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. ^ Noctuidro of Authors. 2 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.

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.

Apatelin^ Speocropia fernae Benjamin, n. sp. Head, thorax, and fore wing dull rufous brown mixed with black; basal half line geminate, defined by black, excurved; trans- verse posterior line geminate, defined by faint black edging, in gen- 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- form, extending to about vein 3, thence inwardly oblique to inner margin; reniform poorly defined, faintly outlined by black, pale. 4 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- ^ Agrotisia Hampson, subhyalina Hampson sole species and designated type; 1908, Cat.

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. Acontiin^^ Phcenicophanta modestula Dyar 1924, Dyar, Ins. Inscit. Menstr., XII, 16, Phcenicophanta.

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.^ ® New Gen. and Sp. Noct. Br. Mus. ® Tathorhynchus Hampa., type Scapula vinctalis Wlk., 1894, Hamps.. Fauna Brit.

JANUARY, 1933] HATCH— MISCODERA 7 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. 8 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. JANUARY, 1933] SALMAN— A NEW PEPSIS 9 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 10 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. JANUARY, 1933] CHAMBERLIN— MYRIOPODA 11 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. CHILOPODA Oryid^ 1. Notiphilides maximiliani (Humbert and Saussure) Notiphilus maximiliani Humbert and Saussure, Rev. et Mag.

Otostigmus scabricaudus (Humbert and Saussure) Branchiostoma scabricauda Humbert & Saussure, Rev. et Mag. ZooL 1870, vol. 22, p. 203. Locality: Costa Rica: San Isidro Coronado. One specimen taken May 4, 1929. This specimen lacks the anal legs and most of the anal segment, but seems, as judged from other parts, to be the species which was previously recorded from San Mateo and Cocos, Costa Rica. It also occurs in Brazil and Columbia. SCOLOPENDRIDJE 6. SCOLOPENDRA VIRIDIS Say Proc. Acad. Nat. Sci. Phil,, 1821, p. 110. Locality: Costa Rica: Salinas; San Jose. One specimen from each place taken by M. Valerio in 1929. This species is com- mon from the southeastern United States to Central America. It was previously recorded in Costa Rica from Juan Vihas (P. P. Calvert) and Cache. 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.

Gonopods of the female with basal joint excavated within as usual ; basal spines 3 + 3 ; claw strictly entire. 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. Prosternal teeth 6 + 6. The ectal spine dentiform and much 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. Posterior angles of the ninth, eleventh and thirteenth dorsal plates produced strongly, those of the seventh also a little angularly produced. Surface of tergites strongly rugose. Coxal pores circular, in a single series. Length 22 mm. Locality: El Gallito. One female in poor condition taken by 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. DIPLOPODA Platyrrhacid.® 9.

Gonopods of the male as represented on page 15, fig. 3. Length about 50 mm.; width 9 mm. Locality: Parismina. One male taken Feb. 26, 1928. This species is readily distinguishable from other species in the form of its gonopods; e.g., by the acutely prolonged apical portion of both blades of the telopodite. 23. Chondrodesmus euliotus Chamberlin, new species Dorsum light chestnut, the keels, excepting at base, yellow and an obscure and partly discontinuous median longitudinal line also yellowish; sides light chestnut, the venter pale. In size, coloration and general appearance suggesting C. singu- laris Chamberlin but differing in the characteristics of the keels. The fifth keel does not have its anterior corner shouldered out beyond the level of the porigerous prominence, and the posterior keels on caudal margin have a dentiform projection which is lack- ing in singularis.

Antennae with the usual four terminal sensory cones. Collum narrowly margined about antero- ventral border; a hori- zontal stria at level of each eye extending from anterior margin nearly to middle of plate. Segments weakly constricted, the sulcus deeply impressed along anterior border of the depression and in front of level of pore, to embrace which it curves back abruptly. Each scobina consisting of a deeply impressed lunate pit at the margin of the tergite followed by a posteriorly pointed area of fine striae; each pair of scobinae separated by a distance of from once and a half to twice the length of a scobina; present caudad to about the thirty-fourth segment. Anal tergite rounded behind; exceeded by the valves. Valves slightly compressed but not margined. Anal scale caudally rounded.

Collum with a fine margining sulcus about the anterior corner ; surface smooth and shining, but with some coriarious impressions, especially on each side at and below the level of the eye. Second tergite extending much below level of the collum, the lower end triangular, the sulcus fine and obscure dorsally. Sulci on the fol- lowing segments complete, narrowly excurved opposite the pore. Tergite smooth and shining, striate only below. Scobina obscure on eighth segment but distinctly developed from the ninth segment caudad; anterior impression deep, trans- versely elliptic, widely separated; the posterior striate area pointed behind. Anal tergite bluntly rounded behind; much exceeded by the valves; two transverse shallow furrows between middle and caudal end. Anal sternite very wide, the caudal margin convex, differing in this conspicuously from R. simulans, a closely related species. (Page 15, fig. 9.)

It is hoped that the convenience for bibliographical purposes of this change in dating will in a measure recompense our subscribers for the long interval between the last issues. Those subscribers who have paid for the calendar year 1932 will be credited with six months’ subscription on volume nine for 1933.

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 of evening primrose (Onagraceae)\ The species is easily known 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 Ckll. In S. euxantha Ckll. the labial palpi have the first joint enormously elongated, longer than the head, while the other three are very minute. S. euxantha (from Claremont, California) must ^ Mr. Timber lake informs me that he also has taken S. puettas.

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 ^ For reasons given in Proc. Calif. Acad. Sci., XII (1923), p. 101, I do not think the name Nomadopsis Ashmead is available. JANUARY, 1933] COCKERELL— BOREGO BEES 27 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; 28 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 JANUARY, 1933] COCKERELL— NOTE ON ANDRENA 29 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.

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. ^ Pan-Pac.

JANUARY, 1933] VAN DYKE— DYSLOBUS 31 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 t 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. SYNOPTIC TABLE 1.

It has a preference for the foliage of the true firs. Normally the pronotum is quite smooth though finely punctured and minutely granulate when abraded. In a specimen from the southern part of its range, Sequoia National Park, the pronotum is markedly granular tuberculate. Dyslobus lecontei Casey This species is large like the preceding but generally more elongate and proportionally narrower. It is a species of the more humid area of the Northwest. Dyslobus simplex Van Dyke, new species Rather large, moderately robust, black, densely clothed with golden brown or cupreous scales and very short, much inclined setae on the rostrum and elytral declivity. Head rather finely, closely punctured, the punctures generally concealed by the scales ; rostrum twice as long as broad, separated from front by a shallow transverse impression, broadly shallowly sulcate towards apex and with fine median carina; eyes much fiattened, hardly projecting beyond sides of head, antennae with scape reaching hind margin of eyes, funicle with first and second segments elongate, third to sixth much shorter and gradually diminishing in length though always longer than broad, seventh somewhat longer and broader than 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.

The type locality is Homestead Inn, 38 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 JANUARY, 1933] VAN DYKE— DYSLOBUS 39 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. 40 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

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 JANUARY, 1933] VAN DYKE— DYSLOBUS 41 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- 42 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

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 JANUARY, 1933] VAN DYKE— DYSLO BUS 43 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, 44 THE PAN-PACIFIC ENTOMOLOGIST [yOL.

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. JANUARY, 1933] VAN DYKE— DYSLOBUS 45 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.

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.

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. 48 THE PAN-PACIFIC ENTOMOLOGIST [VOL. IX, NO. 1 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.

IX, No. 2 April, 1933 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. 2 Determined by Mr. R. A.

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. 52 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.

APRIL, 1933] BENJAMIN— NOTES ON PHAL^RRID^ 53 NOTES ON PHAL^NID^* FROM ARCTIC AMERICA, SUPPLEMENTED WITH MATERIAL FROM HIGH ALTITUDES BY FOSTER H. BENJAMIN Bureau of Entomology, United States Department of Agriculture 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. Archanarta quieta Hbn. 1805?, Hiibner, Schmett. Europ., Noct., f. 485, Noctua. 1929, Barnes & Benjamin, Bull. B’klyn Ent.

Dr. McDunnough appears correct in his contention that Ar- chanarta is related to Anomogyna.^ This relationship includes *Noctuidse of Authors. ^ 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. 54 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^ 55 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.

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.

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. This “species” was described from Repulse Bay. Mr. Tams has been unable to match the type which probably represents a local race of richardsoni from the vicinity of the Melville Peninsula.

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.

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. Anarta magna B & Benj. 1924, Barnes and Benjamin, Contrib. Nat. Hist. Lep. N. Am., 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 60 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

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.

IX, NO, 2 probably from near New York City. From a male Mr. Johnson 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 tarsi as 29-11-9-6-10, of posterior as 20-18-10-10-4. Length of front tibiae in the female as 51, middle 72 and posterior as 82; joints of front tarsi of female as 25-8-8-9-6; of middle pair as 38-16-13-10-10; and of posterior as 23-21-16-12-12.

APRIL, 1933] VAN DUZEE— FIVE DIPTERA 67 Campsicnemus nigripes Van Duzee Entomological News, Vol. XXVIII, p. 126, 1917, Nigripes was described from a single male which was taken at Sacramento, California. In 1926 I took a series of this species at Boulder, Colorado. The drawings given here are made from these specimens; Fig. 4 shows the middle tibiae and tarsi nor- mal, the tibiae and tarsi being wholly black. Fig. 2 shows the middle tibiae as it often appears, probably because it is twisted, it being very much compressed and thin; the antennae are pointed at tip (Fig. 3) and wholly black; length of middle tibiae as 70; joints of fore tarsi as 23-9-6-5-5; of middle pair as 22-8-7-5-8; and of posterior pair as 17-17-11-7-8. 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.) — H. H. Keifer, California Department of Agriculture, Sacra- mento, California. 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 68 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.

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 the length of first antennal segment.

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. Van Duzee. APRIL, 1933] COTTLE— ARGYNNIS BEHRENSI 73 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. 74 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. APRIL, 1933] INGHAM— NEW BUTTERFLIES 75 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. 76 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. Holotype $ ; expanse 27 mm., April 2, 1932; Middle Ranch, Santa Catalina Island, California. Allotype $ ; expanse 28 mm., same date and locality. These types deposited in the Type Col- lection of the California Academy of Sciences at San Francisco. One pair of paratypes, matching types, of same date and locality placed through Mr. Foster Benjamin in the United States Na- tional Collection, Washington, D. C. One pair of paratypes, matching types, of same date and locality deposited through Dr. J. McDunnough in the National Collection at Ottawa, Canada. One pair of paratypes, matching types, of samel date and locality in the author’s collection. I take pleasure in naming this An- thocharis after Mr. Jeane D. Gunder who so kindly loaned me material from his extensive collection for comparisons with my type lot. APRIL, 1933] MILLS AND ROLFS— COLLEMBOLA 77 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. Order Collembola Lubbock Subfamily PoDURiN^ Borner Podura aquatica (L.) Yakima, February 23, April 19, Septem- ber 6.

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. Neanura gigantea (Tull.)

IX, NO. 2 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.

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 86 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 * Pan-Pac. Ent., Vol. V, No. 2, Oct,, 1928, p. 9B. ® JI. N. Y. Ent. Soc., Vol. XXVI, June. 1918. APRIL, 1933] HOPPING— A NEW BUPRESTID 87 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- 88 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 89 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. APRIL, 1933] HILTON— NEW WHIP-SCORPION 91 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. 92 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.

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.

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. 96 THE PAN-PACIFIC ENTOMOLOGIST [VOL. IX, NO, 2 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. Holotype, male.

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 98 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 99 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.

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.

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- 102 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

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.

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.

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 July, 1933] 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- ^ Ann. Soc. Ent.

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 July, 1933] SCHAEFFER— CHRYSOMELID^ 109 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. 110 THE PAN-PACIFIC ENTOMOLOGIST [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.

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). Gehringia olympica. 1. Entire insect. 2. Inner wing. 3. Pos- terior part of metasternum, hind coxae, and first three ventral seg- ments (semi-diagrammatic). 4.

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.

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. ’ Notes and descriptions of New Species of Scarabseidse from western North America, by Edwin C.

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.

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- son (44th Ann, Rep, Ent. Soc, Ont, for 1913, Ent.

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.

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.

July, 1933] 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.

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.

July, 1933] CAUDELL— A NEW SIALID 125 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: Neohermes infuscatus Caudell, new species Venation and other diagnostic structural characters as given for the genus Neohermes in Banks’ key to the genera of Coryda- linae.* The general color is deep brownish black' to dead black, the * Proc. Ent. Soc. Wash., vol. X, pp. 28-29 (1908). 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 126 THE PAN-PACIFIC ENTOMOLOGIST [VOL. IX, NO. 3 canyons near Vacaville, Solano County, California, on June 1, 1932. Holotype, female, and allotype, male, in United States Na- tional Museum, Catalog No. 44900; two paratypes, one in Mu- seum of Comparative Zoology and one returned to the University of California. There is scarcely any noticeable variation in these specimens except that the allotype and one paratype are more densely and uniformly black in the coloration of the wings. 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.

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. The Moths of South Africa Volume I of this important work has recently been published by the University of Pretoria. It is by A. J. T. Janse and covers the Geometridee and the small family Sematuridae (one species). It forms a neatly printed volume of 376 pages and 15 plates, the publication of which was greatly helped by a grant of £400 from the Carnegie Corporation. How much such a grant would help toward the completion of Professor Forbes’ work on the moths of the eastern United States! — E. P. Van Duzee. JULY, 1933] 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. July, 1933] 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. Holotype, male, (No. 3741, Calif. Acad. Sciences), allotype, female, (No. 3742, Mus. Calif. Acad. Sciences) and several para- types, collected at Santa Ilena, Chimaltenango Province, Guate- mala, elevation 9800 ft., on July 31, 1926, by Mr. Joseph R. Slevin. Additional paratypes, Chicavac, Chimaltenango Province Guatemala, elevation 8600 ft., August 1926, also collected by Mr. Slevin. One pair of paratypes is deposited in the collection of the writer, the remainder are in the collection of the Cali- fornia Academy of Sciences in San Francisco. The writer is 132 THE PAN-PACIFIC ENTOMOLOGIST [VOL. IX, NO. 3 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: Cosmotoma sertifer Serv. Pogonochei'us sertifer Serv. Ann. Soc. Ent. Fr., IV, p. 59, 1835. Cosmotoma viHdana Lac. Gen. Col.

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.

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- wings slightly smoky. Holotype, male (labeled) Pasadena, Calif. Taken by the author from an Arctostaphylos on the lower portion of the trail July, 1933] BALL— NEW ACHILID^ 135 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. July, 1933] 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 Color, pale, cinnamon, the pronotum and head paler. Longi- 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. ^ Pan-Pacific Ent.

July, 1933] 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.

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^.

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. 144 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

BENJAMIN Bureau of Entomology, United States Department of Agriculture 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.

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.. October, 1933 BENJAMIN— PHAL^NIDvE 147 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: Anomogyna perquiritata clarkei Benjamin, new subspecies Xarctica Auct. (nec Zett.). 1905, Smith, Jour. N. Y.

Size and general habitus of partita, with the same blackish powdery appearance, but differing by the fore wing possessing paler basal, terminal, and subterminal areas, causing the median portion to appear disconcolorously blackish; in addition the sub- terminal sagittate black dashes are larger and more contrasting; the basal black dash is defined; and a strongly marked claviform is present.

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.

(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. Holotype male, expanse 37 mm..

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. October, 1933 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. 154 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

The pollen collected is yellowish white, the grains spherical, probably belonging to Campanula. Nearest to A. cheyennorum V. and C., from Nebraska but tarsi not ferruginous; it is per- 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. Idaho; Blackfoot, June 22, 1931 (Louise Ireland). Andrena unicula Cockerell, sp. n. Male. Length about 8.5 mm., anterior wing 7 mm.; black, with broad, slightly bluish abdomen; clypeus creamy white with two conspicuous black spots (which are considerably larger than in A. amplificata ) ; antennae black with the flagellum obscurely 156 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

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 October 1933 cockerell, western bees 157 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 159 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- side, California. 160 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 Georyssus minor Sharp, Biol. Centr.-Am. 1, 2, 1882, p. 141, t. 4, 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- October, 1933 hinton— Mexican beetles 161 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.

Paratypes are deposited in the collections of Mr. E. Gorton Linsley, Mr. J. C. M. Gardner, Dr. M. Yano, Mr. M. Kato, the Imperial University of Taihoku, Formosa, the United States National Museum and that of the author. This species differs from C. thaliodes Bates by its bluish colour, smaller size, smoother pronotum, more acute lateral tu- bercles and ungrooved third and fourth antennal segments. The species somewhat resembles C. viridipenne Pascoe, from Borneo. The specimens were found mating, fighting or running on logs of an unidentified species, on a timber trail, at an altitude of a few hundred feet above sea level.

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.

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. Tribe Tillemorphini (Epipedocerini) Genus Halme Pascoe Halme eburneocinctus Gressitt, n. sp. Small, elegant, shiny; red, green, blue, white and black. 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 reddish brown; antennse black, last six segments slightly silvery pubescent; scutellum covered with thick silvery pubescence; elytra October, 1933 gressitt— Japanese longicorns 169 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. Japanese Names 1. Chloridolum loochooanum Gressitt — Oshima-midori-kami- kiri- (mushi) 2.

Halme ebumeocinctus Gressitt — Aokubi-kamikiri 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. — E.

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. 172 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.

October, 1933 HOOD— NEW THRIPS 173 THREE NEW SPECIES OF THRIPS LINNE^' FROM THE WESTERN UNITED STATES BY J. DOUGLAS HOOD University of Rochester The types of the new species described below are in author’s collection. The illustrations were made by Miss Helen Rearwin and Miss Inez D’ Amanda.

Head about 1.2 times as wide as median dorsal length, about as long as pronotum, broadest midway between eyes and base, the transverse anastomosing lines distinct; cheeks rather strongly arched; vertex flattened, not forming an overhanging angulation but sloping nearly evenly from ocelli to frontal costa, this last deeply and somewhat 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 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 THE PAN-PACIFIC ENTOMOLOGIST [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 wings, length 0.698 mm., abdomen, greatest width 0.278 mm.

Utah, Currant Creek, July 22, 1917, sweeping flowers at an altitude of 8,000 ft., James Silver, 3 2 2 [paratypes^. 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 October, 1933 HOOD— NEW THRIPS 175 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 innermost pair longer and stouter than the others and subequal to midlaterals ; other bristles on pronotum shorter and weaker. Wings of fore pair (cut 2, fig. 4) with about 22 bristles on costal margin, 4+3 at base of median vein and 1+1 + 1 in distal two-fifths, and usually 10 (9-12) on posterior vein. Abdomen moderately broad; tergite 8 with the comb on pos- terior margin broadly interrupted at middle; posterior margin of tergite 9 with bristles of inner pair 114 microns long, outer pair 131 microns and lateral pair 148 microns; tergite 10 with bristles 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. 176 THE PAN-PACIFIC ENTOMOLOGIST [VOL, IX, NO. 4 Measurements of holotype ( 9 ) : Leng'th 1.43 mm. ; head, length 0.110 mm., width across eyes 0.146 mm., width just behind eyes 0.138 mm., width across cheeks 0.145 mm.; eyes, length 0.063 mm., width 0.043 mm. interval 0.060 mm.; prothorax median length of pronotum 0.135 mm., greatest width 0.198 mm.; pterothorax, great- est width 0.272 mm.; fore wings, length 0.795 mm.; abdomen, greatest width 0.320 mm. Antennal segments: 1 2 3 4 5 6 7 Length (microns) : 27 41 54 45 37 56 23 Width (microns) : 32 27 22 22 20 21 9 Total length of antenna 0.283 mm. Male (macropterous) . Length about 0.93 mm. Color and struc- ture much as in female. Sternites 3-7 with transversely elliptical tympana, that on 3 about five times as wide as long; tergite 9 with two pairs of bristles in a nearly straight line across middle and a third pair of slightly longer bristles caudad and slightly laterad of the median pair. Measurements of allotype (cT) : Length 0.930 mm.; head, length 0.096 mm., width across eyes 0.140 mm., width just behind eyes 0.133 mm., width across cheeks 0.142 mm.; eyes, length 0.060 mm., width 0.041 mm., interval, 0.058 mm.; prothorax, median length of pronotum 0.116 mm., greatest width 0.188 mm.; fore wings, length 0.600 mm.; abdomen, greatest width 0.240 mm. 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 October, 1933 HOOD— NEW THRIPS 177 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. Prothorax about 1.26 times as wide as median dorsal length,* with distinct, equally-spaced, anastomosing lines of sculpture on notum; sides rounded and slightly converging anteriorly; bristles at posterior angles of moderate length, strong, somewhat curved, and conspicuous because of their dark color, the inner pair about 76 microns long, the outer pair 66 microns long; posterior margin with three or four pairs of small bristles between the two long ♦The specimen figured (Cut 3, Fig, 1) has apparently been somewhat flattened by the pressure of the cover glass. 178 THE PAN-PACIFIC ENTOMOLOGIST [vOL. IX, NO. 4 pairs at angles, the innermost pair much longer and stouter than the others and larger than the midlaterals, the latter stronger and longer than a pair on anterior angles and a pair on lateral fourth behind front margin; other pronotal bristles shorter, but conspicu- ous because of their dark color and large pale insertions. Wings of fore pair (cut 3, fig. 4) with 27-30 bristles on costal margin, 4+3 at base of median vein and 1+1 + 1 in distal two-fifths, and 13-14 on posterior vein. Abdomen moderately broad; tergite 8 with the comb on pos- terior margin wanting in median third, this portion occupied by about six broad, indistinct crenations, as in the whole posterior margin of the basal tergites; posterior margin of tergite 9 with bristles of inner pair 86 microns long, outer pair 116 microns, lateral pair 124 microns, posterior margin of tergite 10 with bristles of inner pair 96 microns, outer pair 92 microns; stemites with the usual three pairs of long bristles on extreme posterior margin but without accessory bristles.

IX, NO. 4 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.

The author beat a single speci- men from Pinus edulis at Yavapi Point on the South Rim of the Grand Canyon, Arizona, on June 7, 1930. It has been com- pared with the type and agrees perfectly with the Colorado speci- mens. — R. L. Usinger. October, 1933 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. 188 THE PAN-PACIFIC ENTOMOLOGIST [vOL. IX, NO. 4 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. — Lawrence W. Saylor.
