 

The nuclei of the test cells are, on an average, about 
one-half the size of those just described, z.¢., 2% yp. in 


? 


diameter. (Bigs. 29, 30.and 31; 2. G2, mm. G. and 77miG-s) 
A nucleolus can usually, though by no means always, be 
detected; but nearly the whole body of the nucleus stains 
deeply, so that the nucleolus is never seen in the midst of 
a large clear space, as in the case of the nuclei of the 
endothelium. In by far the greater number of instances 
the cell-body is not seen at all, excepting by the greatest 
care and with the aid of high powers and favorable light. 
When recognizable, it is sometimes disposed in a uniform 
layer around the nucleus, giving the cell, as a whole, an 
approximately spherical form; but, more commonly, one 


PEROPHORA ANNECTENS. 51 


or more blunt processes are seen projecting from it. As 
already said, these cells are very frequently situated in 
spaces, or capsules in the test matrix. Whether this is 
wholly due to the shrinkage of the cells I am not sure. 
Even when these cells are found so close to the endothe- 
lium as to be actually in contact with it, as very frequently 
happens, they are still of the same form, size and struct- 
ure. This, of itself, is strong evidence against their 
having arisen from this endothelium. It is almost con- 
clusive proof that they are not endothelial cells which 
have migrated into the test; and if they had arisen from 
these cells by division, it would still seem improbable that 
they should at once be so different from their mother 
cells. Again, it would seem that if they have such an 
origin, cases in which the division is going on might be 
found. Although I have searched diligently for such 
cases my efforts have been in vain. 

My second reason for believing the cells of the test to 
be derived from the contents of the vessels and the body 
spaces is that cells are found here which are, so far as lam 
able to make out, precisely similar to the test cells. Figs. 
30 and 32, m. c’., pl. iii, show some of these, or rather their 
nuclei, in the first figure taken from one of the stolonic 
vessels, and in the second from the body space in the 
region of the branchial siphon. 

Fig. 37, pl. ii, represents three of them from one of 
the vessels as they appear under the ;', oil immersion 
objective. These are so similar to the cells of the test 
in size, form and behavior toward stains that they need 
no description. That which has already been given ot 
the one applies in every respect to the other. 

The third point which I present in evidence for my 
contention is that I have found the cells in the process ot 
migration through the endothelium. The most convincing 


52 CALIFORNIA ACADEMY OF SCIENCES. 


instance of this is shown in fig. 30, m.c., pl. iii. Although 
neither nucleolus nor cell-body could be distinguished in 
this, still it differs in no way from many nuclei that are 
found on both sides of the membrane, 7. e., within the 
vessel and in the test. ‘That it is embedded in the pro- 
toplasmic portion of the cells of the endothelium does 
not, I think, admit of doubt. I suppose it is passing 
between the two cells, the nuclei of which lie each side 
Of iit: 

The same process of migration is seen also, I believe, 
in fig. 31. This is from a section which cuts the endo- 
thelium of a vessel tangentially, or rather at a very oblique 
angle. Onone side of the section test alone appears, 
while on the other side endothelium appears only. It 
will be seen that in the region where there is no test three 
of “these ‘nucle1, are found. Ofcourse, there is ;enear 
danger of error here, since the endothelium is very thin 
and cells on its surface on either side may easily be mis- 
taken as being situated within it. With this chance of 
error in mind, I have studied this and many other similar 
sections with care, and have convinced myself that several 
instances have been found where the migrating cells are 
in the same plane as the nuclei of the endothelial cells. 

Figure 32, pl. iii, represents an interesting condition, 
which strongly confirms the belief here maintained. The 
section is through the point at which the branchial siphon, 
already fully formed, so far as the ectodermal membrane 
is concerned, is about to break through the test. 

What is taking place will be made apparent by com- 
paring this figure with fig. 33, which represents a sim- 
ilar section of an earlier stage in the formation of the 
siphon. Shortly after the breaking through is com- 
pleted at the point of fusion of the invaginated ectoder- 
mal layer with the wall of the branchial sac, a prolific 


-PEROPHORA ANNECTENS. 53 


migration of cells takes place into the plug of test that 
fills the cavity of the ectodermal invagination. These 
cells are always strongly contrasted in their appearance 
with the ectodermal cells, and are entirely similar to cells 
of the kind already described, which are abundant in the 
blood spaces of this region. Although none of these 
cells have been found in the process of passing through 
the ectoderm at this point, it is still quite possible that 
such migrations may have been taking place without 
having been detected. All my sections that have shown 
this stage of development have been rather densely stained 
in this region. 

It is thus seen that my results add one more instance 
to the two furnished by Salensky and Kowalevsky, in 
which cells of the tunicate test are not derived from the 
ectoderm but from mesoderm, or rather in the case here 
presented, from cells derived from mesoderm; for that 
such is the origin of the original cells of the blood in 
Tunicates is well known; the source from which the 
blood cells are renewed in adult lite is, however, not so 
well known. It is quite certain, from the instances of 
division of some of them, as is shown m® fig. 36a, that 
they are the source of their own renewal—that some of 
them, at least, always retain the power of reproduction. 
All the cells of the blood are frequently spoken of by 
writers on the tunicate morphology as ‘‘ mesenchyme cells 
swimming in the blood plasma,”’ e. g., Seeliger, ’82, p. 
405. 

I must mention here that since completing these ob- 
servations on this point, I find that Kowalevsky himself 
seems to have seen the same migration of cells from the 
blood into the test in Perophora Listerz, twenty years ago. 
Thus he says: ‘‘ Souvent encore, ou peut réussir a voir 
des globules sanguins hors de la cavité des stolons, contre 


54 CALIFORNIA ACADEMY OF SCIENCES. 


les parois du corps dans le manteau extérieur; ces globules 
ont perdu en partie leurs granulations graisseuses et se 
sont transformés en cellules voyagueses, puis ont formé 
les cellules. manteau,’’ p. 6. He then says he has never 
seen the direct passage of these ‘‘ cellules amoeboides ’’ 
through the wall of the stolon. I am ata loss to know 
why Kowalevsky does not recur to this in his recent 
paper—whether he does not consider it a case in point, 
or whether he had forgotten it. 

I have never seen any indication of these cells per- 
forming a phagocytic function such as is described by 
Metschinkoft and Kowalevsky as taking place in the tests 
of other Tunicates. A considerable variety of foreign 
bodies is found on the surface and imbedded within the 
test of Perophora, but I have searched in vain for any 
signs of their being surrounded or ingested by the, test 
cells. I have thought it possible that the unusual accu- 
mulation of the cells at the point where the branchial 
opening is about to form might mean that they are in 
some way instrumental in effecting the breaking through 
of the test. Of this I have no other proof, however, than 
the mere fact of their numerous presence at this point. 

It seems to me that a sufficient number of cases suf- 
ficiently widely distributed through the Tunicata are 
now known to warrant the conclusion that a mesodermal 
origin of the cells of the test is very general in the group. 
However, with the large amount and excellent quality of 
the positive testimony that the ectoderm gives origin to 
them also, we are not justified in believing the mesoderm 
to be their only source. It is worthy of notice, though, 
that numerous writers, particularly recent ones, that 
might be cited, have simply taken for granted their ecto- 
dermal origin. 

I have no evidence that the matrix, or cellulose portion 


PEROPHORA ANNECTENS. 


OL 
Sal 


of the test is produced as a secretion of the mesodermal 
cells imbedded in it. It seems rather to be the product 
of the ectodermal cells by which it is lined; and this 
agrees with the more usual view of its origin. In many 
places, both in the stolons and in the developing zooids, 
the cells of the ectodermal layer have such a form as is 
shown in fig. 39, pl. iii. I believe this to be due to the 
fact that the cellulose substance of the test is here being 
formed. The processes are probably similar to the ones 
described by Salensky (’91, p. 14), in Pyrosoma, as like- 
wise projecting from the ectoderm cells into the test. 
This author also regards the processes as having to do 
with the formation of the cellulose substance. He says, 
however, that they are found only at an early stage in the 
development of the individual. 


3. THE MUSCULATURE. 


The musculature of the mantle is confined to the 
anterior end of the body, as in other species of the genus. 
As seen in the whole animal, when examined as a trans- 
parent object, the longitudinal fibres are most conspicuous 
as they run backward, separated by wide and quite regular 
intervals, into a region where the test is particularly thin 
and transparent. (Fig. 3, 7. m., pl. i.) As seen by this 
figure, they are radially arranged, each bundle of fibres 
growing gradually smaller as it passes backward, finally 
disappearing entirely, usually before the second transverse 
branchial vessel is reached. A small fragment of the 
mantle from the branchial siphon is shown in fig. 18, 
pl. ii. The specimen is seen upon its external surtace, 
consequently the circular fibres are generally situated 
internally to the longitudinal fibres. This, however, is 
not always the case, as for example, the radial bundle 
r. m.’ passes under some of the circular bundles and 


56 CALIFORNIA ACADEMY OF SCIENCES. 


over others, so that in part the two layers are interwoven. 
It is also an interesting fact that not infrequently fibres 
may be seen to branch off from a circular bundle and 
pass into, and become a part of a longitudinal bundle. 


4. THE PHARYNGEAL APPARATUS. 


To find some typical arrangement as to number, form 
and position of the tentacles, has been an object of much 
search, and this the more because of the unqualified 
statements on this point by Herdman (’9r) with refer- 
ence to the other species of the genus, and by Garstang 
(91); with reference to 7. Lzstevz. After examining a 
very large number of specimens, I believe the question, 
as I have treated it in the diagnosis, is as nearly definite 
as the facts will permit. In the fully compound colonies 
I have found in some individuals fourteen, in one at least 
eleven, and in another ten. As to length and distribu- 
tion, fig. 20 illustrates an average condition. There are 
almost as many different lengths as there are tentacles, 
the shortest being mere buds, while the longest are of 
considerable length. The longest are generally situated 
nearest the peripharyngeal band. 

In fig. 21, pl. ii, the tentacles of an ascidiozooid from 
one of the crowded but not compounded colonies are rep- 
resented, and the arrangement above mentioned is here 
particularly well seen. <A noticeable difference between 
the two specimens shown in these two figures is seen in 
the fact that in fig. 21 the shortest tentacles —the ones 
situated nearest the branchial orifice, are placed upon a 
low, circular ridge, a sort of velum, extending entirely 
around the orifice. This I have never seen in the fully 
compounded torms. In the crowded forms the number 
of tentacles is greater, also, by about six on an average, 
though here again I have found as many as twenty in 


PEROPHORA ANNECTENS. 57 


some specimens, and as few as sixteen in others, the 
shortest ones often being so short as to be nothing more 
than buds that can be seen only by the aid of consider- 
able magnification. It seems to me not at all impossible 
that new tentacles are constantly being formed for a long 
time after the individual animals have reached the adult 
condition. There is an evident tendency in some cases 
for the shorter and longer tentacles to alternate, though, 
as already said, the circles of shorter and probably younger 
ones are always nearer the orifice than are the circles of 
longer ones. 
@. PARASITES OF THE TENTACLES. 


At this point may be described an interesting tentaculif- 
erous infusorian that occurs parasitic on the tentacles and 
neighboring inner surface of the branchial siphon, usually 
on or near the peripharyngeal band. A group of the in- 
fested tentacles and a few of the parasites on the peri- 
pharyngeal band are shown in fig. 16, pl. 11, and a single 
tentacle is shown, more highly magnified, in fig. 17, 
pl. 11. The impression received at first sight is that one has 
before him abnormally shaped ciliated tentacles, the cilia 
being disposed in tufts. As seen by the figures, each 
tentacle is club-shaped, the terminal knob bearing a tuft 
of the coarse, usually long cilia. Besides the terminal 
knobs there are numerous others scattered irregularly on 
the sides of the tentacles, also bearing the cilia in most 
cases, though not always. As just stated, most of the 
Cilia are long. Not unfrequently, however, tufts are seen 
in which they are short and distinctly clavate (fig. 17). 
These latter are generally more numerous in each tuft 
than are the longer ones. Almost without exception the 
knobs, whether at the ends of the tentacles or on their 
sides, or on the peribranchial band, contain from one to 
several very distinct round cells, each cell having an 


55 CALIFORNIA ACADEMY OF SCIENCES. 


equally distinct, centrally situated round nucleus. The 
large knobs terminally situated on the tentacles usually 
contain more of the cells than do the lateral ones. 

That we have here one of the tentaculiferous Infusoria 
I think there can be no doubt, but I have been much 
puzzled to know what interpretation to put upon several 
appearances presented. It may be supposed that the 
cells described as being situated within the knobs are the 
anamalcules that have made their way into the tissue of 
the host, and that the knobs are produced as a patho- 
logical growth from the infected tissue. The parasite 
might then be regarded as belonging to the genus Sphe- 
rophrya of Claparede and Lachmann. However, there 
are several difficulties in the way of this view, one of 
which is, I think, fatal in itself. It will be noticed that 
the tentacles (of the parasites, for such undoubtedly are 
the structures which I have described above as ‘‘ coarse 
cilia’) are always situated, not on the cells embedded 
in the knobs, but clearly on the knobs themselves (figs. 
166) and 17. p). a1). 

The explanation that seems to me to be most in accord 
with the facts observed is that the knobs, whether ter- 
minal on the tentacles of the host or otherwise situated, 
are the foreigners, and that the contained cells described 
are endogenously produced spores. 

The terminal knobs are so perfectly continuous with 
the tentacle of the host itself that it is impossible, in any 
instances which I have seen, to fully satisfy ones self that 
the whole structure is not a tentacle. Furthermore, I am 
not able to find with certainty the nucleus in what would 
be, according to this view, the parent infusorian, though in 
the specimen shown in fig. 17 it may be present as a 
deeply stained irregular structure shown at z?. The 
cavernous spaces seen occupying the whole central por 
tion of this knob I suppose to be contractile vacuoles. 


PEROPHORA ANNECTENS. 


S 


Gt 


Another point that adds weight to the interpretation 
adopted is found in the fact that close examination does 
not discover in the knobs any of the cellular structure 
characteristic of the normal tentacle, and I believe that 
there is a thin ectosarc on the outermost surface of 
the knob; though of this I am not fully satisfied. 

This view of the matter would seem to make the or- 
ganism allied to the genus Podophrya as defined by Kent 
(’81-’82, vol. 11, pp. 806 and 813). 

However, more study of the animal will be necessary 
to fully determine its affinities. JI have not seen any liv- 
ing specimens. Only a small number of the infected 
colonies have been found, and these were all in my col- 
lection of preserved material. 


b. THE BRANCHIAL BASKET PROPER. 


As seen by fig. 3, pl. 1, the long axes of the stigmata take 
the direction of the curved antero-posterior axis of the 
branchial sac as a whole. The convergence of the circles 
of the transverse vessels on the dorsal side, already men- 
tioned, produces the effect that the stigmata are longest 
at the ventral, or endostylar side of the branchial sac, and 
become gradually shorter toward the dorsal side. 

The papillz of the transverse vessels are easily seen 
through the walls of the body when the animal is removed 
from the test and viewed by transmitted light (fig. 3 7.f.). 
There are from about six to eight’ on each half of each 
transverse vessel, making on the average about one papilla 
for each two stigmata, though the first in each row from 
the median dorsal line is removed five, or six, or more 
stigmata from this line, and are farther from this line 
than are the first ones on the ventral side from the en- 
dostyle. The middle papilla of each series.on each side 
of the body are somewhat larger than those nearer the 


60 CALIFORNIA ACADEMY OF SCIENCES. 


endostyle on the one hand or the dorsal lamina on the 
other. Figure 13, pl. ii, represents one of the papille of 
about the average size and shape. The lateral processes 
are always present, and of varying length, each one some- 
times nearly equaling half the distance between the hori- 
zontal vessels. Ihave, however, never found them con- 
nected with the corresponding processes of the adjacent 
series to form complete internal longitudinal bars, as is 
said by Garstang, 91, to be the case in some instances in 
P. Listert, and as sometimes happens, as I have observed, 
in P. viridis. There is considerable variation in the 
lengths of the middle portion (/. fig. 13) in the different 
papille. In some cases it is relatively considerably longer 
than in the specimen here figured, being nearly as long 
as the lateral processes. The papilla and their processes 
always contain a lumen continuous with that of the blood 
vessel on which they are situated, as represented in this 
figure; and the walls of the proximal, or convex sides 
of the processes, are always thickest. The cells here 
are large and round or even columnar, while those of the 
concave sides are much smaller and often flattened. The 
dorsal lamina is represented by a low ridge (fig. 21, pl. 
ii, @./.) scarcely noticeable, even on sections. The lan- 
guets, three in number, turned to the right, have been 
sufficiently mentioned above. 


Ge THE ENDOSTYLE. 


But little need be said about this organ, since it is so 
similar to what has been abundantly described for many 
other tunicates. Fig. 34, pl. ili, represents a cross sec- 
tion of it. All the parts described and figured by Fol 
(°76) for Salpa and other tunicates are here present, 
though presenting some differences in details of structure. 
These differences pertain chiefly to the two ‘‘ interme- 


PEROPHORA ANNECTENS. 61 


diary bands’”’ (m.z. 6. and 0.72. 6.) of Fol, and the cells 
carrying the long cilia at the bottom of the furrow 
(PNG ces) 

Both the intermediary bands are ciliated, though the cilia 
are quite different in the two cases, those of the outer band 
being considerably shorter and more spike-like than those 
of the middle band (vd. figure). Likewise, there is quite a 
marked difference between the cells of the two bands, asthe 
figure shows. Those of the middle band form but a single 
layer, and are cuboid, with round nuclei; while those ot 
the outer band are two or three deep, and are consider- 
ably elongated, and contain spindle-shaped nuclei. And 
further, the latter stain much more deeply than the former. 
In this respect they resemble the cells of the middle cili- 
ated band, mm. c. c., much more closely than those of the © 
inner ciliated band. The middle band is, however, but 
one cell deep, these cells being very long funnel-shaped. 
Their broad ends are directed inward, and bear the ex- 
tremely long cilia so characteristic of the tunicate endos- 
tyle. The distinctness with which these cells are stained 
by acetic acid carmine, as compared with those of the 
glandular pads on either side of them, renders them very 
striking in the sections. The glandular pads (7. 9. c., 
m. g.c. and o. g. c.) are usually considerably thicker in 
proportion to their width than in the section here figured, 
this being caused by the cells being longer, not by the 
pads being more than one cell deep. 


d. THE SUB-NEURAL GLAND. 


The duct, particularly the opening of it, differs some- 
what from that of P. Lzsterz, as described and figured by 
Garstang (’91, p. 60, and fig. 5). 

As seen by fig. 21, pl. u, d. ¢., and as already men- 
tioned in the diagnosis, the opening is not in the median 


62 CALIFORNIA ACADEMY OF SCIENCES. 


line, but is thrown off considerably to the right. (The 
figure represents the parts as seen from within the branch- 
ial basket.) It appears from Garstang’s figure that there 
may be a tendency of this kind in P. Lzsterz, but he says 
nothing about it in his description, and certainly if it were 
so strikingly true as is the case in this species, he would 
not have failed to mention it. 

There is a distinct thickening of the lip of the peri- 
pharyngeal groove in the vicinity of the opening of the 
duct, and at a high focus, when the structure is seen from 
the inside, it is found that the wall of the duct becomes 
continuous with this lip of the groove (figs. 15 and 21, 
pl) iu, ¢. 7./and Dp. 6. 2.) By the same figures itis seen 
that this thickened lp of the groove makes a U-shaped 
bend at this point, in the median line, the convexity of 
the U being directed posteriorly, or toward the ganglion. 
The mouth of the duct is always, so far as I have ob- 
served, at the right of the U. The “‘raiséd triangular 
area whose apex is posterior,’” mentioned by Garstang, 
is probably represented in my fig. 21 by the thickened 
posteriorly curved band behind the U. Although ata 
high focus the lip of the peripharyngeal groove is con- 
tinuous with the walls of the duct (fig. 15), at a deeper 
focus this continuity is lost, while the outlines of the 
mouth of the duct are still distinct, thus indicating that 
most of the orifice of the duct is dorsal to the lip. 


4- DIGESTIVE TRACT. 


Concerning the position and relations of the digestive 
tract as a whole, I have nothing to add to what is well 
known as ‘pertaining to the other species of the genus. 
In several details of structure, however, there are addi- 
tional facts that deserve to be dwelt upon somewhat. I 
have been surprised that all the published figures of this 


PEROPHORA ANNECTENS. 63 
organ fail to adequately represent the differentiation of it 
into the well-defined sections that actually exist in it. 

I had thought, before having an opportunity to examine 
any of the other species, that since none of the descriptions 
or figures of the organ under consideration show in any but 
a most indistinct and partial way several features that are 
quite obvious in this species, that perhaps a considerable 
difference existed here between this and the other species. 
As, however, I find on examining P. v7r7d7s that essentially 
the same structure here obtains, it is quite certain such is 
likewise the case throughout the genus. Fig. 9, pl. i, 
represents the digestive tract as it appears when dissected 
from the animal and examined in toto. There are five 
quite distinct regions to be recognized, instead of three, 
as described by R. Hertwig (72, p. 90), and many other 
writers, for many tunicates. Whether these all cor- 
respond, both morphologically and physiologically, to the 
five regions described by Milne-Edwards (’42, p. 275), 
in the same organ in Clavelina, I am not sure; neverthe- 
less, I use his terms to designate them. These are: @., 
cesophagus; s¢., stomach; 7z/.” duodenum : ént.’’ intest- 
ine consisting of: ch. v., the chylific vesicle, and vc., the 
rectum. 

Maurice (’88) finds five regions in the digestive tract 
of Fragroides, to which he also applies the same terms. 
The cesophagus is short and wide, and there is no valvu- 
lar constriction at its entrance into the stomach, as is the 
case in some tunicates. At the passage from the stomach 
into the duodenum there is a pronounced constriction, and 
the narrow proximal end of the duodenum is thrust into 
the much wider stomach, to which it is joined so that a 
pronounced lip, or fold is formed around the orifice. This 
structure is readily understood by reference to fig. 22, pl. 


iii, which represents a nearly longitudinal section through 


64 CALIFORNIA ACADEMY OF SCIENCES. 


this region. The index lines s¢. are directed to the lip on 
opposite sides of the orifice. The figure also shows that 
the lumen of the duodenum becomes considerably ex- 
panded immediately behind its junction with the stomach. 
But it is at the entrance of the duodenum into the chylific 
vesicle that the most pronounced valve occurs. This is 
shown in part in fig. 9, pl. i, but much better in the series 
of figs. 23, 24, 25 and 26, pl. ili, taken in serial order from 
the duodenum toward the chylific vesicle; /. d. in each 
section indicating the lumen of the duodenum. It will 
be seen that in 25 the lumen has become much narrowed, 
while in 26, where the cceca of the chylific vesicle be- 
come confluent with it, it is almost closed. These four 
sections also show well the relations of the ceeca. The 
section shown in fig. 25 is three sections—about 40 »— 
farther back than that shown in fig. 24; and the one 
shown in 26 is two sections—about 24 »—back of the one 
shown in 25. It is thus seen that they are not deep. Fig. 
26 is taken from the region where they all become con- 
fluent with the chylific vesicle, just at the entrance of the 
duodenum into this latter. 

I should call attention to the deep pits in the inner sur- 
face of the wall of the duodenum. ‘These are shown in 
figs. 23 and 24 9. cw. They are in many cases quite 
deep, and make the wall less than half its normal thick- 
ness at their bottoms; and frequently the wall bulges out 
somewhat where the pit is situated. What the significance 
of these may be I am not certain, though it seems prob- 
able that they are for the purpose of increasing the inner 
surface of this portion of the tract. Although the figures 
do not show this to be the case, it is nevertheless true that 
the perforated cuticulum, which will be described as be- 
ing present on the inner surface of the wall of the duo- 
denum, extends down into these pits. This would appear 


PEROPHORA ANNECTENS. 65 


to indicate that they have no function to perform different 
from that performed by the remaining portions of the 
epithelium. Iam also unable to determine that the cells 
are essentially different in them. : 

Histologically the digestive tract likewise presents some 
conditions of structure that are worthy of notice. The 
wall of the cesophagus is composed, as is apparently uni- 
versal in Tunicates, of very regular, columnar, ciliated 
epithelium, with a thin basement membrane on its ex- 
ternal surface. In almost all cases the inner third of the 
cells stains much more deeply than do the remaining por- 
tions. 

As we pass to the walls of the stomach, a pronounced 
change in structure is seen. The cells become much 
higher and the cilia are absent. Fig. 27, pl. iii, represents 
the typical structure in this region. As here seen, the 
wall appears to be made up of uniform, high, cylindrical 
cells, that are not in contact with one another. These 
cells stain readily in hematoxylin, carmine or cochineal, 
and each contains a distinct, round, clear nucleus, in the 
center of which is seen a single large nucleolus. The 
nuclei are situated, on an average, about one-fourth of 
the length of the cells from their outer ends, and are 
usually so great in diameter as to make them appear to 
extend entirely across the cell. I have said that the epi- 
thelium appears to be made up of these cells, which are 
not in contact. What the actual structure is, becomes 
obvious when a tangential section is examined, particu- 
larly where such a section is at the niveau of the nuclei of 
the cells described. A drawing of such a section, highly 
magnified, is shown in fig. 28, pl. iii. We here see the 
same large, clear nuclei, c. d., with a thin layer of stained 
protoplasm around them, and among these cells numer- 


ous much smaller, unstained, clear, circular areas, c. c.

These again are separated from one another by a small 
quantity of fine granular matter—intercellular substance, I 
take it to be. The bodies c. c. are probably small cells, 
since in many of them what seem to be nuclei are 
found. The large, distinct cells are undoubtedly digest- 
ive cells, since the secreted matter can often be seen 
forming globular or semi-globular masses at their 
inner extremities. They seem to be similar to the gland 
cells found in the stomach of other Tunicates (Sheldon, 
288; Roule, 35; R. Mertwio,))472,, and others) iq) tris 
possible that Roule (’85) may have seen cells similar to 
the small, clear ones described above, in Polycarpa var- 
vans. After speaking of the glandular and_ hepatic 
cellssin the stomach on this «species, the says-) “9\@er 
taines cellules méme sont entierement hyalines, et 
possédent laspect typique des cellules calicinales a 
mucus’? (p. 65). This structure of the stomach of Pero- 
phora as shown in fig. 28, pl. 11, resembles considerably 
a figure representing a surface view of the wall of one of 
the coecal appendages of the stomach of Salpa, given by 
Dolley C387, fio. 1m pl. xm): "inthe text, howeversahc 
describes the ‘‘ corsely granular pyramidal cells ’’ as be- 
ing ‘* separated from one another by lighter, finely gran- 
ular spaces, which, when viewed from the surface of the 
coecum (fig. II), present a reticulated appearance ’”’ (p. 
303). 

As seen by fig. 22, pl. iii, the lumen, which leads from 
the stomach into the duodenum, is very narrow («#’ is at 
entrance of this passage). The walls of this section are 
composed of cells of quite a different character from 
those which enter into the structure of the stomach. 
They are scarcely, if at all, granular, and their nuclei are 
generally invisible. What I suppose to be the cell bound- 
aries are very distinct, particularly in about the outer half 


PEROPHORA ANNECTENS. 67 


otethe’ walla 1! is ‘seen in ‘section’ (fig. 22 sz*., pl. i), 
giving a striated appearance to the sections. These cells 
bear short cilia, and on the inner surface of the entire 
epithelium is found a series of very regular elongated 
granules deeply stained by hematoxylin (fig. 22 c. g.) 
Whether or not these granules are produced by an artifi- 
cial breaking to pieces of a cuticular lining of the epithe- 
lium I am unable to say positively. However, from their 
constancy and regularity, and from the fact that in some 
regions their greatest length is directed at right angles to 
the surface of the epithelium, I believe the intervals be- 
tween the blocks are the expression of fine pores which 
penetrate a cuticula. I have not been able to decide 
whether the cilia are situated within or between the pores. 
This porous cuticula, if such it be, extends through the 
entire length of this portion of the intestine, even into 
the mouth of the ceca at the junction of these with the 
chylific vesicle. It does not, however, extend into the 
extremerdepths of the Cocca’ (fg. 26, pl-tmi).” 

Two kinds of cells enter into the structure of the walls 
of the ceeca themselves. The proximal portions, and a 
greater part of their extent are composed of cells quite 
similar to those found in the walls. of the duodenum. 
Their nuclei are, however, more distinct here than there 
(ips 24 25 and) 26, pl. 11). Atithe extreme: tips of the 
cceca are found a comparatively small number of cells con- 
siderably larger than those of the other portions. The 
boundaries of these are also more clearly defined, as are 


*It is possible that these structures axe similar to the enlarged portions 
of the ‘‘cordons protoplasmiques ” described by Maurice (’88, p. 168) as 
existing in the epithelium of the csophagus and rectum of Fragroides. 
However, in Perophora they are found in the duodenum and not in the 
cesophagus and rectum. Moreover, I cannot make out that they are con- 
nected with the cilia, or that there are any protoplasmic filaments running 
down into the cells from them. 


68 CALIFORNIA ACADEMY OF SCIENCES. 


also their nuclei, and the protoplasm is recognizably 
granular (fig. 26°, pl. iii g.c.) I have no sufficient reason 
either for or against the supposition that these are hepatic 
cells. They are apparently quite different from what 
have been regarded as cells of this kind in many other 
Tunicates. Maurice (’88, p. 178), considers Milne-Ed- 
wards in error in regarding the ‘‘ ventricule chylifique ”’ 
as being glandular, and he states that in Fragroides the 
epithelium lining it is the same as that lining the cesopha- 
gus. Such is certainly not the case in Perophora. The 
cells are not ciliated as in the cesophagus. They are, 
also, considerably higher here than there, and as far back 
toward the rectum as the folds which lead to the ceca 
extend, pellicles of secretive matter are abundant on their 
inner ends. It appears to me that this part of the diges- 
tive tube, including the ceca, is undoubtedly secretory, 
and that exclusively. 

The walls of the whole rectal portion of the intestine, 
including the posterior part of the region over which the 
‘‘organe refringent ’’ of Girard ramifies, is composed of 
a single layer of rather low epithelial cells which are 
ciliated, but do not have the cuticula characteristic of 
the cells of the duodenum. They are quite uniform in 
size and structure and do not appear to be secretory in 
function, excepting in a region that is transitional from 
the chylific vesicle. It seems to me probable that this is 
pre-eminently the absorptive portion of the digestive tract. 

In contradistinction to what is known to be the case in 
many other Tunicates, | am unable to find muscle fibers 
in any portion of the digestive tract. This agrees with 
Kowalevsky’s (’74, p. 17), observations on P. Lasterz. 

In his description of the ‘‘ organe réfringent”~” or 
‘* pyloric gland,’’ Chandelon (75, p. 922), says that the 
‘‘ramifications sont maintenues en place par une mem- 


PEROPHORA ANNECTENS. 69 


brane tres-délicate qui les fixe assez lachement a l’intes- 
tine.’’ And he further states that in some cases the am- 
pullz sometimes project into the blood space surround- 
ing the intestine without being at all in contact with the 
latter. I believe the structure is considerably more in- 
timately related to the intestine than the description of 
this author would lead us to understand. In sections 
through this region (which he seems not to have made), 
one sees that in general the exceedingly thin walled am- 
pullz are so closely applied to the intestinal wall that it is 
often impossible to distinguish more than one layer sep- 
arating the lumen of the ampulla from that of the in- 
testine. 


This fact may be important, it seems to me, as bearing 
on the question of the function of the organ. I have 
likewise failed to find the sudden and marked transition 
from the flat cells of the ampulle to the much higher 
cylindrical cells of the ducts, as described and figured 
by Chandelon; and I can find nothing in the structure of 
the organ to warrant the assumption that its function is 
secretory in the strict sense of the word. 

I have never found an individual in which the organ 
was wanting, as Girard (’72) states to be the case occa- 
sionally in some Tunicates, according to his observations. 


PARASITES IN THE DIGESTIVE TRACT. 


In fie. 22) pl. nina, «rand «*, I have represented some 
bodies concerning the nature of which I am in much 
doubt. That they are a stage in the life of some gre- 
garine, seems to be the most reasonable suggestion that 
I can make, and this seems the more reasonable since an 
undoubted representative of this group of protozoa is 
found in the stomach, not only of this same individual, 
but also of several others. As to what stage it represents, 


7O CALIFORNIA ACADEMY OF SCIENCES. 


or to what species it belongs, I have, however, not been 
able to gain any satisfactory clew. Lacaze-Duthiers 
(74) has described and figured several parasites found 
by him ‘ flottant dans le liquide du corps de Bojanus’”’ 
of Molgula, one of which (fig. 4) he represents as having 
irregular circular bands, apparently of some such char- 
acter as those of the bodies here described. Beyond 
this, however, there would seem to be little similarity 
between the two parasites, Some of the organisms here 
described by Lacaze-Duthiers he thinks are gregarines; 
these particular ones, however, he says, are ‘‘ evidently 
vegetable.’’ . 

As seen by the figure, the bodies which I find are quite 
large. The largest reach a length of gov. These larger 
ones are always considerably longer than broad, though 
their proportions vary considerably. Usually they are 
somewhat egg-shaped, with a slight prominence project- 
ing from the smaller end, reminding one of the epistomium 
of some of the gregarines. The smallerones are spherical, 
or very nearly so. 

Perhaps the most characteristic feature of these struc- 
tures is found in the bands, always three in number, so 
far as I have seen, by which they are girdled. These 
are made up of many elongated granules, possibly cutic- 
ular in their composition, though they seem to take stain. 
My first thought upon seeing the bodies was, that they 
were probably peritrichous infusorians that had been 
taken into the digestive tract as food; that the cilia had 
been removed by partial digestion. This might not be an 
unreasonable suggestion, but for the fact that they un- 
doubtedly bore through the wall of the digestive tube, 
and enter the surrounding blood spaces. As shown by 
the figure, some («) are wholly outside the digestive 
lumen; some («’’) are wholly within it, while others 


PEROPHORA ANNECTENS. Hf At 


again («) are buried in the wall of the organ, undoubt- 
edly on their way through. 

My reason for thinking that they pass from within out- 
wards is, that one finds, as he examines carefully the 
wall just beneath where one pierces for a little way in 
from the outside, that there is a slight break in the wall; 
whereas no such break is found when the body pierces 
part way into the wall from the inside. 

In many, though not inall, a well defined nucleus is pres- 
ent. The bands are absent from the smallest ones. I 
have found them only in the duodenum and _ chylific 
vesicle—never in the stomach itself, where the undoubted 
eregarines are found. 


©: REPRODUCTIVE SYSTEM. 


The only point in connection with the reproductive 
organs about which I need speak relates to their variabil- 
ity. Lhis applies particularly to the’ testis. Thus; in 
fourteen individuals examined in one colony, the testis 
had either one lobe, or one lobe with a trace of a second. 
In seven others of the same colony it had three lobes. 

In a second colony fourteen individuals were also ex- 
amined, and in all cases here there were many lobes, so 
many as to make it impossible to count them with certain- 
ty. Six other individuals of this same colony had a less 
number, varying from one to four. 

In twelve specimens examined from a third colony no 
trace of either testis or ovary could be found. And, it 
should be said, that this entire absence of the genital 
glands is very common in the species. Indeed, my ob- 
servations seem to indicate that it is a rule rather than an 
exception, particularly as regards the fully compounded 
colonies. I ought to mention here that none of the 
numerously lobed testes have been found in these colonies, 


72 CALIFORNIA ACADEMY OF SCIENCES. 


and this is one of the facts that leads me to think it 
possible that another species may be recognized on further 
study. Certain it is, however, that the point cannot be 
fully determined until representatives not only of numer- 
ous localities, but also of numerous ages of the colonies 
and individuals, and of different seasons of the year, 
have been carefully studied. 

Kowalevsky has stated ('74, p. 18), and his state- 
ment has been confirmed by other observers, that in P. 
Lister? the male genital products are matured before the 
female; so that the hermaphroditism is protandric. 
Whether this is true or not for this species is uncertain; 
but the facts so far observed do not seem to indicate it. 
In many cases, as e. g. the one represented in fig. 19, pl. 
11, in which both sperm and ova are well developed, I see 
no grounds for considering either as more nearly mature 
than the other. In some individuals the ovary is consid- 
erably more voluminous than the testis, while in others 
again the reverse is true. I have never seen either sperm 
or ova in the process of being discharged. 


fis CIRCULATORY SYSTEM AND BLOOD. 


The observations which I have made on this system 
that seem to add anything to what is already known from 
the study of other Tunicates, relate to the movements of 
the heart and the character of the blood cells. As is the 
case with other species of Perophora, so also in this one, 
the great transparency of the living animal makes it very 
favorable for studying the movements of the heart and 
blood streams. I find that there may be great variations 
in the number of beats ina given direction before the 
reversal takes place to the opposite direction. Thus by 
some observations made at Santa Catalina Island, during 
the past summer, it was found that in about 4,000 strokes 


PEROPHORA ANNECTENS. He 


counted in five individuals, the maximum in one direction 
without a reversal was 208 in 2 min. and g sec., while the 
minimum was 25 in I min. and 53 sec. 

In another individual examined, the examination begin- 
ning without counting, the contractions were found to 
continue in the same direction for so long a time that I 
began to wonder if this individual formed an exception 
to the rule governing the heart movements in Tunicates. 
With this I began to count, and 302 strokes in the same 
direction were performed in 7 min. before the reversal 
took place. As I am quite certain that at least an equal 
number of strokes were performed before the counting 
began, and an equal time had elapsed, it would thus fol- 
low that the strokes in the same direction without reversal 
continued 14 minutes and were about 600 in number. 
Of course, I have no means of knowing how long it may 
have been running in the same direction before my exam- 
ination began. 

From my observations, it seems quite certain that the 
total number of strokes in one direction is considerably 
greater than those in the reverse direction. 

Thus, in one individual, of the 2,392 strokes counted, 
1,485 passed from the ventral toward the dorsal side of 
the animal, and 807 in the opposite direction; and in 
every instance of reversal but three, the greater number 
was in this direction. Similar results were obtained by 
observations upon several other individuals. Whether 
the greater number of strokes is in the same direction for 
all individuals, I am not certain. 

As one watches attentively the movements of the heart, 
the impression is received that toward the close of a 
period of contraction in a given direction, the fluid has 
become condensed in the arterial vessels. A tendency 
to regurgitation is frequently noticed at such times, indi- 


74 CALIFORNIA ACADEMY OF SCIENCES. 


cating that the fluid is under pressure, Indeed, I am in- 
clined to think that such is the case; and it appears to 
me highly probable that to this is due the origin of this 
method of heart movement. We know from the studies 
of Lacaze-Duthiers, Roule, Herdman and others, on 
various groups of Tunicates, that what, for the present 
consideration at least, corresponds to a quite extensive 
system of systemic capillaries exists in many species. 
Besides, the area of surface of the containing vessels 
within the branchial apparatus must be much greater than 
that of the afferent vessels; consequently the friction 
which the moving fluid must here overcome must be cor- 
respondingly increased. 

So far as the retarding influence upon the blood of the 
capillaries is concerned, we may then regard the blood of 
Tunicates as having to be driven through two systems of 
them, i. e. a branchial and a systemic, by the same i1m- 
pulse of the heart in either direction. 

Now, it would seem that the collateral aids to the work 
of the heart, which are made use of in various ways and 
to varying degrees in most other animals in which a well- 
formed blood circulatory system is found, are very poorly, 
if at all, developed here. 

In the first place, the blood vessels, even where they 
reach their highest development are scarcely more than 
channels through the musculo-connective tissue. This 
being the case, they can have very little of the elasticity 
of vessels with true muscular walls; and this fact, taken 
together with the entire absence of valves, renders it quite 
impossible that the vessels outside the heart should exer- 
cise any power in propelling the blood through the capil- 
lary system—properly here a lacunar system. 

Concerning the structure of the vessels as they exist 
in the Cynthiade, which may be taken to represent as 


PEROPHORA ANNECTENS. WS 


high a grade of development as is found in any Tunicate, 
I may quote Roule ’85, p. 106: ‘‘ Les canaux sanguins, 
saut le cceur, n'ont pas de parois propres, isolables du 
tissu environnant; les plus simples d’entre eux ne pos- 
sedent que leur mince endothélium, et resemblent tout a 
fait aux espaces laissés, chez les animaux supérieurs, 
entre les faisceaux du tissu conjonctif; les plus complexes 
ont une enveloppe musculaire, mais les éléments de cette 
enveloppe ne lui appartiennent pas en entier, et font aussi 
partié en substratum conjonctivo-musculaire environnant. 
Le coeur seul possede des parvis propres.’’ This rudi- 
mentary condition of the vessels is still more pronounced 
in such comparatively primitive forms as Perophora, 
where even the main vessels or merely such channels, 1.e., 
the median ventral, and the median dorsal trunks, possess 
the thinnest, most imperfect kind of a wall of connect- 
ive tissue fiber and endothelium. I can detect no trace 
of muscle fibers in them. 

Considering then the tunicate blood system in the ight 
of Weber’s ‘‘ Schema of the Circulation,’’ we may fairly 
conjecture that by the retarding effect upon the blood 
stream produced by the systemic lacune and the branchial 
network of small vessels, and by the absence of elasticity 
and valves from the larger vessels, before a degree of 
pressure was reached in the arterial system sufficiently 
great to force the blood through the two connecting 
systems rapidly enough to return as much blood to the 
heart by the veins as was being forced from it into the 
arteries, a regurgitation of blood into the heart resulted 
which in some way produced a reversal in the direction 
ot the contractions. 

Since reaching this conclusion concerning the cause ot 
the reversed movements of the heart, I find that Roule 
(°85) has arrived at one apparently somewhat similar. 


76 CALIFORNIA ACADEMY OF SCIENCES. 


Thus at the close of his ‘‘ Considerations Générales ”’ 
on the circulatory system of the Cynthiadie, he says, p. 
93: ‘‘ Enfin, cette structure spéciale de l’appareil circula- 
toire a déterminé, conjointement peut-étre avec la position 
interne de l’organe de la respiration, le changement alter- 
natif du sens des courants circulatoires, afin que le sang 
artériel puisse parvenir a tour de role dans tous les organes 
(voy. mémoire, No. 40, p. 141 4 151).’’ Unfortunately 
I have been unable to consult his paper here referred to. 
The peculiar twisting of the heart during systole, such 
as has been shown by Girard (’72) and Della Valle (81), 
is represented in figure 11, pl. i. It is worthy of men- 
tion that the twist is in the same direction which ever 
direction the wave of contraction may be passing. 


THE BLOOD. 


As is apparently the rule among Tunicates, so likewise 
in this species, the cells of the blood present a great 
variety of size, form, and behavior towards reagents. 
It is exceeding difficult to decide which of these are the 
most typical and constant, or what is the relation between 
the different varieties. After considerable study it seems 
to me that four varieties may be recognized. 

One of these is represented by figures 35, 354, 354 
and 35c; a second by 36 and 36a; a third by 37, anda 
fourth by 38, pl. iii. I describe the variety shown in 36 and 
36a first, because these differ less from the typical cell 
than do any of the others—they are the least differen- 
tiated. The form is usually nearly spherical; the nu- 
cleus is large and round, contains a well defined nucle- 
olus and a very distinct nuclear membrane. The cell 
protoplasm, rather small in quantity in proportion to the 
size of the nucleus, is generally more deeply stained than 
the body of the nucleus. ‘Fhe only cases of cell division 
among the blood cells have been found in cells of this 


PEROPHORA ANNECTENS. ah 


variety. One of these is shown in fig. 36a. No metotic 
figures have been seen. 

The variety represented by figure 37 is less regular 
in form, is usually considerably smaller than the pre- 
ceding, and the cytoplasm is generally almost wholly un- 
stained, thus rendering the outlines of the cell very in- 
distinct. The nucleus is relatively considerably smaller 
than that of the preceding variety, containing less nuclear 
sap. These are the cells that are like the ones found in 
the test, hence their relations to these latter have already 
been sufficiently dwelt upon. The next kind of cells— 
or rather of bodies, for they can hardly be called cells— 
is represented by fig. 38. They are distinctly marked 
generally by their large size, their being densely stained, 
and usually, though not in all individuals, by their irreg- 
ular form giving them the appearance of having been 
greatly contracted. And this, I think, is undoubtedly 
the case since in a few specimens I have found them 
usually large and regular in outline. In the shrunken, 
deeply stained ones, no nuclei can be seen; but in the 
ones not thus shrunken and stained a relatively small, 
well stained nucleus is present. The plump ones, as 
they may be called, are very large—several times the 
volume of the largest ones of the first described variety— 
and the protoplasm has a fine granular structure. 

The fourth variety, shown in figures 35, 35a, 350 and 
35¢ seem to correspond to what are usually described in 
other Tunicates as pigment cells; though if the granules 
which are so conspicuous in them are pigment, which 
I greatly doubt, they are certainly, in this species, quite 
different from any pigment known to me; they seem to 
me to be fragments of the broken-down cell body. In 
hemytoxalin they become intensely stained, but some 
other stains, e. g., Mayer’s cochineal, attack them very 
little or not at all. lam pretty well convinced that these 


78 CALIFORNIA ACADEMY OF SCIENCES. 


are cells of the first variety breaking to pieces; they are 
worn-out blood cells. Several stages in the process are 
represented in the figures referred to. In 35, the gran- 
ules are for the most part confined to a single layer on 
the surface of the cells; many cases can be seen in which 
they are found exclusively thus disposed. In such cells 
the nucleus is still intact and distinct. The other figures 
taken in order explain the various stages of disintegration 
as I suppose it to take place. The nucleus is the last 
portion of the cell to disappear. Many of the detached 
fragments are found in some specimens scattered among 
the cells in the blood. 

I have no convincing evidence concerning the relations 
existing between the other varieties. 


Since my manuscript passed into the printer’s hands, 
ecliger’s recent paper (/93) om the origin on the )%ex 
ternal mantle ’’ of tunicates has reached me. This au- 
thor, instigated by the observations of Kowalevsky, has 
reviewed the question of the origin of the cells of the 
test with the result that Kowalevsky’s conclusions are 
fully confirmed, excepting in Appendicularia. In this 
latter group (Oikopleura cophocerca was the species 
studied) the author finds that ectodermal cells pass into 
the substance of the ‘* haus,’’ while no mesodermal cells 
were observed to do so. 

The other species studied by Seeliger were Salpa 
democratica and Claveilina lepadiformis. In both of these 
the migrating mesodermal cells are abundantly described 
and illustrated, and the ectodermal cells were not found 
to participate in the process. 

The protoplasmic processes of the ectodermal cells 
projecting into the hyaline matrix of the test are also de- 
cribed, and the author regards them as ‘‘ Sekretfaden,’ 


thus agreeing entirely, as he says, with Salensky as to 
their significance.

STUDIES IN PORTULACACEA. 
BY KATHARINE BRANDEGEE. 


Many of the plants of this order are difficult of investi- 
gation in herbarium specimens. The texture of the co- 
rolla is often so delicate that it can only be unfolded with 
considerable trouble. The frequently minute crustaceous 
seeds are equally troublesome. The slow process of 
germination can only be resorted to in a few species at 
once, and in dissection they require more than usual 
care. That they have been neglected is evidenced’by Dr. 
Gray’s remark concerning the accumbent cotyledons of 
Lewitsia rediviva, ‘‘So far as we know, it is not so in any 
other Portulacaceous plant, not even in ZL. drachycalyx.’”* 
This supposed exceptional position of the embryo is the 
character relied upon by Mr. Howell in separating the 
second species of Lewisia, and with it aggregating all 
the forms of Claytonia and Calandrinia having a circum- 
scissle capsule, under the generic name of Oreobroma.f 
The discovery of some undescribed forms in the herba- 
rium of the California Academy of Sciences having led 
to the investigation of the embryos of all the accessiblet 
genera, the results reached were somewhat unexpected, 
but sufficiently show that the position of the cotyledons is 
of no generic significance, and in those forms in which 
they are oblique (it is often impossible to be sure whether 
they are obliquely incumbent or accumbent) perhaps not 
even specific.

The circumscissile species included in the proposed 
Oreobroma show examples of all these different positions 
of the embryo. The tetrasepalous calyx, which, accord- 
ing to Dr. Gray, makes the only difference between 
Lewisia and Calandrinia, fails in the variety described 
below. Mr. Howell is, I think, quite correct in saying 
of L. brachycalyx, ‘‘sepals apparently 4,’’ for the lower 
sepals are plainly seen to be bracts, often indeed at a 
considerable distance below the others. 


LewisiA Ke_Loceir.—Caudex and fleshy root 4-5 cm. 
long: outer bracts scarious, 11%4-3 cm. long: leaves 2-3 
cm. long; petiole thick, broad and flattened, wrinkled in 
drying, narrowing upward, to the shorter obovate blade: 
peduncles stout, terete, 6-15 mm. long, jointed at the very 
base, broad at the summit: sepals 4, ovate-lanceolate, 8-10 
mm. long, glandular on the margins: petals (9 1n the only 
flower unrolled) oblanceolate, unequal in breadth, 8-12 
mm. long: stamens about 15 (too many in the figure), 
style 4-5 lobed; capsule thin, circumscissile at the base, 
splitting upward into four or five segments; seeds oblong, 
2mm. long, tuberculate in longitudinal rows, minutely 
strophiolate near the angle of the longer side; cotyledons 
oblique.—‘‘ Camp Yuba (Cisco), Sierra Nevada, Cal., 
June 27, 1870. Flowers creamy white. Granitic sand 
among rocks.’’—Dr. Albert Kellogg. 

From Z. red7viva it differs in its broad leaves, narrow 
and glandular sepals and in its peduncle jointed at the 
very base and in its oblique cotyledons. 


~The only specimen seen with ripe seeds was from New Jersey, col- 
lected by the late Harry Edwards. No fruiting specimens seen of C. Car- 


oliniana, lanceolata, umbellata ov arctica. 


STUDIES IN PORTULACACE. S9 


LEWISIA REDIVIVA, var.? YOSEMITANA.—Caudex very 
short; fleshy root very slender: leaves succulent, linear 
or spatulate, 1-2 cm. long: pedicels cylindrical, 4-1 cm. 
long, jointed just below the flower and crowned by three 
ovate scarious bracts: sepals 2, broad, concave, emarginate 
or more deeply notched at top: petals 5, about 2 cm. long, 
exceeding the sepals: stamens about 15: style rather 
shortly cleft; ovary circumscissile from a broad base; 
seeds too young for description. The flowers fall from the 
jointed pedicel, in drying, even more promptly than in 
the type.—Collected somewhere about Yosemite Valley, 
by Mrs. Willie F. Dodd, in the summer of 189I. 

This plant has so much the aspect of a depauperate 
L. rediviva that in lack of mature fruit, I prefer to de- 
scribe it as a variety of that species. Whether it prove 
to be distinct or not, it is plainly related more closely 
to L. rediviva than is any other species, and effect- 
ually breaks down the remaining barrier between Lewisia 
and the Lewisioid section of Calandrinia. There re- 
mains then only to consider whether all these species shall 
be united with Lewisia on the common characters of the 
circumscissile capsule and persistent style, or whether 
Lewisia shall be merged into Calandrinia. I think the 
first would be the more convenient. Dr. Gray says that 
circumscissile dehiscence occurs in some South Am- 
erican species of unlike habit, but does not specify which. 
There are in the herbarium of the California Academy 
about thirty species from that region, none of which 
seem to be circumscissile, though it must be confessed 
that several of them are too young to admit of certainty. 


If Montia and Claytonia are both to be maintained, 
it must be on the lines laid down by Mr. Howell—all 
3-ovuled species remanded to the first, and those with 6

ovules retained in Claytonia. The character isa shght 
one, but is assisted somewhat by the habit. 


The annual Calandrinias are probably none of them 
natives of North America. All the forms of C. Menziesi¢ 
appear to be represented by Chilian species; C. Brewer7 
is inseparable, at least in our herbarium specimens, from 
C’. compressa Schrad., and C. maritima belongs to the 
picta group, from some of which, in our herbarium, it is 
distinguished with sufficient difficulty. It often shows 
the replum-like threads separating from the margins of 
the valves so characteristic of Zalinum parvifolium. 

If Zalinum humile had been known to Fenzl his 
opinion of the relationship of Portulacacee to Ficoidez 
would have been materially strengthened. 7. Aumzle 
has a 3-celled and loculicidally dehiscent capsule, re- 
minding of Mollugo. The septa are however very thin 
and traces of similar structure in the form of central 
vertical folds on the valves are to be found in various 
species of Talinum, in Calandrinia maritima, Claytonta 
Chamissonis, Montia fontana, etc. 

It is well known that seeds are viable before maturity. 
This fact has a direct and important bearing upon the 
accurate description of the embryo. In examining a 
great number of seeds of the same species in this order, 
the principal variation was found to be in the length of 
the cotyledons. In those which had evidently reached 
a sufficient age to germinate, the embryo ranged ac- 
cording to degree of maturity, from sickle-shaped to a 
nearly complete circle, and even, in some; the tips of 
the cotyledons were hooked. In seeds having foliaceous 
cotyledons the difference between the embryos viable 
but immature, and mature seeds, is much greater. Bot- 
anists who describe the embryo from germinating seeds 
only, are therefore liable to be much misled.

SECOND REPORT ON SOME HYMENOPTERA FROM 
LOWER CALIFORNIA, MEXICO. 


BY WILLIAM Jj. FOX. 


Through the courtesy of Dr. H. W. Harkness I have 
had the opportunity of examining another collection of 
Hymenoptera made by Dr. Gustav Eisen in the Cape 
Region of Lower California. 

The collection is much larger than the one previously 
reported on, and, as may be expected, contains numer- 
ous species not before recorded from that region. Prob- 
ably the most interesting accession to the fauna of Lower 
California is the discovery of a new species of Oxea, a 
genus which has heretofore been restricted to South 
America, and to which no species has been added since 
1865, when Sichel published a monograph of the genus. 
As far as the Hymenoptera are concerned, the fauna is 
more closely related to that of the southern part of Califor- 
nia proper, Arizona and New Mexico, than it is to that of 
Mexico, and it is not until the extreme southern end of 
the peninsula is reached, which is included in the Torrid 
Zone, do the Mexican species show themselves to any ex- 
tent, and even there the Boreal forms dominate. The 
parasitic Hymenoptera will be included in another paper 
by Mr. Ashmead, as will likewise the Formicide, which 
are in the hands of Mr. Pergande for study. Unless 
otherwise stated, the specimens were collected by Mr. 
Fisen in the fall of last year.. The types’ of the new 
species described herein are in the collection of the Cali- 
fornia Academy of Sciences.

SPHAROPHTHALMA SACKENII Cress. San José del 
Cabo; October. Three 6 specimens. 


SPH4ROPTHALMA MAGNA Cress. San José del Cabo, 
October; west side of El] Taste, September; Mesa Verde, 
October. Eighteen specimens, sixteen of which are 
from the first mentioned locality, which seems to denote 
that the species is more abundant in the warmer part of 
the peninsula and that its true home is in the tropics. In 
distribution this species ranges into California and Ne- 
vada. The specimens before me show great variation in 
size, 13-25 mm. 


SPH#ROPHTHALMA GLORIOSA Sauss. San José del 
Cabo and Mesa Verde, October. Numerous specimens. 


SPH ROPHTHALMA FERRUGINEA Sm. A _ specimen 
from San José del Cabo, October, I feel obliged to refer 
to this species, although in Smith’s decription there is no 
mention made of the pale golden pubescence on second 
abdominal segment; otherwise the specimen fits the de- 
scription well. 


SPH ROPHTHALMA ZAPOTECA Bl. One specimen. San 
José del Cabo, October. 


SPH ROPHTHALMA ERECTA 0. Sp. 

? .—Ferrugineus; clothed with sparse, long, erect, 
black hair; mandibles at tip, tibia and tarsi, and apical 
margin of first and second abdominal segments slightly, 
blackish; pubescence of cheeks and abdomen beneath, 
pale; in certain lights there is seen an appressed, silvery 
pubescence on the dorsal segments of abdomen; on the 
basal portion of the second dorsal abdominal segment 
there are two longitudinally parallel, elongate, yellowish 
marks, and on the apical portion there are two similarly 
colored, semiovate spots. Head very large, much wider 


94 CALIFORNIA ACADEMY OF SCIENCES. 


than the thorax; deeply punctured, the cheeks not armed 
beneath; third joint of antenne longer than the three fol- 
lowing joints united; thorax shaped somewhat like a 
fiddle, its lateral edge crenulated; above the thorax is 
coarsely punctured, the punctures becoming gradually 
larger posteriorly until they form shallow fovez on the 
metathorax; sides of thorax glabrous; abdomen much 
more finely and closely punctured than the head and 
thorax; on the sides of the second dorsal segment and 
on the same segment ventrally the punctures are sparse; 
tibiz with strong, reddish spines, their calcaria whitish ; 
on the pleurz over the four hind coxe there is a large 
patch of silvery pile. Length, 9 mm. 

West side of El Taste, September. Is related, though 
not closely, to S. canadensts, contumax, chiapa, cruczata 
and petricola. 


SPH ROPATHALMA SCABER DN. Sp. 


2 .—Black, clothed above with dense pale ochraceous 
pubescence: cheeks, thorax on sides and beneath, abdo- 
men ventrally and the legs with a much sparser and paler 
pubescence, through which the black ground color shows 
plainly; at the base of the second dorsal abdominal seg- 
ment there is a large patch of black pubescence, the 
hinder part of which is angulated; the entire insect is 
deeply punctured, especially on the second ventral seg- 
ment, which is almost scabrous; four hind tibiz with two 
rows of strong spines; pygidial area rugose. Length 
13-14 mm. 

San José del Cabo, October. I have seen three speci- 
mens of this species, two in the present collection and 
one in the former lot. In general shape it is much like 
S. pacifica and aureola, but the head is smaller. In ap- 
pearance it resembles magna and erudita, from which it 
differs by the black spot on second segment.

96 CALIFORNIA ACADEMY OF SCIENCES. 


PARATIPHIA A2QUALIS N. sp. 

? .—Head with large, deep punctures, sparser on the 
vertex, finer and closer on the cheeks; front before the 
ocelli smooth and glabrous; clypeus rounded anteriorly ; 
flagellum stout, the first joint slightly shorter than the 
second; scape strongly punctured and bearing white hair ; 
ocelli placed in pits; prothorax above, except hind mar- 
gin, with coarse, somewhat confluent punctures; dorsulum 
with large scattered punctures, the lateral impressions 
deep; scutellum and postscutellum punctured like the 
dorsulum, the scutellum strongly impressed medially; 
metathorax above finely shagreened, and at the apex with 
some strong folds or rugz, the posterior face more strong- 
ly shagreened and indistinctly punctured; propleure 
strongly punctured, sparsely so on lower portion; meta- 
pleure with coarse striations; spines of tibia and tarsi 
reddish testaceous, the calcaria white; first and second 
dorsal abdominal segments about equally punctured, the 
second ventral a little more strongly so; the remaining 
segments more closely punctured; last dorsal segment, 
except apical portion, coarsely roughened. Black; head, 
thorax, especially on fore part of prothorax and legs, with 
pale pubescence; a fringe at apex of ventral abdominal 
and the sides of the dorsal segments of whitish hair; 
mandibles medially and tip of last dorsal abdominal seg- 
ment reddish. Length 11-12 mm. 

é .—Head rather finely punctured; antenne stout, the 
first joint of flagellum a little more than half as long as the 
second; in length the antenne reach slightly beyond the 
tegule; prothorax rather finely punctured, its lateral 
angles not acute; punctuation of dorsulum and scutel- 
lum stronger and sparser than that of the prothorax; 
upper surface of metathorax with two approximate fovee 
in the middle, on each side of these tovez the metathorax 


HYMENOPTERA FROM LOWER CALIFORNIA. 97 


is finely punctured, and just behind them, on the verge of 
the truncation, there is a transverse row of similar fovez 
extending from side to side; propleura punctured, with 
some striations on lower portion, the metapleure coarsely 
striated: the abdomen punctured similarly as in the 2 ; 
last dorsal segment strongly carinated medially. Length 
Q-II mm. 

San José del Cabo, October; El Chinche, September. 
Nine specimens. The black clypeus of ¢ and color of 
wings of ? will separate it from a/ézlabris. The wings 
of ¢ are subfuscous, with the nervures and stigma black. 
In the ¢6 they are subhyaline, with a fuscous stain at tip 
of marginal cell. The punctation of abdomen will 
separate it from Paratiphia (EH pomidiopteron ) Smithii 
Cam. 


SCOLIA BADIA Sauss. El Taste, on the west side, Sep- 
tember, and 3,400 feet. San José del Cabo, October. 
The ¢, which has hitherto been undescribed, is colored 
like the @ , except that the vertex, scape and greater part 
of dorsulum are black; sometimes the dorsulum is en- 
tirely black. 


Scotia LEconrTEI Cress. Three specimens. San José 
del Cabo, October. One specimen lacks the yellow on 
scutellum and first and second abdominal segment, and 
the yellow on pronotum is reduced to two small spots 
on anterior portion. 


SCOLIA CONSORS Sauss. One specimen. San José 
del Cabo, October. 


ScouiA Ripinesit Cress. San José del Cabo, October. 
There exists a remarkable similarity between this species 
and lis xantiana ¢. The ground color and markings 
are almost exactly the same, and ata first glance these 


species would be taken to be one and the same.

males appear to be much commoner than the females. 


Exits porRSATA Fab. (¢o/feca Sauss.) Numerous speci- 
mens. San José del Cabo, October, and El Chinche,

POMPILIDZ. 


PompPiLus #THIOPS Cress. E] Taste, 3,400 feet. One 
2 specimen. 


POMPILUS PORUS N. sp. 

? .—Clypeus rounded anteriorly; front with a faintly 
impressed line from lower ocellus to base of antenna; 
hind ocelli separated from each other by a greater dis- 
tance than they are from the nearest eye-margin; anten- 
nz slender, the first joint of the flagellum much longer 
than the second; eyes converging towards the ver- 
tex; posterior margin of prothorax arcuate; metathorax 
rounded behind, not impressed; tibia and tarsi strongly 
spinose, the fore tarsi with a well developed comb; longer 
spur of hind tibiz equal to about two-thirds the length of 
the first hind tarsal joint; abdomen a little longer than 
the head and thorax; the apical segments sparsely clothed 
with black hairs. Black; hind femora except the base, 
and the tibia reddish; anterior and posterior orbits, pos- 
terior margin of the prothorax, and a spot just before 
the scutellum pale yellowish; the whole insect is clothed 
with a sericeous pile; the face, prothorax, apex of meta- 
thorax, hind coxe and the first segment of abdomen more 
or less with silvery pubescence; wings subhyaline, their 
apices broadly fuscous, third submarginal cell much nar- 


HYMENOPTERA FROM LOWER CALIFORNIA. 99 


rowed at the top, receiving the recurrent nervure a little 
beyond the middle; the cheeks possess some long white 
hairs. Length, 9 mm. 

é .—Differs from the ¢ by the short, stout antenne, the 
first joint of flagellum being but little longer than the sec- 
ond, by the white calcaria and spines of tibiz and tarsi, 
and by having the base of the third and the last dorsal 
segment entirely, whitish; only the apical part of the hind 
femora and basal half or two-thirds of their tibia, red- 
dish. Length, 7 mm. 

San José del Cabo, October. Three specimens. Closely 
related to posterus Fox and exactus Cam. From the former 
it differs by the lesser distance between the eyes at the 
top and the narrower third submarginal cell; from the 
latter species it differs chiefly by the hind ocelli being 
more widely separated from each other than they are 
from the nearest eye-margin; and moreover the four an- 
terior lees are black. “The 61s evidently the “° small 
form ’’ mentioned by Cameron under the description of 
exactus. 


POMPILUS CORUSCUS var. JUXTA Cress. Five ? and 
3 6 specimens. San José del Cabo, October. 


POMPILUS INTERRUPTUS Say. San José Cabo, Octo- 
ber. One 4 specimen. The coloration of this speci- 
men agrees better with the description P. da/teatus Cam.., 
than zzterruptus, but the fore margin of clypeus is not 


incurved. 


POMPILUS EQUUS N. sp. 

¢ .—Bluish-black; clypeus black, planate, finely and 
sparsely punctured, subtruncate anteriorly; just above 
the base of antenne there is a short longitudinal im- 
pressed line; eyes, if anything, slightly diverge towards 
the vertex; hind ocelli separated from each other by a 


100 CALIFORNIA ACADEMY OF SCIENCES. 


distinctly shorter distance than they are from the nearest 
eye-margin; first joint of flagellum distinctly longer than. 
the second; scape shining, punctured, in length about 
equal to the pedicellum and first joint of flagellum united ; 
prothorax long, rounded at the sides anteriorly; meta- 
pleure and the lateral part of posterior face of meta- 
thorax, with coarse, transverse striations, the metanotum 
without striz and on its apical part with a medial impres- 
sion; legs darker than the thorax, tibia and tarsi toler- 
ably well spined; fore tarsi without comb, although there 
is a row of very short spines on the first joint; longer 
spur of hind tibia equalling less than one-third the length 
of the first hind tarsal joint; wings blue-black, darker at 
the apex; length of the second and third submarginal 
cells at the top about equal, second recurrent nervure 
received in the middle of the third submarginal cell; ab- 
domen half again as long as the head and thorax, com- 
pressed apically, last segment sparsely clothed with black 
hairs, Wength, 17. mm. 

El Taste, 3,400 feet. Related to macronotum Kohl and 
levifrons Cress., from both of which it differs by the 
first joint of flagellum being longer than the second; from 
telemon Cam., it differs by the smooth top of metathorax 
and by lacking the channel which connects the hind ocelhi 
with the eyes. This species probably belongs to Kohl’s 
group 18 (=Pedinaspis Kohl). 


Pompiuus sp. A 8 specimen from Todos Santos, Oc-- 
tober, that seems to represent an undescribed species. 
The head just behind the ocelli is strongly swollen, which 
gives it quite an odd appearance. 


PEPSIS TERMINATA Dhlb. (=ornata Lep.) San José 
del Cabo, October, and El Taste, 3,400 feet.) a hree 
females. 


HYMENOPTERA FROM LOWER CALIFORNIA. IOI 


PEPsIS RUBRA Drury. About forty specimens of this 
common and widely distributed species. San José del 
Cabo and Todos Santos, October. El Taste, 3,400 feet. 
The series before me shows considerable variation, some 
lack the white tip to wings, and in several males the ful- 
vous is confined to the central part of the wing. One 
specimen measures but 2I mm. 


PEPSIS HESPERLZ Patt. One 6 specimen. West side 
of El Taste. This species seems to be closely allied to 
P. Andrei Mocs., to which species I had at first referred 
the specimen. 


Myenimia sp. El] Taste, 3,400 feet. A specimen that 
differs only from wstu/atus by the distance between the 
hind ocelli and the eyes being about twice greater than 
the space between them. 


SPHECIDZ. 


AMMOPHILA QUADRIDENTATA Cam. West side of El 
Taste, September. One specimen. 


AMMOPHILA S4@VA Sm. El Taste, 3,400 feet. One 
specimen. A. strzolata Cam., seems to be very close to, 
if not identical with, this species. 


AMMOPHILA MACRA ? Cress. Three 6 specimens from 
El Taste, 3,400 feet, that differ somewhat from macra. 
They may represent the 6 of seva. 


AMMOPHILA PRUINOSA Cress. San José del Cabo, 
October. Seven specimens. 


AMMOPHILA YARROW! Cress. Numerous specimens. 
San José del Cabo, October. The ¢ is larger than the 
é , the thorax more densely pruinose, the red on legs and 
abdomen brighter and more extended. 


AMMOPHILA sp. Eight ? and nine ¢ specimens of a 
species that I cannot place. San José del Cabo, October. 


102 CALIFORNIA ACADEMY OF SCIENCES. 


AMMOPHILA FEMUR-RUBRA D0. sp. 

? .—Clypeus depressed in the middle anteriorly, with 
rather strong separated punctures on tore portion, its an- 
terior margin slightly incurved medially; front and vertex 
very finely and closely punctured, the former deeply 
channeled down the middle; vertex a little depressed on 
each side of the hind ocelli; space between the hind ocelli 
much less than the distance separating them from the 
nearest eye margin; first joint of flagellum about equal 
to the length of the two following joints united; prothorax 
and dorsulum strongly impressed down the middle, with 
a rather indistinct punctation; scutellum longitudinally 
striated on apical half, impressed; sides of metanotum 
with longitudinally oblique striations, those in the inclosed 
space transversely oblique; propleure indistinctly striated 
below; mesopleurz sparsely punctured; petiole of ab- 
domen composed of two segments. Black; abdomen, 
except spot at the base of second segment of petiole, large 
spot on third and fourth and the dorsal and ventral apical 
segments, pale red; all the femora, except a black line 
on top the anterior and posterior, also red (sometimes the 
fore tibiz and tarsired) ; front, clypeus, cheeks, tubercles, 
large elongate mark on meso- and metapleure, posterior 
face of metathorax anda spot on the median and hind 
coxe, of silvery pile; clypeus, mandibles and cheeks 
with long, sparse, pale pubescence; wings subhyaline, 
slightly darker on apical margins, second submarginal 
cell at the top wider than the second. Length 18-20 mm. 

San José del Cabo, October. Seven specimens. The 
red femora and black tibia and tarsi will distinguish this 
from any of the North American or Mexican species of 
Ammophila now known.

SPHEX PENNSYLVANICUS Linné. I refer to this species 
a 6 specimen from E] Taste, 3,400 feet, which differs 
from the typical form by being slightly stouter and by 
having the reflection of wings bluer. 

SpHEex Luca Sauss. West side of El Taste, Septem-

specimens are entirely black, except the first two or three 
abdominal segments on the extreme sides, which are ruto- 
testaceous.

should be placed in the synonomy, it is but just to give 
the credit to the latter author.

TACHYTES EXORNATUS Fox. 

Ina paper onthe North American Larride,* I described 
a new species of Zachytes from New Mexico, based on 
a @. There are before me three females from San José 
del Cabo, October, and El Taste 3,400 feet, that evidently 
belong to this species. They may be characterized as 
follows: 

@ .—Black; the legs, except coxe and trochanters, 
and the abdomen red, except a blotch on the third dorsal 
abdominal segment, the fourth and fifth dorsals entirely, 
and spots or blotches on the ventral segments, all of 
which are black; basal half of mandibles, spot at apex of 
scape beneath and the tegule, also reddish; head in front, 
dorsulum, especially on sides, mesopleure, with pale golden 
pubescence, that on the other parts of the thorax and on 
the occiput, grayish; cheeks, legs more or less and the 
apical margin of dorsal abdominal segments 1-4, with 
silvery pile, that on the pygidium golden; wings yellow- 
ish, iridescent, dusky at apex; nervures reddish testa- 
ceous. Anterior margin of clypeus somewhat rounded- 
out and armed with two teeth on each extreme side; space 
between the eyes at the top less than the length of an- 
tennal joints 2 and 3 united; first joint of flagellum scarcely 
one-quarter longer than the second; scutellum not im- 
pressed; metanotum not furrowed, the fovea at apex dis- 
tinct; tibia and tarsi strongly spinose; longer spur of 
hind tibiz slightly longer than the first joint of hind tarsi; 
ventral abdominal segments 3-6 sparsely punctured, and 
segments 2-5 with a transverse row of bristles before 
their apices. Length 18-19 mm.

APHILANTHOPS HISPIDUS N. sp. 

6 .—Black; the head, thorax, femora and first seg- 
ment of abdomen densely clothed with long, whitish hair,

strongly and sparsely punctured, with a strong, transverse 
impression before the anterior margin, which gives the 
latter the appearance of being slightly reflexed; front

appear coarsely granulated; joints 4—7 of the flagellum 
beneath, pale testaceous, the first joint distinctly longer

and that on apical margins of segments not so prominent; 
wings asin the $. Length 9-10 mm.

SOME PARASITIC HYMENOPTERA FROM LOWER 
CALIFORNIA. 


BY WILLIAM H. ASHMEAD. 


The following paper is based upon a small but inter- 
esting collection of parasitic Hymenoptera made by 
Messrs. Gustav Eisen and Charles D. Haines, in Lower 
California, Mexico, transmitted to me, to be worked up, 
by Mr. Wm. J. Fox, of the Philadelphia Academy of 
Sciences. 

The specimens collected by Haines were taken in the 
spring of 1889 and those by Eisen in the fall of 1893. 
The collection comprised in all forty-four specimens, but 
these represented twenty-one distinct species, and several, 
as was to be expected, prove new to science.

ON LAND AND FRESH WATER MOLLUSCA OF 
LOWER CALIFORNIA. No. 4. 


BY J. G. COOPER. 


A. Tare Recion Exevorep: 


In the autumn of 1893 Dr. G. Eisen made another 
collecting trip through that most tropical portion of Lower 
California lying south of the Tropic of Cancer. Having 
previously collected chiefly during the dry and colder 
months, it was intended to study the influences of the 
summer rains and heat on the animal and vegetable life 
of that region. 

His work was under the auspices of the Academy of 
Sciences, and he was accompanied by Mr. and Mrs. 
Brandegee, as botanists. 

They arrived at San José del Cabo September 5th, and 
were about two months in the field. Unfortunately, the 
season had been uncommonly dry, and there was only 
one heavy rain during their stay, about October 15th. 
The results of this dryness are apparent in the few addi- 
tions made to land mollusca; but still there were many 
interesting observations to record on new local forms from 
points not before visited, as well as one decidedly new 
species. 

An aneroid barometer was used to ascertain the approx- 
imate heights at which the specimens were collected, and 
gave elevations not far different from those marked down 
on the U. S. Coast Survey maps of the region. The 
summits of the peaks, however, were always found to be 
granitic and waterless, so that few mollusca could exist 
far above the camping grounds, where springs and alluvial 
soil caused enough vegetation to supply food and dense 
shrubby vegetation for the protection of shells from ene- 


mies or from the hot sun. 
2p S=R., Vou. IV. April 28, 1894. 


LOWER CALIFORNIAN MOLLUSCA. Wei 


The heights of camps given are not generally within 
several hundred feet of the summits, but are at the local- 
ities where shells were found living in most cases, while 
lower down there were more dead ones. As in this State, 
the occurrence of great numbers of shells on the surface, 
mostly dead, indicated that the annual production of young 
is quite limited, but that the shells have been accumulating 
for many years, while for many miles between such spots 
not one can be found. The whole collection was made 
within forty miles north of Cape St. Lucas, and some of 
the rarest of those distributed so sparingly by Xantus 
were found abundant only ten miles north of the Cape 
and a little over 2,000 feet above the sea. (Distances in 
straight lines. ) 

The following localities of camps were the most pro- 
ductive of land shells: 

I. San José del Cabo and along the little permanent 
river for twenty miles northward to Santa Anita at a 
height of 300 feet, and near thirty miles N. N. E. of the 
Cape. (This place was before estimated at only 100 feet 
elevation.) 

2. Sierra El Chinche, ‘‘Chinchbug Mountains,’’ eight 
miles north of Cape (about latitude 23°), 2,000 feet alti- 
tude. 

3. Sauzito, a few miles north and 3,200 feet high. 

4. Sierra El Taste, ‘‘ Meadow Mountains,’’ eighteen 
miles north and 4,200 feet high. 

5. Saltito, north of last and 3,200 feet high. 

6. La Chuparosa (the Humming-bird) is a camp on 
the Sierra Laguna, and is near 6,000 feet altitude instead 
of 2,000, as before printed. 

7. Sierra Laguna, about forty miles north, near the 
Tropic of Cancer, and put down by the U.S. Coast Sur- 
vey map as 5,924 feet, though Dr. Eisen’s barometer 


132 CALIFORNIA ACADEMY OF SCIENCES. 


made it 276 feet higher, and he thinks some peaks are 
over 7,000 feet. 

None of these figures indicate the highest points of the 
peaks, only the camps. 

The preceding are all along the central ridge of the 
peninsula, and the Coast Survey gives heights of two. 
somewhat parallel ridges varying from 773 feet near Todos 
Santos ‘Creek to 2,183 for the western, and 442 near 
Punta Arena to 4,419 further south on the eastern side of 
the peninsula. 

This mountainous region extends about as far north as 
south of the tropic, which thus crosses the center of it. 
There the level suddenly falls to a low plain from 75 to 
100 feet above the sea, extending clear across the penin- 
sula, so that there is lttle doubt of the former existence 
of the southern region as a tropical island, about 100 
miles long and 4o miles wide. From this isolation many 
peculiarities of the molluscan life may be expected, as 
compared with the more northern regions. 

Sierra Laguna is named from the former existence of a 
lagoon somewhere on it, which is reported to have bro- 
ken away its boundaries and become dry. There is not 
believed to be any fresh-water lagoon anywhere on this 
mountainous region south of La Paz, but some brackish 
ones exist at the mouths of creeks in the dry season. 

The only fresh-water shells found higher than Santa 
Anita were the Limnophysa, Physa and Pisidium, named 
in these Proceedings, 2d series, voli, p.r2n7, whic 
live near the springs that do not entirely dry up. The 
Pisidium may often be found where only dampness re- 
mains, and can crawl up the streams in that condition, 
or, if still drier, buries itself in the mud, perhaps for 
years, to await the next shower. 


LOWER CALIFORNIAN MOLLUSCA. 123 


B. BULIMULUS (PALLIDIOR?) VEGETUS AND ITS SUB- 
SPECIES. 


It has long been a doubtful question concerning two 
species (or forms) of this group, as to whether they were 
identical with two South American species (only differ- 
ing as varieties at most), or were radically distinct and 
autochthonous. 

The first American describers of species from the 
peninsula could find no specific differences, or else, con- 
sidering the great variations in species of this group, did 
not venture to separate them on comparison with descrip- 
tions and typical specimens, although Dr. Gould at first 
considered his B. vegetus specifically distinct from B. pal- 
fidior. Still later, Binney and Bland described the lingual 
dentition of the Peruvian B. pallidior, and had means of 
comparing that of the peninsular allied form, but did not 
report any differences between them. 

Since the expedition to the peninsula in 1891, Dr. W. H. 
Dall, to whom I sent living specimens of the so-called 
“*B. proteus Broderip’’ from the mountains, has separated 
the peninsular shell from the South American, without 
giving any but external differences. It is not strange 
that without good and numerous Peruvian and Chilian 
examples we were compelled to agree with the older 
authors in uniting them, since even Dr. Dall, with numer- 
ous specimens from both regions, has not ventured to 
distinguish the peninsular B. pallidior. Iam willing to 
agree to the distinctness of B. montezuma Dall, but for 
the sake of consistency must also contend that the other 
disputed form is also different in North and South Amer- 
ica, the most northern having already been separated as 
B. vegetus Gould. 

Still further to show the differences in the species of 
the unconnected geographical regions it may be stated 


134 CALIFORNIA ACADEMY OF SCIENCES. 


that, to some extent, there are corresponding local varia- 
tions in those otf North and South America, probably 
caused by their environments, and not proving their 
identity. This is alluded to by Dr. Dall as ‘*‘ remarkably 
similar effects produced by similar environments acting 
upon plastic forms of the same genetic history.’” This 
can hardly apply to the very different climate, vegetation, 
etc., of Costa Rica, but may account for the similarities 
in the shells of North and South America. 

In studying the variations in the forms of Bulimulus on 
the peninsula, anyone must be struck by the numerous 
characteristics of specific and even generic value which 
more or less connect them all, and yet divide them into 
groups so that they appear separable into divisions as ex- 
treme as almost one for each species. Still they are so 
linked together that similar characters of less importance 
connect shells of evidently distinct genera, and it becomes 
difficult to decide what to call specific and what generic. 
Further knowledge of the animals will probably unravel 
these difficult problems. 

But now, as we look at characters of the shell alone, 
we find it hard to separate many of the forms specifically 
because there are so many intermediate specimens. Thus 
a form from the Sierra El Taste (Meadow Mountains), 
in the central ridge north of Cape St. Lucas, has char- 
acters like these of (1) B. vegetus,. (2) B.vexcelsus. (3). 
spirifer and (4) B. montezuma (as they were first described 
in this order), and I therefore call it variety VEGEXSPIZA. 
With the whiteness of No. 1, they have the form of No. 2, 
the fold on columella of No. 3 and the cross-striation of 
No. 4. (Dall has named this BL. pallidior var. striatula. ) 

One of this form was mentioned by me as from Sierra 
Laguna, in a former article, p. 210, and Dall states that 
itis common on some of the islands. There is also in 


LOWER CALIFORNIAN MOLLUSCA. : ASiEy 


this last collection a form connecting still more closely 
the B. vegetus with B. montezuma, which may be called 
either a white variety of the last or a rough variety of the 
first, the sculpture being as strongly shown. I have had 
this lithographed from a photograph, enlarged 15 diame- 
ters. The present forms, now called species, were prob- 
ably much more closely connected when this region was 
an island. 


C. SEcTION LEPTrosyrsus Crosse & Fischer. 


These authors are followed by Dall in making this 
division of Bulimulus to include some species resembling 
B. spirifer Gabb, in having a more strongly twisted pil- 
lar in the upper part of the body-whorl, as in pl. v, fig. 4. 
Sometimes this has also a lamina more or less widely de- 
veloped, which is continued to the mouth ‘‘ as a fold or 
rounded ridge such as appears in the various species of 
subsection A.’’ Now, under B&B. suffatus Gould, Dall 
says: ‘‘In specimens which have survived a dry season 
attached to bark or stone the inside of the peristome and 
the space on the body between the two lips is often much 
thickened by a deposit of callus.”’ I have also recorded 
this thickening and abnormal development of teeth in 
some island species, but attribute it to food and other 
causes. 

I am of the opinion that the growth ot the wide lamina 
in some specimens is also an abnormal deposit, and caused, 
perhaps, by irritation of the muscles used in holding up 
the shell when attached to a vertical surface of rock or 
tree. Even the extra twist of the pillar is explainable on 
the same principle like the divergent mouth, none of these 
characters being constant. I give a view of a shell with 
this pillar twist that in everything else is a B. cuscendens, 
yet Dall would make it a ‘‘&. dryantz,”’ according to his 
theory, on account of an abnormal and perhaps a patho- 


136 CALIFORNIA ACADEMY OF SCIENCES. 


logical growth, putting it in a different section with a 
jaw-breaking name! It is a parallel to the occurrence of 
the lamina or ‘‘fulcrum’’ in some helicoid shells, devel- 
oped from some unusual condition of the animal, but not 
constant. It is true that such characters may prove use- 
ful, and therefore in time develop into generic characters, 
but in cases like this I can only believe them to be path- 
ological. 

I have examined many specimens of the zzscendens form 
without finding anything to warrant such a division of 
specimens by an internal and often hidden character, 
while they appear the same outside. Their variability is 
quite as great, if not greater, internally than externally, 
and few such variations are any more reliable as guides 
to the division into sections, genera, etc. 

Dr. Dall considers the much enlarged figures given in 
the 3d article as ‘‘ not characteristic ’’— probably because 
they are somewhat unlike specimens sent to him for the 
purpose of showing how much variation is to be expected 
in these shells. I have had figures engraved from photo- 
graphs showing extreme forms as unlike the original types 


as can be found. 


BULIMULUS MONTEZUMA Dall. 


From what has been written as to the subspecies of 
EB. vegetus, it will be evident that this must be considered 
the mountain form of the group. Numerous living shells 
were found on the El Taste Mountains. They occurred 
down to near 1,000 feet elevation, so that their range in- 
terlocks with that of B. vegetus, between that and 3,000 
feet, while the intermediate forms were found in this in- 
terval. Among these are the six which I have called var. 
vegexspiza, which unite also some of the characters of 
section Leptobyrsus, but not equally in all. From their 
central position they seem to be nearly like the original 


LOWER CALIFORNIAN MOLLUSCA. E37 


stock from which some others of this group have branched 
off, retaining some characters or acquiring others during 
their migrations. Among these are some exactly like 
Gould’s B. vegetus trom La Paz, and also some like the 
‘‘pallidior’’ form. At first I thought some of them were 
B. excelsus Gid., and perhaps B. spirifer Gabb, with a 
tooth visible in the aperture, but I could find no twisted 
pillar nor flange inside. 


BULIMULUS INSCENDENS W. G. B., and varieties. 


From El Taste Mountains Eisen sent about fifty normal 
in form, seventy-four of var. dryant7 and two of var. 
beldingz. Among them is every variety of size and 
smoothness, from a high polish to the roughness of 
B. montezuma, without any connection between these 
conditions; but Dr. Dall has named two more forms as 
var. alta Dall and var. monticola Dall, both of which I 
consider too unsettled to be of any value. Besides these, 
he has rather confused the subject by admitting my var. 
bryant? on p. 643, and then making some specimens which 
have internal laminz a good species, on p. 645, under the 
same name. 


BULIMULUS ARTEMISIA W. G. Binney. 


This is one of the extremely aberrant species which 
Dr. Dall tries to force into § Leptobyrsus on account of 
‘‘a faint elevated ridge far within the aperture.’ It 
might better rest in Peronzus until the animal is examined 
and compared with that of Columna. Dr. Eisen found 
it most abundant in the El Taste Mountains, obtaining 
about seventy between 3,400 and 4,200 feet elevation, but 
only one was fresh and seemed to contain the animal, 
though many had the curious epidermis unworn. This 
is shown in pl. vi, fig. 5, X 15 diameters, and the shell in 
pl. v, fig. 13. The specimens are all of the size of Bin- 


138 CALIFORNIA ACADEMY OF SCIENCES. 


ney’s type, but the epidermis is not pale yellow, but 
chestnut-brown when fresh. This has also a beaded ap- 
pearance, as shown enlarged in the figure. The little 
tubercles tormed about 27 revolving rows on the body- 
whorl and 8 to 18 rows on the others, except the two 
nuclear, which have the usual vertical riblets. There 
appeared to be deciduous flakes of epidermis on the 
granulations before brushing them oft. Inside of mouth 
when fresh, brown and shining, and some had a divergent 
mouth, as in B. cuscendens bryanti. In most of them the 
lips are connected by a continuous callus, and in some it 
is raised, as in Colwmna ramentosa, but less everted and 
thickened, as well as more oval in form. 

Three were tound near Cape St. Lucas, which measure 
0.86 to I inch long and 0.24 to 0.30 wide. Two of them 
are half bleached, but with some traces of epidermis on 
them, as well as sculpture. 

In form and epidermis there is thus a remarkable re- 
semblance between this shell and Columna ramentosa, es- 
pecially to the subspecies abdreviata, as is shown on 
comparing fig. 17 with fig. 8 (which is magnified twice), 
as well as in figs. 30 and 31. From these facts a genetic 
connection in the tertiary epochs can hardly be doubted, 
although their generic characters have since widely 
diverged. 


BULIMULUS XANTUsI W.G. Binney (&. gabbz C. & F.) 

The opinion I advanced as to the identity of these two 
forms is confirmed by Dr. Dall from comparing Binney’s 
type with the description and figure of Crosse & Fischer. 
As turther proof, Dr. Eisen collected forty specimens on 
the El Taste Mountains, which present characters chiefly 
of Binney’s type, but also some with variations like 
‘*B. gabbi’’ and those of the more eastern forms which 


oiven the name oft

var. /evis to this, but it is probable that fresher specimens 
will show more of the sculpture of typical xantus/. 

Of the late collection some are living, and these are 
strongly sculptured, as shown on pl. vi, fig. 29. (By an 
oversight, the revolving stria are given as vertical in this 
and in fig. 28; the lines of growth crossing them are not 
shown strongly enough.) In dead specimens the epider- 
mis and its granulations disappear from the surface of all 
these small species. In some the vertical growth-lines 
are the strongest, in others the revolving stria. 

The color of living shells is not yellow or pale brown 
and striped, as in var. /evzs, but uniform dark or chocolate 
brown. A small bleached shell from about 4,000 feet 
altitude, on El] Taste Mountains, is very thin, translucent, 
and filled with granitic gravel,which explains its depauper- 
ate condition from absence of lime in the soil. Near 
Cape St. Lucas seventeen were found, bleached and 
smooth, at 2,000 teet elevation. The El Taste specimens 
measure 0.80x0.50 inch to 0.95x0.45. The nuclear 
whorls closely resemble those of the Columna. 

Dr. Dall at first appears to have intended to make a 
new species of var. /ev7s, but without fresher specimens 
than have yet been found this would not be safe. The 
differences from the type pointed out by me in article 
No. 2, p. 213, are that the epidermis has no cross-sculp- 
ture, though entire, which is analogous to the difference 
between the mountain form, monfezuma, and its lowland 
representative, vegetus.

may have obtained it on one of the islands, but Xantus 
can scarcely have overlooked it, and Eisen informs me 
that he never was at Cape St. Lucas until 1893, and he 
got nothing like it there. The specimens found abund- 
antly at Hermosillo, Mexico, by him, which I called 
var. of B. alternatus Say, may possibly be referred to, but 
do not agree in every particular with the description. 


BULIMULUS SUFFLATUS W. G. Binney. 


Specimens of the young of this species much resemble 
B.xantusi, but have more swollen and obtuse whorls, the 
epidermis being also thinner and quite smooth, pale and 
shining. Numerous half-grown living specimens from 
El Taste Mountains, at about 3,200 feet altitude, have 
the thin alternately-striped epidermis entire, and vary 
largely in size of umbilicus. (See pl.v, fig. 11.) When 
larger, some examples are much more swollen than the 
typical B. sufflatus, and have only a few strips of epider- 
mis left, as in fig. 9. Four dead, bleached shells from 
El Chinché Mountains, at 2,000 feet altitude, approach 
nearer to large B. prlu/a, and are evidently mature, with 
thickened lips. One is figured in fig. 10, and they may be 
called var. CHINCHENSIS. The nearest to typical BL. pzlula 
is from near San José del Cabo, and shown in fig. 12. 
Figs. 15 and 16 are of shells from El] Taste Mountains, 
3,200 feet high, and bleached, which may be varieties of 
some here named, but until more perfect shells are ob- 
tained must be uncertain. 

The much larger form called by me var. 7vse/aris in 
article No. 3, p. 340, figured ‘on pl. xiv, fig; 6,15 weny 
similar to fig. 10, except in size, and approaches figs. 15 


and 16. 


CoLUMNA (RAMENTOSA?) ABBREVIATA J. G.C. 


Only four examples of this form were found on the El 


LOWER CALIFORNIAN MOLLUSCA. I4 1 


Taste Mountains, at about 4,200 feet, two more slender 
than the rest. Only one is fresh, and was probably alive 
when found. Both forms are represented double the 
natural size in pl. vi, figs. 18, 19, to show the extremes 
more ‘‘ characteristically ’’ than the former figures. The 
whorls in abbreviata vary from 8 to 9%. Fig. 31 shows 
how the sculpture on 3 whorls resembles that of B. arte- 
musta, and under that species I have noted the remarkable 
similarity in the form of the shells, which extends to that 
of the nuclear whorls also. 


MELANIELLA TASTENSIS n.sp. Plate vi, fig. 21. 


Shell dextral, much elongated, white, translucent,nuclear 
whorls as in JV. ezsenzana, third less narrowed, sculpture 
nearly similar, whorls 14 to 16, longer and less oblique, 
14 of them equaling 16 in that species. Outline of whorls 
flatter, mouth vertically longer, body-whorl not contracted, 
peristome not continuous, the lips being separated by the 
parietal wall about , of an inch. Whole shell a fifth 
longer, with the same number of whorls. 

Length 0.74 inch, breadth 0.08; mouth 0.10 long, 0.06 
wide.* 

Six only were found at Saltito Pass, just north of El 
Taste Mountains, at 3,200 feet altitude. In some the 
upper 6 or 7 whorls are much slenderer, proportionately, 
than the rest, as if they were starved when young, and 
often bent out of the straight course, as shown in figure. 

Found under damp wood on the ground at the end of 
the wet (summer) season. Only two of them have 16 
whorls, one 13, and three 11, these being immature. 

Fig. 21 represents this species, and fig. 20 is JZ. ezsen- 
‘ana, given for comparison, both double the natural size. 
The figures of the latter, much enlarged, in vol. 111, 2d se- 
ries, pl. xiii, give fuller details of form. 


*The breadth given for JZ. edsenzana as 0.14 is an error for 0.08. 


142 CALIFORNIA ACADEMY OF SCIENCES. 


PATULA HORNI? Gabb. 

One perfect specimen was found in Saltito Pass, 3,200 
feet, measuring 0.15 inch wide; color dark brown. I 
supposed it might be a large H/yalina diegoensis Hemp- 
hill, until I detected the scattered bristles and coarser 
opaque shell. It is new to the peninsula, having been 
found only in southern Arizona before. Unfortunately, 
it was crushed by accident. Another, bleached and im- 
mature, occurred in a dead shell of Bulimulus. 

HYALINIA INDENTATA Say. 

A few were also found on El Taste Mountains. 

PLANORBIS (ANISUS) ANITENSIS J. G. Cooper. 

About twenty specimens from Santa Anita (the only 
known locality) show a larger development of halt a 
whorl more, measuring 0.30 inch wide. They are figured 
double natural size on pl. vi, figs. 22, 23. 

The compressed sub-marginal line on right side is so 
faint in small ones that it was overlooked in the tormer 
figure, though described. In the new specimens there 
are also numerous more delicate revolving striz, the outer 
whorl being also less flattened toward the mouth. The 
sinistral appearance both in this and P. penznsularts is 
not in the outline or form of mouth, but in the flattening 
of the left side.* 

PLANORBIS PENINSULARIS J. G. C. 

About fifty more were brought from the same pond, 
and nowhere else. The description is correct without the 
(2), but the shell is a Nautilina (or Gyraulus) rather than 
Anisus. In very young of this and of the preceding the 
shell is often white and translucent. Figs. 24 and 25 
represent this species double the natural size. See, also, 
the enlarged figures in vol. iii, pl. xiv. 


* The figure of this species (8a) as given in pl. xiv, vol. iii, has a defect in 
the angular form of the right margin, caused by a fracture, but it must be easily 
detected as an error on comparison with 8b.

DESCRIPTION OF A NEW SPECIES OF RIBBON FISH, 
TRACHYPTERUS REX-SALMONORUM, FROM 
SAN FRANCISCO. 


BY DAVID S. JORDAN AND CHARLES H. GILBERT. 


Trachypterus rex-salmonorum, species nova. Plate ix. 
—Trachypterus altivelis Jordan and Gilbert, Proc. U. 8S. Nat. Mus., 
1881, 52; and Synopsis Fishes of North America, 1882, 618; not 

of Kner. 

Head 84 in length; cross depth at nape 8. Dorsal 
rays, V—170; caudal rays 8; ventral rays 6; pectoral 
11. Total length of specimen, with caudal, 17 inches. 

Body long and slender, closely compressed and ribbon- 
shaped, as usual in the genus. Head short, deeper than 
long, the anterior profile steep and nearly straight to the 
base of the nuchal crest; dorsal fin beginning on the 
top of the nuchal crest, which is directly over the second 
third of the diameter of the eye; height of crest slightly 
more than diameter of eye, the latter greater than length 
of snout and % length of head. Mouth oblique; mavxil- 
lary rugose and very broad, its width % its length; 
length of lower jaw greater than length of snout, 23 
in head, its angle under the front of the orbit. Oper- 
cular bones rugose, entirely covering the gills. Pre- 
maxillary covered with minute and feeble teeth, in ad- 
dition to which in this specimen are three canines, two on 
one side and one on the other, directed very obliquely 
backwards. On the side having two canines, one ‘is 
placed directly behind the other. Lower jaw with three 
strong canines on one side and two strong and one weak 
canine on the other, all directed obliquely backwards and 
inwards. 

Dorsal fins slightly connected at base: the filamentous 


rays of the first dorsal not quite twice the length of the

head; ventrals inserted just below axil of pectorals, 
filamentous, about half longer than head; pectorals % 
longer than eye; caudal rays simple to near tip, where is 
sometimes a single fork, the longest filamentous rays about 
three times length of head. Dorsal fin much lower than 
the body, the longest rays of the second dorsal nearly % 
length of head; a series of spinules along the base of the 
dorsal, one pair for each ray. 

Lateral line well developed, with a series of small in- 
conspicuous plates, each of which has a minute central 
prickle. Lower part of the body thickly beset with 
small spinous tubercles; rest of the skin naked: rays ot 
all the fins accompanied by a series of small prickles. 

Coloration everywhere bright metallic silvery, an ob- 
long jet black blotch a little longer than the eye lying 
close along the base of the dorsal and beginning 1% di- 
ameters of the eye behind the eye; three larger spots 
dusky but not black lying behind this along the side be- 
tween the lateral line and the dorsal fin; two smaller 
dusky spots on the belly, the one just behind the base of 
the ventrals, the other under the second of the four spots 
of the back. These spots, except the first one mention- 
ed, are all diffuse and are a little less than twice the di- 
ameter of the eye in length and about twice as long as 
deep. Anterior profile below crest, including front of 
snout and tip of mandible, jet black. Caudal and ven- 
tral fins carmine red in life; other fins unmarked. 

This species bears some resemblance to Trachypterus 
altrvelis described by Kner from Valparaiso. The latter 
species has, however, the nuchal crest much lower and 
farther back, the first dorsal and the ventrals much low- 
er, the second dorsal fin higher, the skin rougher, the 
four black spots different in size and position trom those 


found in our specimen, and the caudal rays divided near

the base.) It is. probable that the three specimens mer 
Trachypterus mentioned by us in the Synopsis of the 
Fishes of North America, page 619, and referred with 
doubt to 7rachypterus altivelis, really belong to the pres- 
ent species. One of these specimens was taken at Santa 
Cruz, Cal -by Dr.C. lL. Anderson, :and presentedmra 
the United States National Museum; the other two were 
obtained in the Straits of Fuca by Mr. J. G. Swan, and 
were not preserved. According to Mr. Swan the spe- 
cies is known by the Makah Indians west of the Straits 
of Fuca as ‘‘ King of the Salmon,’’ and its destruction is 
believed to have a baneful influence on the salmon fish- 
ing. 

The type of the present description was obtained by a 
fisherman in the open sea outside the bay of San Fran- 
cisco. It is preserved in the museum of the Leland 
Stanford Jr. University, on the register of which it is 
numbered 1382. The specimen is in perfect condition.

DESCRIPTION OF A LITTLE KNOWN AGONOID FISH, 
HIPPOCEPHALUS JAPONICUS. 


With Plate xX. 
BY FRANK CRAMER. 


But two specimens of this little known species seem to 
have been previously recorded: one, picked up by Stel- 
ler on the shore of one of the Kurile Islands in June, 
1743; the second, secured by Tilesius in the Gulf of Pa- 
tience, Island of Segalien, July 30, 1805. Steller’s spec- 
imen, preserved in a dried condition, was forwarded to 
St. Petersburg to become the type of Pallas’ Cottus ja- 
ponicus. ‘The second specimen, at first considered iden- 
tical with Coftus japonicus, was afterwards separately de- 
scribed by Tilesius under the name A gonus stegophthal- 
mus. Of the latter, Tilesius has left several descriptions 
and figures (see synonymy) which are unfortunately dis- 
cordant in many of their details. 

Subsequent writers have added little to the history of 
the species. The types of japonicus and stegophthalmus 
seem not to have been re-examined or compared, but Cu- 
vier and Valenciennes, after a careful review of the pub- 
lished figures and descriptions, decided that stegophthalmus 
and japonicus were identical, and needlessly proposed for 
the species a new name, swperciliosus. In 1839, Aspidopho- 
rus superciliosus, Aspidophorus quadricornis and A gonus 
decagonus were ranged by Swainson in a new genus, for 
which he proposed the name //zppocephalus. Needless 
to say, his generic characterization is worthless, and the 
three species therein included are not congeneric, deca- 
gonus belonging in fact in an entirely different part ot 
the family. As the species swpercrlrosus (= japonicus) is 
mentioned by Swainson first, it has been customary to 
consider it the type of the genus. Characterizations of

the latter, based on current descriptions, have been at- 
tempted by Gill, and by Jordan and Gilbert. 

A fine alcoholic specimen of this species is in the pos- 
session of the California Academy of Sciences, to which it 
was presented about 1882 by Dr. Krause of Berlin, Ger- 
many. This has been kindly loaned to the writer, and 
on it are based the following figures and descriptions. 
The specimen is 360 mm. long, and was obtained in the 
Okhotsk Sea. 


[Hippocephalus japonicus is most Closely related to A gon- 


omalus proboscidalis and Hypsagonus guadricornis. ‘These 
three species are confined to the shores of the North Pa- 
cific Ocean and differ much more trom the other mem- 
bers of the family than they do from each other. The 
group is distinguished by having the body compressed, 
the back elevated behind the nape, two rows of strong 
spines along each side of body, the spinous dorsal begin- 
ning immediately behind the nape with its spines strong 
and rough, the mouth terminal, and the branchiostegal 
membranes broadly united and free from the isthmus. 
The genus //7ppocephalus may be defined as fol- 
lows: Body moderately elongate, compressed, the back 
elevated behind nape; two rows of strong spines along 
each side of body: spinous dorsal beginning immediately 
behind nape, the spines strong and rough; head depressed; 
gill- membranes free from the isthmus; mouth terminal; 
teeth present on jaws and vomer, none on palatines; no 
barbel at tip of snout; no occipital spines; the two dor- 


sals well separated.

Description—The total length is 14% inches. The 
body is compressed throughout, but the shoulder girdles 
are prominent, so that the width of the body at the base 
of the pectorals is a little more than the greatest height, 
and 5 in body length. Immediately behind the pecto- 
rals the width isa little less than the greatest height: 
between dorsals and on peduncle it is nearly two, and 
under second dorsal a little more than two in the height 
at the same points. Abdomen moderately swollen in front 
of vent. The back rises at an angle of 45° behind the 
occiput, slopes downward under first dorsal, leaving a 
hump under its front end, rises in front of second dorsal 
and slopes downward again under it. Ventral outline 
nearly straight. 

The breast and the area between ventrals and vent are 
almost completely occupied by nearly flat, radially striated 
plates with slightly raised centers and of variable size, with 
innumerable excessively minute plates scattered among 
them. Vent surrounded by prickles. The plates of the 
ventro-lateral series are small, beginning as distinct rows 
of spinous plates about opposite vent, with an imperfect 
row of smaller spinous plates between them and the vent 
on each side, and converging toward the anal. They 
pass along sides of anal, remain distinct to about the 
eighth pair of plates behind the anal and unite in a single 
median plate with a double spine; from this plate to the 
caudal the rows are again distinct, the plates alternating 
instead of standing opposite each other. The inferior 
and superior lateral series begin as distinct rows of spin- 
ous plates about opposite the middle of the spinous dor- 
sal, diverge to about the front of the second dorsal and 
converge toward the base of the caudal; the plates are 
elongated vertically, their spines, rising abruptly from their 
centers, are strong, thick, blunt, curved. There are about 


HIPPOCEPHALUS JAPONICUS. Ssh 


37 plates in the inferior and 35 in the superior longitudinal 
row. Between them lies the median lateral series, bear- 
ing the lateral line, a nearly continuous row of 38-39 
spineless plates extending from head to base of caudal (a 
few of them with small blunt tubercles). The dorso- 
lateral series is composed of small indistinct plates from 
occiput to beyond middle of first dorsal, where they be- 
come larger and spinous. The plates of the sixth, sev- 
enth, eighth and ninth pairs behind the last ray of second 
dorsal are closely approximated, but do not form single 
median plates; from the ninth pair to the caudal the plates 
of the two rows alternate, as on the ventral surface. 
There are almost complete series of small plates, alter- 
nating with the large ones, between the dorso- and superior 
lateral series, between the superior and median lateral, 
between the median and inferior lateral and between the 
inferior and ventro-lateral series. This multiplication by 
intercalation of small plates is evident all over the body. 
There are no large but numerous minute plates in front 
of and on base of pectorals. Gill-membranes posteriorly 
and medially with several rather weak plates and many 
minute plates and prickles, anteriorly and laterally with a 
few small plates; under side of lower jaw with many im- 
pertect plates or strong prickles; weaker prickles along 
the branchiostegal rays. 

Head depressed throughout, narrow to the posterior 
border of the orbits, behind which it widens rapidly. 
Depth behind orbits 7 and over opercles % of the width at 
the same points. Orbits large, oval, 4% in head, far for- 
ward. Interorbital space a little concave, very broad; at 
anterior border of orbits wider than the orbit itself, 31% 
in head, at posterior border of orbit 2% in head. Su- 
praorbital ridges expanded into a flat triangular shelf 
projecting upward and outward over eye and ending 


152 CALIFORNIA ACADEMY OF SCIENCES. 


bluntly. Occipital ridges heavy, low, spineless, forming 
low domes behind. The space between them concave. 
Preorbital with about two ridges radiating from the an- 
terior border of orbit, each ending in a short, broad, 
plate-like, blunt spine. Suborbital with a broad dome- 
like tubercle. Preopercle with a dorso-ventrally com- 
pressed spine; below this 3 successively smaller blunt 
spines. Cheeks below orbit and suborbital with 4 or 5 
fairly developed and many minute plates. Nasal spines 
far apart, near tip of snout, sharp, nearly upright. 

A large membranous nasal tube. A _ short, flap-like 
barbel at tip of each maxillary. Mucous pores of lower 
jaw with flap-like borders. Mouth small, terminal; maxil- 
lary reaching a little beyond front of orbit. Angle of 
jaw, prominent, tubercular. 

The dorsals are tar apart, the first a short distance be- 
hind occiput; its spines very rough (like the rays of all

COAST RANGE OF CENTRAL CALIFORNIA. 


BY W. Wie PRICE. 


Neotoma californica sp. nov. Plate xi. 

Type No. 335, 6 ad., Museum of the Leland Stanford 
Junior University. From Bear Valley, San Benito 
County, California, Aipril 2, 1893. ~ Collected by. Ga 
Gilbert and W. W. Price. 

General Characters.—Closely related to WV. mexicana, 
from which it differs in its darker, less fulvous coloration, 
its longer ears, and the cranial characters as given below. 
Tail densely haired, concealing the annuli, sharply bi- 
colored. Ears very large. Throat ashy gray, the white 
confined to tip of hairs. Upper surface of feet pure 
white. 

Measurements (taken in the flesh).—Total length, 336: 
tail vertebra, 160; hind foot, 35; ear from ‘crown, 34. 
ear from notch (dry skin), 2 

Color.—Upper parts yellowish-brown, darker on middle 
of back, becoming lighter but not brighter on the flanks, 
and with little or no fulvous wash. Under parts grayish- 
white, the hairs everywhere plumbeous at base, with the 
exception of two broad patches between fore and hind 
legs and a connecting line along middle of belly, in which 
the hairs are white to the base. The ashy-white extends 
well up on the flanks, and on snout to the base of the 
whiskers. The yellowish-brown of the upper parts ex- 
tends low on sides of head, and crosses the breast in a 
faint line in front of the fore legs. It passes down the 
upper surfaces of the legs to wrist and ankle, where it 
stops abruptly, leaving the upper surfaces of the feet 
pure white. Tail bicolored, white below and on sides, 
blackish above, darker toward the tip. Ears dusky,

scantily clothed with appressed whitish hairs. In color- 
ation this species differs from JV. mexicana in having the 
purely white patches on the under side larger, the dusky 
element in the dorsal coloration more extensive, and the 
lighter element light yellow or buff, instead of deep ful- 
vous or tawny. 

Cranial characters.—In its cranial characters this spe- 
cies very closely resembles V. mexécana, with which it 
agrees in the broadly-rounded temporal region, the weak- 
ly-marked temporal ridges, the short, deep snout, with 
the nasal bones anteriorly produced and overlapping, and 
the very small auditory bulla. The two agree also in 
shape of mandible, having a very slender, backwardly- 
curved coronoid process, and a narrow, acute-angled 
postcoronoid notch. 

They differ in the following respects: 

In californica the nasal processes of premaxillaries ex- 
tend posteriorly to well beyond the nasal bones, while in 
mexicana they terminate evenly, or nearly so. 

In californica the interparietal is longer (antero- 
posteriorly) in proportion to its width, with a strong 
posterior angle. In mexicana the posterior edge is evenly 
rounded, or nearly straight, without well-defined angle. 

In calefornica the incisive foramina are short, 8.5 mm. 
in length. In mextcana they are unusually long, from ro 
mm. to II mm. in specimens of equal size with the 
former.

In No. 1207, a specimen of JV. mexzicana,* from the 
Huachuca Mountains, Arizona, in which the basilar 
length is 36 mm., the measurements agree very exactly 
with the above, except in the longer nasals (18.5 mm.), 
the longer rostrum (11 mm.), the longer incisive foramen 
(10.5 mm.), and the distance separating latter from in- 
cisors (3 mm.). 

The type specimen is adult, with the crowns of the 
molars ground down almost to the base of the plications. 

Six specimens, besides the type, are in the University 
Museum, two from the same locality as the type, Bear 
Valley, San Benito County, and four collected by W. W. 
Price, on Mt. Hamilton, Santa Clara County, November 
21 and 22, 1892. It is believed that all the specimens 
thus far obtained were living among rocks.

Neotoma albigula sp. nov. Plate xii. 

Type No. 1336, 2? ad., Museum of Leland Stanford 
Junior University. From the vicinity of Ft. Lowell, 
Arizona. Collected June 14, 1893, by W. W. Price and 
R. L. Wilbur. 

General characters.—In size very similar to Meotoma 
mexicana. ‘Tail densely haired, sharply bicolored; upper 
surface of feet pure white; throat, chest, middle line of 
belly and region between the hind legs pure white to the 
base of the hairs; other underparts grayish, the hairs 
white at tip and plumbeous at base. 

Measurements (taken in the flesh).—Total length, 322; 
tail vertebre, 158; hind foot, 32; ear (from crown), 26. 

Color.—Upper parts pale yellowish-brown, much lined 
with black and with black-tipped hairs. On the sides the 
darker shades gradually disappear, leaving an almost pure 
light yellowish area along the line of separation from the 
white of the underparts; this yellowish streak is brightest 
on the flanks and in front of the shoulders. throat: 
chest, median line of belly and patch between hind legs 
pure white, the color extending to the base of the hairs. 
The white area of the chest is continued out along the 
inner side of the fore legs. The other underparts are 
grayish-white in appearance, the hairs being broadly 
white at tip and dark plumbeous at base. The hind legs 
appear darker, owing to the narrowing of the white tips 
of the hairs. The yellowish-brown of the upper parts 
extends down on the outer side of the legs, stopping ab- 
ruptly at the wrist and ankle, leaving the feet pure white. 
Ears clothed with brown and grayish hairs: whiskers

mixed black and white, reaching to the shoulders; tail 
white below and on sides, the dark brown dorsal streak 
covering about one-third of its circumference. 

Cranial characters.—Posterior process of the intermax- 
illaries extending well beyond the nasal bones, reaching 
to opposite the posterior part of the anterior upper molar; 
interparietal wide and not very long, with an evident 
posterior angle. Compared with JV. mex7cana and JV. cal- 
?fornica, the cranium is at once conspicuous by its much 
more inflated auditory bulla. It has also a deeper snout, 
less projecting nasal bones, and deeper post-palatine 
notch. It agrees with ca/zfornica in the characters sep- 
arating the latter from mex7cana,, having short incisive 
foramina, backwardly-produced nasal processes of the 
intermaxillaries, and a decided posterior angle to the in- 
terparietal. The mandible is heavier and more strongly 
ridged than in either of the species just mentioned; the 
coronoid and condyloid processes are shorter and thicker, 
the latter hardly extending above the former, and the in- 
cluded notch is broadly rounded. 

Cranial measurements of type, No. 1336. 

Basilar length of Hensel, 36 mm. 

Greatest zygomatic breadth, 22.5 mm. 

Least interorbital width, 5. mm. 

Length of nasals, 17. mm. 

Distance from incisors to incisive foramina, 3.5 mm. 
Length of incisive foramina, 8.3 mm. 

Length of rostrum from front of zygoma, II. mm. 
Height of rostrum at front of zygoma, 9. mm. 

Neotoma albigula agrees in size and general propor- 
tions with Veofoma mexicana, but differs in the following 
respects:

FORMICIDA OF LOWER CALIFORNIA, MEXICO. 


BY THEO. PERGANDE. 


Since the publication of my paper, published in these 
Proceedings (pp. 26-36, ante), I have again received, 
through Mr. W. J. Fox of Philadelphia, another small 
collection of ants from Lower California, collected by 
Dr. Gustav Eisen, among which are some species not 
previously recorded from the peninsula of Lower Cal- 
ifornia, and also several new forms, which will herewith 
be described. I hardly need to say that our knowledge 
of the Formicide of Lower California is still very limited, 
and that the material now available for study represents 
but a small fraction of the genera and species actually 
occurring in that interesting region. 


FORMICID. 


i, C©AMPONOTUS SAYI Emery, subsp. BICOLOR, \n.- 
subsp. 

6 major:. Length, 9-10 mm. .-blead, 2.8%2.6; “scape, 
gimims Post. fem.,-2.0 mim. 

Almost identical with the typical form, though larger 
and more robust. ‘The head is somewhat longer and its 
posterior margin more deeply concave; the surface more 
highly polished; eyes smaller; anterior emargination 
of the clypeus broader and more distinct. Mandibles 
smoother, rather more highly polished, not striated or 
but very feebly so, and with fewer punctures. The su- 
tures between thoracic segments are deeper, especially 
that between the meso- and metanotum: the mesonotum 
more elevated. 

Colorotion as in sayz, though the head somewhat dark- 
enmred. 

% minor: Length, 3-7 mm. The head of this form 


is much narrower than in the 8 major, particularly pos- 
2p SER,, Vou. IV, (aul) May 17, 1894.

teriorly, and comparatively longer than in sayz; the eyes 
are also smaller and less strongly projecting; the protho- 
rax more flattened above, its sutures deepey, and the scale 
narrower and stouter. It differs from sayz also consider- 
ably in the coloration of the head, thorax and scale, par- 
ticularly in the smaller specimens. 

Head black; the clypeus, cheeks and space in front of 
eyes red; the meso- and metanotum above, the upper an- 
gle of the metathoracic declivity and the scale black or 
dark brown. Otherwise as in Camp. sayz. 

®. Length, 11 mm:; expanse-of wings, .24 mm. 

The head is either red, with only the posterior edge of 
the vertex more or less distinctly dusky, or of the same 
coloration as in the worker minor. Thorax highly pol- 
ished, red; posterior edge of pronotum above, a large 
median spot anteriorly and a subdorsal vitta each side of 
mesonotum, scutellum, mesosternal plate and abdomen 
black. Legs and scale red. Posterior margin of ab- 
~dominal segments yellowish. Wings pale brownish, veins 
and stigma darker. 

6. Length,6-7 mm. Entirely black, polished. Pos- 
terior margin of abdominal segments, extreme tip and 
genital valves yellowish-white; the inner pair of valves 
gradually brownish towards the end, the apex of the up- 
per pair blackish. 

Described from many workers, two females and three 
males.

%. Length, 4-5 mm. Head elongate, longer than 
broad, rounded behind. Face and clypeus densely and 
finely striated, the striz coarser and less dense posterior- 
ly, the vertex almost smooth. Frontal area with a me- 
dian carina. Mandibles longitudinally striated and with 
a few coarse punctures near the terminal edge. Protho- 
rax with extremely fine striz at the sides anteriorly. Me- 
sothorax smooth. Metathorax with fine, transverse striz 
above, the striz longitudinal and coarser laterally at pos- 
terior half. Metathoracic spines wanting, their position

represented by minute, toothlike projections at the termi- 
nation of the metathoracic ridges. Nodes of petiole erect, 
the posterior one stoutest. Head, thorax and abdomen 
furnished with rather sparsely set, fine, erect, yellowish 
hairs; those of the antenne and legs shorter and less 
erect: 

Color black, polished. Mandibles, flagellum and tarsi 
reddish-brown; the flagellum darkest towards base, with 
the apex of the joints blackish. Scape and legs dark 
brown. 

This species may be easily mistaken for APA. Pergan- 
de?, with which it agrees in size and coloration, but may 
be readily distinguished from it by the striated head and 
metathorax, the absence of metathoracic spines and the 
much higher second: node of the petiolus. 

Described from eight specimens. 

Sierra Laguna and El Chinche. 


6. APHANOGASTER JULIANA DN. Sp. 

Length, 5-7mm. Head quadrangular, somewhat longer 
than wide; its sides almost straight, faintly broader be- 
hind; posterior angles rounded. Surface polished, with 
fine and dense stri#, somewhat coarser in front of eyes 
and slightly diverging posteriorly; stria of vertex trans- 
verse. Spaces between the striz, with few, scattered, 
shallow punctures. 

Mandibles stout, similar to those of Pogonomyrmex, 
with two prominent teeth at apex and three to four rudi- 
mentary teeth; the surface coarsely striated. 

Prothorax transversely rugose, with the space between 
the ruge granulated; meso- and metathorax longitudi- 
nally rugose and densely granulated between the ruge at 
the sides of the metathorax. Spines of metathorax large 
and diverging posteriorly; the space between the spines 
finely granulated; the posterior declivity smooth. 


FORMICIDZA FROM LOWER CALIFORNIA. 165 


First node of the petiole large, its sides parallel, stout- 
est at base, the apex rounded gently curved forward and 
with two longitudinal impressions. Second node broad- 
ly pyriform, stoutest posteriorly, and also with two long- 
itudinal impressions above. Both joints are highly pol- 
ished and minutely granulated. 

Abdomen polished, finely shagreened and sparsely 
punctured. MHairs yellowish and rather sparse, more 
dense along posterior margin of abdominal segments; 
those of the anterior margin of the clypeus are longer 
and stouter, while those on the under side of the head are 
very long, slender and curved forward. Hairs of antenne 
and legs shortest and semi-erect. 

Color dark brown, almost black, the thorax somewhat 
lighter. Antenna, mandibles and legs reddish-brown. 

This species resembles very much APA. Andrez, which 
differs from it, however, in the much coarser sculpture 
of the head and thorax, in the stronger constriction be- 
tween the meso- and metathorax, the stouter and less 
strongly curved first node of the petiolus, in the rougher 
sculpture of both nodes and in the very profuse, brist- 
ling, white and glittering hairs, which are most conspic- 
uous on the abdomen and legs. 

Described from seven specimens.

ON SOME PLIOCENE FRESH WATER FOSSILS OF 
CALIFORNIA. 


BY. J. G. COOPER. 


MARGARITANA SUBANGULATA n. sp. Plate xiv, figs. 
I-4. 

In form nearly intermediate between J7. margaritifera 
Linné and J/. marginata Say, beaks more prominent 
and anterior than in the former, less so than in the latter, 
with twelve or more slight undulations as in J7. undulata 
Say. A strong obtuse ridge extends from the beaks to 
the posterior basal angle as in Anodonta angulata, with 
a gentle curve, and the whole outline is very similar. 
The hinge, however, is that of a Margaritana, as 
shown in the figure. It is about one-seventh of the 
length of shell from the anterior end. Surface smooth, 
except near the beaks, with no irregularities else- 
where. Basal margin varying from slightly convex to 
slightly arched. Few variations in size or form in the 
specimens found, five of them nearly perfect. Length, 
2-25° inch’; height, “2.50; breadth, o:902* ‘The hinge, 
worked out from above in three shells, is like that of JZ. 
margaritifera, and the shell is thicker than that of Ano- 
donta, which led me to examine the hinge, a portion of 
which was exposed in one specimen. Its great resem- 
blance to A. angulata, however, arouses the suspicion 
that it may be the predecessor of that peculiar species, 
having lost its teeth by migrating from running water to 
quiet lakes, where teeth are not needed to secure the 
valves, and the shell decreased in thickness. Dr. A. A. 
Gould suggests such transformations as possible among 
living species, and if proved, they would aid very much 
in explaining the vast number of forms among our Amer- 


ican Unionide. All the California Anodontas inhabit

still water; the Margaritanas only rivers, though some 
may wash down into lakes. 

Found by Mr. W. L. Watts, in a fresh water deposit 
on the west border of the Kettleman Plains, a rolling up- 
land full of middle and late tertiary marine fossils. (See 
his report to the Mining Bureau on oil and gas.) 


THe KETTLEMAN LAKE BED. 


This fresh water deposit is about ten miles west of Tu- 
lare Lake, on the edge of what was probably a pliocene 
lake, about twenty miles long and five wide, or half as 
large as Tulare Lake is now, and south of west from it, 
in the western corner of Tulare County. It is now 400 
feet above Tulare Lake, which is itself 200 feet above 
sea-level. Unless the region has been much uplifted 
since the former lake existed, the two could not have 
been connected as one, but some proof of a great uplift 
is shown in the dip of the fresh water bed, which is 35° 
to the southwest. A far larger lake than Tulare no doubt 
existed in the pliocene epoch, if not later, but it could 
scarcely have been 600 feet deep, even before it broke 
through the Golden Gate. 

The following recent species were found in the same 
fresh water bed: 


1. Amanicola turbiniformis Tryon. Physa costata Newcomb. 


4 
2. Carinifex newberryi Lea. 5. Spherium dentatum? Haldeman 
6 


3. Goniobasis occata Hinds. Valvata virens Tryon. 


Of these Nos. 2, 4, 5 and 6 still inhabit Clear Lake, 
Lake County; Nos. 1, 3 and 6 live southward to Ala- 
meda County, but none are now known to inhabit any of 
the lakes or streams farther south. 

One other extinct species was also found which I have 
considered identical with one from Colorado(?), described 
by Conrad, as follows: 


168 CALIFORNIA ACADEMY OF SCIENCES. 


ANODONTA DECURTATA Conrad. Amer. Jour. of Con- 
chology, vol. vi, 1871, p. 200, described and figured from 
a cast said to be from Colorado. Plate xiv, figs. 5-8. 

The six specimens found differ considerably among 
themselves, partly from compression, partly, it may 
be, from sexual variation, so I have figured two 
of the best for comparison, especially as his was 
only a cast, and these have much of the shell. They 
show a striking resemblance to Conrad’s. No living 
species seems to be so short, and I would have called 
it a Unio, if I had not found the hinge well exposed. No 
Unio is known now to be living near the west coast. The 
specimens figured are of natural size. With them is one 
specimen more elongated, and perhaps a form of A. nut- 
taliana Lea, but too imperfect to decide upon. That 
species is fossil in several other localities of apparently 
assamcient date. joce bl. xiv, fie. 11. 


ihHEeASPHALTO IAKE DED. 


About forty miles southeasterly from the Kettleman 
bed, in Kern County, is a small fresh water deposit, also 
found by Mr. Watts, in 1893. This is eighteen miles 
northwest of Buena Vista Lake, and 1,100 feet above the 
sea, or 800 above the lake, and seems to have been up- 
lifted much more than the one described above, yet does 
not furnish so many species and none of them are extinct. 
It was perhaps entirely disconnected from the Tulare 
lakes, and is now nearly surrounded by hills, while the 
lake deposit of blackish marl has a dip of 80° northeast. 
The species brought from there are: 

1. Anodonta nuttalliana Lea. 3. Physa sp. 
2. Carinifex newberryi Lea. 4. Pomatiopsis intermedia Tryon.

small form being the only one yet found fossil in any lo- 
cality. It is even smaller than that found living in Clear 
Lake, which I have published as var. menor. No.3 a sin- 
gle broken specimen of the heferostropha group, very un- 
like P. costata. No. 4 is extremely abundant, often form- 
ing masses by itself. It is not now known to inhabit any 
of the neighboring streams, but is fluviatile in habits, and 
as most of the mountain streams dry up entirely in some 
years, it may have been thus exterminated south of Mon- 
terey Bay. 

The fresh water beds of this valley are still scarcely 
touched, and probably extend over a very much greater 
surface. They are not usually well exposed, and difh- 
cult to explore. They might be called miocene from 
their high dip, but this was no doubt from local causes— 
landslides, etc. 


THe ContTrRA Costa LAKE BED. 


This lies chiefly on the northeast slope of the hills west 
of San Pablo Creek, forming the boundary between 
Contra Costa and Alameda counties in that part of its 
course, about 4% miles northeast of the State University. 
A thin stratum of lignite was found there exposed on the 
side of a small branch of the main creek along the road 
going east to Lafayette, and tunnelling into the side of 
the hill exposed it in places farther north. It has a dip 
toward the northeast of about 30°, and probably contin- 
ues eastward under the valley, though not yet seen there, 
as the value of the lignite would not pay for boring. 

In the shaly layers of lignite I found a few fossils, of 
which figures are here given, and which lL eall:* 1; Ano-

The shells were crushed flat, but their outlines were so 
perfect and white in contrast with the black shale, that I 
had no difficulty in making perfect tracings of them. 
The engraver for the Mining Bureau took the liberty of 
trying to restore the surfaces, but it is evident that such 
crushed shells could not be properly represented as given 
in that report. Still there was no appearance of any sur- 
face characters except lines of growth. The figures are 
of natural size. 


TASSAJARA LAKE? BeEp. 


Along a small branch of Walnut Creek, in Alameda 
County, north of Livermore, is a deposit which contains 
chiefly living species, and was formerly called quater- 
nary, but one extinct species has been described from 
there, and its high elevation, nearly corresponding with 
the bed last described, makes it probable that it may bet- 
ter be called pliocene. The species were mostly given 
in the Catalogue of California Fossils, compiled by me 
for the State Mining Bureau’s report of 1888.

The last may be what I called Cochliopfa rowelli, as my 
specimens agreed nearest with the figure of that species 
in Binney’s work. It is also possible that some of the 
living species from horizontal beds along the creek are 
quaternary, being also found living in the creek, and now 
being fossilized, but others do not now live there. Sur- 
veys have not been made to determine whether the fossil 
beds extend up the hill slopes. 


PLIOCENE FRESH WATER FOSSILS. EE 


Tie SANTA CLARA LAKE BEDS. 


Fossil fresh water shells have been found at several 
points on both sides of this valley, and at different heights 
above it, but sufficient specimens have not yet been col- 
lected to determine the ages, elevations, disturbances, 
etc., of the various beds. The oldest known is that at 
San José Mission, where a ridge apparently of pliocene 
date remains as a remnant of a thick bed of gravel and 
alluvium once filling the greater part of the valley toa 
depth of probably 300 feet above tides. The same de- 
posit is seen at intervals from East Oakland along the 
foothills southward on the east side of the valley, and less 
abundantly on the west side to near Redwood City, but 
does not everywhere contain fossils. It 1s considerably 
disturbed in some places, usually by elevation of the 
mountains since its deposit. A dry gravel bed in the west 
end of Livermore valley may be of the same age, and 
bones of land animals are found in many places, some of 
them probably contemporaneous, some later. 

Dr. L. G. Yates first found the beds at San José Mis- 
sion, and I have visited them. The species obtained are 
the tollowing:

As no extinct species except Amanicola vatestana have 
been found in the other deposits in Santa Clara County, 
I will merely add a list of the species obtained from them, 
and await further collections and surveys. This species 
has also been found in a well bored in Tulare County at 
1,058 feet depth, and once probably existed as abundantly 
west of the Sierra Nevada as A. longingua did east of 
them, but is now extinct, as the latter is, except in Utah. 
The above list is continued as follows:

Santa Cruz Mountains, and in other deposits. 

Besides the fresh water shells mentioned above, there 
are nearly twenty species given in the Catalogue of Cal-

STUDIES IN CEANOTHUS. 
BY KATHARINE BRANDEGEE. 


The genus Ceanothus, as at present received, is entirely 
North American, and largely Californian; decreasing 
rapidly north, south and east both in the number of forms 
and of individuals and in size. It forms a considerable 
portion of the ‘‘Chapparal”’ of California, equaling or 
exceeding the ‘‘ Manzanitas’’ in quantity and outnum- 
bered only by the ‘‘Chamis.’’ The beauty and fra- 
grance of a blossoming hillside of Ceanothus make a 
strong impression upon all who behold it for the first 
time, and in consequence some of the species have long 
been cultivated in European gardens. 

Torrey & Gray in the Flora of North America recog- 
nized twenty-three species north of Mexico; eleven of 
them being there first characterized. Watson in Proc. 
Am. Acad. x, 169-175, admitted twenty-eight: reducing 
four of the previous list and describing one new species. 
Trelease in Proc. Cal. Acad. i, 106-118 (1888) raised the 
number to thirty-two, reducing one of the previous list, 
describing three new species and raising two varieties to 
specinc rank.- Dr. ©. C. Parry in two papers * increased 
the number to thirty-three, reducing five of the last list 
and describing seven as new (one of which he reduced 
in his second paper). Since that time seven species have 
been described 


all in.§ Cerastes. 

Of these revisions the last is the most important, being 
largely based on field studies, which in this genus are 
peculiarly desirable. Dr. Parry was the first to make 
known the prevalence of natural hybrids, the ease with 
which they are recognized in the field, and the corre- 
sponding difficulty of their determination in herbarium

specimens. On the other hand he neglected opportunities 
which would have added immeasurably to the value of his 
labors; thus he described C’. za¢rzcatus, from the summit 
of Mount Tamalpais, which he never ascended, though 
living for months at the time in its immediate vicinity; 
C. foltosus and C’. divergens from the flanks of Mt. St. 
Helena in perfect ignorance of the forms prevailing in 
the easily accessible upper portion, and he spent a con- 
siderable time in the Ojai Valley near Santa Barbara, 
without attempting to collect in their original locality the 
five species described from the latter place by Nuttall. 

One of the earliest undertakings of this study of Ceano- 
thus was the verification of thése species from the 
‘* bushy hills of St. Barbara.’’ In this investigation the 
conclusion was soon reached that C. divaricatus was 
invalid. Itis either a form of C. hirsutus or one of the 
abounding hybrids of that plant with C. spznosus. 
C. divaricatus has always been a source of confusion in 
Californian botany. It is represented in most herbaria 
by specimens of C. hirsutus (C. sorediatus), C. cordu- 
latus or C’. Palmert. C. oliganthus in typical forms is 
readily recognized, but grades into C. Azrsutus. Undue 
importance has been attached to Nuttall’s field notes. 
It was to his advantage to make as many new species 
as possible, and it may be noticed that his species are 
apt to run in pairs. In his original descriptions the re- 
iteration of the phrase ‘‘ with the preceding which it much 
resembles’ soon becomes wearisome. 

Every botanist who has dealt with the genus has borne 
convincing testimony to the interlocking relationships of 
the species and to the difficulty of their discrimination, 
and no two of them have been able to agree as to the 
limits of the species. 

The connecting forms of Ceanothus are still very im- 


STUDIES IN CEANOTHUS. 175 


perfectly known, and it will be many years before the 
species are even approximately settled. The set of about 
a hundred forms studied in the field by the writer and 
distributed to the principal herbaria of the United States 
is apparently the first attempt to bring these variations, 
with the necessary notes, to the attention of botanists. It 
has been too much the rule with collectors to neglect these 
connecting forms and gather only the typical or the ex- 
tremes. Imperfect as this set is it must convince every 
unprejudiced student of the genus that there are already 
far too many accepted. All the new species ‘recently 
proposed are intermediates between species themselves 
doubtfully separated by slight and inconstant characters. 

The species of Ceanothus are distinguished almost 
entirely by leaf forms. ‘There is no-constant character 
of fruit or flower by which any one of the species can 
be separated from others of the same section. The habit 
is so readily modified by environment as to be of small 
value. The character of penninervate or trinervate 
leaves which has been used to divide the Euceanothi 
fails completely. The presence or absence of marginal 
glands is not to be trusted, and the pubescence is ad- 
mitted to be variable; many of the species, as C. velutz- 
nus, C. cordulatus, C. arboreus, C. thyrsiflorus, C. Fend- 
lert, etc., having as now known glabrous as well as pu- 
bescent forms. 

All the species north of Mexico bloom in the spring— 
in the latitude of Central California, at moderate eleva- 
tions, from March till May. At elevations of 5,000— 
8,000 feet, from June to August. Along the Coast they 
often begin to blossom sparingly in January. All the 
western species bloom from the old wood, but often 
continue blooming on the new shoots. The inflorescence 
is axillary, the leafy peduncular shoot which in some 


176 CALIFORNIA ACADEMY OF SCIENCES. 


species is much elongated, dying after the fruit has 
ripened. The period of bloom is about six weeks, but 
many of the species bear flowers at other times. 

The hybrids of Ceanothus are found wherever two 
species of the same section grow together. As a-rule, 
to which there are, however, many exceptions, no two 
species of the same section (only two sections are here 
recognized) occupy the same area. Either one grows at 
a higher elevation or at a different exposure, and the 
hybrids occur along the lines of junction. They seem 
usually to be fertile, and show every gradation from one 
to the other parent. The only infertile hybrid, within its 
section, known to me is No. 69, C. zxcanus « papillosus. 
In this the ovaries are more or less abortive and no fruit 
was formed. Of the hybrids between members of the 
different sections only two are known, C. Veztchianus, 
which appears to be’ C. thyrstforus x C. rigidus ‘and 
C. rugosus, which is C. velutinus X C. prostratus. 
Nearly if not quite all the species described from Euro- 
pean gardens are hybrids of C. Amerizcanus and C. 
azureus—most of them artificial. 

Ceanothus is very readily and completely killed by the 
fires which so frequently run over the chaparral hills of 
California. About the places where their parents grew 
the seedlings then spring up in great numbers, although 
they are otherwise rarely seen. A certain proportion of 
these seedlings are always, where two different forms 
have grown intermingled, found to be hybrids. If the 
district should be again swept by fire before the seed- 
lings bear fruit the species in that locality would be ex- 
terminated, with perhaps an occasional sheltered exception, 
which may almost as readily be a hybrid as one of the 
parent forms. In this way, as may readily be conceived, 
a fertile hybrid might become established as the prevail- 


STUDIES IN CEANOTHUS. Ly 


ing form in a given district. Where the seedlings survive 
in great numbers, cross-fertilization being made certain 
by the swarms of insects attracted to their fragrant flow- 
ers, a continual crossing takes place, not only between 
the original forms, but between the hybrids and their 
parents on either side. 

Many of the species accepted in this paper are likely 
to prove too closely related as their forms become better 
known. No one, so far as Iam aware, has yet made any 
systematic attempt to collect over the whole area the 
forms of even the nearly allied Eastern species. The prob- 
able hybrid origin of several of the species raises a ques- 
tion of some importance, which may perhaps be easiest 
answered, as in the case of the willows, by propagating the 
distinct forms and hybridizing them artificially. 

In the pages following the original descriptions of nearly 
all the species, with the exception of C’. Amerzcanus and 
its well-settled synonyms, are republished verdbatznz, in the 
hope that future students of the group may find them as 
great a convenience as they would have been to the 
writer. The modification which descriptions undergo by 
increasing knowledge of their variations is often very 
great, and it seems to me the duty of monographers to 
give the original diagnoses in addition to their own, so 
that their readers may be in possession of the data neces- 
sary to form some sort of independent opinion, without 
the necessity of acquiring a considerable library.

Flowers beautiful blue, in compound umbellate fascicles, which are ag-

lowest fascicles arising from the axils of the uppermost leaves and some- 
what distant fromthe others. This variety has leaves greatly resembling 
those of C. Americanus, except that they are quite entire, while in the 
inflorescence it approaches C. thyrsiflorus. The specimens were without

Ceanothus integerrimus with the varieties enumerated 
above is the only species properly belongingt to the Cal- 
ifornian flora which shows entirely naked winter branches. 
The dead peduncular branchlets of the preceding year 
are often conspicuous below the fresh flowering, and, 
though not peculiar to the species, are to a certain extent 
distinctive. The range of variation is very great, as may 
be seen in No. 26, all the branches included under that 
having been collected within a few rods, and as no other 
species of the section was found in the vicinity, there 
could be no suspicion of hybridity. The leaf margin in

the typical form is ordinarily entire and glandless, with 
the exception of the single one terminating the midrib, 
but in var. Parry? and forms approaching it the margin is 
often dentate-glandular. Some examples otherwise near- 
ly typical are tridentate at the apex, each tooth terminated 
by a gland. The pubescence is commonly of straight 
hairs and most abundant beneath, but in a specimen from 
Forest Ranch, Butte County, otherwise typical, the hairs 
are crisped as is usual in var. Parryz. The lateral nerves 
of the leaves are often wanting in the narrower forms, 
but not constantly so in any; the texture is sometimes 
nearly as coriaceous as in C. sAznosus, which some of the 
forms approach rather closely in the nearly smooth pro- 
fusely resinous fruit as well as in the shape of the leaves 
and the absence of glands. The flowers are either blue 
or white in all the forms excepting var. Parryt, which, 
so far as known, has only deep blue flowers. The range 
of the species is from Washington to southern Arizona. 
Var. parvifolius in its extreme form has been collected 
only in the Sierra Nevada, but variations connecting it 
with typical ¢wtegerrimus abound in the Coast Range. 
All the forms are conspicuously absent from Southern 
and from Baja California. 

Var. Parry¢ was described from the vicinity of Calis- 
toga, at the foot of Mt. St. Helena. It abounds at eleva- 
tions of 2000-2500 feet on that mountain and the adja- 
cent ranges, and has been found at various places about 
Russian River, much nearer the seacoast. It seems to 
occur only in connection with C. ¢vtegerrémus and C. 
JSoliosus, and may be a hybrid. In this case the question 
can be best determined by direct experiment.

spinosus and C. integerrimus.—Trelease in Proc. Cal. Acad. ser. 2, i, 109 
(1888). 

Typical C. spznosus, as far as our present knowledge 
goes, is confined to the vicinity of Santa Barbara. It not 


unfrequently assumes a tree form which in size of trunk 


is second only to C. thyrstforus. The lateral nerves of 
the leaves are often developed, and the leaves of young 
bushes are strongly serrate toothed. The flowers are 
usually pale blue—sometimes white. No. 13. 

The variety is common on the lower slopes of the 
mountains bordering the San Joaquin Valley and of the 
southern part of the State, extending southward as far as 
Mount San Pedro Martir, in Baja California. It ordina- 
rily has usually 3-nerved leaves, and like all the species of 
this section, as well as C. entegerrimus, is either green or 


glaucous. The flowers are commonly blue but occasion- 


ally white, and in the form found on San Pedro Martir, 
which answers best to C. dévaricatus var. grosseserratus, 
deep purplish blue. No. 10, Nuevo, San Diego County; 
No. 11, Pasadena, Los Angeles County; No. 12, Tehach- 
api, Kern County; No. 108, San Pedro Martir, in Baja 
California. No. 68 is a hybrid of C. sfznosus and C. 
hirsutus. 

C. spinosus in all its forms is best marked by the 
rounded, extremely resinous fruit. In the fresh state it is 
not all triangular, and is quite destitute of protuberances.

earliest, gvosseserratus, perhaps named a hybrid; at any 
rate, specimens from near Nuevo, which agree with the 
description, are without doubt hybrids with C. tomentosus. 
Eglandulosus is conspicuously misleading as a varietal 
name of a species in which the presence of glands is 
ground for suspicion of hybridity. 


7. CEANOTHUS INCANUS T. & G. 


C. incanus: branches short and very thick, minutely canescent; leaves 
broadly ovate, obtuse, mostly subcordate, coriaceous, crenate-serrulate, 
minutely velvety above, whitish and canescent beneath [3-ribbed from the 
base]; clusters subsessile, axillary and terminal. California Douglas!/— 
Branches numerous, whitish with an exceedingly minute hoariness. 
Leaves an inch or more in length, rather crowded. Flowers white, in dense 
subglobose clusters, from very short and thick spurs or axillary branches.— 
Torr. & Gray, Fl. N. Am., i, 266 (1838). 


This is one of the best marked species, though approach- 
ing quite closely the preceding, from which in our pres- 
ent knowledge it is separated chiefly by its warty fruit. 
From the next it is distinguished by the same character 
and by its much greater size and different distribu- 
tion. It is found in scattered groups in both the outer 
and inner Coast Range, from Santa Cruz to Mendocino. 
The leaves are sometimes entirely glabrous. The large, 
thickly warty fruit is often 4-coccous. No. 4, Bradford,

in fasiculate clusters, somewhat conescent beneath.—Flowers in thyrsoid 
panicles one to two inches in length, springing from the summit or ap- 
proximate lateral branchlets; peduncle and pedicels sub-glabrous.—Calyx 
petals and pedicels white at the time of blossoming, but bright pea-green 
before expansion; panicles sometimes leafy at the base.—The form of 
flowers as usual in this genus; calyx divisions inflexed turbinate; petals 
saccate or hooded; unguiculate pistil three-parted about one-third its 
length. Fruit unknown.—This species appears to be near C. hirsutus 
(Nutt.); but the leaves are not ‘‘nearly sessile,” nor ‘‘ glandularly ser- 
rulate,” nor ‘‘ panicles terminal.” Nor does it answer to C. divaricatus 
(Nutt.), as the leaves are not ‘‘ grandularly serrulate,” and seldom half the 
size; nor arethe flowers ‘‘ blue.” [Washoe, J. A. Veatch].—Proc. Cal. 
Acad., 11, 124 (1861). 

From Oregon to San Pedro Martir in Baja California 
and eastward in the mountains of Nevada, at elevations 
of 4000—10,000 feet, principally in the Sierra Nevada, 
but occurring on Snow Mountain in Lake County. It is 
known as ‘‘snowbush”’ or ‘‘ bluebrush,’’ and forms en- 
tangled thickets 2-6 feet in height, the green and glau- 
cous forms often intermingled. Throughout California, 
as far as known, the flowers are white, but on San Pedro 
Martir they are of all shades, from white to purplish blue. 
The fruit is resinous, rarely warty, and with moder- 
ately developed crests. Some forms make a very close 
approach to C. zucanus. There are anomalous plants in 
the mountains of Nevada and Utah not yet sufficiently 
known which may possibly belong to some other species.

This species, very well marked by the resinous upper 
surface of the leaves, is of rather northern distribution. 
In California it hardly reaches below the middle of the 
State, unless it may be on the high mountains. Along 
the Coast it appears not to reach the southern border of 
Mendocino County. In the inner Coast Range it is not 
found south of Mt. St. Helena, Napa County. It is wide- 
spread in the Rocky Mountain region and in the ranges 
between the Rocky Mountains and the Sierra Nevada. 
Like C. cordu/atus it retains its leaves through the heavy 


the coast of North-West America, between the parallels of 40° and 
43 N. lat.? Douglas.—My character of this is drawn up from Mr. Men- 
zies’s specimen in my Herbarium. In Mr. Douglas’s MSS. he notices aC. 
grandis from the station above mentioned, which is probably the same as 
the present, although it inhabits a much more southern latitude. Our 
plant, however, it must be confessed, differs in no respect from the pre- 
ceding species, except in being everywhere, even upon the young leaves, 
entirely glabrous; whereas C. velutinus has, on the oldest as well as the 
youngest leaves a delicate, short, hoary, and almost white tomentum, 
clothing their under side.—Hook. Fl. Bor-Am., i, 125 (1830).

The range of this species is quite restricted. It is con- 
fined to a narrow strip along the coast from the northern 
border of California to the Santa Lucia Mountains in 
Monterey County and never occurs more than a few miles 
from the coast. In fact it is strictly confined to the red- 
wood belt. Of all the species it has the greatest range of 
unquestioned variation, both in size and in the form and 
texture of the leaves. It is commonly a rather tall shrub

branching near the base, but at Noyo, Mendocino County, 
it becomes a tree with clean trunk, 10-12 inches in di- 
ameter, unbranched for 4—6 feet and 25-30 feet in height 
with an equal spread of branches; while on the bleak and 
wind swept hills overlooking Point Lobos Signal Station

It is so far as known confined to the islands off the coast 
of California and is yet insufficiently known. It is com- 
mon on Santa Catalina Island, where, as Prof. Trelease

rarely arborescent. Mr. Brandegee collected on Santa 
Rosa Island a perfectly glabrous form of strikingly differ- 
ent appearance and with much smaller fruit. It was per- 
haps this form which led Prof. Sargent to refer the plant 
to C. velutinus. While it is too near other species to 
hold specific rank, it seems best to retain it until further 
field studies are made, especially of the forms found on 
Santa Rosa Island.

establishment, and was much struck by its beauty, the plant being at that 
time loaded with clusters of fragrant azure blossom. It has been since 
imported into this country from Mr. Parmentier’s collection at Enghien, 
by Messrs. Loddiges; and our drawing was made from a sample which 
flowered in their nursery at Hackney in April last. It is said to be very 
difficult to propagate, consequently likely to continue rare. Probably na- 
tive of Mexico, certainly of America, but not of New Holland, as has been 
stated elsewhere.—Bot. Reg., iv, 291, pl. 291 (1818). 


The accepted name of this species is a nomen nudum. 
It is in the place cited * simply mentioned as ‘‘ Ceanothus 
azureus azuré.b.’’ The diagnosis was not pub- 
lished-until 1818. Therefore ‘as ©! deruicns was pub- 
lished with a brief diagnosis in 1816 it should have been 
taken as the proper name, but as C. azureus has been in 
common use for nearly eighty years, it seems to me no 
good purpose can be served by changing it. 

The narrow-leaved form described by Dr. Watson is 
undoubtedly connected in complete series with the type, 
as is the case with similar forms of C. thyrsiflorus.

This species is still so little known that its affinities can

a common Ceanothus of San Diego County, which in this

This species has long been included in C. Azrsutus, al-

by such a series of intermediates that it seems best to 
consider C. Azrsutus merely a variety. The name olzgan-

The forms of this species have been more troublesome 
to botanists than even those of C’. sfznosus or C. tnteger- 
rimus. C. divaricatus answering to Nuttall’s description 
and fragmentary specimens, is not recognizable as a valid 
species at the type locality. It is there represented by 
many slightly differing forms, either variations of C. 
hirsutus or hybrids of that species and C. spznosus. 
Under the name of C. dzvaricatus in most herbaria there 
are usually to be found C. spznosus var. Palmeri; C. 
cordulatus, or the more rigid forms of C. sorediatus. 

C. soredzatus is merely the northward extension of C. 
hirsutus, and C. ¢ntricatus is as its author came to know 
only C’.. soredzatus in its smaller and more rigid growth.

In the Botany of California this plant which is found at 
elevations of 1,000—2,000 feet in the central Sierra Ne- 
vada, was included under C’.. soredzatus. It bears a con- 
siderable resemblance to forms of C. azureus, but differs 
in leaf outline and tomentum. C. azareus Kell. is the 
older name but was palpably a misprint. Possibly Dr. 
Kellogg discovered after its publication that there was an 
earlier C’. azureus, for he did not correct the spelling when 
the first volume of the Proceedings of the California Acad- 
emy of Sciences was reprinted. C. uztzdus referred in 
Bot. Cal., Watson’s Index and the Kew Index, to Pac. 
i hep. ivy 75,15 not to be found at the place cited, or 
elsewhere in the Survey volumes. No. 35, Ione, Amador

In this variety is included a plant from Southern Cali- 
fornia, which is about equally related to C. tomentosus and 
C. hirsutus. It is represented in this distribution by No. 
33 from San Diego; No. 34 from Encinitas and No. 36

slightly nodding. Leaves oblong-ovate or elliptical-ovate, obtuse, or sub- 
acute, 3-nerved, in most of the young leaves the lateral nerves are obscure; 
lamina thin membranous, densely villous, bluish green and slightly 
glabrous beneath, shorter villous pubescent above, not shining, retuse- 
mucronate-dentate; teeth somewhat cuspidate, glandular, petioles about + 
the length of the leaf. Flowers in long axillary, simple racemes, some- 
what pendant, flowers mostly crowded into a corymbose cluster at the 
extremity on pedicels of 4 to 3 of an inch long, colored racemes 2 to 3 
inches long; scarcely leafy at the base, although a few scales are observed, 
and occasionally a very minute leaf; flower buds covered with small pu- 
bescent bracts, at length deciduous, —calyx more infolded, and less cowled 
than usual in this genus, giving the flower an angular or ribbed appear- 
ance, style exserted, united to the top, stigma barely divided, branches 
green, colored on the sunny side, and studded with small flat glandular

Dr. Kellogg’s name is much the older, but his descrip-

it to be referred toa different species. There is no doubt

ovate, obtuse, narrowed at base toa short petiole, irregularly crenate, with 
frequent resinous glands, obscurely triple-nerved near the base, not revo- 
lute at the margin but inclined to fold back on the midrib; inflorescence 
terminal and axillary, loosely globose, or slightly elongated; flowers few, 
on short pedicels, light blue; fruit triangular, 3-4 mm. broad, sharply 
crested at thesummit. Habitat:—A densely branched shrub, 3-5 feet high 
with light green leaves, more or less resinous glandular; has been referred 
to C. dentatus—included above as a variety of C. papil/osus—from which it 
differs in every essential character. In its general features it comes nearest 
to the South Atlantic coast species, forming with them a well-marked 
group, approximating the section [CERASTES] following. The specimens 
seen were collected in the upper Napa Valley, where it is abundant, being 
associated with C. Parryi and C. divergens.—Parry in Proc. Davenp.

found on Tamalpais seems to be far enough removed 
from either C. decumbens or C. Lemmonz, but they are 
all closely connected by forms common in Lake and 
Mendocino counties. C. folzosus has been usually con- 
sidered a form of C. dentatus, to which it is indeed

Ceanothus dentatus: branches (and veins of the leaves beneath) tomen-

oblong-cuneiform, retuse, toothed, with revolute margins, more or less 
hairy on both sides [l-ribbed, pinnately veined]; peduncles elongated, 
nearly terminal; thyrsus oblong, of numerous umbel-like fascicles; ovary 
with three protuberances at the summit. California, Douglas/—Leaves 
scarcely half an inch long, strongly and remotely feather-veined, pitted 
beneath, irregularly and obtusely toothed. Peduncles an inch or more in 
length. Flowers crowded, white.—Torr. & Gray, Fl. N. Am. i, 268 (1838). 

This species in its typical form appears to be confined 
to the vicinity of Monterey. It is quite possible that a 
better knowledge of its extension and variations will show 
that it should include C. decumbens and its forms. The 
general habit and texture is the same, which counts for a 
great deal where the differences between species are so 
very slight. No. 51, Monterey (flowers white in some of 
the specimens). C’. zmpressus appears to be nothing but 
a stocky southern form growing on unsheltered sandhills. 
Mrs. Lemmon’s locality for the form is unknown, but 
both Mr. L. Jared and Mrs. Ida M. Blochman have col- 


lected it near San Luis Obispo.t

Ceanothus papillosus. branches tomentose; leaves narrowly oblong, much 
crowded, fascicled in the axils, densely and softly tomentose beneath, 
glandularly denticulate on the margin [l-ribbed, pinnately veined]; pe- 
duncles aggregated, clusters somewhat capitate; ovary triangular, the 
angles projecting at the summit. California, Douglas/—Branches terete. 
Leaves 1-1} inch long (those fascicled in the axils smaller), fringed on the 
margin with numerous capitate glandular teeth; the upper surface con- 
spicuously papillose and somewhat hairy. Peduncles numerous at the 
summit of the branches; the flower-buds at first invested with ovate 
woolly bracts: pedicels 2-3 lines long. Flowers blue.—Torr. & Gray, FI. 
N. Am. i, 268 (1838). 


In Dr. Parry’s revision of Ceanothus C’. dentatus was 
reduced to C’. fapillosus. He had not then seen C. den- 
tatus growing, and after so seeing it, altered his opinion. 
He was, however, without knowledge of the forms since 
collected, and contrasted the typical forms of each. The 
epidermis of C’. Papillosus is occasionally white and de- 
ciduous as is shown in No. 56, and even in some spec- 
imens of Parry’s distribution, a character which strength- 
ens its relationship to C. Lemmonz. Miss Eastwood has 
collected specimens in the Santa Lucia Mountains with 
lilac flowers, and extremely narrow leaves, which are 
closely revolute. The range of the variety is shown 
by the localities given for the specimens. On the bare 
grassy mesas sloping upward from the sea at San Sim- 
eon, it grows prostrate on the ground, often entirely 
hidden by the grass and stunted weeds. This form, 
No. 53, is frequently quite destitute of papillae. No. 53,

gerrimus, C. tncanus, C. thyrsifiorus and C. hirsutus.

§ Cerastes. 


Leaves usually opposite, pinnately-veined, coriaceous, 
persistent, never glandular; subulate stipules deciduous 
from the persistent corky base. Fruit never resinous, 
hardly sulcate between the cocci, usually with conspicuous 
hornlike protuberances above the middle. Species all 
very closely related, perhaps best treated as varieties of a 
single species.

Douglas MSS.—Has. North-West America. Abundant near the sources of 
the Multnomak River, in sandy soils, growing under the shade of Pinus 
Lambertiana. Douglas.—I have retained this in the genus Rhamnus, it 
being so named by Mr. Douglas in the Herbarium of the Horticultural 
Society: but when its flowers and fruit shall be known, it will probably 
prove to be something very different, even from the Order Rhamnew. It 
constitutes a harsh shrub, from four to twelve feet high, with numerous, 
stout, rigid, terete, opposite, subpatent, and subspiniform branches, very 
leafy, and clothed with a rusty-coloured down. Leaves the largest of them 
scarcely an inch long, and those oblong, cuneate at the base, while those 
on the younger parts of the branches are more decidedly cuneate, and 
smaller, all of them opposite, bearing clusters of young leaves and 
branches in the axils, coriaceous, the margins slightly revolute, entire, the 
apex obtuse, retuse, emarginate, and sometimes tridentate, glabrous, and 
very obscurely obliquely nerved on the upper surface; beneath downy 
with the nerves oblique, close, prominent, brown, and reticulated with 
transverse veins, the areole of these veins, when seen under a microscope, 
are filled with a beautiful, short, dense fascicle of hairs, which hairs orig- 
inate in a circle, and all converge towards the centre of the little tuft, lying 


*C. CUNEATUS var. RAMULOSUS. Smaller, the branchlets more humerous 
and more leafy: leaves narrower and longer, more tomentose beneath: fl. 
half as large, scentless, deep blue: fr. smaller and more elongated.—The 
type abundant at middle elevations throughout our whole district, extend- 
ing northward to the Columbia: the variety in the Coast Range only, and 
from Santa Cruz Mts., Greene, to Marin and Napa counties, Mrs. Curran.

nearly flat. From the axils of some of the leaves, and from a terminal 
pair in others, arisesa peduncle? clothed with rusty-brown hairs, and bear- 
ing a globose bud, or cluster of buds (apparently of very young flowers), 
surrounded by small, rusty, closely-pressed bractew? But of the nature 
of these flowers I can make nothing. The whole plant yields, even when 
not rubbed or bruised, a balsamic odour like that of some Balsam-Poplars, 
mixed with a powerful astringency resembling the smell of young Birch 
twigs.—It is to be hoped that during his present arduous journey through 
North-West America, Mr. Douglas will obtain flowering and _ fruit-bearing 
specimens of this singular plant.—Hook, Fl. Bor-Am., i, 124 (1830). 
Through the northern part of its range C’. cuneatus is 
moderately well defined. In the region of the central 
Sierra Nevada it barely reaches the altitude of 4000 feet, 
and at this elevation is only 2-3 feet in height with droop- 
ing branches. In the foothills of the great valley of 
California it is a rather rigidly upright bush, with white 
flowers, and often covering a large extent of country; it is 
above bushes called ‘*chapparal.’’ In Lake County the 
prevailing form has very small leaves. In the Coast Range 
it reaches its largest size, and the flowers run through all 
the shades from white through lilac to deep purple-blue.

little fascicled in the axils, thick and coriaceous, obovate-cuneate, entire, 
often emarginate, glabrous above, whitish and minutely tomentose- 
canescent beneath, [l-ribbed, pinnately veined]; flowers in lateral pedunc- 
ulate nearly simple umbels; fruit very large, with three projecting horn- 
like appendages at the summit.” Mountains of St. Barbara, California, 
Nuttall/—A shrub 3-6 feet high. Fruit twice or thrice as large as in the 
preceding.—Torrey & Gray, Fl. N. Am., i, 267 (1838). 


With this I would include the ‘‘C. crass¢folius’’ ot the 
lists from Santa Catalina and Santa Cruz islands, which 
is indifferently either alternate- or opposite-leaved. C. 
macrocarpus is said in Flora Franciscana to belong to 
the ‘‘Summits of Santa Ynez Mountains.’’ I found it 
to be most common at low elevations. The fruit, as will 
be seen, is very variable in size. The shrub at Santa 
Barbara appears to be constantly alternate-leaved, but 
just beyond the summit of the pass occurs C. cuneatus 
(No. 95) with opposite leaves and scarcely otherwise to 
be distinguished. The character is evidently of no spe- 
cific value in view of the behavior of the island form. 
Alternate leaves are occasionally found in other localities, 
on vigorous shoots of otherwise normal plants. No. 89, 
Santa Barbara: No. 88, Santa Catalina Island.

the veins of the lower surface of the leaves) somewhat canescent, with a 
rusty-colored pubescence; leaves alternate, approximate or crowded, very 
thick and coriaceous, roundish-oboyate or cuneate-oval, often emarginate, 
[l-ribbed, pinnately veined], the younger ones sometimes obscurely ser- 
rulate, glabrous above, minutely tomentose-canescent beneath; umbels 
axillary, few-flowered, naked; fruit with minute protuberances at the 
angles. Low hills near the coast, St. Diego, California.—Leaves about 
half an inch long and 4-5 lines wide, similar to the preceding in texture, 
venation, &c. Flowers white. Fruit the size of a large pea.”—Very near 
C. cuneatus (, and perhaps only another variety of that species; from 
which it differs, however, in its broader leaves and tuberculate stems, as 
well as in the minute tubercles of the fruit.—Torrey & Gray, Fl. N. Am., 
i, 267 (1838).

Under this variety it seems best to include nearly all 
the forms of the Cerastes section which have opposite 
more or less dentate leaves and conspicuous warty stip- 
ules as in typical C. verrucosus. Some of the forms 
make a close approach to C’. cuneatus, while others con-

CEANOTHUS RIGIDUS var. GRANDIFOLIUS. Punta de los Reyes; April 18. 
The leaves are three times larger than in the ordinary form of this species, 
and strongly spinose-toothed on the sides, as well as at the extremity. This 
variety seems to show almost a transition to C. prostratus through the 
broad-leaved form of that plant noticed below; but we are not willing to 
unite the two species, without seeing a more extensive suite of specimens 
for comparison.—Torr in P. R. R., iv, 75 (1857).

Flowers small. Fruit about 2 lines/in diameter.—I have only poor speci-

forms of C. cuneatus, NVutt.; but the leaves are not narrowed towards 
the base, and the pinnate veins underneath are obscure.—Gray in Plante 
Wrightiane, ii, 28 (1853). 


C. Greggit, of which I have not seen the type, is al- 
most equally connected with C. r7g7dus and C’. cuneatus. 
To itis perhaps best referred C. vestztus* (part of No. 
99, from Tehachapi), though it is apparently quite as near 
some of the forms referred to the next variety. Speci- 
mens of C. rzg7dus collected at San Simeon (No. 92) 
are intermediate between C’. Greggzz and C. rzg7dus, and 
connect closely with the next variety.

senting the species, are 5-9-toothed. The fruit in all the

forms here included differs from that of all other species 
in being more fleshy and often bright red, and the protu- 
berances from the upper part of the fruit are ribbed and 
unusually prominent. Through the forms of its variety 
pinetorum it approaches closely both the northern and 
southern forms of C’. r7g7dus, but if not held apart from 
that species the whole Cerastes section would have logi- 
cally to go as varieties under C’. cuneatus. No. 70, Don-

The hybrids in this collection have been mentioned under 
C.velutinus, and under C’. cuneatus, with which it mixes 
freely in all degrees. In all the observed hybrids the 
fruit resembles C’. cuneatus, except in one instance, a 
specimen collected at Susanville, Lassen County, not in 
sufficient quantity for distribution. 


Var. DIVERGENS (Parry). 

C. divergens, un. sp. Branches rigid, divergent, hoary pubescent 
when young; leaves 10-20 mm. long, 5-10 mm. broad, very rigid coria- 
ceous, cuneate at base toa very short petiole, broadly truncate at sum- 
mit, with prominent midrib, the principal pinnate veins terminating in 
sharply mucronate broad serratures, dull green above, with distinct rows 
of tufted areolar pubescence beneath; inflorescence in short umbellate 
peduncles, occasionally subtended by one or more leaflets; fruit oblong, 
5 mm. broad, 8 mm. long, deeply immersed in the rigid disc; exocarp 
spongy, light pink before maturity, the appendages at the summit of 
the cocci conspicuously horned, with accessory intermediate crests. 
Habitat:—A low-branching shrub, the long divergent branches inclined 
to support themselves on adjoining bushes, but never decumbent. Flow- 
ers in April, fruit July; only known from a single locality in the in- 
teresting botanical district of the Napa Valley. Though closely allied 
to C. prostratus, with which, in herbarium specimens, it is easily con- 
founded, it is clearly distinct in habit and foliage, as well as a widely dif- 
ferent geographical range. Like all the species of this Section, the explosive 
character of the capsules is very apparent to any one who would under- 
take to collect fully mature seeds.—Parry in Proc. Davenp. Acad. v, 173 
(1889).

per, Dr. Parry, probably from age and feebleness, did 
not ascend the mountains on the slopes of which he de- 
scribed species of Ceanothus, and was therefore often 
misled as to their range of variation. C. dzvergens was 
described trom low elevations but higher up and on the 
northward slopes of the same and the adjacent Cobb 
Mountain it grows in just as flat squaw-mats as are found 
in the Sierra Nevada, though the fruit is much smaller 
and the leaves more spinose. No. 73, Cobb Mountain,

Var. PINETORUM (Coville). 

CEANOTHUS PINETORUM Sp. noy. PLATE VI. Plant of the sub-genus Ce- 
rastes, 0.6 to 1 meter high, densely branched; branches divaricate, dark 
brownish red when young; leaves opposite; stipules at maturity nearly as 
thick as broad, ovate in outline, acute, divaricate, reflexed, from 2 or 3 to 
5 mm. long, light brown, glabrous, spongy, and when old powdery within; 
petiole 1 to 2 mm. long; blade broadly oblong, rounded at base and apex, 
0.5 mm. thick, commonly 12 to 16 mm. long, glabrous or with traces of 
early pubescence, spinulose-dentate, with 4 to 6 teeth on each side, the 
under surface venose-reticulate, with minute white areolxw; flowers not col- 
lected; fruiting peduncle 0.5 to 1.5 em. long, about 2 mm. thick; fruiting 
pedicel of about the same length, somewhat slenderer; fruit 7 to 9 mm. 
long in addition to the crests, these about 3 mm. long; seed oblong, about 
4 mm. in length, black and shining at maturity.—Type specimen in the 
United States National Herbarium, No. 1738, Death Valley Expedition; 
collected August 30, 1891, near Lyon Meadow, Sierra Nevada, Tulare 
County, California, by Frederick V. Coville.—The species was seen only 
in the forests of Pinus jeffreyi, on the head waters of Kern River, in the 
valley that lies between the two main crests of the Sierra Nevada. The 
very large fruit, the form of the leaves, and the erect habit of the plant 
distinguish it from all the species of the sub-genus. In our specimens 
the conspicuous enlargement of the stipules is remarkable.—F. V. Coville 
in Contr. U.S. Nat. Herb., vol. iv, 80 (1893). 


With this is included C. Yepsonzz,* which differs in its 
more undulate leaves and less corky stipules. Besides

the type locality Ceanothus pinetorum was collected on a 
sand bar of the Kern River, near Kernville, in 1891, in 
flower. Its flowers were blue. The form described as 
C. Fepsoniz is common at middle elevations in Lake 
County, where it is a very rigid bush 4-7 feet high, 
with rather large white flowers. This form is farther re- 
moved than any of the others from typical C’. frostratus, 
but it is brought nearer by the coast forms. Thus at 
Liberty’s, Marin County, and similar elevations of a few 
hundred feet in that neighborhood, it is still a rigid up- 
right bush, but with blue or purple flowers; while on the 
neighboring flanks of Tamalpais at elevations of 2000 
feet or more its branches droop often to the ground, 
much in the manner of the variety divergens. No. 79

I. Hybrids of Euceanothus. 


It was formerly the custom, now happily somewhat 
fallen into neglect, to describe species from plants prop- 
agated in gardens, with small inquiry as to their origin. 
To this practice we owe all the specifically named hybrids 
of Euceanothus. Nearly all of them were produced by 
the crossing of C. Americanus and C. azureus, and their 
derivation was probably suspected in most cases, as may 
be seen by occasional notices in gardening journals.*

Ceanothus Neumanni. Tausch Dendr. ex.-boh. exs.: foliis ovatis serrul- 
atis 3-nerviis sub-pubescentibus, thyrsis axillari-terminalibus subcorym- 
bosis, in corymbum densum congestis, capsulis congestis rugosis 3-carina- 
tis (majoribus).—In hortis promiscuus cum C. americano L. obvenit, qui 
differt thyrsis oblongis in paniculam dispositis, capsulis levibus multo 
minoribus non subulato carinatis. In botanicis indefesso et amicissimo

Ceanothus collinus. In the nursery of Messrs. Low & Co. this pretty 
species is at present blooming. * * * Its ovate deeply furrowed and 
serrated leaves are of a very symmetrical character and the flowers, which 
appear in terminal thyrses like those of C. azureus. are pure white.— 
Paxton Mag. of Bot. vi, 140 (1839). 


Ceanothus pallidus ; caule arborescente ramis ramulisque pubescentibus 
teretibus, foliis triplinerviis ovalibus serratis supra glabris nitidis subtis 
viridibus pubescentibus, floribus thyrsoideo-paniculatis: pedicellis capi- 
tato-corymbosis pilosis.—This plant occurs in the gardens under the 
name of Ceanothus ovatus and thyrsiflorus, from both which it is certainly 
distinct. The first is a mere variety of Ceanothus Americanus, and the 
latter is a Californian tree with deep-blue flowers and very strongly angu- 
lar branches. It approaches more nearly to the lovely C. azureus, but its 
leaves are green, not hoary beneath, and the flowers are smaller as well as 
much paler. If it were probable that such a thing would happen, this 
might be suspected to be a cross between C. azureus and Americanus.— 
It is a beautiful shrub and much hardier than Ceanothus azureus; during 
the summer and autumn months it flowers freely, if trained to a wall with 
a south aspect.—It strikes readily from cuttings of the half-ripened wood 
during autumn, and grows well in any soil, if not too poor or too wet. 
The accompanying figure [flowers pale lilac] was taken from a plant in 
the garden of the Horticultural Society, which was presented by the 
Messrs. Baumanns, of Bollviller, under the name of Ceanothus ovatus.—

qui représente le Ceanothus axillaris, et qu’on réfléchit que cette plante sort 
du Ceanothus azureus grandiflorus, ’on comprend que nous ayons encore 
dérogé aux habitudes suivies en botanique, de faire porter 4 Venfant le qua- 
licatif de sa mére, afin d’en démontrer V’origine. Nous aurions d’abord 
du ajouter un troisiéme qualicatif pour désigner l’enfant, ce qui aurait 
fait Ceanothus azureus grandifiorus axillaris; de plus, il y aurait eu non 
sens, un illogisme, ce qui, du reste, arrive presque toujours quand on veut 
suivre la filiation généalogique des noms qui, contraire 4 la marche des 
choses, est généralement en contradiction avec les faits. En effet, outre 
le port ou faciés qui différe de celui du C. azureus grandiflorus, les fleurs, 
au lieu d’étre grandes et d’un bleu d’azur foncé comme chez ce dernier,

Hybrid of C. ¢hyrs¢florus and C. dentatus. 


Il. Hybrids tn § Cerastes. 

The two following are hybrids of C. cuneatus and C. 
prostratus: 

Ceanothus connivens. A low shrub with elongated, nearly simple, weak 
and flexible trailing branches 3 feet long or more, forming a depressed 
tuft: leaves opposite, coriaceous, cuneate-obovate to oblanceolate, an inch 
long or less, entire except at the truncate or retuse and mostly 3-toothed 
apex, glabrous and rugulose above, white-tomentulose between the veins 
and veinlets beneath: fruit in umbelliform clusters at the ends of short 
terminal branchlets, small, the conspicuous horns closely appressed to 
the surface of the exocarp, connivent and overlapping at the end of it.— 
Calaveras County, Calif., in dry oak woods near the Half-Way House, be- 
tween Murphy’s and the Big Trees, 19 June, 1889. As a new member of the 
Cerastes section, exceedingly well marked in its fruit character, it has a 
flexibility of stem found in no other nothern relative; although C. verru- 


° 


STUDIES IN CEANOTHUS. 217 


cosus of the table lands of southern California and of the peninsula is 
like it in this respect. But C. connivens is nearly prostrate through mere 
lack of firmness or hardness in wood fibre. It, however, evinces none of 
the rooting and matted character of the not yet well-described but most 
distinct C’. prostratus.—Along the bleak summits of the Siskiyou Mount- 
ains of southern Oregon I observed in September a Ceanothus much like 
this in leaf character; the stems depressed but not prostrate, less flexible 
and stouter. In the absence of fruit, one could not say whether it could 
be referred to this or whether it would be a stunted growth of C’. cuneatus 
with truncate and notched leaves. The zeal and diligence of Mr. Howell, 
who has easier access to the region indicated, it is to be hoped may settle 
the question by collecting it in fruit some day.—E. L. Greene in Pitt., 11, 
16 (Noy., 1889). 

Ceanothus pumilus. A rigid depressed much branched evergreen under- 
shrub, the branches often rooting at the joints and from a few inches to 
a foot or more in length: leaves opposite, very small (3 to 5 lines long), 
rigidly coriaceous, glabrous above, very minutely white-tomentose between 
the veins beneath; entire except at the usually 3-toothed apex, the general 
outline from oblanceolate to obovate-oblong: flowers in numerous sessile 
umbels, rather pale blue: fruit unknown.—On hillsides near Waldo, Oregon, 
April 1892, Thomas Howell.—E. L. Greene in Erythea i, 149 (July, 1893). 


Ill. Mybrids of Euceanothus with Cerastes. 


These are very rare. Only two have been observed and 
neither has been found a second time. Neither of them 
appear to set fruit. The first is almost certainly a hybrid 
of C. thyrstforus and C. rigzdus. The second is without 
doubt a cross between C. velutinus and C. prostratus. 
Only one plant has been seen and the discoverer reports 
that it flowers very sparingly and does not fruit at all. 
Examination of the flowers shows that the pistils are dis- 
torted. Prof. Greene considered C. cuneatus to be one 
of the parents, which is practically impossible, as that 
species does not occur within thirty miles of the locality. 


Cranotuus Veitchianus; ramis foliis superne petiolis, pedicellisque 
glaberrimis, ramulis ultimis rachique inflorescentiae tomentosis, foliis

cuneate, rounded at the apex, margin rather distantly toothed, each tooth 
terminated by a deciduous gland. Heads of flowers one to three inches 
long, forming when in bud broadly ovoid cones at the ends of the branch- 
lets, covered with imbricating, silky scales. Rachis stout, villous. Pe- 
duncles slender. Calga-lobes erect or incurved, triangular. Petals with 
rather long claws, and very broadly obovate, deeply cucullate lamin, of 
a bright deep blue color, as are the pedicels, calyx and stamens. Ovary 
depressed, three-lobed, lobes tumid at the apex. California, William 
Lobb.—Hook. in Bot. Mag. vol. Ixxxv, t. 5124, June 1 (1859). 

C. rugosus. Stems stout but pliable, prostrate, glabrous in age, the 
growing parts canescently puberulent: leaves coriaceous, 3-14 in. long 
including the short petiole, oboyate- or elliptic-oblong, acute at both ends, 
closely and saliently spinulose-serrate, 3-nerved, finely rugose on both 
faces, tomentulose beneath: fl. pale blue or white, in a short nearly simple 
raceme, the peduncle equaling the leaf.—-Top of a high hill near Truckee, 
June, 1890. Sonne. Doubtless a hybrid of which C. cuneatus is one of the 
parents. Mr. Sonne suggests that C. velutinus may be the other. The 
young leaves are subtended by triangular-subulate stipules a line long.—

OBSERVATIONS UPON THE HETEROPTEROUS HEM- 
IPTERA OF LOWER CALIFORNIA, WITH DE- 
SCRIPTIONS OF NEW SPECIES. 


IB Ye Sen tee Ele ER 


A collection of Hemiptera from Lower California has 
been placed at my disposal for study by Dr. H. W. Hark- 
ness, President California Academy of Sciences, where 
the types now are. Through the zealous interest of Dr. 
Gustav Eisen, who made the largest part of this collection, 
under the auspices of the California Academy of Sciences, 
our knowledge of the fauna of Lower California has 
been greatly extended and increased. Hitherto, the col- 
lections made by Mr. John Xanthus de Vesey, Baron 
von Osten Sacken and Henry Edwards, have been almost 
the only sources of reference for information relative to 
the Hemiptera of that country. The assemblage of 
forms now known from the region near Cape St. Lucas 
numbers somewhat over one hundred species. Doubt- 
less many more species will yet be secured when sufficient 
time can be devoted to close collecting. From the entire 
peninsula, including a few of the islands along the coast, 
as well as some of those in the Gulf of California, about 
three ,hundred ‘species have thus far been collected. 
Taken as a whole, the assemblage of species is Mexican, 
and it forms a part of that which extends into Arizona, 
to which the name Sonoran has been applied. A very 
small percentage, embracing such forms as Pachycoris 
torridus Scop., Pachylis gigas Burm., and SPphictyrtus 
bugabensis Dist., which form no necessary part of the 
Sonoran, but which belong to an overflow of the tropical, 
has been made possible by the long stretch of coast, the 
sufficiently prolonged high temperature, and the not dis- 
tant lands from which tropical forms could be readily 
transported. Accordingly, the writer does not regard 

2D SeR., VoL. IV. June 20, 1894. 


224 CALIFORNIA ACADEMY OF SCIENCES. 


these forms from the region of Cape St. Lucas as au- 
tocthonous, but as incidental, and not well settled. Forms 
affecting cacti and plants of the dry wastes hold their 
position to a remarkable degree; but they are so few in 
number as to form only a small exception to the truly in- 
digenous fauna. 

The list given below embraces all the species which 
have been examined by the writer from any part of the 
great peninsula of Lower California, excepting only such 
new forms as were too mutilated to be referred to their 
genera. About thirty species, known to me only by 
fragments, still remain to be recorded, among which are 
some interesting Capstd@e, collected by Dr. Edward 
Palmer, on the islands along the coast. 

An enumeration of the well recognized species shows 
that the peninsula is inhabited by 5 Pachycoride; 6 
Corimelenide; 7 Cydnide; 39 Pentatomide; 42 Cor- 
eid; 2 Berytide; 41 Lygeide; 7 Uarcide; 50 Cap.

collected at several localities on the peninsula by various 
persons. 


CORIMELENA PULICARIA Germ. Specimens were se- 
cured near Cape St. Lucas and at San José del Cabo. 
It occurs from British America to Central America. 


CORIMELENA C4ZRULESCENS Stal. This species appears 
to be less abundant on the peninsula than the smaller ones, 
as specimens usually occur singly, or only in pairs, at the 
localities from which they have been taken. From San 
José del Cabo by Dr. Gustav Eisen, and from Cape St. 
Lucas by John Xanthus. 


CORIMELZNA LATERALIS Fab. This species spreads on 
the Pacific coast from British Columbia to Cape St. Lucas.

CYDNIDZ. 


CyRTOMENUS MIRABILIS Perty. Thisisa common species 
near Cape St. Lucas, and it is widely distributed from 
the region as far south as Rio de Janeiro, Brazil, north- 
ward through Central America and Mexico to southern 
Texas, and from thence through the Gulf States to 
Florida. — 


AMNESTus pusILLUS Uhler. Specimens were obtained 


HEMIPTERA OF LOWER CALIFORNIA. 227 


from the vicinity of Cape St. Lucas by Mr. Xanthus. 
This small insect lurks beneath rubbish in sandy places, 
where it matches the color of the ground and is thus 
easily overlooked. 


TRICHOCORIS CONFoRMIS Uhler. One specimen was 
secured near Cape St. Lucas by Mr. Xanthus, and Henry 
Edwards had other specimens which were collected far- 
ther north on the peninsula. A single specimen was ob- 
tained at Comondu, in March, by Mr. Charles D. Haines.

be uncommon on this peninsula. But I have examined 
one obtained from. near Cape St. Lucas, and another 
from some point farther north on the peninsula. 


OpLomus picHrous H. Schf. var. A beautiful male of 
this species was taken near Cape St. Lucas by John 
Xanthus.

taken near Cape St. Lucas by Mr. John Xanthus. It is 
common in Southern California and Arizona. 


BROCHYMENA oBscuURA H. Schf. Obtained at Cape 
St. Lucas by Mr. John Xanthus. It seems to be common 
in most parts of temperate Mexico, and to extend north 
in California and Oregon. Specimens were taken at 
Comondu, in March, by Mr. Charles D. Haines. 


NEOTTIGLOSSA SULCIFRONS Stal. One specimen was 
secured by Mr. John Xanthus near Cape St. Lucas. 


CoOSMOPEPLA DECORATA Hahn. Numerous specimens 


HEMIPTERA OF LOWER CALIFORNIA. 229 


were collected at San José del Cabo by Dr. Gustav Eisen. 
Itis a common Mexican form, which is found also near 
Cape St. Lucas and on the northern part of the peninsula. 


COSMOPEPLA CONSPICILLARIS Dallas. This form occurs 
in the northern part of the peninsula, but no specimens 
were secured at Cape St. Lucas. It seems to be more 
common in Oregon and Washington. 


CEBALUS PUGNAX Fab. A few specimens were brought 
from near Cape St. Lucas by Mr. John Xanthus. 


MOoRMIDEA PICTIVENTRIS Stal. var. The variety with 
small white dots is quite common at Cape St. Lucas, from 
which‘place Mr. Xanthus brought numerous specimens. 


EUSCHISTUS TRISTIGMUS Say. A form of this species 
is distributed over various parts of the peninsula of Cali- 
fornia, even as far south as Cape St. Lucas. 


EUSCHISTUS IMPICTIVENTRIS Stal. This species is also 
to be found as far south as to near Cape St. Lucas. 


EUSCHISTUS CRENATOR Fab. This species has become 
settled over a wide extent of territory, but it does not seem 
to have yet become very common in Lower California. It 
is common in Brazil, Central America, the West Indies 
and Mexico, and southern Arizona seems to be its most 
northern limit in the United States. 


PROXYS PUNCTULATUS Pal. Beauv. This species was 
collected at San José del Cabo, and Mr. John Xanthus 
secured a few specimens near Cape St. Lucas. It ap- 
pears to be more common in the warm parts of Mexico 
and it is not rare in southern Florida and the Antilles. 


HYMENARCYS 4 QUALIS Say. Specimens were in the 
collection of Mr. Henry Edwards, which were taken on 
some part of the peninsula not indicated. It has not been 
reported from Cape St. Lucas, and although found in 


230 CALIFORNIA ACADEMY OF SCIENCES. 


Mexico, it belongs rather to the highlands and more tem- 
perate parts of the country. 


LIoDERMA LIGATA Say. This species extends from 
Washington and Utah, all the way down the Pacific terri- 
tory to Cape St. Lucas. It is common in Arizona and 
southern California, from many parts of which I have 
examined specimens, as also from Mexico, as far south 
as into Sonora. 


LIoDERMA VIRIDICATA Uhler. I have examined speci- 
mens from the collection of Mr. Henry Edwards, which 
were collected in Lower California.

near Cape St. Lucas by Mr. John Xanthus. Specimens 
were found by Mr. C. D. Haines at Comondu, Cala- 
majuet, and on Margarita Island. 


PERIBALUS LIMBOLARIUS Stal. One specimen was 
captured in the vicinity of Cape St. Lucas by Mr. John 
Xanthus. It has been brought from other parts of the 
peninsula by several collectors. 


HoLcosTETHUS ABREVIATUS Uhler. A single speci- 
men from the peninsula was obtained from Mr. Henry 
Edwards. 


THYANTA PERDITOR Fab. This species lives on low 
weeds in barren grounds, and so we may expect to find 
it in most parts of Lower California. It is already known 
from Cape St. Lucas and from the northern part of 
the peninsula. It is common in Mexico, Arizona, Colo- 
rado, the Gulf States, Central America and the Antilles. 
In Hayti it lives on bushes and low weeds along the roads. 


THYANTA CUSTATOR Fab. This is the commonest and 
most variable species of the genus. It varies in size, as 
wellasincolor. By its adaptability to varieties of climate, 


HEMIPTERA OF LOWER CALIFORNIA. 231 


it has been able to hold its own in the province of Quebec, 
as readily as on the torrid sands of the region of Cape 
St. Lucas. It is almost everywhere to be found on the 
American continent where weeds can grow and low 
plants can secure a hold in the soil. 


THYANTA RUGULOSA Say. Several specimens of this 
small form were secured at Cape St. Lucas by Mr. John 
Xanthus. It seems to be local, as it has not been reported 
from many localities in California which are similar to 
others from which it has been taken. 


THYANTA CAsTA Stal. This species is common in Mex- 
ico, California, Arizona and New Mexico. It was taken 
at San José del Cabo by Dr. Gustav Eisen, and likewise 
from the vicinity of Cape St. Lucas by Mr. John Xan- 
thus. 


THYANTA PALLIDO-VIRENS Stal. This is a Mexican 
insect, which was collected at Cape St. Lucas by Mr. John 
Xanthus. 


CHLOROCORIS DEPRESSUS Fab. One specimen was se- 
cured at San José del Cabo by Dr. Gustav Eisen. 


CHLOROCORIS RUFISPINUS Stal. A few specimens were 
collected near Cape St. Lucas by Mr. John Xanthus. 


MURGANTIA HISTRIONICA Hahn. This extremely com- 
mon insect has spread into vegetable gardens, and may be 
expected to occur on most parts of the peninsula where 
man has settled. I have examined specimens from Cape 
St. Lucas, San José del Cabo, the island of Santa Cruz, 
of Guadaloupe, etc., and from many parts of Central 
America, Mexico, California, and from the western and 
southern States generally.

St. Lucas by Mr. John Xanthus. It is said to live on 
various species of the cactus family. 


MozENA AFFINIS Dallas. Specimens were taken at 
San José del Cabo by Dr. G. Eisen, and at Caperst: 
Lucas by Mr. John Xanthus. 


MozeENA LUNATA Burm. One specimen was found at 
Cape St. Lucas by Mr. John Xanthus. 


ARCHIMERUS CALCARATOR Fab. Specimens were taken 
near Cape St. Lucas by Mr. John Xanthus. This is a

to the temperate parts of North America. In the middle 
parts of the United States it occurs in most places where 
weeds and bushes grow thickly along the borders of 
woods. 


SAGOTYLUS CONFLUENTUS Say. This is a Mexican in- 
sect, which occurs sparingly in Arizona and California. 
Mr. Henry Edwards sent to me a specimen which was

his memoranda. 


Merrapopius GRANuLosus Dallas. This large and con- 
spicuous form is widely distributed, being found in Cen- 
tral America and extending north from Honduras to 
northern Arizona. Specimens were taken near Cape St

to the California Academy of Sciences there are three 
specimens labelled ‘‘ Texas.’’

this insect was collected near Cape St. Lucas by Mr. John 
Xanthus. Ithas also been taken in nearly all the southern 
and southwestern States, as well as in Mexico. 


LEPTOGLOSSUS STIGMA Herbst. A few individuals have 
been brought from the southern part of the peninsula by 
different collectors. It does not appear to be very com- 
mon in any one locality, although several specimens have 
been brought to my notice from Cuba. 


NARNIA FEMORATA Stal. Several specimens were 
taken at Comondu, in March, by Mr. Charles D. Haines. 
Others were secured at Cape St. Lucas by Mr. John

ern and Lower California are often of a paler color and 
much larger size than we have seenfrom any of the other 
regions where they are abundant. 


ANASA UHLERI Stal. A single specimen of this species 
was taken near Cape St. Lucas by Mr. John Xanthus.

black variety, with the pale ring at the apex of the fourth 
ea of the antennz, were taken at San José del Cabo by 

. Gustav Eisen. 


HypsELONoTUs FuLVUS DeGeer. One specimen and 
a larva was collected at Cape St. Lucas by Mr. John 
Xanthus. It isa common species in Mexico and Central 
America. 


SPHICTYRTUS BUGABENSIS Dist. Specimens of. this 
splendid species were collected at Cape St. Lucas, by 
Mr. John Xanthus, and I have examined others from 
Panama and Central America. I find the length of the 
rostrum to be quite inconstant in the specimens. In some 
it reaches to between the middle coxe, while in others it 
extends upon the second ventral segment. The extent of 
red upon the head, pronotum and scutellum is also very 
variable. It appears to me to be only a variety of S. 
sumtuosus Stal. The black color of the tergum of abdo- 
men is an evanescent element, depending upon the ma- 
turity of the specimen. The 5S. longirostris Dist., has a 
much longer rostrum, but it possesses no other permanent 
character to separate it from the 5S. bugabensis. More 
specimens are needed in order to settle the true identity 
of these so-called species. 


BURTINUS FEMORALIS Dist. Specimens were collected 


236 CALIFORNIA ACADEMY OF SCIENCES. 


near Cape St. Lucas by Mr. John Xanthus. <A specimen 
is in one of the bottles labelled San José del Cabo. This 
insect agrees so nearly with darker colored specimens of 
Burtinus notatipennis Stal, from Mexico, that I take it to 
be the same species. 


TIVARBUS DIVERSIPES Hope. One specimen is in the 
collection made by Dr. Gustav Eisen, at San José del 
Cabo. Others were secured at Cape St. Lucas by Mr. 
John Xanthus. It is a common Mexican species. 


To.Luius curTuLus Stal. This is a common insect in 
parts of southern California. A specimen was found 
near Cape St. Lucas by Mr. John Xanthus. 


LeEpTrocorIsa FILIFORMIS Fab. This widely distributed

species have been collected on various parts of the penin- 
sula. Mr. John Xanthus sent forward a considerable 
number from the vicinity of Cape St. Lucas. 


HARMOSTES SERRATUS Fab. This species has not been 
found in numbers in any part of California. I have ex- 
amined a single specimen from Cape St. Lucas. 


CorRIZUS HYALINUS Fab. This European insect swarms 


HEMIPTERA OF LOWER CALIFORNIA. 237; 


in many parts of California, Arizona, New Mexico and 
Colorado. I have seen many specimens from various 
parts of Lower California. It was taken on’ Margarita 
Island and at San Julio by Mr. C. D. Haines. 


Corizus sipa@ Fab. <A few specimens were collected 
near Cape St. Lucas by Mr. John Xanthus. Others were 
secured at Patrocinio, Comondu and Calmalli mines by 
Mr. C. D. Haines. 


CoRIZUS LATERALIS Say. Common in various parts of 
California. Specimens were taken at Cape St. Lucas by 
Mr. John Xanthus; and at San Julio, in April, by Mr. 
C. D.: Haines. 


CORIZUS NIGRISTERNUM Signoret. Common in south 
ern California and Arizona. Specimens from Lower Cali- 
fornia were sent to me by Mr. Henry Edwards. 


Corizus vatipus Uhler. One specimen was taken at 
San José del Cabo by Dr. Gustav Eisen. 


CORIZUS PUNCTIVENTRIS Dallas. A few specimens of 
this species were collected near Cape St. Lucas by Mr. 
John Xanthus. 


Corizus new sp.? A specimen too poor to describe is 
in the collection from San José del Cabo. It seems to 
be closely related to C. punctiventris Dallas. 


Leprocoris TRIvITTATus Say. This species inhabits 
most parts of lowland California, and is common in Ari- 
zona, New Mexico and on the plains of Colorado, as far 
north as Denver. Mr. John Xanthus captured specimens 
of it near Cape St. Lucas. 


JADERA H&MATOLOMA H, Schf. This is a subtropical 
species which inhabits Central America, Mexico, the 
West Indies, Texas and southern Florida. Specimens of 
it were taken at Cape St. Lucas by Mr. John Xanthus. 


238 CALIFORNIA ACADEMY OF SCIENCES. 


BERYTIDA. 


NEIDES MuTICUS Say. This very slender species in- 
habits many parts of the region near the coast of the 
Pacific Ocean. Mr. John Xanthus secured specimens of 
it near Cape St. Lucas. As this is is a highland species 
which extends north into British Columbia, it is inferred 
that it was found in the mountains inland from Cape St. 
Lucas. 


ACANTHOLZNA ANNULATA Uhler. This neat little 
species was found at San Borgia, in May, by Mr. C. D. 
Haines. Collections made in the early summer would, 


no doubt, add other tropical species to those already rec- 
ognized, especially among the forms which inhabit damp 
places and the fresh or brackish waters. 


LYGAIDZA. 


\ 


Nysius CALIFORNIcUS Stal. The specific name here 
given is unfortunate, for this insect inhabits all the herba- 
ceous regions from Central America to British Columbia, 
and from New Jersey to Florida and Cuba. Specimens 
were secured by Mr. John Xanthus at Cape St. Lucas. 


Nysius ancustatus Uhler. Specimens of this small 
insect were collected by Mr. John Xanthus, near Cape St. 
Lucas, and others were found at San Jorge, in March, 
by Mr. C. D: Haines.

of North America. It occurs in Massachusetts and ex- 
tends from thence to Florida. On the western side it is 
found in Colorado, near Denver, and from that point 
southwest, at various stations, to Arizona, California and 
Lower California. It was also collected at El Paraiso by 
Dr. Gustav Eisen.

lateral margins of the posterior lobe of the pronotum and 
sometimes the posterior part of the medial carinate line 
red. Head moderately long, subacute, minutely and obso- 
letely scabrous, very minutely pubescent; antennz stout. 
finely pubescent, the second joint long, about equal to the 
fourth, the third short and a little longer than the basal 
joint; rostrum reaching the posterior coxe. Pronotum 
depressed behind the collum, and back of the curved im- 
pressed line between the lobes, the callosities almost ob- 
solete, the lateral margins prominently elevated and grow-

pronotum, 2—3 mm. 

This species closely resembles Lygeus lateralis Dal- 
las, as figured by Mr. Distant in the Biologia Cent. Amer., 
plate 18, fig. r. But the figure seems to give a much 
narrower insect with longer head, corium bordered with 
red, and joints of antenne relatively longer. 

Numerous specimens were collected at Cape St. Lucas 
by Mr. John Xanthus. Another was secured at San 
José del Cabo by Dr. Gustav Eisen.

Lyczus cosTaLtis H. Schf. Specimens have been 
brought in from nearly every part of Lower California. 
It was collected at San José del Cabo by Dr. Gustav 
Eisen, and at Comondu, Calmalli mines and San Jorge, 
in March and April, by Mr. Charles D. Haines. 


Lycaus tTurcicus Fab. <A few specimens of this 
form were included ina large bottle of Z. reclivatus Say, 
which were collected near Cape St. Lucas by Mr. John 
Xanthus. These two so-called species are but forms of 
a true single species for which the name Lygeus turcicus 
Fab. has priority. It is convenient, however, to label 
them with the two names in our cabinets, since the west- 
ern one is generally marked with the two white dots on 
the membrane, while in the eastern form the two white 
dots are usually absent. We now possess series from 
both sides of the continent, taken from a single brood, 
which not only include these two varieties, but others, to 
which European entomologists have given other names. 
That very wise closet naturalist, M. Montandon, insists 
upon- keeping the species separate, because one or two 
specimens that I sent to him have the red color of the 
head widely spread, instead of being confined to the mid- 
dle of the vertex. The pattern of marking and spread 
or depth of color in specimens of this insect are extremely 
variable, and not one-half of the varieties of either col-

ors or form have yet been published. It is interesting to 
record that melanism is quite common in specimens from 
Washington State, and that I have seen a few from Van- 
couver in which the two white spots were exceptionally 
large and convergent on the inner sides. 


ONcCoPELTus FAsciATus Dallas. Specimens were col- 
lected at San José del Cabo and other stations by Dr. 
Gustav Eisen, and Mr. Charles D. Haines found it at the

D. Haines. Mr. John Xanthus collected many specimens 
of it near Cape St. Lucas.

756, 777 and 554. The males are very much narrower 
than the females, and this gives greater apparent ampli- 
tude to the wing-covers. Immature varieties have much 
of the black color above substituted by a pale lead-color, 
and the legs more or less fulvous or testaceous. Two 
specimens were taken at San José de Gracias.

NEUROCOLPUS NUBILUS Say. Syn. JV. mexicanus Dist 
One specimen was taken at Cape St. Lucas by Mr. 
John Xanthus. A single specimen in the collection of 
the California Academy of Sciences is marked ‘‘Cal. 9.”’ 

This species is one of the most variable of the incon- 
stant Phytocoraria. It is distributed all over the North 
American continent from Quebec to Panama, and it seems 
to be about as variable in Mexico as it is in Maine or 
Maryland. As I have compared specimens with Mr. 
Distant’s types, I find them to be precisely like varieties 
of LV. nubslus Say, which I have collected with my own 
hands, and some of which I have raised from the newly 
excluded condition to the fully matured state. A per- 
manent variety has the posterior femora dark gray, with 
a small pale spot on the upper side. The other extreme 
of color has the hind femora yellowish or fulvous, with 
the apex broadly black. ‘The basal joint of the antenne 
is also variable in thickness. In some specimens the tip 
of this joint is knobbed and smooth. 


CALOCORIS SUPERBUS Uhler. 
This common species occurs near Cape St. Lucas, as 
well as in Mexico and the western United States. 


CALOCORIS RUBRINERVE Dist. This is a common spe- 
cies in Mexico, southern Florida, Texas and the Lesser 
Antilles. Specimens were found at Lower Purisima in 
April, and on Margarita Island in March, by Mr. C. D. 
Haines.

placed nearly vertical, vertex broadly grooved on the 
middle, transversely impressed between the upper corners 
of the eyes; the front tumid, subpentagonal, nearly flat 
on the middle, the outline strongly curved when viewed 
from the side; the sockets of the antennz seated in a cav- 
ity. Antenne long and slender, the basal joint longer 
than the pronotum, the second longest, as long as the 
clavus, the third not much more than half as long, the 
fourth more slender and a little shorter than the third. 
Rostrum slender, pale greenish, dusky at tip, reaching 
behind the middle of venter. Pronotum wider than long, 
paler anteriorly, the collum prominent, confined to the 
width between the eyes, callosities oval, low, tinged with 
reddish-brown, the posterior margin broadly curved, a 
little uneven, with the humeral angles a little reflexed and 
the adjoining surface indented; the surface uneven around 
the callosities, pale pubescent near the sides, the lateral 
margin not distinctly carinated, very slightly sinuated; 
lower margin of pleural flaps pale, reflexed. Chest and 
venter greenish-white, silky pubescent. Legs yellowish, 
the femora a little dusky near the tip, with the nails black. 
Scutellum green, a little convex, sometimes red at base, 
with the tip acute, Corium pubescent, either entirely, 
green or bordered with red inwardly, the costal margin 
pale yellowish-green; the clavus red or reddish-brown, 
sometimes clear green; cuneus green, occasionally bor- 
dered inwardly with red; membrane fuliginous with the 
vein darker. Tergum more or less rufous. 

Length to tip of venter, 5-5% mm. Width of prono- 
tum, 134-2 mm. 

A tew specimens of this beautiful form were collected 
at San José del Cabo by Dr. Gustav Eisen. As the al- 
cohol in which these specimens were placed had disin- 
tegrated them for the most part, the study of their legs 
and antenne had to be derived from detached members.

face irregularly and deeply punctate, having a large sub- 
quadrate black spot anteriorly which includes the convex 
callosities, the transverse impression deep, sunken in the 
middle; collum narrow, deeply contracted, marked with 
a small black knob in the middle; lateral carina very 
slender, pale, slightly sinuated posteriorly, a little reflexed

at the sutures, minutely shagreened, the apical seg- 
ments set with erect hairs. 

Length to tip of venter, 5-6 mm. Width of prono- 
tum, 2-214 mm. 

Only three specimens of this insect have thus far 
been brought to my notice. They are all females, and 
differ in the depth of color and amount of marking 
upon the upper and under surfaces. One specimen 
was taken near Cape St. Lucas by Mr. John Xanthus, 
a second was found in southern Texas by Mr. Andrew 
Bolter and the third was secured in York County, Pa., 
by Droit. Ee. Melsheimer: 

The insects of this genus occur on the branches and 
twigs of young pine trees in early summer; and it is 
likely that this new species will be found in moderate 
numbers when attention is paid to collecting from the 
young pine trees. The male is now adesideratum. The 
tibia of this species are sometimes marked with three 
whitish incomplete bands. 


LycGus sALLEI Stal. This is a common species which 
includes several varieties. It has been found in Texas, 
Colorado, Arizona, California and in Mexico, as far south 
as Orizaba. One or two damaged specimens are in the 
collection from San José del Cabo. Several specimens 
anedabeled *¢Calt’’ 


Lycus PRATENSIS Fab. This species has been widely 
dispersed through the agency of commerce. It is found 
at the seaports of every part of North America, on the

west as well the east; and it is now distributed over the 
whole width of the continent from the mouth of Macken- 
zie River in Arctic America to Panama and northern Bra- 
zil. It dwells on weeds and grasses of many kinds. Mr. 
John Xanthus brought specimens from Cape St. Lucas, 
and in the present collection there are specimens labeled 
“Calvers and“ Cal-.o.,

the callosities slightly carinate across the front, the collum 
cylindrico-convex, almost in contact with the corner of 
the eye, lateral margins steep, the carinate edge almost 
obliterated, the surface generally clothed with yellow, 
almost erect, pubescence, and obsoletely scabrous. Scutel- 
lum longer than wide, pubescent and scabrous like the 
pronotum, moderately convex, yellow across the depressed 
base. Hemielytra densely minutely scabrous, closely pu- 
bescent, with the broad almost straight costa pale green-

HEMIPTERA OF LOWER CALIFORNIA. 261 


A single male from Comondu (No. 318) was obtained 
by Mr. C. D. Haines, ‘in March, 1889. The only other 
specimens that I have examined were collected in south- 
ern California; they were, however, too much damaged 
to afford characters for description. This type of struct- 
ure is exceptional in the genus Lygus, and when speci- 
mens of both sexes can be obtained for dissection, it is 
possible that this species will have to be transferred to an- 
other genus. It has several characteristics which recall 
relationship with the genus Orthotylus. 


Lycus sp.? Fragments of four other species, appar- 
ently undescribed, are known from Cape St. Lucas and 
other parts of Lower California, but they do not afford 
sufficient materials for description. 


ORTHOPS SCUTELLATUS Uhler. Specimens were col- 
lected near Cape St. Lucas by Mr. John Xanthus. The 
species is distributed over many parts of the West, in- 
cluding California, Arizona, Colorado, Ilinois, Minnesota 
and Canada. 


PacILoscyTus BASALIs Reuter. This species occurs 
on small plants in various parts of California, Arizona. 
Texas and Colorado, as well as in most parts of the east- 
ern United States. A few specimens were collected near 
Cape St. Lucas by Mr. John Xanthus. In the present 
collection there are specimens from California. 


Pa:CILOSCYTUS INTERMEDIUS n. sp. 

A little more robust than P. basal/s Reuter, with stout- 
er antenne ; oval, pale brownish-yellow or chestnut-brown. 
minutely pubescent. Head a little oblique, highly pol- 
ished, luteous, with a black circle on the face between 
the eyes which is interrupted below, but carried back 
posteriorly to the base of the head, below this the tylus 
is deep black, except at base; cheeks below the anten-

ne bright yellow, highly polished, swollen; front set with 
erect yellowish hairs; occipital carina narrow, dull yel- 
low, black in the middle; rostrum slender, piceous at 
base and tip, reaching between the middle coxe. Pro- 
notum convex, dark brown, bronze pubescent, often bor- 
dered posteriorly with yellow, and with an oblong dull 
yellow spot on the middle, collum more or less dull yel- 
low, the surface scabrous and transversely wrinkled, the 
posterior margin regularly curved. Scutellum dark brown, 
pubescent, wrinkled, broadly yellow at tip. Legs dull 
yellowish, the two anterior pairs of femora paler, crossed 
by about two piceous bands, the posterior femora crossed 
by broader and darker bands, tibial knees and apex of 
tarsi blackish piceous. Hemielytra pale dull tawny or 
obscure chestnut-brown, with the costal margin and cu- 
neus pale yellow, the base of corium shaded and streaked 
with pale dull yellow, the coarse vein of inner apical mar- 
gin next behind the clavus conspicuously yellow; the sur- 
face mostly covered with prostrate bronze-yellow pubes- 
cence; membrane dusky, with the veins yellow. Ster- 
nal and pleural pieces black above and between the coxa, 
elsewhere yellow. Venter yellow, with a black disk and 
an interrupted black stripe next the connexivum. In the 
male the black color is sometimes spread over most of the 
venter. 

The antenne are longer and stouter than in P. basalzs 
Reuter, and the second joint is as long as the corium. 

Length to end of venter,é64; 25%-6 mm. Width of 
pronotum, 2—2% mm. 

A specimen, 4, is in the collection from San Quintin 
CNo. 814), collected in May by Mr. C.D. Haines, and 
others are marked ‘‘Cal. 9.’’ The species inhabits many 
parts of California, and it is found also in Arizona. No. 
813 from El Rosario, collected in May by Mr. C. D. 
Haines, is a faded variety of the same species.

on it and another above it, collum narrow but clearly de- 
fined, bounded before and behind by a slender brown 
margin, on the middle behind the callosities are two round, 
brown dots, humeral angles more projecting than the lat- 
eral margin, the posterior margin a very little curved, but 
bending down towards the scutellum; pleural flaps quite 
narrow, scabrous. Legs yellow, the femora flecked with

Length to tip of abdomen, ¢, 44%; ¢%, 434-5 mm. 
Width of pronotum, 2-2% mm. 

This beautiful little species was found at San José del 
Cabo by Dr. Gustav Eisen. Fragments of specimens 
from Texas and Maryland have been for a long time in 
my collection, but not in condition for identification. It 
mimics in markings of thorax, and somewhat in figure, 
certain varieties of Phytocoride related to P. colon Say. 


NeEosporus SAXEuS Dist. Specimens in this collection 
are marked ‘‘Cal. 9.’’ A specimen more closely resem- 
bling the variety described by Mr. Distant was taken by 
Mr. John Xanthus near Cape St. Lucas. This insect 
presents all the varieties of color and marking possible to 
its plan of development. It is met with entirely of a yel- 
lowish-white, then nearly all black, others are greenish- 
yellow with a black face and mostly black pronotum and 
clavus, and with a large black spot near the apex of each 
corium; these markings are sometimes replaced by brown, 
purplish, or rosy red. Another variety has the face 
marked with crimson, four stripes of the same color on 
the pronotum, and the clavus and large spots of the cori- 
um also crimson. 

It is sometimes very common in Maryland and the Dis- 
trict of Columbia on the linden tree. It occurs as far 
north as the central part of Maine. 


HEMIPTERA OF LOWER CALIFORNIA. 265 


CAMPTOBROCHIS NEBULOSUS Uhler. ‘Two specimens 
are in’ the: collection; marked ““Cal. 4.7’ A few speci- 
mens were found near Cape St. Lucas by Mr. John 
Xanthus. This species is now known from most parts 
of North America. It is distributed from Quebec to 
northern Florida, and on the Pacific side of the continent 
it has been found in British Columbia, Washington State, 
and from thence to San Bernardino, California, and far- 
ther south. 


DERZOCORIS CERACHATES DN. sp.

orange, tipped with clear brown; membrane pale smoky 
with the veins yellow at base and brown at tip. Venter 
ruto-fulvous, with an arcuated dark brown band before 
the middle. 

Length to tip of venter, 5-5% mm. Width of prono- 
tum, 24-234 mm. 

This species is not rare at Los Angeles and various 
parts of southern California. A single specimen ( ) of 
the large variety was secured at San José del Cabo by 
Dr. Gustav Eisen. 


THYRILLUS gen. nov. 

General aspect of Rhopalotomus; hairy, head thick, 
nearly vertical, the face prominently tumido-convex, the 
throat swollen, the eyes projecting laterally and superi-

acuminate at tip. The costal border strongly and sharply 
recurved at base and sunken on the submargin. Cuneus 
depressed, the inner border at base thickened. Legs 
long. 


HEMIPTERA OF LOWER CALIFORNIA. 267 


TuyRILLus paciFicus Uhler.. The specimens. in this 
collection are labeled ‘‘ Cal. 9.”’ A few broken speci- 
mens from Lower California were given to me by Mr. 
Henry Edwards. This species seems to be fairly com- 
mon at Los Angeles, San Bernardino and in the neigh- 
borhood of San Francisco. I have also seen a few speci- 
mens from southern Nevada, and others from Yakima, 
Washington. 


THYRILLUS BRACHYCERUS Uhler. This is also a com- 
mon insect in various parts of California. One speci- 
men is in the bottle labeled San José del Cabo, and it 
was collected by Dr. Gustav Eisen. Other specimens 
in the collection are labeled ‘‘Cal. 9.’’ Both of these 
species were placed in the genus Rhopalotomus when 
first described, but they seem to constitute a new genus, 
tor which the above name is proposed. 


PYCNODERES QUADRIMACULATUS Guerin. This is a 
common insect which inhabits sandy localities on both 
sides of the North American continent south of the lat- 
itude of New Hampshire on the east, and probably of 
San Francisco on the west. It occurs, also, in Cuba 
and other islands of the West Indies. A single specimen 
was taken near Cape St. Lucas by Mr. John Xanthus. 


CyRTOCAPSUS CALIGINEUS Stal. One specimen was 
taken near Cape St. Lucas by Mr. John Xanthus. The 
species is widely distributed in California, and it appears 
to be moderately common in the vicinity of San Fran- 
cisco. 


MALACOCORIS IRRORATUS Say. A soiled and damaged 
specimen (No. 755) of this common insect is in the col- 
lection which was made at Calmalli mines, in April, by 
Mr. Charles D. Haines. 


268 CALIFORNIA ACADEMY OF SCIENCES. 


ILNACORA CHLORIS Uhler. Formerly placed in the 
genus Sthenarops Uhler, which genus is now seen to be 
preoccupied by IInacora Reuter. It is No. 744 of the 
collection from San Julio, and it was secured in April by 
Mr. Charles D. Haines. 


LABoPIDEA CHLORIZA Uhler. An unusual variety of 
this species (No. 665) was found at San Esteban, in 
April, by Mr. Charles D. Haines. Most likely this spec- 
imen was found in the highlands of the region, since the 
species has previously been known from the mountains 
and hills of Washington State and remote northern parts 
of the northwest. 


STIPHROSOMA ATRATA DN. sp. 

This species is closely related to S. stygica Say, deep 
black, polished, closely and mostly roughly punctate; 
base of head not so strongly grooved as in the species of 
Say, the antenna are more slender, deep black, except- 
ing only the immediate points of articulation, which are 
indistinctly pale; the legs are black, excepting only the 
very tip of femora and the base of tarsi, which are testa- 
ceous, and the membrane is smoke-black, with the base 
next the cuneus narrowly whitish. 

Length to tip of venter, 3-3% mm. Width of prono- 
tum, 134-2 mm. 

Several specimens were collected at San Julio, in 
April, by Mr. Charles D. Haines. It is common in many 
parts of southern California, notably at Los Angeles and 
near San Bernardino. 


MAcCROCOLEUS COAGULATUS Uhler. Specimens were 
secured at the Calmalli mines and at San Julio and El 
Paraiso, in April and May, by Mr. Charles D. Haines. 
This is a widely distributed western and northern form.

Lucas by Mr. John Xanthus. It is quite desirable to 
have series of these insects, since the full characters of 
the species cannot be well Known until both sexes have 
been carefully examined, 

FULVIUS ANTHOCOROIDES Uhler. Specimens have been 
brought from Los Angeles and San Bernardino, and from 
Cape St. Lucas by Mr. John Xanthus. This species is 
now Known trom many places on both sides of North 
America. Itis also found in the West Indies, Central 
America and Mexico. 

CLOSTEROCORIS ORNATUS Uhler. This is a common 
species in many parts of California and Arizona. Two 
specimens were secured at San Quintin, in May, by Mr. 
C.D, Haines. Others are labeled’ ““ Monterey (Co. Gale 
M. K. Curran.’* Other specimens are labeled. **:Caltea

DicypHus CALIFORNICUS Stal. Numerous specimens 
are in the collection, and from various localities. A se- 
ries is labeled ‘‘ Cal. 2 and Cal. 9.’’ One or two speci- 
mens were in the bottles from San José del Cabo, collect- 
ed by Dr. Gustav Eisen. It was found also near Cape 
St. Lucas by Mr. John Xanthus. 

ENGYTATUS GENICULATUS Reuter. Several damaged 
and faded specimens are in the collection (numbers 69 
and 317). They were taken at Comondu and on Mag- 
dalena Island, in March, by Mr. C. D. Haines. This 
species is common, and is now seen to be very widely 
distributed in the Southern States, Mexico and the West 
Indies. 

RHINACLOA FORTICORNIS Reuter. Specimens were 
secured at San Julio and on Margarita Island in March 
and April, by Mr. C. D. Maines (Nos. 54 and 749). It 


is a common insect in the Southwestern States. 


HEMIPTERA OF LOWER CALIFORNIA. 275 


AGALLIASTES DECOLOR Uhler. Two specimens of this 


inconspicuous little species were collected near Cape St. 
Lucas by Mr. John Xanthus. 


PsaLLus pDELICATUS Uhler. Several specimens were 
collected at the Calmalli mines in April by Mr. C. D. 
Haines. 


PSALLUS BIGUTTULATUS N. sp. 

Yellowish-white, milk-white on the membrane, with 
two small angular black spots on its exterior border; the 
surface finely pubescent. Head subtriangular as seen 
from above, smooth, yellow, moderately convex, directed 
obliquely, the eyes long, brown, placed almost vertically; 
the tylus parallel-sided, a little curved; antenne short, 
slender, black, the basal joint short, white, with a sub- 
apical band and exterior stripe black; rostrum testaceous, 
tinged with fulvous, reaching between the intermediate 
coxe. Pronotum wider than long, moderately convex, 
the lateral margin sinuated, reflexed, the anterior margin 
very delicately reflexed and notched in the middle, the 
outer border of the callosities posteriorly with an indented 
line, humeral angles subacute, a little granulated, bor- 
dered inwardly by a depression, the posterior margin 
almost straight. Scutellum almost flat, a little punctate, 
and obsoletely carinate on the middle line. Legs whitish-

PsALLUS GUTTULOSUS Reuter. One specimen, No. 804, 
was taken at San Fernando in May by Mr. C. D. Haines. 


PSALLUS O: Sper 

Two specimens, No. 307, from Comondu, March, were 
collected by Mr: C: ). Haines: Theiconditiony or itine 
insects would give only misleading characters for descrip- 
tion. 

Several other species related to Psallus are in the col- 
lection from Lower California, but they do not furnish 
proper material for description. 

A most interesting and peculiar type of Capsid, related 
to Pilophorus, is in the collection and labeled ‘‘ Cal. 9.”’ 
It seems important to add a description of it in this arti- 
cle, since the same insect, or one much like it, was col- 
lected in Lower California by Mr. John Xanthus. 


MyRMECOPSIS Nn. gen. 

In form much resembling the common black Formica 
which inhabits the wood of trees in the eastern United 
States. Head long, thick, almost vertical, much thicker 
than the swollen middle of the pronotum; the front con- 
tinuous with the vertex, and both occupied by a broad 
ridge down the middle, which grows obsolete below the 
line of the antenne, the tumid head growing narrower 
behind the eyes and ending in a short and much contracted 
neck, the face wide to the base of the tylus, conical be- 
low that line; eyes large, placed nearly vertical, promi- 
nent above and laterally; antenniferous basal support 
starting slender below the middle of the eye and project- 
ing to near the lower line of the eye; the basal joint of 
antenna reaching almost to the tip of the tylus, the sec- 
ond joint clavate towards the tip, as long as from the 
middle of the eye to the base of pronotum, the third joint 
abruptly slender, about half as long as the second; ros- 


HEMIPTERA OF LOWER CALIFORNIA. 27

and scarcely extending beyond the middle of the throat, 
remaining joints very slender, not extending beyond the 
posterior coxe; the throat deep and the upper cheeks 
long and triangular. Pronotum curved upwards, sub- 
cylindrical, but swollen on the middle and much contracted 
behind this swelling, the middle of posterior margin very 
prominently reflexed-folded, so as to leave an acute notch 
there, surmounted by a thick spine. Hemielytra begin- 
ning very narrow, gradually widening posteriorly and 
finishing in a bluntly rounded tip, coriaceous, closely 
pubescent, with the basal vein gradually spreading away 
from the costal as it proceeds backwards. Legs long and 
rather stout. The abdomen inflated beyond the con- 
tracted base. 


MyRMECOPSIS INFLATUS 0. sp. 

Formiciform, piceous-black, dull, not apparently punc- 
tate. Head long and thick, subconical at lower end; 
antenne rufo-fulvous, blackish on the apical third of the 
second joint. Rostrum reaching to the posterior coxe, 
piceous at base and tip. Pronotum blackish-piceous, 
tinged with rufo-castaneous beneath and in front, medial 
hump curving diagonally upwards and forwards, the de- 
pression behind it deep and the flexure of the posterior 
border almost abrupt, the posterior edge white, with the 
spine black. Legs dull rufo-castaneous, with the femora 
somewhat darker. Hemielytra velvety blackish-brown, 
pale lead-color at base and along the inner border, the 
membrane pale, with an ivory-yellow border at base. 
Venter piceous-black, with a large angular white patch at 
base. 

Length to end of venter 6 mm. Width of base of pro- 
notum I mm. 

This wonderful insect deserves to be studied to dis-

cover its habits. That it should be so much.like an ant 
without requiring the protection suggested by such mim- 
icry is well worthy of ardent attention. 


ACANTHIID. 


ANTHOCORIS ANTEVOLENS B. White. Afew specimens 
were secured at Cape St. Lucas by Mr. John Xanthus. 
It is in the collection from some other part of California, 
but it is a widely-distributed form which is known from 
various parts of Arizona, Mexico and southern California. 

TRIPHLEPS TRISTICOLOR B. White. Several specimens 
were collected at the Calmalli mines and on Margarita 
Island in March and April by Mr. C. D. Haines. No. 
742, three specimens from San Quintin, are too much 
deformed to be recognizable. 


ACANTHIA LECTULARIA Linn. The common bed-bug 
is distributed in Lower California as actually as it is in 
Mexico and California farther north. 

TINGITID A. 


PIESMA CINEREA Say. One specimen from Lower 
California received from Mr. Henry Edwards. The 
species is found also at Los Angeles, in the vicinity of 
San Bernardino, and in California farther north, besides 
the United States generally. 


TELEONEMIA SACCHARI Fab. Specimens were taken 
at San Jorge in March by Mr. C. D. Haines. 


GARGAPHIA OPACULA Uhler. A few specimens were 
secured at San Luis and on Magdalena Island in March 
and April by Mr. C. D. Haines. 


CoRYTHUCA FUSCIGERA Stal. This species is distrib- 
uted over most parts of California and Mexico. Speci- 
mens were taken at Cape St. Lucas by Mr. John Xan- 
thus.

Comondu, in March, and another at San Luis, in April, 
by Mr. C. D. Haines. 


CoORYTHUCA HISPIDA N. sp. 

Dull white, with the eyes and body black, the antennz 
a little lurid yellow, and darker at tip. Pronotal hood 
long, tapering rapidly toward the front, with comparative- 
ly long spines all over, pointing in all directions, provided 
with mostly circular small cells, the anterior division sep- 
arated from the globose base by an abrupt constriction; 
the lateral lamellae bean-shaped, mostly opaque, but with 
small circular cells, separated anteriorly from the hood 
by a narrow triangular space, the surface and particular- 
ly the margins armed with mostly close-set spines. Scu- 
tellum with the medial carina low, armed with spines 
pointing outwards from both sides, as is the case with the 
reflexed outer margins. Hemielytra comparatively nar- 
row, with three rows of circular variable cells between 
the discoidal flexed carina and the outer border, the cos- 
tal margin set with long straight spines which decrease in 
length near the tip, these continue to within three cells of 
the tip; discoidal carinate bulla low, spread with about 
four rows of almost quadrangular cells. Legs fulvo- 
testaceous. 

Length to apex of hemielytra, 234-3 mm. Width

pressed and narrow anteriorly, not high, carrying about 
three series of cells, anterior part of carinate ridge with 
erect spines, sides with shorter spines, the posterior glob- 
ular portion not much wider than the division next in 
front of it; lateral lamella almost triangularly narrowed 
anteriorly, reaching forward almost as far as the tip of 
the hood, areoles small, arranged in four series, margin- 
ed along the full length with straight, long, nearly equi- 
distant spines, the posterior margin not far from the front 
border of the hemielytra. Base of mesonotum like a 
transverse, interrupted collar, with the middle between 
the swellings longitudinally carinate, the space each side 
of this, the hollows at base of hood, the center of bulla 
on the disk of hemielytra, and the veins of the marginal 
cells black. Scutellum almost flat, with the middle car- 
ina thicker than the marginal ones. Hemielytra a little 
wider behind, somewhat bent outwards, with six rows of 
chiefly quadrangular cells; the base a little wider than 
the lamella, deeply notched in the middle, armed with 
spines which gradually decrease in size until arrested at 
about one-third from the tip. Legs, rostrum, buccule, 
and sternal carinate pieces testaceous. Venter a little 
rufo-fulvous on the middle. 

Length to tip of hemielytra, 3% mm. Width of pro- 
notal lamella, 17% mm. 

Specimens in this collection are labeled ‘*S. Cal.”’ 

I have examined one specimen from Cape St. Lucas. 

This species comes near C’. decens Stal in appearance, 
but it has more of the form of C. fusczgera Stal, and dif- 
fers from both in the characters given above. 


CoRYTHUCA INCURVATA DN. sp.

hexagonal, above stained with dark brown; lateral lam- 
ella short, sunken and with a brown spot anteriorly, bent 
upwards posteriorly, the edge with very short, close set 
spines. Scutellum simple at base and brown there, the 
carinate middle line high, with a brownish spot each side. 
Hemielytra with large, mostly subquadrangular areoles, 
the outer border deeply sinuated, the costal row of cells 
stopped at one-third from the tip, and the very minute 
spines hardly extending that far, base feebly notched; 
the inner margin, a band before the apex, and the bullate 
portion of the disk brown. Antenne, excepting the dark 
apical joint, the rostrum, bucculw, and legs testaceous. 
Apical third of the venter rufous. 

Length to tip of hemielytra, 3 mm. Width of pronotal 
lamellae, 1% mm. 

This species is labeled in the collection ‘*Cal. 7.”’ 

It is, however, an inhabitant of Lower California, Mex- 
ico and Arizona.

taken at Cape St. Lucas and in Mexico. 


BRACHYRHYNCHUS EMARGINATUS Say. Specimens 
were collected at San José del Cabo, by Dr. G. Eisen; 
and near Cape St. Lucas, by Mr. John Xanthus. 


282 CALIFORNIA ACADEMY OF SCIENCES. 


PHYMATIDZ. 


Puymata Fasciata G. R. Gray. P. Wolffid Stal. 
(syn.) This species is now distributed over the greater 
part of North America. Doubtless it has been distrib- 
uted by hurricanes and less violent storms of wind from 
region to region, and through the distribution of garden 
plants by commerce it has unquestionably been transport- 
ed to distant localities. At length it may be expected to 
occur wherever roses and herbaceous garden plants shall 
be carried from North America. 

Specimens were collected on Magdalena Island, also 
in Siskiyou County and in southern California. 

In the eastern United States as well as in Colorado, 
Kansas, etc., it enters between the florets of the golden 
rod and the heads of other flowers, where it matches the 
pollen-spread surfaces, and seizes the unwary insects 
which come within its reach. 


REDUVIOIDEA. 


Coriscus FERUS Linn. This species is dispersed 
throughout almost every region of North America. It is 
found in Lower California, as well as in Arizona, Cal- 
ifornia and New Mexico.

the collection were taken at the Calmalli mines, San Luis, 
San Esteban in April, and on Margarita Island in March, 
by Mr. C.D Haines. 


SINEA UNDULATA DN. sp. 

Brownish-cinereous, pale gray, pubescent, similar to 
S. diadema Fab., but wider, with a shorter neck and fe- 
mora, with the spines more numerous and crowded to- 
gether on the front division of the head, with the carinate 
‘ines of the middle of pronotum prominent and sharply 


HEMIPTERA OF LOWER CALIFORNIA. 283 


defined, and the knobs each side of base elevated, and 
surmounted by a little tubercle; three double series of 
spine-like, black tubercles on the anterior lobe of the pro- 
notum. Venter with a series of oblique, white spots on 
each side near the border; scallops of the lateral border 
more prominent and placed further back than in S. déa- 
dema; the inner margin of corium white. 

Length to tip of venter, 14-15 mm. Width of prono- 
tum, 3 mm. 

This appears to be a common species in southern Cal- 
ifornia and in Lower California. Specimens were col- 
lected at San José del Cabo, and at the Calmalli mines by 
Mir C.D. Haines. 


PRIONIDUS CRISTATUS Linn. One or two specimens

differs from all species known to me by having the outer 
edge of the connexivum thickened, not sharp-edged, as 
is common to the large Mexican forms. 


STENOPODA CULICIFORMIS Fab. Specimens were cap- 
tured at Cape St. Lucas by Mr. John Xanthus. 


Emesa LoncipEes DeGeer. Several specimens of this 
insect were secured at San José del Cabo by Dr. Gustav

GALGULID&. 


GALGULUS OCULATUS Fab. Numerous specimens have 
been brought from Cape St. Lucas; and the insect is in 
one of the bottles from San José del Cabo, collected by 
Dr. Gustav Eisen. This insect inhabits nearly the whole 
continent of North America. How such a clumsy and 
merely leaping insect could become distributed so gen- 
erally, beyond mountain ranges and at various altitudes, 
from the tropics to the Laurentian hills, is a mystery not 
easy to solve. 


GALGULUS VARIEGATUS Guerin. A few species of this 
silver-spangled form are included with the others from 
Lower California. This does not seem to me as a good 
species. It is more clearly marked and a cleaner insect 
than the other, but there are varieties which very nearly 
connect the extremes of color and marking. 


Mononyx sTycGicus Say. One specimen was taken 
near Cape St. Lucas by Mr. John Xanthus; others were 
secured at San José del Cabo by Dr. Gustav Eisen, also 
at El] Paraiso. On the eastern side of the continent its

reported from as far north as San Francisco.

AMBRYSUS PUDICUS Stal. Specimens were collected at 
San José del Cabo by Dr. Gustav Eisen. It occurs also 
at Los Angeles and San Bernardino. 


PELOCORIS FEMORATA Pal. Beauv. This widely dis- 
tributed species was taken at San Ramundo and at San

on both sides of the continent, from Canada to Florida, 
and from thence into the Antilles and Mexico.

carinated on the middle, the occiput bordered with a 
thick carinate edge; the inner submargin of the eyes 
marked by a line of punctures which terminate in a group 
set in an oval fossa near the lower end of the eye; the 
clypeus distinctly, obliquely depressed each side of the

the basal margin of the eyes almost truncate; the apical 
joint of rostrum dark piceous. Pronotum obsoletely im- 
pressed across the middle, transversely indented behind 
the vertex and remotely punctate there, behind this the 
surface is more or less wrinkled; the lateral impressed 
submargin punctate, and the margin strongly reflexed 
and a little curved, the anterior angle subacuminately 
produced; the humeral margin long, a little sinuated. 
Scutellum and hemielytra covered with prostrate bronze- 
yellow pubescence. Legs greenish yellow, with the nails 
and incisures of the joints, the spines, and some minute 
specks on the femora and tibia, black; femora and tibiz 
with some obscure stripes; the middle coxe and pectoral 
segments more or less black. Ventral segments broadly 
bordered with black, this color sometimes expands into 
spots on the connexivum, and each side of the middle 
line. 

Length to tip of venter, 8-g mm. Width of pronotum, 
44-434 mm. 

One specimen was found at San José del Cabo by Dr.

CoRISA INSCRIPTA N. sp. 

Elongate, with a short head and long, nearly triangular 
pronotum, the ground color pale dull testaceous marked 
with dark brown very slender short lines in uneven long- 
itudinal series. Head highly polished, moderately con- 
vex, a little triangularly expanded against the pronotum, 
with the occipital submargin linearly impressed, and the 
middle acuminate; middle of vertex of female with a few 
scattered punctures and a feebly elevated longitudinal 
line; face a little hairy, a little depressed in the female, 
with the front of vertex correspondingly convex, fossa of 
the male ovate, with the narrow end below, occupying 
nearly all of the width between the lower end of the eyes 
and most of the face. Pronotum highly polished, with 
the medial carina barely suggested, the surface convex 
and crossed by about fourteen brown slender lines, the 
anterior angle with a yellow bare spot, and behind it the 
submargin is broadly impressed. The pleural pieces 
pale dull yellow, the sternum of the same color, but the 
prosternum and a streak outside of the middle coxe black 
in the male. Palzw of male short, wide depressed, very 
broad-cultrate with the lower margin concave, set with 
very long bristles, and an acute tip; pale of female a lit- 
tle longer, deeply excavated. Clavus wide and long,

been taken in the vicinity of Cape St. Lucas, but they 
were too much damaged to admit of identification. 


DESCRIPTIONS OF THREE NEW LIZARDS FROM 
CALIFORNIA AND LOWER CALIFORNIA, WITH 
A NOTE ON PHRYNOSOMA BLAINVILLII. 


BY JOHN VAN DENBURGH. 


PHRYNOSOMA FRONTALIS Sp. Nov. 

The long-spined horned toad of California has been 
sometimes called Phrynosoma coronatum Blain., some- 
times P. bfainvillic Gray. Dr. Stejneger has recently * 
called attention to the fact that the latter name only can 
be available, the form found at Cape St. Lucas (the type 
locality of P. coronatum) being distinct from that of Up- 
per California. An examination of a very large series 
of horned toads in the museums of the Leland Stanford 
Junior University and the California Academy of Sciences, 
not only confirms Dr. Stejneger’s position, but shows that 
there are in Upper California two distinct species, which 
seem never to have been separated. These are: a south- 
ern form, occupying San Diego County and extending 
into Lower California at least as far as San Tomas, char- 
acterized by the convex and almost smooth scales on the 
head; anda northern one in which the head scales are 
flat and roughened with small granules; both have the 
head scales yellow with minute brown dots. In P. coro- 
natum the head plates are flat and rough, black or very 
dark brown with light edges. 

I have learned from Mr. Boulenger, through the kind- 
ness of Dr. Gilbert of Stanford University, that the type 
of P. dlainvillit has all the characters of the San Diego 
form. P. dlainvilliz Gray is, therefore, not a synonym of 
P. coronatum Blain., and is the name of the species which 
inhabits northern Lower California and San Diego County,

THREE NEW LIZARDS. 297 


California. Ihave therefore selected one of the north- 
ern specimens for my type of P. frontalis. 

Description: Adult male (Type No. 93, Leland Stan- 
ford Junior University Museum, collected by C. H. Gil- 
bert and W. W. Price in Bear Valley, San Benito County, 
California, March 31, 1893). Nostril pierced in the 
line of the canthus rostralis. Head spines, one occipital, 
three large posterior and two smaller anterior temporals, 
and one postorbital, on each side; and one small inter- 
occipital. The enlarged plates below the infra-labials are 
large and pointed, five on each side, the series sometimes 
continued backward by small spines. Below the rictus 
is a large spine, with a smaller and more pointed one 
behind at ihere are’ three or four series of Jjenlarsed, 
pointed, gular scales on each side, the exterior of which 
are continued back upon the gular folds. <A few of the 
scales in front of the occipital spines are convex or 
pointed, and those on the temporal regions have ridges 
running in the general direction of the temporal spines. 
The other head scales are flat, each with numerous 
granulations, which are usually darker than the ground 
color of the head. There are two groups of spines on 
each side of the neck. Two rows of periphero-abdomi- 
na] spines are present, the lower series shorter than the 
upper and composed of smaller spines. The tail is 
bordered with a single row of lateral spines, and has a 
small group of very long spines just behind the leg. The 
scales on the anterior surfaces of the limbs are large, 
pointed and strongly keeled; those on the chest, abdo- 
men and proximal half of the ventral surface of the tail 
are smooth, but those on the terminal portion of the tail 
are keeled. Tympanum naked. Femoral pores sixteen. 

Color above yellowish-white with large brown blotches, 
largest on nape. Chest and belly bright gamboge-yellow, 


298 CALIFORNIA ACADEMY OF SCIENCES. 


mottled with gray and dusky. Gular regions paler yel- 
lowish-white, mixed with dark gray; the larger scales 
with bright yellow tips. 

Length, 142 mm.; head; 21 mm..'; hind) leo, 60 mimes; 
fore leg, 45 mm.; tail, 52 mm. 

Habitat: Santa Clara, Santa Cruz, Monterey and San 
Benito counties, and near Lemoore, Kings County, Cal- 
ifornia. 

There is great individual variation in the color of the 
specimens before me. This is perhaps explained, at 
least in part, by the fact that a live specimen changed its 
colors considerably in the course of a very few minutes. 
This was particularly well marked upon the chest and 
belly, which changed, in about three minutes, from a 
bright yellow with numerous slate colored spots, to a yel- 
low of a slightly lighter hue from which the black spots 
had entirely disappeared. 


UTA MICROSCUTATA Sp. nov. 

Two specimens of Uta from Lower California, while 
manifestly related to U. nigricauda, as shown by the 
presénce of a single frontal, the general style of the dor- 
sal lepidosis, and the coloration, differ so much from that 
species (by the small size of the dorsal scales, the very 
gradual change from the largest dorsal scales to the 
granular laterals, the blue instead of orange gular patch 
in the male) as to make their separation imperative. 

Description: Adult male (Type, No. 1221, Leland 
Stanford Junior University Museum, collected by J. M. 
Stowell, in the San Pedro Martir Mts., Lower California, 
June 20 or 21, 1893). A-single frontal; four large supra- 
oculars; one large and two small projecting scales on the 
anterior border of the ear. The largest dorsal scales are 
along the median line, on each side of which they be- 
come gradually smaller, until a granular form is assumed 


THREE NEW LIZARDS. 299 


at a distance varying from four to seven rows of scales 
from the median line. Thirty-four of the largest dorsal 
scales equal the length of the shielded part of the head. 
A slight dermal fold extends from above the thigh to 
near the upper end of the oval ear-opening. There is a 
strong gular fold, edged with rounded scales which are 
slightly larger than those just in front. The dorsal and 
posterior surfaces of the thighs, and the posterior surfaces 
of the arms, are finely granular. The other portions of 
the limbs are covered with scales, which are smooth on 
the ventral surfaces of the thighs, legs, arms and fore- 
arms, but keeled elsewhere. Scales on ventral parts of 
body smooth. Scales on back of tail much larger than 
those below, both strongly keeled. Femoral pores, four- 
teen on the left side, thirteen on the right. Enlarged 
post-anal plates present. 

Color sooty black, slightly paler below. Back with a 
few irregularly-scattered light spots, and with nine pairs 
of faintly-marked vertebral bars of a deeper black. 
Chest and belly indigo; chin and throat azure; pre- and 
post-anal regions tinged with azure. 

Length of head and body, 45 mm.; of tail, 84 mm.; 
of hind leg, 31 mm.; of fore leg, 21 mm. ; of hind foot, 
13 mm.; of shielded part of head, ro mm.; of head to 
posterior border of ear, 11 mm. Depth of head, 6 mm.; 
its greatest width, 8 mm. 

Adult female (No. 1222, Leland Stanford Junior Uni- 
versity Museum, collected by J. M. Stowell in the San 
Pedro Martir Mts., Lower California, June 20 or 21, 
1893). Differs from male in having thirty-two instead 
of thirty-four dorsal scales equal to the shielded part of 
head, and in having fifteen femoral pores. The general 
color is slaty gray, almost white below. Back with dark 
markings as in male. A gular patch of lemon yellow.

CNEMIDOPHORUS STEJNEGERI Sp. nov. 

Cnemidophori from northern Lower California and 
from San Diego County, California, present much the 
general appearance of C. ¢égrzs undulatus (Hallowell). 
They differ from that form in having the dorsal scales 
smaller, the gular scales and the scales on the collar 
larger, and in the presence of large and well-defined 
black spots on the gular region. From C. ¢zgris B. & G. 
they differ by character of the scales as above indicated, 
by the absence of the slate-colored suffusion on the gular 
regions, and by the well-defined black markings on the 
sides of the head. 

As shown by Dr. Stejneger,* C. t2grzs is the desert 
form found in eastern California as far south as the 
Mojave Desert, in southern Idaho, in Nevada, and in, 
Utah. C. tagr?s undulatus inhabits the western slopes of 
the Sierras, and is also found on the western side of the 
interior valley of California, as is shown by specimens in 
the Museum of the Leland Stanford Junior University 
from Kelseyville, in Lake County, and from Los Gatos, 
Santa Clara County. 

I take pleasure in dedicating this new form to Dr. 
Leonard Stejneger, who has recently made such impor- 
tant additions to our knowledge of Californian herpet- 
ology. 

Description: Adult male (Type, No. 1061, Leland 
Stanford Junior University Museum, collected by J. M. 
Stowell between San Rafael and Ensenada, Lower Cali- 
fornia, June 8, 1893). Nostril anterior to nasal suture; 
three parietals; two fronto-parietals; four supra-oculars; 
six superciliaries; nasal not reaching second superior 
labial; post-nasal in contact with both first and second 


“North American Fauna. No. 7, p. 201, 1893. 


THREE NEW LIZARDS. 301 


superior labials. Posterior gular scales rather large, ab- 
ruptly separated from the very large and convex anterior 
gulars. Plates of collar very large, but smaller along its 
edge. Ventral plates in eight longitudinal rows. Back, 
neck and upper surfaces of limbs covered with very 
small, smooth, convex granules. Five rows of brachial 
plates; three rows of antebrachials; no post-antebrachial 
plates. Femoral plates in seven rows. Twenty and 
twenty-two femoral pores. Scales on tail large, oblique, 
slightly pointed, and with strong diagonal keels. 

Color, above yellowish-brown posteriorly, becoming 
grayish towards head, paler on sides; with nine longitu- 
dinal rows of very irregular black spots. Upper surface 
of limbs similarly marked. Black markings on sides of 
head and neck and on gular region large and well defined. 
Lower surfaces creamy white, maculated with black. 

Length, 343.mm.; head, 26 mm.; hind leg, 70 mm.; 
fORe ering y mum. 3 tail 252: 

Habitat: Northwestern Lower California, and San 
Diego County, California. 

Twelve other specimens collected by Mr. Stowell at 
the type locality, at San Telmo, and in the foothills of 
the San Pedro Martir Mountains, Lower California, do 
not differ from the type in any important particular. The 
number of femoral pores varies from nineteen to twenty- 
five, of brachial plates from four to five rows and of ante- 
brachials from two to three rows. 

Forty-one specimens from San Diego County, Califor- 
nia (collected in Santa Ysabel, Clogston’s and Hemet 
Valleys; at San Jacinto and in the Julian Mountains, by 
Messrs. Hyatt and Stoddard), are essentially like those 
from Lower California, but average slightly paler in gen- 
eral coloration. 


THE COLEOPTERA OF BAJA CALIFORNIA. 
BY GEORGE H. HORN. 


Our earliest knowledge of the Coleoptera of the Penin- 
sula of California was obtained from a collection made 
by John Xantus de Vesey during 1859 and 1860, which, 
after its deposit in the Smithsonian Institution, was divided 
between Mr. H. Ulke and Dr. J. L.. LeConte. The 
series was said to contain about 500 species, of which 
Dr. LeConte admits having seen 114. It is highly prob- 
able that Xantus greatly overestimated the species col- 
lected as the accompanying list is less than 700, many of 
which are new. 

A few years later a small collection was made by the 
late W. M. Gabb, who, with some associates of the Geo- 
logical Survey of California, visited parts of the penin- 
sula. Unfortunately the localities from which this col- 
lection was obtained were not specified, although many 
are now ascertained through the collection under con- 
sideration. 

No definite localities are known for the Xantus collec- 
tions and all the species heretofore described are stated to 
be from Cape St. Lucas. It is now determinable that 
this material was obtained in the region between San José 
del Cabo and La Paz. 

The collection submitted to me by the California Acad- 
emy of Sciences is by far the largest aggregate of material 
from Baja California submitted for scientific study and 
includes within five per cent. all the species known to 
have occurred in that region, together with a good num- 
ber of new forms and some hitherto known only from the 
adjacent mainland of Mexico. To the expeditions from 
the Academy in the last five years we are indebted for 
this increase of our knowledge of the coleopterous fauna 


2D SER., Vou. IV. August 3, 1894. 


COLEOPTERA OF BAJA CALIFORNIA. 303 


of the region, the most important series being that col- 
lected in 1893 in the region around San José del Cabo 
by Dr. Gustav Eisen. 

The present study enabled me to confirm the views ex- 
pressed by Messrs. Baird, Cope and LeConte, and, at 
the same time, to correlate details of distribution so that 
we come more nearly in accord with the botanical indica- 
tions. 

It seems to me unnecessary to repeat the geographical 
details of the peninsula, as they have been so clearly 
demonstrated by Mr. Brandegee in vol. ii of these Pro- 
ceedings. In order that remarks to be made in this paper 
may be understood without reference to those of Mr. 
Brandegee, it may be stated that the peninsula is a nar- 
row strip of land about 700 miles long, running in a south- 
southeasterly direction from the southern boundary of 
California, varying greatly in width, although in a general 
way narrowing from north to south. Through the axis 
runs a chain of mountains of a general elevation of 3,000 
to 4,000 feet, The western slope is bordered by the 
Pacific Ocean, the eastern by the Gulf of California. 

I have had occasion to note in speaking of the fauna 
of Guadalupe Island that the cold arctic current, which 
skirts the western shore of the North American conti- 
nent, tends to render the insect fauna of the coast region — 
very nearly uniform as far south as Point Conception, 
where the bluff coast and the rather abrupt eastern trend 
of the coast line deflect the current, or rather the coast 
recedes from the current, the climate becomes warmer 
and many interior species reach the coast. The western 
coast of the peninsula continues the general trend of the 
coast line from Santa Barbara, so that no portion of it 
seems to come within the influence of the Arctic current. 
On the eastern or gulf coast, the mountains and foothills 


304 CALIFORNIA ACADEMY OF SCIENCES. 


approach the water and the entire region is comparatively 
barren with but few springs or water holes and is not un- 
like many parts of Arizona. 

The most interesting and characteristic part of the 
peninsula is that called appropriately the Cape Region 
and which Mr. Brandegee defines as follows: ‘*‘ By the 
‘Cape Region’ is meant that part of the peninsula south 
[east] of a line drawn along the northern [western] base 
of the mountains from Todos Santos to La Paz.’ The 
brackets in the above quotation are my own, as the maps 
show that the line from Todos Santos to La Paz is a 
north and south line. 

As might be inferred, the coleopterous fauna of the 
San Diego region extends southward along the ocean 
side of the peninsula, with no striking admixture of spe- 
cies new or foreign to it. There are, however, long 
reaches of the coast region not yet visited. 

From the northern end of the peninsula, nearly mid- 
way between the gulf and sea coasts and about roo miles 
south of the political boundary line of California, an in- 
teresting series of 65 species has been sent me from the 
region of the San Pedro Martir Mountains, showing a 
very decided relationship with the fauna of the regions of 
Los Angeles and Santa Barbara. 

The fauna of the gulf coast region indicates a decided 
relationship with and in fact is a continuation of the fauna 
of Arizona and the Colorado Desert, quite a number of 
the species extending to the lower Rio Grande of Texas, 
and a few species have been recognized as identical with 
those of the northern states of Mexico. 

The Cape Region is by far the most interesting and 
peculiar, from the fact that we have the greatest number 
of new forms with a decidedly tropical aspect and rela- 
tionship. This region could be excluded from the Boreal 


COLEOPTERA OF BAJA CALIFORNIA. 305 


American fauna and be considered as belonging to that 
of Central America. 

Although politically a portion of the Republic of Mex- 
ico, the editors of Biologia Centrali-Americana have not 
considered the region as properly within their province by 
reason of the strong claims made for it as a part of the 
faunal region of our southwest. 

The following pages consist of two distinct parts—a 
catalogue of all the species known to me as having been 
collected in Baja California, followed by descriptions of 
new species or comments on new occurrences. 

The catalogue is a systematic one, following the order 
of the families of our most recent lists. Following each 
species is a list of localities, giving the general distribu- 
tion as far as known to me, and in each case the special 
localities as given by the collectors. A certain number 
of species are from unknown localities; those of the 
Xantus series are quoted as from ‘‘Cabo San Lucas.”’ 
In the case of a few in Mr. Ulke’s cabinet, and not else- 
where represented, they are quoted ‘‘ Baja California 
(Ulke).’’ The greater part of the latter are doubtless 
from the Cape Region, but species are among them col- 
lected south of San Diego. 

The descriptive part contains descriptions of new spe- 
cies. The names appear in their proper places in the 
list, but the descriptions have been separated, so that the 
catalogue will not be broken up irregularly. 

By the kind permission of the Publication Committee 
of the Academy, I have added descriptions of a number 
of new species either from adjacent regions or by reason 
of their relationship to those included by right in the 
paper. 

I must at this time acknowledge the assistance render- 


ed by Mr. H. Ulke of Washington, in completing the

VESPEROCTENUS FLouHRI Bates. Plate 8, figs. 1, 2, 3. 
For the identification of this insect I am indebted to Mr. 
Julius Flohr, whose timely visit alone saved me from a 
synonym as I never would have suspected that Mr. H. 
W. Bates, with whom the Cerambycide were a special 
study, would have placed this insect in that family. 

The facies of this insect, less the antenna, is somewhat 
that of a Toxotus and to my eye that of Callirhipis, al- 
though the elytra are more narrowed behind, due to some 
extent to the shrinking from drying. 

As remarked by Lacordaire in his characteristics of 
the family, the anterior and middle coxe are conico-

cylindrical, the former contiguous and with distinct tro- 
chantin. The last joint of the tarsus with a_ setose 
onychium, not at all prominent however in the present 
genus. ‘The tarsi are not lobed beneath, the third joint 
acutely notched, the fourth small and not visible beyond 
the emargination of the third. The first and fifth joints 
are equal, the second and third nearly so, but shorter 
than the other two. 

The head is transversely oval, slightly prolonged behind 
the eyes and abruptly forming a neck. The eyes large, 
rounded, slightly truncate in front, rather coarsely granu- 
lated. Antennal tubercles spiniform. Antenne twelve- 
jointed and flabellate (in the males) joints 3 to 11 with a 
slender branch which is slightly longer than the length 
of the preceding part of the antenne, that is to say the 
branch from the third joint is longer than joints 1 to 3 of 
the antenne and so continuously. The terminal joint 
and the branch from the preceding are equal in length. 
The mandibles are falciform, prominent and strongly bi- 
dentate at middle. The maxillary palpi are long, slender 
and four-jointed, the second joint longest, third joint 
two-thirds as long, fourth a little shorter than second and 
slightly fusiform. Labial palpi slender and long, the 
last two joints about equal in length. The mouth-parts 
otherwise are feebly developed. Thorax conical with 
slightly arcuate sides, the lateral border not very distinct. 
Elytia broader at base than the thorax, sides convergent 
to apices, these separately rounded, substance coriaceous. 

The comments above apply to the male; the other sex 
is unknown to me, but Mr. Bates describes the antennz 
as half the length of the body, filiform and_ simple. 
While I greatly regret to differ so radically from my la- 
mented friend H. W. Bates in the systematic position of 
this insect, the aggregate of its organization points to the 


326 CALIFORNIA ACADEMY OF SCIENCES. 


family in which it is here placed. The fact that the 
tarsi are five-jointed removes it from association with 
any but the most aberrant Cerambycide in the earlier 
groups of Prionides, with which no one would pretend to 
associate this insect. That the fourth tarsal joint is 
small might seem an objection to its association with the 
Rhipiceride, but this is by no means insuperable, as in 
an adjacent family, Dascyllide, we have an entire group, 
the Ptilodactylini, so constituted. In view of the fact 
that the family Rhipicerida contains but few genera not 
requiring tribal subdivision for their elucidation, I would 
suggest that Vesperoctenus be placed near Callirhipis, 
from which it differs in its twelve-jointed antenna and 
the small fourth tarsal joint. 

Occurs at San Francisquito in the Cape Region and in 
Mexico.

This species varies in color. It may be entirely black, 
or with the head and thorax dark and elytra testaceous, 
the latter often darker along the suture and sides. 

It seems to have escaped observation that the sexes are 
very readily separable. The males have no anterior tibial 
spur and the pygidium as long as wide and regularly 
convex. The female has an anterior tibial spur, the 
pygidium broader than long and slightly concave near

have received new names. I have already called atten- 


tion to the fact that the same species developing at differ- 
2D SER., VoL. IV. ( 23 ) August 3, 1894,

ent seasons will have a very different aspect. Those 
developing in the hot and dry season will be shining, and 
if pubescent or hairy, will remain so but a short time, 
while the specimens of the colder or wet seasons will be 
opaque and retain their pubescence or hair a longer 
time. Some localities, owing to their climate, will retain 
one of these variations, as shown in /Ahkthimus serratus, 
in the damp and cooler climate of the coast and mountain 
regions of Oregon and Washington. ‘This species be- 
comes gradually smoother as it goes south, until near 
San Bernardino and the hot regions bordering the Mojave 
Desert it is quite smooth. Unfortunately, some of the 
varieties of this have won new names undeservedly. One 
of the specimens of Edrotes before me has the surface 
dull and coated with a dirty white efflorescence. In 
species of other genera observed in nature by myself this 
seems dependent on seasonal influences also. 

E-drotes ventricosus occurs probably along the entire 
eastern side of the peninsula, but specimens have been 
sent trom San José del Cabo only.

DESCRIPTIONS OF NEW SPECIES. 


The following pages contain the descriptions of all 
those species believed to be new to science contained in 
the series sent me for examination. At the same time I 
have described a number of new species from regions 
in which the fauna is more or less related to that under 
consideration. In every instance in which a species is 
described from the series in the collection of the Acad- 
emy the type is the specimen or specimens making 
part of that collection. 


ANCHONODERUS APICALIS n. Sp- 


Form of guadrinotatus but more depressed, piceous, 
legs pale, elytra fusco-testaceous the apex irregularly 
piceous. Antenne piceous, the basal joint pale. Mouth 
parts pale. Elead piceous smooth. Uhorax cordate 
broader than long, disc slightly convex, a finely impress- 
ed median line, surface alutaceous, very sparsely finely 
punctate. Elytra finely striate, intervals flat, finely not 
closely punctate. Prothorax beneath and metapleure 
smooth, abdomen sparsely punctate. Epipleure and 
less pale Lenoth 23 ineh 7 mm 

The entire surface is sparsely clothed with a very fine 
and short, erect pubescence. While the general form is 
that of guadrinotatus the form is more depressed and the 
thorax broader. The color of the elytra is not due to 
immaturity, as two specimens collected at different times 
agree. 

El Taste and Sierra Laguna. 

APRISTUS SUBCYANEUS 0. sp. 

Similar in form to /atzcollis, deep cobalt blue, moder- 
ately shining, antenne and legs black. Head smooth. 


Thorax wider than long, narrowed at base, lateral mar- 
gin extremely narrow, median impression nearly entire, 


COLEOPTERA OF BAJA CALIFORNIA. 361 


surface smooth. Elytra very indistinctly six-striate, striz 
not punctured, the sutural alone entire. Body beneath 
black, smooth. Length, .11 inch; 3 mm. 

This species more nearly resembles a Blechrus by its 
slender less depressed form and by the very narrow tho- 
racic margin, but it cannot be associated with that genus 
as the base of the thorax is truncate. It differs from all 
the known species of Apristus by its decidedly blue color 
and the very feebly impressed striz. 

San José del Cabo. 


CALLIDA RUGICOLLIS n. sp. 


Oblong, depressed, piceous black, feebly shining, a 
slight greenish surface lustre more evident on the head 
and thorax. Antenne black, first joint testaceous be- 
neath. Head nearly smooth. Thorax wider than long, 
slightly wider at base than at apex, sides moderately ar- 
cuate, feebly sinuate posteriorly, disc convex, slightly de- 
pressed along the sides, margin reflexed, median im- 
pressed line entire, surface with transverse and slightly 
undulating ruge. |Elytra finely striate, strie entire, 
finely and closely punctate, intervals flat, very evidently 
punctate, less distinctly toward the apex, third interval 
with four dorsal punctures. Body beneath smooth and 
shining, with evident zneous lustre, a few punctures at 
sides of metasternum. Length, .40o-.44 inch; 10-11 mm. 

This species belongs to the group in which the males 
have two or three and the females two anal sete. It 
seems to be allied to obscura Dej. by the punctate elytral 
intervals and the transversely wrinkled thorax. C. plan- 
ulata Lec. is also probably related, but that species is 
not now in hand for comparison.

2p SER., VOL. IV. ( 24) August 3, 1894, 


362 CALIFORNIA ACADEMY OF SCIENCES. 


THERMONECTES PENINSULARIS n. sp. Plate viii, fig. 10. 


Oval, moderately convex, shining, yellowish testaceous, 
elytra closely irrorate with small black spots. Head 
pale, a small vertical transverse piceous spot, occiput nar- 
rowly piceous. ‘Thorax almost entirely yellow, the usual 
apical and antebasal black lines closely approximated and 
very near the base. Elytra closely irrorate with black 
spots, the border pale except near the apex, without trace 
of transverse fascia except a larger black spot one-third 
from apex, surface of elytra smooth, the rows of coarse 
punctures nearly obliterated. Body beneath rufescent, 
prosternum, front and middle legs pale. Length, .41 
inchs. 10.5 tm. 

The single specimen seen isa male. In general ap- 
pearance it resembles ornatzco//is, but is smaller and 
broader. It differs from all the species known to me 
belonging to the same group, by the absence of the ely- 
tral fascia and the peculiar style of thoracic ornamenta- 
tion. 

San José del Cabo. 


STAPHYLINUS LUCANUS DN. sp. 


Slender, dull black, opaque, last dorsal in part, last 
ventral entirely castaneous. Antenne not long, joints 
5-10 transverse, black, the under side of the first joint 
at apex and the basal half of the second reddish. Head 
subtriangular, densely punctured, a smooth median line 
posteriorly, surface with very short erect black pubes- 
cence. Eyes not as long as half the sides of head: 
Thorax a little wider than long, truncate in front, sides 
parallel, base rounded, surface densely punctate with a 
narrow smooth median line, surface pubescent similarly 
to the head. Scutellum velvety black. Elytra more 
finely and densely punctured than the head and thorax 


COLEOPTERA OF BAJA CALIFORNIA. 263 


but similarly pubescent, fimbriate at apex. Abdomen 
above sub-opaque, finely but not densely punctate, each 
segment with a double series of oblong velvety spots; 
beneath more shining and more sparsely punctate. Legs 
black. Length, .55 inch.; 14 mm. 

The male has the last ventral truncate and vaguely 
emarginate. This species belongs to the division Platy- 
dracus Thoms., which Dr. Sharp does not admit as of 
full generic value. In form the above described species 
resembles xzgrel/us, but differs in the form of the head 
and the presence of velvety spots on the abdomen. From 
the arrangement of our native species suggested by me 
(Trans. Am. Ent. Soc. vii, p. 186) /ucanus will be found 
most closely related to fomentosus, but the latter is more 
robust and has no smooth median thoracic line. 

Occurs at La Chuparosa. 


SCAPHISOMA PENINSULARE D0. sp. 


Form of ¢erminatum but smaller, piceous black shin- 
ing, elytra narrowly paler at apex, legs and two basal 
joints of antennz pale. Head and thorax smooth. Elytra 
relatively coarsely, sparsely punctate, the punctures less 
distinct at base, sutural striae curved outward at base, 
one-third toward humeri. Body beneath smooth. Length, 
.04 inch; I mm. 

This species is evidently related to desertorum Casey, 
but is smaller and with more coarsely punctured elytra 
and a shorter basal extension of the sutural stria. 

Sierra Laguna. 


SCAPHISOMA APICALE ND. sp. 


Form of convexum. Body beneath rufo-testaceous, 
legs paler, head and thorax slightly darker, elytra piceous 
broadly tipped with rufo-testaceous. Head smooth, 
thorax microscopically punctulate. Antenne pale, the 


364 CALIFORNIA ACADEMY OF SCIENCES. 


outer joints darker. Elytra finely and moderately closely 
punctate. Metasternum and first ventral segment sparsely 
finely punctulate.. Length, .10 inch; 2.5 mm. 

This form is related to punctulatum, but differs from all 
our species by its coloration. In the specimens examined 
there is uniformity except that the thorax may be some- 
what darker than at the sides. 

La Chuparosa. 


SAPRINUS OPACUS DN. sp. 


Broadly oval, convex, black, opaque, punctured. 
Head densely punctate, front not margined. Thorax 
densely punctate, very slightly strigose at the sides. Elytra 
opaque, punctures smaller than those of the thorax and 
less closely placed, especially in the circum-scutellar re- 
gion; sutural striae extremely fine, obliterated at basal 
third, dorsal striz four, the outer side of each raised in 
a fine carina, the first longer, arcuate and nearly entire, 
second and third shorter, fourth much shorter and with 
a distinct arch at base; internal subhumeral short, oblique, 
the outer long and fused with the marginal. Pygidium 
closely punctate like the thorax. Prosternum nearly flat, 
the striz sinuous, but gradually convergent in front with- 
out quite uniting. Metasternum at sides coarsely punc- 
tate, at middle and the abdomen sparsely finely punctate. 
Anterior tibiz 7-denticulate. Length, .14 inch; 3.5 mm. 

This peculiar species will be referred to Group ii, as 
defined by Leconte, but is one of those exhibiting the 
difficulty attending the Marseul system of subdivision. 
From all the species known in our fauna with immarginate 
front this one may at once be known by its opaque and 
punctate surface, the nearly flat prosternum with con- 
vergent striz. 

One specimen. San José del Cabo. 


COLEOPTERA OF BAJA CALIFORNIA. 365 


TERETRIUS LEVATUS DN. sp. 


Cylindrical, piceous black, shining, legs brown. Head 
finely not closely punctate. Thorax sparsely punctate, 
fine at apex and sides, coarser near the base. Elytra 
more coarsely punctate, the punctures finer near sides 
on apex, a smooth umbonal space, a short very oblique 
stria at base. Pygidium sparsely punctate. Mesoster- 
num distinctly margined in front, sparsely coarsely punc- 
tate. Anterior tibia 4-denticulate, middle tibia 4-spinose, 
hind tibiz bispinose near apex, with a smaller spine at 
middle. Weneth, .1o mech; 2.5 mm: 

A species resembling ob/¢gualus in most of its characters, 
but much smaller and with one less spine on the middle 
and hind tibiz, the spines being at the same time more 
slender. 

San José del Cabo. 


ANORUS PARVICOLLIS n. sp. 


Elongate, parallel, yellowish testaceous, head rufes- 
cent, under body slightly piceous, surface shining. Head 
sparsely punctate, with long, sparse hairs. Thorax 
smaller in bulk than the head, but, excepting the eyes, 
slightly wider, twice as wide as long, not broader at base, 
sides obtusely angulate at middle, lateral edge rounded, 
surface sparsely punctate with long sparse hairs. Elytra 
broader than the thorax, but scarcely wider than the head 
across the eyes, surface vaguely striate, slightly wrinkled 
near the apex, intervals with sparsely placed short erect 
hairs. Body beneath more or less piceous, very sparsely 
pubescent, the segments 3-4-5 of abdomen more closely 
pubescent in their distal half. Legs sparsely pubescent 
with longer flying hairs. Length, .32 inch; 8 mm. 

This insect has not yet occurred in Lower California, 
but from the fact that it was collected at Fort Yuma may 


366 CALIFORNIA ACADEMY OF SCIENCES. 


be expected. Differs from A. pzcews in the form of the 
thorax and the scarcely pubescent surface. 
Occurs in Arizona near Fort Yuma. 


LACON ILLIMIS nN. sp. 


Brown or ferruginous, subopaque, sparsely clothed with 
yellowish, scale-like hairs, antennz and legs paler. Head 
coarsely and closely punctate. Thorax a little longer than 
wide, sides arcuate in front, from middle to base nearly 
straight, margin crenulate, hind angles slightly prom- 
inent externally, without carina, disc coarsely, closely 
punctate, a depression in front of the scutellum. Elytra 
not distinctly striate, the intervals faintly indicated, punc- 
tures coarse, closely placed and in feebly indicated rows 
with closely placed and but little finer punctures in the 
intervals. Body beneath with coarsely, closely and equal- 
ly disposed punctures. Propleurz without groove for the 
tarsus. Length, .28-.32 inch; 7-8 mm. 

By all its structural characters this species should take 
its place near Lezelewczt as given by Candeze, but differs 
from that by its smaller size and the elytral sculpture. 
The elytral punctures are so closely placed that it is diff- 
cult to distinguish those of the striae. 

Occurs at Tucson (Wickham) and near Yuma, Ariz. 


CHRYSOBOTHRIS BICOLOR Nn. Sp. 


Form of ¢exvana, but without trace of coste or fovee 
on the elytra, head and thorax bronze black, elytra green 
feebly shining. Clypeal emargination broadly oval. Head 
closely punctate, vertex more finely, sparsely pubescent. 
Thorax rather more than twice as wide as long, sides 
slightly divergent posteriorly, hind angles slightly co- 
arctate, anterior angles obliquely truncate, disc regularly 
convex without depressions, coarsely punctured, less 
closely at middle, densely at the sides. LElytra slightly 


COLEOPTERA OF BAJA CALIFORNIA. 367 


wider at base than the thorax, humeri rounded, sides 
parallel, arcuately narrowing at apical third with the 
margin rather coarsely serrate, apex obtuse, disc con- 
vex without costa or fovee except the usual basal de- 
pression, the surface not closely submuricately punctured, 
the intervals alutaceous. Body beneath coarsely and 
closely punctate with few hairs, the abdomen smoother 
and with more cupreous luster at the sides. Last ventral 
with an entire lateral margin and a well defined supple- 
mentary margin serrate near the apex. Length, .27 inch: 
7 mm. 

Male.—Anterior femur with a broad triangular tooth 
serrate on its distal edge, the tibia slightly arcuate. Last 
ventral with an acute angle each side, the interval be- 
tween them bisinuate. 

This species belongs with those in which the last ven- 
tral segment has an entire edge without serrulation and 
where the elytra have neither discal fovea nor costa. In 
a general way it resembles ana/rs. 

One specimen. San José del Cabo. 


CHRYSOBOTHRIS LUCANA DN. Sp- 


Form resembling chrysoe/a and but little larger, metal- 
lic green or with the elytra blue, moderately shining, 
elytra with an opaque black band not reaching the suture 
or side, broadest internally, a similar band in front ot 
apex, behind the base an oval spot, united to the median 
band by a slight isthmus. Head rather coarsely and 
closely punctate, a vague transverse ridge in the female; 
clypeus semicircular each side, an acute incisure at mid- 
dle. Thorax one-half wider than long, sides somewhat 
sinuous, anterior angles oblique, surface moderately 
coarsely, but not closely punctate. Elytra with nearly 
parallel sides, arcuately narrowing at the apical third

Sierra E] Chinche (2,000 feet) and San Jose del Cabo. 

This species belongs to a small group represented by 
four forms peculiar to the fauna of western Boreal- 
America and three to Mexico, one of the latter occurring 
in Arizona. The essential characters of the group are: 
last ventral segment not serrulate at the sides, elytra 
separately rounded at apex without trace of cost or 
discal fovee. With the exception of praszna the elytra 
in all have three purple-black fasciz more or less broken 
according to the species. 

The forms known may be arranged in the following 
manner: 


Species rather large and of robust form, tip of abdomen exposed, punc- 
tuation of surface rather coarse; elytra with three interrupted black 


fascia. 
Sides of thorax regularly arcuate. atrifasciata. 
Sides of thorax oblique in front. Ulkei. 


Smaller and more depressed species, elytra entirely covering the abdomen, 
punctuation not dense. 
Elytra with the usual purple-black fascie. 
Anterior angles of thorax obliquely truncate. 
Sides of thorax nearly straight; elytral bands reaching the suture. 
juneta. 
Sides of thorax sinuous; elytral bands not united across the suture. 
lucana. 


COLEOPTERA OF BAJA CALIFORNIA. 369 


Anterior angles not obliquely truncate; sides slightly arcuate; elytral 
bands interrupted. 


Surface somewhat dull. socialis. 
Surface shining. trisignata. 


Elytra without darker fascia. 
Body bright green; anterior angles of thorax not obliquely trancate. 
; prasina. 
Body bicolored above; anterior angles of thorax obliquely truncate.

From specimens examined by me socéal7s and tris/g-nata 
seem not to be distinct specifically. 


ACMODERA SCAPULARIS n. sp. Plate viii, fig. 6. 


Similar in form to favomarginata, but rather more at- 
tenuate posteriorly, piceous black with faint bronze 
tinge. Head coarsely closely punctate, front sparsely 
hairy and longitudinally impressed. Thorax more than 
twice as wide as long, wider slightly behind the mid- 
dle, sides obliquely arcuate in front, behind the middle 
slightly sinuate, the hind angles rectangular, lateral 
margin acute and slightly reflexed, concealed near the 
hind angles, disc with a moderately deep triangular de- 
pression at middle and a deep oblique impression each 
side, surface coarsely and moderately closely punctate, 
very sparsely hairy, a yellow spot near the angulation. 
Elytra as wide as the thorax at base, gradually narrowed 
with but slight arcuation to apex, the margin from middle 
to apex serrate, disc slightly depressed, fifth interval finely 
costiform nearly to apex, punctures coarse and close, 
larger and closer exterior to the costa, the intervals smooth 
with a single row of punctures each bearing a short hair, 
the intervals near apex exterior to the costa muricate, sur- 
face muculate with yellow—beginning behind the humeri 
the marginal interval is yellow nearly to apex with an in- 
terruption opposite the last ventral suture, near the mid- 
dle on each side the marginal line expands in an oblique 


370 CALIFORNIA ACADEMY OF SCIENCES. 


plaga of irregular form, sending a small branch nearly 
to the suture, a yellow spot each side of the scutellum, a 
smaller one posteriorly, one fourth from apex an irregular 
arcuate band behind which is a small round spot. Body 
beneath brown bronze, shining, moderately coarsely not 
closely punctate, the propleural punctures coarser. An- 
terior margin of prosternum trisinuate and forming each 
side an obtuse short spine. Surface beneath and legs 
sparsely clothed with moderately long whitish hairs. Last 
ventral with single margin. Length, .52 inch; 13 mm. 

The markings of this species resemble those of /lavos- 
ticta Horn (nec flavosticta || Waterh.) From the char- 
acters given this species must be placed in the group 
Acmaeodere sinuate (Trans. Am. Ent. Soc. vii, 1878, 
p- 4), and, while related to favomarginata by most of its 
characters, it seems best placed after cufrzna which is 
the only species in our fauna with the sub-costiform eleva- 
tion, although the character is faintly indicated, also, in 
flavomarginata., 


Sierra E] Chinche. 
ACMAZODERA STIGMATA n. sp. Plate vii, fig. 2. 


Subcylindrical, nearly of the form of Postma luctuosa, 
dull blue, subopaque, sparsely pubescent, each elytron 
with a round red spot at the margin one-third from apex. 
Front feebly convex, not coarsely nor closely punctate, 
sparsely hairy. Thorax about a half wider than long, 
sides regularly arcuate from base to apex, side margin 
narrow and not visible from above, disc convex, a very 
vague depression at middle of base and a more distinct 
fovea each side, surface moderately coarsely and closely 
punctate and sparsely hairy. Elytra nearly parallel, sides 
narrowed at apical fourth and distinctly serrate, disc con- 
vex, the striza impressed at sides and apex, the punctures 
moderately coarse and deep, more so at the sides, inter- 


COLEOPTERA OF BAJA CALIFORNIA. 371 


vals uniseriately punctulate flat at middle, convex at sides 
and apex. Body beneath piceous black, slightly bronzed, 
punctuation rather coarse in the thoracic regions. Ab- 
domen rather finely and closely punctate, less closely on 
the first two segments, at sides with moderately long, 
sparse, whitish hair. Prosternum in front trisinuate, a 
mammiliform elevation each side limiting the points of 
sinuation. Last ventral with a slight ridge within the 
apical margin. Length, .31 inch; 8 mm. 

This species belongs to the group in which the anterior 
edge of the prothorax beneath is trisinuate and with a 
distinct tubercle each side. It must be associated with 
those species in which the thorax is not wider than the 
elytra, having the lateral margin inferior and without yel- 
low spot at the side. 

It may be known from any species in the group, and, 
in fact, from any in our fauna, by the cylindrical and 
convex form and the red marginal spot one-third from 
the apex. 

San José del Cabo. A specimen from Tucson, Ariz. 
(Wickham, 231), has a small red spot between the hu- 
merus and the larger spot. 


ACMAODERA BIVULNERA DN. sp. 

Closely resembling s/7gmata or cu/ta in form, color dark 
blue beneath, elytra bluish or slightly greenish with a 
moderately large red spot, one-third from apex, head and 
thorax piceous slightly bronzed, surface moderately shin- 
ing. Front convex, moderately closely punctate, sparsely 
pubescent. Thorax about one-half wider than long, 
sides gradually, arcuately narrowed to the apex, disc 
convex without depressions, a slight fovea at base on 
each side, surface rather sparsely and finely punctate at 
middle, gradually more coarsely and closely at the side, 
pubescence short and sparse. Elytra slightly wider

at the umbones than the thorax, sides nearly parallel, 
narrowing at apical third, surface with striz of punctures 
not densely placed, the punctures coarser toward apex 
and at the sides where the striz are impressed and the 
intervals convex, a single row of finer punctures in the 
intervals, pubescence scarcely evident. Prosternum tri- 
sinuate in front, forming a short broad lobe at middle, 
which is broadly emarginate with angles rounded, surface 
at middle coarsely and closely punctate, the flanks with 
shallow variolate punctures. Meso-metasternum coarsely 
punctured at middle, with dense silken white hair at the 
sides. Abdomen smooth and sparsely punctate at mid- 
dle, densely punctate at sides, with white silken hair. 
Length, .25-.30 inch; 6.25-7.50 mm. 

This species resembles s//g7ata very closely, and might 
readily be mistaken for it without an examination of the 
prosternum: The present species is, “however, more 
shining, the thorax more finely punctate and the pubes- 
cence at the sides of the body more dense. One speci- 
men has a small red spot immediately in front of the larger 
spot. 

Occurs near Tucson, Ariz. 


ACM#ODERA MACULIFERA n. sp. Plate viii, fig. 5. 


Form of amplicollis, but more flattened above; head, 
thorax and body beneath aeneous, sides of thorax and 
elytra yellow, the latter with three rows of round black 
spots. Front slightly concave, closely moderately evenly 
punctate, hairy. Thorax more than twice as wide as 
long, widest at base, sides narrowing to front, slightly 
arcuate, hind angles (seen from above) obtuse, lateral 
margin visible from above, disc with an impressed line 
behind the apical margin at the sides and parallel with it, 
a broad but shallow sub-triangular depression at middle, 
an oblique impression each side, a broad yellow space

each side not reaching the apex or base, surface coarsely 
and rather closely punctate, becoming cribrate at the 
sides, sparsely hairy. Elytra narrower at base than the 
thorax, sides gradually arcuately narrowing to apex, mar- 
gin serrate, disc with rows of coarse and deep closely 
placed punctures nearly as wide as the intervals, these 
latter uniseriately punctate, each puncture with a black 
hair; color yellow, marked with round black spots ar- 
ranged in three rows, a sutural row of about seven spots, 
the largest scutellar, a median row beginning at the 
umbone, slightly sinuous, of six spots, a marginal row of 
five spots, the anterior one slightly separated from the 
margin. Anterior margin of prosternum trisinuate, at 
middle coarsely and closely punctate, flanks with shal- 
lower variolate punctures. Metasternum more coarsely 
and closely punctate, densely at the sides. Abdomen 
coarsely not closely punctate, punctures equally placed. 
Body beneath sparsely hairy, last ventral segment with a 
double margin at apex, the additional edge forming a 
plate projecting beyond the true edge. Length, .47 inch; 
12 mm. 

The specimen before me is a male from Texas, given 
me by Mr. Ulke. 

In addition to the characters given above, it will be 
observed that along the basal edge of the elytra the sur- 
face is more closely punctate. Among our species, 
maculifera should be placed near amplicollzs, with which 
itagrees closely in formand structural characters, although 
a little flatter. The species is unique, as far as known 
to me, in the style of elytral ornamentation. 

Mr. Waterhouse figures a form which he considers a 
variety of delectabilis Waterh., resembling gwétzfera, 
above described, so closely that they are probably the 
same, but it is not quite so clear that either is merely a

ACMAODERA CLAUSA fi. sp» | Plate vai, fig. 3. 

Similar in general form to ornata, but with narrower 
thorax and slightly more convex, color piceous slightly 
coppery bronze, elytra less distinctly so, elytra and sides 
of thorax ornate with yellow. Front feebly convex, closely 
punctate, a small smooth space at middle, sparsely hairy. 


Thorax fully twice as wide as long, widest at base, sides

regularly arcuately narrowed from base to apex, lateral 
margin not visible from above except near the base, disc 
rather flat, a vague triangular depression at middle, at 
sides flattened, a fovea each side near the base and a 
post-apical impressed line extending from angle to angle, 
surface coarsely and very closely punctate at sides, be- 
coming finer and sparser at middle, yellow border at 
sides not reaching the front angles. Elytra gradually 
narrowed from base to apex, sides serrulate, disc slightly 
convex, striz slightly impressed at sides and apex, punc- 
tures of striz rather fine, becoming much coarser from 
the fitth outward and near the apex, intervals uniseriately 
punctate and near the apex submuricate; an oblique yel- 
low spot in the scutellar region, outer interval yellow to a 
varying extent, a very irregular band at middle, an oblique 
band one-third from apex, not reaching the suture, a sub- 
apical oblique band. Prosternum in front vaguely tri- 
sinuate, at middle sparsely at sides variolately punctate. 
-Metasternum nearly smooth at middle, closely punctate 
and hairy at the sides. Abdomen moderately coarsely 
punctate, smoother at middle, sparsely pubescent. Last 
ventral with a distinct double margin at apex. Length, 
.37-.40 inch; 9.5-IO mm. 

This species belongs to the series of the ‘‘ sinuate,”’ 


COLEOPTERA OF BAJA CALIFORNIA. 275 


with the thorax not wider than the elytra and margined 
at the sides with yellow. It is, therefore, systematically 
related to ¢uta and Hepburnii, from both of which it dif- 
fers, apart from its markings, by the much more promi- 
nent double margin of the last ventral segment. 

Occurs at San José del Cabo and Coral de Piedra, 
Sierra el Taste. 


ACMAODERA CRIBRICOLLIS n. sp. Plate viii, fig. 4. 


Moderately elongate and convex, piceous, faintly 
bronzed on head and thorax and beneath, sparsely in- 
vested with short erect whitish hairs. Front convex, 
coarsely and closely punctate, occiput carinate. Thorax 
unicolored, twice as wide as long, widest behind the mid- 
dle, sides arcuate and narrowing to the apex, sinuate be- 
hind the middle, the hind angles (directly from above) 
rectangular, lateral margin very narrow not visible from 
above, disc convex, a vague depression at middle, a faint 
oblique depression each side, a small fovea each side near 
the base, surface densely cribrately punctured and opaque. 
Elytra narrower at base than the thorax at middle, sides 
parallel to middle then arcuately narrowing to base, mar- 
gin serrate, stria with coarse deep, closely placed punc- 
tures, the intervals slightly convex and scarcely wider 
than the strie, each with a row of setigerous punctures, 
surface ornate with yellow in a style similar to vardegata. 
Prosternum coarsely and closely punctate, anterior mar- 
gin truncate. Metasternum coarsely and densely punc- 
tate. Abdomen moderately coarsely and closely punc- 
tate at sides, a little less so at middle. Last ventral with 
single apical margin. Body beneath sparsely cinero- 
pubescent. Length, .40 inch; 10 mm. 

This species is the most obtuse in front of any known 
to me. The thoracic sculpture is of rare occurrence,

densely cribrate and opaque. By the characters used by 
me in an analytical table of the group its position should 
be near cu/ta et seq., all of which are scarcely more than 
half the length of this one, while gemma alone has similar 
thoracic sculpture. By facies the species is best placed 
near obtusa and consors. 

One specimen from Texas; locality unknown. 


ACMAZODERA NEBULOSA DN. Sp. 


Form of cu/ta, piceous, opaque, a feeble bronze lustre 
to the head, thorax and under side, elytra reticulate with 
yellow markings. Antenne with joints gradually wider, 
the fifth not abruptly wider than the fourth. Head crib- 
rately punctured, sparsely hairy, front not impressed. 
Thorax uncolored, a little more than twice as wide as long, 
scarcely narrower at apex than at base, sides arcuate, 
lateral margin entirely obliterated, disc convex without 
median or lateral impressions, a small fovea each side at 
base, surface densely but not deeply punctate, resembling 
crowded reticulations, sparsely hairy. Elytra not wider 
than the thorax, parallel, gradually narrowed at apical 
third and serrulate, disc moderately convex with striz of 
coarse, deep, closely placed, round punctures, nearly as 
wide as the intervals, these flat, somewhat rugose, each 
with a row of punctures bearing a short black hair, sur- 
face opaque piceous with numerous small yellow spots 
intricately joined. Prosternum truncate in front, sur- 
face cribrately punctured. Mesosternum closely coarsely 
punctured. Abdomen subopaque with a somewhat 
rugose aspect, the punctuation relatively coarse and 
dense. Last ventral with single apical margin. Body 
beneath sparsely clothed with short whitish hair. Length, 
.24—.28 inch; 6-7 mm. 

The prosternum being squarely truncate beneath places

the species in the ‘‘truncate,’’ while the structure of the 
antenna and the absence of thoracic margin relate it to 
gemina, from which it differs in its larger size, different 
elytral ornamentation (that species being vittate), and 
the absence of lateral thoracic spot. 

Two specimens from Napa County, Cal. 


ACMAZODERA INSIGNIS nN. sp. 


Form of cu/ta, dull black, opaque, elytra ornate with 
yellow spaces. Antenne as in gemzna, the fifth joint not 
abruptly wider than the fourth. Front convex, obsoletely 
reticulate, sparsely hairy. Thorax unicolored, about a 
third wider than long, very little narrower at apex, sides 
arcuate, lateral margin obliterated in apical half, disc con- 
vex without impressions, the basal fovez relatively large 
and deep, surface reticulately punctured but near the 
sides somewhat cribrate, surface sparsely hairy. Elytra 
not wider than the thorax, sides slightly convergent, ar- 
cuately narrowing at apical third, margin serrulate, sur- 
face striate, strie with moderately coarse punctures not 
closely placed nor deep the intervals slightly convex 
wrinkled and with a row of punctures bearing a short 
seta as in cu/ta, surface ornate with yellow forming a 
space near the base from the first to fifth striz extending 
nearly a third toward apex emitting a branch under the 
umbone, a narrow band at middle oblique backward from 
the suture, a spot, single or divided in front of apex, 
a smaller spot at apex. Prosternum truncate, indistinctly 
coarsely punctate, the flanks reticulate. Metasternum 
with shallow reticulations bearing elongate scales. Ab- 
domen indistinctly reticulate, and with elongate scales 
those at the sides white, at middle yellow. Last ventral 
with single apical border. Length, .16 inch; 4 mm. 

By the prosternum and structure of the antenne this

species is related to gemzna and nebulosa, and is remark- 
able in having the vestiture of the under side scale-like 
and not hairy. 

One specimen found on cactus, San Raymundo. 


ACMZODERA DELUMBIS DN. sp. 


Closely resembling 97édu/a in form and coloration, dif- 
fering as follows: Thorax more coarsely and closely 
punctate. Elytra with a row of five yellow spots on each 
side, centering on the fourth interval, a row of three spots 
on the ninth or widest interval also yellow, red in g7bdu/a, 
a marginal row of four yellow spots. Prosternum as 
in g7bbula. Metasternum at sides coarsely and moder- 
ately closely punctate, sparsely hairy. Abdomen rather 
finely punctate not much more closely at sides than at 
middle, the pubescence at sides sparse and not conspicu- 
ous. Last ventral as in gzbdula. Length, .47 inch; 12 
mm. 

The most conspicuous differences are that in this spe- 
cies the sides of the abdomen are not conspicuously pu- 
bescent and the sides of the elytra have the spots yellow 
and not red. The last named character may not be per- 
manent, the first is valid and not sexual. 

Two specimens from Arizona; others in the National 


Museum at Washington. 


AGRILUS INEPTUS N. Sp. 

Similar in form to acutipennis or pulchellus, bluish 
green or blue as in the former, scarcely shining. Head 
closely punctate, front deeply impressed, a pubescent 
space between the antennez at base. Thorax a little 
wider than long, 
arcuate, hind angles obtusely carinate, a moderate median 


slightly narrower at apex, sides feebly

lum not carinate. Elytra slightly sinuate behind the 
humeri, the apices obtuse scarcely visibly serrulate, sur- 
face closely submuricately granulate. Body beneath 
similar in color to the upper surface. Prosternum mod- 
erately coarsely punctured, the sides of metasternum 
more coarsely, abdomen more finely and less closely 
slightly undulating on the first two segments. Spaces of 
white pubescence are found along the under margin of 
prothorax, the mes-epimera, outer side of metasternum 
and cox plate and at the front angle of each ventral 
segment. The suture between the first two ventrals 
well marked at both sides. Length, .35 inch: g mm. 

This species has the antennz serrate beginning at the 
fourth joint, the lower portion of the bifid claw not 
strongly inverted, the pygidium has no projecting carina, 
thorax slightly impressed at middle, the suture between 
the first two ventrals plainly visible at the sides. It 
is therefore closely related to pulchellus and Walsing- 
hamt, and differs from the former by the obtuse pygid- 
ium and the uniformly colored elytra and from the latter 
by the absence of pubescent spots.

PLATEROS SANGUINICOLLIS n. sp. 


Black, thorax and scutellum bright red. Disc of thorax 
irregular showing a tendency to approximate the orna- 
mentation of Eros, the hind angles slightly prominent ex- 
ternally. Elytra finely costate as usual in Plateros, the 
intervals feebly reticulate. Body beneath more shining 
than above. Legs black, anterior femora at base yellow. 
Length, .20 inch; 5 mm. 

In the female the antenne are shorter than in the male, 
the joints 4 to ro as broad as long.

TELEPHORUS DECIPIENS N. sp. 


Black, moderately shining, sparsely pubescent, thorax 
reddish-yellow with a median triangular space, the base 
anterior. Thorax wider than long, scarcely perceptibly 
punctate, a slight median depression near the base, on 
each side of which the disc is more convex. Elytra sca- 
brous, smoother at base. Body beneath and legs black. 
ength, .2S inch; 7 mm: 

In this species the claws are similar on all the feet and 
broadly obtusely toothed at base. It belongs to LeConte’s 
division A (Trans: Am. Ent: Soc., 1x; 168i, ps 52) 9nd 
by the broad thorax must be placed near denétiger. It, 
however, has considerable superficial resemblance to ore- 
gonus, but differs in the form of the claws. 

San Pedro Martir Mountains. 


POLEMIUS LANGUIDUS n. Sp. 


Oblong, broader behind, yellow slightly reddish anten- 
ne, tibia and tarsi with the last two ventral segments pic- 
eous. Head smooth, a darker band between the eyes. 
Thorax one-half wider than at apex, sides arcuate gradu- 
ally rounding, these from middle to base slightly sinu- 
ous, hind angles distinct but obtuse, disc smooth a slight 
convexity each side of the middle of the base. Elytra 
scabrous with two fine costa on each within the um- 
bone. Body beneath yellow, the last ventral entirely 
piceous the fifth yellow at middle. Length, .47 inch; 
imyeioehaele 

The unique before me is a female and it differs from 
all our species in its color. 

From southern California, probably near San Diego. 
This is the first indication of the genus on the Pacific 
Coast.

ATTALUS SETOSUS n. sp. 

Above in great part red, a median thoracic space sud- 
denly constricted at base, the scutellum and space each 
side piceous. Antennz slender feebly serrate, piceous, 
the three basal joints in part paler. Head oval, not ros- 
trate, piceous except at mouth. Thorax transversely 
oval, sparsely finely punctate and with fine short pubes- 
cence. Elytra slightly wider behind, very sparsely finely 
punctate, with extremely minute pubescence and with 
short erect black seta sparsely scattered. ‘Body beneath 
and legs black, abdomen red. Length, .10 inch; 25 
mm. 

This species bears some resemblance to varieties of 
humeralis, but differs from that and any other species in 
our fauna by the sete: which are found on the elytra. 

San José del Cabo. 


ATTALUS UNICOLOR nf. sp. 


Piceous, distinctly bronzed, moderately shining. An- 
tenne slender, feebly serrate, piceous, four basal joints 
pale beneath. Head oval, not rostrate. Thorax trans- 
versely oval, moderately convex, minutely alutaceous, 
sparsely punctate. Elytra slightly wider behind, surface 
slightly scabrous, with sparsely placed short, black, erect 
hairs. Body beneath black, slightly bronzed. Femora 
except at knees and the posterior tibia black, anterior 
and middle tibiz partly, tarsi entirely testaceous. Length, 
.08 inch; 2 mm. 

This species is notable in its uniform color with bronzed 
surface, resembling in this respect some J/alachius. 

One male. La Chuparosa, near San José del Cabo. 


CYMATODERA PURPURICOLLIS n. sp. 


Brownish, head and thorax metallic blue, the latter 
more distinctly so. Antenne slender, joints three to

eleven not differing notably in length, the second very 
little shorter. Head oval, moderately closely but not 
deeply punctate, surface sparsely pilose. Thorax one- 
half longer than wide at base, broader at apex with the 
usual broad constriction in front of and behind the mid- 
dle, at base bituberose, surface nearly smooth with faint 
traces of transverse wrinkles and sparsely scattered fine 
punctures bearing erect hairs. Elytra not wider at base 
than the thorax, body apterous, sides gradually divergent, 
apices very obtuse, surface with striae of moderately 
coarse not closely placed nor deeply impressed punctures 
which become obsolete at the middle near the suture, but 
extend two-thirds to apex near the sides, intervals with 
very sparsely placed fine punctures bearing erect hairs, 
color pale brown with a narrow yellow band with irregu- 
lar edges extending slightly arcuately outward and back- 
ward from the suture. Body beneath brownish. Meso- 
sternum coarsely punctured. Abdomen indistinctly punc- 
tured, a yellow spot at the side of each segment. Legs 
brown, femora at base, tibiz and tarsi paler. Length, 
4Oinchs 11.Simim: 

Male.—Ventral segments three to five broadly emargi- 
nate and successively more deeply, sixth ventral semi- 
circularly emarginate. Last dorsal narrower than the 
ventral, truncate at tip with an acute notch at middle. 

This species must be placed near ovzfennis and angus- 
tata, the former of which it resembles in elytral marking 
and sculpture. It differs from either in the comparatively 
smooth thorax with distinct metallic surface lustre, a 
character unknown in any North American species.

three transverse narrow yellow bands, the anterior turn- 
ing down along the suture. Antenne entirely black. 
Head oval, not closely punctate, sparsely hairy, palpi 
pale. Thorax oval, as wide as long, apex truncate, sides 
arcuately narrowing to the basal constriction, disc con- 
vex, a slight median depression at base and a faint post- 
apical constriction, surface coarsely punctured, the punc- 
tures rounded at the sides but less dense at middle. Ely- 
tra parallel, the apices truncate, sutural angle distinct, 
surface with coarse cribrate punctures somewhat in striz, 
and short erect black hairs; color dull blue-black with 
three fascia, the anterior beginning with a broad base at 
the humerus extends inward leaving the base then turn- 
ing abruptly parallel with the suture, a second fascia at 
middle, narrow, very slightly arcuate, the third fascia one- 
fourth from apex, slightly arcuate. Sides of metaster- 
num and the posterior edges of segments 2—3—4 at sides 
with moderately long white hair. Abdomen quite smooth. 
Legs black with blue green surface lustre. Length, .38 
inch; 9.5 mm. 

This insect is allied to //wstrzes Horn (Trans. Am. Ent. 
DOC..8i) L676, p. 231) and might teven bean extreme 
form of that, but the uniform coloration of the specimens 
of 7//ustr7is make it advisable to name the present form. 
In zl/ustr7s the antenne, except the last three joints, are 
rufo-testaceous, as are also the legs; the basal band keeps 
close to the margin and extends down the suture, the 
middle band decidedly arcuate and the posterior very 
oblique. 

One specimen, El] Chinche. 


HypDNOCERA OMOGERA DN. sp. 


Form of dzscordea, color black with a humeral yellow 
white spot (the umbone black), or with the white form- 
ing a transverse band immediately behind the umbone. 


384 CALIFORNIA ACADEMY OF SCIENCES. 


Antenne entirely pale. Head moderately closely but not 
distinctly punctate. Thorax broader than long, sides 
strongly arcuate with a short apical and longer basal nar- 
rowing in the usual manner, surface scabrous. Elytra 
wider at base than the thorax, slightly narrowing to apex, 
margin serrate, apex very obtuse, surface shining coarse- 
ly punctured the punctures well separated except in a 
space one-third from apex where the punctures are fine, 
more crowded and with the pubescence, irregular form- 
ing a Closer fascia. Body beneath black, feebly shining. 
Legs slightly variable, but the tendency is to have the 
anterior and middle legs pale, the posterior piceous. 
Length, 14-inch; 3:51. 

The species of Hydnocera are so variable in color and 
so difficult to describe sufficiently that it seems hardly 
proper to indicate new species in an isolated manner un- 
til the genus has undergone a systematic study. Ina 
faunal list like the present essay there is a slight excuse 
for description. ‘The species above named has the form 
and general appearance of Awmeralzs, but with elytral 
punctures of pa//zipennis.

each side of the middle in front and also at base. Ely- 
tra densely finely punctulate, the pubescence forming a 
larger triangular area beginning at the humerus extend- 
ing beyond the middle, the apex reaching the suture one- 
third from base, the scutellar area spotted with white, the 
apical third irregularly marmorate, the space at middle 
third almost nude. Body beneath black, densely punc- 
tulate and cinereo-pubescent. Length, .25 inch; 6.25 
mm. 

One specimen collected in western Nevada by Mor- 
rison; others by Schwarz at Brightons, Utah. 

A prettily ornamented species and easily known there- 
by. Its most striking peculiarity is in the form of the 
antenne. The normal form of antenne in Xestobium is 
to have the last three joints triangular and larger than 
those which precede, the funicular joints slender. In the 
present species there are properly but three funicular 
joints, the third joint of the antenne longer than the sec- 
ond or fourth, fourth shorter than second, fifth twice as 
long, narrowly triangular, sixth short, triangular, seventh 
similar to the fifth, eighth similar to the sixth, ninth and 
tenth like the seventh, eleventh a little longer. When 
the genera of Anobiini have been released from the con- 
fusion in which they appear to be at the present time this 
species may be separated from Xestobium, or, as the ge- 
nus will then be called, Anobium. 


CTENOBIUM CINEREUM D0. sp.

cence abraded from their summits, surface densely finely 
punctured. Body beneath as above. Length, .36 inch;

The specimen before me is probably a male, the last 
ventral is very obtuse with a shallow emargination extend- 
ing from side to side. 

Collected in southwestern Texas, near the Rio Grande. 


TRICHODESMA SELLATA DN. sp, 

Cylindrical, rather more oblong than g7dosa, piceous 
black, densely clothed above with a white pubescence, 
dense, like a spider-web, a large saddle-shaped space 
common to both elytra of brownish pubescence. An- 
tennz ferruginous. Head densely pubescent. Thorax 
broader than long, 
uately narrowing at the middle, hind angles distinct, disc 


sides arcuate in front, suddenly sin- 


strongly gibbous, an impressed line from the apical mar- 
gin to the summit of the gibbosity, surface coarsely punc- 
tured, the pubescence forming denser reticulations, the 
summit of the gibbosity with short, stiff, brown hair. 
Elytra densely pubescent, concealing the sculpture, in 
great part ashy white and web-like with a large saddle- 
shaped space of brown pubescence and with short erect 
hairs sparsely placed similar in color to the surface from 
which they arise, also two arcuate series of erect brown- 
black hairs forming brushes, the one series one-third 
from base, the second one-third from apex, each series 
composed of three brushes on each elytra. Body be- 
neath densely pubescent, the pubescence simple and not 
web-like. Length, .29 inch; 7.5 mm. 

This species differs from every other known to me by 
the form of the thorax. The vestiture is remarkable. 

One specimen, El Taste.

TTRICHODESMA SORDIDA 0. sp. 

Cylindrical, oblong, more than twice as long as wide, 
black, head and thorax with dirty yellow pubescence, 
elytra with a band of same along the base, a very narrow 
sinuous band at middle and an irregular apical space of 
same color. Antenne black. Head black, punctuation 
concealed. Thorax broader than long, sides arcuate in 
front, slightly sinuate in front of the hind angles, the lat- 
ter distinct, disc gibbous behind the middle, a slight sul- 
cus from the apical margin to the summit of the gibbos- 
ity, surface distinctly granulate and not densely clothed 
with dirty yellowish pubescence and with intermixed 
short, black erect hairs, but without brush at the summit 
of the gibbosity. Elytra but little wider than the thorax, 
the surface with irregular striz of coarse, deep, not closely 
placed punctures and clothed with velvety black pile 
arranged in quite small spots, a dirty yellow band com- 
posed of spots across the base, a sinuous indistinct band 
at middle and a space near the apex of similar pubes- 
cence. Body beneath black, subopaque, surface gran- 
ular dashed with recumbent, dirty yellow pubescence. 
Meneth, 2301nchi;) 7.5 mun. 

This species is similar in form to se//afa, being more 
than twice as long as broad, differing in having the sides 
of the thorax less sinuate behind the middle. It differs 
from all our species in having no brush-like tufts at the 
summit of the gibbosity of the thorax.

whitish pubescence. Antenna brownish. Head piceous, 
sparsely granulate and clothed with ferruginous pubes- 
cence less abundant at middle. Thorax one-half wider 
than long, sides regularly arcuately narrowing to base 
without sinuation, the hind angles obliterated, disc gib- 
bous at middle, surface rather closely granulate, densely 
clothed at sides with whitish web-like pubescence, the 
middle third nearly naked except the brushes of black 
hair at the summit of the gibbosity. Elytra wider than 
the thorax, with coarse punctures irregularly arranged in 
striz with small patches of granules irregularly placed, 
more evident at base, surface indefinitely and sparsely 
clothed with short brownish pubescence with small whitish 
patches irregularly placed, small tufts of short erect hair 
form two series, the first of three patches beginning at 
the umbone extending obliquely backward to the suture, 
the second series one-third from apex, strongly arcuate 
on each elytron of four patches each side. Body beneath 
not densely granulate, clothed with short yellowish pubes- 

cence. Length, .24 inch; 6 mm. 

This species is known by its form and the compara- 
tively scanty vestiture of the elytra. ‘The above descrip- 
tion was written under the impression that the species 
was new, aS many important points were passed in the 
description by Capt. Casey. 

Oregon, northern California, Santa Cruz and Alameda. 

The species of Trichodesma of Boreal America may 
be separated as follows: 

Form fully twice as long as wide; sides of thorax sinuate in front of hind 
angles; last three joints of antennew together much longer than the 
preceding joints. 

Sides of thorax abruptly and deeply sinuate; vestiture of surface dense.

Sides of thorax feebly sinuate; vestiture sparse. sordida. 


COLEOPTERA OF BAJA CALIFORNIA. 389 


Form iess than twice as long as wide; sides of thorax arcuately narrowing 
to base without sinuation; last three joints of antenne together not 
longer than the preceding joints. 

Vestiture of surface rather dense and of whitish pubescence in great 


part. grbbosa. 
Vestiture of elytra not dense, surface not concealed, a whitish border 
at base and a small white spot at declivity. cristata. 


The antennal character is to a certain: extent sexual, 
the males having the last three joints longer than the fe- 
males, but as used above (in a secondary position) the 
antennz are in both sexes longer in the oblong group 
than in the shorter forms. The tooth of the claw is more 
acute in the shorter species. 

The four species above recorded all belong to different 
faunal regions—evbbosa from the regions east of the Mis- 
sissippi; sordéda, Texas; cristata, from the California 
region; and se//ata, from the Peninsula of California. 


‘TRIPOPITYS TENUILINEATA n. Sp. 


Cylindrical, brown, subopaque. Antenne pale, the 
basal joint piceous. Head moderately closely punctate, 
sparsely clothed with ochreous pubescence. Thorax 
broader than long, narrower in front, sides strongly ar- 
cuate, margin explanate, disc convex, a faint median im- 
pression and a feeble oblique impression each side reach- 
ing the base, surface roughly punctate but not densely 
and somewhat smoother in the impressions, surface 
sparsely ochreo-pubescent. Elytra moderately closely 
and irregularly punctate, indistinctly clothed with ex- 
tremely fine ochreous pubescence which forms fine 
denser lines extending from the base nearly to the apex, 
a sutural line, one from the umbone, two between these 
on the disc, with an oblique scutellar line, a line external 
to the umbone. Body beneath paler than above, very 
finely densely punctured and with extremely fine pubes- 
cence. Length, .20 inch; 5 mm. 


390 CALIFORNIA ACADEMY OF SCIENCES. 


This insect looks far more like an Oligomerus than 
Tripopitys, but the serrate antenne, the depressed meso- 
sternum and the excavate metasternum have induced me 
to place it in the latter genus. The only characters in 
which it differs from that genus are the elytral sculpture 
and the more explanate sides of the thorax, in the latter 
respect resembling Ernobius. The specimen before me 
is a female, and the antenne are equally serrate from the 
third to the tenth joints, eleventh longer. The elytral 
sculpture and ornamentation make it an easily recognized 
species. 

Occurs in Oregon. 

HEMIPTYCHUS ESTRIATUS N. sp. 

Oblong. oval, piceous black, feebly shining, surface 
finely clothed with short indistinct pubescence. Head 
and thorax not visibly punctate. Elytra not visibly punc- 
tate except under microscopic power, the lateral striae en- 
tirely obliterated. Body beneath not visibly punctate. 
Abdomen sparsely punctate, opaque, finely pubescent. 
Length, .18 inch; 4.5 mm. 

This species is remarkable in its large size and almost 
entire obliteration of sculpture. 

San Fernando. 

An examination at this time demonstrates that as the 
genera are now recognized several species formerly 
placed by Dr. LeConte in Catorama must come to Hem- 
iptychus. These are sectans, obsoleta and punctulata. 
These will form a group by themselves, while odso/etus 
with faint striz is the link with the striate group. The 
species are closely related among themselves, but the fol- 
lowing brief table will enable them to be separated: 
Elytra very obviously punctate even with moderate power; color piceous 


black. sectans. 
Elytra scarcely punctulate; color brown. 


COLEOPTERA OF BAJA CALIFORNIA. 3901 


Scarcely longer than broad. latus. 

One-half longer than broad. estriatus. 

With sectans I have united punctulata. These were 
originally described trom uniques, and the character based 
on size, which seems to be the only one separating them, 
has entirely disappeared in a series of twenty. The name 
latus is proposed for odso/etus, as there is at present a spe- 
cies with the latter name in Hemiptychus. 

HEMIPTYCHUS ROBUSTUS DN. sp. 

Oblong oval, moderately densely clothed with ochre- 
ous pubescence which conceals the piceous color of the 
surface. Antenne pale. Head minutely punctulate. 
Thorax minutely densely punctulate with coarse punc- 
tures widely scattered but closely placed near the hind 
angles. Elytra similarly punctulate, the slightly larger 
punctures more numerous and more evident near the 
apex, the marginal striae deep, extending from the apex 
nearly to the middle. Body beneath similarly punctured 
to the upper surface, the coarser punctures of the abdo- 
men more abundant and more evident. Length, .18 
inch; 4.5 mm. 

A number of specimens of this large species have been 
seen. At first glance they resemble estriatus, although 
more coarsely pubescent. It is at present the largest spe- 
cies known with the elytra striate at sides near the apex. 

Southwestern Texas, near the Rio Grande. 

The genus Hemiptychus threatens to be very trouble- 
some. A number of species still exist without. names, 
but it has not been thought advisable to name any but 
those necessary, in advance of any general revision of 
them. 


CERACIS SIMILIS Nn. sp. 


Cylindrical, castaneous, the elytra slightly darker at 
base, glabrous, distinctly punctate. Antenne pale, the 


392 CALIFORNIA ACADEMY OF SCIENCES. 


club darker. Thorax as broad at base as long, narrower 
in front in the 2, surface finely not closely punctate, a 
smooth median line posteriorly. Elytra more coarsely 
punctate than the thorax. Body beneath sparsely punc- 
tate. Legs pale. Length, .05 inch; 1.25 mm. 

Male.—Head smooth, concave, margin of clypeus re- 
flexed and emarginate, apical edge of thorax at middle 
reflexed in a short lamina which is emarginate. 

Fremale.—Front convex, sparsely minutely punctate, 
minutely alutaceous. Clypeus’and margin of thorax not 
elevated. 

This species is probably closely related to guadricornts 
Ghm., but the description is so brief as to render it un- 
safe to consider the two identical. 

Coral de Piedra, Sierra el Taste. 


RHIPIDANDRUS PENINSULARIS Nn. sp. 


Cylindrical, brown, subopaque. Antenne pale. Head 
reticulate, densely punctured between the eyes and pu- 
bescent, clypeus smooth. Thorax broader than long, 
slightly narrower in front, sides feebly arcuate, disc reg- 
ularly convex, closely reticulate. Elytra not broader 
than the thorax at base, broadly sulcate, sulci slightly 
wrinkled, intervals finely subcostiform. Body beneath 
very coarsely not closely punctate. “Length; .13 ich; 
e:5 iin. 

The most striking difference between this species and 
paradoxus is in the form of the antenne. In the latter 
species the joints 5-10 are produced in a long branch, 
while in the present species the fourth and fifth joints are 
simply triangular, 6-10 transverse, twice as wide as long, 
eleventh transversely oval. This structure is the same as 
that described for Eutomus, a genus at present placed in 
the Scolytide. 


COLEOPTERA OF BAJA CALIFORNIA. 393 


In paradoxus the thorax is rather coarsely and densely 
punctured and the prosternum finely carinate; in fenzn- 
sularts there is no Carina. 

Coral de Piedra, Sierra el Taste. 


CANTHON OBLIQUUS DN. sp. 

Black, semi-opaque, oval narrowed behind as in xzgrz- 
cornis, surface not punctate nor granulate. Clypeus 
notched at middle not forming teeth, the sides oblique, 
scarcely perceptibly arcuate. Thorax smooth, disc con- 
vex with an ante-scutellar depression, a median impressed 
line from middle to base. Elytra arcuately narrowing 
almost from the humeri, the striz almost entirely obliter- 
ated, surface very finely granulate-alutaceous. Pygidium 
flat, alutaceous. Body beneath extremely finely aluta- 
ceous. Length, .32-.38 inch; 8-9.5 mm. 

In addition to the above, the following characters may 
be added that the relationship of the species may be traced 
in the tabular scheme given by Baron Harold (Berl. Ent. 
Zeit., 1868, p. 11). Posterior tibiz slightly arcuate, with 
one spur, the femur not punctate nor with marginal 
line. Anterior tibiae obliquely truncate. Prosternum be- 
neath without transverse carina and without sub-marginal 
tooth. From these characters it would seem to be allied 
to ¢restes, which however has no thoracic depression. 
Among the Boreal American species it is probably best 
placed near /evzs. It differs notably from any of our 
species in having the sides of the clypeus oblique and not 
arcuate. The male has the spur of the front tibiz 
broader at tip, truncate and emarginate. 

Occurs at Pescadero and Sierra el Chinche.

and deeply punctured. Apex of clypeus reflexed, acutely 
emarginate, the angles acute. Thorax coarsely sparsely 
punctate, smoother at sides and base. Elytra coarsely 
sparsely and irregularly punctate. Body beneath sparsely 
punctate and hairy. Length .14-.16 inch; 3.5-4 mm. 

Male.—Anterior tibia without spur. Pygidium vertical 
or slightly inflexed, regularly convex, clothed with whitish

cave near apex. discolor. 

Surface dull. Clypeal teeth acute. Pygidium of female bi-impressed.

The differences between this species and floralzs are 
almost generic and are as follows: 

Sides of clypeus parallel; upper tooth of anterior tibia small; anterior 
claws simply cleft. floralis. 

Sides of clypeus convergent; upper tooth of anterior tibia well developed; 
anterior tarsal claws dissimilar, the anterior one with a lobe-like tooth 
at base, both claws cleft at tip. convergens. 

It is probable that all the specimens seen are males, as 
none of them have any anterior tibial spur and the pyg- 
idium is nearly vertical. 

As classifications now stand, Oncerus is fairly well 
placed in the Chasmatopterides as defined by Lacordaire, 
but the same group as constituted in our fauna (Classifi- 
cation, p. 249) is not anatural one. Podolasia and Acoma 
should be separated by their simple claws. 

Chnaunanthus has a distinct labrum concealed beneath 
the clypeus, while Oncerus has the labrum connate with 
clypeus, asin Phyllotocus and Cratoscelis more especially, 
as well as in Serica. 

There seems to be a great need at the present time of 
a revision of the relationships of many genera at present 
placed vaguely among the Melolonthide. 

Wir ies Wee Bates remarks, (Biol; vole 2, pt:25p)129), 
in describing Aporolaus: ‘‘An interesting generic form 
* * * demonstrating that the mouth-structure (espec- 
ially the free bilobed ligula) is more to be relied upon 
than the position of the abdominal spiracles as indications 
of natural affinity in this portion of the Lamellicorn series.”’ 

In emitting this opinion Mr. Bates seems to have been 
influenced by a reverence for the classification then ex- 
isting. From my own studies, made necessary by my 
defense of the position of Pleocoma and by a critical ex- 
amination of very many obscure genera of Lamellicorns, 
it seems clear that the free bilobed ligula and laparostict 
spiracles are concurrent characters. 


396 CALIFORNIA ACADEMY OF SCIENCES. 


There are at present a number of genera with a more 
or less membranous and free ligula associated with vari- 
ous tribes of Melolonthide, such as Phyllotocus, the 
Pachytrichides, Aclopides and Chasmatopterides, which 
might form groups between the Laparosticti and Pleuro- 
sticti, as at present arranged, and thereby render the 
transition less abrupt. The Pachycnemides occupy just 
such a position as placed by Lacordaire. ‘The Chasma- 
topterides and Aclopides are true laparosticts, while 
Pachytrichia seems far better placed near Glaphyrus, as 
Hope, Burmeister and Westwood have suggested. Phy]- 
lotocus, a laparostict, is about as badly placed among the 
Sericides. 

Some interesting results will follow a study of the 
Pachypodides. In Pachypus the spiracles are so placed 
as to make it doubtful whether they are truly laparostict 
or not. The entire organization of Pachypus seems to 
relate it to our Pleocoma, an undoubted laparostict, except 
as to the ligula. The larva of Pachypus is badly needed 
to settle its true position in the lamellicorn series. 


DICHELONYCHA PICEA N. Sp. 


Brownish piceous varying to quite pale, without metal- 
lic lustre, sparsely clothed with short semi-erect gray 
hair. Head rather coarsely, moderately closely punc- 
tate. Clypeus nearly smooth, arcuate in front, angles 
obtuse, sides oblique continuous with the gene, the eyes 
not prominent, frontal suture distinct, not impressed. 
Antenne 8-jointed. Thorax nearly twice as wide as 
long, sides rather strongly arcuate, all the angles very 
obtuse, disc convex without sulcus sparsely punctate es- 
pecially at middle, a fovea near the middle of each side. 
Elytra vaguely costate, coarsely and irregularly punctate. 
Body beneath very sparsely punctate and hairy. Legs 
somewhat pale. Length, .30 inch; 7.5 mm. 


COLEOPTERA OF BAJA CALIFORNIA. 397 


This species does not differ especially in form from 
the others. The clypeus is, however, more arcuate in 
front, the antenna 8-jointed and the tibial teeth feebly 
indicated. 

Two specimens, San José del Cabo and El Chinche

SERICA PILIFERA N. SP. 


Oblong ovate, pale brown, dull, surface with semi-erect 
fulvous hairs. Head opaque, impunctate, clypeus coarse- 
ly punctate, more shining, the apical margin moderately 
reflexed with rounded angles, broadly but slightly emar- 
ginate, a very slight incisure each side. Thorax more 
than twice as wide as long, slightly narrower at apex, 
sides feebly arcuate, hind angles rectangular, surface 
dull, sparsely indistinctly punctate, margin fimbriate, disc 
with semi-erect fulvous hairs sparsely placed. Elytra 
very vaguely subsulcate, the intervals slightly convex, 
the sulci irregularly punctate, the punctures bearing a 
semi-erect hair. Body beneath dull, sparsely punctate 
and hairy. Length, .32 inch; 8 mm. 

This species may be known by its hairy surface, the 
hairs of the elytra being vaguely arranged in rows in the 
sulci.

DIPLOTAXIS PUNCTULATA N. Sp. 


Oblong-oval, piceous black, moderately shining. Cly- 
peus hemi-hexagonal, the angles well rounded, feebly 
emarginate, surface cribrately punctate. Head coarsely 
and densely punctate, a smooth vertical space. Thorax 
twice as wide at base as long, slightly narrowed in front, 
sides feebly arcuate, disc regularly convex, coarsely not 
closely punctate, intervals with few very minute punc- 
tures. Elytra with striae in pairs of coarse punctures as 
in ¢ristés, the intervals coarsely not closely punctate, the

interspaces between the punctures finely punctulate. 
Pygidium coarsely closely punctate. Body beneath 
coarsely punctate, sparsely on the abdomen with a short 
yellow hair from each puncture. Length, .56—-.60 inch; 
I4-15 mm. 

The largest species of the genus known and of more 
robust facies than /77s¢7s and the allied forms, with which 
it should be associated. It differs from all of that group 
by the presence of the minute punctures of the elytra.

LISTROCHELUS CARMINATOR Nn. Sp. 


Oblong, nearly parallel, rufo-castaneous, head and 
thorax darker and more shining, elytra dull faintly prui- 
nose. Antenne rufescent, club paler. Head coarsely 
closely punctured, clypeus hemi-hexagonal, feebly emar- 
ginate with rounded angles. Thorax less than twice as 
wide as long, slightly narrower in front, sides feebly ar- 
cuate margin crenulate and fimbriate, disc convex coarsely 
moderately closely punctate, more sparsely along the 
sides and base. Elytra more finely, less deeply punc- 
tured than the thorax, the cost very indistinct. Body 
beneath punctate, with long yellow hair. Abdomen very 
sparsely finely punctate, shining at middle, opaque at the 
sides. Length, .60 inch; 15 mm. 

Male.—Antennal club as long as the funiculus. Claws 
similar on all the feet, pectinate from a single edge with- 
out tooth. Pygidium convex sparsely punctate. Sixth 
ventral large with a broad shallow concavity extending 
from apex to base. 

From the structure of the claws this species is allied to 
puberulus. It differs in that the latter has a very coarsely 
closely punctate thorax, and the male has quite a short 
sixth ventral segment.

CREMASTOCHILUS OPACULUS n. sp. Plate vu, fig. 1. 

Oblong, black, opaque, dorsum very flat. Clypeus 
strongly carinate at middle. Disc of thorax sharply di- 
vided into three regions, anterior angles auriculate, the 
posterior spiniform, sides arcuate, sinuately narrowing 
to the hind angles, base sinuate within the angles, disc 
coarsely punctured, the outer lobes more coarsely and 
closely, the central portion more sparsely and more 
opaque. Elytra flat with punctures in the form of elon- 
gate scratches on the disc, but decidedly punctiform at 
the sides. Body beneath shining with coarse sparse 
punctures. Legs slender. Mentum entire. Length, 
Aqanch; 11 mim. 

Closely allied to sfznzfer, but with the disc of thorax 
more sharply divided and differently sculptured. The 
hind angles of the thorax are not everted. It is also al- 
lied to planzpes, but that has broad thin tibia.

EBURIA CONSPERSA Nn. sp. 


Pale piceo-testaceous, clothed with recumbent fulvous 
pubescence. ‘Thorax transversely quadrate, sides feebly 
arcuate, with feeble post-median tuberosity, disc covered 
with callosities as follows: a median linear from apex to 
base, a broader one each side from base toward apex, a 
small oblique one between these in front, one near each 
front angle. Elytra rugulose, with scattered foveiform 
punctures, one ivory spot at base, two behind the middle, 
the outer longer, these spots on the line of nude costa, 
the outer one nearly entire, the inner abbreviated, elytra 
at apex rounded, a sutural spine. Body beneath sparsely 
pubescent. Femora not spinose at apex. Length, .67

ACYPHODERES DELICATUS Nn. Sp. 


Form slender. Head yellowish, cribrately punctate. 
Antennz similar in color, half the length of body, stouter 
externally, scape coarsely punctate, third joint nearly as 
long as the next three. Thorax as broad as long, wider 
at middle, sides regularly arcuate, disc convex, densely 
punctate, very finely pubescent, a feeble median smoother 
line and vague oblique umbone either side, color reddish- 
brown, base and apex bordered with black. Scutellum 
flavo-pubescent. Elytra pale brownish testaceous, yel- 
low-white along the base, form subulate, sparsely punc- 
tate and shining, although somewhat rugose near the 
base. Prothorax beneath black, densely punctate. Meta- 
thorax sparsely punctate and pubescent, with denser 
hair anteriorly. Mesopleure and apex of met-episternum 
densely flavo-pubescent. Abdomen pale piceo-testaceous, 
sparsely punctate and with few short hairs. Legs rufo- 
testaceous, the basal half of the tiba and femora yellow- 
white. Length, .45 inch; 11 mm. 

The introduction of this genus into our fauna requires 
that an additional tribe be added to the table as given on 
page 276 of the Classification, and placed near the Ancy- 
locerini and Rhopalophorini, from both of which tribes 
the new one will be distinguished by having the anterior 
coxee cavities closed behind. The tribe is named Rhino- 
trogides by Lacordaire. 

The species above described resembles sezavzs Bates 
(BiolS viep- 290, pls x tie. 20), but isvsmaller and dif- 
ferently colored.

SPHENOTHECUS BASALIS N. sp. 


Piceous black, moderately shining, a very small hair 
in each puncture of dorsal surface, the basal region of 
the elytra and femora red. Vertex coarsely punctate at 
the sides. Thorax oval, narrower in front, apex and 
base truncate, sides arcuate, disc convex, a slight trans- 
verse depression in front of the base, surface with coarse 
transverse punctures not closely placed, the median line 
and depressed basal region smoother. Elytra coarsely 
irregularly punctate, the punctures becoming fewer and 
closer near the apex, apices acutely rounded, a small 
spine at the suture, a larger spine externally. Body be- 
neath sparsely cinereo-pubescent. Legs black, femora 
red, the condyles of hind femora dentiform. Length, 
.48-.56 inch; 12-14 mm. 

This species is congeneric with .S. s¢ra/7s—in other 
words, is a Sphenothecus as restricted by Le Conte. 
The genus, as admitted by Mr. Bates, is certainly a com- 
posite one. This species differs from swturalis in color 


and vestiture; the scutellum is nude.

OPHISTOMIS VENTRALIS n. Sp. 


Slender. Head black, closely punctate. Thorax red 
or black, conical, longer than wide at base, apex con- 
stricted, sides compressed behind the middle, disc very 
convex, very sparsely and finely punctate, hind angles not 
explanate. Elytra wider at base than the thorax, humeri 
prominent, sides obliquely narrowing, apex obliquely 
emarginate-truncate, the angles acute, disc coarsely and 
deeply not regularly punctate, punctures finer toward 
apex. Pro- and mesosternum black. Metasternum and 
abdomen red, very sparsely finely punctate, not pubes- 
cent. Legs black, the under side of hind femora at base 
usually red. Length .42-.47 inch; 11-12 mm. 


402 CALIFORNIA ACADEMY OF SCIENCES. 


The vestiture of the upper side consists of very short 
black hairs arising from the punctures. This species is 
allied to rujiventr7s Bates from Nicaragua, but differs in 
its almost smooth thorax. 

Ophistomis is barely separable from Leptura, the only 
character being the prolongation of the head into a beak.

CC@NOPCUS NIGER DN. sp. 

Form of Palmerz, black shining, the pubescence ex- 
cessively fine,short, black. Antenne black, joints three 
to seven, annulate with white. Front sparsely punctate. 
Thorax broader than long, angulate at the middle, sides 
in front oblique, behind the angulation forming a cylin- 
drical constriction, surface with coarse punctures along 
the apex and base, very few at middle. Elytra coarsely, 
closely and deeply punctate, near the apex much smoother. 
Body beneath extremely finely pubescent. Length, .67— 
.75 inch; I7-I19 mm. 

This species differs from Pa/merz in the coarser and 
closer elytral punctuation and by the absence of any or- 
namentation by pubescence either above or beneath. 
The two specimens before me are females and have the 
last ventral slightly emarginate, as in Pal/mer7.

PERITAPNIA Nov. gen. 


Middle coxal cavities closed externally, the anterior 
slightly angulate as in Tapina. Middle tibia with a sinus 
externally near the apex. Claws divaricate. Front ver- 
tical, broad, the antenna widely separated at base. Head 
similar in the sexes, not alate. Antenne longer than the 
body in both sexes, one-half longer in the male, joints 
not ciliate, first joint conical, rather stout, second small, 


COLEOPTERA OF BAJA CALIFORNIA. 403 


third as long as first, fourth joint shorter, those following 
about equal in length. Eyes coarsely granulate, very 
deeply emarginate. Thorax strongly angulate at the 
sides. Scutellum not large, semicircular. Elytra wider 
at base than the thorax, apices entire, rounded. Mesos- 
ternum slightly convex. 

This genus contains two species, of which nadzcornis 
may be considered the typical form. The type is some- 
what depressed, but less so than in Tapina, while the 
second species is slightly more convex. The coxe are 
all widely separated, but to aless extent than in Tapina, 
and rather more widely in xwdzcornzs than in the other. 
In the males of both species the anterior femur is slightly 
angulate on the under side one-third from the base, and 
with a small brush of short hairs. No such character 
has been seen in Tapina. 

The relationships of this genus are as difficult to define 
as those of Tapina. It seems, while strongly related to 
Tapina, to connect that genus with the Estolides. Ad- 
mitting the weight which Lacordaire insists should be al- 
lowed for the widely separated coxa, especially the pos- 
terior, there can be no hesitancy in placing the genus 
near Tapina, a view also admitted by Bates by his con- 
sidering nudicornzs a possible Tapina. From the latter 
genus it will be separated by the antenne not ciliate, and 
the similar form of the head in the two sexes. The two 
species are as follows: 


Piceous black, moderately shining, muricate punctures of elytra irregu- 


larly placed. nudicornis. 
Brown, dull, more convex, muricate punctures regularly and evenly 
placed. Sabra.

moderately closely punctate. Thorax much _ broader 
than long, sides strongly angulate at middle, in front of 
angulation the sides are oblique, behind sinuate, surface 
finely punctulate and pubescent with short erect hairs 
arising from sparsely placed coarser punctures. Elytra

hairs arising from muricate punctures equally placed over 
the surface but not in stria. Body beneath and legs 
paler, sparsely finely punctate and pubescent. Length,

The general form in outline is that of a Tapina, but 
more convex, approaching Tetraopes.

TETRAOPES ELEGANS DN. Sp. 


Form of désco¢deus, black, elytra ornate with red, sur- 
face finely cinereo-pubescent, decidedly bluish on the 
thorax, with short black erect hairs intermixed. Anten- 
nee black, the first three joints and the under side of the 
other joints with bluish-cinereous pubescence. Head red, 
scarcely pubescent, sparsely punctate the punctures with 
erect black hairs. Thorax entirely black, very sparsely 
punctate, the umbone abruptly elevated, smooth at its 
sides, coarsely sparsely punctate and hairy on its summit. 
Scutellum black. Elytra coarsely not closely punctate, 
apical third nearly impunctate, color black with a red 
basal band, broader at middle and extending narrowly 
along the sides, behind the middle a triangular red space 
not reaching the suture, umbone black, on each side of 
the suture at the posterior edge of the red band a small

very black spot, the posterior edge of the triangular spot 
bordered with black. Body beneath finely cinereo-pubes- 
cent.. Legs black. Length, .35-.47 inch; 9-12 mm. 

The coloration of the elytra is of a style similar to that 
of dzscotdeus, but the black is more extended. It differs 
especially from that species in having the umbone more 
elevated and more sharply limited, and by the absence of 
the four black spots on the thorax which are so constant 
in our other species.

LEMA FLAVIDA D0. sp. 


Form of ¢rz/zneata, entirely yellow except the antenne, 
tarsi, sutural interval and met-episterna, which are piceous 
black. Head with the usual v-shaped impression and 
small vertical fovea. ‘Thorax constricted behind the mid- 
dle, the dorsal transverse impression not deep, disc ante- 
riorly with a few coarse punctures. LElytra with striz of 
coarse punctures which become finer toward the apex, 
the intervals wider than the striz and with a row of dis- 
tant finer punctures, ninth striz entire. Body beneath 
very sparsely punctate and slightly pubescent. Length,

This species resembles ¢vz/¢neata, and difters from it in 
the absence of the lateral elytral stripe and by the sutural 
stripe narrower.

an acutely impressed v-shaped impression. ‘Thorax 
smooth, constricted at middle, the dorsal transverse 
groove feeble. Elytra with stria of coarse and deep, 
rather distant punctures becoming finer toward apex, the

moderately large, feebly emarginate in front. Maxillary 
palpi moderately stout, the last joint slightly longer than 
the preceding, conical and acute attip. Antenne slightly 
longer than half the body, very slightly thicker toward 
the tip, first joint claviform, second half as long, third 
slightly longer than second, joints 4-10 slightly longer, 
eleventh longer, acute at tip. Thorax without basal or 
longitudinal impressions, the angles distinct. Scutellum 
triangular. Elytra a little wider than the thorax, with 
wide epipleurz. Prosternum narrow between the coxe, 
the cavities closed behind. Met-episterna much narrowed

This new generic name is suggested for a small species 
which I.cannot refer to any of the described genera. It 
is without doubt referable to the Oxygonites of Chapuis, 
and seems most nearly related to Oxygona, but differs in 
having the elytra regularly striate punctate and by the 
entire absence of frontal callosities, the head, in fact, re- 
sembling Systena. The angles of the thorax are tuber- 
culiform and setigerous, as in Oxygona. 

In the arrangement of the Halticini proposed by me

DyYSPHENGES ELONGATULUS n. sp. Plate viii, fig. 8. 


Form of an elongate Longztarsus, color variable from

the eyes which are well separated. Antenne piceous, 
the four basal joints pale. Thorax conical, broader at 
base than long, surface coarsely and moderately closely 
punctate, the intervals densely punctulate surface clothed 
at the sides with ochreous pubescence, the middle brown- 
ish. Elytra conjointly square with rounded corners, reg- 
ularly striato-punctate, the punctures not coarse, intervals

This species belongs to a group in our fauna contain- 
ing but few species which approach the scufel/aris group

of more oblong form. Bruchus is a genus of very diffi- 
cult study, and the results obtained by Dr. Sharp in the 
more numerous species of Mexico are not more satisfac- 
tory than my own published twelve years anteriorly. 

Occurs in Texas. San Julio and San Ignacio.

SPERMOPHAGUS (ZABROTES) SEMICINCTUS 0. sp. 


Quadrate-oval, robust, black, clothed beneath with cin- 
ereous pubescence, above black, variegated with cinereous. 
Antenne feebly serrate, more than half the length of the 
body, black. Front feebly carinate. Thorax nearly 
semicircular with relatively coarse scattered punctures, 
the interspaces densely punctulate, clothed with black 
pubescence, at sides narrowly cinereous, in front of scutel- 
lum a long, narrow, triangular cinereous space branched 
in front, between the middle and sides three other cine- 
reous spots, one of which joins the margin. Scutellum 
white. Elytra striate, striz finely punctate, intervals flat, 
densely finely punctulate, clothed with black pubescence 
an irregular, narrow cinereous band at middle attaining 
the side but not the suture, a few dashes of cinereous on 
alternate intervals in front of and behind this band. Py- 
gidium black with ochreo-cinereous pubescence along its 
anterior border and a conspicuous white line at middle. 
Leneth,..09 inch; 2.25 mm. 

This species differs from all described in our fauna in 
the thoracic markings, and is evidently near to pectoralzs 
of Mexico. 

Drs Sharp (Biel. Cent. Am... vol: v,.p.492) seems 
hardly willing to admit Zabrotes to full generic rank, but 
the feebly or not toothed claws, contiguous front coxa, 
the shorter scutellum, together with the general facies, 
seem to entitle it to recognition. The question, however, 
still remains open whether /z¢zvz/ztzus, the type of the ge- 
nus Spermophagus, may not be the type of the Zabrotes 
group. In that case the latter will truly be a synonym 
and the other larger forms as rodznze, etc., will have a 
new name.

TRIMYTIS OBTUSA DN. Sp. 


Oblong, piceous black, moderately glossy. Antenne 
pale. Head densely and somewhat strigosely punctate, 
middle lobe of epistome obtusely triangular. Thorax 
about twice as wide at middle as long, 
arcuate, base and apex nearly equal, the angles obtuse, 


sides regularly 


moderately coarsely and closely punctate, somewhat stri- 
gose at the sides. Elytra slightly wider at base than the 
thorax, with stria of fine punctures not closely placed, 
intervals irregularly biseriately punctate, the punctures of 
the stria and intervals confused behind the scutellum. 
Pro- and mesosternum very coarsely punctured, the pro- 
pleure strigose. Abdomen moderately coarsely not closely 
punctate. Legs slightly brownish. Length, .15—.18 
inch; 4-4.5 mm. 

Occurs at Sierra Laguna. 

There are now three species of Trimytis known to me, 
which may be separated in the following manner: 
Thorax distinctly wider at base than at apex, hind angles rectangular, an- 

terior angles prominent to the front. 

Middle lobe of epistome squarely truncate, front very little strigose at 
the sides; thoracic punctuation not coarse nor dense; surface mod- 
erately shining. pruinosa. 

Middle lobe of epistome semicircular, front closely strigose; thoracic 
punctuation rather coarse and close; surface subopaque. 

pulverea. 
Thorax scarcely perceptibly wider at base than at apex, hind angles obtuse, 
anterior angles not produced. 

Middle lobe of front obtusely triangular, front not truly strigose but 
with coarse punctures longitudinally confluent; thoracic punctua- 


tion moderately coarse and close; surface moderately shining, less 
on the head and thorax. obtusa. 


From an examination of a typical specimen of Pescen- 
nius villosus Champion, from Mexico, shows that it does 
not differ from Trimytis in structural characters beyond 
the fact that the surface is hairy.

‘ 
EMMENASTRICHUS gen. nov. 


This name is proposed for two species which are in 
all essential respects Emmenastus, except that the surface 
is sparsely clothed with hair more or less erect. This 
genus in its relation to Emmenastus parallels that of Pes- 
cennius to Trimytis, of which mention has already been 
made. 

The two species known to me are— 


Brownish, hairs moderately long; thorax with large round, closely placed 
punctures almost cribrate at the sides. cribratus. 

Piceous, hairs short; thorax with elongate punctures, denser and deeper 
at the sides. erosus. 


In both species the elytral epipleure are punctate, a 
character not observed in Emmenastus. 


EMMENASTRICHUS CRIBRATUS DN. Sp. 


Oblong, similar in form to Ammen. punctatus, brown 
or slightly piceous. Head with coarse, round punctures, 
close but not crowded, each bearing a short yellow hair. 
Thorax not quite twice as wide as long, slightly narrowed 
in front, sides feebly arcuate, anterior angles prominent 
in front, hind angles sharply rectangular, base slightly 
sinuate, surface with coarse, round, closely placed punct- 
ures at sides almost cribrate, each bearing a moderately 
long erect hair. Elytra oblong oval, with stria of coarse 
closely placed punctures, intervals flat irregularly, biser- 
iately finely punctate, all the punctures with an erect yel- 
low hair longer than that of the thorax. Prothorax 
beneath very coarsely cribrate punctate. Meso- and 
metothorax similarly but less coarsely punctate. Abdo- 
men coarsely not closely punctate, surface beneath 
sparsely hairy as above. Femora punctate. Legs sparsely 
hairy. Length, .32-.34 inch; 8-8.5 mm. 

This species might readily be mistaken at first sight 
for an Amphidora; in fact, one was given to me as such. 

San José del Cabo. 


414 CALIFORNIA ACADEMY OF SCIENCES. 


EMMENASTRICHUS EROSUS N. sp. 


Moderately elongate as Ammen. longulus, piceous, dull. 
Head densely coarsely punctate, sparsely hairy. ‘Thorax 
nearly twice as wide as long, apex slightly narrower, 
sides feebly arcuate, base almost squarely truncate, hind 
angles rectangular, apical angles prolonged to the front, 
disc sparsely hairy, coarsely and closely punctate, the 
punctures elongate and densely crowded at the sides. 
Elytra rather obtuse at apex, disc with stria of moderately 
coarse and closely placed punctures, intervals flat, uni- 
seriately punctate, the third and fourth biseriately, all 
the punctures bearing a short, semi-erect fulvous hair. 
Prothorax beneath coarsely punctate, the punctures of 
the pleure coarser than those of the sternum. Meso- 
and metasternum similarly punctate. Abdomen much 
less coarsely and less closely punctate. Body beneath 
inconspicuously hairy. Femora_ sparsely punctate. 
Length, .28anehs. Fem: 

One specimen. San José del Cabo. 


CENTRIOPTERA ANGULARIS n. sp. Plate vii, fig. 4. 


Form more robust than usual in the genus, approaching 
Cryptoglossa. ead wanting in the specimen. Thorax 
trapezoidal, broader than long, sides arcuate in front, 
sinuate behind the middle, the hind angles acute anc 
everted, anterior angles acutely prominent to the front, 
disc moderately convex, a slight depression along the 
base, surface very finely sparsely punctate. Elytra oval, 
approaching the form of Cryftog/ossa, disk slightly de- 
pressed, surface subsulcate with small distant murications 
in the grooves, intervals slightly convex more evidently 
muricate especially at the sides, apex gradually declivous. 
Prothorax beneath slightly wrinkled. Metasternum with 
few coarse punctures. Abdomen very sparsely punctate. 


COLEOPTERA OF BAJA CALIFORNIA. 415 


Legs coarsely closely punctate. Length from apex ot 
thorax to tip of elytra, .83 inch; 21 mm. 

While the absence of the head prevents a certain as- 
signment of the species generically there seems to be but 
little doubt of the correctness of the assumption that itis 
a Centrioptera. It seems to go one step further from the 
general form of the genus than tnfausta toward Crypto- 
glossa. From all our species it differs in having the 
hind angles distinctly everted and the lateral margin in 
front of them slightly reflexed. These characters are 
faintly indicated in some ¢ufausta. 

E] Paraiso. 


ASIDA PLANATA DN. sp. 


Of the exact form of opaca, black, subopaque. Head 
coarsely punctate. Thorax coarsely and closely punc- 
tate. Elytra slightly broader at base than the thorax, 
humeri distinct, the margin at that point slightly reflexed, 
disc transversely flat, the lateral marginal carina very 
nearly reaching the apex, surface even, without costz or 
wrinkles, with sparsely placed small granules each bear- 
ing a minute hair. Prothorax beneath very coarsely 
punctured, granulate each side of the coxe. Entire 
mesosternum and sides of metasternum granular. Ab- 
domen finely sparsely punctate, last two segments more 
densely. Legs closely punctate. Length, .63 inch; 16 
mm. 

In the unique female before me there is a small fovea 
each side of the median line in front of the middle of 
the disc of the thorax. This is probably individual here 
as it is known to be in mordzllosa. 

This species may be known by its resemblance to opaca 
in form, differing in its almost sculptureless elytra which 
are flat in a transverse direction. 

San Francisquito. 


416 CALIFORNIA ACADEMY OF SCIENCES. 


Asida planata belongs to a group of species which 
seems fairly definable. The elytra at base are wider than 
the thorax, the humeri rectangular or nearly so and the 
lateral margin is distinctly reflexed. In repose the hind an- 
gles of the thorax are slightly prolonged over the humeri. 
It will be also observed that the mentum does not com- 
pletely fill the gular emargination and the ligula is nearly 
as distinctly visible as in Branchus. The species belong- 
ing to this group are moderately numerous. In the fol- 
lowing table will be found the species of our fauna to 
which I have added two from Mexico, co//arzs and scutel- 
farts, as a means of adding a good number of other forms 
from that region which belong near those cited: 


Elytra sharply costate, the marginal ridge extending to the apex; hind 
angles of the thorax not everted. 
Elytral costa regular, the outer one not joining the margin. lirata. 
Elytral cost undulating, the outer joining the margin near the humer- 
ous. scutellaris. 
Elytra not sharply costate. 
Marginal ridge of elytra entire, extending from base to apex; hind angles 
of thorax everted. 
Elytra with three lines of wrinkles replacing the cost, disc trans- 
versely convex, more or less shining. mancipata. 
Elytra with slightly uneven and very opaque surface, transversely 
convex. opaca. 
Elytra with transversely flat and almost unsculptured surface, 
planata. 
Marginal ridge of elytra short, humeral; elytra smooth; hind angles of 
thorax not everted. 
Thorax scarcely broader at base than apex and very little wider than 


long. 
Thorax coarsely punctured near the side. guadricollis. 
Thorax at sides smooth. collaris. 
Thorax broader than long, broader at base than apex. polita. 


ASIDA SUBVITTATA 1. Sp- 

Somewhat of the form and facies of ofaca but with 
the elytra more narrowed at base and expanded pos- 
teriorly, dull black, elytra with three vitte of minute 


COLEOPTERA OF BAJA CALIFORNIA. 417 


granules each with a minute spine-like hair. Head mod- 
erately coarsely, not densely punctured. ‘Thorax broader 
than long, slightly narrower in front, sides feebly arcuate 
with a slight sinuation posteriorly, the hind angles acute, 
disc moderately convex, a faint trace of a median groove, 
coarsely and closely punctured, denser at the sides. 
Elytra broadest behind the middle, humeri distinct but 
not rectangular, marginal ridge nearly reaching the apex, 
disc feebly convex transversely with three vittz (one close 
to the suture) formed of minute granules each with a 
minute hair, a few scattered granules in the interspace 
next the margin, otherwise quite smooth. Prothorax be- 
neath punctate at middle, granular at the sides. Meso- 
and sides of metasternum coarsely granular. Abdomen 
moderately finely not closely punctate bearing short hairs. 
Legs roughly punctured. Length, .7o—.82 inch; 18-21 
mm. . 

This species has no closely related form in our fauna, 
although not very. different in outline from morzcordes of 
Mexico. It wi'l however be easily known by the feebly 
convex disc of elytra (rather less convex than in opaca) 
and by the replacement of the costz by rows of minute 
setigerous granules. 

Pescadero, west side. 


ASIDA DENSICOLLIS n. sp. Plate vii, fig. 5. 

Very like carinata or bifurca in general form, black, 
dull. Head densely punctured. Thorax trapezoidal, 
wider than long, widest one-third from apex, apex teebly 
emarginate, angles not prominent in front, sides arcuate 
in front, oblique behind, hind angles rectangular not 
prominent, disc rather strongly convex densely and rather 
roughly punctate, more roughened at ‘sides and base. 
Elytra oval, broader behind the middle, one-half longer 


418 CALIFORNIA ACADEMY OF SCIENCES. 


than wide, base as wide as the base of thorax, humeri 
oblique, marginal costa extending three-fourths to apex, 
disc convex with a well marked costa extending from 
base within the humerus more than two-thirds to apex, 
within this costa a much fainter one, nearly as long, 
slightly oblique to the suture, surface finely and moderately 
closely granulate. Prosternum coarsely closely punctate, 
propleure punctate-granulate. Mesosternum and meta- 
sternum granulate. Abdomen muricately punctate, more 
coarsely at the sides. Legs muricately punctate with short 
hains. Wenoth,..521nchs913) mm’. 

This species with the general outline and facies of 
carinata has the disc of the thorax convex and more 
roughly sculptured for its size than any species in our 
fauna. The inner costa of the elytral disc is very faint 
resembling a similar structure in acfwosa where the costa 
may be entirely absent. 

Two specimens. One in Mr. Wickham’s cabinet from 
N. Yakima, Wash., the other in my own labelled doubt- 
fully as from Oregon. 


ASIDA IMPETRATA n. sp. Plate vil, fig. 4. 

Form oblong resembling fara//ela, piceous or dark 
brown, dull. Head coarsely not closely punctate, occiput 
and neck densely punctate. Thorax at least one-half 
wider than long, widest slightly behind the middle, base 
not wider than apex, apex emarginate with angles prom- 
inent to the front, sides regularly arcuate, hind angles 
rectangular, disc feebly convex, the lateral margin slightly 
explanate and slightly reflexed, surface moderately 
coarsely, evenly, but not densely punctate, along the 
lateral margin very coarsely punctate, surface with ex- 
tremely short yellow hairs, the lateral edge similarly 
fimbriate. Elytra oblong, twice as long as wide, at base 


COLEOPTERA OF BAJA CALIFORNIA. 419 


narrower than the thorax, humeri very obliquely rounded, 
lateral marginal ridge reaching nearly to the apex, disc 
moderately convex and with three coste, the outer be- 
ginning at the lateral margin behind the humerus, extend- 
ing near to apex and sinuous near its end, the second 
costa does not quite reach the base, is slightly oblique to 
the suture and indistinctly joins the outer costa near 
apex, inner costa faint joining the next outer one fourth 
from apex, these coste and the lateral edge fimbriate at 
their summits with extremely short hairs, surface very 
finely and closely punctate. Pro-, meso- and metasterna 
coarsely not closely punctate. Abdomen rather closely 
and finely submuricately punctate with short yellow hairs. 
Legs roughly puuctate and slightly hairy. Length, 
.42-.56 inch; 10.5-I14 mm. 

This species must be placed near parallelus differing 
in its opaque surface, tricostate elytra and more narrowly 
reflexed sides of the thorax. 

San Diego and Yuma, California. This species will 
doubtless occur in Baja California. 


AsIDA EMBAPHIONIDES n. sp. Plate vii, fig. 8. 


Form rather slender and graceful, dull brown suture 
and two lines on each elytron faintly paler. Head 
coarsely and closely punctate. Thorax more than half 
wider than long, slightly narrower between the basal than 
the apical angles, apex deeply emarginate, base bisinuate, 
sides regularly arcuate, disc flat, the margin broad and 
widely reflexed, the edge slightly crenulate and with short 
hairs, surface sparsely punctate, each puncture with a 
short hair. Elytra less than twice as long as wide, widest 
at middle, humeri very oblique, lateral margin sharp and 
slightly reflexed, marginal line suddenly incurved one- 
fourth from apex, thence oblique nearly to apex, disc 
nearly flat transversely, surface with sparsely placed erect 


420 CALIFORNIA ACADEMY OF SCIENCES. 


spinules of peculiar structure. Prosternum sparsely 
punctate, with short erect hairs, propleurz more coarsely 
punctate. Abdomen sparsely finely punctate, with short 
erect spinules. Legs roughly punctured with short hairs. 
Length, -Go 1nch;’ 15*mm. 

This species is very peculiar in its form, having nothing 
in our fauna with which it may be compared. The widely 
reflexed thoracic margin, the flat and very acutely mar- 
gined elytra suggest vaguely Embaphion or some species 
of Akis. 

The spinules of the elvtra and abdomen are of very 
peculiar construction. When examined under the high- 
power hand lense they are seen to be really feathers or 
spines pectinate on two edges, as in the tibial spurs of 
Prionochaeta and some other genera. 

One specimen. San José del Cabo. 


AstpA WIcCKHAMI n. sp. Plate vii, fig. 7. 


Exactly of the form of parallela, dull brown opaque, 
thorax less opaque. Head sparsely punctate, slightly 
hairy. Thorax about a third wider than long, widest 
slightly in front of middle, not wider at base than apex, 
sides arcuate, apex moderately emarginate, base bisinu- 
ate, disc slightly convex, a finely impressed median line, 
lateral margin rather widely reflexed as in faradlela, sur- 
face sparsely punctate, each puncture with a short erect 
hair, the margin with short hairs. LElytra oval, broadest 
slightly behind the middle, humeri distinct but not prom- 
inent, marginal ridge extending nearly to apex, disc flat 
at middle, a sharply elevated costa arising within the 
humerus extends three-fourths to apex, a short costa 
branches from the marginal behind the middle and extends 
parallel with the inner costa, surface sparsely punctate, 
with short erect hairs. Prothorax beneath sparsely punc- 
tate. Abdomen finely not closely punctate, with short 


COLEOPTERA OF BAJA CALIFORNIA. 421 


erect hairs. Legs roughly punctured with short hairs. 
Length, .56 inch; 14 mm. 

This species so closely resembles pavral/ela that a spec- 
imen sent me by Mr. Wickham covered with the argilla- 
ceous coating so common in Asida was labeled farallela. 
It has exactly the same form and facies, but differs in its 
opaque surface and by the presence of a short additional 
costa branching from the marginal ridge. 


Riverside, Arizona. Collected by Mr. H. F. Wickham. 


AsIDA CONNIVENS Lec. A short time since, I stated 
that this species is the male of d¢fwrca. In the present 
series it is shown that the only character of those men- 
tioned by Le Conte for the separation of the two species 
of any value resides in the prominent hind angles. How- 
ever, in a somewhat related species, A. confluens, the 
hind angles of the thorax are similarly prominent in the 
male, and to that extent confirm the view expressed. 


A. HORRIDA Champion, Biol. Cent. Am., iv, Dts weeps 
500, pl. xxii, fig. 15, occurs in Texas near the lower Rio 
Grande, the Mexican locality being Nuevo Laredo, Tam- 
aulipas. It is probably best placed in our series near 
sexcostata. ‘The surface has short inconspicuous hairs, 
the side margin of thorax reflexed as in Avrsuta, each 
elytron with two feeble discal costa parallel with the suture. 


A. OBLITERATA Champion, soc. cis., p. 493. This 
occurs in southern Arizona. At first glance this species 
would be placed near marginata, but the disc of thorax 
is scarcely convex and the lateral margin not reflexed, 
nor is there the median basal impression. 


EUSATTUS SECUTUS n. sp. 


Very like Z. dudius, but a little more convex, oblong 
oval, black, moderately shining. Head opaque, sparsely 
punctate, clypeus nearly entire. Thorax rather more

sternum coarsely punctured between the coxe, the tip 
rounded and with a distinct marginal bead. Abdomen 
very sparsely and finely punctate, shining. Length, .37- 
.40 inch; 9-10 mm. 

This species could not be mistaken for any other, ex- 
cept duwbzus, from which it differs in its smooth surface, 
nearly entire clypeus and margined prosternum.

clypeus deeply and broadly emarginate with a moder- 
ately deep incisure each side, the entire margin of the 
front reflexed. Thorax more than twice as wide as long, 
much narrowed in front, sides arcuate, the margin ex- 
planate, hind angles slightly prolonged but not acutely, 
disc of thorax smooth with a few fine piliterous punctures 
near the side. Elytra without lateral margin, surface 
with minute sparsely placed submuricate granules each

ARGOPORIS EBENINA N. sp. 

Black, somewhat dull. Head moderately finely and 
closely punctate, clypeus truncate. Thorax a little wider 
than long, narrower at base than apex, sides moderately 
arcuate, slightly sinuate near the hind angles which are 
rectangular, disc slightly flattened posteriorly, surface 
very finely and moderately closely punctate. Elytra ob- 
long oval, widest slightly in front of middle, humeri 
slightly dentiform, disc slightly flattened, substriate with 
more distinct punctures in the male or with rows of fine 
punctures in the female, the seventh interval costiform at 
apex, joining an oblong tubercle on the first. Proster- 
num finely punctate, propleure granulate. Mesopleure 
cribrate, metapleura coarsely punctate. Abdomen finely 
punctate, wrinkled longitudinally. Legs black, finely 
sparsely punctate. Length, .55-.63 inch; 14-16 mm. 

Male. 


angle prolonged inward. Posterior femora with a long 


Anterior tibiz serrate within, the inner apical 


slender tooth one-third from apex. A tuberosity at mid- 
dle of first ventral segment. 

Female.—Anterior tibia very feebly serrate, the inner 
apical angle not prolonged. Posterior femora simple. 

This is the largest species in our fauna, differing from 
all by the velvety black color of surface and legs, and in 
the male it differs from all but the next species in the 
presence of but one tooth. 

The elytral sculpture of the male consists of fairly im- 
pressed striaz with moderate punctures not closely placed, 
intervals slightly convex, very finely sparsely punctulate. 
In the female there are no striz, simply lines of fine punc- 
tures, the intervals flat and minutely punctulate.

ARGOPORIS INCONSTANS DN. sp. 


Piceous black, rather dull, legs red. Head finely punc 
tate, clypeus truncate. Thorax a little wider than long, 
slightly narrowed at base, sides feebly arcuate, hind an- 
gles distinct, disc slightly flat, surface very finely sparsely 
punctulate, sometimes very indistinctly. Elytra oblong, 
widest at middle, humeri slightly prominent, surface va- 
riable in sculpture either subcostate as in costzpennis or 
quite smooth as in a/utacea. Prosternum beneath opaque, 
obsoletely punctate. Meso- and metapleure coarsely punc- 
tate. Abdomen finely punctate, longitudinally wrinkled. 
Length, .45-.53 inch; 1I1.5-13.5 mm. 

Varzations.—The extreme form has the elytra striate 
with moderately coarse punctures, intervals convex and 
near apex costiform. This form is known from San 
Diego and San Esteban. 

The other extreme has the ordinary series of striate 
punctures, the intervals flat, not costiform at apex. San

from a/utacea—but in these latter the clypeus is always 
arcuate and not truncate.

CERENOPUS ANGUSTATUS n. sp. Plate vii, fig. 9, head. 


Piceous black, rather dull, form slender. Head sparsely 
punctate, more evident in the male, clypeus emarginate 
at middle. Thorax as broad as long, widest slightly in 
front of middle, sides regularly arcuate with a slight 
sinuation posteriorly, disc regularly convex, almost ab- 
solutely smooth along the middle becoming gradually 
more distinctly punctate toward the sides. Elytra oblong, 
rather acute posteriorly, humeri prominent, disc with 
rows of coarse punctures which are large, shallow and 
vague in the male, sharply impressed in the female, the 
intervals vaguely convex, slightly costiform near apex. 
Prosternum opaque with transverse wrinkles and few

coarse punctures or granules, the pleure sparsely granu- 
late. Meso- and metapleure granulate. Legs sparsely 
punctulate, the tibize rougher at apical half. Length, .65 
inch; 16.5 mm. 

Male.—Anterior tibie serrate within, the inner apical 
angle prolonged, anterior femora very abruptly narrowed 
at base. Posterior femora with a moderately long, slen- 
der tooth one-third from apex. 

Female.—Anterior tibiz not serrate within the inner 
apical angle prolonged, the femur not abruptly narrowed 
at base; posterior femora simple. 

In the male the first three ventral segments are slightly 
concave and smooth, the sides of the segments granulate- 
punctate. The female has the first three segments coarsely 
punctate from side to side, at middle slightly flattened. 

In both sexes the last two ventrals are finely punctate. 

The elytral sculpture of this species is of the same 
type as seen in concolor and shows a tendency to vary as 
in Argoporis tnconstans. 

Two specimens. San José del Cabo. 


DoLIOPINES nov. gen. 


Form oblong, parallel, depressed, body alate. Head 
dissimilar in the sexes, transverse male, oval female, the 
clypeal margin truncate male, arcuate female. Eyes 
transversely oval, coarsely granulate, deeply emarginate 
by the sides of the clypeus. Labrum transverse, feebly 
trilobed in front. Mandibles slightly visible beyond 
the labrum, apex bidentate. Mentum hexagonal with 
rounded angles, emarginate in front, partly membranous 
anteriorly. Ligula membranous, lanceolate. Labial palpi 
moderate in length last joint cylindrical as long as the 
two preceding joints, membranous at tip. Maxillary palpi 
longer, the second and fourth joints equal, third shorter, 
fourth joint slightly broader to tip, obliquely truncate, tip 


428 CALIFORNIA ACADEMY OF SCIENCES.: 


membranous. Antenne arising under the sides of clypeus 
in front of the eye, more slender and two-thirds the 
length of body in male, shorter and more robust in the 
female; first joint conical, second small, third as long 
(female) or a little longer (male) than the first, joints 
4-11 equal in length, slightly flattened, each two-thirds 
as long as the third joint. Thorax broader than long. 
Scutellum small, triangular. Elytra without explanate 
margin, epipleure terminating abruptly near the apex. 
Prosternum not wide between the coxe, coxal cavities 
round not angulate externally. Middle coxal cavities 
slightly open externally with a feeble trochantin. In- 
tercoxal process of abdomen acutely triangular. An- 
terior tarsi with joints 1-4 small, together scarcely longer 
than the fifth, middle tarsi first joint as long as next two, 
hind tarsi first joint longer than next two and as long as 
the fourth. Vestiture of tarsi consists of stiff hairs. Ab- 
domen as in Doliema. 

In the above description as many details are given as 
possible that the close relationship with Doliema may be 
realized. The only valid difference is in the form of the 
head, that of Doliema having the sides of the clypeus 
prolonged anteriorly in the male and with a distinct sinua- 
tion in the female, while in the present genus the clypeus 
is arcuate in both sexes more obtuse at middle in the 
male.

a little less than twice as wide as long, slightly narrower 
in front of the female, sides feebly arcuate, the angles 
obtuse, base slightly arcuate with a marginal line, disc 
freely not closely punctate, a faint basal impression each 
side of middle. Elytra very little wider than the thorax,

NOTIBIUS REFLEXUS n. Sp. 


Form nearly of JV. ofacus, velvety black. Head mod- 
erately closely punctate, finer on the clypeus, the latter 
moderately deeply emarginate. Thorax broader than 
long, widest a little in front of middle, base slightly nar- 
rower than apex, sides arcuate, hind angles rectangular. 
Elytra slightly oblong or regularly oval, wider than the 
thorax, the entire lateral margin visible from above and 
slightly reflexed near the humeri, disc convex, very finely 
striate, striz finely and closely punctate, intervals flat, 
slightly convex near the apex, very finely punctulate. 
Prosternum punctate-granulate, propleure strigose. Meso- 
and metasternum coarsely punctate. Abdomen finely 
punctate. Legs black, finely submuricately punctate. 
Length, .15-.20 inch; 4-5 mm. 

The anterior tibia are merely slightly broader from 
base to apex and similar in the two sexes. The male 
has the first two ventral segments slightly flatter at mid- 
dle. 

This is the only species known to me in which the 
entire lateral margin of the elytra is visible from above 
and slightly reflexed near the base. 

Occurs at San José del Cabo.

NoTIBIUS COSTIPENNIS n. Sp- 


Similar in form to JV. ofacus, black, opaque. Head 
roughly punctured between the eyes, clypeus smoother, 
broadly emarginate. Thorax broader than long, widest 
in front of middle, sides arcuate, hind angles distinct, 
disc moderately convex, punctuation dense and some- 
what strigose longitudinally, surface very opaque. Ely- 
tra a little wider than the prothorax, disc convex, deeply 
sulcate, with a row of coarse ill-defined punctures, inter- 
vals acutely costiform. Prosternum coarsely not deeply 
punctured, propleure longitudinally strigose. Metaster- 
num at sides coarsely punctate. Abdomen sparsely 
punctate and more shining. Legs black, alutaceous, 
not closely submuricately punctate. Length, .22 inch; 
Seis aavaol 

Of this species I have seen but two somewhat mutilated 
specimens, which show no evidence of sexual difference. 
It resembles saw/catus, but differs from that in having the 
thorax distinctly narrower behind, as in ofacus, and by 
the acute elytral intervals. 

Magdalena Island and Lower Purisima. 

Notibius is used in the same sense as in the Class. Col. 
N.A. or my Revision of the Tenebrionidz. Inthe Proc. 
N. Y. Acad. Sciences, v; 1890, Capt. Casey has modi- 
fied the definition of Conibius and Notibius in such a 
manner as to cause a rather heterogeneus distribution of 
the species and requiring the formation of the genus Con- 
ibiosoma, which is certainly untenable. 


HELOPS PINGUIS N. sp. 

Form nearly intermediate between farctus and @reus, 
castaneous brown (slightly immature? ), the surface faintly 
bronzed. Antenne slender, two-thirds the length of 
body, joints 4-7 and 8-11 equal in length, the last series 


COLEOPTERA OF BAJA CALIFORNIA. 431 


distinctly longer than the first. Front flat or slightly con- 
cave, moderately coarsely and closely punctate. Thorax 
nearly twice as wide as long, widest at middle, apex 
truncate, angles not prominent, sides arcuate, the margin 
acute, base truncate with obtuse angles, disc moderately 
convex, a crescentic depression near the base, moder- 
ately coarsely and closely punctate. Elytra oval, slightly 
prolonged at apex, convex, moderately deeply striate, 
striz coarsely not closely punctate near base, gradually 
more finely toward apex where the punctures disappear, 
intervals convex, smooth. Prothorax beneath at middle 
and sides more coarsely punctured than above. Meso- 
and metasternum less coarsely punctured. Abdomen 
more sparsely and gradually more finely punctate toward 
the apex. Body apterous. Length, .26 inch; 6.5 mm. 

The form of this species is more nearly that of @reus, 
although more robust, while the rather deeply striate 
elytra suggest farctus. 

The name Helops is used in the sense intended by 
Lacordaire. The numerous genera into which it has 
been divided are not only difficult of appreciation, but so 
indefinite that disagreement with the position of species 
is expressed by about every one who has followed Allard. 

One specimen. Coral de Piedra, Sierra El Taste. 


PHEDIUS OPACULUS nN. sp. 


Dull black, opaque, form very like carbonarius. An- 
tennez black or brownish. Head punctate, not coarsely, 
somewhat more closely in the male. Thorax one-fourth 
wider than long, slightly narrower at apex than base, 
sides feebly arcuate, base feebly arcuate, hind angles 
obtuse, disc convex, sparsely punctate. Elytra oval, 
convex, slightly wider at base than the thorax, disc with 
striz of faint punctures sometimes nearly obliterated, in-

tervals flat, not punctate, the surface microscopically 
alutaceous. Body beneath very sparsely punctate. Ab- 
domen smooth. Legs finely sparsely punctate. Length, 
.36-.40 inch; 9-10 mm. 

At first sight this insect would be thought a Helops 
allied to dificelis or spretus. ‘The figure given by Mr. 
Champion (Biols, iv, pt. 1, pls xx;-ie 19) very closely 
resembles our species, excepting the pilose surface of 
carbonarius. It is, however, more closely related to 
hidalgoensis, which, however, has the interstices finely 
and sparsely punctured. 

Sierra Laguna, El Taste and Pescadero. 


ALLECULA SORDIDA “i. sp. 


Brownish black, dull, sparsely clothed with short black 
erect hair. Head coarsely and moderately closely punc- 
tate. Thorax about one-fourth wider than long, narrower 
in front, sides arcuate in front then parallel to base, hind 
angles rather obtuse, disc convex, a slight median im- 
pression near the base, basal fovea small, surface densely 
and moderately coarsely punctate. Elytra with striz of 
moderate size, closely placed punctures, the stria slightly 
impressed near the apex, intervals flat punctate, punctures 
as large as of the striz, but gradually finer to apex. 
Prothorax more sparsely punctured beneath than above, 
sides of meso- and metasternum more coarsely punctured. 
Abdomen finely sparsely punctate. Body beneath with 
short yellow hairs. Legs closely punctate. Length, 
401ineh; LO mam. 

This species resembles the figure of rugzcollis Ch. 
(Biol., iv, pt. 1, pl. xviii, fig. 17), and from descmption 
seems most closely related to pz/7pes Ch.

LysTRONYCHUS CHAMPIONI nN. sp. 


Entirely black, sub-opaque. Head densely and rela- 
tively coarsely punctured. Thorax more than half wider 
than long, sides strongly arcuate from the front angles to 
middle where there are two distinct teeth, thence narrow- 
ing to base, disc regularly convex, very densely punc- 
tured. Elytra broader than the thorax, slightly wider 
behind the middle, disc with striz of very closely placed 
punctures, the intervals flat with a single row of punc- 
tures, some of which are much larger and bear a short, 
erect, stiff black hair, submarginal stria quite deeply im- 
pressed. Prosternum coarsely sparsely punctate, the 
pleurze densely punctate. Meso-metasternum coarsely 
punctate. Abdomen shining much more finely and 
sparsely punctate. Legs black, punctate. Length, .28 
inch; 7mm. 

A slightly larger and more convex species than scapu- 
lar?s with less opaque surface, which has a faint bluish 
tinge. The humeral red spot in the Mexican species 
being a constant character affords an additional means of 
distinction. The above described species with scapularts 
and denticoll7s agree in having the sides of the thorax bi- 
dentate. 

I dedicate the species to Mr. Champion, who has given 
us in his treatment of the genera of Mexico the correct 
elements for proper classification of the family. 

One female, western Texas. 

The two species now known in our fauna are as follows: 


Antenne slender, outer joints not flattened; thorax scarcely wider than 
long, the sides not dentate. piliferus. 

Antenne broader externally, the joints subserrate; thorax broader than 
long, sides bidentate at middle. Championi. 


Both species occur in Texas, the former extending as 
far as Brazil.

HYMENORUS PLANULUS 0. sp. 


Oblong, parallel, similar in form to occzdentalis but 
much more depressed, piceous, semi-opaque, antennz 
and legs ferruginous. Antenne not longer than half the 
body, third joint longer than fourth. Head coarsely not 
closely punctate, clypeus more densely, eyes large, nar- 
rowly separated. Thorax one-half wider than long, sides 
arcuate in front nearly parallel in basal half, hind angles 
sharply rectangular, disc slightly convex, coarsely densely 
punctured (as in occrdentalis ). Scutellum densely punc- 
tured. Elytra a little wider than the thorax, sides nearly 
parallel, gradually narrowing at apical third, the sutural 
angle obtuse, disc flat finely striate, striz closely finely 
punctate, intervals flat, moderately closely punctate and 
with short brown hair. Prosternum densely punctate, 
propleurz quite smooth near the margin. Abdomen shin- 
ing, sparsely finely punctate. First joint of hind tarsus 
longer than the following joints. Length, .30 inch; 7.5 
mm. 

One female specimen evidently related to occ¢dentalzs 
from the table given by Capt. Casey (Ann. N.Y. Acad., 
1891, p. 86), but differing in smaller size, much more de- 
pressed form, darker color and less pubescent surface.

HYMENORUS SPINIFER 0. Sp. 

Oblong, sub-depressed, piceous, slightly shining, 
sparsely clothed with short brownish hair, form very like 
occidentalis, but more depressed. Antenne about half 
the length of the body, ferruginous or piceous, third joint 
in both sexes very little longer than the fourth. Eyes 
large, narrowly separated, head coarsely punctured be- 
tween them. Outer side of last joint of maxillary palpus 
longer than the apical side. Thorax about a third wider 
than long, sides convergent nearly from the base, more 


COLEOPTERA OF BAJA CALIFORNIA. 435 


arcuate anteriorly, hind angles rectangular, disc moder- 
ately convex, coarsely and closely punctate. Elytra 
more than twice as long as wide, sides parallel, arcuately 

narrowing at apical third, the apex slightly sinuate near 
the suture, the sutural angle prolonged into a spine, disc 
slightly flattened, finely striate, striae finely punctured, 
intervals flat, submuricately punctulate, but not densely. 
Prothorax beneath densely punctured and opaque, the 
propleure near the margin much smoother. Abdomen 
shining, sparsely finely punctate. First joint of hind 
tarsus longer than the following joints. Length, .37—.48 
inch; 9.5—12 mm. 

This species is described with the view of introducing 
an element in Hymenorus hitherto unrecorded—the spin- 
iform prolongation of the sutural angle. I have, in addi- 
tion, a second species closely resembling occ¢dentalis 
superficially, with the sutural angle acute, but never with 
the spine so well developed as in spinifer. ‘The species 
now described is related to occ/dental’s and is the largest 
species known in the genus. 

Mr. Champion has recorded the spiniform suture in 
several species of Lobopoda, and, from the yet unstudied 
material in my cabinet, the line of demarcation between 
that genus and Hymenorus is becoming gradually effaced. 

Four specimens. Southern Arizona. 


SISENES CHAMPIONI n. sp. 


Elongate, nearly parallel male, broader behind female, 
head and thorax black shining, witha slight tinge of blue, 
elytra entirely orange-yellow with similar pubescence. 
Antenne black, slender in both sexes, third joint shorter 
than the fourth. Head elongate, sparsely, finely and in- 
distinctly punctate. Thorax one-fourth longer than wide, 
widest one-third from apex, sides anteriorly slightly arcu- 
ate, posteriorly feebly sinuate, disc feebly convex a vague

triangular flattening from the apex toward base, finely, 
sparsely punctate a broad vitta of fulvous hairs each side, 
black along the middle. Scutellum black. Elytra nearly 
twice as wide as the base of the thorax, disc faintly tri- 
costate, one costa on the deflexed sides the other two su- - 
perior within the humerus, surface densely finely punc- 
tate, clothed with short fulvous hairs. Body beneath and 
legs deep blue-black, shining. Abdomen sparsely punc- 
tate. Length, .36-.40 inch; 9-10 mm. 

The male has the last ventral segment deeply emargi- 
nate, in the female it is simply truncate. This species 
belongs to Champion’s group 1—a characterized by filiform 
antenna in both sexes, and with the first four joints of 
the front and middle tarsi and the third of the hind tarsi 
tomentose beneath. 

From the figures given by Mr. Champion of many of 
his species there is no indication of as elongate a head as 
the present species. In fact, the head is nearly as elon- 
gate as in Rhinoplatia. 

Collected in southern Arizona (Morrison). 


MACROBASIS TENUILINEATA Nn. sp. 


Elongate, castaneo-testaceous, moderately densely 
clothed with grayish white pubescence forming three 
slender more distinct lines on the disc of each elytron 
and one less distinct at the sides. “Antenne slender, 
black. Head densely punctured. Thorax longer than 
wide, sides convergent in front, parallel behind the mid- 
dle, surface densely punctured, a finely impressed me- 
dian line. Elytra parallel densely punctured, cinereo- 
pubescent distinctly denser in three lines on the disc of 
each. Body beneath densely punctured and pubescent, 
the apical margin of each ventral segment piceous. Legs 
concolorous the knees piceous. Length, .40—-.55 inch;

Male.—First joint of antenne not difformed, shorter 
than second, this somewhat thickened and nearly as long 
as the next three. Anterior tibiz with two spurs. 

Fremale.—Second joint of antenne not thickened and 
not longer than the first. 

The first two joints of the female antennz are conspic- 
uously cinereo-pubescent, in the male nearly glabrous. 
In all the females before me there is a piceous spot each 
side of the scutellum and in front of the humeral umbone, 
not seen in the male. 

This species may be associated with éenw7s and uwnicolor 
in the arrangement suggested by me some years ago

CALOSPASTA DECOLORATA DN. sp. 

Form rather short, deep violet, the elytra entirely red- 
dish-yellow (male), or with an oval piceous spot on the 
middle of suture. Antennz short, compact. Head 
broadly oval, occiput truncate, surface coarsely irregu- 
larly punctate. Thorax quadrate, broader than long, nar- 
rowed for a short distance in front, disc feebly convex 
without median impressed line, surface nearly smooth 
with very indistinct scattered punctures (male), or with 
coarse irregularly placed punctures (female). Elytra 
much wider at base than the thorax sides parallel (male), 
or slightly divergent (female), surface coarsely scabrous 
with two feeble costa on the disc near the suture. Body 
beneath deep blue, sparsely silken pubescent. Legs blue, 
sparsely hairy. Length, .30-.36 inch; 7.5-9g mm. 

In the male the last ventral segment has a small acute 
notch, in the female truncate. The upper surface from 
indications is sparsely clothed with short silken pubes- 
cence. The spurs of all the tibiz are slender and sim- 
ilar.

From its broad thorax and other characters this species 
should be placed near Fu//er7, from which it differs rad- 
ically in color. 

Calmalli Mines. 

It is highly probable that Mr. Champion has realized 
the extremely close relationship existing between Calos- 
pasta, Tegrodera and Eupompha, and but few more spe- 
cies are needed to unite the three beyond question. Re- 
cently (Ann. N. Y. Acad., 1891, p. 175) Capt. Casey has 
described the genus Negalius, which does not show any 
structural differences from Calospasta, the grooved man- 
dibles and dilated tarsi occurring in the latter genus. 

The most remarkable discovery, however, is the result 
of the collections of Mr. D. W. Coquillett of Los Angeles. 
During a visit to him in May, 1893, he gave me what I 
recognized as a Calospasta. The male has the form of 
Fullert (which is rather that of a Tetraonyx than a Ca- 
lospasta), but the female is from any standpoint of class- 
ification a Meloide, apterous and with the meso -coxe 
overlapping the metasternum. In fact, the female was 
described by me many years ago as J/egetra opaca. 

Megetra opaca, or Calospasta opaca, as it must now be 
called, is somewhat variable. I have three series of spec- 
imens, the first represented by six taken by Mr. Gabb 
near Los Angeles about thirty years ago; a second series 
of eleven from Morrison, taken about ten or twelve years 
ago, with no special locality other than southern Califor- 
nia; a third series from Mr. Coquillett, taken near Los 
Angeles in 1893. The first two series are all females. 
In the last series three are males and four females. 

The last series has the elytra coarsely punctate sca- 
brous, the first series the elytra are less coarsely punctate 
and less coarsely scabrous, while the Morrison series is 
comparatively smooth. These subdivisions are not sharply 
drawn, but describe the general aspect of each series. 


COLEOPTERA OF BAJA CALIFORNIA. 439 


As opaca must now be placed in Calospasta, it can be 
separated from /w//erz in the following manner: 
Thorax moderately shining with scattered coarse punctures; elytra entirely 

covering the body in both sexes which are winged. Fulleri. 
Thorax opaque comparatively smooth and impunctate; elytra covering the 

body in the male, body winged, elytra much abbreviated and diver- 

gent from the seutellum, body opterous in the female. opaca. 

From the study thus briefly made the further conclu- 
sion suggests itself that the tribe Meloini, based as it is 
on apterous forms and the consequently short metaster- 
num, is unnatural, and that the genera composing it 
should form part of other tribes. Thus Meloe would as- 
sociate with Cantharis, Henous with Epicauta, the two 
species of Nomaspis divide—one toward Cantharis, the 
other to Epicauta. Megetra and Poreospasta ally with 
Calospasta, Tegrodera et al. Cysteodemus seems un- 
related. We have already in Hornia an apterous Sitaride, 
although Mr. Champion has allowed himself to be misled 
by the prevailing methods of classification, and has formed 
for it a tribe apart. 


PyROTA TROCHANTERICA N. sp. 


Elongate, black, feebly shining, head and thorax in 
part yellow, elytra with the suture, margin and apex nar- 
rowly yellow and an arcuately oblique yellow vitta each 
side of the scutellum. Antenne black, slender, setace- 
ous. Head elongate oval, very sparsely punctate, occi- 
put black, front yellow with a central piceous spot and 
four smaller ones anteriorly in an arcuate row. Labrum 
black, coarsely punctate. Thorax much longer than 
wide, sides parallel behind, obliquely narrowing in front, 
disc rather flat, smooth, a few punctures at the sides, 
color in great part black, in front yellow to a variable ex- 
tent. Scutellum black. Elytra moderately closely punc- 


tulate and vaguely tricostate. Body beneath black.

440 CALIFORNIA ACADEMY OF SCIENCES. 


Trochanters conspicuously yellow. Legs black, the ba- 
sal half of the middle and hind tibiz yellow. Length, 
.36-.64 inch; 9-16 mm. 

Male.—Last joint of maxillary palpus transverse, nar- 
rowly oval, inner angle acute, the under side concave. 
Fifth ventral segment triangularly impressed at apex, 
sixth deeply and broadly emarginate. 

Female. — Last joint of palpus cylindrical, slightly 
broader at middle, apex truncate. Last ventral segment 
with a small triangular notch. 

This species resembles zzsez/ata Lec., but the elytra 
have not the apical yellow spot. The legs, including the 
trochanters, are entirely black in zmsu/ata. The elytral 
coloration resembles the figure of d7v7rgata var. (Biol., 
iv, pt. 1, pl. 21, fig. 17), but the color of the trochaniers 
is not noticed in the descriptions, and if conspicuously 
pale, as in ¢rochantericus, would certainly have been.

near the base and within each hind angle, surface closely 
punctate. Scutellum rufous. Elytra densely punctate, 
extremely finely bicostate. Body beneath rufescent, more

num tipped with black. Ventral segments with a trans- 
versely oval spot on each side. Legs rufous, knees, tips

EPIC4RUS LUCANUS n. Sp. 


Pyriform, moderately robust, elytra densely clothed 
with cinereous and ochreous scales forming an illy de- 
fined pattern of three oblique fascia on each side, the 
inflexed portion of sides much whiter. Rostrum quad- 
rangular, parallel, flat above, a fine median groove end- 
ing ina fove between the eyes, lateral sulci wanting or 
indicated by a vague fovea, surface above coarsely sparsely 
punctate and sparsely scaly, beneath densely scaly. Tho- 
rax conical with slightly arcuate sides, the base a fourth 
wider than long, disc convex, the median line with a fine 
groove interrupted at middle, surface with coarse scat- 
tered punctures, the interspaces finely punctate, scaly 
vestiture not dense; under side of prothorax very densely 
scaly. Elytra regularly oval, not compressed at apex, 
with striz of coarse deep punctures, intervals (when 
abraded) very finely punctulate, scaly vestiture dense 
with very short erect hairs irregularly placed. Body be- 
neath very densely scaly. Middle and posterior femora 
conspicuously more densely scaly at apex. Length 
(apex of thorax to tip of elytra), .32-.58 inch; 8+1r4.5

This species is given a name not without some misgiv- 
ings that it may be one of the forms described from Mex- 
ico, but the descriptions of some of the more recently 
described species from that region are annoyingly short 
and unsatisfactory. As compared with our Boreal Amer- 
ican species it is far more robust than ¢mdricatus, approach-

RHIGOPSIS SIMPLEX Nn. Sp- 


General form of /. efracta and recalling the facies of 
some macrops, clothed with dirty white, broadly oval 
thin scales, the middle and sides of thorax darker and 
with series of darker spots on the elytra. Beak with fine 
median sulcus extending from apex to occiput, lateral 
sulci scarcely evident. Thorax broader than long, widest 
near apex sides straight and slightly convergent behind, 
a slight post-apical constriction, disc very coarsely and 
deeply punctured, a vague median depression. Elytra 
regularly oval, disc convex the suture and two discal 
coste feebly elevated without tuberosities, the intervals 
with striz of coarse punctures almost entirely concealed 
by the broad leaf-like scales. Body beneath with brown- 
ish-white scales. Length, .18 inch; 4.5 mm. 

As in effracta the surface has short, semi-erect curved 
hairs, sometimes concealed by the surface exudation. 
This species may be known from efracta by the absence 
of tuberosities, the feeble elytral costa and the almost 
entire absence of lateral rostral sulci. 

Calmalli Mines. 

An examination of my series of /. ef/racta shows that 
Pe. scutellata Cas. (Ann. N. Y. Acad., 1888, p. 242) can- 
not be retained as distinct, the species having doubtless 
been described from females. The scutellar character 
has no value, as several of my specimens have the scutel- 
lum entirely concealed by the elevations near it. 


GEODERCODES HISPIDUS Nn. sp- 


Oblong, piceous, densely dotted with brownish scales 
with paler scales intermixed on the disc, at sides the 


COLEOPTERA OF BAJA CALIFORNIA. 443 


whiter scales predominant and with moderately long and 
slender cinereous hairs over the entire surface. Head 
very sparsely coarsely punctate. Thorax nearly a half 
wider than long, broadest at middle, sides regularly arcu- 
ate, a feeble post-apical constriction, surface very indis- 
tinctly coarsely punctate. Elytra oval, the sides parallel 
for a short distance, humeri rounded, disc finely punctato- 
striate, intervals flat, irregularly biseriately punctate, each 
puncture with an erect hair. Body beneath with paler, 
less dense scales and with shorter hairs. Legs moder- 
ately densely scaly and with long hairs. Length, .20 
inch; 5 mm. 

I place this very inconspicuous insect in Geodercodes, 
from the fact that the second ventral segment is longer 
than the next two and the front tibiz are not serrulate 
within. It has the general form of Geoderces but less 
robust. The moderately long hairs is a character uni- 
versal in this part of the Otiorhynchide series. 

One specimen. San Jorge. 


THRICOLEPIS? SEMINUDA DN. sp. 


Form elongate, resembling in facies a diminutive Per- 
ataxia rugicollis, sparsely clothed with easily removable 
scales and with an irregular row of short whitish hairs on 
each interval. Beak longer than the head, longitudinally 
plicate, eyes surrounded by a groove, scrobes terminal, 
vague. Scape of antennz passing slightly the apex of 
thorax, shorter than the funiculus, the first two joints of 
which are moderately long and equal. ‘Thorax wider 
than long, sides regularly arcuate, a feeble post-apical 
constriction, disc convex, coarsely deeply and closely 
punctate. Elytra oblong-oval, nearly twice as long as 
wide, with regular rows of moderately coarse and closely 
placed punctures, the intervals flat and more than twice 
as wide as the striae, the scales narrow, semi-erect and 


444 CALIFORNIA ACADEMY OF SCIENCES. 


deciduous. Abdomen sparsely punctate, the first seg- 
ment transversely wrinkled. Legs paler, sparsely hairy. 
Length, .161nch; 4:mm. 

This species may be compared in facies to a small Per- 
wtaxia rugicollis, and almost equally to an elongate Aw- 
omias pellucidus. I place it in Thricolepis temporarily 
to avoid the necessity of erecting a genus for each new 
species. Unfortunately, the Le Conte system of classi- 
fication of the Curculionide, as a whole, is so radically 
different from that of Lacordaire that it 1s impossible to 
correlate the genera, especially of the Otiorhynchide, 
without actual comparison; and the more genera estab- 
lished on unique species and specimens, the greater will 
be the confusion in the future. 

Two specimens. San Julio. 


SCYTHROPUS DELICATULUS nN. sp. 

Form rather slender, densely clothed with pale green, 
oval, pearly scales. Antenne pale testaceous. Head 
with few short erect hairs, especially on the beak. 
Thorax very little wider than long, sides very feebly 
arcuate. Elytra widest behind the middle, disc finely 
striate, the punctures closely placed, intervals slightly 
convex. Body beneath less densely scaly, the scales 
more metallic. Legs*pale honey yellow. | Wength)\ or

A small, delicate species, with a facies of some of the 
European Phyllobius.

MirrosTvLUS “GRACIEIS Q.-sp- 


Form rather slender, densely clothed with ashy white 
rounded scales, elytra often maculate or banded with 
black. Antenne pale brown. Head with numerous 
elongate scales intermixed. Thorax variable, from longer 


COLEOPTERA OF BAJA CALIFORNIA. 445 


than wide to slightly wider than long, slightly wider at 
base than apex, sides feebly arcuate. Elytra oblong-oval, 
nearly twice as long as wide, base equaling the base of 
the thorax, disc finely striate, striae finely closely punc- 
tate, intervals feebly convex. Body beneath less densely 
clothed than above. Legsscaly. Length, .14—.19 inch; 
3.5-4.75 mm. 

This species varies to such an extent that with a few 
selected specimens it might be divided into three species. 
The first variety has on each elytron behind the base an 
oval brown-black spot variable in size, at the declivity a 
crescentic fascia of similar color, and near the apex an 
oval spot. 

In this form the cinereous scales of the surface have 
numerous brown ones intermixed. 

In the second form the sub-basal spots are small, the 
crescentic fascia is reduced to a small spot on each side 
and the apical spot is minute. 

The third variety has the spots so small that they might 
be mistaken for accidental abrasions. 

Specimens are before me with the post-basal spots alone 
present, others again with these absent and the two pos- 
terior spots present and very small.

POLYDROSUS PENINSULARIS DN. Sp. 


Form nearly of dorsalzs, clothed with cinereous scales, 
the elytra with a sinuous fascia of darker color at the 
declivity, variable -in width and color. Antenne pale, 
the club darker, scape joint longer than the hind margin 
of the eye. Head with some blackish scales. Thorax 
‘not longer than wide, slightly narrower in front, sides 
very feebly arcuate, disc covered with intermixed darker 


446 CALIFORNIA ACADEMY OF SCIENCES. 


scales. Scutellum longer than wide. Elytra much wider 
at base than the base of the thorax, a little wider behind 
the middle, humeri moderately prominent, disc convex, 
with fine stria, stria not densely punctured, intervals flat, 
with a row of extremely short sete. Body beneath scaly 
as above. Legs pale brown, with scales and hairs. 
Femora not dentate, tibia not sulcate. Length, .o8—.12 
inch; 2-3 mm. 

The specimens examined vary in the distinctness of 
the sinuous elytral band, in one specimen scarcely dis- 
cernible. 

This species is a true Polydrosus, and from the struc- 
ture of the antenne and their scrobes is related to the 
European ¢ereticollis. 

With Polydrosus the genus Cyphomimus is synony- 
mous, as indicated by Bedel (Coleop. du Bassin de la 
Seine, vi, p. 57, note). The species described by me as 
C’. dorsalis is probably the same as Polydrosus americanus 
Gyll.

CoOPTURUS QUADRIDENS ND. sp. 


Form moderately robust, densely clothed with white 
scales ornamented with brown. Front narrow, with in- 
termixed white and brown scales extending on the beak. 
Thorax as wide as long, constricted at apex, the angles 
prominent, limiting the constriction behind is an arcuate 
row of six tubercles, a tubercle at the middle of the apical 
margin, two tubercles on the disc behind the two middle 
tubercles of the arcuate series, sides of thorax irregular, 
median line carinate, surface with white scales with a 
transverse brownish space at base and the tips of the dis- 
cal tubercles. Elytra each prolonged in a_ truncate 
tubercle, a post-basal transverse ridge, on each elytron at 


COLEOPTERA OF BAJA CALIFORNIA. 447 


middle an arcuate row of four tubercles on each, convex 
anteriorly, tipped with fuscous scales, a tubercle on each 
elytron before the apex, surface with strie of coarse 
punctures almost entirely concealed by the scales, vestiture 
of white and brown scales intermixed. Body beneath uni- 
formly clothed with dirty white scales, the legs with in- 
termixed scales. Femora not toothed. Second ventral 
segment quadrituberculate along its posterior border. 
Léneth, 14 inch; 3.5, mm. 

Among the species at present known in our fauna this 
one is related to mammzllatus, but it differs strikingly 
from all by the pronounced tuberosities of the thorax 
and elytra. 

One specimen. El] Taste. 


BARIS PENINSULZ Nn. sp. 


Oblong-oval, form and general appearance of swbenea, 
black, shining, a slight eneous surface lustre. Beak 
stout, closely and relatively coarsely punctate, head 
almost smooth. ‘Thorax as wide at base as long, slightly 
narrowed in front, disc convex, coarsely and closely 
punctate with an incomplete,smooth median line, each 
puncture with a narrow white scale. Elytra slightly nar- 
rowed behind, about one-fourth longer than the thorax, 
deeply striate, intervals flat, the third a little wider and 
contusedly biseriately punctate, the other intervals irreg- 
ularly uniseriately punctate, each puncture with an 
elongate white scale. Pygidium coarsely and densely 
punctured. Body beneath coarsely and closely punctate, 
less so on the abdomen, each puncture with an elongate 
white scale. Prosternum not as wide between the coxe 
as the width of one of the coxe. Tibizx straight, without 
external dentiform process. Length, .15 inch; 4 mm., 
nearly. 


448 CALIFORNIA ACADEMY OF SCIENCES. 


Of this species four specimens have been examined. 
It seems to be related to aprzca Casey. The genus Baris, 
as accepted by Le Conte, has been subdivided by Capt. 
Casey, one of the important characters being the separa- 
tion of the anterior coxe, whether narrowly or widely. I 
have not been able to realize the importance of this char- 
acter, as the transition is so gradual that the position of a 
species becomes purely opinionative and controlled by 
facies.

NOTES ON CROTALUS MITCHELLII AND “ CROTA- 
LUS PYRREUS:” 


BY JOHN VAN DENBURGH. 


Among many interesting reptiles in the collection of 
the California Academy of Sciences are ten specimens of 
Crotalus mitchelliz, which throw much light upon the var* 
iation and distribution of this little-known species. 

Crotalus mitchell? was first described by Professor 
Cope (Proc. Acad.,-Phil., 1861, p. 263)), tromimea ‘singele 
specimen collected by Mr. John Xantus at Cape St. Lucas, 
Lower California. Mr. L. Belding secured another in- 
dividual at La Paz in 1882. These seem to be the only 
specimens of this species which have reached herpetolo- 
gists, from this region. 

Five years later (1. c. 1866, pp. 308 and 310) Professor 
Cope described a rattlesnake, obtained by Dr. Elliott 
Coues near Fort Whipple, Arizona, under the name of 
Caudisona pyrrha. 

C. pyrrhus was stated to differ from C. mztchellii— 

tst, by being ‘‘salmon red (pale vermillion)’’ instead 
of ‘‘ greyish yellow ”’ ; 

2d, by having four loreals instead of one; 

3d, two very small instead of two elongated preoculars ; 

4th, rattle subacuminate instead of parallelogramatic ; 

5th, fourteen instead of sixteen labials; 

6th, two rows of smooth lateral scales on each side in- 
stead of one. 

Dr. Stejneger, in a‘ very interesting paper i jue 
‘oWest American Scientist-’ for April 1601, statesean 
C. pyrrhus: ‘*None of the specimens obtained since 
(the type) show a similar coloring. * * * In all (five) 
of them the ground color is a slightly buffy white, more 
or less sprinkled with black dots, giving it a kind of 


2p SER., Vou. IV. September 25, 1894. 


NOTES ON CROTALUS MITCHELLII. 451 


‘pepper and salt’ appearance. ‘The larger blotches on 
the back are very wide (transversely) and of a brownish 
clay color, becoming brighter posteriorly; the borders of 
these blotches are marked with more or less isolated 
blackish spots. In Dr. Street’s report the paleness of 
his specimen is attributed to fading in alcohol, but as Mr. 
Orcutt’s specimens were received quite fresh, it is evi- 
dent that it is the type which is unusually colored, and 
no@inexothers. ~Vhis* pepper and salt style 1s’ the 
coloration of C’. mztchelli7, as exhibited by eight of the 
specimens in the California Academy, and about as set 
forth in the original description. When it has been said 
that the other specimens of C. mztchel/iz in the California 
Academy collection, from Las Huavitas and Sierra El 
Taste, Lower California, are both decidedly red, as de- 
scribed below, it will be seen that there remains no color 
distinction between the supposed two forms. 

In regard to the second and third distinctions, Dr. 
steqneser “has written (ec) p.v167 jx °° The “original 
character relied upon for the distinction of these two 
species, viz., the number of loreals, there being one in 
the type of C. mztchellit and four in that of C. pyrrhus, 
breaks down upon an examination of the specimens which 
have come to light since. In this respect Mr. Orcutt’s 
larger specimen is particularly interesting, inasmuch as 
on one side of the head it has a very long lower pre- 
orbital, the condition which obtains in C’. mztchelliz, while 
on the other side this plate is divided as in the other 
specimens of C. pyrrhus.’’ The worthlessness of these 
characters is further shown by the great variation in the 
number, size and shape of these plates in the Academy 
specimens, as described below. 

The fourth distinction is scarcely worthy of mention, 
there being so much variation in the shape of the rattle 


452 CALIFORNIA ACADEMY OF SCIENCES. 


in other species. The series of C’. mztchelliz shows it to 
be valueless as a specific character, the difference in 
shape being perhaps due to the presence or loss of its 
terminal segments. 

The fifth and sixth points of difference likewise prove 
to be untenable. Four of the ten specimens which I have 
been able to examine have sixteen labials, two have fif- 
teen, two fourteen, and two have fifteen on the right side 
and sixteen on the left. The number of smooth rows of 
scales varies from none to two. 

The original distinctions between C. mztchellit and 
C. pyrrhus are thus all disposed of, but Dr. Stejneger 
adds (l.c. p. 167): ‘‘I have not the type of C. mztchelliz 
at hand now, but a second specimen was collected by 
Mr. L. Belding at La Paz, L. C., in 1882, and, judging 
from this, the chief difference seems to consist in the 
double row of small scales interposed between the rostral 
and the prenasal, while in all the known specimens of 
C. pyrrhus there is only a single series. By this means 
the nostrils in C. mztchellit appear to be placed further 
back, and the space between nostril and eye is corre- 
spondingly shortened.”’ This character also fails upon 
an examination of a larger series, as is shown in the fol- 
lowing notes on the specimens before me:

Bryant, Feb., 1889. Right side: One loreal; lower pre- 
orbital long; two series of scales between nasal and ros-

PHRYNOSOMA SOLARIS, WITH A NOTE ON ITS 
DISTRIBUTION. 


BY JOHN VAN DENBURGH. 


On page 229 of his ‘‘ Catalogue of the Specimens of 
Lizards in the British Museum’”’ (published in 1845), 
J. E. Gray, in the enumeration of specimens of Phryno- 
soma coronatum, wrote ‘‘d—Adult, in spirits. The 
spines on the occiput forming a continued frill. Cali- 
forma. -27..solanes: Gray, Bo Mi: 

This description, though so short, states the character 
which separates the species, now universally known as 
Phrynosoma regale, from all other known members of the 
genus. Since the A. O. U. Code expressly says that an 
identifiable description is sufficient for the establishment 
of a specific name, and since it was not until 1858 that 
Girard* described the same species under the name of 
P.regale, the latter is a synonym of, and must give place 
to, P. solarts Gray. 

It seems strange that this name has been so generally 
ignored by herpetologists since Gray. Indeed, Cope 
appears to be the only author who mentions it at all,f 
and he merely as a synonym of P. rega/e, overlooking 
the fact that P. so/arzs is much the older name. 

Boulengert mentions the only specimen in the British 
Museum under the head of P. rega/e, although it is doubt- 
less Gray’s type of P. solaris. 

A specimen in the collection of the California Academy 
of Sciences, from Las Animas Bay, Lower California, 
considerably extends the known range to this species. It 
appears to differ in no way from Arizonan specimens.

DESCRIPTIONS OF FOUR NEW POCKET MICE FROM 
LOWER CALIFORNIA, COLLECTED BY WALTER 
E. BRYANT. 


BY DR. C. HART MERRIAM. 


Some time ago Mr. Walter E. Bryant sent me a col- 
lection of Pocket Mice, obtained by himself during his 
explorations in the Peninsula of Lower California. The 
collection comprises 40 specimens (skins and skulls), 
chiefly from the Cape Region and adjacent Islands of 
San José and Santa Margarita, and also from Comondu 
near the central part of the Peninsula. Critical examin- 
ation of this material shows it to contain four unde- 
scribed forms, all in the sub-genus Chetodipus, three of 
which belong to the spzzatws group—previously known 
from a single species inhabiting the Colorado Desert. 
The fourth is a small representative of the Penzcrllatus 
group, the range of which is thus carried southward to 
San Jorge, near Comondu. Unfortunately only a single 
specimen was obtained, the large series from Comondu 
consisting wholly of a member of the spzvatus group in- 
termediate between spzvatus and peninsule. ‘The largest 
and handsomest of the new species was found on San 
José Island, and it gives me much pleasure to associate 
with it the name of Mr. Bryant, who has done more than 
all others to make known the fauna of this part of 
Mexico: 

The accompanying figures belong to the U.S. Depart- 
ment of Agriculture. Permission to use them in the 
present connection was granted through the courtesy of 
Dr. Chas. W. Dabney, Jr., Assistant Secretary of Agri- 
culture.

THE ODONATA OF BAJA CALIFORNIA, MEXICO. 


BY PETER SP CALV ER. 


University of Pennsylvania, Philadelphia. 


(With Plates xv, xvi, xvii.) 


In January, 1893, I was offered for examination a small 
collection of dragon-flies from Baja California belonging 
to the California Academy of Sciences and was asked to 
prepare a memoir upon the subject. Upon my acceptance 
of this proposal, dry specimens collected by Mr. Charles 
D. Haines in various localities, and others in alcohol, 
mainly from San José del Cabo, were sent tome. The 
examination of this lot was well nigh completed when, in 
December, 1893, a much larger collectionin alcohol, made, 
as the labels showed, mainly by Dr. Gustav Eisen, in the 
Cape Region, in September and October, 1893, was re- 
ceived by me. No further collections being then contem- 
plated by the Academy, this paper was completed, but in 
January, 1895, I received additional collections from the 
Cape Region made by Dr. Eisen and Mr. Frank H. Vaslit 
in September, 1894. The total number of specimens 
which I have thus been able to examine has been over 
2600, representing forty species. 

The objects of this paper are: 

1. To give a complete list, with localities, of the Odo- 
nata of Baja California. If we except two or three brief 
notices of a line each, nothing has hitherto been published 
on the dragon-flies of this region. 

2. ‘To describe and figure such of the species as had 
hitherto not been sufficiently illustrated. 

3. To determine the amount of variation in structural 
details, especially in the venation of the wings, assumed 
to be of generic character. For lack of time, I have not 


included the collections made in September, 1894, in es+ 
2p Srer., Vou. IV. ( 31 ) February 19, 1895,

timating the amount of variation, except where the con- 
trary is expressly stated. 

A brief summary of the results obtained follows. 

1. The Mexican territory of Baja California, com- 
prising the peninsula of Old or Lower California, is some 
750 miles long, and stretches in latitude from 32° 34’ N 
to 22° 50° N. Its lower portion, the Cape San Lucas 
region, thus lies within the tropics. Of this Cape Region, 
Mr. T. S. Brandagee states: ‘‘ The Flora of the coast is 
subtropical and a considerable portion West Indian, many 
of the plants perhaps introduced; that of the elevated 
regions is largely Sonoran.”’ 

Collections of Odonata were made at the following 
places:

Mr: Haines; at El Rosario 30° 7° IN, 1257/38 Wee

Anax Junius, Pantalahymenea, Libellula saturata, Diplax 
corrupta, Mesothemts simplicicollis—are distributed over 
a considerable part of temperate North America, espec- 
ially the western part. Dythemzs russata is only known 
elsewhere from Arizona, Dyth. mendax from Texas. 


* New species. 


466 CALIFORNIA ACADEMY OF SCIENCES. 


Anax Walsinghamt, Diplax illota, Ischnura exstriata, 
Z. cervula and Octogomphus specularts are Pacific Coast 
species, the last three being known elsewhere from Cal- 
ifornia only. Argvaagriotdes and A. vivida also inhabit 
California and Texas. Eighteen species are thus chiefly 
Nearctic in distribution, although all are not confined to 
that province, while some may be entitled to rank as 
‘¢ Sonoran.’’ 

Species of mainly Neotropical distribution, eighteen in 
number, are Argva cuprea, A. wenea, Pseudoleon super- 
bus; Enallagma cecum, Ischnura Ramburii var. credula, 
Tramea onusta, Orthemis ferruginea, Micrathyria didyma, 
M. Hagentt, M. equalis, Cannacria furcata; Archilestes 
grandis, Erythragrion salvum,; A¢schna lutetpennis, 4. 
cornigera, Tramea longicauda, Dythemts sterilis, Macro- 
thems imitans. Of these, the first three are confined to 
Mexico, the second group of eight occur in the West 
Indies and elsewhere, the last five were not hitherto known 
to exist outside of South America. 

Lastly, Hnallagma Eisent, Macrothemis tnequiunguis, 
and 7yrzthemis basifusca, all here described as new, are, 
according to our present knowledge, restricted to Baja 
California, while Pantala flavescens is almost world-wide 
in distribution. 

22 nox species, (INios23,.05.11, 29, 32, 33) OF the, pue- 
ceding list) from Baja California have been described as 
new. for a considerable number descriptions have been 
given which are much fuller than those previously exist- 
ing. Structural details have been illustrated for 39 of 
the 40 species, the figures having been made from speci- 
mens from Baja California, except in the cases of Octo- 
gomphus specularts and Cannacria furcata. A few species 
from California, U. S. A., sent with the others, have, for 
obvious reasons, been noticed, including descriptions and 


ODONATA OF BAJA CALIFORNIA. 407 


figures of two new species, J/schnura? erratica and 
schna californica, while special mention must be made 
of the reported occurrence in California of Calopteryx 
maculata not hitherto known west of Kansas, Euthore 
fasciata of Venezuela and Colombia, and Epophthalmia 
elegans of China and Japan (see the appendix). 

3. The generic variations given are, first, variations 
from conditions assumed by other writers to be SeneLics 
second, variations from those adopted in this paper as 
generic. They are to be found under the respective 
species. 

A few words should be said on the specimens preserved 
in alcohol. Dr. Eisen having written that collections 
could be made in that way, I suggested that the insects 
should be placed at once in strong, warm alcohol. The 
result has been to preserve the bright and brilliant colors 
of these dragon-flies in a most gratifying way, and it is 
difficult to believe that after a lapse of one year any con- 
siderable fading has taken place. Such magnificent 
colors as those of Anax Walsinghamt, A&schna lutetpen- 
nis, Libellula saturata, etc., have thus been as available 
for description as if from fresh individuals. It should be 
stated that, except when under examination, the speci- 
mens have been kept in alcohol and in the dark. 

I desire to acknowledge the valuable assistance rendered 
me by the Baron Edmond de Selys-Longchamps, of 
Liége, Belgium, on the difficult genus Areva as mentioned 
in the text. Mr. Samuel Henshaw has done me the great 
kindness of comparing specimens of Euallagma Event, 
Dythemis sterilis and Trithemis basifusca with the collec- 
tion in the Museum of Comparative Zoology at Cambridge, 
Mass.

Three males, two females, Comondu, March, 1889, 
by Chas. D. Haines. 

They differ from the types by their smaller size (abdo- 
men 428.5 mm., 224, hind wing 6 ? 22.5—23.5), less 
number of antecubitals (17-21), and the lesser extent of 
the basal red spot on the wings of the males, which reaches 
but little more than half-way from the base to the nodus, 
instead of four-fifths. Nevertheless they do not appear 
to differ specifically from more typical individuals from 
Shasta County, California, in the collection of the Ameri- 
can Entomological Society in Philadelphia. Inthe writer’s 
collection are specimens from San Bernardino, California, 
by Mr. P. C. Truman, which are similar to those from 
Comondu. 

Californica is characterized by the absence of a ptero- 
stigma in both sexes, and of red spots at the tips of the 
wings of the male. Baron de Selys wrote (/. c. 1873) 


474 CALIFORNIA ACADEMY OF SCIENCES. 


‘‘ It appears decidely impossible to separate specifically 
californica from basalis, which itself is probably only a 
race of americana. The forms are identical and the 
coloring of the wings is the same in the first two of these 
nominal species. Ca/rfornica only differs from dasalzs 
by the absence of the pterostigma...... and has hitherto 
only been observed in California where it is found at the 
same time as the type of dasalzs.”’ 

One male from California, also sent by the California 
Academy, is perhaps to be referred to Walsh’s ¢exana 
with which the dasa/7s of Hagen’s Synopsis of 1861, p. 
60, is said to be identical. A male from Denver, Colorado, 
by Mr. E. V. Beales, in the writers’s collection has the 
abd. 34.5, h. w. 24, and a very small pterostigma—smaller 
than in any eastern or Texan specimens of americana, 


scelerata, texana, etc.; otherwise very much like ca/zfor- 
nica. Lastly Hagen (1875) cites californica from Mon- 
tana. 

A number of the species of /7eterzna created by Walsh 
can not, in the writer’s opinion, be maintained as such, as 
an examination of a considerable series of individuals 
shows that those characters by which he separated them, 
viz.: the extent of the basal red spot on the wings and 
the minute structure of the median internal tooth of the 
superior appendages of the males—are very variable. 
fT. scelerata Walsh and f7. texana Walsh are therefore 
merely pterostigmatous variations of americana Fabr., as 


pseudamericana Walsh has long been recognized to be, 
while ca/zfornica is the western apterostigmatous form of 
the same species.

a stripe from each eye to the side of the occiput, where it 
is connected with the preceding stripe; a mid-dorsal 
band on the prothorax, but often leaving small median 
blue spots—two on the middle and one on the hind lobe; 
a mid-dorsal thoracic band whose width is little if any 
more than that of the blue remaining on either side of 
itself (2. e. blue predominating on thoracic dorsum); a 
humeral stripe, forked in its upper half, the posterior 
branch diverging, running upwards and slightly back- 
wards, but not reaching the base of the front wing, some-

In his classification of the ‘‘ grand genre Agrion”’ (/.c. 
1876), Baron de Selys divides the ‘‘ subgenera ”’ in which 
there is ‘‘no spine or acute point at the apex of the eighth 
segment of the female underneath,’ into two groups as 
follows: 

‘< rst section: Lower sector of the triangle arising in 
front of the basal postcostal nervule. 

2d section: Lower sector of the triangle arising at the 
basal postcostal nervule or hardly in front.”’ 


484 CALIFORNIA ACADEMY OF SCIENCES. 


Asa matter of practice, the writer has found it con- 
venient to paraphrase these two characterizations in this 

I. Postcostal vein separating from the hind margin of the wing® at 
least as far in front of the basal postcostal cross-vein as the latter is long. 

II. Postecostal vein separating from the hind margin of the wing at the 
basal postcostal cross-vein or at less distance in front than the latter is 
long. 

The genus Erythragrion Selys belongs to the second 
of these two sections. It having been noticed that the 
specimens from Baja California varied with respect to 
the point of separation of the postcostal vein, the varia- 
tions were carefully tabulated, as shown below, together 
with some other species for comparison. The table 
refers to the front wings only.

cent. of the females vary in both front wings to such an 
extent as would place them in de Selys’ first section and 
therefore outside of Erythragrion. The comparison with 
Pyrrhosoma is interesting from this consideration; 
Pyrrhosoma belongs to the first section, but it seems 
extremely doubtful whether there is any character which 
can be used to separate it generically from Erythragrion 
other than the one drawn from the point of separation of 
the postcostal vein. Now that the well-marked tendency 
in &. salvum towards the Pyrrhosoma character is 
known, can Erythragrion be maintained as a distinct

middle of base of labrum; the greater (basal) part of

behind the blue postocular spots, these postocular spots 
being cuneiform and connected by an uninterrupted, blue, 
occipital stripe; the dorsum of the prothorax, leaving, 
however, the anterior and posterior borders, and on the

at its upper end where it is narrower and connected by a 
black line with the mid-dorsal stripe just in front of the 
antealar sinus; antealar sinus, except at its anterior 
margin which is blue; a short stripe at the upper end of

angular dilation before the apex—to a round apical spot 
connected by an apical tail with the apex of the segment;

on the basal half, and a broader spot or band on the apical 
fourth; 4-6 similar to 3, sometimes the basal and apical 
spots of 6 united by a narrow line; 7 almost entirely, 
except a narrow, transverse, medially-interrupted, basal, 
blue ring, which also exists on 3-6; 8-10 blue, 8 with a 
minute, mid-dorsal, basal point, 10 with a narrow median 
stripe, black.

a small black tubercle at each side of excision. Superior 
appendages longer than ro, viewed from above divergent 
except at apex, lamellate, obscure and pale in color except 
along the apical and superior margins which are black. 
Viewed in profile each appendage becomes slightly wider 
to the apex which is truncated almost at right angles with 
the superior margin; on the inferior margin in the basal 
half of the appendage is a well-developed, lamellate tooth, 
directed downwards; the margins of this tooth are con- 
vergent, the apical margin being the more oblique to the 
appendage so that the apex of the tooth is bluntly pointed.

8-10 postcubitals, 3 discoidal cells, nodal sector rising 
from between fourth and fifth postcubitals to between 
fifth and sixth. Hind wings with 7-9 postcubitals, 3 dis- 
coidal cells, nodal sector arising at the fourth, or between 
the fourth and fifth postcubitals.

An interesting peculiarity is the variation in the extent 
of the black marking on the second abdominal segment, 
both extremes of which, and some intermediate forms, 
are to be found in the specimens from Baja _ Puris- 
ima. The grouping employed by Baron de Selys for 
the species of Anal/lagma ‘* black spot of the second seg- 
ment in form of an [apical] T’’ and ‘* black spot of the 
second segment a dorsal band,’’ is therefore no longer 
so decisive. In addition to the form of the appendages, 
a specific character is to be found in the presence of the 
lanceolate, basal, black spot on 3-6. 

This species is named after Dr. Gustav Eisen, the well- 
known student of Oligochatous worms, to whose labors 
so much of the present paper is due. Mr. Samuel Hen- 
shaw has compared a male of this species with the 
Enallagmas in the Museum of Comparative Zoology at 
Cambridge, Mass. (Dr. Hagen’s collection), and writes 
that this species is ‘‘ not in the collection.’’

In the typical Raméurzz7, a common species along the 
eastern coast of the United States, the eighth abdominal 
segment is blue, the ninth black; in credu/um ‘‘ seginent 
8 entirely, 9 base only blue,’’ both statements referring 
to males and the black females. 

The above cited specimens are of variety credula; 8 is 
blue entirely or with a very narrow, transverse, basal, 
black ring, articulation between 8 and g black; 9g blue 
with an apical, dorsal, black spot occupying from one- 
third to more than one-half the length of the segment on 
the mid-dorsal line, but less on the sides—besides which 
there is in some individuals a small, mid-dorsal, basal, 
black spot, which may be united with the black at the 
apex by a narrow, or even a broad, band. Two of the 
black females have these basal and apical spots on 9 
separated by a blue interval equal to one-fifth the length 
of the segment, while the remaining black female has 
these spots united by black. The orange females are 
colored as in typical Aeamburz? (having no black humeral 
stripe, 1 and base of 2 orange—see Calvert /. c.), the ex- 
tent of the black on 2 is variable and on 10 varies from 
nothing to the entire dorsum. That all are to be referred 
to Heamburii is shown by the fact that in other respects 
and especially the superior appendages of the male, they 
quite agree with the typical form. It is worthy of note 
that the color of the superior appendages varies from yellow 
in the male from Comondu, through brown to black in 
typical Ramburiz. The defixum Hagen (not Selys) is the 
same as this variety, see under /. perfarva, post.

frons anteriorly, postocular spots, a complete antehumeral 
stripe each side, sides of thorax (except a superior black 
line on the first lateral suture and a complete line on the 
second), pectus, abdomen below, apical dorsal half of 1, 
a wavy, transverse, apical band on 2, a dorsal band on 
the apical five-sixths of 7, 8 and 9 (except a lateral black 
band on the side of each, reaching from base to apex, 
those of 8 united by a narrow, transverse, basal, black 
band and of 9 by a transverse, apical band in the Cali- 
fornian male, but not united on either 8 or 9 in the Wash- 
ington example), feet except an anterior black stripe. A 
narrow, transverse, basal, interrupted, yellow ring on 3-7. 
Hind margin of prothorax rounded, emarginate in the 
middle. Forked process on 10 about half as high as 10 
itself; viewed in profile, it commences near the middle of 
ro at an angle of about 50°; forked in less than its apical 
half, branches divergent at 90° or more. 

Superior appendages black, very short, one-fourth as 
long as 10, tubercular, with a slender, inner, inferior pro- 
longation reaching to the base of the inferior appendages. 
Inferior appendages two-thirds as long as 10, similar to 
those of exstrzata, but with the apical process a little 
more robust and curved upwards as well as inwards at 
the extreme tip. 

Wings clear. Front wings with 9-12  postcubitals, 
nodal sector arising near fifth antecubital, on hind wings 
near the fourth. Pterostigma of front wings surmounting 
alittle more than one cell, very oblique, nearly equilateral, 
bicolored, inner half blackish, outer half reddish; of the

2 Differs from 6 as follows: a transverse, basal, black 
stripe on labrum, 8—9 black in the Californian female, similar 
to those of the Washington male inthe Washington female ; 
hind margin of prothorax distinctly bilobed; a very dis- 
tinct, transverse, erect, triangular lamella behind each 
mesostigma; no apical ventral spine or acute point to 8; 
appendages black, three-fourths as long as 10; front wings 
with 12-13 postcubita's, nodal sector arising at sixth 
postcubital in front wings, at fifth in hind wings, in the 
Californian female only; pterostigma luteous, of nearly 
equal size on front and hind wings, some double cells 
after it.

To write of the female that it possesses no ventral spine 
to the eighth segment is almost equivalent to excluding 
this species from Ischnura, but it is here so referred, with 
much hesitation, for the following reasons: 

t. As shown by the descriptions and figs. 1 and 2 pl. 
xv, the appendages of the males of erratica and exstriata 
are very similar, hence if ewstvzata be an Ischnura it is 
difficult to believe that erratzca is not closely allied. 

2. Erraticaé possesses the Ischnurine characters of 
pterostigma and bifid process on Io. 

3. If the reference of exstvzata to Ischnura be correct, 
light is thrown on the absence in erratica 2 of the ventral 
spine to the eighth abdominal segment by the circumstance 
that in extrzata@ (g. v.) the same spine is very short. 

4. It seems improbable that what have been above 
described as evratica male and female belong to different 
species, for not only do their colors resemble each other, 
but the pair from Washington were sent by the collector, 
Mr. Kincaid, to the writer enclosed in the same envelope 
as if taken while pairing.

Baron de Selys described an ‘‘ /schnura defixa Hagen,’’

Selys and ferparva are not distinct species; 2, that de- 
fjixum Hagen is different from these two forms, and 3, is 
a variety of ARamburit Selys, not distinct from variety 
credula Hagen. 

1. De Selys’ description of his defixa is comparative 
only, that of perparva is detailed, and from it the im- 
portant characters common to both may be learned, viz.: 
Pterostigma oblique inside but not outside, almost rounded 
beneath, surmounting almost one cell on the superiors,

half shorter and much smaller on the inferiors. <A nar- 
row, yellow, antehumeral stripe. Abdominal segments 8 
and 9 clear blue with a lateral black ray, not touching 
the apex, very short on 9. Superior appendages half 
shorter than the last segment, thick, truncated at the 
apex which is bent downwards. Inferior appendages 
flattened like a goose’s foot, forming three * points, one 
external and superior, one internal and subbasal, and one 
median, slender, longer and curved inwards. 

The differences between defixa and perparva are then 
stated to be—

Baron de Selys remarks (/. c. p. 262) that it is possible 
that his defiva ‘* may be only a larger race or variety of 
perparva, and that the difference in the color of the 
pterostigma of the superiors and of the feet may result 
from the specimens of defiva being very adult, while 
those of Perparva may be newly transformed......It is 
probable that this species [7. e. defixa Selys] is the 
depxum of Dr. Hagen. I dare not refer it there with 


“The presence or absence of the third or median point appears to be a 
variable character not of specific value.

certainty because I have not seen the specimen, and 
because in his correspondence Dr. Hagen thinks that his 
species cannot be maintained. After that I had at first 
named it 7. furcula.” 

The evidence here presented to prove defiva Selys not 
distinct from Perparva aims to show that the differences 
above tabulated are not constant. Two males from Cali- 
fornia ab. 19-20, h. w. I12.5-13, agree with 2, 3, 4 and 
5 of defixa, have only the merest trace of an internal 
basal tooth to the superior appendages, have the right 
inferior appendage bifid, the left trifid. Two other males 
from Calitornia and one male from Olympia, Washing- 
ton, ab. 20-22, h. w. 12.5-13.5, agree with 2, 3, 4 and 
5 of defiva, have both inferior appendages bifid, black 
stripes of right and left sides of 8 connected by a trans- 
verse basal ring; in the Washington male the upper outer 
point of the left inferior appendage is itself bifid. One 
male from southern Texas, ab. 19.5, h. w. 12.5, agrees 
with de#xa, the black lateral stripes on 9 reach the apex. 
One male from Denver, Colorado, ab. 20.5, h. w. 12.5, 
agrees with 2, 5 and 6 of ferparva, 3 and 4 of defixa, 
both inferior appendages bifid. Another male from 
Colorado, ab. 18, h..w. 12, agrees with 2, 3, 4 and’5 of 
defixa, 6 of perparva, both inferior appendages trifid, 
upper outer point of left appendage itself slightly bifid. 

2. That defxum Hagen is different from perparva 
and defiva Selys is apparently indicated by the following 
expressions in Hagen’s original description of defivum 
(Syn. Neur. N. A. p. 80); 8 and 9 are said to be ‘‘ blue, 
at base a little black,’’ instead of using such an expres- 
sion as ‘‘8-9 blue, with a black stripe each side’’ (J. ¢. 

76) as for Ramburit Hag. (=vertical’s Say), perparva 
and consequently defxva being similar to ver¢zca/7s in this 
respect. The superior appendages of defixum are said 


ODONATA OF BAJA CALIFORNIA. 497 


to be ‘‘ two-branched, external branch conical, straight, 
internal branch longer flat,’’ a form of appendage quite 
different from that described for ferparva by de Selys. 
The inferior appendages of defixum are ‘‘ unguiculated, 
longer, oblique, recurved,’’ an expression similar to that 
employed for Ramburi (p. 76) and therefore hardly 
likely to have been applied to such a trifid or bifid ap- 
pendage as exists in perparva. 

3. Lastly it is believed that a comparison of Hagen’s 
original descriptions of defivum and credulum, justifies 
the assertion that both apply to the same insect, since it 
has been shown under /schnura Ramburi var. credula 
(see ante in this paper) that the extent of the black on 8 
and g is a variable quantity. Since credulum is recog- 
nized as not specifically distinct from /tamburi Selys 
(zners Hagen, 1861), defxum Hagen must also be referred 
there:

A comparison of all the present material with the de- 
scriptions of de Selys, 1873, and Hagen, 1874, follows: 

6 Frons olive, its superior, transverse, brown band in 
front of the ocelli produced but little or not at all in the 
middle. Nasus paler than the frons, yellowish-green, 
obscure in the middle, rhinarium still paler, lips colored 
nearly as nasus. Vertex brown, behind the two posterior 
ocelli is a greenish area not reaching the occiput how- 
ever. Hind margin of occiput very slightly convex. Two 
yellow spots behind each eye, in some cases confluent. 
Inferior ‘‘ humeral’ stripe or line (really antehumeral, 
thus making two antehumeral stripes) present or absent; 
in the former case united with a spot above, in the latter 
case there are merely the two ‘‘ superior yellow spots ”’ 
which are, strictly speaking, one ante-, the other post- 
humeral. As compared with Mon. Gomph. p. 202, the 
yellow antehumeral bands unite with the yellow of the

anterior mesothoracic border. Sides of thorax, in fresh 
alcoholic specimens, bluish, becoming brownish when 
dried: second lateral suture with a brown stripe. Abdo- 
men: the ‘‘ dorsal spear-shaped’’ fascia not reaching 
the apex of 3; 8 with a small, triangular, yellow spot 
each side at base of dorsum, and on each lateral surface 
a basal and a smaller apical spot; a small, yellow, apical 
spot on each side of 9; a yellow streak on the middle of 
the inferior lateral margin of 3-7. 

In none of the descriptions of the superior appendages 
(which are about twice as long as 10) is mention made of 
a longitudinal carina on the outer margin of the inferior 
surface, extending from the base to not quite as far as 
the middle of the appendage; this carina is finely dentic- 
ulated, its course is convex exteriorly when viewed from 
below. A similar carina is shown for P. complicatus and 
P. costalés in Pl. 11, Monos.Gomph. Onithe inneredee 
of the branches of the inferior appendage are two to 
four small, superior teeth immediately before the apex. 

Femora above reddish-brown, yellowish below, tibize 
blackish, knees yellow. The first tibiz have a pale in- 
ferior carina, somewhat similar to that of the Corduline 
males, which extends for almost their distal half. Similar 
carine are to be found in males of Progomphus integer, 
P. gracilis, Gomphoides stigmata, Cyclophylla elongata, 
and perhaps others of this legion. Rudiments of such 
a carina are present on the first tibia of Cordulegaster 
males. 

Wings with basal brown spot extending one-third of 
the distance to the first antecubital. 

? As compared with the é¢, has the colors of the face 
less obscure, somewhat paler; green on vertex in one 
case reaching back to occiput; hind margin of occiput 
slightly more convex; a very narrow, inferior, ‘‘ humeral ”’

(in reality antehumeral) stripe present, which may, as in 
one female, unite above with the superior spot; lateral 
basal and apical yellow spots on 8 confluent in two fe- 
males; apical, lateral spot on 9 larger; streak on middle 
of inferior, lateral margin of 3-7 greenish rather than 
yellowish; dorsum of 10 mostly yellow, basal third or 
fourth brown. Appendages about twice as long as 10, 
yellow, sharply pointed, extreme tip black in three 
females; de Selys’ description of 1878 speaks of these 
appendages as ‘‘as long as 10.’ No inferior carina to 
first tibia. Brown spot at base of wings reaching to 
basal subcostal cross-vein. Vulvar lamina more than 
one-third as long as 9 on the sides, about one-fourth as 
long at the middle, with a rounded median emargination 
extending almost to the base of the lamina, and a shal- 
lower emargination on each side, making three in all.

From the careful description of exc7sa Brauer (synony- 
mous with /ufezpennis according to Hagen), these three 
males differ as follows: labium bluish instead of yel- 
lowish; suture between the eyes much more than double 
as long as the occiput, being nearly as long as the com- 
bined length of frons and vertex, measured along the 
mid-dorsal longitudinal line; first femora blue inferiorly: 
mid-dorsal, longitudinal, abdominal stripe blue instead of 
yellow; 9 with a mid-dorsal, apical, triangular, blue spot, 
a similar smaller one on r0 in the males from Mesa Verde 
and Miraflores; superior appendages a little longer than 
g+ 10: costa with a yellowish line to the nodus.

ing a distinct, inferior, subbasal tooth, the pterostigma 
shorter and yellow, the reticulation of the wings more 
yellowish. Two other South American species described 
by Rambur, doxarvenszs and Marchal, are personally un- 
known to the writer; perhaps they are closely allied, but 
Rambur’s descriptions seem to indicate specific differ- 
ences from californica. In describing californica as new, 
reliance has chiefly been placed upon the facts that Dr. 
Hagen considered the species as distinct, that the allied 
species referred to above were known to him, and that 
the present writer possesses one of Dr. Hagen’s types 
given by him in July, 1890.

Differs from Brauer’s description in wanting the black 
line on the fronto-nasal suture, by having a larger pteros- 
tigma (2 mm. in Brauer’s specimens), and the (blue) 
thoracic stripes narrower. Hagen (/. c. 1867) mentions 
that ‘‘die Flugelspitzen der Mannchen sind oft hyalin 
ohne Braunung’’; such is the case in all four of these 
specimens. 

Sternum of 1 with a spinous tubercle as in californica, 
but more prominent. Superior appendages of the male 
with the apex terminating in a short, acute process di- 
rected downwards, the superior, median, longitudinal

Of the specific characters assigned to this species by 
Hagen (/. c., 1861) some are not constant, viz., the 
fuscous basal spot of the hind wings often attains the 
front margin, as it does in all the above specimens; the 
inferior appendage of the male, instead of just reaching 
to the denticulated portion of the superiors, may extend 
beyond it, as in 7. carolina. Front wings with 11-13 
antecubitals, S-1o postcubitals. Hind wings with 7-8

24 San José del Cabo, one May, the other October, 1893. 

Labrum black in the middle, brownish each side; la- 
bium brownish-yellow, middle lobe only black; epistoma 
brown; frons superiorly and vertex with a metallic blue 
reflection. ‘Thorax light brown, a black spot on the 
lower parts of the mesepimeron and of the metepimeron, 
and a black line on the upper ends of the humeral and 
second lateral sutures. Abdomen (probably reddish-) 
brown, 8-10 blackish dorsally. 

Superior appendages reddish-brown, 3.5 mm. long and 
hence longer than 9-10 (2 mm.) but not as long as 8 + 
g+10(4.5 mm.), with an inferior row of about ten denti- 
cles on the basal half. Inferior appendage half as long 
as the superiors, reaching beyond the denticles. An- 
terior lamina least prominent, its apex slightly bilobed; 
hamule more prominent than lamina or genital lobe, sim- 
ple, apex acute, curved outwards to form a hook. 

Wings slightly smoky when held over white paper, 
veins reddish near base, brownish apically. Hind wings 
with a brown basal band, veined with yellowish, com- 
mencing a little in front of the submedian vein, reaching 
within a cell of the anal ‘‘angle’’; outer edge "of wis 
band nearly on the level of the median cross-vein, inner 
margin not attaining the anal margin of the wing, which 
is here bordered by a pale obscurely-yellowish tract,

3-6 cells wide, from the membranule to the anal angle. 
Front wings with four rows of post-triangular cells, 12-13 
antecubitals, 10-11 postcubitals. Pterostigma ochre- or 
reddish-yellow, 3 mm. long in front wings, 2 mm. long in 
hind wings. 

Total length 48. Abd. 32. Hind wing 44 mm. 

Dr) Brauer has characterized (7. ¢., p: Siz) the group 
of 7. cophysa Hag. as having ‘‘four discoidal [post-trian- 
gular] rows, basal spot of the hind wings reaching only to 
the cross-vein of the middle cell’’ (== median cross-vein). 
This group is divided into two sections, the first with the 
anal margin of the hind wings entirely or partly hyaline, 
the second with the anal margin black; /ongicauda is re- 
ferred to the first section. From the sufficiently described 
species of this first section, the two above males differ as 
follows: 

Cophysa Hagen has a large quadrangular dark brown 
spot on the thoracic dorsum, and two, oblique, yellow 
bands on the sides of the thorax. 

Subbinotata Brauer has the hamule not projecting be- 
yond the genital lobe, the sup. app. 6 as long as 8 + 9+ 10, 
inf. app. one-third as long as sup. app., pterostigma longer 
(3 mm.) on hind wings. 

Longicauda Brauer has the sup. app. ¢4 as long as 8+ 
g+10, the general color of the body and of the basal spot 
on the hind wings is blackish-brown. These two males 
may not belong to /ongzcauda, but it seems best to refer 
them here provisionally. Longzcauda inhabits Brazil. 

Insularis Hagen has merely a small hyaline spot on the 
anal margin of the hind wings, the hamule does not pro- 
ject beyond the genital lobe, the sup. app. ¢ are as long 
as 8+9-[ 10. 

The Mexican and West Indian species abdominalis 
Rambur which may be considered to belong to the sec- 


516 CALIFORNIA ACADEMY OF SCIENCES. 


ond section of this group, although the color of the anal 
margin is dark brown, not black, also differs by the frons 
superiorly and vertex red, the pterostigma brownish-black 
or reddish-brown.

De Selys (7. c. 1868) and Hagen (/. c. 1873) give the 
following as specific differences between saturata and 
crocetpennis: 


Saturata. Croceipennis. 
1. Median space and triangle of hind wings 
fuscous. not fuscous. 
2. Veins in first and second costal [= antecu- 
bital] spaces bright yellow. reddish. 


Yellowish-brown of the base of the wings

the pterostigma. stopping at the nodus. 
4. Hamule with inner and outer branches inner branch pointed, 
equally pointed. much longer; genital 


lobe larger. 


ODONATA OF BAJA CALIFORNIA. 517 


Croceipennis is said to be smaller, but to have a longer 
pterostigma; measurements are not given. The expres- 
sion used by Dr. Hagen for saturata, ‘* hamules with in- 
ner and outer branches equally pointed,’’ is misleading, 
as the inner branch in both forms is always longer and 
more acute; in otherwise typical crocezpennis the inner 
branch is more slender and its extreme hook-like apex 
is somewhat more prolonged than in otherwise typical 
saturata, but after an examination of the above mate- 
rial, it seems impossible to establish any specific differ- 
ence. The difference in the size of the genital lobe is 
mainly in width; in males with typical satwrata wings the 
greatest width is less than the length; in typical crocez- 
pennis the width exceeds the length. 

The specimens from San Ignacio agree mainly with 
saturata in wing-coloring, but the intensity of the color- 
ing of the median space and triangle of the hind wings 
varies; the genital lobe is like satwrata. Abd. ¢ 32-33, 
@ 30-32. Hind wing ¢ 38-40, ? 40-42. 

The fourteen males from San José del Cabo (not dated 
and September, 1893) mostly agree with crocecpennis. 
The yellowish- brown on the front wings extends from 
the base to the triangle or to the nodus, on the hind 
wings its apical limit varies from the triangle to beyond 
the nodus. In one male the median space in the hind 
wings is fuscous, but not the triangle; this male has the 
genital lobe narrower than its fellows. The amount ot 
coloring of the wings is not correlated with size. Abd. 
29-32.5, hind wing 35-41. fPter. 5.5-5. 

Of the thirty-five individuals taken at San José del 
Cabo in October, 1893, twenty-five, all males, have the 
wings reddish-brown from base to nodus for almost the 
entire width of the wing; of these twenty-five, some have 
no fuscous in the triangle and median space, others a 


518 CALIFORNIA ACADEMY OF SCIENCES. 


varying amount of fuscous therein. The seven remain- 
ing males have the reddish-brown extending to the trian- 
gles. The three females have the wings reddish-brown 
to nodus but more marked along costal margin, median 
space and triangle of hind wings darker brown. 

The difference above numbered 2 is valueless as a male 
from Los Angeles, Cal., otherwise agreeing with saturata, 
has these veins, red. 

Too many intermediate forms thus appear to exist to 
allow of saturata and crocecpennis being considered as 
distinct. 

The body and especially the abdomen of this species 
is brilliant red in color. 

Distribution. Mexico (Baja California, as above, to 
which Hagen adds Cape San Lucas, Tampico, Cordova, 
Orizaba, Vera Cruz, Tehuantepec), Guatemala, Colom- 
bia?, California (Los Angeles by Dr. A. Davidson), Ari- 
zona, Montana, Yellowstone.

(greenish?) run vertically from the upper to the lower 
surface of the eye (fig. 62). The fourth abdominal seg- 
ment cannot be said to be carinate at all (cf. Kirby /. c.). 
The pterostigma of the teneral male is pale-colored for 
its entire length; in the adult males it is black for its en- 
tire length, as shown in Kirby’s figure; in the females 
and in one adult male, it has the ‘‘ exterior half white 
surrounded with fuscous,’’ as described by Hagen. Con- 
siderable variation exists in the extent of the wing mark- 
ings of the females. 

Front wings with the sectors of the arculus varying 
from a condition in which they are separated from their 
origin to that in which they arise by a common stalk 
whose length may exceed that of the lower piece of the 
arculus; discoidal triangle crossed by one vein in both 
wings of 28 individuals, by two veins in both wings of 20 
individuals; 18 individuals have one cross-vein on one 
wing, two on the other; 2 have three and one, 2 have 
three and two, 1 has the triangle free on both wings; one 
supratriangular in both wings of 7 individuals, in one 
wing only of 18 individuals, absent in the others; highest 
number of antecubitals 12, of postcubitals 7. 

Hind wings with the discoidal triangle crossed by usu- 
ally one, or in some cases two, cross-veins; one supra- 
triangular present in both wings of 18 individuals, in one 
wing only of 21 individuals, absent in the remainder. 
One ? has the triangle altered to a quadrilateral on both 
hind wings. 

The third joint of the penis is relatively long as com- 
pared with Orthemis ferruginea, Libellula saturata, etc., 
and becomes wider to the apex, which is without the two

The specimens marked a, e, f, g, h, numbering 208 ¢ , 
119 2, were carefully and individually compared with the 
generic characters given in the fore part of this paper for 
Orthemis with the result that the only variation from those 
characters detected was that one supratriangular was 
found in the right front wing of one female, an amount 


ODONATA OF BAJA CALIFORNIA. 521 


of variation which may be estimated at .15 of one per 
cent. Kirby (/. c.) gives as a generic character of Or- 
themis that the internal triangle of the front wings is 4- 
celled * (‘‘subtriangular space consisting of four cells’’), 
and four is indeed the more usual number, but that num- 
ber varies too much to serve as a generic distinction. 
Thus in the same lot of 2084, 119, it was found that 
the internal triangle was 3-celled in both wings of 9 indi- 
viduals, in one wing of 25, and 5-celled in both wings of 
23, in one wing of 55 individuals. Summarizing these 
statistics in another way, the number of cells in the inter- 
nal triangle of the front wings is asymmetrical with re- 
spect to the right and left sides of the body in 80 individ- 
uals out of 327, or 244%4%. Of these 80, 72 have 4-cells 
in one front wing, 3 or 5 in the other, the 3 or 5-celled 
wing being the right one in 43, the left one in 29. Among 
those individuals in which the 3-celled condition exists in 
one or both front wings, males and females are almost in 
equal numbers, but where the 5-celled condition in one 
or both front wings occurs the males are almost three 
times as numerous as the females. 

One cross-vein in the discoidal triangle of the front 
wings is a very constant feature; out of the same 327 in- 
dividuals, two cross-veins were observed in the left wing 
of a single male; a free condition of this triangle was not 


found.

At first it seemed that these specimens represented a 
variety of rufnervis Burm., differing only as they do by 
color and not by any structural characters. Upon Mr. 
Henshaw’s comparing a pair from San José del Cabo 
with Dythemis at Cambridge, he wrote: ‘‘ Appears to 
me nearer to some specimens from Livingstone, Guiana, 
placed with Dyth. sterdlis by Dr. Hagen than it does to 
Dyth. rufinervis. 1 send you one of these by mail.” 
Further study of the specimen sent by Mr. Henshaw 
leads the writer to adopt his conclusion. The following 
description, however, having been previously drawn up, 
is mainly comparative with that of Mr. Scudder (Proc. 
Bost. Soc. N. H. x, p. 192, 1866) for his vznosa = rupin- 
ervis. 

Frons usually ‘‘ olivaceous yellow,’ brown above, la- 
brum in some cases edged with black (Rambur’s descrip- 
tion, Ins. Nevr. p. 91, of conjuncta = rujfinervis, speaks 
of the labrum as black), tip of the vertex slightly con- 
cave, vertex and occiput olivaceous. Thorax brown, 
mid-dorsal carina, a straight antehumeral and a sinuated 
humeral stripe greenish-yellow; a transverse greenish- 
yellow stripe, just in front of the antealar sinus, may or 
may not connect with the two preceding stripes at their 
upper ends, and extends almost to the mid-dorsal carina. 
On the sides of the thorax greenish-yellow may occupy 
the lower part of the mesepimeron, a stripe in front of the 
second lateral suture and the greater part of the metepi- 
meron; or the brown may be reduced to a posthumeral 
stripe, a stripe at the (obsolete) first lateral and one at 


524 CALIFORNIA ACADEMY OF SCIENCES. 


the second lateral suture. Abdomen greenish-yellow, 
3-8 with a black stripe on the mid-dorsal and on the lat- 
eral carina, confluent posteriorly to form a transverse, 
apical band, g-10 entirely black except at articulations; 
or the lateral black bands on 4—7 widened, united at base 
with mid-dorsal stripe, 8-10 black—intermediate forms 
connect these two extremes. 

Superior appendages as long as 9+10, dark brown, 
acutely-pointed, with about four inferior denticles in the 
third fourth of their length. Inferior appendage about 
one-sixth shorter, yellowish except the edges and apex 
which are black, triangular, reaching beyond the denti- 
cles of the superiors. Anterior lamina with margin en- 
tire. Hamule more prominent than adjacent parts, not 
bifid, but with an external basal tubercle which may rep- 
resent the outer branch of other genera, apex acute, 
slightly hooked externally. Genital lobe oblong, of near- 
ly uniform width, apex rounded. 

4 2 Brownish-yellow on base of front and hind wings 
reaching at most to the first antecubital, often not so far; 
the dark brown streaks on the hind wings between the 
subcostal and median and the submedian and postcostal 
veins not apparent, or but faintly visible in a few individ- 
uals. Front wings with 12-15 antecubitals, 7-11 postcu- 
bitals. 

? Black stripes on lateral carine of 3-8 wider than in 
6. Appendages black, longer than tro, a little more 
than half as long as 9, straight, simple, apex acute; anal 
tubercle half as long as the appendages. Vulva marked 
by a distinct semicircular notch at apex of sternum of 8, 
g with a well-marked, mid-ventral longitudinal keel. 

Generic variations noted: the last antecubital contin- 
uous in one wing only of two females; discoidal triangle 


of 3 cells in one wing of one male, in all others, both 
male and female, 2-celled.

also apparently to be referred to ster7/7s, although at first 
the writer supposed them to be adult ve/ov. The differ- 
ences between ve/ow and sferz/is are so slight as to render 
their distinctness as species very doubtful. These 17 ¢ 
have frons and vertex dark metallic blue; thorax and ab- 
domen either pruinose, or with pale markings more or 
less obliterated, such traces as still persist agreeing with 
those of either ster7/7s or velox. Hind wings brownish at 
extreme base, but the apices of the wings barely edged 
with brown (only to about the width of one cell); ante- 
rior lamina projecting but little, hairy; hamule not bifid, 
similar to that of sterz/’s as above: genital lobe longer 
than wide, projecting as far or nearly as far as the ham- 
ule, apex rounded; superior appendages black, slightly 
longer than 9, thickened in the apical third, the thickened 
part with about five inferior denticles, apex acute; infe- 
rior appendage about one-eighth shorter, subtriangular ; 
front wings with 13-16 antecubitals, 8—11 postcubitals, 
triangle with one cross-vein, internal triangle 3-celled 
(4-celled in 2 6 and one wing of 14); hind wings with

‘‘subtriangular space [| =internal triangle] usually free, 
rarely 2-celled, more rarely 3-celled.’’ He further states 
that in the hind wings of the 9 are two post-triangular

4 Closely resembles J/. Hagenz/ in coloring, having 
however the green antehumeral stripe narrower, brown 
stripe on the first lateral thoracic suture not forked, green 
spots on abdominal segments 3-6 narrower—in fact, nar- 
row stripes. Tip of vertex more distinctly bifid than in 
Hagenii. Superior appendages similar, but showing a 
tendency to form an obtuse inferior tooth at the position 
of the last denticle. . 

Distinctive characters presented by the genitalia. An- 
terior lamina bifid to base so that when viewed in front 
it forms a distinct and straight tubercle each side, whose 
apex is narrower than its base and is not denticulated. 
Hamule very peculiar, bifid; that which apparently cor- 
responds to the external branch is greatly prolonged, 
more prominent than any adjacent part, curving forwards 
and ventrally as a lamellate process with its apex extend- 
ing below and a short distance in front of the level of the 
anterior lamina; a short distance before its apex, this 
process is constricted, while the apex is widened into a 
flat plate whose apical margin is denticulated. The ap- 
parent homologue of the internal branch of other species 
is a small, curved, acute spine directed backwards and 
first inwards, then outwards, and projecting ventrally a 
little farther than the genital lobe. Genital lobe small,

projecting equally with the anterior lamina, wider at apex 
than at base. 

A slight yellow cloud at the extreme base of all the 
wings. Front wings with 9-12 antecubitals, 7-8 postcu- 
bitals, discoidal triangle with one cross-vein, internal 
triangle 3-celled (2-celled in one wing of 14 ), 3 post- 
triangular cells, then 2 rows. Hind wings with 7-8

and d7dyma are to be distinguished by the former having 
the abdomen robust and of nearly uniform width, each 
spot on segments 2-6 one-fourth as wide as the dorsum 
of the segment, while d¢dyma 2 has the abdomen slender, 
widened somewhat at the base and before the apex, each

margin distinctly bilobed. 

Feet black, coxe and trochanters brown, first femora 
yellowish below; hind tibiz with 16-20 spines on the in- 
ner side, I1—14 on the outer side. 

Abdomen, viewed from above, not dilated at the base, 
widest at 4, gradually tapering to the apex; much thick- 
ened at the base when viewed from the side; 2 and 3 
with an additional transverse carina; with or without a 
median dorsal black spot on apical half of 8 and 9. 

Superior appendages as long as the last two segments, 
luteous; viewed from above, they are nearly straight, 


ODONATA OF BAJA CALIFORNIA. 549 


slightly constricted after the base, thence gradually dilating, 
especially on the inner side, to two-thirds their length, 
thence tapering to the acute apex. Viewed from the side, 
each appendage is curved downwards in its basal half, 
thence upwards in its apical half; it gradually increases in 
thickness from the base and forms a well-marked tooth 
on its lower surface at not quite half its length; from the 
tooth it gradually tapers to the acute apex; on the lower 
surface between the base and the tooth are eight to 
twelve denticles. 

Inferior appendage half as long, luteous; viewed from 
below, broad, apex more than half as wide as the append- 
age is long and deeply concave from side to side, the two 
lateral apices so formed are upcurved, unguiculate, reach- 
ing distinctly beyond the tooth of the superiors. 

Genitalia of 2 moderately prominent. Anterior lamina 
not quite as prominent as the hamule, thickened at each 
side, apex broad, concave from side to side. Hamule 
simple, lamellate, narrowed in its apical fourth to form 
the acute, somewhat unguiculate apex, which is directed 
outwards and backwards. Genital lobe as prominent as 
the hamule, broader before the apex than at the base. 

Wings hyaline, slightly smoky, reticulation brown, costa 
partly yellow. Pterostigma luteous, narrow, about one- 
fourth as wide as long. Membranule cinereous. A very 
small ferrugineous tinge at the base of the front wings. 
Hind wings with a ferrugineous basal spot extending out- 
wards nearly to the median cross-vein, and from the sub- 
median nearly to the hind margin. Sectors of the arcu- 
lus barely stalked, or not stalked, at their origin in the 
front wings, stalk somewhat longer in the hind wings. 
No hypertrigonals (present in the front wings of I ). 
One median cross-vein, placed nearer the base than the 
first antecubital. Nodal sector hardly waved. Front

wings with 8—10 antecubitals, the last not continuous, 
7-9 postcubitals, triangle with one cross-vein, internal 
triangle of three cells, three rows of post-triangular cells. 
Hind wings with 6 (7 in one wing of 1 4 ) antecubitals, 
7-9 postcubitals, triangle free (one, cross-vein in one wing 
of 14 ), its inner side in the prolongation of the arculus, 
no internal triangle, two rows of post-triangular cells, 
sectors of the triangle arising from the same point. The 
male from Miraflores has, in the left front wing only, one 
basilar cross-vein which is continuous with the median 
cross-vein. 

2 Differs from the male as follows: Abdomen not so 
strongly dilated at the base when viewed from the side. 
Appendages a little shorter than 9 + 10, luteous, simple. 
Vulvar lamina very small, not extending beyond 8, notched 
in the middle of its margin. The San José female, more- 
over, has the face pale green, becoming yellowish on the 
lips, the thorax less reddish, pale greenish around the 
wing-bases, the last antecubital continued to the median 
vein on both front wings.

These specimens agree in all points with the generic 
and specific descriptions of Hrythemzs furcata Hag. /. c. 
Erythemis, as it has been defined by Mr. Kirby in his 
‘¢Revision of the Libelluline’’ (Trans. Zool. Soc. Lon- 
don, xii, p. 304, 1889), has, among other characters, the 
sectors of the arculus distinctly stalked, hind wings with 
the sectors of the triangle widely separated at their origins 
and therefore three rows of post-triangular cells. /wr- 
cata Hag. therefore does not belong here, as has been 
pointed out by Dr. Karsch /. c., but to Cannacria Kirby 


ODONATA OF BAJA CALIFORNIA. 551 


(irans. cited, p#300). The characters given for Can- 
nacria agree entirely with the present specimens, save 
that the abdomen is stated to be as long as the hind 
wings.) Dr) Warsch(/;e5)p.. 361) further states, ** Karby. 
has founded the genus Cannacria on a species described 
as new, C’. dateszz, which Iam not able to separate spe- 
cifically trom a typical male specimen of Arythemzs fur- 
cata Hagen from Bahia (from Gomes) in the Kénigliche 
Museum fiir Naturkunde at Berlin; only that there are 
in the hind wings not 6, but 7 antenodal cross-veins as in 
the figure accompanying Kirby’s description.’’ 

The writer is not satisfied as to the specific identity of 
furcata Hag. and batesed Kirby (Trans. cited p. 341, pls. 
ii f. 1, lvii f. 9) for the following reasons: 1. The figure 
of the 6 appendages of daz¢eszz does not show the tooth on 
the lower surface of the superiors which is here described 
and figured for furcata. 2. Satesi is described and fig- 
ured as having the abdomen with ‘‘a black dorsal band, 
commencing at the end of the third segment, and cover- 
ing the middle ot segments 4-9, and widened at the end 
of each segment to cover the entire width.’’ No such 
band exists on the present specimens, nor is it mentioned 
in Dr. Hagen’s description. 

Little weight is to be attached to the fact that the di- 
mensions of furcata are given as, length 4o mm., alar 
expanse 70 mm., and those of dafeszz as, length 48 mm., 
alar expanse 80 mm., or to the difference in the number 
of cross-veins. It is to be noted that although the generic 
characters of Cannacria include ‘‘abdomen as long as 
the hind wings,”’ the life-size figure of datesz7 shows the 
abdomen to be 34.5 mm. long, the hind wing 37 mm. 

Lastly, it is to be noted that Mr. Kirby has described 
a Cannacria Smith [Ann. Mag. N. H. (6) xiv, p. 266, 
Oct., 1894] from the West Indies. As is unfortunately 


552 CALIFORNIA ACADEMY OF SCIENCES. 


too often the case, Mr. Kirby omits all reference to struct- 
wral details from his description, and there is nothing to 
show that Smzthzr differs specifically from Batesz7.

M. collocata closely resembles JZ. semplicicollis ; for the 
males the only difference given is that in the latter the 
superior appendages are yellow, in co/locata black even 
in the teneral condition. The above males have the ap- 
pendages almost black, but in one or two the appear- 
ance strongly suggests that they may have been yellow 
when younger; no structural difference appears to exist 
to define them from semflicrcollis, but they have a trans- 
verse brown band on the anterior surface of the frons, 
wanting in the latter. 


ODONATA OF BAJA CALIFORNIA. 553 


For the female of co/locata, Hagen says (/. c. 1874) 
‘the appendages are yellowish, but the quadrangular 
black dorsal spot on the segments 4-10 [7. e. of semp/lice- 
collis| is wanting; only the sutures and margins of all 
the segments are black.’’ Ina female from Los Angeles, 
Cal., by Dr. A. Davidson, in the writer’s collection, there 
is only a narrow black stripe running along the mid-dorsal 
longitudinal carina of 3-9, but in the four females from 
San José del Cabo, October, 1893, this stripe is slightly 
but distinctly wider on the apical halves of 4-7, and be- 
comes an apical spot on 8-9; this difference between this 
form and the typical s¢mplrcicoll7s is therefore one of but 
slight degree. 

It seems doubtful if co//ocata can rank even as a va- 
riety. Abdomen ¢ 27-29.5, ? 26-28. Hind wing 6 30-

Distribution (of simplicicollis). United States east of 
the Rocky Mountains, Mexico (Matamoras, Huastec), 
West Indies, Bahamas; of co//ocata, according to Hagen, 
1875, Texas, Yellowstone, California— to which must 
now be added Baja California.

One male, California; the last four abdominal seg- 
ments are wanting; hind wing 30 mm., front wings with 
32 (right), 29 (left) antecubitals, the 5th and roth (right), 
6th and gth (left) thicker than the others; the first two 
yellow, lateral, thoracic stripes reach the coxe. The dark 
transverse band on the wings is not fully colored; its ex- 
tent exactly agrees with the description of a male variety 
from Porto Cabello, Venezuela, mentioned in the Mon. 
Calopt. p. 260, as follows: ‘‘the brown band does not 
extend as far as the pterostigma on the superiors, and 
ends at its origin on the inferiors; in a word the apical 
hyaline part of the wings is broader and equals half the 
breadth of the brown band.”’ 

Since this species is known only from Venezuela and 
Colombia, its discovery in California is of great interest, 
should no mistake have been made as regards the locality 
from which this individual came. Hitherto the genus 
Euthore has been regarded as exclusively South Amer- 
ican.

One female, California. 

Differs from Brauer’s description of 1866 by the ab- 
sence of a very fine transverse yellow line on the anterior 
edge of abdominal segments 3-6. 

Differs from de Selys’ description only as follows: 
costal, subcostal and median spaces pale yellow to the 
first antecubital and the median cross-vein; costa yellow 
exteriorly to beyond the pterostigma; pterostigma black- 
ish (Brauer says it is black), 4.5 mm. long; five median 
cross-veins on the front wings, two (other than that form- 
ing the internal triangle) on the hind wings, eight postcu- 
bitals on front wings (Brauer gives 8-9); the ‘*hamecon

en forme de pli’’ on each side of the vulvar lamina not 
distinguishable, perhaps owing to the compression of the 
apical half of the abdomen. Abdomen 58, hind wing 53. 

This species'has hitherto only been known from China 
and Japan; its occurrence in California, should the local- 
ity bercorrect, is very interesting... Where seems to be no 
doubt of its being this species, the correspondence with 
the descriptions is so exact and the differences above 


given are not of specific value.

TWO SPECIES OF AQUILEGIA FROM THE UPPER 
SONORAN ZONE OF COLORADO AND UTAH. 


BY ALICE EASTWOOD. 


With Plates xviii and xix. 


AQUILEGIA MICRANTHA n. sp. Perennial; lower part 
of stem and leaves unknown; upper part villous with 
white hairs, viscid especially between the rounded irreg- 
ular ribs; leaves triternate: petioles equaling or surpass- 
ing in length the rest of the leaf, very viscid and clothed 
with long white hairs which are most numerous on the 
edge, strongly ribbed, dilated at base, spreading into 
sheathing membranous undulate, stipule-like margins, 
which are very viscid and villous; upper leaves almost 
sessile; upper petiolules longer than the two lateral 
and with larger leaflets; leaflets cuneate, 3-cleft or 
divided irregularly, with rounded obtuse or acute lobes, 
somewhat revolute on the margins; under side more vis- 
cid and hairy than the upper and with veins more distinct; 
flower about 2 cm. across, cream-white; sepals 10 mm. 
long, 4 mm. broad with a short broad claw, ovate, acute, 
somewhat hairy and viscid on the back; petals with 
spurs straight or curved, varying in length, upper part 
truncate or slightly retuse about 7 mm. long and 5 mm. 
broad; stamens numerous with filaments of different 
lengths; anthers about 1 mm. long; united staminodia 
surpassing the petals; styles surpassing the stamens, 
curved at apex; fruit of four or five follicles about 15 mm. 
long without the styles which are about the same length, 
with strong veins branching downwards from the mid- 
nerve, somewhat viscid and villous; seeds glossy black. 

The type is fragmentary and was sent to me by Mr. 
Alfred Wetherill of Mancos, Colorado. He reports it as 
abundant in the canons of the San Juan River in south- 

2p SeR., VoL. IV. ( 37 ) March 19, 1895.

eastern Utah, growing under shady cliffs where the rocks 
and soil are always moist from the oozing alkaline water. 
It was, according to Mr. Wetherill, so similar in manner 
of growth and general appearance to Aguzlegia ecalcarata 
that at first he thought it that species. 

Collected near Bluff City, southeastern Utah, July, 


1894. 


AQUILEGIA ECALCARATA Eastwood, Zoe ii, 226, Zoe 
iv, 3,259. This Aquilegia from one of the cafions of the 
Mancos River in southwestern Colorado, appears closely 
related to A. micrantha, and it has seemed to me desira- 
ble to figure it on the same plate, so as to show the two 
together. It resembles Isopyrum in the general outline 
of the flowers and might be looked upon as a connecting 
link between that genus and Aquilegia. However, a close 
inspection discovers it to be a true Aquilegia with abor- 
tive spurs, and, upon comparison with A. mzcrantha, it 
seems most closely related to that species; but whether its 
degenerate descendant or less specialized progenitor or 
perhaps even a starved, cave-dwelling form, cannot be 
now settled. The fact, too, that these two Columbines are 
in the same river system, the same region, and have been 
found in no other place, strengthens the theory of their 
close relationship. A. eca/carata has been seen in but one 
niche-like cavern, where the sun never comes and where 
the supply of water is so slight during the hot dry summer 
that it is forced to cling close to the damp rocks, even 
climbing up the sides of the cave with its slender thread- 
like stems. Its home is at the head of Johnston Canon, 
a southern branch of the Mancos Canon. A. mzcrantha, 
according to Mr. Wetherill, is abundant and widely dis- 
tributed through the canons of the lower San Juan River, 
of which the Mancos River is a tributary. 


TWO SPECIES OF AQUILEGIA. 561 


According to the Index Kewensis, A. ecalcarata is a 
synonym of A. vulgaris L. As I am not in sympathy 
with the movement that is producing such chaos in nom- 
enclature and do not care to become a name changer my- 
self, I here leave it with the name under which it has 
been described and add a general description, so as to 
bring together all that is known about it. 


AQUILEGIA ECALCARATA Eastwood. Perennial, from 
a long woody tap-root, stems numerous from a tufted 
base which is covered with the brown sheaths of dead 
leaves, glaucous, slightly viscid, above angled, below 
ribbed, above sparingly villous and more viscid; leaves 
on long slender petioles which are dilated at base into 
stipule-like sheaths, triternate with filiform petiolules; 
leaflets cuneate, irregularly lobed or divided with lobes 
obtuse, often the upper one acute, paler on the under 
side, thin and wavy; upper leaves with broad sheathing 
petioles; flowers numerous, panicled, on long slender 
pedicels; upper bracts few, linear-lanceolate 5 mm. 
long; lower bracts similar to the upper leaves but small- 
er; flowers 2 cm. broad, pink or white, of delicate text- 
ure, with a strong sweet perfume; sepals ovate-lanceo- 
late, with a short claw which is thickened in the middle 
by the veins which spread out on the lamina, slightly 
viscid and villous on the back, ciliate with rather coarse 
hairs; petals 12 mm. long and about 2 mm. broad, ter- 
minating at base in a small sac-like spur, emarginate, cil- 
iate and veiny; stamens numerous, the filaments nearly 
equal, hardly surpassing the petals; staminodia united, 
shorter than the petals, ovary somewhat viscid and hairy, 
styles smooth, curved at the apex, hardly surpassing the 
stamens; fruit and seeds similar to A. mzcrantha. 

This was first described from a fragmentary specimen 
sent me by Mr. Wetherill, who found it June, 1891. 


562 CALIFORNIA ACADEMY OF SCIENCES. 


Professor Marcus E. Jones redescribed it in his Revision 
of Aquilegia, Zoe iv, 3, 259, making the section Pseuda- 
quilegia to contain it. The characteristics of this section 
will have to be modified so as to also include A. mzcrantha, 
and I suggest the following: 

Pseudaquilegia—leaves triternate, spurs irregular or 
abortive, flowers small. 


In the early part of September, 1892, I visited the type 
locality, which is in the Ute Reservation of Colorado, 
about twenty-five miles from Mancos, and collected 
fruiting specimens which were distributed to the principal 
herbariums of this country. Roots and seeds were also 
obtained; but of all that was distributed the only survivors 
are ‘in the garden of -Mr. J. 1. Henderson of Denver; 
Colo., where they have bloomed during the past two 
summers.

CRYPTOPHRYS PUBESCENS sp. nov. 


Carapax subpentagonal, convex, the median and car- 
diac regions tumid and separated from the hepatic and 
branchial by a sulcus; there is a slight depression be- 
tween the gastric and cardiac regions and another behind 
the latter. Front slightly projecting and notched in the 
center. Antero-lateral margins not defined by a ridge; 
the sides of the carapax are broadly rounded. Orbits 
nearly circular; eye peduncles very short and stout. An- 
tennules transverse; the antennulary fossettes communi- 
cate with each other beneath the front. Antenne shorter 
than the width of the front. Buccal area much broader 


than long, convex in front, concave behind. The isch-

ium of the maxillipeds is rudimentary; the meros is large 
and curved, the distal margin oblique; palp two-jointed, 
the last joint oblong. Owing to the peculiar shape of the 
buccal area the maxillipeds are very oblique, the distal 
margins of the meros joints are parallel and longitudinal, 
leaving between them a nearly square area which is filled 


with the palpi. Chelipeds moderate, exceeding the first

Locality: Muleje Bay, Gulf of California. 

One specimen from a vial containing a specimen of 
Pinnotheres margarita Smith, which it much resembles 
in form and pubescence. This species is very readily 
distinguished from C’. concharum Rath. M. by the shorter, 
stouter, and less compressed ambulatory legs and the 
presence of the longitudinal sulci on the carapax, which 
are entirely absent in that species. 


PSEUDOPINNIXA gen. nov. 


Carapax much broader than long, the anterior margin 
nearly straight, the frontal process deflexed. Orbits 
nearly round. Antennules obliquely or transversely pli- 
cated, the fossettes communicating with each other beneath 
the front. Buccal area small, subtriangular. External 
maxillipeds with the ischium rudimentary, the meros large, 
triangular; palp three-jointed, the terminal joint joined to 
the tip of the preceding one. First pair of ambulatory 
legs the largest, the others successively diminishing in

PSEUDOPINNIXA NITIDA (Lock). 
Pinnixa? nitida Lockington, Proc. Cal. Acad. Sci. vii, p. 155. 

Carapax smooth, shining, a little over twice as broad 
as long, longitudinally convex, transversely plane, the 
sides evenly rounded; the anterior margin is straight; 
the front is broadly triangular, short, much deflexed, not 
at all projecting, and having a groove behind the margin. 
Orbits nearly as wide as long, the inner hiatus wide and 
partly filled by the base of the very minute antenne. 
Antennules obliquely (nearly transversely ) plicated. 
Epistoma very short, curved. Buccal area broadly sub- 
triangular, rounded in front, the posterior portion covered 
by a projection of the sternum. External maxillipeds 
subtriangular, the ischium rudimentary; the meros is 
large and has the portion nearer the mouth bent inward 
at a considerable angle to the outer face; the first joint 
of the palp short and stout, the second oblong, the third 
very small. Chelipeds rather short, moderately stout, 
smooth; the meros is not much longer than the carpus; 
hand a little compressed, the palm thickened and pro- 
vided on the outer surface with two longitudinal lines of 
short cilia; fingers scarcely as long as the palm, tooth- 
less, and hooked at the tip; on the upper surface of the 
movable finger is a line of cilia which is roughened by 
minute projections. Ambulatory legs ciliated on the 
margins; the first pair is stouter and a little longer than 
the others and has the anterior surface of the meros smooth 
and concave where it rubs against the chelipeds; the next 
two joints are stout; the tarsus is short, subcylindrical 
and curved, and tapers rapidly to an acute, corneous tip. 
The third pair of ambulatory legs is a little shorter than 
the second; both are more compressed than the first pair ; 
the tarsi are similar in all three pairs; fourth pair very 
short, not reaching the distal end of the meros of the pre- 


WEST AMERICAN CRUSTACEA. 567 


ceding pair; the penultimate joint is relatively wider than 
in the preceding pairs; tarsus similar to the others. Ab- 
domen of the female rather small, not covering one-half 
the sternal area, and seven-jointed; the segments grad- 
ually increase in width from the first to the third, then 
decrease rapidly in width to the last one, which is longer 
than the others, subtriangular in shape, but with a rounded 
apex. The sides of the posterior portion of the abdomen 
are concave. 

Lockington, in his description of this specimen, says 
that the ‘‘color in spirits’’ is ‘‘ bright orange,’’ and the 
specimen still retains a decided orange tinge. 

Length of carapax, 5--mm.; width, 11 mm. 

Locality: Angeles Bay, Gulf of California. 

This species, together with the one here described as 
Pinnixa tomentosa, were both described by Lockington 
as Pinnixa nitida under the erroneous impression that 
they were the male and female of the same species. He 
evidently had some misgivings about their specific iden- 
tity, for he says: ‘‘A single specimen of each of the two 
crustaceans just described was collected on the same day 
at the same locality—namely, Angeles Bay, Gulf of Cal- 
ifornia—and the two were placed by the collector (Mr. 
WW. Ji--Bisher) in’ the same vials -Had it not been for 
this, I should certainly have never linked together two 
specimens so distinct in the relative proportions of the 
limbs themselves, as well as of the joints of those limbs; 


one covered in many places with an abundant pubescence, 
the other smooth and shining above and below. ‘The 
proportions of the ambulatory limbs of the female agree 
with the genus Pzxuixa, but in the male the increase of 
size is transferred to the second pair. Should these crus- 
tacea prove to be distinct the female should be Prxnixa 
tomentosa, while the male must be placed in some other 


568 CALIFORNIA ACADEMY OF SCIENCES. 


genus.’’ An examination of these very specimens which 
are preserved in the collection of the California Academy 
of Sciences and from which our descriptions and figures 
are taken, has convinced us that they, indeed, belong to 
different genera. Moreover, the specimen Lockington 
considered to be a male is not a male at all, as an exam- 
ination of the vulve and the appendages on the under 
side of the abdomen unmistakably shows. The abdomen 
is small for a female of this group, and Lockington prob- 
ably did not lift it up and examine the ventral side, but 
concluded that the specimen was a male from the small 
size of that organ. As Lockington named the female P. 
tomentosa, in case it should prove distinct, this name should 
stand, since the supposed male belongs to a different 
genus. 


PINNIXA TOMENTOSA Lock. 
Pinnixa tomentosa Lockington, Proc. Cal. Acad. Sci. vii, p. 156. 


Carapax very nearly twice as broad as long, smooth, 
and rounding off towards all the margins; the upper sur- 
face is somewhat flattened and there is a shallow depres- 
sion behind the gastric region behind which the carapax 
is convex but not ridged. Antero-lateral margin broadly 
rounded and marked by a ridge only towards the outer 
extremity. Front short, with a longitudinal groove in the 
middle and a slight depression behind the transverse an- 
terior margin. The distance between the orbits is about 
one-fourth the breadth of the carapax. Orbits transverse. 
Antennules obliquely plicated. Epistoma very short. Ex- 
ternal maxillipeds nearly longitudinal; meros large, sub- 
quadrate, the distal portion of the outer margin convex; 
the penultimate joint of the palp is moderately narrow 
and tapers from the base to a rounded extremity; the 
third joint is spatulate and joined near the base of the

preceding one and projects a short distance beyond it. 
Chelipeds scarcely as long as the fourth pair; the meros 
trigonal, hand oblong, compressed, longer than all the 
preceding joints combined; fingers but little more than 
one-half the length of the palm: the pollex is wide but 
abruptly narrowed near the hooked tip; dactyl curved, 
toothless, subuncinate at the apex. Ambulatory legs 
compressed; the first pair shorter and more slender than 
the second; the tarsus is rather slender and about as 
long as the propodus. The second pair stands about in- 
termediate in size between the first and third pairs; the 
tarsus is not quite as long as the propodus and is relatively 
stouter than that of the first pair. Third pair not greatly 
exceeding the second in length, the tarsus much shorter 
than the propodus and much stouter than the tarsus of 
the second pair; there is no flange or groove on the pos- 
terior margin of the meros. Fourth pair shorter and rel- 
atively stouter than the first ambulatory legs but reaching 
beyond the distal end of the meros of the third pair; tar- 
sus short and stout. The fourth pair closely resembles 
the third in most points except size. Abdomen of female 
transversely elliptical and covering the entire sternal sur- 
face. The carapax-and legs were covered with a very 
short pubescence. 
Length of carapax 7.5 mm.; breadth, I4 mm. 
Locality: Angeles Bay, Gulf of California. 


PINNIXA TUBICOLA sp. nov. 


General form subcylindrical. Carapax about two and 
one-half times as broad as long, strongly curved down- 
wards towards the anterior margin and sides. There isa 
shallow, transverse depression behind the gastric region 
behind which is a convex (not crested), transverse intu- 
mescence, from which the carapax curves sharply down-

wards to the broad, slightly concave posterior margin. 
Front short, deflexed, and not projecting beyond the gen- 
eral contour of the carapax; it is furnished with a short 
median groove, but the transverse groove behind the an- 
terior margin, which is so conspicuous in P. /ongipes, is 
shghtly or not at all marked. Antero-lateral margins 
marked by a ridge along their distal portion which inter- 
sects the postero-lateral margin at somewhere near a right 
angle. Mavillipeds pubescent; the postero-internal angle 
of the meros is curved inward, and the distal portion of 
the outer margin is convex; penultimate joint of the palp 
oblong-ovate; the last joint is spatulate and is joined near 
the base of, and extends considerably beyond, the pre- 
ceding joint; exopod rather broad, and bearing a rounded 
projection near the middle of the outer side, beyond which 
the margin is concave. Chelipeds rather small, shorter 
than the second ambulatory legs, meros much larger than 
the carpus; hand oblong, compressed, longer than the 
combined lengths of all the preceding joints; fingers a 
little over one-half the length of the palm; the tips of the 
fingers are hooked and their inner margins meet when 
they are closed. The first pair of ambulatory legs is 
slender and furnished with rather slender tarsi which are 
about equal in length to the propodi. The second pair is 
much longer and stouter than the first and have relatively 
somewhat stouter tarsi which are a little shorter than the 
propodal joints. The third pair of ambulatory legs is 
stouter and a little longer than the second and are furnished 
with shorter and stouter tarsi which are conspicuously 
shorter than the preceding joint. The fourth pair is similar 
in character to the third but rarely extends beyond the dis- 
tal end ot the meros of the preceding pair. Abdomen of 
female transversely elliptical, the first joint very short, 
the second about one-half as long as the third. Abdo-

area on either side and tapering from the third joint, be- 
yond which the sides are somewhat concave, to the rounded 
tip; the first and second segments are short and subequal; 
the four succeeding segments are subequal in length; 
the last segment is much broader than long and evenly 
rounded. 

Length of carapax, 4 mm.; breadth, 10 mm. 

This species is usually found in the leathery tubes of 
annelids. The legs and portions of the Carapax are Cov- 
ered with a short pubescence, but the upper surface of 
the carapax is usually naked and often marbled with 
patches of color. There are often two ridges which ex- 
tend backward from near the middle of the antero-lateral 
margins to within a short distance of the posterior margin 
of the carapax. In some specimens these ridges are quite 
distinct but in others they are scarcely visible. 

Numerous specimens from Trinidad, Cape Mendocino 
and Bodega Bay. 

This species is closely allied to P. tomentosa L., but 
differs from it in the relatively greater width of the car- 
apax which is naked and furnished with much larger 
punctations, in the much smaller chelipeds, in the more 
slender ambulatory legs with relatively longer and more 
slender tarsi. In P. tomentosa there is a curved line of 
small pits behind the gastric region, a character which is 
absent in our species. 


PINNIXA LITTORALIS sp. nov. 


Carapax naked, flattened above; behind the median 
region is a transverse depression followed by a transverse 
intumescence behind which the carapax curves strongly 
downwards to the slightly concave posterior margin. The 
front is not strongly depressed and projects beyond the

general outline of the carapax; it is anteriorly truncated 
and furnished with a median groove but has no transverse 
groove behind the anterior margin. Antero-lateral mar- 
gin marked by a ridge which begins near the orbit and 
runs outward and slightly backward to the side of the 
carapax where it curves abruptly backwards, becoming 
faintly marked towards its distal end. Maxillipeds nearly 
naked, similar in shape to those of P. ¢ubicola; the last 
two joints of the palp are more or less grooved on the 
outer surface and the penultimate joint extends only a 
short distance beyond the preceding one. Chelipeds 
rather large, smooth, carpus much shorter than the meros; 
hand large, compressed, oblong, but widening slightly 
distally, and exceeding in length all the preceding joints 
combined; thumb short, edentulous, directed obliquely 
downwards and furnished at the tip with a notch into 
which the point of the movable finger closes; the mov- 
able finger is much longer than the thumb, edentulous, 
and curved so that when it is closed against the thumb a 
large rounded space is left between them. Ambulatory 
legs almost entirely naked, more slender than in 2... 02- 
cola; the first pair is considerably shorter than the second 
which is but little shorter than the third; the fourth pair 
may extend a little beyond the meros of the third; the 
tarsi are in all the legs little, if any, over one-half the 
length of the propodi and are curved at the corneous 
tips. Abdomen of male tapering evenly from the base to 
the tip; the last joint is subtriangular, about as broad as 
long, the apex rounded; the preceding joint has the sides 
concave but the sides of the remaining joints are straight; 
the first and second joints are subequal and together about 
as long as the third; the remaining segments subequal in 
length.

Carapax considerably more than twice as broad as long, 
smooth, somewhat flattened above and furnished with a 
transverse depression behind the gastric region. Front 
slightly projecting and furnished with a groove just be- 
hind and parallel with the transverse anterior margin; 
there is also a short longitudinal median groove which 
becomes deeper toward the anterior margin of the frontal 
process. Antero-lateral margin rounded, usually marked 
by a more or less evident ridge, and meeting the concave 
postero-lateral margin at an acute angle. Posterior mar- 
gin long and straight. The lower edge of the anterior 
margin of the carapax (not the antero-lateral margin 
proper) is furnished with long hairs. There is a ridge 
which runs from the outer end of the orbit downwards 
and outwards to the edge of the carapax. Orbits oblong, 
transverse. Antennule obliquely plicated. Mavwillipeds 
oblique, furnished with long hairs, the meros large, nearly 
twice as long as broad, the outer margin convex; the pen- 
ultimate joint is subovate; the last joint is broadly spat- 
ulate, joined near the base of and slightly exceeding the 
preceding one; the expod has the edges parallel and the 
outer distal angle concave. Chelipeds small, short, hairy;

hands oblong, compressed; fingers shorter than the palm. 
The first two pairs of ambulatory legs are slender (the 
second somewhat larger than the first) and furnished with 
slender, nearly straight tarsi which are about equal to the 
propodal joints. The fourth pair of pereopods is very 
large, considerably longer than the breadth of the carapax 
and about two-thirds as wide as the carapax is long; on 
the posterior margin of the meros is a kind of flange above 
which is a shallow groove; tarsus shorter than the pro- 
podus, stout, curved. ‘The last pair is small and propor- 
tionately stouter than the anterior ambulatory legs, and 
has the edges densely hairy. This pair scarcely reaches 
beyond the middle of the meros of the preceding pair; 
the carpus and propodus are about as broad as long, the 
tarsus short and stout, similar to that of the fourth pair. 
All of the legs are compressed and more or less hairy. 
Abdomen of female transversely elliptical and seven- 
jointed. Abdomen of male seven- jointed, the first two 
joints shorter than the others, the last joint broader than 
long and rounded at the tip. The male abdomen tapers - 
evenly from the base which is about one-third the width 
of the thoracic sternum to the last joint. 

This crab is remarkable for its great width and the 
great development of the fourth pereopods. It lives in 
tube of a species of annelid. 

Lockington in his description of this species states that 
the third joint of the external maxillipeds is very small, 
the second stout and large. He probably mistook the 
meros for the second joint, for the latter is rudimentary 
or absent in the subfamily to which Prxxzxa belongs.

This genus is founded on the species described as 
Dermaturus hispidus by Stimpson (in Ann. N. Y. Lyc.

Brandt in the presence of spines on the body and legs, 
and in the large, spiny, prolongation on the outer side of 
the second joint of the antenne, which is entirely absent 
in that genus.

HipPOLYTE CALIFORNIENSIS Sp. nov. 


A long, slender species. Rostrum slightly longer than 
the carapax, slender, nearly horizontal, very slightly up- 
turned, tapering uniformly to the tip; on the upper mar- 
gin it is armed with three to five low, acute teeth, the 
points of which are directed forwards and slightly up- 
wards; on the lower margin there are four or five similar 
teeth, the last one being so near the tip of the rostrum as 
to give it the appearance of being bifid. The base of the 
rostrum is rounded above and there is a spine on either 
side of it above and behind the ocular peduncles. On 
the upper part of the anterior margin of the carapax is a 
tooth below which is an acute spine. There is a convex- 
ity but no spine at the lower angle of the margin, but 
there is a prominent spine within the margin behind the 
base of the second antenne. 

Peduncle of the first antennz about one-half as long as 
the rostrum, the spine at the outer side of the base flat- 
tened and about two-thirds as long as the first joint which 
is much depressed and has the inferior inner margin pro-

reaching the tip of the rostrum, much shorter than the 
slender inner flagellum, the last few joints much more

the scale is narrow and nearly reaches the tip of the ros- 
trum in some Cases. 

The apical plate (psalistoma) of the mandibles is very 
slender, flexible, and bears five or six teeth at the tip. 

The third maxillipeds are slender and short, not reach- 
ing the tip of the peduncle of the second antenne; the

second joint has a laminate expansion on the inner side; 
the third joint equals or somewhat exceeds the last two 
and has the inner margin concave; the last joint is about 
twice the length of the preceding one and armed around 
the tip with nine to eleven spines. 

The first pereopods are exceedingly short but stouter 
than the succeeding pairs; the carpus is excavated so as 
to receive the rounded lobe of the hand; the hand is 
broadened and thickened at the base where it is produced 
backwards into a prominent lobe; fingers excavated, their 
tips furnished with several small spines. Second pereo- 
pods slender, much longer than the first pair, but shorter 
than the third, the carpus three-jointed (the first joint 
the longest) ; hand slender, not half as long as the carpus, 
fingers excavated within. The last three pairs of pereo- 
pods decrease successively in length. 

Abdomen slender, not at all crested or carinated; the 
postero-lateral angles of all of the segments except the 
last one rounded. ‘Telson truncated and spinulous at the 
tip and furnished with a few spinules near the lateral 
margin. 

Length of specimen, 38 mm. 

Color, green. 

Taken in Bodega Bay, July, 1894. The females were 
loaded with ova. 


Family MIERSIIDZ. 
MIERSIA PACIFICA sp. nov. 


Rostrum about as long as the carapax, slender, taper- 
ing uniformly to the tip; there may be either one or two 
spines on the upper side and on the under side the num- 
ber of spines varied in the specimens examined from five 
to nine. ‘The spines are less distant from each other near 
the base of the rostrum but there may be two close to-

gether near the tip or but one spine so situated that 
the rostrum may appear either trifid or bifid. The car- 
apax is not crested in front. There is a supra-orbital 
spine and two spines on the anterior margin of the car- 
apax the upper one of which is situated just below a short 
suborbital tooth. The antennules are provided with two 
long flagella which usually do not differ markedly in 
length; the outer flagellum presents a tolerably well 
marked division into a basal portion and a more slender 
and somewhat longer distal part. The first joint of the 
antennular peduncle is transversely hollowed out and 
furnished with an external spine which usually extends a 
little beyond the tip. The antennal scale reaches about 
to the tip of the rostrum and the flagella often exceed the 
length of the body. The mandibles are devoid of a palp 
and are divided (but not deeply so) into a molar process 
and a broad, thin, dentate cutting edge. 

The maxillipeds do not reach the tips of the antennal 
scales but generally exceed: the tips of the peduncles; 
the exopod may reach beyond the tip of the penultimate 
joint and always exceeds the third one; the last joint is 
longer than the preceding one and is furnished with a 
row of spines on the distal third of the inner margin. 

All of the pereopods, except the last pair, are furnished 
with exopods. The first pair is short, the carpus short, 
distally widened; hand oblong, not very much broader 
than thick; at the proximal end is a rounded process 
which fits into a concavity in the distal end of the carpus; 
fingers nearly as long as the palm, excavated within, the 
tips rounded and furnished with a dense tuft of sete. 
Second pereopods longer than the first but shorter than 
the third; carpus not annulated, hand slender, strongly 
incurved;. fingers with sete at the tip. The three fol- 
lowing pairs of pereopods are subequal; the tarsi are not

one-third as long as the preceding joints, the lower mar- 
gins spinulous. Telson tapering to a truncated or broadly 
rounded spinulous extremity. |

Family PALASMONIDZ. 
PAL@MON RITTERI sp. nov. 


Carapax shorter than one-half the length of the abdo- 
men, the anterior half or third crested. There is a spine 
beneath the angular suborbital projection of the anterior 
margin of the carapax, and on the margin below this is 
another situated behind the base of the second antenne 
and above the rounded antero-inferior angle. No hepatic 
spine. Rostrum a little longer than the carapax, and ta- 
pering tolerably evenly from the widest portion (which is 
about one-fourth as wide as the rostrum is long) to an 
acute tip. The upper margin is armed with seven or 
eight teeth of which the posterior one is situated on the 
gastric region and the anterior one (often small) some 
distance from the tip. On the inferior margin of the ros- 
trum are three teeth, the anterior one rather remote from 
the tip. Ocular peduncles short and stout; the ocellus 
lies between the cornea and the stalk. The first basal 
joint of the first antenne is about twice as long as broad; 
the spine on the outer side reaching about to the middle 
of the joint; there is a small tooth at the antero-external 
angle. The next two joints are short and cylindrical; 
the inner flagellum is slender and rather long. Outer 
flagellum flattened and entire to a distance about equal to 
the length of the third joint of the peduncle where it di- 
vides into a slender, external portion which is longer than 
the internal flagellum and a short and closely annulated 
portion which is not greatly longer or shorter than the pe-

duncle. The second antenne are furnished with an ob- 
long scale which is shorter than the rostrum; the flagel- 
lum is very slender and longer than the body. Mandibles 
with an oblong molar tubercle and a curved, somewhat 
tapering, dentate cutting edge and a three-jointed palp 
which is about as long as the cutting edge. Third max- 
illipeds reaching about to the tip of the peduncle of the 
second antenne, and furnished with a slender exopod 
which is nearly or quite as long as the antepenultimate 
joint; terminal joint about three-fourths as long as the 
preceding one. First pair of chelipeds slender and not 
reaching beyond the tip of the rostrum; the carpus is 
very little longer than the preceding joint and bears no 
spine; hand but little over one-half the length of the car- 
pus, slender, linear, the fingers straight and about as long 
as the palm. The second pair very little longer than the 
first and like them do not extend beyond the tip of the 
rostrum; the carpus is not one-half as long as the pre- 
ceding joint and is nearly as long as the palm of the pro- 
podus. Hand slender, linear, slightly bent, the fingers 
nearly as long as the palm, nearly straight, the tips hooked. 
The three remaining pairs of pereopods are subequal in 
length and a little longer than the chelipeds; propodi 
spinulous on the posterior margin, about twice the length 
of the carpi; tarsi slender, curved, acute. 

Telson rounded above, longer than the preceding joint 
and furnished with two or three pairs of aculei near the 
margin and several sete at the tip. 

Length, 4.5 cm. 

Taken by Dr. Ritter at San Diego, July, 1891. Four 
specimens. 

This species is near Pa/emon squilla, serratus and es- 
pecially afin’s M. Edw. From the last named species it 
differs in the broader rostrum, the much shorter second

entirely separated from the cornea as described and fig- 
ured by Spence Bate (Challenger Reports xxiv, p. 782, 
pl. cxxviii), nor situated in the cornea as in P. sguzdla, 
but is between the two.

The three specimens we have of Penzus, one from south- 
ern California and two from San Francisco Bay, we 
refer without much doubt to the above species which is 
fully described and figured by Spence Bate in the Chal- 
lenger Reports. It is probable that the species from the 
west coast of Nicaragua, described by Kingsley as P. 
brevirostris (Proc. Phil. Ac. Sci. 1878, p. 98) and subse- 
quently referred by him to P. Braziliensis (1. c. 1879), 
should have been referred to P. canaliculatus, as the spec- 
imens we have agree very well with Kingsley’s descrip- 
tion. The two species are very closely allied and it is 
probable that they are mere geographical varieties. The 
specimens of P. Braziliensis we have seen have longer 
and more slender legs than our specimens, but the other 
differences are slight. P. canaliculatus was described 
from Japan and Australia, and varies considerably in the 
different localities in which it is found. P. Braziliensis 
is likewise very extensively distributed over both shores 
of the Atlantic Ocean.

Suborder SCHIZOPODA. 
Family MYSIDA. 
CALLOMYSIS gen. nov. 


Carapax having a deep posterior sinus which leaves a 
portion of the pereon uncovered. Rostrum short. Eyes 
normal. Antennules with a setose lobe at the base of the 
outer flagellum; the sensory appendage usually found in 
the males of schizopods is absent. Antennal scale ob- 
long, truncated, and ciliated on the inner and distal mar- 
gins; outer margin naked and terminating in a spine. 
The gnathopods resemble the maxillipeds but have a 
larger endopod. The distal portion of the thoracic legs 
is divided into numerous articulations. Pleopods in the 
female rudimentary and biramous, the outer ramus smaller 
than the inner one. In the male the pleopods are small, 
biramous, the outer ramus of the third pair elongated; 
the fourth and fifth pairs short. Inner ramus of the uro- 
pods furnished with the usual auditory apparatus. Tel- 
son well developed, the margins spinous, the tip provided 
with an emargination in which are situated several spines. 
Marsupial pouch formed by two pairs of large lamelle 
and a rudimentary third pair. 


CALLOMYSIS MACULATA Sp. nov. 


General form rather slender. Carapax not one-half as 
long as the abdomen, with broadly rounded antero-lateral 
and postero-lateral angles. Rostrum short, subtriangu- 
lar. Abdomen subcylindrical, slightly tapering, the pos- 
terior segment the longest. Ocular peduncles pyriform; 
cornea subhemispherical. The antennular peduncles are 
moderately stout, the first and third joints oblong (the 
third shorter than the first), the second joint a little 
broader than long; the outer flagellum is considerably 
longer than the inner one but shorter than the body and

bears a setose lobe at the base. The peduncles of the an- 
tenne are shorter than those of the antennules and have the 
last joint about as broad as long; the scale is shorter than 
the peduncle and extends as far forward as the tip of the 
penultimate joint of the antennules; the flagellum seldom 
exceeds one-half the length of the body. The mandibles 
have a molar tubercle and a dentate cutting edge; the 
second joint of the long palp is arcuate and longer and 
much broader than the third, which is slender and tapers 
to a subacute tip. First maxilla normal. Second max- 
‘illae with three oblong masticatory lobes and a subovate 
exognath which bears 13-16 marginal sete; second joint 
of palp oblong-ovate. 

Maxillipeds with broad basal joints; the exopod much 
longer than the endopod, the terminal portion divided 
into numerous (fifteen in specimens) articulations; the 
terminal joint of the endopod is rounded, thickly setose 
and devoid of a claw. The gnathopods closely resemble 
the maxillipeds but the endopod is larger and the termi- 
nal joint is subacute. The following pair of appendages 
has the endopods longer than the exopods; the terminal 
portion is longer than the preceding joint and divided, in 
several specimens examined, into ten to thirteen setifer- 
ous articulations. The remaining thoracic legs are simi- 
lar to the pair of appendages just described. 

Pleopods rudimentary in the female, mostly shorter 
than the width of the abdominal segments to which they 
are joined and bearing a minute outer branch. ‘The first 
pair is longer than the others and bears two short, sub- 
equal rami at the tip of the relatively long peduncle. 

In the male the first pleopods have an oval peduncle 
which is furnished with plumose setz along the outer 
margin; the outer ramus is longer than the peduncle and 
is divided into several setiferous articulations; the inner 


584 CALIFORNIA ACADEMY OF SCIENCES. 

ramus consists of a single, small, oblong joint which is 
shorter than the peduncle and bears several plumose sete. 
The second pleopods are a little longer than the first pair, 
the inner ramus is shorter than the outer but like it di- 
vided into several joints. In the third pair the inner ra- 
mus is short but the outer one is long and slender and 
reaches back further than the penultimate abdominal seg- 
ment; the terminal joints are much elongated but towards 
the base the annulations become closer. The fourth and 
fifth pleopods are subequal and a little shorter than the 
first two pairs; the inner rami are shorter than the outer 
and like them are divided into several setose articulations. 

Uropods subequal in length and equaling or a little 
exceeding the telson. The inner one is a little narrower 
than the outer and subacute; the outer one rounded at 
the tip. Both are fringed on both sides with plumose 
sete. Telson subrectangular, between two and three 
times as long as broad, each outer margin furnished with 
eight spines of which the terminal one is the largest. In 
the emargination at the apex are 10-13 slender spines 
which increase in length from the innermost one to the 
second or third from the outermost. 

Color nearly transparent, with large black spots from 
which radiate numerous irregularly branching streaks. 
These spots do not occur on the carapax: there is 
usually one on each side of each abdominal segment and 
two on the anterior plate of the marsupial pouch. There 
is a spot on the telson and another partly on the telson 
and partly on the last abdominal segment. 

Length, 15 mm. 

Taken at Trinidad from a sandy beach in which they 
burrow, June, 1894. The females had their marsupial 
pouches filled with eggs or larve.

Lepipurus LEMMON! sp. nov. 


Carapax oval in outline; the sides are furnished with 
numerous small teeth which begin near the rounded an- 
tero-lateral angles and become longer, more slender and 
more closely set towards the postero-lateral angles; the 
dorsal crest of the carapax is furnished with a variable 
number of unequally spaced spine-teeth which varied in 
the specimens examined from ten to fifteen. The poste- 
rior emargination of the carapax is furnished with from 
five to seven teeth (counting the terminal ones), the 
number of teeth on the two sides being often different in 
the same individual. The postero-lateral angles are nearly 
right angles. The eyes are usually reniform and their 
anterior ends lie near together. The inter-ocular tubercle 
is round, small, considerably elevated and located consid- 
erably behind the posterior margins of the eyes. An- 
tennez short, simple, smooth. Second antenneze absent. 
Labrum nearly square but with rounded angles. The 
maxillz are deeply divided into an anterior lobe which is 
ciliated and a larger posterior lobe which is spinulous 
along its inner edge. The first pair of legs are of mod- 
erate length, none of the endites in the specimens exam- 
ined reaching further back than the postero-lateral angles 
of the carapax; the second endite reaches but little be- 
yond the base of the third which is considerably longer 
than the fourth; the fifth forms a short, pointed, ciliated 
scale; gill triangular. 

In the second pair the second endite scarcely reaches 
the base of the terminal ones, the third is about two-thirds 
as long as the fourth; the fifth is about as long as the 
fourth, acutely pointed and finely pectinated on the inner

edge. The eleventh pair of legs in the female are sim- 
ilar to those of ZL. glacialis. There are usually about 
five of the terminal abdominal segments exposed and 
nearly an equal number (sometimes less) which are de- 
void of appendages on the ventral side. The number of 
spines on the penultimate abdominal segment is never far 
from twelve. On the upper side of the last segment is a 
small, spinulous prominence in front of the base of each 
stylet. The telson is rather long, oblong, somewhat wider 
in the middle, and may be rounded, truncated (obliquely 
so in some specimens), or, in some cases, bilobed; 
the margins are furnished with several minute spinules, 
and there are, in most of the specimens, two spines in 
the middle line at the base, but in one specimen there 
were three spines at the base and a small one near the 
middle. Except where the teeth are situated, there is no 
median ridge or carina, as in Z. Couszz. The caudal 
stylets are minutely spinulous and are longer than the 
body including the telson. 

Length, 28 mm. 

Color (in alcohol), greenish. . 

Four females and one male loaned by Mr. Rivers. 

Collected at Honey Lake, by J. S. Lemmons. 

This is the fourth species of Lepidurus that has been 
described from North America and the first member of 
the Apodide reported from the Pacific Slope. When 
Packard wrote his Monograph of N. Am. Phyllopods only 
two species of that group were known ( /stherza Calzfor- 
nica P, and &. Newcombit Baird), and I believe no spe- 
cies has been added since. 

This species differs from Z. Couszz Packard, to which 
it is more nearly related than to any other American spe- 
cies, in the spinous crest and sides of the carapax, in the 
absence of a carina on the telson, in the greater length of

the caudal stylets and in several differences in the rela- 
tive proportion of the parts of the appendages. Judging 
from the measurements of the species described by Pack- 
ard, this is the largest of the North American species. 


Norr.—After the first part of the present article had 
been printed, I found that Ortmann had recently em- 
ployed the name Pseudopinnixa for a genus of Pinnother- 
ida, which is the same name that I proposed for an allied 
genus of the same family. I propose, therefore, to change 
the name of my genus to PARAPINNIXA.
