NEW GENERA AND SPECIES OF PHALAENIDAE^

(Lepidoptera)

BY FOSTER H. BENJAMIN

Bureau of Entomology, United States Department of Agriculture,

Washington, D. C.

The specimens discussed herein were, for the most part, set

aside by the author some six years ago in the Barnes collection

pending opportunity for comparison with large Neotropical col-

lections.

Two new genera and four new species are described; four

genera and two species are listed as heretofore unknown from the

United States.

Hadenin^

Ommatostolidea Benjamin, n. gen.

Type : Ommatostolidea julitce, new species

Tongue weak but functional; palpi short, upturned, the second

joint reaching slightly beyond the clypeus and fringed with long

hair below, the third short and porrect; frons relatively smooth,

slightly granular, lacking projections, except for a slightly raised

ventral transverse margin; clypeal plate disconnected, small; eyes

large and rounded, with sparse hair seen only with difficulty, the

individual hairs moderate in length, a few hair scales of the vesti-

ture droop over the eye from near the base of the antenna present-

ing a lashed appearance; antenna of female simple, ciliated; collar

clothed with broad scales and hair, remainder of thorax clothed

mainly with hair and lacking well defined scale crests although the

metathoracic hair tends to part into two diffused tufts; tibiae lack-

ing spines and claws, moderately fringed with hair; tarsi normally

spined; abdomen smoothly scaled, devoid of crests and tuf tings.

Fore wing narrow, elongate, costa and inner margin subparallel

except near base, apex acute, the termen oblique, scarcely rounded;

veins 3 and 5 from near angle of cell ; 6 from upper angle ; 9 from

10 anastomosing with 7 and 8 to form the areole, the stalking of

7 and 8 short; 11 from cell. Hind wing with vein 3 from near

angle of cell; 4 from angle; 5 obsolescent from somewhat below

middle of discocellulars, nearly parallel with 4; 6 and 7 shortly

stalked; 8 anastomosing with cell near base only.

THE PAN-PACIFIC ENTOMOLOGIST

[vOL. IX, NO. 1

Related to Ommatostola Grote, differing by the possession

of a weaker tongue; the shorter and more hairy palpi; the frons

not protuberant; the nearly parallel costal and inner margins

of the fore wing with straighter termen; and the broader scales

of the collar. Related to Eubuchholzia Barnes and Benjamin, the

fore wing similarly shaped but longer; lacking the strongly

bulged frons; the tongue weaker; the thoracic vestiture more

hairy.

Ommatostolidea julitae Benjamin, n. sp.

Head, thorax, and fore wing uniformly straw colored, lacking

all trace of markings ; the fringe of the fore wing pale cream color

and the only disconcolorous part of the wing. Hind wing, includ-

ing fringe, uniformly pale silken cream color. Abdomen concolor-

ous with the hind wing. Beneath, all wings and fringes concolor-

ously pale cream color. Expanse, 42 mm.

Type locality: Douglas, Ariz.

Holotype: Female, unique, dated “July,” Cat. No, 44331, U.

S. N. M.

CUCULLIIN^

Emariannia Benjamin, n. gen.

Type: Emariannia cucullidea, new species

Tongue strong; palpi porrect, short, not exceeding the frons,

fringed with hairlike scales below; antennas simple and ciliated in

both sexes, the joints tightly compressed, the cilia very short; eye

naked, with weak lashes from in front and behind; frons strongly

protuberant with a strong thin protuberant clypeal plate which is

connected on each end by a strongly raised oblique ridge to a long

central process that possesses a thin but strongly produced ter-

minal ring surrounding a large central excavation ; the frontal pro-

jections, with the exception of the terminal structure, hidden by

a dense vestiture of scales, the length of the total projection of

the frons and its armature being approximately one and a half

times the width of the eye; thorax clothed mainly with scales, the

collar produced to, a slight hood, the metathorax with a strong

pair of tufts; abdomen without crests or tufts; tibiae without

spines or claws; fore tarsus with the spines more curved, in a

clawlike fashion, than the spines of the mid and hind tarsi, but

not clawlike in size. Fore wing elongate, the apex rounded, the

termen nearly erect between costa and vein 5, thence inwardly

obliquely excurved to inner margin ; veins 3 and 5 from near angle

of cell; 6 from near upper angle; 9 from 10 anastomosing with

the short stalk of 7 and 8 to form the areole; 11 from cell. Hind

wing with veins 3 and 4 from lower angle of cell; 5 obsolescent,

bent at base somewhat more than normal for a trifid; 6 and 7

shortly stalked from upper angle.

Emariannia cucullidea Benjamin, n. sp.

Fore wing dull luteous mixed with black and some white; basal

line and dash obsolete; transverse anterior line obsolescent, fuscous,

produced into three long distal points, the medial point, somewhat

longer than the other two, includes the claviform area; orbicular

faintly outlined by fuscous, fiattened, whitish, practically con-

tiguous with the transverse anterior line; reniform faintly outlined

by fuscous, irregular, the upper half strongly crescent shaped and

filled with luteous, the lower portion recurved, filled with white

and produced to a mesial point near the extremity of the cell;

no median shade; median area largely appearing as fuscous gray

overpowdering a luteous ground; transverse posterior line fuscous,

geminate, the included space pale, waved, strongly excurved around

the cell, obliquely incurved below, outwardly defined by some gray

powderings; subterminal line obsolescent, pale, mainly defined by

a luteous shade in the distal half of the subterminal area some-

what contrasting with the terminal area which is slightly more

powdered with gray; terminal line thin, black, interrupted by thin

pale streaks which intersect the gray and black lined and inter-

lined fringe. Hind wings nearly pure silken creamy white in the

male; with a thin fuscous terminal line; fringe concolorous with

the wing; female with some fuscous powdering distally. Beneath

whitish, silken; male with the forewing darkened with fuscous

gray, the terminal lines and fringes as on the upper side; female

similar but with a very few fuscous scales powdering the costal

and distal portions of the hind wing. Expanse, 36 mm.

Type locality: Alpine, Tex.

eral outwardly oblique from costa to submedian fold, there ob-

scured, inwardly oblique below vein 1; claviform small, outlined

by black; orbicular obsolete, the basal area of the cell marked by

a rufous suffusion; an obscure powdery black median shade out-

wardly oblique from costa, contiguous with the base of the reni-

THE PAN-PACIFIC ENTOMOLOGIST

[vOL. IX, NO. 1

with an obscure dusky central crescent; transverse posterior line

geminate, defined by black, the included space pale, waved, bent

outward below costa, nearly oblique to about vein 4, thence obliquely

incurved to inner margin; subterminal line faint, ochreous, partly

defined and partly obscured by black powderings; with a heavy

black dash across the terminal and subterminal areas between

veins 1 and 2; and a shorter dash crossing the terminal area be-

tween veins 3 and 4; a terminal line of black dots between the

veins; fringe checkered fuscous and luteous. Hind wing fuscous

brown; with an obscure thin dark terminal line; fringe pale and

sordid. Beneath sordid whitish, the fore wing heavily suffused

with fuscous brown and black, with a blackish spot on the costa

marking the median shade and blackish powderings occupying the

subterminal area; the hind wing irrorated with fuscous which

forms an obscure discal mark and a subterminal shade. Expanse

32 mm.

Type locality: Brownsville, Tex.

Holotype: Female, unique, labeled “5-11” (Geo. Domer), Cat.

No. 44333, U. S. N. M.

Both Hampson (1908, Cat. Lep, Phal. B. M,, VII, 255) and

Draudt, (Seitz, Macrolepid., VII, 218) state that Speocropia pos-

sesses a raised edge on the conical projection of the frons (sim-

ilar to Euxoa). The author has examined specimens of every

species assigned to the genus by both Hampson and Draudt, in-

cluding the genotype “Wadena” scriptura Walker, and found the

frons cone shaped and tapering but lacking any raised rinl. The

coreous clypeal plate mentioned by both Hampson and Draudt

is well defined,

Agrotisia' evelinae Benjamin, n, sp.

Head dark, the vestiture mixed dark brown and black with a

few pale scales; collar mixed dark brown and black interrupted

by a few pale scales on basal two-thirds, distal third disconcolor-

ously paler, sordid violaceous ; thorax and tegulae sordid violaceous

speckled with a few fuscous scales; abdomen similarly colored,

somewhat more luteous. Fore wing washed with violaceous, tinted

with luteous brown, and marked with black; basal half line black,

geminate; transverse anterior line black, geminate, the inner part

not distinct, inwardly oblique from costa through the cell, thence

outwardly oblique, excurved in the submedian interspace and again

somewhat excurved below vein 1 where a black spot in the shape

of a circular triangle is formed; a heavy black blotch on the costa,

filling the area between the two aforementioned lines, and extend-

ing to slightly below the cell; orbicular absent; claviform prac-

tically absent, its position indicated by a luteous cast on the vio-

laceous ground; a median shade starts as an irregular black blotch

on the costa, obscures the reniform, proceeds in a generally out-

wardly oblique direction to vein 2, from thence being incurved and

inwardly oblique to the inner margin; transverse posterior line

geminate, black, waved, defined by two small black blotches on the

costa, excurved around the cell, and somewhat incurved to inner

margin ; subterminal line irregular, mainly defined by the powdery

black filling of the subterminal space, which possesses two small

pale points on the costa; a faint terminal dark line accentuated

into dots at the extremities of the veins; fringe luteous at base,

with pale tip and waved fuscous interline. Hind wings semi-

hyaline white; the costal margin, and to some extent the veins,

powdered with fuscous, which forms faint dots on veins 2, 3, 4,

and 6 indicating a median line; discal mark only visible because

of showing through the wing; a thin irregular fuscous terminal

line; fringe luteous at the base, with paler tip. Beneath: Fore

wing with pale ground heavily suffused with sordid fuscous brown

and powdered with black which marks the median and transverse

posterior lines and the filling of the subterminal space in the

costal area, terminal line and fringe as on upper side; hind wing

semihyaline white, powdered with some fuscous in the costal

region, with faint fuscous dashes on veins 2, 3, 4, 6, 7, and 8 in-

dicating a median line, and with a small fuscous spot marking the

middle of the discocellular vein; terminal line and fringe as on

upper side. Expanse 38 mm.

Type locality: Near Alpine, Tex.

Holotype: Male, unique, labeled 15-30 May 1926, (0. C.

Poling) ; Cat. No. 44334, U. S. N. M.

Apparently agrees with specimens from South America iden-

tified by Dr. Schaus as Agrotisia subhyalina in so far as the ex-

ternal generic characters are concerned. Hampson^ states that

A. subhyalina is “without distinct crests.” A half dozen examples

in the National Museum each have the thoracic vestiture too dis-

turbed to be studied. The type of evelince shows an indistinct

spreading crest on the prothorax.

THE PAN-PACIFIC ENTOMOLOGIST

[vOL. IX, NO. 1

A single poor female from Brownsville, Texas (Geo. Domer),

dated “7-11,” appears to be the same species.

Hypenin^

Raparna melanospila Gn.

1852, Guenee, Noct., II, 4, Euperia.

The following Florida specimens are in the National Collec-

tion. One male, labeled Chokoloskee, and two females, labeled

St. Petersburg, Sept. 24-30 ind Oct. 24-30, were received with

the Barnes material; one fernale, labeled Altamont, IX-17-1924,

(F. R. Cole), from the National Museum unsorted material.

The identification is based on a series from Cuba, Mexico,

and Venezuela, a Cuban specimen having been matched by Dr.

Schaus with the series in the British Museum. The generic name

Raparna is used, following a Hampson manuscript classification.

The species belongs to Smith’s “Pseudodeltoid” series, to the

beginning of the “Hypeninae” of Barnes and McDunnough, and

to the “Noctuinae” of Hampson’s revised version of 1926,“ vein

5 of the hind wing being rather weak but tubular, and parellel

to vein 4, the male without secondary sexual modification.

Temporarily the name may be added to the North American

Lists following Diallagma latiorella Wlk.

Tathorhynchus angustiorata Grt.

1882, Grote, Bull. U. S. Geol. Surv., VI, 584, Platysenta.

The placement of Reparna melanospila Gn. following Dial-

lagma latiorella Wlk. raises the question of what to do with

^^Diallagma^’ angustiorata Grote.

This species fits well into Hampson’s genus Tathorhynchus.^

HATCH— MISCODERA

THE SPECIES OF MISCODERA

( Coleoptera — Carabidae )

BY MELVILLE H. HATCH

Mis coder a insignis Mann, is known from Sitka, Alaska (Ham-

ilton, Trans. Am. Ent. Soc., XXI, 1894, p. 12) and Washington

(Seattle — 0. B. Johnson; Olympic Hot Springs — M. H. Hatch).

Miscodera arctica Payk., in its more typical phase, is known

from northern England, Scotland (Fowler, Col. Brit. Isl., I, 1887,

p. 26), the Swiss and Tyrolean Alps, Silesia, northern Germany,

Denmark, Norway, Sweden, Lapland, Finland, Leningrad, and

Esthonia (Jacobson, Kaf. Riissl. W.-Eur., 1910, p. 227). Horn

(Trans. Am. Ent. Soc., IX, 1881, p. 168) held that the Siberian

and North American forms known as erythropus Mots., ameri-

conus Mann., and hardyi Chaud. were not distinct. More recent

authors, however, (Ganglbauer, Kaf. Mitteleur., I, 1892, p. 145;

Jacobson, l.c.) regard these as constituting the subspecies erythro-

pus Mots., which has the following distribution: Siberia (L.

Baikal, Transbaikalia, Amur, Yakuts) (Heyden, Cat. Col. Si-

birien, 1880-81, p. 24; Jacobson, l.c.) ; Alaska (Kenai) (Hamil-

ton, l.c.) ; Washington (Bonaparte Mt., 5000 to 7000 ft. — M. C.

Lane) ; Alberta (Glacier L., 4800 ft.) (Thorington, Ent. News,

XXXVHI, 1927, p. 178-180) ; Montana (Grasshopper Glacier,

9000 ft. — M. C. Lane) ; Ontario (Cochrane) (Notman, Jour.

N. Y. Ent. Soc., XXVH, 1919, p. 93) ; Michigan (White Fish

Point) (Andrews, Pap. Mich. Acad. Sci. Arts and L., I, 1923,

p. 337) ; New York (Keene Valley) (Leonard, Cornell Univ.

Agr. Exp. Sta., Mem. 101, 1926, p. 241) ; Maine (Eastport,

Barber); Newfoundland (Horn, l.c.). Hubbard and Schwarz

(Proc. Am. Phil. Soc., XVII, 1878, p. 628) record it from Lake

Superior without further designation of locality.

The five Washington specimens of arctica before me agree

closely with Ganglbauer’s description (l.c.), except as regards

the dorsal striae. In the Washington specimens the second stria

is indicated by an unimpressed series of punctures at about the

basal two-fifths; the other striae are completely wanting. Gangl-

bauer reports traces of five unimpressed series of punctures

lateral to the impressed sutural stria. This may constitute the

difference between typical arctica and the subspecies erythropus

Mots.

THE PAN-PACIFIC ENTOMOLOGIST

[vOL. IX, NO. 1

On the basis of the Washington material before me and Gangl-

bauer’s description, the species and subspecies of the genus may

be distinguished as follows.

A. Rufous to piceo-rufous, the legs and antennae paler; head

without a transverse impression between eyes; apex of maxillary

palpus rounded; pronotum longer than wide, the sides more broadly

rounded, the basal constriction nearly obsolete at the middle, the

base not longitudinally rugose; elytra with nine entire impressed

striae; length 9 mm.; Alaska, Washington insignis Mann.

AA. Shining black or dark rufous, the legs and antennae paler;

head with a transverse impression between eyes ; apex of maxillary

palpus truncate; pronotum as wide as long, the sides more strongly

rounded, the basal constriction impressed throughout, the base

longitudinally rugose towards the hind angles; elytra with the

striae, except the sutural, consisting of more or less obsolete un-

impressed series of punctures; length 6.5-7 mm arctica Mots.

B. Striae two to six represented by more or less extensive un-

impressed series of punctures. Great Britain and Scandinavia to

Switzerland, Tyrol, Silesia, Leningrad, and Finland subsp.

arctica s. str.

BB. Elytral striae (in Washington specimens), except the

sutural, obsolete, stria two only being represented by an unim-

pressed series of punctures at about the basal two-fifths. Eastern

Siberia through Alaska to northern Washington, northern Michi-

gan, northern New York, Maine, and Newfoundland subsp.

erythropus Mots.

I have no hesitation about pronouncing insignis Mots, the

more primitive of the two species on the basis of its striate elytra

and less specialized head and pronotum.

William Jacob Holland

It is with deep regret that we record the passing of our veteran

lepidopterist Dr. W. J. Holland, who died on December 13, 1932,

at the ripe age of 84 years. His Butterfly Book and his Moth Book

have been the guides and inspiration of our younger lepidopterists

for many years. But Ittle more than a year ago he completed a

careful revision of the Butterfly Book bringing it up to date and

placing us all under a renewed obligation. Dr. Holland had a

broad knowledge of the Lepidoptera founded upon a basis of

sound nomenclature. His large collection of butterflies, includ-

ing the W. H. Edwards collection and much invaluable type ma-

terial, is now in the Carnegie Museum.

SALMAN— A NEW PEPSIS

A NEW SPECIES OF PEPSIS FROM ARIZONA

( Hymenoptera — Psammocharidae )

BY KENNETH A. SALMAN

Berkeley, California-

The material from which this species is described was en-

countered in collections of Dr. Jos. Bequaert and the American

Museum of Natural History which were examined while the

writer was a graduate student at the Massachusetts Agricultural

College, Amherst, Mass.

Pepsis hirsuta Salman, n. sp.

Female. Length 34 mm. Body and legs black with bluish or

purplish pile. Antennae black, shading to brown in the outer seg-

ments. Wings yellowish brown with black basal band about one-

sixth the length of fore wings and one-fourth the length of hind

wings ; apical field fuscous, somewhat darker near margin of wings.

Head, thorax, propodeum and abdomen thickly hairy, particularly

beneath. All femora with long, thickly placed hairs beneath. Cly-

peus broadly convex; margin weakly and arcuately incised. Epi-

cranial furrow distinct. Vertex rather strongly sculptured. Inner

eye margins slightly convergent above. Third antennal segment

distinctly shorter than width between eyes across vertex. Antennas

thick, tapering to apex; inner surface, particularly of segments

near apex, flattened.

Shoulders of pronotum rounded; anterior surface convex; pos-

terior margin arcuate. Scutum convexly arched anteriorly, flat-

tened posteriorly. Scutellum broadly rounded above. Mesopleural

tubercles wanting. Antero-lateral and postero-lateral surfaces of

middle and hind tibiae with distinct longitudinal furrow extending

from near base almost to apex. Inner tibial spur of hind leg more

than half the length of basitarsus.

Propodeum very hairy; horizontal and sloping surfaces dis-

tinct. Horizontal surface rather regularly convex; median carina

distinct, flattened above or with weak median longitudinal fur-

row; lateral carinas indistinct; lateral teeth moderately developed

although nearly hidden by hairs; subspiracular tubercle well de-

veloped; transverse ridge moderately high, short, flattened above.

Sloping surface weakly convex; excavated immediately behind

transverse ridge; surface weakly rugose. Posterior lateral angles

of propodeum rounded. Abdomen flattened dorsoventrally. Ventral

furrow of second sternite distinct, although not deep, sinuate and

without well marked posterior prolongations.

Holotype. Female. Southern Arizona (Bequaert). Deposited

in the collection of the Museum of Comparative Zoology at Har-

vard University, Cambridge, Mass. Paratype. Female. Yavapai

THE PAN-PACIFIC ENTOMOLOGIST

[vOL. IX, NO. 1

Co., Arizona. August (0. Buchholz Coll.). Deposited in the

collection of the American Museum of Natural History, New

York City.

This species agrees very closely with the existing descrip-

tions of Cassandra Mocs., but differs from the characters given

for that species by Lucas to a slight extent. In view of the fact

that Cassandra has been reported only from Chile in South Amer-

ica while hirsuta is known only from Arizona, it appears improb-

able that they are the same. Hirsuta is distinct from any other

species of Pepsis that has been reported from North America.

Three species, cassiope Mocs., hirsuta n. sp. and cassandra

Mocs. apparently form a compact group having longitudinal

furrows on the middle and hind tibiae, hairy bodies and flattened

abdomens as characters in common. It is felt that some recog-

nition should be given this group but, in view of the fact that

the males of these species are not known, confusion instead of

clarity might result by giving the group a subgeneric designation.

Barton Warren Evermann

Since the appearance of the last number of the Pan-Pacific

Entomologist the California Academy of Sciences has met with

a great loss in the death of its Director, Dr. Barton Warren Ever-

mann, that occurred on September 27, 1932. Dr. Evermann was

a true naturalist in the broadest meaning of that term. While not

an entomologist as we generally use that word, he was deeply

interested in the development of the Department of Entomology

of the Academy and did all he could to advance the research

activities of that department. His interests were as broad as the

field of biological science, and the advancement of research in

all departments of the Academy during his administration, ex-

tending from 1914 until his death, was limited only by the funds

available. He was a leader in the scientific work on the Coast,

a most genial companion and a true friend, and his loss will be

a personal one to the scientific workers of this country and espe-

cially to those in the West. — E. P. Van Duzee.

CHAMBERLIN— MYRIOPODA

ON A COLLECTION OF CENTIPEDS AND

MILLIPEDS FROM COSTA RICA

BY RALPH V. CHAMBERLIN

The following lists are based on two small but valuable col-

lections of centipeds and millipeds made during the years 1928,

1929 and 1930 at various points in Costa Rica by Prof. M.

Valerio of San Jose, Costa Rica, by whom they were transmitted

to me for identification. I am much indebted to Prof. Valerio

for the care with which he has brought this material together

and for his courtesy in turning it over to me for study.

The types of the new forms are in the author’s collection.

Gosibiid^

Gallitobius Chamberlin, new genus

A genus of the family Gosibiidae related to Arenobius and

Mexicobius. From the former it differs in having the antennae

composed of numerous articles (in the genotype above 40) in-

stead of being composed constantly of 20, and also in having

the prostemal teeth numerous (e.g., 4-1-4 and 6-|-6) instead of

2-|-2; the ectal spine dentiform, very small. Margin of head

not broken or interrupted. From Mexicobius it differs also in

having the numerous prostemal teeth. The ninth, eleventh and

thirteenth dorsal plates with posterior angles produced. Male

not known.

Genotype. G. ethophor Chamberlin, new species.

7. Gallitobius ethophor Chamberlin, n. sp.

Dorsum in general chestnut in color with a partly obscure

median longitudinal darker stripe. Antennse chestnut brown. Legs

yellowish or somewhat brownish yellow, the posterior pairs darker.

Antennae long; in the holotype composed of thirty-nine articles.

Ocelli arranged in three series; e.g., 1 + 3,3,2; the single ocellus

large, contiguous with the group, the first ocellus of the top series

also notably enlarged.

Prosternum with anterior margin on each side nearly straight,

transverse; teeth rather small, dark, in number 4 + 4; the ectal

spine dentiform but low and almost obsolete, in line with the teeth.

Length 26 mm.

Locality: El Gallito. One female taken Dec. 30, 1927.

8. Gallitobius ricanus Chamberlin, n. sp.

A much darker species than G. ethophor, the dorsum being a

dark mahogany.

Antennas composed of 43 - 44 articles. Lateral margin of head

smooth without interruptions. Ocelli nine in number, arranged as

follows: 1 + 2,2, 3,1; the single ocellus very large and the caudal

ocellus of top series almost as large, while the ocelli of the bottom

series are very small.

reduced or obsolete. (See page 13, fig. 1.)

Gonopods of female with basal joint strongly chitinized and

excavated within at base. Basal spines 2 + 2. Claw entire.

Anal legs slender, bearing ventrally 0,1,3,3,2 spines and ter-

minating in two claws. No spines detected on posterior coxae but

the poor condition of the type specimen renders full certainty as

to this impossible.

plates produced strongly, those of the seventh also a little angularly

produced. Surface of tergites strongly rugose.

Coxal pores circular, in a single series.

M. Valerio, date not given.

This species differs from G. ethophor especially in the more

numerous prosternal teeth and in having the basal spines of the

female genital forceps 2 -|- 2 instead of 3 -|- 3. It is a much

darker species and has the posterior angles of the seventh tergite

a little acutely produced which in G. ethophor is not the case.

COCKERELL— BOREGO BEES

BEES COLLECTED AT BOREGO, CALIFORNIA, BY

WILMATTE P. COCKERELL AND MILENE PORTER

BY T. D. A. COCKERELL

The following bees were collected at Borego, San Diego

County, California, April 3, 1932.

Spinoliella puellae Cockerell, n. sp.

Female (Type). Length about 9.5 mm.; black, the head and

thorax with abundant long greyish white hair; head broad, wholly

without light markings, clypeus and sides of vertex highly polished ;

eyes intense black; lower part of clypeus with scattered strong

punctures; flagellum short and stout, ferruginous beneath except

at base; a highly polished semicircular area in front of and sur-

rounding middle ocellus, interrupted in middle anteriorly by a nar-

row sulcus; mesothorax polished, anteriorly with scattered deli-

cate punctures; scutellum polished, with a shallow median sulcus;

tegulae brown; wings hyaline, a little dusky, stigma very dark

reddish; basal nervure falling far short of nervulus; first recur-

rtent nervure joining second cubital cell very near its base, second

far from its apex; legs without light markings, tuft on hind knees

pale reddish; first four tergites with entire canary-yellow bands,

more or less narrowed in middle and broadly, shallowly emargi-

nate posteriorly at sides; fifth tergite with a pair of transverse

yellow marks, rounded in front, straight behind; apex with pale

reddish brown hair; venter with transverse pallid depressions at

the median bases of the stemites.

Male similar but narrower; clypeus all black, or with an in-

conspicuous median pale yellow line; lateral marks extending as

a line along orbits up to level of antennse, but at lower end

broadened, with a hook-like extension; flagellum short, very ob-

scurely reddish beneath; fifth tergite, in addition to the two trans-

verse marks, having a little spot at each extreme side, or the

fifth may have an entire band, extending to sides, or the lateral

spots may be wanting.

The females had collected the very pale pollen from a species

among those with black face in female, by the entire bright

yellow abdominal bands and rather large size. The labial palpi

are of moderate length but much longer than in S. comptula

enormously elongated, longer than the head, while the other three

are very minute. S. euxantha (from Claremont, California) must

Hesperapis wilmattae Cockerell, n. sp.

Female: Length nearly 8 mm., anterior wing slightly over 6;

black, the sides of face, front, occiput and cheeks with long white

hair; long white hair also on pleura and sides of metathorax,

but mesothorax, which is minutely punctured and hardly shining,

pruinose with excessively short thin hair, giving it a dusty appear-

ance; the scutellum is similar, but with some longer hair; facial

quadrangle about as broad as long, orbits somewhat converging

below; clypeus convex, smooth and highly polished; supraclypeal

area polished; flagellum short and thick, red beneath except at

base; sides of front shining, but finely and closely punctured; area

of metathorax large, entirely dull; apical truncation shining, with

a very large and deep central pit; tegulae small, testaceous; wings

hyaline; stigma large, lanceolate, clear ferruginous, nervures fus-

cous ; second cubital cell very long, receiving first recurrent nervure

some distance from base, and second still more remote from apex ;

legs black, with middle and hind knees red; apical margin of hind

tibiee red; mid tibiae densely covered on outer side with white hair,

on inner side bare and polished; abdomen dull, extremely densely

and minutely punctured, basal declivity of first tergite polished;

second and following tergites with a thin very short covering of

somewhat reddish hair; tergites 1 to 5 with broad dense white

hair-bands; apical plate reddish, narrowing to a truncate, feebly

emarginate, end; maxillary palpi six jointed, the last three of equal

length, and only a little shorter than those before.

One specimen. Related Xo H. fuchsi (Vier.) in several re-

spects, but smaller. The abdomen resembles that of H. pellu-

cida Ckll. which, however, has a polished mesothorax. The

thoracic pubescence recalls that of H. elegantula Ckll.

Osmia liogastra Cockerell, n. sp.

9 Length hardly 7 mm., anterior wing hardly 5; robust with

broad head, rather small thorax, and very broad and short abdo-

men; thorax and abdomen shining olive green, head darker and

duller (very densely punctured), the lower part of the clypeus

black; tegulas very dark brown, not at all metallic; legs entirely

black; ventral scopa black; pubescence white, very faintly yellow-

ish on tubercles and thoracic dorsum; scattered long inconspicuous

black hairfs on the thorax above. Mandibles black, tridentate;

clypeus simple, densely punctured, the apical margin shining, with

the lateral angles prominent; hair at sides of face pure white, but

that on clypens yellowish, contrasting; front with a median

groove; flagellum short, dark red beneath except basally; third

antennal joint nearly twice as long as fourth; area of metathorax

moderately shining, at base with very fine plicae and beyond with

a miscroscopical cancellate sculpture; basal nervure meeting ner-

vulus; first recurrent nervure as distant from base of second cubi-

tal cell as length of first intercubitus, but second recurrent scarcely

half as far from end of cell; hair on inner side of hind basi tarsi

dark brown; abdomen shining, very finely punctured, with white

hair at sides, on tergites 3 to 5 forming very thin imperfect bands.

One specimen. It is evidently polytropic as it has gathered

three kinds of yellow pollen, two of Compositae and the third

(most abundant) I fail to recognize.

In the tables of Pacific Coast and Canadian Osmia by Miss

Sandhouse and in my table of Rocky Mountain species, this runs

persistently to 0. phacelice Ckll. It is, however, much smaller

and quite differently colored. I had to consider whether it could

be the unknown female of 0. nemoris Sandhouse, but the lack

of metallic color on the tegulae, and other characters, seem to

make this improbable. The position of the recurrent nervures

differs conspicuously from that of 0. nemoris.

Megachile xerophila Cockerell, n. sp.

Female: Length about 10 mm., anterior wing a little over 6;

black, robust, with large head and heart-shaped abdomen; pubes-

cence rather abundant, erect, clear white, not mixed with black,

but black on last two sternites or (on the second specimen) last

sternite and apical part of penultimate one; mandibles with two

large apical teeth, and a long oblique cutting edge, leading to the

obtuse inner corner; clypeus prominent, the upper part convex,

the lower middle flattened; the upper part very densely punctured

and dull, the lower more shining, with the larger punctures more

irregularly placed; lower margin simple; some red hairs from

under side of mandibles; vertex dull and finely punctured; an-

tennae entirely black; third joint above one-fourth longer than

fourth; mesothorax entirely dull, the sculpture consisting of a

microscopical reticulation, on which are scattered shallow punc-

tures, distant from each other about two punctures width; scu-

tellum dull with indications of a shining median line; tegulae very

small, black with white hair in front; wings clear, very faintly

dusky apically, nervures black; basal nervure falling considerably

short of nervulus; second cubital cell receiving recurrent nervures

close to, and about equally distant from, base and apex; legs black,

with white hair on outer side, dark brown on inner side of front

and hind basitarsi, but clear red on middle pair seen from in front;

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 1

spurs pale reddish; hind basitarsi rather broad, longer than the

remaining joints together; abdomen shining, with five very dis-

tinct clear white' hair-bands ; sixth tergite straight in lateral pro-

file, covered with a fine white pruinose pubescence; white hair of

scopa very clear and bright.

Two specimens. Mitchell, in his recent table of neotropical

Megachile, has used some characters not hitherto cited, so I

thought it worth while to run our species through it. It comes

out quite definitely at M. affabilis Mitch., differing by the lack

of black hair on pleura. M. affabilis from Paraguay is really

a quite different species. In my table of Lower California species

(1924), M. xerophila runs straight to M. vanduzeei CklL, and

is quite without spots or bands of pubescence on the thorax above.

M. vanduzeei has a similar aspect but is much larger, with a band

of white pubescence in front of scutellum and quite different

mandibles. The mandibles and sixth tergite exclude our species

from a number of superficially similar small forms. One of

the specimens was taken at evening primrose but had not col-

lected pollen.

A Note on Andrena nudimediocornis Vier.

Andrena pallidiscopa trifasciata

Timberlake and Cockerell, n. subsp.

Andrena nwdimediocomis Viereck, Cockerell, Pan-Pacific Ento-

mologist, VIII (1932) p. 176.

The species described as A. nudimediocornis, from Gavilan,

California, was considered by both of us to represent a new

species, A. trifasciata. After the description was sent for publi-

cation, Timberlake borrowed paratype material of A. nudimedio^

cornis Viereck, a species very briefly indicated, but not really

described by Viereck in the Canadian Entomogolist XXXVI

(1904) p. 227. Viereck’s material was taken at Corvallis, Ore-

gon in May and June, by Cordley. It appeared upon comparison,

that in spite of some differences, this A. nudimediocornis was the

same species as A. trifasciata, and accordingly Viereck’s desig-

nation was substituted in proof.

We have now both examined the paratype of A. nudimedio-

cornis in comparison with A. trifasciata, and conclude that the

latter should stand as a valid subspecies, the differential char-

acters being constant and clearly discernible as follows:

rmdim edioco rnis

Clypeus rather more shining,

with a distinct median ridge

Tibial scopa dull white be-

neath

Caudal fimbria light reddish

or more dusky

Venter of abdomen with much

pale hair

Stigma ferruginous

Nervures mostly pale reddish

trifasciatcb

Clypeus dull, with the median

ridge only feebly indicated on

lower part

Tibial scopa black beneath

Caudal fimbria black or dark

soot color

Venter without any conspicu-

ous pale hair

Stigma very dark brown

Nervures dark

A. trifasciata is also perceptibly larger than the other. With

all these differences, the two insects are nevertheless extremely

alike, so that it is considered best to treat them as subspecific

forms of a single species, until or unless the male of the Oregon

insect should show structural differences.

Many years ago Viereck (in litt.) stated that A. nudimedio-

cornis was identical with A. pallidiscopa Viereck, which is indi-

cated higher up on the same page in the Canadian Entomologist,

and was collected by Cordley at Corvallis, June 1. A speci-

men of A. pallidiscopa, determined by Viereck, is in the Cockerell

collection. It is from Colorado, C. F. Baker, 1900, and is not

to be separated from the paratype A. nudimediocornis. Hence

the name A. pallidiscopa is to be used for the species.

Some of the characters of A. pallidiscopa appear to ally it

with A. sapellonis Ckll. as given in the table. But A. sapellonis

is very easily distinguished by the abundant long light hair on

the thorax above, and the smaller, more tapering metathorax.

A. pallidiscopa has a dense tibial scopa, with coarsely

branched hairs on outer side, and so falls in the subgenus

Pterandrena Robertson, as Viereck indicated. In a manuscript

key to Pterandrena, trifasciata falls next to A. asteris Rob., which

it closely resembles in many respects, but it is easily distinguished

by several obvious characters. — P. H. Timberlake and T. D. A.

THE MALE OF VANDUZEEINA SLEVINI USNG.

(Scu telle ridse, Hemiptera)

BY R. L. USINGER

In a previous paper^ the author described V anduzeeina slevini

from a unique female. Since that time the male has been taken

and is described below.

Vanduzeeina slevini Usinger

Male. Similar to the female in general appearance, vesti-

ture long and fusco-testaceous, margins of the pronotum more

nearly parallel than in V. balli Van D., eyes vertical and more

narrowed than in balli and the legs more robust. Size much

smaller than in the female, 4.7 mm.

Head similar to that of balli, very slightly more narrowed

apically, tumid, the tylus distinctly surpassing the juga; eyes ver-

tical, more narrowed than in balli. Pronotum transverse, dis-

tinctly less widened behind than in balli, lateral margins rather

evenly arcuate throughout, in balli more rectilinear anteriorly and

strongly arcuate posteriorly; calli slightly elevated, separated by

a narrow smooth area from the rest of the pronotum which is more

irregularly punctate than in balli; the transverse median de-

pression, which apparently is found in all species of this genus

and extends to the lateral flattened area, is less distinct than in

balli. Scutellum much as in balli with the punctation scarcely less

dense and more irregular, indistinct or wanting anteriorly and

posteriorly. As the hemelytra are partially spread the connexivum

is obscured but appears, through the membrane, to be unicolorous

as contrasted with the distinctly alternated connexivum of balli.

A long fusco-testaceous vestiture forming a rather dense cover-

ing on the dorsum. Vestiture sparse, white, flne, and long on the

venter. Legs appearing more robust than in balli. Antennal char-

acters, which differ in the females of the two species discussed

here, are not present in the males, the fourth segment being dis-

tinctly longer (23:15) than the third in both species. Rostrum

reaching posterior part of intermediate coxae.

Color black, mottled with fusco-testaceous between the punc-

tures behind the transverse depression on the middle of the pro-

notum, and on the scutellum except for a median triangular area

at the base. Ventral surface black, more highly polished anteriorly

than on the venter. Antennae becoming fuscous apically. Tarsi

fuscous.

Described from a single male taken by Lawrence W. Saylor

at Santa Cruz, Calif, on August 1, 1931. The above specimen,

which might be designated either as an allotype or a neallotype,

is in the author’s collection.

A SHORT REVIEW OF DYSLOBUS LeCONTE, A GENUS

OF BROAD-NOSED WEEVILS OF THE SUBFAMILY

OTIORHYNCHIN^ WITH DESCRIPTIONS

OF NEW SPECIES

BY EDWIN C. VAN DYKE

University of California, Berkeley, California

This paper was written primarily to assist certain field work-

ers who wished to know what weevils they were dealing with

and at the same time to straighten out the confusion that has

existed for some time with regard to many of our species. In

this work I have not only had the use of my own very large col-

lection but the material of the California Academy of Sciences

including the collection of my associate, Dr. F. E. Blaisdell,

extensive series submitted by Mr. Wm. W. Baker and Mr. Joseph

Wilcox of Puyallup, Washington, and the aid of Mr. L. L.

Buchanan of the U. S. National Museum who has generously

and painstakingly compared many of my specimens with the

Casey and Pierce types. I am also under obligations to Dr. J. M.

Aldrich and the U. S. National Museum for the loan of two

paratypes.

Genus Dyslobus LeConte

The genus as used here includes not only Dyslobus LeConte,

but Amnesia Horn, Tricomigus Horn and Melamorphus Horn.

Pierce^ united a portion of Amnesia with Dyslobus and the re-

mainder with Tricomigus under Melamorphus... The species of

Amnesia united under the last name are less differentiated from

the more typical species united with Dyslobus than are these

typical Amnesia from Dyslobus. That being the case it seems

best to unite them all as a part of one great complex, as they

are, under one name. They cannot be separated by any funda-

mental characters and their geographical distribution confirms

their common relationship.

sixth, the club fusiform. Pro thorax barely broader than long, with

sides slightly arcuate, faintly constricted near apex, broadest in

front of middle, the disk, like the head, rather finely, closely punc-

tured but with sculpturing concealed by scales, postocular lobes

but moderately developed and finely fimbriate. Elytra one-third

longer than broad in male, slightly broader in female and in the

latter broader than prothorax, humeral angles not well defined,

sides of elytra arcuate to base, striae fine, slightly impressed and

with punctures of moderate size, approximate and each containing

a small scale, intervals fiat or barely convex and equally elevated,

suture evenly arcuate from disk to apex of elytra and without

keel at summit of declivity. Beneath regularly but not densely

squamulose and finely pilose, first ventral segment sulcate at cen-

ter, deeper in male, the fifth narrowly sulcate in male and sub-

carinate in female. Anterior tibiae denticulate and arcuate to-

wards apex, median simple and straight, hind tibiae simple and

feebly arcuate towards apex, all tibiae mucronate. Length 11

mm., breadth 3.5 mm.

Holotype male (No. 3664), allotype female (No. 3665, Mus.

Calif. Acad. Sci.) and several designated paratypes from a

series of 170 specimens. The type locality is Homestead Inn,

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 1

Mt. Hood, Oregon, July 3, 1927, but I have also taken specimens

on Mt. Adams, Wash., Hood River and The Dalles, Oregon, and

have studied others from Easton, Wash., belonging to the Koe-

bele Collection.

This species belongs near segnis but may readily be sepa-

rated in general by its smaller size, brighter appearance, lack

of well defined humeral angles, even curvature of elytra and but

slightly angulated posterior tibiae in males. It is also geographi-

cally isolated being a Cascade Mountain species while segnis is

primarily a California mountain species. On Mt. Hood it is very

common, being found upon almost every available tree or shrub,

especially in old logged over areas.

Dyslobus verrucifer Casey

This large, distinctly gray, somewhat tessellated species with

well marked tubercles at the summit of the apical declivity of

the elytra, is quite northern in its distribution being found in

the northern Cascades and northern Rocky Mountains. In the

Cascades it is most frequent at high levels, chiefly in the forest

of alpine hemlock not far below snow line but in Idaho and in

Yellowstone Park it drops to lower altitudes. The tubercle is

quite variable, small and single or large and double. D. bituber-

culatus Pierce is nothing but a form with larger tubercles. Mr.

Buchanan has accurately compared some of my specimens with

the type and verified my surmise.

Dyslobus denticulatus Pierce

This insect is quite similar to lecontei and in fact is a deriva-

tive of the same. Like it, it is a coastal species, has the serial

punctures of the elytra coarse, giving lodgement to squamae and

the scaly covering metallic and generally greenish. It is, how-

ever, readily separated by the more prominent humeral angles,

more convex elytral intervals with a tendency to be alternately

more evidently elevated, especially posteriorly, and the pronotum

tuberculate, a character overlooked by Pierce. Collecting in

intermediate territory may show that this species is but an ex-

treme of lecontei.

Dyslobus granicollis (LeConte)

This species with its varieties is the most widely dispersed

of the genus, ranging from western British Columbia as far south

VAN DYKE— DYSLOBUS

as Monterey Bay, in California, in fact throughout most of the

typical Vancouveran faunal region. In its typical form, it ex-

tends as far south as Humboldt County, California. From here

south, it begins to break up into minor races, chiefly characterized

by the males becoming more elongate; with the humeri more

prominent, the elytral intervals alternately more elevated and

tuberculate at the summit of the declivity and with as pronounced

a development of the granules on the elytra as there is on the

pronotum. D. sculptilis (Casey) and discors (Casey) are

variants of such slightly differentiated features that they should

be suppressed as synonymous. D. dehilis (Casey) is but a de-

pauperized, narrower variety. It simulates tumida but is smaller

and lacks the elytral granules. D. tumida Casey is, however, a

well defined extreme which because of great development of the

elytral humeri, and alternate intervals, with tubercles at summit

of declivity and elytral granules, should remain as a named sub-

species. A second subspecies which will now be defined is also

worthy of being designated.

Dyslobus granicollis vestitus Van Dyke, new subsp.

This subspecies is black or very dark brown, scales large

and very dull as is the body color. It resembles the typical

granicollis in having the granules confined to the prothorax, the

alternate elytral intervals but little more elevated than the others,

and the scales of the elytra densely placed. Its distinctive fea-

tures other than color, are the coarsely and densely granulate

prothorax, the granules almost twice as numerous as in typical

forms, the great reduction of pronotal scales as a result; and

the dense clothure of the upper surface with short, semierect

black hair, the vestiture fully twice as abundant, more regular

and more erect than in any of the other phases of the species.

Male, length 11.5 mm., breadth 4.25; female, length 12 mm.,

breadth 5 mm.

Holotype male (No. 3666), allotype female (No. 3667), Mus.

Calif. Acad. Sci.), and sixteen paratypes collected by Mr. E. R.

Leach and Mr. E. P. Van Duzee at Yorkville, Mendocino Co.,

Calif., June 10, 1921, and various other dates. Most of the para-

types are now in the collections of Mr. E. C. Zimmerman and

Mr. Leach through whose kindness I received several of my speci-

mens.

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 1

Dyslobus viridescens Van Dyke, new species

Similar in form and general appearance to granicollis but gen-

erally smaller, with the majority of the scales proportionately

smaller and somewhat green, the granules of prothorax much sup-

pressed, rarely appearing above the general surface, the outer

segments of the antennal funicle moniliform, not elongate, and the

serial punctures of elytra brilliantly green and squamigerous. Head

coarsely punctured, moderately clothed with elongate green scales;

rostrum two and a half times as long as broad, rugose punctate,

depressed and shallowly sulcate in front, and separated from head

by a slight transverse impression; eyes flattened; antennal scape

reaching hind margin of eyes, first and second funicular segments

elongate, third slightly longer than broad, the club fusiform and

twice as long as broad. Prothorax a bit broader than long with

or without median sulcus and laterally irregularly impressed.

Elytra two-flfths or over broader than long, the humeral angles

well defined, somewhat auriculate, odd intervals well elevated. Be-

neath punctate granulate, the males with first abdominal seg-

ment slightly sulcate, the females with last segment obtusely cari-

nate. Anterior tibias denticulate and strongly bent near apex.

Length 9 mm., breadth 3.25 mm. in male and 4 mm. in female.

Holotype male (No. 3668), allotype female (No. 3669, Mus.

Calif. Acad. Sci.) and four paratypes, the first three from Can-

non Beach, Ore., June 12 and 15, 1923, the others from Olney

(near Astoria), Ore., June 13-15, 1925. I have also closely as-

sociated with these, four other specimens, one from Cannon Beach,

two from Olney and one from the Forks, Wash., July 3, 1920,

collected by E. P. Van Duzee, which only differ from the pre-

ceding in having the squamae in the serial punctures of the elytra,

very narrow, practically setigerous.

This species belongs to a group of moderate sized species in-

cluding besides the above, squamipunctatus, wilcoxi, and hakeri,

all somewhat related to granicollis, in fact superficially very like

the variety dehilis Casey, of which this species is the closest rela-

tive, the others being more divergent.

Dyslobus wilcoxi Van Dyke, new species

Small, robust, piceous, elytra densely clothed with metallic

golden brown scales, the remainder of insect somewhat sparsely

clothed, the scales beneath slightly greenish, and with short, much

inclined setae. Head sparsely, shallowly punctured, the latter gen-

erally concealed beneath the squamae; rostrum at least twice as

long as broad, separated from head by a shallow transverse im-

pression, shallowly sulcate in front and with a well defined median

longitudinal carina; eyes much flattened, barely projecting beyond

side margins; antennal scape reaching hind margins of eyes, the

first and second funicular segments elongate, the first the longer,

the third to sixth short, moniliform, seventh slightly larger, the

club fusiform, over twice as long as broad. Prothorax slightly

broader than long, sides evenly arcuate from base to apex or

barely constricted before apex, broadest at middle, disk regularly

verrucose, each tubercle finely punctured at apex and with narrow

and sharply defined median longitudinal impression, the postocular

lobes well defined and fimbriate. Elytra less than twice as long as

wide in male, and about one-fourth longer in female, distinctly

broader than prothorax in both sexes, the humeral angles quite

prominent, the sides of elytra sinuate before base as well as to-

wards apex, the third, fifth and seventh intervals distinctly more

elevated than the alternate ones in the males and slightly more

elevated in the females, especially posteriorly, striae slightly im-

pressed and with moderately large punctures, each giving rise to

a small seta. Beneath coarsely, rather closely punctured, ventral

segment somewhat rugose, especially in males, the prostemum

slightly tuberculate behind anterior legs. Males with first ventral

segment shallowly sulcate and last ventral convex and often slightly

impressed at apex, the females with first ventral non-sulcate and

the last ventral obtusely carinate. Anterior tibiae denticulate and

slightly bent near apex. Length 7 mm., breadth 2.5 mm. in male

and 3.25 in female.

Holotype male (No. 3670), allotype female (No. 3671), Mus.

Calif. Acad. Sci., and several designated paratypes from a series

of fifty-four specimens collected by J. Wilcox at Lacomb, Ore-

gon, May 27, 1931, and June 7, 1929, mostly on strawberries.

Most of the material remains in Mr. Wilcox’s hands.

This is one of the smallest of our species and may generally

be distinguished by its small size, rather uniform dull golden

color above, regularly verrucose pronotum, prominent humeri

and elevated alternate elytral intervals. From hakeri with which

it might be confused, it can be separated by being in general

slightly smaller, more uniformly colored, having prominent hu-

meri and lacking the prosternal spine.

Dyslobus decoratus (LeConte)

This species might also be confused with small specimens of

granicollis. Its distinctive features are that the pronotum is

irregularly tubercular or verrucose with small punctures at the

summits of the tubercles, not regularly studded with smooth

granules as in granicollis, that the elytral intervals are less un-

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 1

equally developed and the underside more grossly punctured. It

ranges from British Columbia south as far as Trinity Co,, Cali-

fornia and Plumas Co, in the Sierras, In a race collected at

Silverton, Oregon, by Wilson and Mote, the pile is slightly longer

and more evident than in normal forms,

Dyslobus raucus (Horn)

D. ciliatus Pierce is but a slightly larger phase of the above.

Its range is continuous with raucus and it possesses no char-

acters to differentiate it, Mr, Buchanan who has made careful

comparisons for me, agrees with me entirely in reducing it to

synonymy.

Dyslobus tanneri Van Dyke, new species

Of moderate size, robust, piceous, head and pronotum sparsely

and elytra densely clothed with metallic scales, generally cupreous

in color, and with short, fairly abundant much inclined pile. Head

rather coarsely, closely punctured; rostrum twice as long as broad,

feebly depressed in front, non-sulcate, with a fine longitudinal

Carina at middle, and separated from head by a shallow trans-

verse impression; eyes much flattened, hardly projecting beyond

side margins of head; the antennas with scape reaching hind mar-

gin of eyes, first and second funicular segments elongate, the fol-

lowing moniliform with the seventh the largest, club fusiform.

Prothorax distinctly broader than long, sides arcuate from base

almost to apex where narrowly but defintely constricted, disk regu-

larly rugosely tuberculate, postocular lobes poorly developed and

finely fimbriate. Elytra not quite a third longer than broad and

about the same degree broader than prothorax, the humeral angles

prominent, the sides of elytra narrowed and sinuate just posteriorly,

strial punctures rather large, well impressed and close together,

each with a small seta, intervals all flattened. Beneath rather

coarsely punctured, the last ventral bluntly carinate. All tibiae

denticulate within. Length 7,5 mm., breadth 3.5 mm.

Holotype (No. 3672, Mus. Calif. Acad. Sci.) a unique col-

lected near Salt Lake, Utah, July, 1927.

This species is intermediate in character between decoratus

and ur sinus having rather rigid setae like the former but fully

twice as long and slightly prominent postocular lobes like the

latter.

Dyslobus blaisdelli Van Dyke, new species

Rather small, somewhat elongate, piceous, upper surface densely

clothed with brown or grayish scales and with moderately long,

rather sparse, erect brown pile, a triangular patch of silvery scales

VAN DYKE— DYSLO BUS

at sides of prothorax extending from middle to base, and silvery

patches on the third, fifth and seventh elytral intervals at summit

of declivity, the scales of the legs also a silver-green. Head coarsely

punctured; the punctures concealed by overlying scales, rostrum

twice as long as broad, separated from head by shallow transverse

impression, depressed but not defintely sulcate at apex and with

narrow and obscure median longitudinal carina; eyes much flat-

tened, protruding but slightly beyond side margins of head; an-

tennal scape reaching hind margin of eyes; first and second funi-

cular segments moderately elongate, the following moniliform with

the seventh slightly larger than the preceding, club fusiform and

about twice as long as broad. Prothorax at least a fifth broader than

long, sides narrowed anteriorly and posteriorly and but slightly

arcuate at middle, disk rather coarsely closely punctured like head

and with punctures concealed by the scales hence more or less

smooth in general, the postocular lobes but poorly defined. Elytra

two-fifths longer than broad and almost a third broader than pro-

thorax in female, narrower in male, humeral angles distinct but not

prominent, the sides of elytra slightly constricted and sinuate just

back of angles, the striae barely impressed and regular punctured

with moderate sized punctures, each with a small seta, the intervals

flat. Beneath rather coarsely punctured and also rugose behind,

the males with first ventral barely sulcate and last ventral evenly

convex, the female with first ventral non-sulcate and last ventral

obtusely carinate. Anterior tibiae distinctly denticulate in males,

faintly so in females. Length 7 mm., breadth 2.75 mm. in males

and 3 mm. in females.

Holotype male (No. 3673), Licking Fork, Tuolumne River,

2900-3100 feet, June; allotype female (No. 3674, Mus. Calif.

Acad. Sci.), Mokelumne Hill, Tuolumne Co., Calif., June, and

four paratypes, Davis Meadow, R. R. Flat, near Mokelumne

Hill, 2800 feet, June, all collected by Dr. F. E. Blaisdell.

The main characteristics of this species are its sparse yet

evident pilosity, smooth pronotum, and very slightly developed

though distinct humeral angles.

Dyslobus bakeri Van Dyke, new species

Of moderate size, somewhat elongate, piceous, head and pro-

notum moderately and elytra densely clothed with variously colored

metallic scales, golden, green, silver or brown, and moderately

setose, the hairs short, black and much inclined. Head coarsely,

closely punctured, the scales in most cases concealing the punc-

tures ; rostrum nearly three times as long as broad, separated from

head by a shallow, transverse impression, depressed in front and

coarsely strigose, with a fine, somewhat obscure median longi-

tudinal carina; eyes rather flattened, projecting but little beyond

side margin of head; antennal scape reaching hind margin of eyes,

THE PAN-PACIFIC ENTOMOLOGIST [yOL. IX, NO. 1

first and second funicular segments elongate, the following monili-

form with the seventh the largest, club fusiform and about twice

as long as broad. Prothorax one-fifth broader than long, sides

rather evenly arcuate from base to apex, disk coarsely, closely

punctured with certain of the punctured areas elevated into pitted

tubercles here and there over the surface, and in general with a

well defined median longitudinal impression, also several shallow

impressions at the sides or in front and back, the postocular lobes

poorly developed. Elytra nearly a third longer than broad, one-

sixth broader than prothorax in male and fully one-fourth broader

in female, humeral angles poorly defined, sides of elytra arcuate

to base, striae hardly impressed but rather regularly and coarsely

punctured, each puncture with a greenish metalic seta, the even

intervals fiat, the odd somewhat convex and generally more promi-

nent especially toward apex. Beneath coarsely punctured, abdo-

men more or less rugose as well, the prostemum with a pronounced

double tubercle posteriorly behind the anterior legs, the males with

abdomen in front shallowly sulcate at middle and last ventral gen-

erally evenly convex, the females with last ventral obtusely cari-

nate. Anterior tibiae distinctly, middle and hind obscurely, denticu-

late, the anterior quite arcuate in front especially in males. Male,

length 8 mm., breadth 3 mm. ; female, length 9 mm., breadth 4 mm.

Holotype male (No. 3675), allotype female (No. 3676),

Mus. Calif. Acad. Sci., and several designated paratypes from

a series of over ninety specimens. The types were collected by

myself at Marshfield, Ore., June 11 and 14th, 1914. Other speci-

mens have been taken at Cannon Beach, Ore., June, 1927; Wal-

port. Ore., June, 1923, (E. P. Van Duzee) ; Crescent City, Calif.,

June 21, 1922; Westport, Wash., Feb. 22, 1932, (W. W. Baker),

and March 20, 1932, (J. Wilcox).

This very pretty, somewhat varicolored species seems to be

restricted to the extreme coastal belt of Washington and Oregon,

extending as far south as Crescent City, Calif. Its most distinc-

tive character is the prosternal tubercle. It could only be con-

fused with wilcoxi, or viridescens among northern species; the

former, however, not only lacks the prosternal tubercle but pos-

sesses well defined humeral angles and has the scales of the

upper surface of a uniform golden color. The latter also has

well defined humeral angles and lacks the prosternal tubercle.

The poorly defined humeral angles and elytra rounded at base

will also assist in separating hakeri from other northern species,

all of which have well developed, generally auriculate, humeral

angles.

VAN DYKE— DYSLOBUS

Dyslobus granulatus (Casey)

This species ranges throughout northeastern California, ex-

tending south along the Sierra foothills as far as Eldorado

County, and overlaps into Oregon. The more northern forms are

generally dark, with few silvery scales and rather long, fine pile.

They link up in the north with ur sinus (Horn) , the latter having

the humeral angles prominently developed. In the southern part

of its range, in Placer and Eldorado counties, the specimens be-

come lighter in color and more highly decorated, the silvery

bands along the sides of prothorax and at the apex of the elytral

declivity being quite conspicuous. The pile of these specimens

is also generally shorter, sparser and more setose. This species

may also become of some economic importance like some of its

northern relatives. Mr. H. H. Keifer took one at Bowman, Placer

Co., Aug. 23, 1931, on strawberry plants.

Dyslobus sordidus (Horn)

Dyslobus (Amnesia) elongatus (Horn) is the male of sordi-

dus. As stated previously, field studies have definitely proven

this.

Dyslobus franciscanus Van Dyke, new species

Small, robust, piceous, densely clothed above with very larg'e,

somewhat obliquely attached scales and moderately long, semierect

black pile, the scales in general dark brown but with silvery scales

forming a broken line at the sides of prothorax and spots at the

sides of elytra and elytral declivity, and black scales arranged in

the form of a median and lateral prothoracic stripes and small

patches on the elytra chiefly about the elytral declivity. Head

closely, coarsely punctured, the punctures concealed by the scales;

rostrum two and a half times as long as broad, separated from

head by a shallow transverse impression; somewhat flattened and

depressed in front; eyes flattened, hardly projecting beyond side

margin of head; antennal scape reaching hind margin of eyes,

first and second funicular segments elongate, the following monili-

form, club about twice as long as broad. Prothorax a bit broader

than long, sides broadly arcuate posteriorly, somewhat less so an-

teriorly and convergent, disk smooth as a result of scaly covering

but when denuded granulo-punctate, postocular lobes poorly de-

fined. Elytra almost twice as long as wide in male and about one-

third longer in female, somewhat wider than prothorax in males

and a third wider in females, humeral angles poorly defined, the

sides of elytra evenly rounded to base, stri^ finely impressed and

finely punctured, each with a minute white seta, the intervals flat.

Beneath coarsely punctured and rugose, the first ventral segment

female. Front tibiaa finely denticulate. Male, length 6.5 mm.,

breadth 2.75 mm.; female, length 7 mm., breadth 3.5 mm.

Holotype male (No. 3677), allotype female (No. 3678),

Mus. Calif. Acad. Sci., and several designated paratypes from a

series of thirty specimens collected on the margins of the sand

dunes near Daly City, a suburb adjacent to the Mission district

of San Francisco, Calif., Mayj 11, 1911.

This rather attractive species I at one time took to be tessel-

latus Casey but Mr. Buchanan after comparison pronounced it

quite distinct. He has also succeeded in having the U. S. National

Museum loan me a paratype in order that I might see the dif-

ferences myself. At first sight the two appear to be the same

species but upon high magnification, the scales of tessellatus are

found to be narrow, small and flatly attached while in fran-

ciscanus they are large, broad and generally obliquely attached,

giving the appearance of an animal with its fur rubbed the wrong

way. It is strange that two sLch closely related yet very distinct

species should be found so near to each other.

Dyslobus dolorosiis Van Dyke, new species

Moderate in size, elongate, black, head and elytra densely clothed

with moderate sized, closely attached very dark brown, almost

black, scales, with here' and there a few patches of silvery scales,

chieflly on the fifth interval posteriorly, the pronotum with a few

minute and scattered setae and rostrum and elytral declivity with

semierect setae of moderate length, legs and underside clothed with

rather fine brown hairs. Head coarsely, rather closely punctured,

the punctures generally concealed by the scales; rostrum almost

three times as long as broad, depressed and shallowly sulcate in

front, coarsely rugosely punctate, a fine longitudinal carina at

middle, and separated from head by a distinct impression: eyes

flattened, hardly projecting" beyond side margin of head; antennal

scape reaching hind margin of eyes, first and second funicular seg-

ments elongate, the following moniliform and transverse, club fusi-

form and twice as long as wide. Prothorax about a fifth broader

than long, sides arcuate, narrowed in front and faintly constricted

before apex, disk coarsely, rugose and tuberculate, the tubercules

here and there minutely punctured. Elytra slightly more than a

third longer than broad and somewhat less than a third broader

than prothorax, humeral angles vague, margins of elytra evenly

rounded to base, striae shallowly impressed but the punctures large,

well spaced and deeply impressed, the intervals flat, declivity almost

vertical but evenly arched at crest. Beneath coarsely, closely punc-

A PRACTICAL METHOD OF CONTROLLING

DENDROCTONUS VALENS LEC,

BY ERIC WALTHER

Golden Gate Park, San Francisco

A recent outbreak of the Red Turpentine Beetle, in Golden

Gate Park, of, at first, rather serious proportions, has now been

brought under practically complete control. Aside from the

usual measures of sanitation, etc,, the following method of saving

individual pines attacked was found to be highly effective. Essen-

tially, this consisted of the injection into the beetle-burrows of

Ethylene-dichloride, whose vapors are highly toxic to all stages

of this beetle, equalling in this respect the dangerous and offen-

sive Carbon-bisulphide, Previous to injecting the liquid, which

was done by means of a one-ounce medical syringe, the rough,

outer bark only was trimmed away with a cooper’s adze. Inci-

dentally this served to remove the exuded resin found at the

entrance opening, which otherwise would soon stop up the tip

of the nozzle. Subsequently all openings, entrance burrow, ven-

tilating holes and all cracks, were stopped up with putty, so as

to confine the toxic vapors.

An experience, now extending well over two years, shows,

first, that the demonstrated efficiency of this method is over 95%,

second, that absolutely no injury to the pines results from the

treatments proper, and last, that this particular beetle- epidemic

has been completely checked, almost in its inception.

We should be glad to furnish any further information de-

sired, on request directed to us at above address, and expect to

publish a more extended statement in the near future.

A NATURE BOOK FOR ENTOMOLOGISTS

Blatchley, W. S. In Days Agone. Notes on the Fauna and

Flora of Subtropical Florida in the Days When Most of Its Area

was a Primeval Wilderness. 12mo. The Nature Publishing Com-

pany, Indianapolis, Indiana. $2.00, postage extra.

It is not given to every entomologist to be both a field naturalist

and a systematist. Rarely can one study the intimate life of the

insect in the field and then experience the joys of the “closet

naturalist”, as the systematist has often been called, as he inves-

tigates the morphological characters of his insects and places

them in their proper relationship with allied forms. To Professor

Blatchley was given this favor and how well he has improved

his opportunities we can learn by reading this most interesting

account of four collecting trips he has taken through Florida.

In speaking of the field naturalist I refer only to what Pro-

fessor Blatchley calls the “old fashioned naturalist” and not to

the collector of insects who goes into the field only on rare oc-

casions and then rushes wildly about chasing butterflies or dragon

flies, beating bushes and trees, or sweeping the grass and weeds,

intent only on corralling the complete insect population of the

district. It is he and his kind that build up the great collections

of insects that become the mecca of the systematists, but he misses

the real joy of the great out-of-doors. It takes leisure as well as

a real love of nature to make a Thoreau or a Blatchley and most

of us must be content to take ours by reading their books. “In

Days Agone” differs from most books of its kind in that it gives

the scientific names of the insect material, so it becomes a very

storehouse of facts for the entomologist interested in the relation-

ship of the insect to its surroundings. For the collector planning

a visit to Florida Professor Blatchley’s book would be the best

guide he could get. I have stressed the entomological features of

the book but it treats of all forms of animal and vegetable life

encountered by the author, insect life being perhaps predominant,

but nothing is neglected that a true lover of nature would observe.

The insects mentioned in the book will be found in the index

under the name of the genus only.

The book is very appropriately dedicated to the author’s two

naturalist associates of earlier days. Dr. David Starr Jordan and

Dr. Barton Warren Evermann, both of whom have finished their

studies and have passed on ahead. — E. P. Van Duzee.

NOTE ON THE RELATIONSHIP OF AN ICHNEUMONID

TO CERTAIN DIGGER WASPS

BY CHARLES H. HICKS

University of Colorado, Boulder, Colorado

The digger waspsf Podalonia violaceipennis (Lep.) and Sphex

xanthopterus (Cam.), have been found fairly common nesting

in the sand of the Los Angeles River. The nesting females have

been studied in the field, their prey with attached egg secured,

brought to the laboratory and development witnessed. In this

way certain parasites and other insects, affecting the young of

these wasps, have been reared. Among these is a large ichneu-

monid, Paniscus sp.', which ravages the food of the wasp larva

and later kills it.

The prey of P. violaceipennis and 5. xanthopterus among

others, consists of Zale lunata (Drury*) and its varieties and

Homoptera salicis Behr, the latter species having been deter-

mined by the late Dr. William Barnes. It is with Z. lunata,

however, that this paper more specifically deals.

The first record of Paniscus, obtained by the author, was

secured from a nest of P. violaceipennis on August 11th, sev-

eral years ago at Universal City, California. The wasp egg was

broken while transporting it and later perished. Little atten-

tion was given to the prey until August 18th when a large, nearly

mature, larva had almost finished eating it. On the morning

of the 19th this larva, to all appearances, had finished a cocoon

which differed in many ways from that formed by the larva of

the wasp, P. violaceipennis. Thick black strandsi held suspended

in the center of the vial measuring 14 mm. in diameter, a nearly

black cocoon. This cocoon measured 16 mm. in length, 6 mm.

in diameter through the center and about 5 mm. at either end.

An adult ichneumonid, a Paniscus, possibly seinirufus, emerged

^ Wasps referred to in this paper have been determined by Professor H. T.

Fernald.

the sun were conspicuous on the mounds. Several were secured,

each of which, with one exception, when opened contained a

dead larva. This one held a live pupa, which was apparently

entirely surrounded with a liquid. The pupa, exposed and re-

moved from the cocoon and liquid, soon died. It is a question

if this substance held any important place under these condi-

tions in the life of the insect.

The ichneumonid was reared also while studying the habits

of S. xanthopterus using like prey. The interesting but serious

relationship, in so far as the young of the wasp and the moth

is concerned, was again observed. The nest and prey, with the

egg of 5. xanthopterus, were taken late on the afternoon of

October 8, 1927, at Los Angeles, California. By October 11th

the wasp’s egg had already hatched and this larva was feeding

from the moth larva. Soon a small larva was found between

the first pair of true legs of the prey.

Each continued to feed without leaving its respective posi-

tion for three days more, during which time the ichneumonid

grew faster than did the wasp larva. On the evening of October

14th, the ichneumonid left its original feeding place at the an-

terior part of the body, moved back and attacked the living wasp

larva. Its head soon became attached to the side, near the cen-

ter of the body, while the attacked wasp larva still held onto

its prey.

The following morning nothing but a limp skin of the wasp

larva remained, the head still at its first position on the fourth

abdominal segment. The ichneumonid was feeding again, at this

time on the remains of the moth larva, the original prey. By

mid afternoon almost all of the moth larva had been eaten with

the exception of the skin and the hard parts of the head and legs.

By evening the parasite had spun a few strands for its cocoon,

which by morning had been increased and supplemented by an

apparently complete cocoon of the insect.

It would be interesting to learn whether or not the wasp

larva ever destroys the larva of Paniscus under the conditions

as outlined above. As far as my observations go, the wasp larva

has always been destroyed and devoured by the ichneumonid.

The number of wasps destroyed each season must be great and

the ichneumonid must constitute a serious menace to its increase

in numbers.

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 2

Cushman in an excellent and interesting account of some

types of parasitism among the ichneumonidae, reviews a number

of records of habits in certain species of the genus Paniscus.

This paper considers parasite and host relationships, the egg of

Paniscus and its development, growth and change in the larva

and other pertinent and important points.

The host, in the instances recorded, has always been a lepidop-

terous larva. He states (p. 40) that: “In Paniscus and very

likely in all the parasites of this type the attack of the parasite

is made on nearly or quite full-grown larvae, which thereafter

burrow into the ground (presumably,) or some other medium

for pupation.”

Edgar A. Dodge

It is with sincere regret that we chronicle the passing of our

friend, Mr. E. A. Dodge of Santa Cruz, California, at the ripe

age of nearly eighty years. Through all his long life he was

actively interested in the study of the North American Lepii-

doptera. During his earlier years he collected at or near his

home at Louisiana, Missouri in collaboration with his brother,

G. M. Dodge. Together they became interested in the genus

Catocala and accumulated a very complete series of the Amer-

ican species of those beautiful moths. With his brother he

also became much interested in the Hesperidae or “skippers”

and in time secured a fairly complete series of the North Amer-

ican species.

Mr. Dodge’s removal to Santa Cruz about 1909 did not lessen

his interest in the Lepidoptera and in his later years, in collabora-

tion with Mr. John Strohbeen, he turned his attention to the

collection of the butterflies and moths of Santa Cruz County,

in which work he was actively engaged up to the time of his

death. His collection, including the valuable material taken

during his early life in the middle west, he left to the California

Academy of Sciences, to whose collection of insects it will make

a most valued addition. — E. P. Van Duzee.

BY FOSTER H. BENJAMIN

Bureau of Entomology,

The notes and descriptions in this paper are the result of

identification of specimens submitted by Mr. J. R. Malloch for

Mr. Owen Bryant.

Five generic and sixteen specific names are discussed, one

specific name is placed in synonymy, four specific names are

placed as representing subspecies, one specific name is removed

from synonymy, and six new species and four new varieties are

described, one of the latter representing a species not hereto-

fore recorded from North America.

Ala picteti Stand.

1882, Staudinger, Stett. Ent. Zeit., p. 49, Ala.

A single specimen labeled “Siberia” is in the National Mu-

seum. The fore tibia bears two long spines near the distal end

with another long spine a short distance above, and the outer

side of the tibia is fringed with exceedingly long hair tending

to droop over and hide the spines. The hind tibia possesses

spines for its entire length. The palpus is relatively long, with

more scales and less hair than that of Archanarta. The antennae

are strongly beaded instead of being serrate or lamellate. The

eyes are reniform shaped and hairy. The fore wing has vein 7

shortly stalked with the stem of veins 8 and 9; the hind wing

has veins 6 and 7 shortly stalked. The habitus is decidedly

Heliothid. The genitalia indicate a very distinct offshoot of

the Anomogyna series.

^ The eyes of Barrovia B. & McD., “Psychorphora” fasciata Skin, only known

species, are sparsely but distinctly hairy, this character usually obscured because

of grease. Probably Parabarrovia keelei Gibson will also be found to have hairy

eyes.

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 2

not only a genitalic affinity, but the possession of hair on the

eyes, a character heretofore overlooked in the genus Anomogyna.

While the hairs on the eyes of specimens belonging to the latter

genus are relatively sparse, the individual hairs are long and

can be discerned without difficulty. Many “agrotids” have obso-

lescent short hairs on the eyes.

From Ala Staudinger Archanarta is distinct not only by dif-

ferences in all the structures of the genitalia, but by the shorter

and more hairy palpi, the weaker spining on the hind tibiae,

and the habitus.

A pair of European specimens of quieta, those discussed by

Barnes & Benjamin, have veins 8 and 9 of the fore wing the

only stalked veins, vein 7 being from the discocellulars well

below the accessory cell; the hind wing having veins 6 and 7

connate.

Archanarta constricta Wlk.

1857, Walker, Cat. Lep. Het. B. M., XI, 701, Anarta.

A single North American specimen from Herschel Island,

Y. T., (Bryant) has vein 7 of the fore wing shortly stalked

with the stem of veins 8 and 9; veins 6 and 7 of the hind wing

shortly stalked. While these characters have usually been con-

sidered as generic by European entomologists they may not, in

the present instance, be of specific significance.

The antennal serrations ( almost lamellations ) are very

slightly heavier on the Bryant specimen than on the European

male of quieta.

Slight differences exist between the genitalia of these two

males, differences which might easily be individual.

Until additional specimens can be obtained for study, the

name constricta may be resurrected for the North American

form, and the name quieta restricted to the European.

Archanarta bryanti Benjamin, n. sp.

Similar in habitus to A. qwieta and at first glance appearing

to be a melanistic specimen of that species. The fore wing is

smoky black powdered with grayish blue, the markings more or

less obsolescent, their position as in quieta; the hind wing has a

bluish white ground color which is almost obscured by fuscous.

Beneath: bluish white, powdered with fuscous which marks the

veins.

Easily distinguished from quieta and constricta by the lack

of spines on the fore tibia, and by the simple ciliated antenna.

APRIL, 1933]

BENJAMIN— NOTES ON PHAL^RRID^

The present species is possibly worthy of generic separa-

tion, but the general habitus of the genitalia suggests a close

affinity to quieta. From both quieta and constricta the geni-

talia differ by having the uncus somewhat more spatulate and

with thinner neck, the vinculum broader basally, and the dorsal

arm of the tip of the harpe shorter than the ventral arm, the

latter character possibly only individual in this group. Ex-

panse, 25 mm. Type locality: Aklavik, N. W. T. Holotype,

male, July 28, 1931, Bryant lot 271, Cat. No. 44311, U.S.N.M.

Anomagyna mallochi Benjamin, n. sp.

Allied to imperita Hubner, with which it agrees in all color and

pattern characters. The genitalia show no differences which can

be considered specific, but the male antennae are much more heav-

ily serrate (or lamellate) than those of the Labrador to Rocky

Mountain species. Expanse, 34-38 mm.

Type locality and number of sex types: Holotype, male,

Aklavik, N. W. T., July 24, 1931; five male Paratypes, same

data; three male Paratypes, Aklavik, July 15, 1931; all taken

by Owen Bryant. Type and three paratypes in U.S.N.M., five

paratypes returned to Mr. Malloch. Cat. No. 44312, U.S.N.M.

Anomogyna mallochi arufoides Benjamin, n. var.

Superficially appearing to be quite a distinct species, but

probably only a melanistic form, as the antennae and genitalia

agree with those of mallochi.

Fore wing smoky, lacking all red tints, and possessing a broad

black band suffusing the outer half of the medial area below the

reniform to the transverse posterior line. Expanse, 37 mm.

Anomogyna mallochi stejnigeri Benjamin, n. subsp.

Possibly a distinct species, but the antennae are so similar

to those of mallochi that a subspecies is indicated.

Fore wing pale chocolate strongly suffused with purple; the

lines and markings similar in shape to those of imperita,; the

transverse anterior line mesially marked by bright purple gray,

the orbicular and reniform strongly suffused with purple, a con-

spicuous purple shading tending to fill the area between the trans-

verse posterior line and the obsolescent subterminal shade. Hind

wing with the pale ground heavily suffused with fuscous brown,

especially distally and on the veins; with a faint discal dot and

Anomogyna speciosa Hbn.

The undersides of the male antennae show lamellations.

North American specimens seem to possess somewhat larger

eyes, as an average, than European examples.

Anomogyna apropitia Benjamin, n. sp.

Male antennae composed of beaded segments, neither serrate

nor lamellate. Male eyes reduced in size, female eyes subreni-

form. Superficially the color and pattern are similar to those

of A. speciosa form arctica Zett., but the wings are duller in tint,

and the body is slighter in build than the speciosa forms. The

genitalia are essentially of the speciosa pattern. Expanse, Male,

37 mm,; female, 43 mm.

Evidently much like the Asiatic propitia Pung., but the anti-

nome of that species in so far as the antennae are concerned.

Type locality: Banff, Alta.

Anomogyna aklavicensis Benjamin, n. sp.

Male antennae very slightly serrate; eyes subreniform; only a

single weak spine was found on the inner side of the fore tibia.

Markings essentially of the speciosa pattern; but the reniform is

more erect and less constricted; the fore wing is dull brownish,

more or less powdered with gray; the hind wing dull fuscous

with obsolescent darker median and terminal shades and discal

mark. The underside as in speciosa but dull, the markings obso-

lescent. Genitalia of the speciosa pattern. The exact shape of

the harpe, clasper, and uncus seems to differ slightly from that

of related species. Expanse, 35-38 mm.

No essential differences were found between the genitalia of

several of the so-called species of the richardsoni group of

Anarta. Slight individual differences in the exact shape of the

claspers and the harpes indicate a variable species.

A male type of richardsoni is in the National Museum having

descended through Doubleday, Guenee, Oberthiir, and Barnes.

Greenland specimens representing a manuscript Bang-Hass name

are of the same form as the type of richardsoni. This is a form

with the fore wing lacking all orange and most of the olive

tints; the disc of the hind wing paper- white, occasionally soiled

with fuscous. The only specimen of European algida in the

Museum is a faded female. This example much resembles the

type of richardsoni. For the present the normal European syn-

onmy will have to stand.

Anarta richardsoni septentrionis Wlk.

1857, Walker, Cat. Lep. Het. B. M., XI, 700, Anarta.

Mr. Tams has examined the first specimen listed by Hampson

(I.C., V, 40) under the name richardsoni, and concerning this

example writes: “The type of M. feildeni was, as you say, en-

tirely missed by Hampson, but I have carefully labeled its type

myself.”

The description indicates a local form related to languinosa.

Anarta richardsoni languinosa Sm.

1900, Smith, Proc. Wash. Acad. Sci., II, 492, Anarta.

This “species” was described from a male from Popoff Island,

Alaska. The type, in the National Museum, represents a sub-

species intermediate between the Arctic America to Greenland

race (richardsoni) and the Labrador race (described herein),

showing some orange powderings on the fore wing, but with

the disc of the hind wing strongly yellowish tinted, not paper

white. Three specimens from Aklavik, N. W. T. (Bryant) show

the hind wings as in the type. The fore wing of one example

matches that of the type; the fore wings of the other two exam-

ples tend to lose the orange scaling and the mossy appearance.

Anarta richardsoni tamsi Benjamin, n. subsp.

This is the Laborador race which is usually called richard-

soni in collections. Both Smith and Bang-Haas appear to have

considered this race a distinct species under the name of rich-

ardsoni. The superficial appearance is that of a distinct spe-

cies. The fore wing is usually heavily marked with orange, or

occasionally the orange may be replaced, wholly or in part, by

strong mossy-green powderings. The disc of the hind wing is

paper white, the broad black terminal band not so cleanly de-

marked mesially as in richardsoni and languinosa. Expanse,

Male and female, 27-35 mm.

Anarta richardsoni squara Sm.

1908, Smith, Ann. N. Y. Acad. Sci., XVIII (2), 112, Anarta.

Described from Greenland. The genitalia, from a cotype

in the National Museum, are so like those of richardsoni that

a variety of that species is indicated. Superficially the colora-

tion and markings suggest the possibility of a valid species.

The fore wing has a dull powdery appearance, with some

orange scaling, and a disconcolorously darker median area;

the hind wing has the disc luteous brown (possibly stained,

presumably not) .

Anarta etacta Sm.

1900, Smith, Proc. Wash. Acad. Sci., II, 493, Anarta.

Judging from the unique female type in the National Mu-

seum, etacta belongs to the richardsoni group. The ground

color of the hind wing is white, but much darkened with fus-

cous; the normal broad black distal band and the black disco-

cellular spots are both absent. The fore wing has the ordinary

markings strongly emphasized by white as in Hampson’s figure

(1905, Cat. Lep. Phal. B. M., V, pi. LXXXVI, f. 4), which

otherwise is not good. A valid species is indicated.

V, (3), 117, Anarta.

Only the two females cited in the original description are

before the author. The species may be distinguished from its

allies in the richardsoni group by the black bar connecting the

discocellular spot with the wing base on the underside of the

hind wing. This character is not duplicated in over three hun-

dred specimens belonging to other species in the same group,

although the type and paratype of magna were collected with a

time interval of some twenty or thirty years. The holotype was

collected at 13,000 feet altitude on Bullion Peak, Colo., by Mr.

George P. Engelhardt; and the paratype, labeled “Colo. Bruce,”

probably came from the same locality.

Anarta preblei Benjamin, n. sp.

Belongs to the leucocycla group, but superficially resembles a

small richardsoni. Fore wing fuscous brown heavily powdered

basal and transverse anterior lines obscured by the black pow-

dering; the orbicular mainly as a bluish white suffusion with

blackish powderings; reniform small, similar to the orbicular but

with noticeable black outlines; cell filled with black; claviform

black, basally continued by two black bars, the interspace olive

green; transverse posterior line black, produced to points on the

veins, excurved around the cell, thence incurved; followed by a

bluish white powdering; subterminal shade black, diffused; a

strong black terminal line of dots extending onto and checkering

the white fringe. Hind wing with the disc white, heavily powdered

with black, which obscures the area from mesad of the strong

black discal spot to the inner margin; an obsolescent powdery

black thin medial line, the terminal third of the wing occupied

by a powdery black band which is intensified into a terminal

line; fringe white. Beneath: Fore wing bluish white powdered

with black scales, with black discal spot, a black spot marking

the transverse posterior line on the costa, and a subterminal

blotchy line; terminal line and fringes as on upper side. Hind

wing much as on upper side but with the bluish white disc more

extended, the terminal band narrower and more suffused, and

with a strong black bar connecting the discal spot with the base

of the wing. Expanse, 27 mm.

Autographa (Syngrapha) INTERROGATIONIS L.'

1758, Linnaeus, Syst. Nat., ed. X, p, 513, Phalsena Noctua.

Two examples labeled “Greenland” ex Oberthiir Collection

superficially appear to be the form called borealis by Reuter,

or are closely allied thereto.

Staudinger’s description of gronlandica indicates a species

with the silvery dentate but erect lines of the u-aureum group.

Aurivillius’ figure and synonymy are probably correct. (1890,

Bihang K. Vet.-Akad. Handl., XV, Afd. IV, No. 1, p. 16, pi. 1,

f. 7).

Hampson’s figure of “ groenlandica’’ (Cat. Lep. Phal. B. M.,

XIll, pi. CCXXXVI, f. 23) is based on a specimen from Ice-

land, and much resembles the form of interro gationis labeled

“Greenland” in the National Museum, differing mainly in the

shape of the stigma and the coloration of the base of the hind

wing.

A series of specimens from Finland, Scandinavia, Iceland,

and Greenland will be necessary to solve this riddle. The geni-

talia of specimens of interro gationis from central Europe are

much like Pierce’s figure (1909, Genit. Noct., pi. XXIX) ; but

the clavus of the Greenland form is somewhat more lobate and

less elongate. Minor differences, which probably are not con-

stant, exist in the exact shapes of the harpes. Lack of material

from Finland and Scandinavia prohibits checking on these

characters.

Autographa interrogationis herschelensis Benjamin, n. subsp.

Superficially differs from mterro gationis (from central Eu-

rope) by having the fore wing suffused with purplish blue-gray.

The reniform is elongate and narrow, so constricted as to appear

almost an elongate figure 8, The U-shaped stigma is tailless, but

distally there is a small silver dot not on a line with the bottom

of the “U,” but opposite the center of this mark. The genitalia

have the clavus similar to that structure in the Greenland speci-

mens, Slight differences exist in the exact shape of the harpe,

known to the author.

and in the clasper, which bears an additional disto-central point

in the present form.®

The present subspecies must be similar to transbaikalensis

Staudinger (1892, Iris, V, 371) from south-central and south-

eastern Siberia, but the hind wings of the North American form

are not noticeably different from those of specimens from Eu-

rope, the fore wings possess the disconcolorous medial areas,

and the shape of the stigmae appears different. Expanse, 38 mm.

Insect Notes

The following observations are from the files of the State

Department of Agriculture:

Paraneura simulella Dietz. This Tineid, which superficially

resembles the CEcophorid, Borkhausenia pseudospretella Staint,

has been reared from Tulip Bulbs. The moth itself is not un-

common in California.

Homoeosoma electellum Hulst. What Heinrich thinks may

be variety opalescella Rag., appeared in quantity throughout the

lower Sacramento Valley in 1932. Larvse were quite injurious

to sunflower heads in several localities. Previous to 1932 no

individuals could be easily found.

Andrena flavoclypeata Sm. We have had this bee submitted

a number of times from Sacramento lawns. The adults are ac-

tive in March and may be very locally numerous, piling up many

small mounds of earth throughout the grass. — H. H. Keifer, De-

partment of Agriculture, Sacramento, California.

® The two latter characters may have little or no significance. They are noted

because they exist in the unique type.

VAN DUZEE— FIVE DIPTERA

Of four species with third antennal segment formed some-

what alike, Wheeler described emarginatum, which has a dis-

tinct subapical offset on both upper and lower edge, between

which projects the rather slender, acutely pointed tip, the arista

being inserted above near the tip at the offset. Two males of

emarginatum were taken at Saltair with these utahnum. Curran

described emarginaticorms from Alberta having the first two

antennal segments yellow below, third twice as long as wide and

distinctly concave at tip, and later longicornis Van Duzee was

described from Oregon, with only first antennal segment yellow

below on apical half, third segment three times as long as wide,

slightly oblique at tip, with the arista at basal fourth. The

present form has the antennae wholly black, third segment three

times as long as wide, apex with a small V-shaped notch in the

middle, and the arista at the middle of upper edge.

two antennal joints yellow, third black or dark brown; coxae,

femora and tibiae wholly, and tarsi mostly, pale yellow; tarsi

plain; first two abdominal segments wholly yellow in the male,

in the female the first and basal half of second segment yellow;

sent me at the time he described it, I am quite sure these all

belong to his species although there seems to be considerable

difference in the measurements of the joints of the tarsi.

The following characters were not mentioned by him in his

description and are common to the specimens in the Buffalo

Society collection and the one specimen sent me by Mr. John-

son. The first three joints of fore tarsi each have two long

hairs at tip, the first with seven other long hairs; wing veins

largely yellow, especially the second and third veins; last joint

of both front and middle tarsi distinctly widened. In the male

in the Buffalo Society collection the length of front tibiae is as

52, of middle as 65 and of posterior as 80; joints of fore tarsi

as 17-9-8-7-8; longest hairs on first joint as 10; joints of middle

Engytatus geniculatus Reuter

On August 17, 1931, Mr. A. C. Browne, of the State Depart-

ment of Agriculture, found evidence to indicate that this Mirid

produced a peculiar injury on tomato stems in the Whittieir dis-

trict. This injury was in the form of a node-like swelling which

had apparently been repeatedly punctured in a circle around

the stem. The conducting tissue showed considerable corrosion

and a small amount of pressure would cause the stem to break

at this point. A little later in the year, a similar injury was

noted in tomato plants and correlated with adults submitted from

Ventura County. This species, while of a different genus, is

rather close to the Tobacco Suck Fly [Dicyphus minimus Uhl.)

AGLAIS CALIFORNICA IN CALIFORNIA DURING 1932

The California Tortoise-shell Butterfly is well known to have

periodic cycles of abundance, one of which occurred recently.

There are reports of numbers in southern Oregon and extreme

northern California in 1931. I observed great numbers in the

northern Sierra Nevada from the Truckee road to the vicinity

of Lassen Peak, July 6 to August 1, 1932. Numerous larvae

were noted July 6 near Bowman Lake, Nevada County, on a

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 2

thicket of Ceanothus. During the ensuing week in this general

vicinity and in southern Sierra County the species was not much

in evidence. Small numbers of the butterflies were noted along

a road south of Sierraville on July 18. The caterpillars and

their work was conspicuous in Plumas County about 15 miles

west of Blairsden on July 19. On succeeding days near Gibson-

ville I saw areas, several acres in extent, of Ceanothus velutinus

which had been entirely denuded of foliage by the larvae so

that only the massed stems of this shrub were seen, giving a

general brown effect. During the remainder of the month the

butterflies were increasingly common from this region north to

Lassen Volcanic National Park. Roadways were often heavily

dotted with them and the radiators of passing automobiles were

well covered with butterflies. Damp soil beside the road at

times was fairly black with resting butterflies showing the under

sides of their wings. In Lassen Park there was a constant drift

of butterflies fairly close to the ground, during the warmer hours

of each day. In the forest near Upper King Creek Meadows on

July 29 I estimated 600 per minute were passing through a sec-

tion 10 feet high between two trees about 50 feet apart. Damp

soil on trails often had 10 to 20 resting butterflies per square

yard. On the trail up Mount Lassen on July 30 but few butter-

flies were seen in the earlier hours (a cold s.w. wind blew all

morning) ; by 10 a. m. they were in evidence and by 10:30 a. m.

they were streaming up the east slope in myriads. At the sum-

mit they were carried here and there by the erratic gusts of

wind and some came to grief on the snow. In general, the di-

rection of drift varied according to slope exposure and the pre-

vailing wind, although there seemed to be a tendency to move

southwesterly. On the Humboldt Road from Lake Almanor to

Chico, August 1, the species was encountered in numbers down

near to Jonesville, Butte County. Throughout my contact with

the species I did not observe any tendency for birds to feed

especially upon it, as was noted by H. C. Bryant at Sisson in

1911 (Condor, 13, 1911, pp. 195-208). — Tracy I. Storer, Di-

KNIGHT— CALOCORISCA

CALOCORISCA CALIFORNICA N. SP., AN ADDITIONAL

GENUS FOR THE UNITED STATES

(Hemiptera, Miridae)

BY HARRY H. KNIGHT

Iowa State College, Ames, Iowa

The genus Calocorisca Distant was described^ to include four

species, all of which were figured. This was a fortunate circum-

stance since I find the figures more helpful than the abbreviated

descriptions. Calocorisca villosa, tenera and antennata were

from Guatemala, while C. thoracica was recorded from Costa

Rica. Later, in the same volume. Distant (1893, p. 439) de-

scribed two more species, C. tenebrosa from Mexico, and C.

chontalensis from Nicaragua. Reuter' described Calocorisca

csneoinduta from Venezuela and gave a redescription of the

genus which is more complete and useful than the original by

Distant. The original description is misleading in speaking

of the scutellum as “apex globosely suberect” for the figures do

not show it, and the writer agrees with Reuter in stating that the

scutellum is only very slightly convex on the apex. Following

a study of the figures of Distant’s species and the description

of the genus by Reuter, I am convinced that the California

species before me should be referred to Calocorisca Dist. No

member of this genus has heretofore been recognized from the

United States, hence it is of particular interest to describe a

new species from California.

Calocorisca calif ornica Knight, new species

Allied to tenera Dist. as indicated by the slightly clavate

second antennal segment; distinguished by the short third and

fourth antennal segments which taken together just about equal

Lampethusa anatina Distant. I have examined specimens of

what I take to he this species, from Texas, Nicaragua and the

Canal Zone. It is distinguished from the above new species by

the larger size, the length of first antennal segment distinctly

greater than width of head across eyes.

Insects at the California Academy of Sciences

The Department of Entomology of the California Academy

of Sciences is maintaining a steady growth. Forty-five thou-

sand specimens were added during 1932, the largest single item

being the Millard C. Van Duzee collection of Diptera. This

collection was largely of species of the eastern United States, a

fauna but poorly represented in the Academy collection. It is

especially strong in certain families generally but imperfectly

represented in collections, such as the Tipulidae, Mycetophilidae

and DolichopodidaB, in the latter family being one of the most

complete in the country. The total number of mounted speci-

mens now in the Academy collection of insects is 925,000. — E. P.

COTTLE— ARGYNNIS BEHRENSI

ANOTHER RARE BUTTERFLY

BY JAMES EDWARD COTTLE

Haywcird, California

The flattering success which crowned my collecting trip of

July, 1931, upon which I located some of the more rare butter-

flies, determined me this July, 1932, to search out a species over

which for a long period much confusion has arisen. I refer to

Argynnis behrensi.

In many collections I have noted Argynnis labeled “Behrensi,”

but not a specimen corresponded in detail to the Argynnis

behrensi pictured in Edward’s works on Lepidoptera, nor did

they tally with descriptions which this famed entomologist gave

of them.

Accompanied by the Rev. Edward Guedet, my companion of

many previous collecting trips, I journeyed this time to the fog-

kissed cliffs and sea-washed shores of Mendocino County and

on to Mendocino City, arriving there July 3rd to find King Fog

supreme in high command. Meals likewise elevated as to price,

beds scarce, with slim chances at the auto camp for parking

even Corpus delicti. Finally we secured two rooms at a private

house.

As the sun appeared we donned our hunting garb and pro-

ceeded to the Point, a strip of land extending from the city to

the ocean for approximately half a mile. The devastating hand

of Man was here everywhere in evidence. Trees, shrubs, flowers

and all verdure had been erased and fields of grain grew in

their place. Thus The Point yielded nothing, our two days lost

we packed our paraphernalia and started down the coast for

Point Arena, Mendocino County, where clouds and dense fog

obscures the sun five days a week.

Here we put up at an auto camp cabin and made inquiries

for a tile camp; our instructions being to follow a canyon which

ran through the town for about four miles toward the moun-

tains. We were told that fires had burned over this section no

less than three times in the last decade, wiping out, of course,

all traces of the camp in question.

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 2

Starting up the canyon we were beset on every side and at

every step by as fine and large a growth of volunteer nettles as

I have yet encountered. We hunted this canyon for two days.

Finally on the third day we ascended the hills where I netted

some specimens of Talides {Polites Auct) sonora, form siris.

Edw. and here it was upon this hillside that one of the strangest

freaks which coincidence has ever played in my career occurred.

As my companion, the Rev. Edward Guedet called to me, I

thought I heard the sound of laughter. So real and so pro-

nounced was it that I paused and listened, but it was not re-

peated. Father Guedet and I were alone on the hillside. Then

in the silence which nature gives to these secluded slopes the

thought occurrd to me: “Could it have been the voice of old

Jim Behrens himself, for whom the butterfly we were hunt-

ing had been named?” Old Jim Behrens, laughing at us from

illimitable space. Reaching the Reverend Father I found him

imprisoning two specimens just caught, in his poison jar, a pair,

a male and female, of Argynnis hehrensi. Our goal was reached,

we captured in all nineteen specimens. Since we had located

them, could we have remained another day we would have taken

many more specimens, but conditions at home necessitated our

departure next day.

Strange world, and stranger still the unsolved mysteries of

the human mind. That mystic attribute had brought the old

collector’s name to me at the very moment when the butter-

flies named for him were being captured. Can it be possible

that the old fellows, Behr, Rivers, Mueller, those who have

tramped the trails we trod, with net in hand are guiding our

footsteps to where long lost specimens may be found? I wonder.

And I wonder also, if when I am doing my collecting in

another sphere, I shall be given the power to guide the younger

feet which follow mine along the trails I’ve trod, to laugh at

them as old Jim Behrens laughed at me, and lead them from

my unseen hunting grounds into the vale of nettles we passed

through? That’s when I would laugh.

INGHAM— NEW BUTTERFLIES

TWO NEW CALIFORNIA BUTTERFLIES

(Lepidoptera, Rhopalocera)

BY CHARLES H. INGHAM

Los Angeles, California

Ascia beckerii Edw. gunderi Ingham, new tr. form

Both upper and under sides showing the black cell spot on

primaries fused outwardly, as well as inwardly, along the confines

of the veins of the cell area; the extremities of the black fusing

forming elongated points which extend half the length of the spot

itself beyond its usual confines. An extra and separate dash

appears at the junction of the median vein and the median nervule

No. 1, this dash pointing inward, and being more pronounced on

the under surface. The white center of the spot in the discal

cell of the primaries present as in typical specimens, all other

markings, including the green design of the under side of the

secondaries normal. Similar in appearance, but not so well de-

veloped to P. daplidice L., tr. f. rondoui Obth., as illustrated in

Rhopalocera Palaearctica by Dr. Roger Verity, plate XXX, figures

12 and 13.

Transition form classification: melanifusism, the final degree

for this species being at present unknown.

Holotype $ ; expanse 35 mm. ; Bouquet Canyon, Los Angeles

County, Calif.; from larvae, emergence date June 21, 1932. Bred

from larva by author, and not subjected to any special environ-

ment. Type deposited in the Type Collection of the California

Academy of Sciences at San Francisco, Calif.; named after my

very good friend, Mr. Jeane D. Gunder of Pasadena, Cali-

fornia, whose classification of lower lepidopterous concepts is

appreciated.

Anthocharis sara Bdv. gunderi Ingham, new race

For several years it has been rumored that a new race of

Anthocharis sara was to be found on the islands off the coast

of southern California, and from Santa Cruz Island in par-

ticular. In March of this year a trip was taken by the author to

Santa Catalina Island and a small series of these was taken,

also other specimens were received by me from two resident

collectors. From study of this series, and comparison with hun-

dreds of Anthocharis sara, and forms of sara taken in Cali-

fornia, Arizona, Utah, and Washington, this race, in my opinion,

is constant and different enough to deserve special designation.

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 2

Race gunderi is smaller than our common race reakirti. (Most

West Coast collectors rank reakirti as a race, rather than a sea-

sonal form.) In size, they are as small as typical reakirti taken

in Chino Canyon and Whitewater Canyon, Riverside County, Cali-

fornia. On the upper side, the males have an unusually heavy

black bar below the apical patch, the outer marginal black spots

on nervules of the secondaries are also strongly marked. In both

sexes, the greenish- black marbling on the under side of the sec-

ondaries dense, and evenly distributed, being heavier than in

reakirti As in all races of sara, the females of gunderi show the

greatest divergence. The apical area around the orange spot is

unusually black in the female of this race, this being caused by

the submergence of the short row of white spots just above the

orange spot, there remaining mere indications of white points,

also the black extends down to the inner angle of the primaries,

and is strongly developed. This feature of the dark apical area

will serve to distinguish this race from others, and the small size

is also a factor. On all of the females of my series, the sec-

ondaries were flushed with a greenish-yellow tinge, not the usual

yellowish colors as in reakirti. This race of sara should be

placed next to reakirti in all future check lists.

MILLS AND ROLFS— COLLEMBOLA

COLLEMBOLA FROM THE STATE OF WASHINGTON

BY H. B. MILLS and A. R. ROLFS "

The Collembola of the Pacific Coast have been studied thus

far mainly by Schott (1891, 1896), Bacon (1912-1914) and

Folsom (1913, 1916, 1917), although isolated species have been

described by MacGillivray (1893, 1894), Canby (1926), and

Mills (1931, 1932).

In this paper is included a rather comprehensive list of

species collected at and about Yakima, together with a few col-

lections from Western Washington, and scattered references in

the literature to collections in the state.

The list, we believe, is quite representative. However,

species of certain genera (Orchesella, Sira) are conspicuous in

their absence. One should look for others of Bacon’s and

Schott’s species described from California, and several additions

to the list should result from collections between tide marks

on the coast.

A number of species seem to be typical of and restricted to

the west coast. Other cosmopolitan forms {Entomobrya multi-

fasciata Tull, and Achorutes armatus Nic.) are abundantly

represented here as they are in any etxtensive collection.

We have been very kindly allowed to examine Dr. Folsom’s

forthcoming monograph of the Isotomidae of North America,

and a number of determinations have been made from his

manuscript.

A total of 63 species and varieties distributed in 23 genera

are recorded.

Achorutes armatus Nic. Yakima, February 20, 21, 23, October

23. Under decaying vegetation and on soil.

' In this paper all determinations were made by H. B. Mills and all collections

by A. R. Rolfs, unless otherwise stated.

THE PAN-PACIFIC ENTOMOLOGIST [vOL. IX, NO. 2

Achorutes maturus Fols. Yakima, February 19-23, March 16, 23,

24, April 5, 11, 19, August 23, October 22, November 1, 15,

tation and under rocks.

Achorutes pseudarmatus Fols. Yakima, March 22; Port Orchard,

October 27 (W. W. Baker). Under rocks and dung at an

elevation of 3000 ft., and among decaying potatoes.

Achorutes socialis Uzel. Lake Tipsoe, October 11. Under boards

and sticks near water, at an elevation of 5400 ft. This species

is primarily a spring form, and its occurrence in October is

interesting. The elevation at which it was taken may have

some bearing on its appearance.

Xenylla baconce Fols. Puyallup, April 25. Under leaves and

moss-covered sticks.

Xenylla humicola (Fab.) Tacoma, April 26. On the surface of

stale pond water. The anal spines in the specimens examined

were sufficiently long to cast some doubt as to the identity

of the species. They were compared with specimens of X.

humicola from Greenland which were received from Mr. J. R.

Denis, and in all points, save the length of the anal spines,

they are comparable.

Xenylla maritima Tull. January 23, October 22. In greenhouse

and under boards.

Willemia anophthalma Borner. Yakima, January 23. In green-

house. This species, represented by the typical form, is

here reported for the first time from North America. It is

a rather widely spread humus form in Europe and England.

Willemia denisi Mills. Yakima, February 23. In leaf mould.

This species is the second to be described in the genus

Willemia. It has been recorded thus far only from Yakima.

Subfamily Neanurin^ Borner

Friesia claviseta Axelson. Yakima, February 23. Under boards

and sticks near water.

Pseudachorutes complexus (MacG.) This species was described

from Washington by MacGillivray (1893).

Neanura muscorum (Temp.) Yakima, April 18, September 6, 7.

In rotting wood and under damp leaves.

Onychiurus armatus (Tull.) Yakima, February 20. Under boards.

Onychiurus subtenuis Fols. Yakima, April 18; Puyallup, Novem-

ber 11 (S. E. Crumb). In and under decaying wood.

Onychiurus cocklei (Fols.) This species is recorded from Wash-

ington by Folsom (1917). It seems to be a typical western

Idaho, but it is not represented in the material studied.

Tullbergia collis Bacon. Yakima, September 7. Under stones

imbedded in wet sod.

Tullbergia iowensis Mills. Yakima, January 23. In greenhouse.

?Isotomodes productus (Axels.) Linnaniemi. Yakima, April 5.

A single specimen of this genus is assigned tentatively to

this species. It was accidentally destroyed before it could

be completely examined, but it agrees quite well with the

figures given by Linnaniemi (1912).

European S. myrmecophila (Rent.) in the number of eyes.

The unguis of the former differs from the figure of Lin-

naniemi (1912) for S. myrmecophila in being longer and

more slender, and of different dentition.

Sinella sexoculata (Schott). Yakima, February 19, 20, April 11,

Entomohrya griseo-olivata (Pack.) Yakima, March; Puyallup,

March 16, April 11, 19, September 6, 7, 20, 22, 23, 25,

November 1. Under sticks, stones, leaves, decaying vegeta-

tion, codling moth bands, and swept from grass.

Entomobrya atrocincta Schott. Yakima, April 15, September 17,

October 25. Under wood, loose bark, and swept in a net

from grass and weeds. Specimens of this species agreeing

with Schott’s figures and meager description seem to be

structurally identical with E. pseudo per pulchra Mills. It

seems altogether possible that both of these species are

synonymous with E. perpulchra (Pack.) The falcate mucro

of the perpulchra type (Mills, 1931, p. 7) may have been

an abnormality, for the species seems to agree in all other

respects with atrocincta and pseudo per pulchra. A fourth

species, E. clitellaria Guthrie, is also close to perpulchra’,

but until a more detailed study of these two can be made, it

will be best to keep them separate.

Entomobrya multifasciata (Tull.) This species formed the bulk

of the material examined, being represented in almost every

A NEW BUPRESTID FROM BRITISH COLUMBIA, WITH

NOTES ON THE GENUS BUPRESTIS^

BY RALPH HOPPING

Vemon, B. C.

The genus Buprestis presents a number of problems subse-

quent to the excellent and comprehensive review of Nicolay and

Weiss". One species has been described since 1918 by H. E.

Burke*, one of Col. Casey’s species appears to be a perfectly

good one and another will be described in this paper. The new

species herein described seems to be quite rare. I have waited

nearly eight years to collect the six specimens now before me.

The notes and conclusions set forth are the result of nearly forty

years collecting in which I have endeavored tO' have each species

represented by a large series. Of late years we have been able

to obtain a more comprehensive view of the distribution of our

species from east to west. The characters are so variable in

many species that a large series is necessary in order to obtain

a comprehensive idea of the limits of variation.

Buprestis contortae Hopping, n. sp.

Length 15-18 mm., only moderately convex; dorsal surface

bluish green with margins of elytra narrowly bronzed; mod-

erately shining; ventral surface bronze-green.

Head densely, coarsely punctured with sharply defined occipital

line; pronotum coarsely, moderately punctured with rather faint

broad median sulcation, side margins arcuate, basal margin bi-

sinuate with basal angles acute ; prosternum broadly sulcate, elytra

distinctly wider than base of pronotum with six entire cost®, one

to four with narrow intervals which in the scutellar area have

large uniseriately placed pits or punctures, especially in the in-

terval between the short scutellar costa and the suture, apices of

elytra rounded to the suture; ventral segments very sparsely and

finely punctured, first ventral sulcate, last ventral broadly arcuate

on apical margin.

HOPPING— A NEW BUPRESTID

Allotype, female, same data. No. 3267 in the Canadian Na-

tional Collection.

Paratypes, 2, same locality, one July 8, 1923. (R. Hopping) ,

and the other June 30, 1926, (W. Mathers), in the Vernon Labora-

tory Collection.

Two other specimens, evidently the same species, from Oliver

and Kimberley, B. C., are not quite typical as the prosternal

process is not or only faintly sulcate.

This species may be separated from intricata Csy., aurulenta

Linn, and adjecta Lee. by the number of costae and the large in-

tercostal pits of the scutellar area.

The four species may be separated by the following key:

A. Elytra with four costae, all the intervals broad and irreg-

ularly punctured, costae not punctate aurulenta Linn.

AA. Elytra with more than four costae, costae punctate.

B. Tips of elytra emarginate and usually bidentate, form

short, robust and convex; elytra with eight costae

adjecta Lee.

BB. Tips of elytra rounded to the suture, form feebly convex.

C. Elytra with eight entire costae intricata Csy.

CC. Elytra with six entire costae contortse n. sp.

Buprestis intricata Csy.

An examination of Casey’s type has convinced me that this

species is entirely distinct from adjecta Lee. It has not the

robust form of adjecta of which I have 16 examples before me.

The punctation of the head and thorax is much coarser and

sparser, the elytra are not so convex and do not represent the

brilliant shining effect of adjecta. The apices of the elytra are

not bidentate or emarginate as in adjecta.

I have one specimen taken at Mt. Mitchell, Tulare County,

California, at 10,000 feet elevation. Casey’s type is bluer than

my specimen.

Buprestis rusticorum Kby.

I have before men 122 specimens of this species, ranging

from British Columbia to California and the southwest, and

have compared these with 29 specimens of B. maculativentris

Say in my collection and a large series in the Canadian, National

Collection. Mr. Blair of the British Museum also very kindly

THE PAN-PACIFIC ENTOMOLOGIST

[VOL, IX, NO, 2

compared a specimen of rusticorum with Kirby’s type. Not

only is rusticorum on the average very much larger than macu-

lativentris but I find the following differences:

Elytra strongly costate, with intercostal spaces of the disc

confusedly punctate, wide, with costee narrow and sharply

defined rusticwwm Kby.

Elytra feebly costate, intercostal spaces of the disc more or

less uniseriately punctured, narrow, with costae more or

less fiattened maculativentris Say.

The length of maculativentris 14-20 mm. and of rusticorum

15-23 mm. given by Nicolay and Weiss, is rather misleading

considering that one rarely finds the former as large as 20 mm.

and the latter as small as 15 mm. A series of maculativentris

averages about 16 mm., and rusticorum 20 mm., with specimens

of the latter 22 and 23 mm. not uncommon.

W. J. Chamberlin in his published notes" remarks that macu-

lativentris can always be told from rusticorum by the spines or

teeth on the tip of the elytra. This is generally true, although I

have found many exceptions, where the tip was perfectly smooth,

showing no sign of tubercles or teeth. The western phase,

subornata Lee., in the small series before me, has the teeth.

In view of the above characteristics, the average size and the

ease with which it may be separated from maculativentris, rusti-

corum in my opinion should be considered a distinct species. The

variety subornata is apparently the western phase of macula-

tiventris.

Buprestis langi Mann.

I have before me 58 specimens of Buprestis langi Mann, and

41 specimens of B. fasciata Fab. of both sexes. I have also

examined a large series of both species in the Canadian National

Collection. Nicolay and Weiss® very excellent descriptions will

serve to separate them easily. Aside from the differences in the

key I find that the generally more elongate form in langi with

the more abruptly rounded margins of the elytra in fasciata also

is very variable in both species, the females of fasciata seem

to be always maculate while as a rule the females of langi

are immaculate. B. fasciata is supposed to breed in maple

HOPPING— A NEW BUPRESTID

and poplar and Dr. Van Dyke gives the host of langi as

Douglas fir. Dr. Burke also writes me that he took all

stages from the same host. Evidently it is not the only host,

as many of my specimens have heen taken on willow in Southern

California at least 300 miles from any Douglas fir. In British

Columbia, in all our cage experiments with Douglas fir, where

whole infested trees have heen caged, we have never hred langi,

although the trees have been caged for several years.

The differences between langi and fasciata may be a little

more definitely expressed by the following:

Elytral strise moderately deep, punctures small; costse broad

and flattened fasciata Fab.

Elytral striae deep, punctures large; costae narrow, not flat-

tened langi Mann.

I have failed to find any difference in the lustre of the costae

or intervals as stated by Nicolay and Weiss. Occasional dull

specimens occur in both species. I have one langi entirely black,

not shining. Melanie forms are not uncommon in the Buprestidee

as I have a specimen of B. aurulenta which is also entirely black.

Mr. Chamberlin in his notes above referred to (p. 94) gives

some differences between the species langi and fasciata especially

in form, which is entirely correct from my observations. But in

regard to colour and maculation no definite rule can be laid down

for either sex. Some of the males of langi seem fully as deserv-

ing of a varietal name as B. lineata var, davisi N. and W. The

general scheme of maculation between the females, however,

show the difference as explained above.

As the specific differences seem exceedingly well defined for

this genus I consider langi a distinct species.

Buprestis nuttalli Kby. var. alternans Lee.

and var. consularis Gory.

I have before me 58 specimens of this complex, from both

the east and the west, and have examined a large series in the

Canadian National Collection with wide distribution. There is

every conceivable elytral maculation from the transverse bands

to specimens with two small dots and with elytra entirely black.

While some typical examples, both east and west, can be sepa-

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 2

rated, the intermediate forms could be made into many sepa-

rate varieties. The elytral intervals “alternately strongly con-

vex” or “strongly convex” is variable and cannot be depended

upon. There is every grade between “thorax sinuate or par-

allel” and “sides of thorax arcuate.” The specimens so gradu-

ally merge from both varieties to nuttalli and the punctation

of the abdomen is so variable between males and females that

they cannot be separated. I therefore consider them one and

the same species and that these varieties cannot be maintained.

Nicolay and Weiss have already intimated that the var. alternans

is the same as nuttalli. Typical examples of what is called con-

sularis are often taken in British Columbia, and we have bred

several from Pinus ponderosa, but as the other forms and inter-

grades are also taken here we cannot separate the series. Appar-

ently the alternately convex intervals vary with the individual.

Mr. K. G. Blair of the British Museum very kindly compared

for me two specimens of nuttalli with Kirby’s type.

A NEW SPECIES OF HELOPS FROM GUADALUPE ISLAND

(Coleoptera: Tenebrionidse)

BY FRANK E. BLAISDELL, SR.

Stanford Medical School and California

Academy of Sciences

Contributions to the knowledge of the Coleoptera of Guada-

lupe Island have been made from time to time. Dr. Geo. Horn

in 1875 gave a list of a small collection made by Dr. Edward

Palmer (Trans. Amer. Ent. Soc., V, 1876, p. 198). A single

species of Helops being listed. Dr. Horn was not certain as to

its specific status, recording it as Helops bachei Lee., var. In

the Canadian Entomologist, vol. XXIX, 1897, H. C. Fall lists

the known species of Coleoptera of the Southern California

Islands, including those of Guadalupe Island, without adding

any species to those reported by Dr. Horn, nor did he make any

comments regarding the specific standing of Helops bachei Lee.,

var. In 1890, Col. Casey described Helops guadalupensis n. sp.

(Ann. N. Y. Acad. Sci., vol. V) and evidently tlhe one referred

to by Dr. Horn. I consider it distinct from bachei Lee.

In 1922, the California Academy of Sciences sent an Expe-

dition to the Island. Among the Coleoptera secured was a series

of guadalupensis taken by Mr. J. R. Slevin. No additional

APRIL, 1933]

BLAISDELL— A NEW HELOPS

species of Helops was collected at that time. The species de-

scribed below makes a rather unique addition to the genus and

one that contrasts greatly with guadalupensis Casey.

Helops crockeri Blaisdell, n. sp.

Form elongate ovate, somewhat slender, head and pronotum

relatively small; surface smooth, feebly sculptured. Color rufous,

legs and under surface of body rufo-testaceous, outer four an-

tennal segments fuscous to piceous.

Head as long as wide, sides arcuately prominent over the an-

tennal insertions, beginning at base of the eyes, thence moderately

convergent and arcuately emarginate to the narrowly rounded

angles of the epistoma, the latter transverse and truncate at apex ;

labrum transverse, twice as wide as long, with sides and angles

evenly arcuate, apex feebly and broadly emarginate, surface mod-

erately finely punctate and sparsely pubescent; frons feebly con-

vex, broadly but not deeply impressed between the antennal con-

vexities and epistomal plane, surface coarsely punctate, becom-

ing rugoso-punctate on vertex and tempora, where the punctures

become more or less coalescent. Eyes obliquely transverse, narrow

and strongly convex, moderately prominent, facets of moderate size

and convexity, tempora not more prominent than base of the eyes.

Antennae long and slender, extending two or three segments beyond

the pronotal base, outer four segments somewhat incrassate; seg-

ments nine, ten and eleven equal in length and twice as long as

wide, third twice as long as the second and about a third longer

than the fourth ; fifth and sixth subequal in length and about twice

as long as wide; seventh as well as the eighth slightly longer than

the ninth, eleventh oblong oval, obliquely pointed at tip.

Pronotum about three-eighths wider than long, apex truncato-

arcuate in moderate circular arc, angles rather broadly and evenly

rounded; sides moderately arcuate, basal angles less broadly

rounded; base moderately arcuate, as wide as the apex; basal bead

flat and rather coarse, the lateral fine, apex not beaded ; disk evenly

but not strongly convex, densely rugoso-punctate, punctures more

or less subcoalescent in twos to fours, central area less rugose.

Elytra oval, about three-fourths longer than wide, about three

times as long as the pronotum; sides moderately and evenly arcu-

ate, converging more toward base than toward apex, rather more

strongly so and arcuately convergent apically, apex subparaboli-

cally rounded; humeri absent, disk strongly and subcylindrically

convex, striae of unimpressed punctures, the latter small and sepa-

rated by a distance equal to four or five times their diameter; in-

tervals very finely and sparsely punctured. Scutellum short and

subhastate.

Propleurae rugoso-punctate, punctures not strong, rugae dis-

90 the pan-pacific entomologist [voL. IX, NO. 2

tinct and irregularly longitudinal. Prosternal process arcuate be-

tween the coxae.

Abdomen finely and sparsely punctate, more or less feebly

rugose laterally; segment five equal to the post-coxal part of the

first, third about a half longer than the fourth, second about a

sixth longer than the third. Legs slender; tarsi not dilated. Edea-

gus exposed. Described from the female holotype.

The male allotype is similar to the female, but more slender;

antennae longer, segments eight, nine and ten equal in length,

three times as long as wide; eleventh a third longer than the tenth

and three times as long as wide. Protarsi and mesotarsi dilated

and pubescent beneath. Abdominal segments three, five and post-

coxal part of the first quite equal in length; second about a third

longer than the fourth.

Measurements: (Types) Length 8 — 9.5 mm.; width 3 — 4 mm.

Holotype, female, No. 3685, and allotype, male. No. 3686,

in the collection of the California Academy of Sciences. Col-

lected at the south end of Guadalupe Island, November 16, 1931,

by J. T. Howell. I take pleasure in naming the species after

Mr. Templeton Crocker, to whom the Academy is indebted for

the opportunity of collecting on the Island.

Crockeri differs from the other species known to inhabit

Guadalupe Island, by its rufous color, smooth surface and

feeble elytral sculpturing and dull luster.

Guadalupensis Casey is of a more robust habitus, more piceous

in color and the sculpturing stronger, the strias of the elytra be-

ing impressed and the form not so ovate, the head and pronotum

being relatively larger. Benitensis Blais, is from Middle Benito

Island and is strongly sculptured, the pronotum densely and

moderately coarsely punctate, the elytra striato-subcostate, the

propleurae densely and distinctly moderately coarsely punctate

and the form is more parallel.

A Word From Dr. Van Dyke

The latest communication received at the Academy from Dr.

E. C. Van Dyke was from Cairo, Egypt. He was planning to

do some collecting in Egypt and then go on to Algeria for more

field work. He expects to be at the British Museum through

most of May, reaching Cambridge, Massachusetts, early in June.

He reports an interesting and profitable trip, much of his time

having been spent studying at the British Museum and at other

of the large museums of Europe. — E. P. Van Duzee.

HILTON— NEW WHIP-SCORPION

A NEW WHIP-SCORPION FROM CUBA

BY WILLIAM A. HILTON

Department of Zoology, Pomona College

In using the genus Schizomus Cook, I follow Hansen who dis-

tinguishes this from the genus Trithyreus although the two are

closely related. In fact as has been shown hy Hansen the only

point of difference between these lies in a single but well-marked

character; in Trithyreus the second tergite is divided or nearly

divided into two lateral parts by a median suture or line and

in Schizomus the second tergite is one piece. The number of

joints in the flagellum is not a good generic character. In most

species of Trithyreus it is three-jointed but in all the California

representatives of this group that I have examined it is clearly

four- jointed. Many members of the genus Schizomus are four-

jointed but mine from Cuba and some others described are three-

jointed.

Schizomus antilus Hilton, n. sp.

Cephalothorax: Head with a faint eye-spot on each side.

Cephalic sternum slightly longer than broad, second cephalic ter-

gite one piece.

Palps: Moderately heavy, less than one-half the length of the

body or 1.90 mm. long to 4.5 mm. body length. The front lower

angle of the trochanter forms a sharp angle. Its outer part bears

five large marginal hairs and two smaller ones. The claw is

slightly longer than the tarsus.

First Leg : Slender, about the length of the body or 4.513 mm.

The lengths of the joints are as follows: coxa, .53 mm.; trochanter,

.315 mm.; femur, 1.012 mm.; patella, 1.215 mm.; tibia, .765 mm.;

first metatarsus, .0225; second metatarsus, .31 mm.; first tarsus,

.045 mm.; second to fifth tarsals, .056 mm.; sixth tarsal, .13115

mm.

Fourth Legs: These are less than the length of the body or

3.825 mm. long. The femur is a little more than three times as

long as broad.

Three last abdominal segments not much telescoped.

Flagellum: About six times as long as broad, three -jointed,

the tip joint over twice the length of the basal joint which is

nearly twice as long as the second joint. Twelve hairs are borne

on the appendage.

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 2

Mcbnd'U)les: The fixed jaw bears a large outer pointed tooth,

a smaller inner double pointed tooth and three smaller teeth in

between.

Color: A light brown, the legs lighter.

Measurements: Length of body, 4.5 mm.; palps, 1.9025 mm.;

first leg, 4.51315 mm.; last leg, 3.825 mm.

Locality: Corail Nuevo, Cuba, at about 1500 ft. altitude in

a royal palm thicket.

Type: A female, in the Pomona College collection. This

was compared with several from the same locality and others

from near Havana, all seemed to be the same species.

This species seems nearest S. flavescens Hansen according to

keys and description, but differs in several points. The char-

acter of the teeth on the fixed finger of the mandible is distinc-

tive as also the hairs on the free margin of the coxa of the palps.

Two Interesting New Records

Eudistenia costipennis Fall. Two examples of this rare

species were taken from pupal chambers in the hard dead wood

of Quercus chrysolepis at Chiquito Basin, Madera County, Calif.,

elevation 4500 ft., on April 4, 1932, by Mr. R. L. Furniss.

Although Dr. Fall’s original specimens were beaten from oak,

and later specimens have been captured on a dead yellow pine

stump in Yosemite Valley, Calif., this is the first definite host

record regarding this species.

Aneflomorpha longipennis Casey. Data concerning the flight

period of this species has been recently obtained by Mr. A. E.

Michelbacher of the University of California. During the sum-

mer of 1931 Mr. Michelbacher was running a series of light

traps at Clarksburg, Yolo County, Calif., in connection with an

experimental problem, and observed this insect coming in num-

bers. The first specimens appeared on July 8, and the last on

September 25. The species was most abundant in the latter part

of July and seemed to prefer warm evenings for flight. In view

of the rarity of this species in collections it is interesting to note

that, during 1931 at least, its flight period lasted more than two

months. — E. Gorton Linsley.

LINSLEY— A NEW NEOCLYTUS

A NEW SPECIES OF NEOCLYTUS FROM WHITE FIR

(Coleoptera, Cerambycidge)

BY E. GORTON LINSLEY

Oakland, California

Neoclytus nubilus Linsley, new species

Elongate, dark brown, rather sparsely sprinkled with white

pubescence. Head moderately finely punctured, somewhat granu-

late; antennEe slightly more than half as long as body ( 5 ) , about

half as long as body ( 2 ) , not appreciably thickened apically.

Prothorax without fasciee, sparsely and irregularly clothed with

white hairs; about as long as broad, base slightly wider than apex;

transverse carinae numerous, confined mainly to median area, api-

cal Carina nearly as long as two- thirds the width of the head;

puncturation dense, moderately coarse. Scutellum black, naked.

Elytra two and one-half times as long as broad; each elytron with

three rather ill-defined fasciae as follows : a broken fascia at basal

third consisting of a short white line placed obliquely forward to

the suture and a small round lateral spot, a V-shaped fascia a

little anterior to apical third, and an irregular transverse line at

apical sixth, the apices and area anterior to mid-ifascia clouded

with white pubescence; apices obliquely truncate. Body beneath

and legs, irregularly clothed with white hairs. Length 15 mm.,

breadth 4 mm.

Type, female (No. 3699, Mus. Calif. Acad. Sci) and allotype,

male (No. 3700, Mus. Calif . Acad. Sci. ) , collected at Bass Lake,

Calif, on July 15, 1932, by Mr. R. L. Furniss, who very kindly

submitted the specimens to me for study. Paratypes from the

same series in the collection of Mr. Furniss, Mr. Geo. Hopping,

and the writer. I am also indebted to Mr. J. M. Miller of the

United States Department of Agriculture for the privilege of

examining five additional specimens (also designated paratypes)

from Long Barn, Calif. (Hopk.U.S. I935Ig), G. R. Struble col-

lector, in the collection of the United States Dept, of Agriculture

at Berkeley. All specimens were reared from Abies concolor.

The female of this species was associated by Dr. Fall with

the males of Neoclytus modestus in his original" description of

the latter, and an example in the collection of Mr. Ralph Hopping

• from Kaweah, Calif., hearing a paratype label of modestus Fall,

is clearly referable to N. nubilus. The resemblance between the

males of N. modestus and the two sexes of N, nubilus is rather

noticeable, but in the former species the sexes are very disimi-

lar, and the scutellum densely clothed with white or yellowish

pubescence. N. modestus is usually found in the lower alti-

tudes on Quercus agri folia and related species of oak, whereas

N. nuhilus is a high altitude form found on Abies concolor.

The species is much more closely related to Neoclytus murica-

tulus, and in Mr. Geo. Hopping’s recent revision," runs near

that species. It differs from the latter in size, coloration, type

ofi pubescence and prothoracic sculpturing. That portion of Mr.

Hopping’s Key to Neoclytus (p.547) which treats related spe-

cies, may be modified as follows for the insertion of N. nuhilus:

CC. Antennae not appreciably thickened distally.

D. Scutellum naked.

E. Elytral fasciae obscured by clouded white pubes-

cence; basal fasciae incomplete. 10-16 mm. Cali-

fornia nuhilus n. sp.

EE. Elytral fasciae clearly defined, distinct; basal fas-

ciae semi-circular, extending across the base of

the elytra.

F. Each elytron with a fascia extending for-

ward from the outer end of the mid-fascia.

LINSLEY— A NEW CLERID

A NEW CALIFORNIA CLERID BEETLE

(Coleoptera)

BY E. GORTON LINSLEY

Oakland, Calif orrda

The following species has stood under a manuscript name

for some time, hut has been left undescribed during certain ob-

servations on its life history. Although these studies are not

yet completed, it seems best that the species be made known at

this time. The description below will, I think, sufficiently diag-

nose the species, and is offered in advance of a more compre-

hensive paper which will appear at a later date.

Aulicus terrestris Linsley, new species

Head black, coarsely, densely punctured; palpi black; antennee

piceous, basal segments reddish. Prothorax black, constricted at

base and before apex; surface coarsely, sparsely punctured, sub-

apical constriction and median area smooth. Elytra bluish-black,

humerus and a subapical spot red, the two connected along the

lateral margin by a narrow red band. Legs black, claws simple

in both sexes. Body black; abdomen black, margin and apical seg-

ments red; fifth ventral of female truncate, of male, emarginate

at apex. Length 10 mm., breadth 4.5 mm.

Holotype, male (No. 3701, Calif. Acad. Sci.) and allotype,

female (No. 3702, Calif. Acad. Sci.) collected by the writer on

the east slopes of Mt. Diablo, Calif., May 10, 1931. Paratypes

(collected May and June I93I-I932) in the collections of Dr.

E. C. Van Dyke, Mr. E. C. Zimmerman, Mr. A. T. McClay, Mr.

E. R. Leach, and the writer. Paratypes also deposited in the

collections of the U. S. Nat. Museum, Mr. A. B. Wolcott, and

Mr. J. N. Knull.

This species resembles A. dentipes Schffr, but differs in hav-

ing the blue sutural vitta of the elytra wider than the red humeral

space and in having all tarsal claws in both sexes uncleft. From

A. nero (described from Mexico) it may be distinguished by the

presence of a blue median fascia (entirely lacking in nero) and

by the black ventral segments. A. terrestris appears to be a

very constant species. In a long series studied there is little

variation in size or color.

A NEW LOPIDEA FROM CALIFORNIA

BY E. P. VAN DUZEE

Lop idea usingeri Van Duzee, n. sp.

Much like marginatm Uhler with the genital characters nearly

of nigridea Uhler and fallax Knight; posterior disk of pronotum,

scutellum and elytra dark sanguineous, the latter with a pale

costa; length 6 mm.

Head as in marginata, but with the post-ocular callous less

conspicuous and the front fuller; antennee perceptably stouter;

pronotal humeri broadly rounded; rostrum attaining intermediate

coxae. Dextral male clasper very similar to that of nigridea but

with its apex more oblique, the apical margin armed with a short

black tooth near the prominent inferior apical angle and the basal

dorsal hook more obtuse, straight and produced at a right angle;

dextral spine of pygofer as in marginata. In obscura this clasper

is narrower, its ventral apical angle more rounded, the supple-

mental dorsal tooth represented by a tubercle and the dorsal basal

hook curved as in nigridea. L. faMax Knight is very similar but

has the dextral clasper serrate at apex and wants the supple-

mental tooth before the apex.

Color pale yellowish, the posterior lobe of the pronotum,

scutellum and elytra dark sanguineous and the costal margin

narrowly whitish; base of vertex, a basal arcuate vitta either side

of the front, clypeus, antennse and rostrum black; feet fuscous,

femora paler at base ; tarsi black ; narrow sutural and commissural

margins black; membrane smoky; cheeks and disk of propleurae

tinged with red; ventral segments infuscated at base, becoming

reddish laterally; genital segment fuscous at base, dextral clasper

hed its spines tipped with black.

Described from two males and five females. This species,

like obscura exhibits considerable variation in the depth of color-

ing but generally the disk of the elytra, especially in the female,

is quite broadly blackish. It gives me pleasure to dedicate this

species to its discoverer, one of our enthusiastic young ento-

mologists, who is doing good work in the Hemiptera.

HUDSON BAY BUTTERFLIES AND A NEW

TRANSITION FORM (LEPID.).

BY A. V. HARPER

McCreary, Man., Canada

The year of 1932 gave me the much desired opportunity of

visiting that vast territory of northern Manitoba which stretches

between my home town of McCreary and the terminal of the

Hudson Bay Railroad at Fort Churchill on Hudson Bay, Leav-

ing June 1st the first stop for exploration was at The Pas some

400 miles northward. The scenery en route was mostly prairie

with some mixed woods, though the last 50 miles showed more

muskeg and swamp spruce. The Pas is a small frontier settle-

ment of about 3000 inhabitants and many trappers still make

this place their summer headquarters before proceeding north

for winter operations. In Lepidoptera, the butterfly Brenthis

freija was flying in considerable numbers and I also took Bren-

this dawsoni in the spruce swamps. Two collecting days were

spent at The Pas.

My next stop was at Wabowden, a small Indian village nes-

tled among numerous lakes and rocky situations. Collecting

was better here than at The Pas and I was fortunate to have a

few warm, clear days; however, it was a little early in the year

for everything to be out in quantity, A few Brenthis saga were

taken and Brenthis triclaris (near it) were just coming out.

Leaving this little railroad point and continuing northward,

the train crosses the Nelson River at Kettle Rapids, a very in-

viting looking spot, though I did not stop over. From here on

the trees get smaller and shorter, also farther apart, and the

majority of them seem killed by prairie fires, possibly started

by the railroad. Arriving at Herchmer about 5 o’clock in the

afternoon, I lost no time in swinging the net, as the weather

was good and of course the days are long. Most of the col-

lecting was done along the Owl River and the best spot seemed

on a gravel ridge east of the railroad, Frigga was common

THE PAH -PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 3

and I also took Eurymus palceno chippewa and what I think is

Eurymus gigantea. I worked this region over until June 30th

and then decided to move on to Fort Churchill, Between there

and Hudson Bay there are about 35 miles of the first moss

barrens and then the railway runs through the thick tamarac

swamps along the Churchill River. This tamarac is amazingly

thick and extends to within five miles of Churchill where the

real Arctic Barrens begin,

Churchill is the farthest north deep seaport on the Ameri-

can continent, being well situated at the mouth of the Churchill

River which makes a natural opening and protected harbor into

Hudson Bay, A feature of the town is the giant grain elevator

which can be seen for miles around. My real reason for com-

ing to Churchill was to locate and collect that rare Colias but-

terfly Eurymus nastes moinna Stkr, at its type locality. This is

the butterfly which the late Dr. Wm, Barnes of Decatur, 111,,

wished to obtain, but was evidently unable to. After tramping

around for several days I eventually found a colony of them

about 4 miles southeast of the elevator along the coast on a

few acres of level ground among the rocks. And was I happy!

Like most Colias these butterflies like warm, sunny days and I

was favored with quite a streak of good weather during my

three weeks’ stay at Churchill, Mosquitoes are bad, of course,

as is a species of small, black fly and the face and hands must

be protected at all times. Along with moinna, I took Plebius

aquilo. A few Eurymus hecla glacialis were also caught though

they are very swift fliers and not local in habits like moinna.

Erehia disa and rossi were in fair numbers and also several

Oeneis. I took a few specimens of Papilio machaon hudsoni-

anus during my stay; this is a new Papilio described by A. H,

Clark, the Echinodermist of Washington, D. C,, and evidently

approved by F. H. Benjamin. The best region for butterflies

around Churchill was along the rocks near the Bay, though I

also collected up the Churchill River a distance. The weather

gets fairly warm towards the middle of the day and as the

days are about 20 hours long, one has plenty of time compara-

tively. It is estimated that there are over 100 varieties of wild

flowers in the immediate district and an equal number of mi-

gratory birds which nest there,

I left Churchill on July 22nd for the return journey home

July, 1933]

HARPER— HUDSON BAY BUTTERFLIES

and considered that I had done well in Lepidoptera, having

taken about 15 species which included several Sphingidoe and

Apantesis. The return trip took three days, not long consider-

ing the distance. The item of rail fare is the principal cost

on an expedition into the Bay region. The Canadian National

gladl)^ furnishes estimates to anyone interested, so I am told.

I take this opportunity of describing a new tr. f. as follows:

Brenthis freija gunderi Harper, new tr. f.

Upper side: Primaries heavily black suffused through dis-

cal area with cell spots much enlarged and spots through base

flattened to fill interspaces. Secondaries having the marginal row

of black spots fused outwardly and joining the lunate row. Dis-

cal and basal areas black as in typicals. Under side: Black macu-

lation of upper sides repeated as on under sides of primaries; sec-

ondaries showing duplicate tendencies of suffusion as indicated on

upper surfaces. This transition form representing the type for

melanifusism is only a partial development, but is recorded as an

example of change of pattern.. The name freijw Thun, properly

represents a European habitat; perhaps the name tarquinuis Curt,

really represents the Canadian group, though those Labrador ex-

amples are said to vary as well.

Holotype male, McCreary, Manitoba, Canada. May 22nd,

1932. Expanse of type 37mm. Collected by myself and type

deposited in the Calif. Academy of Sciences at San Francisco,

Calif, as an “indefinite loan” for safe keeping. It is named

after Mr. J. D. Gunder of Pasadena, Calif.

A New Record of Arizona Hemiptera

emy of Sciences. A specimen has recently been received through

NOTES ON THE SPECIES OF THE OCHROPTENA—

CIRCUMLUCENS GROUP OF PAPAIPEMA

(Lepid., Phalgenidae)

BY FOSTER H. BENJAMIN

Bureau of Entomology , U. S. Department of Agriculture,

Washington, D. C.

Submission of specimens for identification has caused the

writer to investigate the present group. Two previously de-

scribed species and one previously described subspecies are dis-

cussed; one new species and one new subspecies are described.

Thanks are due to Mr. Henry Bird who has reviewed the data

on which this paper is based and examined the types of the

new species and subspecies.

pp. 304-306.

The truncate nature of the distal portion of the harpe, to-

gether with the clasper being sharply bent at nearly a ninety-

degree angle, are characters which differentiate the hop-feeding

species, ochropiena, from its allies.

One specimen from Cartwright, Manitoba, is almost iden-

tical with typical (Colorado) ochroptena., while five others from

the same locality show some rufous shadings and, in this re-

spect, are intermediate to the eastern race, humuli.

This subspecies bears the same relationship to the darker

typical circumlucens that ochroptena ochroptena bears to the

darker ochroptena humuli and in consequence usually has been

misidentified as ochroptena.

Size and markings essentially the same as in specimens of

circumlucens from eastern localities, but the ground color of the

fore wing pale yellow, scarcely powdered with rufous, the mark-

ings proportionately pale and un contrasting. Hind wing straw

color, almost devoid of the rufous tints and shadings conspicuous

on specimens of typical circumlucens. Male genitalia essentially

the same as those of the eastern (typical) subspecies. Expanse:

Notes: Additional specimens include a male labeled Den-

ver, Colo., 16-23 Sept, and which has been discussed by Barnes

field, Utah, 6 Sept. 1929 (David E. Fox).

Color and appearance similar to vaha, but the fore wing with

the transverse anterior space between costa and submedian fold

and all of the subterminal space disconcolorously filled with dull

purplish fuscous, which also strongly marks the veins and forms

a heavy connecting bar between the orbicular and the reniform,

the wing in consequence appearing contrastingly marked, a fea-

ture further emphasized by the lack of the usual rufous powder-

ings; reniform somewhat narrower than normal, the surrounding

spots slightly reduced in size; median shade unusually erect and

less nearly parallel with the transverse posterior line than nor-

mal in the group. Hind wing pale yellow slightly tinged with

purple-rufous shadings. Male genitalia similar to those of cir-

cumlucens, but the uncus more of a diamond shape, and the penis

possessing a longer spatulate spine. Expanse: 40 mm; $,

37 mm.

Holotype S, Allotype 2, White Mts., Ariz. Cat. No. 44736

U.S.N.M.

Notes: The allotype has been figured by Barnes and Mc-

Dunnough as ochroptena. See notes under P. ochroptena vaha.

Another Rare Species Located

It was during the summer of 1932 that my friend, Mr. Doud-

oroff brought a splendid looking CEneis back from a collecting

trip in Mendocino County. Upon investigation I found that my

suspicions were well founded and therefore a great deal of time

was spent this season trying to obtain a series. By the end of

June we succeeded in catching a number of specimens in the

ravines north of Manchester, California. However, they were

all males while the specimen obtained in 1932 was a female.

These CEneis I consider one of the most beautiful of that group,

and probably one of the rarest. The species is none other than

CEneis iduna and in many collections is probably one of the

rarest butterflies.

It would be an interesting thing for Lepidopterists in the

future to attempt to locate a spot; where iduna flies more abund-

antly, as the typical form seems to be very local. We found

none at any great distance north of Point Arena and all attempts

to find them more than thirty miles south of Manchester were

also futile. They are very difficult to locate and not more than

one specimen was ever seen at one time. Future reports on

this species would be interesting. — R F. Sternitsky.

NOTES ON SOME HISPINI AND CASSIDINI AND

DESCRIPTIONS OF NEW SPECIES

(Coleoptera, Chrysomelidse)

BY CHAS. SCHAEFFER

Brooklyn Museum, Brooklyn, New York

Anisostena arizonica Schaeffer, new sp.

Form and size of nunnenmaeheri; color of upper surface

reddish castaneous with more or less distinct dark metallic tint;

underside dark metallic, legs and antennae reddish, three inter-

vals on each elytron distinctly costate. Head dull, alutaceous,

with a few scattered punctures on each side of the deep frontal

impression. Prothorax about as long as wide at base, sides

scarcely arcuate and feebly narrowing to apical angles which are

rather indistinct, basal angles distinct, disk closely and coarsely

punctate. Elytra wider than prothorax at base, humeri obliquely

rounded, three intervals on each side distinctly costate, the serial

punctures between these coarse and close; lateral and apical

margins entire, not serrate. Ventral segments subopaque, each

with a transverse row of very fine punctures near apical margin.

Length: 3 mm.

Arizona.’

The darker coloration of upper and under side, each elytron

distinctly tricostate, and the more densely punctate pronotum

separates this species from nunnenmaeheri, the only one of our

species with which it could be confused. A. nigrita is a larger

species with relatively stouter antennal joints and larger ely-

tral punctures.

Anisostena texana Schaeffer, new sp.

Near a/riadne in color and form, but the red color of pro-

thorax is darker, the elytra are slightly narrower and a little

longer, the first interval is feebly convex but not costate except

apically, the second subcostate and the third narrow and acute;

the space separating the serial punctures from each other, is not

raised as in ariadne; the prothorax is longer and the third an-

tennal joint is more elongate in texana. Length: 4.25 mm.

Brownsville, Texas, (0. Dietz).

This species is rather close to the Arizona specimens which

the late Julius Weise doubtfully determined as funesta Baly, of

^ Types of new species in collection of the author.

104

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 3

which one specimen has a very obscure reddish prothorax with-

out metallic tint, except being darker along anterior margin as

usual in the species with reddish prothorax. However, the pro-

thorax in texana appears to be a little longer, the sides from

an anterior view feebly diverging basally — in these funesta

slightly converging — otherwise the sculpture of prothorax and

elytra is nearly alike in both.

Anisostena kansana Schaeffer, new sp.

Head, underside and legs black with faint metallic tint; pro-

thorax red; elytra bright bluish green. Head opaque, with the

usual frontal impression. Prothorax at base as wide as long,

sides moderately arcuate, slightly narrowing from about middle

to apical angles which are feebly distinct; disk irregularly punc-

tuate, punctures almost absent at middle, a little more numerous

at sides and base. Elytra a little wider than the prothorax at

base, humeri obliquely rounded, lateral margins not serrate, api-

cal margins feebly and distantly serrate; first and second elytral

intervals, between the geminate rows of punctures, rather flat,

the second convex apically, the third narrow, carina-like. Metas-

ternum with a few punctures, ventral segments impunctate, ex-

cept the last which is distinctly punctate. Length: 5 mm.

Medora, Kansas (W. Knaus).

The wider pronotum, with slightly more arcuate sides and

sparser irregular punctuation, also the bright blue color of ely-

tra with the first interval flat, and the second nearly so, distin-

guish this species from those that are bicolored above.

Anisostena bicolor Smith

This species, described and recorded so far only from New

Mexico, occurs also in Arizona.

Anoplitis rosea Weber

This species does not seem to be well recognized as I have

seen it usually mixed in collections with incequalis. The color

and markings are the same and are as variable as in the latter ;

the antennae in rosea, even in the darker specimens, are appar-

ently always pale, in incequalis usually black in the dark as well

as pale specimens, though occasionally a specimen is found

with pale antennae. The elytra are very distinctly and rather

suddenly dilated near apex in rosea as in Baliosus ruber and

the apices are more broadly and feebly rounded than in ince-

qualis; the third costa is more distinctly arcuately elevated near

apex and the second costa unites apically with the third in a

SCHAEFFER— CHRYSOMELID^

105

rather broad arc, in inoequalis usually when connected, in a

more or less acute point.

The specimens with black or piceous elytra and the apex

more or less pale are var. philemon.

It is not a rare species but apparently as common as ince-

qualis, at least in certain localities.

Anoplitis ancoroides Schaeffer, new sp.

Flavous, head posteriorly, antennae, lateral margins of pro-

notum narrowly and a short, oblique, more or less distinct line

on each side of middle black; elytral suture bluish black from

the scutellum to about middle, dilated at its apex on each side

into a short branch, reaching to and involving the first costa,

another short oblique branch is situated on each side a little be-

low the scutellum, slightly above the short apical branch on the

second costa is a small obscure spot which is more or less con-

nected with the apical branch producing a somewhat anchor-like

design, laterally near apex are three small spots and below these

from the first costa to the suture an oblique line black. Pro-

thorax nearly parallel -sided to about apical third, thence obliquely

narrowing to apex, apical angles produced, sub-acute; surface

rather coarsely and densely punctate. Elytra parallel-sided, not

wider apically, lateral and apical margins very indistinctly and

distantly serrulate; surface with three costiform elevations and

four geminate rows of coarse punctures. Body below black or

piceous, last ventral segment and legs pale. Length: 3 mm.

Merchantville, New Jersey.

This species looks at first sight like a more feebly marked

specimen of the variable incequalis, however, the elytra are not

wider apically and the elytral markings are different, that is,

the laterally pale specimens of incequalis never have the suture

marked as in ancoroides but in great part pale.

Brachycoryna lateralis Schaeffer, new sp.

Form and coloration of longula but larger, pronotum shining,

with punctures less close and usually well separated. Head black

with faint greenish tint, on each side of the moderately impressed

median line an irregular row of punctures which are more or

less longitudinally confluent. Pronotum luteous, wider than long,

sides nearly straight and feebly narrowing near apex, surface

with moderately large punctures, sparsely placed at middle, more

closely at sides and base. Scutellum black. Elytra rather elon-

gate-oval; humeri obliquely rounded; lateral and apical margins

not dentate; surface with three costiform intervals and four gemi-

nate rows of moderately large punctures; color flavous with two

106

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 3

dark spots on each elytron, one at about apical third near the ele-

vated suture and one, slightly above the latter, on the second ele-

vated interval. Body beneath dark metallic green; legs pale, tarsi

black. Length: 2.5 mm.

Fort Collins, Colorado.

This species looks like a larger specimen of longula but the

pronotum is less densely punctuate and more shining, the ely-

tral punctures are less coarse and the interval between the sec-

ond and third costae is nearly equal to that between the third

and lateral margin and has two distinct rows of punctures,

while in longula the interval between the second and third

costae is much wider than between the third costa and lateral

margin, and has three or four very confused irregular rows of

punctures as in the other species of the genus. The tarsi are

formed similar to those of Stenopodius flavvdus, that is, the

third joint is short not dilated nor prolonged on each side and

subequal in size to each of the preceding joints.

The tarsal structure of this species somewhat bridges over

the difference between Brachycoryna and Stenopodius.

Stenopodius flavidus texanus Schaeffer, n. var.

Same coloration, form, sculpture of prothorax and elytra as

in typical flavidus, but slightly smaller, the median prothoracic

lobe at anterior margin narrower, the impression between the

latter and lateral angles deeper and darker colored, causing the

anterior angles and the narrow median lobe to appear more promi-

nent. The ante-scutellar basal lobe' is rather indistinct. Length:

3.5 mm.

Brownsville, Texas.

A small number of specimens collected by the late Ottomar

Dietz and myself. They were taken by sweeping in and around

old and neglected cotton fields.

Microrhopala rubrolineata Mann

The majority of specimens taken in the Huachuca Moun-

tains, Arizona, have the lateral red vitta on each elytron very

wide below the humeral callus as in the variety vulnerata, in

only a few specimens is this vitta narrow, occupying not more

than the wider fourth interval as in the California specimens.

Microrhopala rubrolineata vulnerata Horn

This variety occurs also in New Mexico (Ft. Wingate, Aug.)

July, 1933]

SCHAEFFER— CHRYSOMELID-^

107

The lateral yellowish elytral vitta is reduced in the single speci-

men from the latter locality to a wide, elongate, humeral spot

not quite extending to the middle of the lateral margin.

Pentispa suturalis vittula Weise

This variety, listed in the Leng catalogue, was described

from Mexico but apparently does not occur in the United States.

It differs from the typical form in the possession of a blue dis-

cal vitta on each elytron which is very narrow basally, but be-

comes very wide apically.

Mr. Julian Weise^ has placed my Microrhopala arizonica as

a synonym of Pentispa suturalis, possibly correctly so. How-

ever, my Arizona specimens do not entirely agree with Baly’s

description of suturalis. The underside and the scutellum of

the latter species are said to be black, both distinctly blue in

arizonica, in the latter there is a dark blue median vitta on the

pronotum, variable in length but always present, and lateral

margins narrowly dark, the apical and also lateral margins of

elytra in about apical third are narrowly blue, all of which is

not mentioned in the description of suturalis. The apical and lat-

eral margins in typical suturalis are apparently reddish like the

rest of the surface as Weise says of the variety “auch der Seiten-

rand (of elytra) ist an der hinteren Aussenecke dunkel gesaumt”,

so this is apparently not so in typical suturalis.

Cassida flaveola Thunb.

A specimen of this European species was collected at Mil-

ford, Pa., July 2, by Mr. A. Nicolay, and Mr. Bowdoin has

taken specimens near Baltimore, Md., in May, which extends

its distribution further south than recorded so far.

Cassida nebulosa L.

The occurrence of this European species in North America

is apparently based on a single specimen received by the late

Dr. Horn from A. Bolter and said to have been collected near

the Santa Anna River in California. If the specimen really

came from California the species does not seem to have gained

a foothold there as I am not aware that it has ever been found

again. The doubtful New York locality in the Leng catalogue

is a specimen of flaveola which I had taken at Suffern, New

York, and recorded quite some years ago in one of the meet-

ings of the N. Y. Entomological Society as being possibly the

European C. nebulosa.

Chelymorpha phytophagica luteata Schaeffer, n. var.

Differs from typical phytophagica- in being flavous above with

the usual black spots on prothorax and elytra; below flavous ex-

cept a median fascia on each of the first four ventral segments,

also femora at apex and tibise laterally black. Punctuation and

pubescence of upper surface as in typical phytophagica. Length:

9 mm.

Tucson, Arizona, August.

This is possibly only an individual color variation, regard-

ing the largely pale underside and legs, the yellowish color

above may be due to sexual immaturity. However, it resem-

bles cassidea lewisi so closely that it is apt to be mistaken for

that form. It differs from the latter in having the upper sur-

face pubescent and the elytral epipleurae very distinct in its

entire length, the epipleurae in lewisi apically is entirely dif-

ferent and formed as in cassidea and its two varieties genicu-

lata and 17 -punctata.

Psalidonota texana Schaeffer, n. sp.

Eotundate, flavo-testaceous ; elytral punctures more or less cas-

taneous, the suture' more or less and the post-scutellar sutural

gibbosity, reddish; body beneath more or less black, except lat-

erally and ventral segments and legs, which are pale; antennse

pale, last joint black. Prothorax transverse, the base rather

feebly sinuate on each side, median lobe broad and truncate; sides

straight, oblique; anterior margin broadly arcuate, anteriorly and

laterally widely hyaline and reticulate; surface smooth and im-

punctate. Elytra wider than the prothorax, deeply sinuate on

each side of the base, apices conjointly rounded; humeral callus

distinct; disc convex, with a rather strong, transverse, post-scu-

tellar gibbosity, and rows of coarse punctures which are irregu-

larly interrupted by smooth elevated spaces, two of these smooth

lines extending obliquely from the base of the gibbosity to the

lateral hyaline margin or nearly so, producing a more or less

distinct wishbone-like pattern; the margins rather widely ex-

panded anteriorly, becoming much narrower apically, subhyaline

and reticulate. Length: 8 mm.

Brownsville, Texas.

This is the species identified, I believe, by the late Dr. Horn

as leprosa and is so listed in our catalogue. However, leprosa

is a much larger species, 11 mm. in length, has the under side

entirely pale and on each elytron, below middle, one oblique

smooth space which becomes much wider externally. It agrees

much better with the description of marmorata but that spe-

cies is 9-9.5 mm. in length and has the elytra feebly gibbous,

while in texana the elytra are rather strongly gibbous and even

more suddenly so anteriorly than in leprosa, that is, if the out-

line drawings on plate 10, figs, la and 2a of Vol. VI, pt. 2 of

the Biologia are correct.

Why Perpetuate Errors?

A number of errors have crept into the nomenclature of our

insects that seem to call for a protest. I will mention three

here that are already causing confusion in the minds of some

of our younger entomologists and the longer they are in use

the more difficult it will be to correct them. In 1926 Barnes

and Benjamin published in the Bulletin of the Southern Cali-

fornia Academy of Sciences a Check List of the Diurnal Lepi-

doptera of America north of Mexico, in which use was made

of Hubner’s Tentamen, a leaflet not accepted by the Interna-

tional Committee on Zoological Nomenclature. Unfortunately

a number of the invalid names there adopted from the Tenta-

men are being used by some of our California lepidopterists.

Another erroneous name for which we are indebted to Barnes

and Benjamin is the use of Phalaenidae in place of Noctuidae.

Linnaeus used Phalaena as a group name dividing it into a num-

ber of what would now be considered as genera, and for none

of which did he use his name Phalaena. Lamarck in 1801 was

the first to use the name Phalaena in the modern generic sense

and he used it for a geometrid moth which thus becomes its

type. As a family name it will thus displace the name Geomet-

ridae, and in this sense it was used by Packard and other early

entomologists. An error for which we are not indebted to

Barnes and Benjamin is the use of Hemiptera in place of

Heteroptera by those who split that order. Personally I con-

sider the dividing of this order as illogical as would be the

dividing of the order Lepidoptera into Rhopalocera and Hetero-

cera, confining the term Lepidoptera to the diurnals. There

is absolutely no justification for the division of either of these

orders. Those in doubt on these points should take the time

and trouble to look up the history of these names before adopt-

ing the change. — E. P. Van Duzee.

[VOL. IX, NO. 3

A NEW TRIBE OF CARABID^ (COLEOPTERA)

FROM WESTERN UNITED STATES

BY P. J. DARLINGTON JR.

Museum of Comparative Zoology, Cambridge, Mass.

The following is a very isolated new tribe of G. H. Horn’s

subfamily Carabinae of the beetle family Carabidae:

Gehringiini

Chief tribal characters: Mesosternal epimeron attaining mid-

dle coxa; front coxal cavities open behind; hind coxae separated;

front tibia broadly emarginate on inner side, variable spur dis-

tant from apex; sides of elytra broadly bent under body, with-

out special internal plica or marginal interruption; palpi stout,

last joint slender, almost subulate; antennae moniliform, inserted

under slight frontal costae; mandible with seta in scrobe; single

fixed seta over eye.

This tribe is founded upon the following genus:

Gehringia Darlington, gen. nov.

Size minute; general appearance like Bembidion; entire up-

per surface sparsely and inconspicuously pubescent. Epimeron

of mesosternum narrowly but definitely reaching coxa; front

coxal cavities open behind, prosternal process not prolonged be-

hind coxae; middle coxae separated by about one-half their own

width; hind coxae separated by one-fifth or one-sixth width of

body including elytra, posterior edge of metasternum reaching

second abdominal segment medially; first ventral visible at sides

but not between coxae. Front tibia simply rounded at apex, broad-

ly emarginate on inner side, variable spur distant from apex;

tarsal claws simple; male front tarsi not dilated, but with in-

conspicuous sexual vestiture. Head rather short, bi-impressed

between anterior edges of eyes, front not otherwise sulcate ; eyes

moderate, narrowly separated from mouth below, coarsely fa-

ceted, sparsely set with short pubescence; supraorbital fixed seta

single, opposite posterior margin of eye; antennae inserted under

slight frontal costae, basal joint only glabrous, first three joints

subequal, about twice as long as wide, outer joints perfectly monili-

form; clypeus subtruncate in front, with two setae each side near

margin; labrum moderate, subtruncate in front, with three setae

each side on front margin, the inner very short; mandibles short,

arcuate, acute, with seta in scrobe (detectable only in some speci-

mens) ; mentum deeply emarginate, toothed at middle, tooth ir-

regularly blunted at apex, with two inconspicuous setae at base;

ligula narrow, parallel, bisetose at apex; paraglossae wider than

July, 1933]

DARLINGTON— CARABID^

111

ligula, of same length; whole labium (ligula + paraglossse) nearly

square, truncate at apex; labial palpi with penultimate joint

stout, bisetose in front, apical joint slender, slightly shorter;

maxillae with inner lobe curved and acute at apex, spinulose on

inner margin, outer lobe of equal length, basal joint stout, outer

joint slender ; maxillary palpi very short and stout, penultimate

joint slightly serrate on inner side, apical slender, shorter, almost

subulate. Prothorax cordate; pronotum with seta in posterior

angle and in side margin one'-third from apex on each side. Scu-

tellum distinct. Elytra not margined at base; scutellar stria ab-

sent, sutural stria deep, striation otherwise obsolete; no special

discal sete; outer edge of elytron broadly bent under body, reach-

ing outer end of hind coxa, the bend being inside the ordinary

explanate margin which is therefore carried under the body ex-

cept near humerus; no special internal plica or marginal inter-

ruption. Wings long but with anal area greatly reduced; vena-

tion of Carabid type but reduced; most of margin fringed with

hairs.

The genotype is:

Gehringia olympica Darlington, sp. nov.

Figures 1-6

Form as shown in Fig. 1. Piceous black, antennae, legs, and

parts of under surface rufescent. Front impunctate, shining, but

with a few short, inconspicuous hairs in addition to the supra-

orbital fixed setae. Pronotum finely margined at sides, not mar-

gined at base; edge of base, and side margins posteriorly, more

or less crenate; disk with rugose transverse impression across

base between small depressions in posterior angles, median longi-

tudinal impressed line very fine, no transverse impression anteri-

orly; surface of disk shining, impunctate, but finely and sparsely

pubescent. Elytra not margined at base; explanate lateral mar-

gin very narrow, bent under body as described above; sutural stria

entire, deep, impunctate; second and third striae sometimes faint-

ly, irregulariy impressed for part of their length, sometimes com-

pletely obliterated, as are outer striae; intervals 1 to 3 each with

a single row of punctures bearing inconspicuous hairs; rows of

similar punctures corresponding to outer intervals progressively

less regular, the punctures very irregularly placed externally and

apically; surface between puctures smooth, shining; epipleurae

impunctate, shining. Anterior tarsi of male not perceptibly di-

lated, first three joints with scanty sexual pubescence below.

Length to apex of elytra ±1.6 -1.7 mm.

Holotype, female (on point), allotype, male (dissected, on

slide), and 6 paratypes (^ $ $ $ on points, original condition;

in the river. Six paratypes ( 5 5 ,4 2 2 ) from Glacier Park, Mon-

tana, June 30 and July 8, taken by Miss Edith Mank and lent

to me by Mr. H. C. Fall. Type, allotype, three ( ^ 2 ) Olym-

pic Mts. paratypes (including all dissections), and one (2)

Glacier Park paratype in the Museum of Comparative Zoology,

type number 17,243. One Olympic Mts. paratype each in the

collections of the California Academy of Sciences, H. C. Fall,

and the writer. Five Glacier Park paratypes in the collection

of H. C. Fall.

The genus Gehringia does not fit very naturally anywhere

among previously described Carabidae. It unquestionably falls

in the subfamily Carabinae (in the broad sense of G. H. Horn

and of the Junk Catalogue)" on the structure of the mesosternum,

and also on the incomplete closure of the anterior coxal cavi-

ties, a condition which is apparently unknown among Harpa-

linae. In Horn’s table of tribes (1881, 104) it falls between the

Cychrini and the following tribes, fitting neither portion of the

couplet. In Sloane’s classification (1923,242) it runs to the

Carabidae Apertae and falls between the Nebriini and Notiophi-

lini (couplet 25), fitting neither. The peculiar underlapping of

the edges of the elytra in Gehringia is, so far as I know, unique

among Carabidae. Even aside from this, however, the genus is

very strongly characterized. The separation of the posterior

coxae is not common, and the short, stout palpi, with the last

joint contrastingly slender are unique at least among Carabinae.

If the ventral structure and other inconspicuous characters were

overlooked, this insect might be considered a relative of the

Bembidiini (subfamily Harpalinae), for the general form and

the almost subulate palpi are very Bembidion-like, but I can

find nothing described in that tribe which at all fits Gehringia.

At one time during my study of the insect I even doubted

whether it belonged to the Carabidae, but the division of the

first ventral segment, the sutures of the posterior part of the

metasternum, and the general character of the wing venation.

1 Although the Carabinae of Horn is not a natural or phylogenetic sub-

family, its recognition is exceedingly convenient, and for that reason seems to

me to be desirable.

July, 1933]

DARLINGTON— CARABID^

113

as well as the general appearance, leave no doubt that it is a

true Carabid. Since it does not seem to be very closely related

to any previously described form, I am placing the tribe Geh-

ringiini provisionally almost at the front of the Carabinae, after

Trachypachus and before the Cychrini in Leng’s “Catalogue of

Coleoptera of America North of Mexico”.

The bending under of the sides of the elytra is presumably

an adaptation for supporting the abdomen; if so, it serves the

same function as the internal elytral plica of some other Cara-

bidae. I think there can be no question that the bending of the

elytra is a natural character, not due to warping after death,

for it is constant in the fourteen specimens I have examined,

and there is no distortion of other parts of the body in most of

the specimens. None of them is immature. The reduction of

the venation of the wings is probably directly correlated with

the small size of the insect, and is probably not in itself of

much significance (C/. Jeannel 1926, 329).

The name Gehringia has been adopted in honor of the late

Dr. John George Gehring of Bethel, Maine, who was one of

my earliest entomological correspondents and most stimulating

friends, and for whom I was collecting “on shares” when I se-

cured the types of the genus.

Our Travelers Return

Dr. E. C. Van Dyke recently returned from a fifteen months’

trip through Europe and northern Africa He attended the fifth

International Entomological Congress at Paris and the centen-

ary meetings of the Entomological Society of London but spent

much of the time studying the collection of insects at the British

Museum and those at Paris, Berlin, Vienna and other places.

About two months were spent traveling and collecting in Egypt

and Algeria. The results of his studies and his contacts with

European entomologists will add greatly to the value of the

Academy collection of insects,

Mr. Howard Hinton and Mr. Robert Usinger spent about

two months collecting in Temascaltepec, Mexico, bringing back

many interesting insects some of which will find their way into

the collection of the California Academy of Sciences. Mr. E.

Gorton Linsley took a trip east this summer visiting a number

of the larger insect collections there, studying types and com-

paring some of his uncertain species of longhorn beetles.

In early August Mr. Templeton Crocker returned from a

cruise among the Solomon Islands in his yacht The Zaca and

brought back for the Academy a considerable collection of in-

sects, which is especially welcome as we had little from those

islands except a collection of moths made there in 1921 by Mr,

J, A. Kusche. Mr. Crocker’s material was largely taken by his

secretary Mr. Maurice Willows, whose work in the Galapagos

Islands last year added so much to our knowledge of the insect

life of those interesting islands. — E. P. Van Duzee,

115

TWO NEW SPECIES OE SCARAB^ID^ (COLEOPTERA)

BY EDWIN C. VAN DYKE

University of California, Berkeley, Calif o'i'nia

Aphodius linsleyi Van Dyke, n. sp.

Of moderate size, robust, nigropiceous, undersurface some-

what rufous, moderately shining and not pubescent above. Head

without tubercles, occiput with a few coarse, umbilicate punc-

tures and numerous fine punctures; clypeus rather closely, finely

punctured and obscurely alutaceous; sides oblique, hardly arcu-

ate, gense prominent, anterior margin shallowly emarginate at

middle and rounded each side of depression. Prothorax about a

fifth broader than long, widest in front of middle, much narrowed

behind; sides almost straight posteriorly, arcuate in front, hind

angles evenly rounded; base arcuate, basal margin deep, com-

plete and continuous with lateral margin, deeply, closely punc-

tured; disk convex, coarsely irregularly, rather numerously um-

bilicately punctured and with very minute punctures scattered

over the intervening smoother areas, a faint median canalicula-

tion near base. Elytra elliptical, one fourth longer than broad,

humeri rounded with a small tooth; disk convex, deeply striate,

strise moderately coarsely and closely punctured, intervals cari-

nate, the first, third and fifth more prominent and very minutely

punctured. Wings apparently absent. Beneath more or less

coarsely, closely punctured in front, the abdomen shallowly punc-

tured at sides. Posterior femora sparsely punctured; hind mar-

gin of posterior tibiee fimbriate with short equal spinules; first

segment of hind tarsi about equal to following three segments

united. Length 5 mm., breadth 3 mm.

Holotype (No. 3739, Mus. Calif. Acad. Sci.), a unique, col-

lected by Mr. Gorton Linsley at the base of Mt. St. Helena,

Napa Co., Calif., March 22, 1930, and very kindly presented

to me. It was taken from cow manure.

This most interesting species belongs in the cadaverinus

group of Aphodius, a group which is quite restricted to and

characteristic of the Pacific Coast of North America. Its very

distinctive carinate elvtra will readily separate it from all of

its fellows. In the table' given by me, it should be placed be-

tween cadaverinus (Mann.) and sparsus Lee.

Poly phy 11a hirsuta Van Dyke, n. sp.

Medium sized and rather stocky, rufous with basal area of

head and discal part of pronotum piceous; upper surface clothed

with fulvous pile, long rather dense and sub-erect on the head,

pronotum and scutellum, short and depressed in the clypeal sulcus

and on the elytra; pile of elytra rather sparse though with a

tendency to be denser where the usual vittse are found, thus out-

lining vague and more or less interrupted vittse, the same con-

dition likewise existing with regard to the longer pronotal vesti-

ture. Head very coarsely, closely and deeply punctured; clypeus

deeply, transversely sulcate in front, its sides straight and paral-

lel, frontal margin almost straight, and outer angles rounded;

antennal club moderately large, about a third longer than basal

part of antennse. Prothorax with anterior margin rather evenly

and deeply emarginate, the base broadly, shallowly lobed at mid-

dle and with margins irregularly subserrate, and the disk coarse-

ly, deeply and rather regularly punctured, with median longitu-

dinal groove narrow and shallow. Scutellum irregularly, rather

coarsely punctured over entire area and entirely clothed with pile.

Elytra irregularly punctured and rugose over entire area. Pygi-

dium finely punctured and moderately, densely clothed with hair.

Beneath densely clothed with long fulvous hair in front, the abdo-

men less densely clothed with shorter, more appressed hair at

sides, quite smooth at middle. Anterior tibiee bidentate in male.

Length 20 mm., breadth 10 mm.

Holotype male (No. 3740, Mus. Calif. Acad. Sci.) and two

paratype males collected on Mt. Washington, near Nogales,

Ariz., alt. 6000 ft., July 20, 1919, by Mr. J. A. Kusche.

This reddish, hairy and non-scaled species with very indis-

tinct vittse should be easily recognized. It would perhaps come

just before diffracta Casey in Fall’s Key' but it is closely re-

lated to none of our previously described species.

Trachypachus Mots, {Trachypachys and Trachypachis Lac.)

The American species have recently been reviewed by Van

Dyke (Pan-Pac, Ent, I, 1925, p. 111-112). 1 am indebted to Dr.

Walther Horn of the Deutsches Entomologisches Institut for the

loan of a Transbaikalian example of T. zetterstedti Gyll, {trans-

versicollis and laticollis Motsch.) which 1 rely upon to establish

the cospecificity of this species with our inermis Mots, {holm-

bergi Mann,, oregonus and specularis Csy.). Van Dyke (l.c.) is

vague or misleading as regards the number of series of elytral

punctures. T. sleveni VanD. has eleven series of which the fifth,

seventh, and ninth terminate before the middle and the second

and sixth at about the apical fourth. T. zetterstedti Gyll. has from

three to nine rows, the majority of specimens in my series having

either four or seven. In counting these rows of punctures I dis-

regard the three series of widely spaced “dorsal” punctures,

T. gihhsii Lee. has about twelve rows,

CaRABUS (s. Str.) GRANULATUS L.

Since 1924 we have been taking occasional but repeated speci-

mens of this Palaearctic species in Seattle, Washington to the

east and northeast of the University campus. It has been re-

corded previously from North America only from New Bruns-

wick (Harrington, Can. Ent, XXIV, 1891, p, 112) , In Crotch’s

key (Trans, Am, Ent, Soc, V, 1876, p. 248) it runs to limhatus

Say and vinctus Weber of the subgenus Lichnocarahus. From

these it may be distinguished by possessing only two entire and

three interrupted elytral costae,

Carabus (Archicarabus)nemoralis Mull.

This Palaearctic species has been known in Seattle, accord-

ing to Professor Trevor Kincaid, since about 1909 and is now

our commonest large carabid. It has a wide distribution in North

America, Leng (Cat, Col, Am, n, of Mex. 1920, p, 45) records

it from New Brunswick, New Jersey, and New York. I have

specimens in my collection from Ontario (Toronto, 1921), Massa-

chusetts (Boston, 1921), and Michigan (Ann Arbor, 1924). Gib-

Ent. I, 1924, p. 78) records it from California (San Francisco,

1919). It belongs to the same subgenus as tcedatus Fab., from

which it is most readily distinguished by its more robust form

and the violaceous tinge of the base of the pronotum.

Monillipatrobus punctatus Hatch, gen. et sp. nov.

Monillipatrobus gen. nov. A new genus of Patrobini. Metaepi-

meron not attaining mesocoxa. Head with two setiferous punctures

above eye, feebly constricted behind eyes, basal sulcus feeble but

evident. Mandible with a single setiferous puncture towards distal

portion of scrobe. Antenna less than half the length of the body,

about as long as head and pronotum, with the segments from the

distal portion of the basal segment more or less densely setiferous,

submonilliform, the segments from the base to the apex respec-

tively 1-2, 4-5, 1-2, 5-7, 5-6, 5-6, 5-6, 5-6, 5-7, 5-7, 5-12 as wide as

long. Abdominal segments entirely corneous. Mesoepimeron broad as

compared with Diplous (Platidius) . Maxillary palp with last seg-

ment truncate, longer than penultimate; galea with two segments

subequal. Integuments densely punctate. Pronotum with basal

impressions foveiform, margin not incised in front of hind angles.

Elytra incompletely margined at base. Metacoxee contiguous.

Type: M. punctatus sp. nov.

Distinguished from Patrohus, Diplous, and Patrohoidea Van-

Dyke (Pan-Pac. Ent. II, 1925, p. 67) by its punctate integu-

ments and submonilliform antennae, from Patrohoidea by its

truncate, not acute, terminal palpal segments. It has the flattened

pronotum of Diplous and the deep basal impressions of Patrohus,

in which respects it resembles Patrohoidea.

Monillipatrobus punctatus sp. nov. Length 5. 6-6. 4 mm. Black,

legs and antennae rufo-piceous. Above and below coarsely mod-

erately densely punctate. Head shining, constricted behind, the

constriction more densely punctate, the neck behind the groove

impunctate. Pronotum feebly alutaceous, over four-fifths as long

as wide, broadest about apical third, base about six-sevenths as

wide as apex; side margin with three long setae, one at hind angle

and two in front of middle; side margins narrow, arcuate in front,

sinuate behind, hind angles obtuse, anterior angles rounded; basal

impressions deep, foveiform, connected by a shallow transverse

impression that is interrupted by a pair of longitudinal carinae,

one on either side of the median line ; median line extending almost

from base seven-eighths of way to apex, somewhat wider and more

impressed behind and separated from transverse impression by a

distinct carina on either side; disc flattened; anterior transverse

impression vague, scarcely more punctate than rest of surface.

Elytra widest just behind middle, more strongly alutaceous, octo-

impresso-crenulato-punctato-striate, the striae confused and obso-

lete towards extreme apex, the intervals punctate, the third inter-

val with two setiferous punctures at apical 15% and basal fourth,

the marginal stria with six long and numerous shorter setae, the

long setae divided into a subhumeral and a subapical group. Venter

alutaceous, punctate. Male with, and female without, the basal

three protarsal segments dilated and spongy pubescent beneath.

Type, male (Seattle, Wash. IV-25-1930) and allotype, female

Wash.) in 0. B. Johnson collection.

TrECHUS (s. str.) OBTUSUS Er.

This Palaearctic species, not previously recorded from North

America, was first taken by Professor Kincaid in Seattle in 1927.

I take it in abundance in the grass right along the side of my

house. It may be distinguished from our native species by the

absence of basal impressions on the pronotum.

Pterostichus johnsoni Ulke.

Described (Ulke, Ent. Amer. V, 1889, p. 50; Piper, Proc.

Ent. Soc. Wash. XIII, 1911, p. 62-64) from Mehama, Oregon,

from wet moss on boulders and in gravel in the spray of water

falls. Piper (l.c.) took another specimen at Horsetail Ealls,

Oregon. I have an extensive series from Green River Gorge

(King Co.), Washington, taken in the gravel of talus slopes

constantly wetted by the spray of falls coming over the rim of

the gorge as well as under rocks by streams fed by the same falls.

This species is so unlike any of the other American species of the

genus that I propose for it a new subgenus, named in honor of

its discoverer.

Subgenus Orsonjohnsonus Hatch, nov.

Metaepisternum shorter than wide; elytra with from three to

six dorsal punctures on both third and fifth intervals, the inter-

vals interrupted behind each puncture; side margin of pronotum

with a single seta; distal tarsal segment without hairs beneath.

Type : Pterostichus johnsoni Ulke.

where it is now abundant. Additional specimens have been seen

from Puyallup and Tacoma (1930) and Mt. Vernon, Green River

Gorge, and Robe, Washington, (1931), as well as Marylhurst

near Portland, Oregon (1931). The species is very common in

Europe, where there is a single record (Horner, Entomologist

XVII, 1884, p. 238-239 [^melanarius of it eating straw-

berry fruit. Such a habit must be very unusual, and we have

no evidence of any such in Washington. Omaseus may be dis-

tinguished from Melanius {Pseudomaseus Chaud., Omaseus Lee.,

Casey, and Leng nec Steph.), the American subgenus to which

it is apparently most closely related, by the presence of one or

two setae on either margin of the ventral surface of the last tarsal

segment.

Platynus (Paragonum) belleri Hatch, sp. nov.

Above shining aeneous or virido-aeneous. Head impunctate;

antennae black, pubescent from apical half of third segment; head

through eyes wider than apex of pronotum. Pronotum nearly three-

fifths as long as wide; side arcuate, feebly oblique behind; margin

reflexed, narrowly so in front, more widely so behind; the foveas

of hind angles large, their outer edge formed by the reflexed mar-

gin ; pronotum smooth, impunctate, except for the side margin and

the basal foveas which are densely rugose; mid-dorsal impressed

line attaining neither base nor apex, crossed by an evident im-

pressed line toward apex. Elytra very finely microreticulate with

evident humeri, very feebly wider behind middle; the strias im-

pressed, finely punctate; the first (sutural), third, fifth, and

seventh interstrias more or less densely set with coarse seta-bear-

ing punctures, the second inters tria with from four or five to a

dozen similar punctures, the fourth interstria rarely with one or

two punctures. Venter and legs viridescent, shining, finely alutace-

ous, impunctate; second to fifth visible abdominal sternites with

single seta-bearing punctures on either side of the' middle towards

the hind margin. Protarsal segments feebly dilated and squamose

beneath ( ,? ) or unmodified and simply setose beneath ( $ ) . Length

6.5 mm.

HATCH— NOTES ON CARABID^

121

Named in honor of Mr. Jack Beller, who first brought the

species to my attention in 1928. Though he searched diligently

in similar situations in other local bogs Mr. Beller was unable

to detect this interesting species anywhere but in the one bog,

which is no more than an acre or so in extent. The color of the

beetles matches so closely with that of the sphagnum mat that

they are difficult to detect until one has had his attention called

to them. P. helleri is separated from all other Nearctic species

of Plotynus with which I am acquainted, as well as from other

species of the subgenus Paragonum, by the coarse punctation of

the alternate elytral interstriae.

In the light of the present species the four subgenera of

Platynus Bon. which Casey (Mem. Col. IX, 1920, p. 5, 99) united

under the term “Agonum Bon.” may be more adequately defined

as follows:

A\ Pronotal fovea obsolete, the pronotum towards the posterior

angles evenly concave; form broader; Cal Leucagonum Csy.

A". Pronotal fovea evident; form narrower.

Pronotal fovea small, distant from margin of pronotum

C\ Dorsum brilliant metallic Agonum Bon.

C'. Dorsum black, rarely feebly 2 &rieo\x^....Melanagonum Csy.

B'. Pronotal fovea large, concave, formed externally by the

more widely reflexed side margin Paragonum Csy.

Platynus (Oxypselaphus) pusillus Lee.

This species is distinct from the Palaearctic ohscurus Herbst.

The two species may be distinguished as follows:

A\ Basal impressions and base of pronotum coarsely densely

punctate; elytral striae crenately punctate; elytral intervals

impunctate; length 5-6 mm.; Europe, (?) Siberia, {oblongus

Schaum, taeniatus Payk., pallidulus Chd.) ohscurus Hbst.

A'. Basal impressions of pronotum nearly impunctate; base of

pronotum coarsely sparsely punctate; inner elytral striae im-

punctate, outer ones finely punctate; elytral intervals with

setiferous punctulae; length 6-7 mm.; Washington and Canada

to New York and Illinois. (Stomis americanus Lee. nec Lap.;

ON A NEW EYELESS SPIDER OF THE FAMILY

LINYPHIID^ FROM POTTER CREEK

CAVE, CALIFORNIA

BY RALPH V. CHAMBERLIN

The spiders reported upon in the present paper were collected

in Potter Creek Cave by Mr. W. J. Sinclair in 1903 and were

transmitted to me for study by Prof. C. A. Kofoid. One of the

specimens represents a widespread species of Xysticus. This

is not normally a cavernicolous form and its occurrence in Potter

Creek Cave was probably casual, spiders of various types often

being found in caves near the entrance. The other specimens of

the collection, however, represent a species which is apparently

a wholly cave-dwelling form as indicated especially by the com-

plete absence of eyes, in which respect it suggests another mem-

ber of the same family, Anthrobia mammouthia, of the Mam-

moth Cave. The blind species of the present collection repre-

sents a new genus closely allied to Linyphia in habitus and gen-

eral structure. Several cave-inhabiting species of Linyphia are

known in which the eyes show various stages in reduction, the

anterior median eyes being the first to show the effect of life

in the dark. Members of the Linyphiidae, many of which normally

seek shade and moisture, are especially likely to be represented

in any permanent spider fauna occurring in caves remote from

the entrances.

Linyphiid^

Tuganobia Chamberlin, gen. nov.

Cephalothorax broad and depressed, the pars cephalica but little

elevated; eyes not developed; clypeus broad, slanting forward from

above; upper margin of furrow of chelicerae with three well-de-

veloped teeth, the lower unarmed; palpi of female with well-de-

veloped claws which are pectinate over middle portion as in claws

of legs; palpal organ of male similar to the ordinary type shown

by Linyphia’, embolus long and slender, curved; legs long and

slender, setose but lacking true spines; paired claws with a series

of teeth over middle region.

Tuganobia potteria Chamberlin, sp. nov.

General color of body and legs throughout pale yellow, with

carapace, sternum and coxee of legs more or less dusky; legs and

abdomen wholly unmarked excepting that the dorsal vessel may

show through the abdomen as a median longitudinal stripe.

Cephalic eminence dorsally rounded, low, set off by a depression

separating it from clypeus. Clypeus slanting forwards to base of

chelicerae. Cephalothorax widely truncate behind, the pars thora-

cica broad and laterally rounded, depressed (fig. 1). Two upper

teeth of superior margin of chelicerae long and sub-equal, the

lowermost smaller.

Legs long, setose but unspined. Paired claws typically with five

teeth which decrease in length proximad as shown in fig. 2.

Abdomen high anteriorly, pointed behind, with spinnerets car-

ried at end in caudoventral position, Linyphia-like.

Epigynum of female a well-chitinized plate without distinct

processes (fig. 3).

Palpal organ of male large and freely exposed, the embolus

forming a single coil curving back widely over paracymbium and

about base and opposite side (fig. 4).

While best known from the northeastern part of the United

States, this species has been taken previously in California as

the palpus is shown in lateral view in fig. 5. In coloration, eye

relations, and spining of legs, the specimen is typical.

CAUDELL— A NEW SIALID

NEOHERMES INFUSCATUS, A NEW SIALID

FROM CALIFORNIA

BY A. N. CAUDELL

Bureau of Entomology

United States Department of Agriculture

The species here described was recently received for deter-

mination from Charles F. Harbison of the University of Cali-

fornia, at Berkeley, California. It is at a glance distinguishable

from other Nearctic species of the genus by the almost uniformly

black color of the wings. Recognizing it as belonging to the

genus Neohermes, the author thought it might be the N. cali-

fornicus of Walker. But being in doubt about this he sent one

of the specimens to Mr. Nathan Banks, who pronounced it a

new species undoubtedly distinct from calif ornicus. It is de-

scribed as follows:

for the genus Neohermes in Banks’ key to the genera of Coryda-

linae.* The general color is deep brownish black' to dead black, the

wings uniformly colored, without bands or noticeable maculation,

except that brownish black individuals show some small obscure

lighter areas, especially on the fore wings and the apical portion

of the anterior field of the hind wings. Abdomen beneath, except

apically, dull brick-red in color, above similarly colored but less

distinctly so; clypeus, labrum, and outer surfaces of the mandibles

light or reddish colored and the base of the head more or less

obscurely tinged with reddish; legs and antennae uniformly black;

ocelli distinct, light yellowish in color, and forming a triangle but

little broader than high.

The measurements of the female are: Length of body from

front of head to tip of abdomen, 20 mm. ; antennae, about 16 mm. ;

fore wings, 33 or 34 mm.; hind wings 3 or 4 mm. shorter than the

fore wings; width of wing, both fore and hind pair, a little more

than 10 mm.

The male, which lacks the abdomen, is somewhat smaller than

the female, the length of the anterior wings being 30 mm.

Described from one male, without antennas or abdomen, and

three females taken by Mr. Arthur S. Harrison, in broad daylight

flying about blooming California buckeye trees growing in

ADDITIONS TO THE COCCINELLIDAE OF ALASKA

BY F. T. SCOTT

Visalia-, California

Through the kindness of Mr. R. E. Barrett, of Saticoy, the

writer has recently obtained a number of . species of Coccinellidae

collected by Mr. Barrett, in the summer of 1928, in Alaska.

Mr. H. C. Fall, (Pan-Pacific Entomologist, July, 1924), lists

a number of species. The following are in addition to that list:

Coccinella tricuspis Kby. Ft. Yukon, 6-23-1928.

Hippodamia 5-signata Kby. Eagle, 6-18-1928.

Adalia frigida Schn. Circle, 6-21-1928.

Adonia amoena Paid. One specimen from Eagle, Alaska,

6-18-1928, one from Kirkman Creek, Y. T., 6-13-1928. These

specimens of Adonia amcena were determined by Dr. Th. Dobz-

hansky, of the California Institute of Technology, an authority

on Siberian Coleoptera. I do not believe that this species has

ever been reported from North America before.

Ceratomegilla ulkei, Cr., 3 specimens. While these were col-

lected in Yukon Territory before Mr. Barrett reached Alaska, I

believe they are deserving of a note here. This is a very rare

species unknown to both Casey and Leng. Two of the specimens,

both females, agree perfectly with the description, except that

the third antennal segment is not dilated. The third specimen,

a male, is atypical in ornamentation, but has the dilated third seg-

ment. These specimens were sent to Mr. H. C. Fall who kindly

offered to compare them with the Crotch type at Cambridge, but

this species was found to be represented there only by a drawing

of an elytron. It would appear, from this, that the dilated third

antennal segment is a male character, and not a good generic

character.

Two members of this genus, Gastrodes abietis (Linn.) and

ferrugineus (Linn.), have been reported from coniferous trees

in Europe. The new species herein described was found very

abundantly in mature cones in which the seeds were just being

shed and in which there was a great deal of resin or pitch. The

occurence of many nymphs of various stages indicates that the

species was breeding under these conditions. No specimens had

ever been found during previous years of collecting nor, upon

diligent search, were any specimens later found to occur in the

foliage or in old cones of previous seasons.

PRENTISS— FORFICULA

129

REGENERATION OE THE CERCI IN FORFICULA

AURICULAR! A L.

BY R. W. PRENTISS

The discovery of regenerated cerci on the European earwig,

Forficula auricularia L. was made in a peculiar manner.

While the writer was working in the Earwig Parasite Labora-

tory in Portland, Oregon, during the summer of 1931, large num-

bers of earwigs were handled each day during the routine of

“hand parasitizing” them with larvae of the Tachinid fly, Digo~

nichceta setipennis Fall.

The “hand parasitizing” procedure used was simple. It con-

sisted of picking up slightly chloroformed earwigs by the cerci

with small forceps in such a manner that the earwig might be

brought in contact with the parasite Digonichceta larvae contained

in small glass tubes. A parasite would almost immediately attach

itself to the earwig, which was then removed to a safe container.

During this process one or more cerci would often break off, par-

ticularly in the case of the last nymphal instar of the earwig when

the cerci are more slender and easily broken.

In order that none of the costly parasites be wasted on ear-

wigs which might die as a result of the wound left by the

broken cerci, a few of these injured earwigs were kept to see

how long they would live. It was found that not only did they

all live but that the last instar nymphs during their change to

adult grew new cerci to replace the old.

A. Normal female cerci. B. Left cercus of female regenerated.

C. Both cerci regenerated. D. Normal male cerci. E. Right cercus

of male regenerated.

130

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 3

This was so interesting that a series of experiments was con-

ducted with numbers of the nymphs from which one or both

cerci had been removed. Legs and antennae were broken from

other nymphs in order to determine whether they too, might not

be regenerated. As previously observed, the nymphs on changing

to adults developed new cerci. Legs and antennae did not grow

back. Adults failed to grow new cerci, although two experiments

were made to test this point.

The regenerated cerci are not normal but are stunted and mal-

formed, The accompanying drawing compares the normal cerci

of male and female earwigs with the regenerated cerci. It will

be noticed that the new cerci are much like those of the adult

female in that they are fairly straight. This may have been partly

the reason for the conclusion reached by Morgan in an article

in the Proceedings of the Indiana Academy of Science, Vol,

XXXVI, 1926 (1927), pp. 331-333. He believed that these forms

which he accidentally discovered, were gynandromorphs such as

have been reported from other insect orders.

This conclusion, in view of the above observations and the

fact that the regenerated cerci bear little resemblance to the nor-

mal female cerci, is probably wrongly drawn.

The writer can make no definite explanation for this interest-

ing growth on the part of nymphal earwigs but suggests that

possibly the cerci develop entirely from the chitinous covering

which is thrown off during each moult, and therefore grow from

the newly developing epidermis. Such a conclusion seems to be

borne out by the fact that adults are unable to regenerate the

cerci,

ABSTEACT

Ith as been found that regeneration of the cerci of the Euro-

pean earwig, Forficula auricularia L. is not rare. The resulting

condition was formerly thought to be gynandromorphic by at

least one author.

LINSLEY— A NEW LONGICORN

131

A NEW LONGICORN BEETLE FROM CENTRAL AMERICA

(Coleoptera, Cerambycidge)

BY E. GORTON LINSLEY

Oakland, Calif.

The genus Phrynidius is typically Central American. Of the

four previously described species, one is from Mexico and the

three remaining are from Guatemala. These peculiar little

beetles, unlike most longicorns, are usually found at high alti-

tudes under rocks and stones. The following species agrees in

all essentials with the other known species:

Phrynidius armatus Linsley, new species

Elongate, suboval, piceous; vestiture squamose, fuscous. Head

about as broad as long; eyes narrow, deeply emarginate, coarsely

granulated; antennal tubercles short, verticle, contiguous at base,

separated by a narrow groove apically; antennae three-fourths as

long as body, sparsely clothed with short, curved, scale-like hairs

in addition to the darker scales; scape incurved, one-third longer

than third segment, the latter one-third longer than the fourth,

remaining segments distinctly shorter, subequal, with exception of

the eleventh which is longer than the tenth. Prothorax longer

than broad, covered with small irregular tubercles; disc very con-

vex, with larger unequal tubercles; punctation coarse, sparse.

Elytra oval, not quite twice as long as prothorax, less than a third

longer than broad; elytral tubercles arranged in two poorly de-

fined longitudinal rows, the inner of which extends from base to

apex and the outer from base to apical third with an, interruption

at the middle; larger tubercles interspersed with smaller ones;

punctation coarse, somewhat obscured by scales. Body beneath

finely punctured, densely clothed with fuscous scales and a few

longer, pale, scale-like hairs. Legs sparsely, finely, punctured;

tibise at apex with a fringe of equal yellow spines, tarsi clothed

beneath with dense yellow hairs. Length 9 mm., breadth 4 mm.

indebted to Mr. E. P. Van Duzee of the latter institution for the

opportunity of studying this interesting species.

In the above series, the relative proportion of the various

segments of the antennae is very constant, confirming the validity

of this character for use in the separation of species. In Phry-

nidius echinus and P. singularis, the third antennal segment is

distinctly longer than the scape. In P. armatus, P. asper, and

P. incequalis, the third segment of the antennae is shorter than

the scape. From the latter species, P. armatus differs in having

the antennae in both sexes three-fourths as long as the body, and

from P. asper it differs in having the third segment of the an-

tennae one-fourth longer than the fourth segment. P. asper is

stouter and more oval than either P. armatus or P. incequalis.

A Note on Cosmotoma sertifer Serv.

In 1835, Serville described Pogonocherus sertifer from Brazil.

Later v/riters placed the species in the genus Cosmotoma where

it properly belongs. However, in the Coleopterorum Catalogus,

pars. 74, 1923, Chr. Aurivillius cites it twice: on page 334 as

Pogonocherus setifer and on page 419 as Cosmotoma sertifer.

Plavilstshikov, in his additions and corrections to the Coleopte-

rorum Catalogus pars 73 and 74 (Encyc. Ent. B. I. Col. 1927, p.

59) proposes the new name Pogonocherus hrasiliensis for P. seti-

fer which had already been used for a European species by

Muller (Zool. Danm. Prodr. 1776, p. 92), Since Serville’s orig-

inal spelling was sertifer not setifer, Plavilstshikov’s new name

is unnecessary. The corrected synonymy of the species is as fol-

lows:

BALL— NEW ACHILID^

133

SOME NEW WESTERN LEAFHOPPERS OF THE FULGORID

FAMILY ACHILID^

BY E. D. BALL

University, Tucson, Arizona

This interesting family of moth-like insects feeds, as far as

known, in the nymphal stages at least, on fungi growing on

decaying wood. One would naturally expect to find a group

with such food habits largely confined to the forest regions of

the humid East; instead they are much more numerous in species

and diverse in form in the extreme Western and Southwestern

regions. It is true that they are largely confined to the moun-

tains of this region but a considerable number come from the

chaparral or elfin forest type of cover of these mountains.

Epiptera shoshone Ball, n, sp.*

Form of henshawi but smaller and with shorter elytra; front

dark brown and cream, mesonotum dark brown, elytra silver.

Length 8 mm., width across folded elytra 4 mm. Vertex about

quadrangular in the female, a little longer in the male, the apex

slightly rounding; elytra resembling woodworthi in shape, even

broader and shorter, the stigmal area without the two transverse

veins of henshawi and the anal cell with two transverse veins in-

stead of one as in that species.

Color, silvery iridescent, the vertex slightly orange with a dark

border; pronotum griseus; mesonotum dark brown, almost black

with three faint spots in a triangle at the apex; elytra silvery

with a pair of dark spots on disc on either side, a longer one on

the stigma and some irregular ones at apex; front rich creamy,

the basal third dark brown or black, the band running back on

the pleural pieces; clypeus and below* smoky brown.

Holotype 9 and allotype $ Shoshone Nat. Forest, Wyo.,

Aug. 15, 1927 (H. H. Knight) . The short broad silvery elytra

renders this a strikingly distinct species.

Uniptera Ball, n. gen.

Resembling Epiptera in size and form but with a head more

nearly like a Catonia of the producta group but less elongate.

Strikingly distinct from these genera in the extremely ampliated

costal area which is twice as wide across the middle of clavus

as it is at the stigma.

* All types in the collection of the author.

134

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 3

Head small and inconspicuous, the eyes much flattened against

the side of head as in Epiptera pallida. Vertex triangular, the

lateral carinse slightly roimding to the apex, the base deeply

angularly excavated so that its median length scarcely equals the

basal width; median carina broad and tumidly elevated posteriorly,

forming a fovea on either side. Front extremely long and narrow

only slightly widening towards the truncate apex, two and one-

half times as long as its apical width, the front and clypeus ele-

vated from face. In profile very convexly rounding with a very

obtuse angle with the vertex above instead of flat with an acute

angle as in Epiptera. Pronotum very small and narrow, not quite

twice the width of the eyes and less than half as wide as the dis-

tance across the closed elytra; very short scarcely more than a

collar except for the tumid, triangular central tablet which extends

into the excavated head. Elytra very broad in front, roundingly

narrowing behind. Venation simple, resembling Epiptera, the

stigma set off by two oblique nervures.

Type of the genus Uniptera ampliata n. sp.

Uniptera ampliata Ball, n, sp.

Superficially resembling a small pale Flatoides punctata but

without the transverse veins along costa. Still more closely re-

sembling CEcleus snowi but with a widely different head and

elytra overlapping posteriorly. Broad and short with a narrow

head, pale creamy with three black points in a transverse line

just before the forks of the primary nervures on each elytron.

Length $ 8 mm., width 3.5 mm.

Structure of the genus; pronotum almost straight along the

posterior margin, the lateral carinae following the margin of the

triangular projection. Mesonotum extremely short and broad, the

lateral carinse distinct, the median one obscure. Costal area of

elytra occupying over one-third the breadth at the widest part

opposite the rows of dots, then rapidly roundingly narrowing in

front and slowly and regularly narrowing posteriorly to the broad

stigma.

Color: Vertex and face creamy tinged with orange especially

around the eyes; rest of dorsum pale creamy the nervures con-

colorous, a black spot outside the claval suture just in front of

the fork of the/ cubitus, a second spot outside the medius and just

before the subcosta-radius fork, a third equidistant spot in the

same line in the costal area. Below pale, the venter smoky; under-

up Mt. Wilson, June 21, 1909. This is such a strikingly dis-

tinct and interesting form that it warrants description from a

single sex.

Catonia fumida Ball, n. sp.

Resembling maculifrons and lineatocollis but longer, nar-

rower, and less maculate. Dark smoky with light carinae and

nervures in sharp contrast. Length 5 mm.

Vertex about as in maculifrons slightly longer than wide, nar-

rowing apically, meeting the front in a definite carinate angle,

front proportionally much narrower than in maculifrons. Elytra

proportionally much longer and narrower, definitely narrow and

parallel-margined in repose. Male abdomen with a triangular

apical projection as long as its basal width and one-third the

length of the ear-like plates.

Color, almost uniform dark smoky above with the carinas, the

posterior margin of pronotum, a pair of stripes between the carinae

on mesonotum and the nervures white, in sharp contrast. Face

and below creamy or old ivory; a broad apical and three narrow

basal bands on the front widely separated into spots by the ele-

vated median carinae, black.

Holotype, female, allotype, male, and two pairs of para-

types. Huachuca Mts., Aug. 2, 1931, a female Sabino Canyon,

July 14, 1932, and a male (labeled) Tucson, Sept. 1, 1929. All

taken in the mountains of southern Arizona by the author. From

maculifrons this species may be readily separated by the long

uniform colored elytra, the narrow face and the fact that the

upper bars on the front in that species tend to coalesce while in

fumida they are reduced to small distinct spots. The long taper-

ing apical projection in the male will separate it from both

lineatocollis and maculifrons where this projection is broader

than long and truncate.

Catonia arbutina Ball, n. sp.

Resembling nava in size and form, broader than hicinctura,

much darker than either. Fuscus brown with white maculations

and cross nervures. Length of 2 5 mm.

Vertex slightly more acutely carinate than in nava with corre-

spondingly larger lateral fovese. All carinae of dorsum and the

claval veins much elevated, acute. Elytra with the venation of

the pattern of nava, the fork of the subcosta widening apically

136

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 3

and obliquely truncate. Male abdomen ending in a long bifurcate

process that is shorter and broader than in nava and the plates

are not as long or as strongly oblique.

Color, dark smoky brown, the lateral portions of pronotum

white with four black spots, the nervures interrupted with white,

the cross nervures white and the costal margin pale interrupted

with quadrate dark areas. Front dark brown or black with a

definite parallel margined white band.

Holotype, female, allotype, male and two female paratypes,

taken in the Santa Rita Mts., Sept. 29, 1929 (labeled Tucson),

one female Chiricahua Mts. Aug. 23, 1932, and one female

Huachuca Mts. Oct. 9, 1932. All taken high in the mountains

of southern Arizona by the author. The dark color alone will

separate this from the others of the nava group.

Catonia indella Ball, n. sp.

Resembling succinea in form and structure; smaller with a

narrower vertex, dark smoky brown with three light areas on

dorsal line. Length female 6 mm.

Vertex distinctly narrower than in succinea, each lateral tablet

nearly twice as long as wide, the pronotum slightly shorter than

in succinea,’, the lateral carinee definite and parallel instead of

widely diverging and becoming obscure as in that species. The

central tablet even narrower than in producta, narrower than the

mesonotal tablet which is slightly expanded posteriorly. Elytra

extremely long and slender, the outer claval nervure tied to the

suture near the middle and twice at the posterior angle as in

products, the nodal cell an elongated egg-shape as in succinea.

Front long and narrow, the sutures between front and clypeus

strongly oblique near the margin then obscure.

Color, dark smoky brown above with the caringe light. The

front creamy above shading out to smoky on clypeus and black

below. A pair of round black spots on the lateral foveate areas

above. Pronotum with the central tablet dark, the rest pale with

four black spots on each side. Apex of mesonotum and an area

adjoining, pale, including the ivory bases of the inner claval ner-

vures, the apices of the outer clavals, an area on the inner clavals

and the membrane between, ivory white. The cross nervures

apically ivory white' and an area beyond clavus pale.

Holotype, female, taken in mountains above San Louis Obispo,

Calif., June 22, 1931, by the writer. This is strikingly distinct

in color and while it belongs with producta in having the narrow

pronotal tablet its vertex is much shorter.

BALL— NEW ACHILID^

137

Catonia brunnella Ball, n, sp.

Resembling rubella in form and structure. Longer, darker,

with an extremely long pronotum. Smoky testaceous, the slightly

hyaline elytra with smoky apical spots. Length female 6 mm.,

male 5 mm.

Vertex scarcely as long as wide but little longer than the pro-

notum, base of front extending beyond vertex especially at sides,

front short, much narrower than in rubella, short, convex, coni-

cally pointed, highly polished, with the lateral margins parallel.

Pronotum very little produced between the eyes, very long, twice

the length in rubella, the lateral margins longer than on the

median line but lacking the sulcus of Epiptera. Elytra not as

long and narrow as in indeila but longer than in rubella and its

allies; venation similar the nodal cell much longer and lacking

the triangular division at base. Male abdomen with an attenuate

triangular median pro jection that is longer than the ultimate seg-

ment and two-thirds the length of the widely separated strap-

shaped plates that are apically rounded and beset with coarse hairs.

Color, uniform, light smoky brown, the face and carinee uni-

colorous, nervures a trifle darker, a smoky band around apex of

elytra broken into spots by the light margined apical nervures.

Holotype, female, Huachuca Mts. Oct. 9, 1932, allotype,

male, and paratype male taken in the Santa Rita Mts. (labeled

Tucson) Sept. 29, 1929; all taken in Arizona by the writer. This

is a strikingly distinct species in the extremely long pronotum

and the male genitalia. It is near the body color of necopina

but more than twice its size.

Catonia constellata Ball, n. sp.

Resembling necopina in form and color, slightly broader.

Pale cinnamon the nervures bordered with ivory dots. Length

4 — 4.5 mm.

Head including eyes a half circle, the sharply carinate vertex

not reaching the apex. Vertex broader than long. Front convex

slightly conical, highly polished, carinate towards apex, slightly

expanded apically with the lateral carinse almost foliaceous. Pro-

notum short, not over half the length of head as in necopina.

Elytra broader than in necopina or costata with a simpler vena-

tion and a long stigma. Male abdominal projection about equi-

laterally triangular, the apex bluntly rounding, less than half as

long as the ultimate segment. Plates broadly, obliquely spoon-

shaped.

138

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 3

tudinal nervures concolorous, bordered with ivory dots or irreg-

ular transverse dashes; cross nervures ivory.

Holotype, female, allotype, male, and one female paratype

taken by the writer at Colfax, Calif., June 8, 1909. Strikingly

distinct in this group by the ivory dots.

Some Observations on the Swarming of Melanophila

In previous numbers of this Journal, Dr. E. C. Van Dyke

recorded the swarming of Melanophila consputa Lee. at an oil

fire^ near Coalinga, Calif., and at a Sugar Refinery^ in San Fran-

cisco. This peculiar habit has been witnessed by the writer on

numerous occasions at grass or brush fires in the hills near

Oakland, Calif. The beetles were greatly stimulated and very

active, flying into the smoke and running rapidly about over hot

coals and smoldering embers. They usually remain in the vicinity

for several days after the fire has been extinguished and may

be captured as they fly about the ashes and charred wood that

remains. In the region near San Francisco Bay the species

involved are M. consputa Lee. and M. atropurpurea Say. The

swarming usually takes place in September and October and

only an occasional specimen of either of these species may be

captured earlier in the year.

In June, 1932, however, the writer found large numbers of

Melanophila about the street lights at Douglas, Arizona. In an

effort to account for their presence, it was concluded that they

had been attracted to the city by the acrid fumes of the large

smelter plant for which Douglas is noted. The beetles must have

been drawn from a great distance as there is no coniferous for-

est within fifty or sixty miles. The species attracted in this man-

ner were M. notata Cast., M. consputa, and M. acuminata DeO.,

with the latter species in predominance.

It is interesting to note that all of the species mentioned

above are of the more elongate, slender type of Melanophila.

At no time has the writer ever observed any of the short, broader

species {M. gentilis, M. intrusa, M. californica, or M. drum-

mondi) swarming in this manner. — E. Gorton Linsley.

MOULTON— A NEW THRIPS

139

OLIGOTHRIPS OREIOS A NEW GENUS AND SPECIES OF

THRIPS BELONGING TO THE FAMILY

OPADOTHRIPID^ BAGNALL

BY DUDLEY MOULTON

There are three genera already recognized in the family

Opadothripidce Bagnall, (Superfamily Heterothripoidea Bag-

nall), namely: Opadothrips Priesner, fossil, Holarthrothrips Bag-

nall from France and Adiheterothrips Ayyar from India. The

species described here is the first in this family to be recorded

from North America.

The superfamily is characterized as follows: antenna with nine

segments, all freely movable; maxillary palpus with three, labial

palpus with two segments; fore tarsus with a hook-shaped claw;

wings narrowed and pointed at ends; ovipositor curved downward.

The family Opadothripidse is distinguished by the lanceolate

shaped, two-segmented sense cones on antennal segments three

and four.

In his description of the genus Holarthrothrips, Bagnall

states: antennal segments “three and four markedly annular,

broadened outwardly near apex to seat a special type of lanceo-

late sense-cone as in Opadothrips', the following (5-9) narrower,

progressively less distinctly annular, long and cylindical”. These

characters hold also for Adiheterothrips.

The genus Oligothrips includes the characters enumerated

above for superfamily and family but may at once be separated

from the other three genera by the shape of the antennal segments

which are relatively shorter, elongate-ovate rather than cylindrical

in shape and with terminal segments sub-globate. It resembles

Holarthrothrips in having well developed spines on the pro-

thorax; these are reduced to setae in Adiheterothrips.

Oligothrips oreios Moulton, n. sp.

Female holotype: Color of body, antennee and legs dark brown,

with third antennal segment, fore tibiae and tarsi yellowish; wings

light brownish; crescents of ocelli orange.

Total body length 1. mm.; head length .09 mm., width .130

mm.; prothorax length .123 mm., width .176 mm. Segments of

antenna: length (width) I, 23 (24); II 36 (23); III, 43 (18);

IV, 36 ( 20); V, 33 (16); VI, 33 (16); VII, 26 (16); VIII, 20

(13) ; IX, 16 (10) ; total 270 microns. Length of spines; on an-

terior angles of prothorax, 23 microns; on posterior angles, inner

140

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 3

60 microns, outer 53 microns; inner pair on posterior margin,

33 microns.

Head wider than long. Eyes prominent, pilose; ocelli well de-

veloped. A pair of small sets behind each ocellus and series of

four behind each eye, the second and fourth longest. Antennal

segments three and four elongate ovate, only slightly enlarged to-

ward tips, not conical or cylindrical; sense cones on these segments

lanceolate, two-segmented, short.

Prothorax longer and wider than head; setae on anterior

angles directed forward; a series of seven on either side along

posterior margin, one and three on angles longest, inner pair (six

and seven) with base of seven close but anterior to six. Pore

tarsus armed with a strong hook-shaped tooth. Wings broad at

base, otherwise long, narrow, pointed at tips; costal with 28 spines

and well developed fringe, fore vein with 21 and hind vein with

17 regularly placed spines.

Posterior margin of abdominal segments, including eighth, with-

out fringe hairs.

Type material: Male holotype, 8 female paratypes taken in

blossoms of madrone and manzanita, April, 1932. All types in

author’s collection.

Type locality: Grass Valley, Nevada County, California.

We were recently asked to study the present collection and

among the one hundred and thirty-five specimens a number of

interesting records have been found. Thirty-nine species are

here considered, none of which are new. Two synonyms are

suggested. We wish to thank Mr. E. P. Van Duzee for the oppor-

tunity to study this material.

The limb annuli are almost obsolete in the Kobe and Nanking

adults, very weak in the Kagoshima male and moderately pro-

nounced in the others. The antennal joints are usually as char-

acterized for pallipes Shiraki and we feel that that name may well

prove a synonym, as stali Dohrn and ininuta Caudell already

have done. The macropterous condition is again recognized with

interest.

smaller and, unlike that specimen, with a trace of meso-distal

(all brachypterous).

Chelisochella superha (Dohrn) Borneo, (E. Mjoberg), 1

(moderately macrolabic), 5 2 (macrolabic) .

The female of this species has every appearance of males in

other groups.

Adiathetus shelf or di Burr In 1929 our corrections for this

species were twice at fault. Burr (not Shelf ord) figured the

species in 1900, the male as his synonym hercules, the female

(not a male as he supposed) as shelf ordi.

The specimens in the author’s collection from Pontianak,

Borneo, are a very similar pair, not a macrolabic and a brachy-

labic male as we supposed. The present insect shows much the

same peculiarities as Chelisochella superha in that the specialized

macrolabic forceps of the female resemble the specialization

peculiar to males in other groups. This is extremely unusual

in the Earwigs.

Forficulid^

Anechura japonica (Bormans) Mokansan, Che-Kiang, China,

IX, 22, 1927, (Mrs. Doris E. Wright), 1^.

This specimen has sharp rugose cones, directed dorso-ex-

ternally, above the bases of the forceps. The forceps are mod-

erately and evenly curved with a large acute-angulate lamellate

tooth at end of proximal third on inner margin directed ventro-

internally. The limbs are uniform testaceous with a reddish

tinge. The species looks much like an Apterygida but is de-

cidedly more robust.

Anechura vara (Scudder) Amecameca, Mexico, VI, 6 and 8,

1897, (A. Koebele) ,1^,12.

Taipinia crinitata Shiraki We agree with Shiraki in consider-

ing that his Taipinia, described in 1908, should be recognized.

It is indeed close to Anechura, but the features which be gives

in 1928, the pronotum considerably instead of somewhat smaller

than the head (and in crinitata the spined pygidium), warrant

generic recognition.

NOTES ON PHAL^NID^* (LEPIDOPTERA)

BY FOSTER H. BENJAMIN

The notes in this paper resulted from the identification of

specimens for Mr. Graham Fairchild and for the Museum of

Comparative Zoology. These specimens represented Mr. Fair-

child’s recent collections in Nova Scotia and part of Professor

Thaxter’s collections in Newfoundland in 1882.

One name has been removed from synonymy and is used for

a valid species with another name transferred to it as a synonym ;

one name heretofore considered of specific rank has been sunk

to subspecific status; two names heretofore listed as being of

specific rank have been sunk as synonyms; and three new sub-

species have been described.

The type of perquiritata Morrison is in the National Museum.

A somewhat lengthy bibliography is cited because of the gen-

eral confusion of this species with the closely related speciosa

Hiibner.

Grote (1880) contended that he recognized two species, per-

quiritata and speciosa, and that his name haileyana is a synonym

of the former. In view of this direct statement, and the fact that

the Grote types have probably been destroyed, there seems noth-

ing to do but to accept the synonymy proposed by Grote. The

synonymy proposed by Smith (1890 and 1893) has been ac-

cepted, to date, by all subsequent authors, but is certainly in-

correct in so far as the name perquiritata is concerned. Obviously

Smith did not recognize the existence of two closely related

species until about 1910, when he described the form of speciosa,

which is pale with prominent markings^ as a separate species

under the name of livalis'.

The author has seen some eighteen examples of perquiritata

inclusive of specimens representing all described subspecies.

These possess a more constricted and more irregular reniform

than that of examples of speciosa from Europe, Labrador, and

New Hampshire (in the National Museum). The orbicular tends

to be smaller. Smith pointed out these characters (1910). The

male genitalia have been discussed by McDunnough (1921 and

1928), and males of the two species may easily be sorted by

denuding the tips of the harpes. The tip of the harpe of speci-

^Variety mixta Walker accordingr to Hampson.

^Thanks are due to Miss Augusta Meske and other members of the Ento-

mological staff at Rutgers College for a sketch of the harpe of the type of

livalis, and structural comparison with this type of specimens of perquiritata

and speciosa..

mens of speciosa is lobate, while the similar part of specimens

of perquiritata is bifurcate. Also specimens of speciosa usually

possess an oblique shade from the costa, passing through and

darkening the reniform; whereas this shade in perquiritata is

usually obsolescent.

The type of perquiritata is the only example seen by the

author. It possesses some dark rufous tinting on the median

area of the fore wing and seems intermediate between subspecies

bedded Hampson, a name applicable to specimens with con-

trasting maculation and pale ground similar to variety mixta

Walker of speciosa Hubner, and subspecies partita McDunnough,

from the mountains of Alberta and British Columbia. The latter

has the fore wing heavily and evenly powdered with fuscous,

appearing quite dark, the basal dash and claviform more or less

obsolescent. More specimens from the mountains of New Eng-

land will be necessary to ascertain if either bedded or partita

are the same as perquiritata.

Some years ago a specimen from Mt. Rainier was given the

author by Mr. George P. Engelhardt for the Barnes Collection.

This has been held awaiting receipt of more material. Recently

a second specimen was submitted by Mr. J. F. Gates Clarke.

These seem to represent a separate northwestern race, described

as follows:

powdery appearance, but differing by the fore wing possessing

paler basal, terminal, and subterminal areas, causing the median

the basal black dash is defined; and a strongly marked claviform

is present.

The Hiibner and Moeschler types came from Labrador; the

type of saxigena from Mt. Washington, N. Hamp.; the Walker

type from St. Martin’s Falls, Hudson Bay; and the Smith type

from Yellowstone Park, Wyo.

Labrador specimens are variable both in size and colora-

tion, some being extremely runty while others are as large as

the largest that are in the collection from Mt. Washington and

Ontario. The color difference between imperita and arufa men-

tioned by Smith, and accepted by all subsequent authors as a

specific character, does not hold. The Smith type is somewhat

rubbed, but reddish scales are evident. Another male from

Yellowstone Park, bearing the same kind of labels as the type,

shows practically the same coloration as some specimens from

Labrador. The only distinction which is observed between the

Yellowstone Park specimens and typical imperita seems to be

in size, the former being slightly larger than any in the long

series from Labrador. Alberta and Colorado specimens prac-

tically agree with Yellowstone Park material. In this regard,

Dod (1915) states that the Walker type of discitincta is larger

than Labrador specimens in the British Museum. The genitalia

of imperita and arufa show no differences, and the latter name

seems unworthy of retention. Both Dod and McDunnough have

considered Alberta material as typical imperita. Should subse-

quent authors desire a separate name for the slightly larger

specimens, discitincta Walker would appear to be available and

with priority over arufa Smith.

ANTHOCHARIS SARA BDV., RACE STELLA EDW.

(Lepidoptera, Rhopalocera, Asciidae)

BY J. D. GUNDER

Pasadena, California

Mr. J. W. Tilden of Santa Cruz spent the fore part of July,

1933, in the vicinity of Echo Lake in El Dorado County, Cali-

fornia, and to him goes the credit for re-finding the Orange-tip

butterfly, Anth. sara Stella Edw. unreported in the last twenty

years. He took quite a long series in both sexes in this locality.

Echo Lake is in the eastern and highest part of El Dorado County,

south of Glenn Alpine Springs (Fallen Leaf Lake) which adjoins

Lake Tahoe, and is just off the main highway near the village

of Vade. All this region is immediately south of Lake Tahoe.

Stella was adequately and accurately described by W. H.

Edwards in the Canadian Entomologist (11:87, 1879), from a

series of specimens taken at “Yo Semite” and near Lake Tahoe,

Mr. Edwards knew it to be a high Sierra species and not in any

sense a “variety” or what we might more modemly call a form.

In the original description special mention is made of the lemon-

yellow ground color in both sexes and in all specimens, and this

difference is carefully noted in comparison to reakirtii Edw. and

julia Edw.

In a list of the “Butterflies of the Lake Tahoe Region” pub-

lished in the June, 1910, Entomological News, Mr. R. J. New-

comer reports Stella a rather common diurnal near Glenn Alpine

October, 1933

GUNDER— ANTHOCHARIS

151

Springs below 8500 feet from the middle of May to the last of

July. He mentions that the males have a yellow tinge. Mr. F.

Grinnell and Mr. F. X. Williams also collected in this area,

but neither of these gentlemen go into the matter of specific re-

lationship. The late Dr. Wm. Barnes of Decatur, 111., did not

have enough Stella in his series to see its proper status, never-

theless he accords it a racial position in his B. & McD. Check

List of 1917, following Edwards own lead, and the B. & Benj.

List of 1926 did not alter this rotation. Mr. W. G. Wright in

his “Butterflies of the West Coast” failed to place Stella cor-

rectly, showing white males, etc., together with other specimens

which are not what the name represents. Lack of material also

prevented Dr. J. A. Comstock in his “Butterflies of California”

from identifying Stella and he erroneously puts it (p. 43) as a

“dimorphic form of the female of A. sara ’’ He further con-

fuses its status in the same publication by the placing of the

name as a race in the state list (p. 232), though this placing

happens to be correct. His figs. 13 and 15 (marked Stella) on

PI. 2 probably represent the females of race flora Wright which

is correctly listed as a race of sara Bdv. in the two Barnes lists.

Flora Wright occurs in Oregon and Washington and is a larger

and brighter marked butterfly than reakirtii Edw. Holland in

his new edition of the Butterfly Book balls-up the identifica-

tion of Stella by showing a white male. The usual word “types”

is inserted, regardless of original description data, if it had only

been read.

From the above it can be seen that the group of butterflies

known to Edwards as Stella has been quite an enigma, however

there is no question but that it is a yellowish mountain race and

should be held as such. A new form name is needed for the

yellow examples of race reakirtii Edw., so a comparative de-

scription follows:

Anthocharis SARA REAKIRTII Edw., form flavicoloris Gunder,new

These are race reakirtii Edw. which have the yellow ground

color in both sexes, instead of the usual white background. Its

males are found very rarely (otherwise it would be a sexual

form), while the females are comparatively common. The

amount or spread of the yellow flushing varies in individuals,

the types listed below having complete yellow color. Some-

152

THE PAN-PACIFIC ENTOMOLOGIST

[vOL. IX, NO. 4

times the females show a greenish cast, but this is not uncom-

mon in typical white reakirtii. The red apical patch on the fore

wings, the general black maculation and the dense under side

green design remain the same in flavicoloris as in reakirtii.

It is possible that more yellow forms are found in northern

California around the Bay district, than in southern California.

Race Stella Edw. has a distinct California mountain habitat in

the central Sierras, while race reakirtii Edw. occurs in the hill

districts and costal areas. The yellow of Stella is a delicate

lemon-yellow shade, while the color of flavicoloris is of a deeper

tone, yet not as vivid as that of pima Edw. which is an Ari-

zona insect without geographical connection. The lemon-yellow

of Stella is constant, being of the same shade on both upper and

under surfaces and over the entire ground expanse, while in

flavicoloris the expanse of this yellow shading may not occupy

extreme areas. Yellow examples of species sara are more com-

mon than those of race reakirtii. Also yellow males of sara are

not unknown. Sara was described as dimorphically colored in

the female. I might add that the black maculation in general

of Stella is more delicate than in either sara or reakirtii and in

this respect it approaches julia Edw.

Note Regarding Euschides cressoni Blais.

Immediately after the publication of the description of

Euschides cressoni Blaisd. (Trans. Amer. Ent. Soc., LIX, Sept.

21, 1933, p. 191.), I received word from Prof. H. C. Fall that

he possessed a specimen. A week or so later I received another

specimen collected at La Puerta, California, Oct. 1925, from

Mr. Geo. Field of San Diego, California. Cressoni was de-

scribed from a unique. Three specimens are now known, with-

out further data regarding habitat. It is hoped that other speci-

mens will be secured. — Frank E. Blaisdell, Sr.

COCKERELL, WESTERN BEES

153

NEW OR LITTLE-KNOWN WESTERN BEES

BY T. D. A. COCKERELL

Andrena campbelli Cockerell, sp. n.

Male. Length about or nearly 9 mm., anterior wing 7 mm.; a

species closely allied to herkeleyi V. and C., the males with short

thick flagellum, red beneath except at base, the basal nervure

going conspicuously basad of nervulus, the apical plate of abdo-

men broad and hatchet-like, and the sides of sixth stemite strongly

dentiform. It differs from the description of herkeleyi thus:

clypeus light lemon-yellow except the spots and apical margin;

very small elongate lateral marks next to clypeus on each side;

tergites 2 to 4 with very distinct white hair-bands, that on the

second narrowest; scutellum closely punctured, not strongly

shining; tegulse practically black in front, posteriorly red; stigma

narrow, pale greyish, somewhat reddish, with heavy dark margin;

second cubital cell receiving first recurrent nervure distinctly

beyond middle; second tergite in middle depressed considerably

less than half, but much more than a third. It is also very near

to A. lamelliccuuda CklL, but smaller, with clear white bands on

abdomen and basal nervure going well basad of nervulus. Also

the stigma is quite differently colored. The abdominal structure

is rather suggestive of A. rohertsonii D.T., which is however a

very different insect.

Colorado; Boulder, May 21, 1933 (H. W. Campbell).

There is perhaps some affinity with A. asiatica Friese (Amanu-

sgab, Jariboschi), the male of which is large; face marks very

pale yellow, lateral marks very small; wings dark reddish brown;

basal nervure going far basad of nervulus; second cubital cell

higher than long, receiving recurrent nervure a little below

middle; third cubital cell long; abdomen with white hair-bands

(interrupted on tergites 2 and 3), and red hair at apex. This

account is based on a specimen in the American Museum of

Natural History. Two other species with small lateral face-marks

placed obliquely next to clypeus, are A. erythrocnemis Mora-

witz and A. pallitarsis Perez, but these are small species, the

anterior wing is less than 7 mm. and the basal nervure meets

nervulus in erythrocnemis and falls short of it in pallitarsis.

Compared with A. hridwelli Ckll., A. campbelli is easily known

by the face being not so broad and the clypeus high, quite a

different shape.

THE PAN-PACIFIC ENTOMOLOGIST

[vOL. IX, NO. 4

Andrena physariae Cockerell, sp. n.

Female. Length about 10 mm., anterior wing 7.7 mm.; black,

including mandibles antennae and legs, the tarsi rufescent at apex;

third antennal joint somewhat longer than next two combined,

its length about 430 microns; front vertically striate; facial

fovae narrow, pale reddish, separated from orbit only by a shining

line; clypeus dull and granular at sides, but the broad disc flat-

tened, almost concave, polished, with strong scattered punctures;

process of labrum truncate, with dorsal pit; mesothorax dull in

front but broadly shining on disc, with distinct, not very dense,

punctures; scutellum shining, finely punctured; area of metathorax

triangular, dull; hair of head and thorax red, paler on head (pale

fulvescent on cheeks) but rich fox-red on thorax above, especially

bright on scutellum and postscutellum, but anterior part of

scutellum broadly bare; tegulae black; wings hyaline, faintly yel-

lowish, the broad outer margin conspicuously dusky; stigma well

developed, light ferruginous, without a dark margin; nervures

of basal part of wing dark, but from level of stigma on very

pale reddish; basal nervure falling a little short of nervulus; sec-

ond cubital cell moderately broad, narrowed above, receiving re-

current nervure distinctly before middle; legs with pale reddish

hair, but greyish, not at all brilliant, on inner side of hind tarsi;

middle basitarsi large and very broad, on inner side with a large

black, including mandibles antennae and legs, the tarsi obscurely

rufescent apically; eyes long and narrow, black; facial quadrangle

long and narrow, much longer than wide; clypeus shining and

sparsely punctured, the middle somewhat flattened with no trace

of a ridge; malar space very short but not linear; process of

labrum very broadly truncate, subemarginate, the labrum with

much red hair; second joint of maxillary palpi longest, about 270

microns, last join 175; blade of maxilla very broad; third antennal

joint 335 microns long, fourth 175, fifth 190; facial fovae narrow,

creamy white, close to eye; vertex very narrow, shining on each

side of ocelli; hair of head and thorax very pale dull fulvescent,

more distinctly reddish on scutellum; mesothorax shining on

disc, where it is very weakly and sparsely punctured; scutellum

polished, the disc hardly punctured; area of metathorax entirely

dull, hardly defined; tegulae small, very dark reddish or brownish;

wings hyaline, slightly yellowish, the apical region distinctly

though not deeply infuscated; stigma and nervures (except the

subcostal) clear bright ferruginous; stigma well developed,

pointed apically; basal nervure falling a little short of nervulus;

second cubital cell very narrow, receiving the recurrent nervure

near its end; third cubital cell long; legs with pale reddish hair,

haps no more than a local race or subspecies but the venation

differs. The face is considerably narrower than in A. hradleyi

Viereck and the foveae are much narrower.

brownish beneath, third joint a little longer than next two to-

gether; front finely, longitudinally striate; malar space very

short; cheeks flattened, not produced or angular; mandibles ordi-

nary; lower margin of clypeus black; process of labrum rounded;

hair of head black, a little pale fulvous hair on occiput; thorax

with abundant long pale brownish hair, a sort of very dilute

fulvous, mesothorax dull, the posterior disc shining; scutellum

bands (the type carries a Stylops under the fourth tergite) ; sec-

ond tergite in the middle depressed less than a third; middle of

second tergite dullish with a very fine sculpture of transverse lines.

Colorado; Boulder, May 21, 1933 (W. T, McKean). Re-

lated to A. metea Ckll. from Wyoming but considerably smaller

with hair on thorax not black, the stigma paler and the abdomen

metallic. Also related to A. amplificaia Ckll. from Steamboat

Springs, Colorado, but the clypeus is not so yellow, the hair in

the region of the antennsB is all black, the stigma is paler and

smaller, and the third cubital cell is much more extended beyond

second recurrent nervure, this being due to the position of the

recurrent nervure, not to the length of the cell. The abdomen

is more robust than in A. amplificata and lacks the narrow white

hair-bands at sides of tergites.

Andrena (Trachandrena) veris Cockerell, sp. n.

Female (type). Length 10 mm.; black, including mandibles,

antennae, tegulae and legs; hair of thorax above abundant, bright

ferruginous, of head and other parts of thorax also red but not

so bright; head ordinary; malar space linear but distinct; process

of labrum short, truncate; clypeus densely and coarsely punctured,

without a smooth median line; third antennal joint much longer

than fourth and nearly as long as fourth and fifth together; facial

foveae reddish, rather broad, narrowly separated from orbits, hard

to see on account of long overlapping red hair; a small shining

space at each side of ocelli; mesothorax dull and densely punc-

tured, only the posterior disc somewhat shining, with large coarse

punctures; scutellum coarsely and densely punctured; area of

metathorax large; triangular, with about eight very coarse more

or less wrinkled rugae, and little ones at sides; wings greyish hya-

line, the apical margin darker; stigma large, very dark reddish,

nearly black, varing to dusky red ; nervures fuscous ; basal nervure

meeting nervulus; second cubital cell broad, receiving recurrent

nervure well beyond the middle; legs with reddish hair; hind

tibial scopa pale red; spurs red; abdomen broad convex, shining,

with pale fulvus hair-bands at sides of second tergite, broadly

interrupted in middle on third, and narr owly interrupted or prac-

tically entire on fourth; apical fimbria clear orange-fulvous; sec-

ond tergite in middle depressed about or nearly two-thirds; third

more than half but considerably less than two-thirds.

Male. Length 9-10 mm.; more slender; antennae long, entirely

black; third joint a little shorter than fourth, fourth conspicuously

shorter than fifth; stigma dusky red with dark margin; second

tergite in middle depressed less than half; stipites very broad;

hind coxae with a conspicuous tubercle at apex.

Colorado; Boulder, at flowers of Salix, a pair taken mating

May 6, 1933 (H. W. Campbell). Three other males and a female

were taken by Mr. Campbell on the same date, and Miss Helen

I. Gibbons took a female in Gregory Canyon, Boulder, May 6.

The female looks very like A. cyanophila Ckll. (a late summer

species) but the mesothorax is quite different. It is very near

A. indotata Viereck but my specimen of that (from Saskatche-

wan) has a red stigma and the abdominal depressions are not

so broad. The male is very near A. davisiana V. and C. but

distinguished by the second tergite; it also resembles A. gros-

sularice V. and C. but the tegulae and stigma are quite different

A. tacitida Ckll. is also allied.

Andrena (Opandrena) cressoni transformans Cockerell, sp. n.

Female. Very close to A. cressoni Robertson, agreeing in most

of its characters but differing thus (comparison with a topotype

cressoni received from Robertson) : Face considerably broader (its

width about 2.4 mm.) ; the convex clypeus shining, with very

strong punctures which are largely absent in middle, especially

toward the apex; mesothorax more shining, very distinctly punc-

tured; tegulae larger, clouded with blackish; stigma smaller and

more dusky; wings hardly at all yellowish; nervures fuscous; hind

basitarsus broader, pure black; hair at end of abdomen pale red-

dish, the hair fringing fifth tergite shining silvery.

Colorado; Boulder, June 8, 1933 (Helen P. James). I treat

this as a subspecies, having only one specimen, but I suppose it

to be a segregate which has taken to a different food-plant; a

case similar to that of A. parnassice derived apparently from A.

peckhami. It is at any rate readily recognizable. The type col-

lected only a little pollen consisting of round bright lemon-

yellow grains, but there are also very much smaller elongate

158

THE PAN-PACIFIC ENTOMOLOGIST

[vOL. IX, NO. 4

pale yellow grains, which might come from Draba or some re-

lated plant. The pollen collected by the topotype A. cressoni

resembles the small grains referred to. According to Robert-

son’s list A. cressoni is a frequent visitor to various Cruciferae.

Andrena opaciventris Cockerell

The type (female) is from Claremont, California, and has

the abdomen perfectly opaque. One taken at Riverside, Calif.,

at Salix lasiolepis Benth., Feb. 6 (Timberlake) , has the abdo-

men moderately shining and the hind basitarsi more slender. A

specimen from Boulder, Colorado, April 15 (E. R. Becker) ,

more closely resembles the type but the abdomen is slightly

shining.

Osmia angustipes Cockerell, sp. n.

Male. Length about 8.5 mm., anterior wing 6.3 mm.; yellowish

green with tegulae and legs largely metallic; hair of head, thorax,

and legs long and white, without black hairs intermixed, except

on upper part of mesopleura where there is a certain amount of

dark hair; abdomen with thin long white hair on first tergite,

very short white hair on second, remaining tergites with mainly

black hair but very thin; antennae entirely black, fiagellum quite

simple, not nearly so long as in 0. integrella Ckll.; apical tooth

of mandibles long; clypeus dull and excessively densely punctured

under the rather dull white beard; vertex and mesothorax dull;

scutellum shining between the dense punctures with no smooth

line; area of meta thorax dull; wings rather strongly brownish;

marginal cell with no distinct dark cloud but its apical part and

beyond inf uscated ; basal nervure meeting nervulus ; second cubital

cell receiving first recurrent nervure far from base (the distance

about equal to first intercub itus) and second nearer apex; tarsi

not modified, the apical joint rufescent; abdomen shining olive-

green, the depressed shining margins of tergites quite broad;

sixth tergite with a broad notch, seventh sharply bidentate, the

teeth rather close together; venter simple except that the third

stemite has a V-like emargination, densely fringed with rather

long pale orange hairs; stipites stout, broadly rounded at end.

Colorado; Boulder, April 21, 1833 (H. W. Campbell). In

my table runs to near 0. pseudamala Ckll., but the longer, more

slender hind tibiae readily distinguishes it from that species. It

is easily known from 0. cordata Rob. by the broad shining apical

margins of tergites; from 0. simillima Sm. it is known by the

unmodified flagellum. It is very like 0. coloradensis Cresson

October 1933 cockerell, western bees

but is easily separated by the black hair on apical half of abdo-

men and the less robust hind tibiae. The metallic legs at once

separate it from 0. seneciophila Qcll. which has similar hair

on head and thorax.

Note on the Tarantula Hawk Wasps

Some observations were made, August, 1933, on two species

of tarantula hawk wasps, Pepsis chrysothemis Lucas and Pepsis

cinnaharina Lucas at Twenty-nine Palms, California. Whole

bunches of muscat grapes had been attacked by these wasps and

the juice had been sucked from them so that nothing was left

but the dried skin and seeds. It is known that these insects feed

on ripe figs and peaches that have fallen to the ground or upon

the fruit that has previously been attacked by birds; but no

record has been made, to my knowledge, of their feeding on

sound grapes.

Poison liquid baits as well as poisoned fruits had been used

with little or no success. The baits would soon dry out because

of the dry climate, thus rendering them no longer attractive to

the tarantula hawks. Ripe melons that had been cracked open

were especially attractive food for the wasps, and many were

trapped and killed in this manner; but their breeding ground on

the desert is so extensive that little control was obtained through

this method. — H. L. McKenzie, Citrus Experiment Station, River-

THE PAN-PACIFIC ENTOMOLOGIST [yOL. IX, NO. 4

TWO COLEOPTEROUS FAMILIES NEW TO MEXICO

BY HOWARD E. HINTON

Berkeley y California

While working up some of the material collected by Mr.

R. L. Usinger and the writer in Central Mexico during the sum-

mer of 1933, I found three species of remarkable beetles. One

of these proved to be undescribed, and all three represented fam-

ilies which had not been heretofore recorded from Mexico. The

author is indebted to Dr. E. C. Van Dyke and Mr. E. Gorton

Linsley for their generous assistance in many of the problems

encountered.

Georyssid^ Latr.

This small anomalous family of semi-aquatic beetles contains

some thirty-one species (1932) all in the widely distributed type

genus, Georyssus Latr. Four species have been made known

from the western Hemisphere. G. pusillus (1852) and G. cali-

fornicus (1874) have been described from North America by

Leconte, G. minor (1882) from Guatemala by Sharp, and G.

hum^ralis (1923) from Brazil by Pic.

The species taken by us, G. minor Sharp, was described from

a unique specimen collected in Guatemala. Because the original

description is none too ample, I have seen fit to redescribe the

species from my larger series of fifty-one specimens. All speci-

mens were taken in damp trash piles near the margins of the

streams at Tejupilco, District of Temascaltepec, in June, 1933.

Georyssus minor Sharp

f. 17.

Zaitzev, Col. Cat. 1910, part 17, p. 51.

Small, convex, black, opaque. Head convex, coarsely, irre-

gularly sculptured; eyes convex, moderately finely faceted; first

segment of antennae as wide and four-fifths as long as club, sec-

ond segment not half as wide or long as first, third narrow, half

as long as second, fourth more than three times as long as third,

fifth one-third as long as fourth, sixth slightly longer than fifth;

segments three to six inclusive are very narrow in comparison

with basal segments, club sparsely clothed with very long soft

pubescence, other segments glaberous ; mouth parts testaceous,

maxillary palpi with last segment four times as long as preced-

ing, stout, subsecuriform, accuminate; labial palpi long, last seg-

ment with outer edge straight; inner edge arcuate; mandibles

accuminate, a moderately small tooth on inner edge; labrum

strongly arcuate.

Prothorax unevenly convex, wider than long, sides rounded,

converging toward anterior margin which is slightly emarginate;

anterior and posterior angles rounded; lobed anteriorly, very

strongly, unevenly tuberculate, a median impressed line extend-

ing from anterior to posterior margin; disk finely rugulose,

sparsely, coarsely punctured.

Elytra convex, sides suddenly and strongly converging near

apical end, humeri gibbous, a row of small tubercles near lateral

margins, punctures on disk coarse, as wide or wider than in-

terstices.

Ventral surface roughly irregularly tuberculate, median por-

tion of meso- and metastemum not tuberculate. Legs evenly,

finely, sparsely setose; posterior tibise with two short unequal

spurs.

In the series before me, the sculpturing on the disk is very

variable. A few specimens have the coarse, conspicuous punc-

tuation mentioned by Sharp, a few have the disk only finely

rugulose, and in some examples there is a coarse and scanty

tuberculation on the disk. The extent of the median impression

on the prothorax is also very variable.

Cyathocerid.®: Sharp

This peculiar family has long been known by a single species,

Cyathocerus horni Sharp, recorded from Guatemala and Panama.

In this paper I record the above species from Mexico and make

known a second species in this family.

Cyathocerus horni Sharp

Cyathocerus horni Sharp, Biol. Centr.-Am. 1, 2, 1882, p. 144, t. 4,

f. 18; Supp. 1887, p. 775.

Zaitzev, Col. Cat. 1910, part 17, p. 48.

Sharp and Muir, Trans. Ent. Soc. Lond., 1912, p. 531, figs. 127.

A series of thirty specimens were taken from damp trash

piles left in certain protected corners of a canyon by the alter-

nate rising and receding of the river. These specimens agree

in all respects with the description given of C. horni by Sharp.

However, I wish to call attention to the figure, (Biol. Centr.-

Amer., 1, 2, 1882, t. 4, f. 18) , which is incorrect in one detail.

The vertex of the head, which is similar in sculpturing to the

162

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 4

anterior portion of the prothorax, is drawn as part of the pro-

thorax.

Cyathocerus bufo Hinton, n. sp.

Small, convex, light-brown, opaque. Head strongly, irregu-

larly sculptured, front perpendicular, eyes widely placed at sides

of head near top ; margins over eyes strongly produced and slightly

reflexed forming a shield over the basal part of eyes and antennae;

a short longitudinal impressed line bordered by carinae between

the eyes; eyes coarsely faceted, more than hemispherical, partly

projecting above the pronotum; antennae distinctly shorter than

the width between the eyes; clypeus tran verse, truncate, rugulose;

labrum wider than long, sides slightly rounded and converging

strongly toward apex which is truncate.

Prothorax slightly more than two times as wide as long, sides

converging toward posterior margin, slightly constricted at basal

one-fourth; anterior angles much produced and acute, posterior

angles obtuse; base slightly produced at middle, anterior margin

produced at middle and bi-arcuate on each side of produced por-

tion; very unevenly convex with four large tubercles on disk.

Elytra nearly as broad as long, widest at humeri, suture

barely raised apically, each elytron with three very strongly raised

costze which are slightly sinuate at basal one-flfth and strongly

interrupted twice in basal half, then regularly interrupted and

continuous to apex as a row of smaller tubercles; at middle of

epipleura there is an extremely abrupt sinuation in which the

extremity of the retracted hind femur reposes.

Ventral surface strongly, evenly rugulose; prosternal process

reaching middle of anterior coxae, impressed along median line,

emarginate at end for reception of acute, produced mesosternal

piece; legs slender, short, setose, darker at apex of femora and

base of tibiae; posterior tibiae less than a third longer than tarsi.

Length : 2 mm. ; width, 1.2 mm.

Type (No. 3748, Mus. Calif. Acad. Sci. ), and three para-

types collected by Mr. R. L. Usinger and the writer at Tejupilco,

District of Temascaltepec, altitude 3960 feet, in June 1933. In

most structural details it is very similar to C. horni, but it differs

in its larger size, lighter color, and much more strongly raised

and irregularly interrupted costae. The elytral suture in this

species is only slightly raised apically, whereas in C. horni it is

nearly as strongly raised as are the costae. This species was

also taken in damp frass piles in company with Georyssus minor

and C. horni. Undoubtedly other species in this family will

be found when the American tropics are more thoroughly

collected.

Head and thorax greenish brown, the pronotum with a me-

dian longitudinal black stripe, broadened near posterior margin,

and a round black spot on each side of disk. Elytra chestnut-

brown, lighter near the base and external margin; marked with

five series of bands or spots of golden pubescence; the first basal,

narrow, crossing the scutellum; the second consists of a nearly

round spot on the disk of each elytron just behind the shoulders;

the third consists of a curved line (J-shaped on the left elytron),

commencing just behind the scutellum adjacent to the suture

and recurving slightly before middle of elytra and nearly reaching

external margin; the fourth is a transverse band slightly behind

the middle, which does not extend to the external margin, and

is suddenly broadened at the suture; the fifth consists of a spot

covering the internal apical angle of each elytron, the outside

edge of the spot being rounded. Meso- and metathorax and abdo-

men dark brown, clothed with dull golden pubescence particularly

on the epimera, the metasternum and the lateral and posterior-

ventral surfaces of the abdominal segments; a yellow spot on the

mesepimeron. Legs dull chestnut brown, hind tibiae and tarsi

nearly ferrugineous.

Head with eyes closely approximate in front; a double carina

on frons, the two constituents of which unite towards the base of

the clypeus; a small median carina on occiput; carinae edging: the

frons prominent at margin of eyes. Antennae dull chestnut brown,

clothed with minute pale scales, fine and short, reaching just

beyond base of elytra; scape longer than third segment; fourth

to seventh segments subequal in length, eighth to eleventh sub-

equal. Prothorax subglobular when viewed from above, disk not

swollen; very slightly longer than broad; apex as broad as base;

width at middle subequal to width of elytra at base. Scutellum

short and broad. Elytra long, very slightly narrowed towards

apices ; apices transversely truncated ; external angle of truncature

finely toothed. Legs short, hind femora not quite reaching to

apices of elytra; first segment of middle tarsi nearly as long as

remaining segments united; first segment of hind tarsi only

slightly longer than remaining segments united.

Length 12 to 14 mm., width 2 % to 3% mm.

Holotype, female, (No. 50058, U. S. National Museum, Wash-

ington, D. C.), collected at Kuraru (Koshun), Formosa, on June

7, 1932, by Mr. Y. Yano; allotype, male, in the author’s collec-

tion and one paratype in the collection of E. Gorton Linsley, the

latter two collected at Kisan, Formosa, June 4, 1932, also by Y.

Yano.

This subspecies, which is possibly a distinct species, differs in

several respects from the typical form from continental Asia.

The coloration of the head and thorax and the fasciae of the

elytra are golden instead of grey, and the second elytra fascia

consists of a round spot instead of an oblique line; the average

size is greater, and the legs and antennae are more brightly col-

ored.

Genus Cyrtoclytus Ganglbauer

Cyrtoclytus formosanus Gressitt, n. sp.

Light brown, marked with dark brown and yellow. Body

clothed with long, erect, golden-brown hairs, shorter and sparser

on the pronotum and tarsi, lacking on antennae, thickest on under

side.

Head rugulose, dark brown; thickly clothed with adpressed

golden pubescence on frons, except for mid-line, and narrowly on

posterior margin. Antennae fulvous, thick, not reaching second

quarter of elytra; scape punctate, thick at apex, second segment

globular, a few sparse bristles on first few segments. Thorax

THE PAN-PACIFIC ENTOMOLOGIST

[vOL. IX, NO. 4

globular, not quite as broad as shoulders; dark brown, rugulose,

sparesly clothed with short golden hairs, also with long upright

hairs anteriorly and ventrally; posterior margin yellow, except for

an interruption in middle. Scutellum triangular, pointed, brown,

edged with short pale hairs. Elytra broad at base, slightly swollen

on disk near base, rugulose, apices rounded; base light brown,

marked with three yellow bands of recumbent hairs, the first very

narrow, slightly oblique, a short distance from base, reaching

neither suture nor external margin, edged behind with a broader

dark brown band; second wide, complete, strongly oblique, placed

near the middle of elytra at suture, extending obliquely posteriorly,

becoming broader towards external margin ; the third apical, trans-

verse, wide; anterior to the second yellow stripe is an oblique,

dark-brown stripe about twice the width of the yellow stripe and

parallel with it, slightly broader at the suture where it forms an

angle of about 100 degrees; there is also another dark brown band

immediately behind the central yellow band, about the same width,

broader at the suture; region between this and apical yellow band

reddish brown. Ventral surface of body dark brown, lighter on

abdomen; mesepistemum with an oblique yellow band; first two

abdominal segments banded posteriorly with yellow. Legs tawny

brown, femora and tibiae with long erect brown hairs, tarsi with

shorter, less erect bristles; tarsi broad.

Length 15 mm.; breadth 3.75 mm.

Holotype, female, a unique, in author’s collection, taken by

the author near Numanohira, Arisan, Formosa, at an altitude of

about 7,400 feet, on June 2, 1932.

This species is closely related to Cyrtoclytus caproides Bates

and also to Clytus callizonus Gahan which is probably a Cyrto-

clytus. This may possibly be the species recorded from Formosa

as the latter Indian species, but it is evidently distinct.

Dorsal surface of the body and antennee clothed with very long,

erect black bristles, nearly invisible without a magnifying glass;

ventral surface of body, posterior margins of elytra and legs,

except tarsi and metatibise, clothed with slightly shorter and

sparser white bristles ; metatibiaa with reddish-brown bristles. Head

and prothorax dark shiny green, except for mouthparts which are

with basal fifth, except near suture, red, remainder dark steely

blue with a greenish tinge; a prominent oblique ivory-white raised

line slightly before middle of elytra extending from near external

margin to within one-third of a millimeter of suture; meso- and

metathorax red, with a narrow oblique line on the mesepistemum

and a transverse spot on the posterior lateral surface of metathorax

of silvery white pubescence; abdomen dark steel-blue; legs dark

red, much brighter on clavate portions of femora. Head densely

punctate, except on center of occiput; frons broad, slightly con-

cave between antennal supports; clypeus short and broad. An-

tenna three-fourths as long as body, last four segments shortened

and broadened, scape finely punctate, following three segments

rugulose-punctate; second segment half as long as scape, third,

fourth and fifth segments subequal in length, and each slightly

shorter than scape; sixth and seventh segments slightly shorter,

subequal, remaining segments shorter and subequal. Prothorax

grossly punctate except on sternum; narrowly constricted at base,

broadest at middle and abruptly narrowed posteriorly, anterior

margin broader than posterior, the latter irregular. Scutellum long;

narrow posteriorly. Elytra twice as long as broad, rather con-

stricted and dorsally compressed slightly before the middle,

rounded posteriorly; basal half deeply but sparsely punctate, pos-

terior portion more finely and sparsely punctate. Ventral surface

of body moderately finely and sparsely punctate, least so on abdo-

men. Legs rough, except on clavate portions of femora which

are smooth and shiny; femora exceedingly clavate; fore femora

clavate for two-thirds of their length, middle and hind femora for

slightly less than one-half their length.

Length 6 mm.; breadth (at widest portion of elytra) 1 % mm.,

(at shoulders) 1% mm.

Holotype, a unique, probably a female, in author’s collection,

taken by the author at Koripapono, near Daibu, in the south-

eastern part of Formosa, on April 17, 1932; found running on a

dead branch.

This species is probably closest to Holme chatter jeei Gardner.

It differs, however, in having the prothorax more constricted at

base, the surface more glabrous and punctate, the body clothed

with long erect hairs, and the elytra compressed and constricted

near middle, with the fascia oblique. The latter species is not so

brightly colored.

A European Longicorn New to California (Coleoptera

Cerambycid^)

During the past year the South European longicorn, Leptidea

brevipennis Muls.* has been discovered in several localities in

California. The species belongs in the tribe Psebiini which will

come in our fauna between the Necydalini and Molorchini. The

tribe is characterized by the abbreviated elytra, short mandibles

curved at the base, and the sessile, flattened abdomen broadly

joined to the metathorax. For the benefit of those who may

not have access to the original description, a brief diagnosis is

here appended:

Leptidea brevipennis Muls. Slender, flattened, brownish piceous.

Head nearly flat between the antennee; front short; eyes reniform,

finely granulate; antennae slender, scape moderately stout, reverse

cone-shaped, second segment small, third and fourth segments sub-

equal, each about three times as long as second; fifth segment not

quite as long as third and fourth together, remaining segments

decreasing in length toward apex. Prothorax rufo-testaceous, broad-

er than long, disk sparsely punctured, sides glabrous. Elytra short,

usually attaining the middle of the abdomen, slightly dehiscent,

apices rounded, punctation not coarse, finer and sparser apically.

Legs rufo-testaceous to piceous, short; posterior tibiae curved; tarsi

short, segments cylindrical, third segment not dilated. Length 3-5

mm; breadth .75-1 mm.

The first California specimens of this species were taken

at Santa Barbara, Calif., June 1932, and were reared from

Quercus agrifolia by Mr. A. T. McClay who submitted the speci-

mens to me for determination. Additional examples were cap-

tured at El Monte and Temple, Calif., July 7-10, 1932, by Mr.

Kenneth Sloop. Mr. Sloop’s specimens were taken on the Per-

sian Walnut, Juglans regia. It is possible that L. brevipennis

may have been introduced into California on this latter host. —

NEW DISTRIBUTIONAL AND HOST PLANT RECORDS

OF HETEROPTERA FOR CALIFORNIA. L

BY R. L. USINGER

Oakland, Calif orrda

Euptychodera corrugata (Van D.). The type of this species

was from Ft. Collins, Colorado. A very light colored and heavily

pubescent male and a young nymph are at hand from Marysvale,

Utah, Aug., Wickham, together with a fine series of six females

and two males equally heavily pubescent but quite variable in

color, collected by E. D. Ball in the Baboquivari Mts., Ariz., on

Aug. 17, 1932. In addition there are two females which are very

much darker, smaller and somewhat narrower than the female

type. One of these, together with the Colorado, Utah, and Ari-

zona specimens, is in the Academy Collection. It was collected

by Mr. E. G. Linsley at Uvalde, Texas, in June, 1930. The other

has kindly been presented to the author by Mr. K. D. Sloop who

swept it from alfalfa at Pasadena, Calif., in April, 1932. This is

obviously a very widespread species and will doubtless turn up

more frequently, with careful collecting, throughout the Great

Basin and bordering areas.

Aradus insoletus Van D. A long series beaten by E. G.

Linsley from beneath the loose bark of Salix sp. on the floor of

the Yosemite Valley, Calif., in May and June, 1931.

Gargaphia gentilis Van D. Collected by Mr. Van Duzee on

Carmen Island in the Gulf of California on Solanum hindsiana.

The author found it in abundance on Cercocarpus sp. at South

Fork, Tuolumne Co., Calif., in July, 1928, at an elevation of

approximately 3000 ft.

Reduvius senilis Van D. A specimen has been received from

Sequoia National Park taken by Mr. A. T. McClay on July 18,

1931. The species was originally described from Arizona and

appears not to have been recorded since. The California speci-

men agrees perfectly with the type except that the markings are

a bit more distinct, especially on the hemelytra.

Phytocoris nigrifrons Van D. Taken in numbers by the author

along the trail to the Lookout at the upper end of Fallen Leaf

Lake, Eldorado Co., Calif., in July, 1932, on White Fir, Abies

concoloT.

THE PAN-PACIFIC ENTOMOLOGIST [yoL, IX, NO, 4

Platylygus vanduzeei Usinger. The type of this species was

from the South Rim of the Grand Canyon, Arizona, and para-

types were taken by the author under similar conditions at Mesa

Verde National Park in Southwestern Colorado. Still another

locality on the border of the Great Basin area may now be added.

Mr. E. P. Van Duzee and the author took a series of specimens

on the Sherwin Grade near Bishop, Inyo- Co., Calif., on June 22,

1929. These specimens agree with the type in genital characters

but are a little less distinctly maculated than the Arizona and

Colorado specimens.

Dacerla inflata Uhl. A long series taken by the author on

Lupinus sp. at Mokelumne Hill, Calaveras Co., Calif., on May

18, 1931. This species has heretofore been associated with the

fauna of Pinus jeffreyi in California, but the single catch re-

corded above surpasses by far the total number of specimens

taken on pine during the past few years.

Lopidea eremita Van D. Described from Monserrate Island

in the Gulf of California, the specimens being taken on “palo

tinto” (una de gato ) . The author has received a nice series

of this species from C. C. Searl who took them in San Diego Co.,

Calif., in June of 1928 and 1929. One specimen bears a sup-

plementary label, “Borego Vy. Smoke Tree” and the rest have

labels reading “Yaqui Wl. Ironwood.”

Orthotylus contrastus Van D. Described from a single female

example taken at an elevation of 8000 ft. on Mt. Timpanogos,

Utah. The author has beaten several examples, all females, from

Populus tremuloides at the lower end of Fallen Leaf Lake, Eldo-

rado Co., Calif., elev. 6000 ft., during July, 1929 and 1932.

The specimens have been compared with the type by E. P. Van

Duzee and have been deposited in the collections of Dr. H. H.

Knight, the Calif. Academy of Sciences and the author.

Reuter oscopus falcatus Van D. Beaten in great numbers by

the author from Populus tremuloides at the lower end of Fallen

scarcely as long or as heavy as the median pair on posterior margin

of prothorax; ventral surface of head with the two pairs of bristles

near bases of antennaa not attaining apex of first antennal seg-

ment. Eyes about 0.54 as long as head, hardly 0.7 as wide as their

interval, pilose as usual. Ocelli situated about opposite middle of

eyes. Antennas (cut 1, fig. 2) about 2.25 times as long' as head, of

normal structure; segment 3 usually slightly longer than 6, the

latter about 2.2 times as long as wide and 2.& times as long as 7,

the sense cone on its inner surface not abbreviated, surpassing

apex of segment. Maxillary palpi three-segmented, as usual, the

segments measuring 12, 10, and 18 microns respectively.

Prothorax about 1.6 times as wide as median dorsal length,

with distinct, dark, equally-spaced, anastomosing lines of sculpture

on notum, sides gently rounded, perhaps slightly converging an-

teriorly; bristles at posterior angles rather short, stout, and nearly

straight, the inner pair 64 microns long, the outer pair 50 microns

long; posterior margin with three pairs of bristles, the innermost

pair subequal to midlaterals and somewhat longer and stouter

than postocellars ; other bristles on pronotum hardly equal to post-

174

[VOL. IX, NO. 4

ocellars, excepting one pair near anterior margin and two pairs

at anterior angles. Wings of fore pair (cut 1, fig. 3) with about

22 bristles on costal margin, 4+3 at base of anterior vein and

typically 1 + 1 near apex, and ordinarily about 9 on posterior vein

(though varying from 8 to 11).

Abdomen of normal form; tergite 8 with the comb on posterior

margin broadly interrupted at middle; posterior margin of tergite

9 with bristles of inner pair 100 microns long, outer pair 122 mi-

crons, lateral pair 112 microns ; posterior margin of tergite 10 with

bristles of inner pair 98 microns, outer pair 92 microns; stemites

with the usual three pairs of long bristles on extreme posterior

margin, but without accessory bristles.

Measurements of holotype ( ? ) : Length 1.08 mm. ; head, length

0.114 mm., greatest width (across cheeks) 0.139 mm., width across

eyes 0.132 mm.; eyes, length 0.062 mm., width 0.038 mm., interval

0.056; prothorax, median dorsal length of pronotum 0.118 mm.,

greatest width 0.188 mm.; pterothorax, width 0.232 mm.; fore

The dark color and the broadly interrupted comb on the

posterior margin of tergite 8 ally this new species with magnus,

spinosus, varipes, madronii, and fuscipennis. The pale pronotum,

however, is a thoroughly constant character serving to identify it

readily. There is some variation in the number of bristles in the

distal portion of the anterior vein, three of the specimens pos-

sessing an additional one at the apical two-fifths (on one wing

only), making three bristles in all. The typical number is clearly

two, however, while in all the allied speciesi it is three. Another

structural difference between this and the closely related fusci-

pennis, evident in a series of specimens, is the longer third an-

tennal segment which usually exceeds the sixth in pallidicollis

but which in fuscipennis is invariably shorter than the sixth

Thrips sieversiae Hood, sp. nov.

Cut 2 (figs. 1-4).

Female (macropterous) . Length about 1.4 mm. Color nearly

uniform dark brown, with perhaps the head, prothorax, and tip of

abdomen averaging somewhat darker; legs brown, with fore tibiae,

all tarsi, and both ends of hind tibiae largely yellow; fore wings

yellowish brown, darker at extreme tip; antennae concolorous with

body excepting segment 3 which is pale yellow in pedicel and

shading to yellowish brown at apex; body and wing bristles yellow-

ish brown; ocellar pigmentation orange-red.

Head about 1.31 times as wide as median dorsal length, about

0.81 as long as pronotum, slightly broadest across eyes, the trans-

verse anastomosing lines dark and distinct; cheeks somewhat flat-

tened; vertex fiattened, not forming an overhanging angulation

but sloping nearly evenly from ocelli to frontal costa, this last

deeply and acutely notched; interocellar and postocellar bristles

short, subequal, somewhat longer than postoculars but scarcely as

long or as heavy as the median pair on posterior margin of pro-

thorax; ventral surface of head with the two pairs of long bristles

near base of antennae, the inner pair much the longer and reach-

ing beyond base of second antennal segment. Eyes about 0.57 as

long as head and about 0.7 as wide as their interval, prominent

because of their size but not distinctly protruding, pilose as usual.

Ocelli situated slightly in advance of middle of eyes. Antennae

(cut 2, fig. 2) long, about 2.57 times as long as head, of normal

structure, segment 3 slightly shorter than 6, the latter fully 2.6

times as long as wide and 2.4 times as long as 7, the sense cone

on its inner surface short, not attaining apex of segment.

Prothorax about 1.46 times as wide as median dorsal length,

with distinct, equally-spaced, anastomosing lines of sculpture on

notum, sides gently rounded and distinctly converging anteriorly;

bristles at posterior angles rather long and strong, only slightly

curved, the inner pair about 84 microns long, the outer pair about

76 microns long; posterior margin with three pairs of bristles, the

of inner pair 122 microns, outer pair 118 microns; stemites with

the usual three pairs of long bristles on extreme posterior margin

but without accessory bristles.

Described from seven females and two males taken at Grant,

Colorado, July 19, 1916, by L. 0, Jackson, on Sieversia ciliata.

In Priesner’s key to the European! species, if the abdomen be

considered “ungewohnlich breit”, this runs to rohustus and dila-

tatus; but in both of these segment 3 of the antenna is much

narrowed apically. If, on the other hand, the abdomen be con-

sidered of normal breadth, this species runs to paluster and

menyanthidis ; but from these it differs in the short sense cone

on segment 6 of the antenna.

Among the North American species, it takes a natural posi-

tion near fuscipennis, agreeing with it and its relatives in having

three pairs of small bristles on the posterior margin of the pro-

notum between the two large pairs at the posterior angles; in

having the comb on the posterior margin of abdominal tergite

8 broadly interrupted at middle; and in having the fore wing

provided in the distal half of the median vein with three instead

of two bristles. It comes closest, perhaps, to magnus, a Cali-

fornia species in which the sense cone on the inner surface of the

sixth antennal segment is likewise short and scarcely attains the

tip of the segment. From magnus, however, it differs in having

segment 6 of the antenna slightly longer instead of distinctly

shorter than 3 ; in having segment 5 twice as long as 7 ; in having

the antennae, particularly segment 3, decidedly paler; and in

having the fore wings pale brown and decidedly lighter than

the body.

Thrips sambucifloris Hood, sp. nov.

(Cut 3, figs. 1-4).

Female (macropterous ) . Length about 1.3 mm. Color dark

blackish brown, with red or orange-red pigmentation in ptero-

thorax; legs blackish brown, with all tarsi, both ends of mid and

hind tibiae, and most of fore tibiae pale grayish yellow ; fore wings

pale gray (nearly white) in basal fourth and dark brownish gray

beyond, the veins darker; antennae dark blackish brown, 2 darker

than 1, 3 decidedly the lightest in entire antenna, grayish or brown-

ish yellow and clouded with blackish brown in distal half, 4-7 dark

blackish brown, 4 andi 5 narrowly paler just beyond pedicel; body

and wing bristles dark brown; ocellar pigmentation red.

Head about 1.27 times as wide as median dorsal length, about

0.92 as long as pronotum, broadest slightly behind eyes, the trans-

verse anastomosing lines dark and distinct; cheeks rounded,

slightly converging posteriorly; vertex flattened, sloping evenly

from ocelli to a slight angulation above antennal base, the frontal

costa acutely but roundly notched; interocellar and postocellar

bristles sub-equal, distinctly longer than postoculars but scarcely

as long or as heavy as the median pair on posterior margin of

prothorax; ventral surface of head with the two pairs of bristles

near bases of antennae, the inner pair much longer and reach-

ing beyond base of second segment. Eyes about 0.55 as long as

head and about 0.8 as wide as their interval, prominent because

of their size but not distinctly protruding, pilose as usual. Ocelli

situated slightly in advance of middle of eyes. Antennae (cut 3,

fig. 2) about 2.37 times as long as head, of normal structure, seg-

ment 3 longer than 6, the latter about 2.36 times as long as wide

and 2.6 times as long as 7, the sense cone on its inner surface

surpassing apex of segment.

Described from two females and fifteen males taken by the

writer near Korbel, California, July 28, 1927, in flowers of

Sambucus racemosa L. [Hood No. 710]. Males were very abun-

dant, but only two females were seen.

This is another species of the fuscipennis group. It is readily

distinguishable from pallidicollis by the dark coloration and the

greater number of wing bristles; from sieversice and magnus by

the longer sense cone on the inner surface of the sixth antennal

segment; from spinosus by the shorter interocellar bristles; and

from fuscipennis and varipes by the lack of a tympanum on

abdominal sternite 7 in the male, as well as by numerous details

of body structure and color.

Attraction of Beetles to Tar

For the past two years I have noticed the attraction of cer-

tain beetles to fresh tar. The observations were made at Ben

Lomond, Santa Cruz County, California, in May, June, and July

of 1932 and 1933. The species most abundant was the Lucanid,

Platycerus agassizi Lee, which assembled in large numbers near

the fresh tar on dirt roads; all of the specimens but three were

males and were caught either in the tar or flying at a height of

six or eight inches above the tar. Diligent search in other near-

by roads which had not been tarred availed nothing in the way

of this Lucanid; I have now taken a very large series of this

species while in previous years, before collecting in the tar, I

obtained only two or three a season. The only other beetle

found there in numbers was the Ostomid, Temnochila virescens

(Fab.). — Lawrence W. Saylor.

VAN DYKE— PLEOCOMA

183

A NEW SPECIES OF PLEOCOMA

Coleoptera-Scarabaeidae

BY EDWIN C. VAN DYKE

University of California, Berkeley, California

Pleocoma shastensis Van Dyke, new species

Broadly oval, robust, black, fimbriated and clothed beneath

with long, very dark brown hair. Head coarsely punctured above;

eyes very large and prominent; clypeus broadly emarginate at

apex, the angles equilateral and obliquely reflexed; lobes of the

genae prominent, the anterior margins at right angles to head,

the apices rather evenly rounded and the dorsum deeply tri-

angularly sulcate, smooth and shining; frontal horn prominent,

broad at base, acute at apex, and perpendicular; antennae with

the first seg’ment long and robust; third slightly more than one-

half the length of the first, the outer four segments with long

lobes, about equal in length, which when approximated form the

club, the seventh segment with an appendix not quite one-half

the length of that of the eighth. Prothorax twice as wide as

long, apex broadly emarginate, base arcuate, sides broadly rounded

in front, more shallowly arcuate posteriorly, in the type sub-

angulate behind middle, with rounded hind angles; disk mod-

erately convex and rather finely, more or less densely, punctured,

the basal area more finely punctured. Scutellum rather coarsely,

densely punctured and clothed with the long dark brown hair on

both disk and along margins. Elytra a little broader behind the

middle; dorsum slightly depressed, distinctly impressed behind

scutellum; sutural striae faint in front but moderately well im-

pressed behind, the two inner pairs of geminate striae fairly

distinct except posteriorly and more or less punctate, the others

vague; general surface obscurely rugose and with a moderate num-

ber of fine, scattered punctures but appearing at first glance as

rather smooth and shining. Body beneath quite densely clothed

with long very dark brown hairs. Legs very robust, the middle

and hind tibias about one-third larger than they are in rickseckeri

and behrensi; tarsi also' robust, the middle and hind tarsi shorter

by at least 1 mm. than the tibiae. Length 25 mm., breadth 13 mm.

Holotype male (No. 3779, Mus. Calif. Acad. Sci.) and seven

paratype males collected by Dr. K. A. Salman near Pondosa,

Siskiyou County, California (T 38 N, R 2 E) . They were flying

during a snowstorm over cut-over lands of the Shasta National

Forest (S.E. of Mt. Shasta), October 22, 1932.

This interesting species is perhaps most closely related to

rickseckeri Horn and puncticollis Rivers, agreeing with them as

184

THE PAN-PACIFIC ENTOMOLOGIST

[vOL. IX, NO. 4

regards the very dark color, four-segmented antennal club and

rather short third antennal segment. It differs by having the

hair a dark brown, not black, the scutellum rather coarsely punc-

tured and clothed with hair, not almost smooth and without hair,

and the middle and hind tarsi distinctly shorter than the tibiae,

not of equal length as in the others. It is slightly larger than

rickseckeri, smoother and more shining, with the prothorax pro-

portionally broader and the hind angles more broadly rounded,

the clypeal angles in front more widely separated and less re-

flexed, and the frontal horn more or less equilateral and per-

pendicular, not transverse, bifid at apex and tilted backwards

as is the case in rickseckeri. Pleocoma puncticoUis Rivers is

much larger, entirely black, with elytra much smoother, the pro-

thorax of about the same general proportions yet broader pos-

teriorly and with hind angles distinct and the disk very coarsely

and closely punctured, the clypeal angles acute, much longer

and more vertical, and the frontal horn similar to that of

rickseckeri.

TWO OLD AND TWO NEW PLEOCOMAS

BY E. R. LEACH

Piedmont, California

In the forty-five years that have elapsed since Dr. George H.

Horn in the Transactions of the American Entomological Society,

January 1888, described Pleocoma ulkei from a single male and

Pleocoma conjujigens from a series of three, no other speci-

mens, so far as I am aware, have been known until the past two

months when, by a strange coincidence, both were rediscovered

almost simultaneously, one in the field and the other in the

museum.

On October 3Ist last in Nevada County, California, I took

a short series of males that agreed with Dr. Horn’s description

of ulkei. A specimen was carefully compared with the type

by Mr. Chas. Liebeck, who writes “I would not hesitate to call

these two specimens one and the same species”. The type is

labeled “Utah” but its correctness has always been doubted by

those familiar with the genus. And now that this species has

been collected in California the doubt is more than justified.

October, 1933

LEACH— PLEOCOMA

185

as, to one knowing anything of the life history of the Pleocomas

with their wingless and ponderous females “rooted to the soil”

as it were, it is impossible to conceive of the same species

occurring in both California and Utah. It is more logical to

believe the locality was erroneously recorded on the type label,

especially as some of the older collectors were notoriously care-

less in this respect.

The original description of ulkei is excellent and enables

one to recognize the species at a glance. Dr. Horn was in doubt

as to whether the “paler elytra are due to immaturity or repre-

sent the full color.” It can now be stated that the “pale cast-

aneous” color of the elytra is the color of the fully matured

insect. The thorax is piceous as stated by Horn, making the

species distinctly bololorous.

While studying the material in the collection of the Cali-

fornia Academy of Sciences I discovered four male specimens

collected by Dr. F. E. Blaisdell, Sr., at Mokelumne Hill, Cala-

veras County, California, that appeared to be conjungens. Mr.

Liebeck again kindly compared a specimen with the type and

says “it is sufficiently similar in its main characteristics to

safely call it conjungens” Dr. Horn’s three specimens were said

to have been taken in the same flight at Santa Cruz, California.

Mokulumne Hill is 120 miles from Santa Cruz across a hot, dry

plain where no Pleocomas have ever been collected and where

it is unlikely they could exist. This is another distribution that

is difficult to understand unless the original locality is again

in error. A careful study of a series from Santa Cruz will be

necessary to settle the question definitely.

Pleocoma conjungens resembles fimbriata except in the an-

tennal structure as mentioned by Dr. Horn. Another marked

difference is in the shape of the prothorax. In conjungens it is

widest at the base with prominent basal angles, in this respect

approaching P. tularensis described herein.

Dr. Horn’s paper contains still another indication of care-

lessness in recording localities. He reported Pleocoma staff

from California. As a matter of fact is occurs in Oregon 200

miles from the California border.

186

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. IX, NO. 4

Pleocoma oregonensis Leach, n. sp.

Form robust, rounded, bicolorous and shining above, clothed

underneath with long dense golden brown hair; densely fimbriate

on prothorax, lightly on elytra.

Head piceous, coarsely and densely punctured except on pre-

ocular lobes which are smooth, shining, wide and broadly rounded

at apex; clypeus deeply emarginate, angles acute; cephalic horn

moderate in size, round, and acute at apex. First segment of

antennae heavy and sub-conical; second transverse; third almost

three times as long as the second and three-fourths as long as

the first; sixth with a slight lobe; seventh with a lamina almost

one-half as long as those on the eighth, ninth, tenth and eleventh

segments which form the club.

Prothorax dark brown above, broadly rounded at the sides

and basal angles, widest slightly behind the middle; disk bearing

a slight transverse elevation before which is a large shallow de-

pression one-half the width of the pronotum, forming a declivity

in front; behind is a narrow, median, depressed, impunctate sur-

face on both sides of which are smaller depressions; the surface,

except as noted, finely and closely punctured, becoming coarser

and confluent at the sides and front.

Scutellum clothed with long golden brown hair especially dense

at the sides and hidden also by long thick hair of the same color

from the base of the prothorax.

El3rtra light red-brown; at humeri very slightly wider than

the pro thorax, widest at the middle; sutural strise deeply im-

pressed their entire length, not widened at apex, the four pair

of geminate strise distinctly but not deeply impressed, fading out

at the apex.

Legs stout, posterior tarsi much shorter than the tibise (4.8

mm. to 6.2 mm.).

Length 23 mm., width 13 mm.

Described from a single male taken at Wasco, Oregon (1908) ,

which has been in my collection many years. (Type in collec-

tion of the author).

In size, shape and sculpture this species resembles staff but

has a more prominent prothoracic ridge and is more retuse in

front. In color and configuration of the prothorax it is close

to ulkei. From both these species oregonensis is at once dis-

tinguished by its four-leaf antennal club.

Pleocoma tularensis Leach, n. sp.

Form robust, oval, black, shining above, fimbriate at sides of

prothorax and elytra, clothed underneath with long dark brown

hair.

October, 1933

LEACH— PLEOCOMA

187

Head piceous, moderately punctured; elypeus deeply emargi-

nate, angles slightly divergent; cephalic horn, long, flattened and

emarginate at tip. Third segment of antennae almost three times

as long as second and three-fourths as long as the first; sixth

segment with a lobe shorter than its length; seventh with a lobe

slightly longer than its length; eighth, ninth, tenth and eleventh

segments with long lamellae of increasing length, the last being

slightly the longest and equal in length to the first nine segments.

(3.6 mm. in type.)

Prothorax twice as wide as long (13 x 6.3 in type), angled

at the sides and convergent in front, widest at base; basal angles

prominent; very slightly depressed before and behind the disk;

surface finely punctured as in fimbriata.

Scutellum finely and sparingly punctured, less so at apex.

Elytra at humeri as wide as base of prothorax, widest slightly

behind the middle, the sutural striae becoming more deeply im-

pressed toward the apex where the interval is slightly thickened.

The four pairs of geminate striae very feebly developed.

Legs moderately short, the hind tarsi longer than the tibiae.

(7.6 mm. to 7 mm.)

Length of type 26.5 mm., width 14.6 mm.

Described from a long series of males taken by Mr. E. Gorton

Linsley in Sequoia National Park, Tulare County, California,

November, 1932. I also have specimens collected by Mr. F. T.

Scott at the same place, and have examined others in the Acad-

emy collection, taken at Badger in Tulare County. Largest speci-

men 28.5 mm. long by 17 mm. wide. Smallest specimen 23.5

mm. long by 13.6 mm. wide.

Type No. 3780, Mus. Calif. Acad. Sci. from Sequoia National

Park.

Pleocoma tularensis is near australis Fall but is readily

recognized by its broader form and differently shaped prothorax,

which in the former is much wider at the base and more acute

in front and much more finely punctured. From fimbriata it is

separated by the longer third segment of the antennae, the larger

antennal club, the more prominent basal angles of the pro-

thorax, its darker color and smoother and more polished elytra.

For material and suggestions during this study I am deeply

indebted to Dr. E. C. Van Dyke, Dr. F. E. Blaisdell, Sr., and

Mr. E. Gorton Linsley.

Collecting Notes

On March 15 of this year, I collected at Ben Lomond,

Santa Cruz County, California, under debris in a chicken yard,

a specimen of the extremely rare Aphodius cadaverinus (Mann,).

To the best of my knowledge this is the only specimen known in

American collections besides that of Dr. Van Dyke in the col-

lection of the California Academy of Sciences, collected near

Clear Lake, Lake County, California.*

I also took at Ben Lomond three specimens of Aphodius

opacus Lee. They were collected March 20, at about noon, and

were flying along a narrow dirt road within the margin of the

Redwood forest. These are the first I have encountered in this

region in three years collecting, I do not know of any records

of this species being collected so near the coast in Central Cali-

fornia.

I have a specimen of A. distinctus (Mull.) from Dunsmuir,

California, collected by Mr, H, E. Hinton, and determined by

Mr, W. J. Brown, I do not know that this species has ever been

recorded from California before; it is probable that this Euro-

pean species is constantly spreading westward and will in time

become common on the Pacific Coast.

At Ben Lomond I have also collected A. spar sus Lee., A.

neatomoe Fall, A. tuberosus Barrett and A. davisi Fall, all in the

nests of the Wood-rat, Neotoma. I usually take these species in

late January or February. My specimens of tuberosus are usually

almost entirely piceous, but Mr. Barrett has very kindly com-

pared them with his types and they agree perfectly except for

color. Of the above, sparsus is the only one taken commonly;

neatomoe is much rarer, and davisi and tuberosus are quite rare.
