July, 1925 IMPORTANT OPUNTIA INSECTS OF THE UNITED STATES: BIOLOGICAL NOTES ON THE MOTH-BORERS (PYRALID^). BY JOHN C. HAMLIN Fresno, California In 1920 the project for the biological control of introduced Opuntias was formally undertaken by the Commonwealth Prickly-pear Board. This project contemplated the intro- duction to Australia of the natural enemies of prickly-pear occurring in the Americas. During the writer’s connection with this work the collecting and rearing of large numbers of the more important cactus insects afforded an oppor- tunity for a general study of their biologies. The necessity of shipping the material intermittently, as well as attention to the bulk rearings, prevented undertaking more detailed biological work. Because of the economic potentialities of these insects it is thought desirable to record the data secured. The results herein contained represent, for the most part, aver- age conditions observed in breeding stocks and in the field over several 3 ^ears. The present paper deals only with the more destructive representatives of that group of Opuntia insects attacking the joints internally. Melitaea prodenialis Walker DESCRIPTIVE Adult. The adult is a large-bodied, sluggish, gray moth with a wing expanse of slightly more than one inch. The fore wings are marked with irregular transverse vittae. Eggs. The eggs are laid one upon another with great precision. The egg-sticks are normally attached to the extreme tips of spines or spinules on the upper part of the plant, being difficult in the field to distinguish from spines. Sticks contain from 20 to 60 eggs, averaging 35. The sticks are usually slightly curved but are often partly coiled. The 2 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 individual eggs are so placed that they resemble tiny, thickened discs. They are elliptical, one diameter being 1.0 mm. and the other, 0.9 mm. In length the egg measures 0.5 mm. Larva. Until about one-fourth grown the larva has a light brown color. Thereafter it assumes a rich, dark blue hue. When full-grown it measures from 30 to 40 mm. in length. Pupa. The dark brown pupa is enclosed in a very tough silken cocoon, often pure white. The cocoon is somewhat less than one inch in length. LIFE HISTORY In summer the eggs hatch in from nine to fifteen days. The small larvae construct a light web about an areole, or where two joints make contact, and beneath this they feed gregari- ously. The web quickly becomes strengthened by the addition of excrement and the dried juices of the plant. When about one-fourth grown they enter the joint and continue to feed together, emitting pellets through one or more openings in the sides of the joint. The change of color described above transpires shortly after the larvae enter the interior of the plant. Normally, they remain within the joints until full-grown. In summer the larval stage extends over from six to eight weeks. Full-grown larvae emerge from the joints and spin their cocoons near the affected plant. The cocoons are usually placed in clumps of three or four, as many as fifteen having been taken in one mass. Sometimes they are found beneath fallen, dried joints and near-by rubbish or placed at the base of an adjacent grass clump. In these instances the cocoons are a beautiful, lustrous white. The majority, how- ever, seem to construct their cocoons in the sand just at the base of the plant, and, in these cases, the cocoons have a considerable admixture of sand and other foreign matter. The duration of the pupal condition in summer is approxi- mately one month. SEASONAL CYCLE There are three generations annually in the region about Miami, Florida. Adults from the overwintering larvae JULY, 1925 ] HAMLIN OPUNTIA INSECTS 3 appear during late February and early March. The mid- summer adults issue in June. The fall brood of moths emerges in October. There are not, however, such definite generations as would be indicated by the above periods. The dates mentioned show the periods of maximum emergence. It is possible to find in the field at almost any season of the year cocoons and all sizes of larvae. HABITS The adults hang motionless from spines during the day. Mating and oviposition occur at night. This insect is much more exacting than Olyca junctolineella as regards conditions requisite for oviposition in cages. Moisture seems to be a most decisive factor. During periods of low relative humidity in the natural range and under normally dry conditions elsewhere, it has been found necessary to sprinkle the cloth of the cages nightly in order to secure more than a few scattered, subnormal egg-sticks. The gregarious habit of M. prodenialis larvae is the particular feature of this species which makes it so much more destructive to Opuntia than its western relative, 0. junctolineella. The average number of larvae found to- gether is about twelve, but as many as twenty-six half- groAvn larvae have been taken in a single small joint. FOOD PLANTS Melitara prodenialis has been found infesting all of the more common prickly-pears of Florida ; namely, Opuntia austrina, 0. drummondii, 0. lata, and 0. keyensis. These Opuntias are comparatively tender and succulent. Rearing experiments showed that this insect will not survive on the tougher western Opuntias such as O. Imdheimeri and O. engelmanni. In Queensland, laboratory results showed that the larvae did not prosper on the “common pest pear,” O. inermis, its texture being somewhat similar to that of the Texas species mentioned. The species of second importance in Queensland, the “Gayndah pear” or “spiny pest pear” (O. stricta), being similar texturally to the Florida species, promises to be quite a suitable host for this insect. 4 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 INJURY TO PLANT The entire damage due to M. prodenialis is accomplished by the larvae. They enter the upper joints and, always feeding gregariously, continue downward from joint to joint, finally invading even the subterranean portions of the plant. Infested plants are rapidly hollowed out, and the remaining tissue, together with a certain amount of larval excrement, is quickly oviposited in by certain scavenging diptera (Volucella esuriens Fabr., V. fasciata Macq., and Neorondania sp.). The larvae of these scavengers are often responsible for considerable extension and aggravation of injury to large plants not completely killed by the primary insect. The effectiveness in Florida of this combination of insects in destroying prickly-pear is abundantly indicated in the field by disheveled lots of dried, whitened, paper-like epidermis on the ground, marking the complete destruction of cactus clumps. DISTRIBUTION Melitara prodenialis has been recorded ^ from New Jersey, Mississippi, and Florida. In the latter State the writer has taken it at Miami, Cocoanut Grove, Larkin, West Palm Beach, Palatka, and Gainesville, and on Biscayne Key. Thus, while the larval habits render this species the most destructive Opuntia insect in the United States, its climatic limitations and the different texture of the western prickly- pears preclude its prospering in our main cactus area. NATURAL ENEMIES Undoubtedly the greatest natural handicap to M. prodenialis in its habitat obtains through the attack of ants upon full-grown larvae after emerging from the plant for pupation in or near the ground. Brachymeria (Chalcis) pedalis (Cresson) is the only para- site observed. The parasitized host larva spins its cocoon normally and completes its transformation. A single adult parasite then emerges from the pupa. This parasite is not at all abundant in Florida and constitutes little or no check upon the moth-borer. 1 The Principal Cactus Insects of the United States, by Hunter, W. D., Pratt, P. C. & Mitchell, J. D., U. S. D. A., Bur. Ent. Bull. 113 , 1912 . JULY, 1925] HAMLIN OPUNTIA INSECTS 5 Melitara sp. Another type of moth-borer was taken in the same pasture at Uvalde, Texas, on three occasions during the summers of 1921 and 1922. Doctor H. G. Dyar, having the opportunity of viewing only a very small number of adults, and in the absence of data upon the immature stages, tenta- tively indicated its identity as Melitara prodenialis Walk.^ Observations on the appearance and habits of the immature stages suggest that this form is perhaps distinct from that species. The three-fourths grown larvae are indistinctly banded, the blue being very pale, and a faint buff suffusion is notice- able over the entire larva. In each instance of collection, from twenty-one to twenty-four larvae were found living gregariously within the heavy basal joints, excreting through several perforations. The dry pellets were some- what webbed and hung from the holes in strings from one to three inches long. Pupation takes place within the chamber excavated by the larvae. The cocoon is very similar to that of M. pro- denialis, being slightly larger. Pupation occurred during September. ^ The adults emerged late in October and lived about one month. The first eggs were laid on November 2. They are deposited in the same fashion as are those of M. prodenialis and O. junctolineella, but the sticks average many more eggs. All egg-sticks contained from sixty to sixty-five eggs each. The incubation period was approxi- mately four weeks. A chalcid parasite which emerged from the cocoons was determined by Mr. S. A. Rohwer as Pareniaca schwarzi Cwfd. Unfortunately no further data were secured to establish the identity of this moth-borer. One portion of the larvae which was shipped to the writer in Australia perished, and the remainder was also lost at Uvalde, Texas, when Mr. E. 2 1 have been informed that additional material of this form has been submitted to Doctor Dyar and he is describing- it as a new species. 3 The further notes on this moth-borer were made by Mr. E. Mortensen. 6 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 Mortensen changed headquarters to Miami, Florida, for the winter. Olyca (Melitara) junctolineella (Hulst) DESCRIPTIVE Adult. The adult is a grayish moth with a wing expanse of one and one-half inches, being larger and more robust than Melitara prodenialis. Eggs. The eggs are somewhat larger than those of M. prodenialis but are arranged in precisely the same manner. The egg-sticks average about twenty-five eggs each. Some sticks have been seen which contained as many as fifty eggs. Larva. The newly hatched larva is about 7 mm. long and of a dark color with a suggestion of a deep blue hue. When from one-half to two-thirds grown they become banded, blue and white. The full-grown larva measures from 40 to 50 mm. in length and has a diameter about equal to that of the ordinary lead-pencil. Pupa. The cocoon and pupa closely resemble those of M. prodenialis , but are considerably larger. LIFE HISTORY The preoviposition period is very brief. Instances were commonly observed where the moths emerged, mated and oviposited within twenty-four hours. The eggs of the spring brood hatch in from five to twelve days. The small larvae immediately burrow into the joint, several often entering the same hole. The joint so affected rapidly blackens and falls to the ground in a few days. The larvae then crawl again upon the plant and enter new joints, thus becoming well distributed over the cactus clump. While the very small larvae live for a brief period in the same joint, they have separate tunnels and are in no sense gregarious. After the early stages the larvae are quite solitary, it being rare to find more than one to a joint. Occasionally two have been found infesting the same joint. After adopting the solitary habit the larva remains con- stantly inside the joint throughout its development. During summer some ten to twelve weeks are passed in the larval condition. When full-grown the larva cuts an exit hole and JULY, 1925] HAMLIN OPUNTIA INSECTS 7 crawls to the ground. The cocoon is spun beneath fallen cactus joints or other debris near the base of the plant, or may be placed just below the surface of the soil. The appearance of the cocoon is affected by its location, those spun on the joints being a beautiful white, while those in the ground are mixed with soil. Transformation takes place shortly after completion of the cocoon, and the pupal stage extends over about four weeks. The length of all stages of the fall generation is somewhat longer. SEASONAL CYCLE Throughout Southern Texas, 0. junctolineella has two generations yearly. Thus, during three-fourths of the year the species exists in the larval stage, both the winter and the dry, hot summer being passed in that condition. The periods of emergence and oviposition coincide with the normally rainy months of the spring and fall. At Uvalde, Texas, the spring brood of moths issues during May and early June, the maximum emergence obtaining during late May or early June. These moths produce the summer larv^ which pupate from late August through September. The peak of emergence of the fall moths occurs about the first of October, and these give rise to the overwintering larvae. The winter larvae require about five and one-half months to become full-grown. Pupation extends over the latter half of March and through April. The upsetting of the seasonal cycle by transportation into the opposite seasons of Queensland and the promise of becoming a three-generation species there has been recently recorded. ^ HABITS The adults are inactive by day. The usual position is to hang from a spine by the second and third pairs of legs, with the front legs folded close against the head, resembling the palps. Mating and oviposition occur during the night although some few pairs have been noted to remain in copulation during the following forenoon. Many attempts to observe the manner of oviposition were futile. 4 Seasonal Adaptation of a Northern Hemisphere Insect to the Southern Hemisphere, by John C. Hamlin, Jl. E'c. Ent., V. 16, No. 5, pp. 420-424, 1923. I 8 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 The larvae are quite solitary. Usually only a small num- ber are found in a cactus clump, despite the large number and arrangement of the eggs. Cannibalism, if it occurs at all, is not of sufficient prevalence to account for this condi- tion. In the rearing of huge numbers of individuals, it was necessary to place together large numbers of the larvae from the moment of hatching until pupation occurred, thus offering an opportunity for the display of cannibalistic tendencies rarely, if ever, obtaining in nature. Despite such conditions there were no indications of cannibalism. The explanation of the condition cited probably lies in the activities of ants as shown elsewhere in this paper. The rapidity with which a half-grown larva can enter a fresh, solid joint is one of the most remarkable feats of the species. The silicious cuticle is quickly punctured and the larva disappears in an incredibly short time, considering the density of the medium. This is accomplished by the larva passing the pulp immediately through its body. FOOD PLANTS During the entire period of the writer’s observations the species has been found feeding only in prickly-pear. The favored species are Opuntia Undheimeri and O. engelmanni. In Queensland the species has prospered, under laboratory conditions, on both 0 . inermis and 0. stricta. Prickly-pear plants set up a strong reaction to wounds of any kind. Numbers of instances have been observed in rearing cages where the exuding juices have drowned the larvae which punctured the epidermis. This condition is much more frequent in cages where, because of crowding, the larvae are forced to enter new joints many more times during their existence than in the field. Nevertheless, many larvae perish in this manner under natural conditions. The prickly-pears of the ficus-indiccc group show a greater degree of this type of resistance to larvae of 0 . junctolineella than do the other Opuntias. CHARACTER OF INJURY Newly hatched larvae are responsible for the outright killing of many joints. The summer brood of larvae, appear- ing simultaneously with the spring growth of the plant, is JULY, 1925] HAMLIN OPUNTIA INSECTS 9 responsible for the destruction of large numbers of the young fruits. The most reliable indication of injury is the characteristic swelling of the joints in which larvae are developing. The larva hollows out a chamber and packs excrement in the lower part of the cavity. The tissue within is completely destroyed and the proliferation of such parts increases the thickness from two to four-fold. When full-grown the larva cuts an exit hole through one side of the swelling and leaves the joint to pupate near the base of the plant. The larval exit hole permits the several scavenging flies (V olucella esuriens Fabricius, V. avida Osten Sacken, V. fas data Macquart, V. pusilla Macquart, Copestyhim mar- ginatum Say, Hermetia illucens Linn., H. chrysopila Loew, and H. hunteri Coquillett) to oviposit within the swollen portion. The maggots find ideal conditions in the excrement of the former inhabitant and the moisture from the injured plant tissues. These maggots are, during their development, able to extend the damage so that further healthy areas of the joint are invaded. In those instances in which exit holes were placed high enough to prevent the draining away of the resulting liquefaction, this secondary injury may be extended into the next joint below. The net result is the death of joints so affected. Occasionally a swollen joint is found which contains no larva and which is without an exit hole. In view of the plant resistance already noted, it is believed that such missing larvse were overcome by the plant reaction after the cavity had been started. In such joints the swelling diminishes greatly but the sides do not reunite. DISTRIBUTION Olyca junctolineclla occurs throughout the cactus area in Texas. During the writer’s observations it has been found most abundant in the Uvalde, Texas, region. It has also been taken at many points in Mexico as far south as Cuernavaca, State of Morelos. The writer observed one larva in an Opuntia growing on the floor of the Grand Canyon in Arizona which appeared to be of this species. 10 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 NATURAL ENEMIES. PARASITES A number of parasitic insects appeared in rearing cages containing field-collected material, but only a portion of them may definitely be listed as parasites of this moth- borer. Apanteles miinoristcB Muesebeck is perhaps the most im- portant. The parasitized host larva attains full size and spins its cocoon normally, except perhaps for being of lighter construction. The host larva is destroyed just before pupation, and shortly the Olyca cocoon is found to contain large numbers of the Apanteles cocoons. The number of adult parasites emerging from one host cocoon was found to vary between twenty-five and ninety. On one occasion observations were made upon the happenings in small fruit jars to which had been added Olyca larvae, Apanteles adults and a cactus joint. The parasites would not ovipost in the newly hatched larvae. Their constant reaction on touching these small larvae dur- ing their rapid crawling about the jar was merely indicative of increased excitement and hurried avoidance. When placed with Olyca larvae about one week old, the parasites oviposted deeply within the larvae immediately upon finding them. The ovipositor was often allowed to remain inserted several seconds while the larva twisted and squirmed. The larvae were so pierced a great number of times during the observation. These larvae when subsequently placed upon Opuntia, entered it and fed normally for some two weeks when the lot was abandoned preparatory to a change of head- quarters. These observations indicate that, in the field, this parasite oviposits in the larvae at the time they leave the originally infested, fallen joints and crawl again upon the plant to enter new joints. Pareniaca schwarsi Cwfd. and Chalcis pedalis Cress, have been found as common, though not abundant, parasites of 0. junctolineella. Second in importance to the Apanteles above mentioned are Frontina aletice Riley and Phaonia n. sp. These dipterous parasites affect the host larva similarly to Apanteles JULY, 1925] HAMLIN OPUNTIA INSECTS 11 mimoristcE, the puparia appearing within the host cocoon shortly after the latter is spun. The numbers are not nearly so large, however, usually from four to eight being present. PREDATORS This species is subject to attack by ants, not only as mature larvae seeking the ground for pupation, but also as small larvae emerging from originally entered joints which fell to the ground under the combined attack of the newly hatched larvae from one or several egg-sticks. It has been noted above that the falling of joints infested with small larvae brings about the distribution of the larvae over the cactus clump. It is believed that the depredations of ants at this time are responsible for the scarcity of larvae in the average clump.

S. records of this species are rare. Lindsey records a specimen from Brownsville, Texas, Barnes collec- tion, but Skinner and Williams have apparently overlooked this and record only the Runyon catch from Southern Arizona or California. Mr. O. C. Poling recently sent a specimen from the Baboquivari Mts., Pima County, Arizona, 20 September, 1924. This we submitted to Mr. Shaus for comparison with his Mexican specimens as the markings are somewhat darker than those of the Texas specimen before us. Polia stricta race kappa Barnes & Benjamin, nov. Head and thorax ferruginous, more or less darkened by black scales. Abdomen luteous, tinged with rufous. Fore wing variable in color, the ground color some shade of luteous, suffused with bright ferruginous red and more or less darkened by black scales, in general the ferruginous cast dominant; basal maculation indistinct but basal dash usually present on the freshest specimens. Ordinary lines, spots, and maculation, as in typical stricta. Hind wing of 6 white, the veins and outer margin more or less soiled by fuscous. An obsolescent discal spot. Fringe white at tip, with an obsolescent interline and yellowish-white base. Hind wing of $ similar but with more fuscous on it. Expanse : 6 , 23-28 mm., 2 , 24-28 mm. Similar to typical stricta but differing from all described forms by the much paler hind wings which are nearly as white as those of spiculosa. JULY, 1925] BARNES AND BENJAMIN LEPIDOPTERA 13 At first we considered the present subspecies to be tenisca and may have determined it as such for other collections. “ M amestra” tenisca was described by Smith from a series of specimens from Bozeman, Montana, and Stockton, Utah, the type 6 being a Bozeman specimen in the Smith collec- tion. The recent acquisition of a series of specimens from both of the type localities of tenisca show that Nevada material is not quite typical as it varies from forms nearly as pale as kappa to forms as dark, as tenisca. The specimen from Reno, Nevada, figured by Barnes & McDunnough (1913, Contrib. N. H. Lep. N. A., II, (1), 22, pi. X, f. 10) seems nearly typical of 9 tenisca. While all forms of stricta seem more or less variable in each locality, and Nevada material is intermediate, producing some specimens which can be placed under any of the present subspecific names, nevertheless our series of the white hind winged form is so distinct from the variations found in the type localities of the described subspecies, and in itself is so constant with its pale secondaries, that we have no hesitation in describing it. Type locality: Inyo County, California, mostly from Round Valley. Nimiber and sexes of types: Holotype 6 , 15-30 Aug., Allotype 9 , 220 Paratypes, both sexes, various dates Aug., Sept., Oct.; O. C.

Thoracic crest large, marked by a slim black stripe. Abdomen basally gray, caudally more ochreous. Fore wing dull ash-gray, the costal region somewhat paler than the remainder of the wing. Ordinary lines and spots obsolescent, nearly obsolete; no basal line or dash; t. a. line marked by a few black scales; median line similar; their course indeterminate. Orbicular absent; reniform mainly visible as a slight rufous cast at end of cell. T. p. line so poorly marked its exact course cannot be seen, but apparently with a tendency to be produced to points on the veins and to be bent inward in submedian fold where it shows as a V pointed inward, and is connected to a pointed clavi- form by a small black bar. S. t. line indicated by a few scattered black scales. Veins of terminal area slightly darkened. Fringe a little browner than the wing color and obscurely interlined. Hind 14 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 wing pale red-brown with a decided pinkish cast; usual discal dot and terminal line present but not conspicuous. Fringe pale, whitish tinged with pink. Beneath: dull; fore wing gray tinged with pink; hind wing whitish tinged with grey and pink. Discal dot present on each wing. Expanse: 36 mm. Allied to fagina and itata. Smaller, duller, and darker than the former, with the markings not so distinct, but although at once separable, closely allied by the paler costal area, lack of a basal dash, and the proximity of the claviform to the t. p. line, leaving room for only a very short black dash in the submedian fold. Closely allied to itata, with which it agrees in wing-shape, size, and general color. In true itata, as represented by the types, there is a tendency for the transverse maculation to be obscured, but the black dashes in the reniform, and the median and subterminal parts of the submedian fold are distinct, as is the subapical shade. While the present species has the distinct bar in the submedian fold connecting the claviform to the t. p. line, the remainder of the longitudinal maculation has been so reduced that it is invisible except for the faint indication of a few black scales, while the orbicular is entirely absent and the reniform mainly indicated by a reddish suffusion. The legs of the present species lack the strong longitudinal black lines present, one on each leg, of allied species. Type locality: Douglas, Arizona. Number and sexes of types: Holotype 6 , 16-23 June, unique, in Barnes collection. Xanthothrix ranunculi form albipuncta Barnes & Benjamin, nov. Head, thorax and fore wing black dusted with olivaceous, the latter with a round white spot near end of cell. Sec- ondaries blackish. Other characters as in ranunculi which is a very variable species. Expanse: 6,11 mm.; $ , 10 mm. No mention is made in the original description of ranunculi of any white spotted form, nor do the types in the Henry Edwards collection show any traces of spots on the primaries.

Poling, Babo- quivari Mts., Pima County, Arizona, 1-15 August 1923, which agreed well with Druce’s figures and with a specimen from Mexico, ex Kearfott collection. A second specimen has been received from Dr. Vorhies of the Arizona Experi- ment Station bred from prickly-pear and labeled Santa Rita Mts., Arizona, VI-23-24. This species, described from Mexico, was recorded in Dyar’s list from Arizona, presumably by Prof. Fernald. In view of the recent research in insect enemies of the prickly-pear, this note may be of some importance. The insect is a member of the Pyralid subfamily Pyraustinge, is of large size and decided possibility in the control of the cactus. The Van Duzee Collection of Hemiptera At the regular August meeting of the California Academy of Sciences, Mr. E. P. Van Duzee presented to the Academy his entire collection of Hemiptera under practically the same con- ditions under which the Van Dyke Collection of Coleoptera was accepted by the Academy last year, as announced in this journal (Vol I, page 13). Under these conditions he retains general supervision over the collection during his lifetime with the privilege of temporarily withdrawing for study any of the specimens he may need for use at home. He also stipulated that each specimen in this collection is to have attached a label to read “E. P, Van Duzee Collection,” and that all these specimens are to be incorporated into the systematic collections of the Academy and that they are not to be used for exchange or for exhibition purposes. These conditions secure to him the use of the material during his lifetime and safeguard it against being dissipated or lost through carelessness or mismanagement in the future. 16 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

Fore wing: ground color gray heavily irrorated and overlaid by black, with some rufous suffusion, and a purplish tinge; basal line obsolescent, waved; t. a. line double, its course slightly outwardly oblique, as outcurved crescents, from costa to median vein, thence to vein 1, and to inner margin; orbicular and reniform not large, faintly outlined by black, pale filled, the filling obscured by dusky central marks and heavy powderings, more or less red tinged, which shade extends beyond the cell to the t. p. line; claviform moderate to small, variable, distinctly outlined by black, filled with a rufous shade which continues to the t. p. line; t. p. line double, black, its outer line indistinct, angled outward below costa, thence oblique to about vein 5, thence incurved, produced to a strong outward point on vein 1, otherwise produced to moderate points on the veins; s. t. a yellowish wavy line defined on both sides by black and terminating in a moder- ately large, black defined, spot at tornus; a thin black terminal line; fringe fuscous-gray, with darker interline and tips, paler basally. Hind wing: nearly uniformly fuscous, the veins slightly darker; fringe luteous at base, with fuscous interline and pale tips. Beneath: with a dark common line; in general fuscous, the hind wing some- what paler basally; discal spot obsolete on fore wing, obsolescent on hind wing; fringes as on upper side. Expanse: 6, 27-32 mm.; 9, 30-31 mm. Closely allied to rubrifusa Hamp., but the uniformly dark secondaries easily distinguish it. P. gnata Grt. belongs to the same group but its type, in the Neumoegen collection, possesses white hind wings P. agnata Sm. is also allied * Indicates specimens were submitted to Dr. William Scliaus in order to ascertain that the species had not been described from south of the U. S. border. 2 A further discussion of gnata and several other types in the Neu- moegen collection has been incorporated in a separate paper. 3 We wish to call attention to the fact that male agnata Sm. has serrate antennae, and if Hampson’s characters are employed, belongs to this group. Also that segregata Sm. and gussata Sm. are incorrectly placed on our lists, having serrate male antennae and being closely allied to pUcata Sm. and negussa Sm. In fact, we suspect that negussa is simply smooth gussata, and the same may be true between segregata and pUcata. Careful study, based on abundant material, will be necessary to ascertain the exact relation- ship of these four names. JULY, 1925] BARNES AND BENJAMIN PHAL^NID^ 17 Locality: White Mts., Arizona.

M., VIII, 544, type designated licentiosa, but erroneously placed as section I of Namangana. 1923, Barnes & Benjamin, Bull. B’klyn Ent. Soc., XVIII, 123, type designated licentiosa; licentiosa = dentatella, Eupolia = Trichopolia. We describe the following species in Trichopolia although our three specimens lack a dorsal tuft on the second abdominal segment. This tuft in dentatella is easily lost, is only visible on some specimens and as all other characters seem very similar, we think the tuft has probably been rubbed off our types of suspicionis. Structurally the species would appear to fall into Hamp- son’s Nephelistis. We have already pointed out (1923) that Hampson drew his description of the genus Trichopolia from specimens of ursina Sm., and found it necessary to erect the genus Engelhardtia for type ursina. 18 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 We do not know if the genus Nephelistis will fall into the synonomy of Trichop olia or not. Certainly it seems very closely allied, and mainly separated on secondary sexual characters. Trichopolia comes very close to Scotogramma, but the front is not as much rounded out. It is also closely related to Folia, and some species now placed in Eriopyga. Most of these hairy-eyed genera need careful study to ascertain which should be retained and what species placed in them. Tentatively we place Trichopolia between Admetovis and Lophoceramica. This placement between Trichoclea and Chabuata brings Trichopolia into contact with its obvious exotic affinities, which possess pectinate antennae in the male sex, such as Hydroeciodes and Nephelistis. Trichopolia suspicionis* Barnes & Benjamin, n. sp. Male: Antennae bipectinate, apically serrate and simple, ciliated. Mid tibiae with tuft of long hair but not conspicuously dilated. $ antennae simple, the joints slightly marked, ciliated. Androconia absent in both sexes. Palpi pale, marked with black on sides, second joint reaching about middle of frons, third joint porrect. Head and thorax brown irrorated with black, abdomen similar, with dorsal tuft on basal segment only; and slight lateral tufts. Fore wing: ground color dull wood-brown, grayed by a scattering of black scales; transverse lines single, black; basal line from costa to the end of a short basal black dash, forming a loop; t. a. line outwardly oblique from costa to inner margin, only slightly excurved; claviform obsolescent; orbicular pale, moderate, slightly oblique, faintly outlined by black and with black powdered center; reniform centrally constricted, edged with an obsolescent series of black scales, then a pale faint line followed by a strong black edging, centrally with a blackish outlined inner crescent, the whole mark heavily powdered by black; t. p. line erect on costa, strongly excurved around cell, inwardly oblique, only a little incurved, below; s. t. line obsolete; terminal line thin, broken by veins; fringe pale, checkered by black. Hind wing: whitish, subhyaline, with small discal spot and darker veins, some fuscous suffusion outwardly; a thin terminal fuscous line; fringe white, obsolescently interlined, and with yellowish base. Beneath: whitish; the fore wing more or less suffused with fuscous, especially in cell and on veins, with discal spot and t. p. line showing through, terminal line and fringe as on upper side; hind wing with only a scattering of fuscous scales, mostly on veins; ter- minal line and fringe as on upper side. Expanse: 26-28 mm.; 2, 26 mm. JULY, 1925] BARNES AND BENJAMIN PHAL^NIDJE 19 From the only allied species, dentatella, known to us, the present species differs by the pectinations of the male antennae being but about half as long, while the general coloration is much paler, the transverse lines much stronger and blacker.

II, NO. 1 Athetis Hbn. as used by Hampson is apparently correct in place of Caradrina as used in the Barnes & McDunnough Check List. Caradrina has type i-intactum by Duponchel, 1829, and will likely replace Lycophotia Hbn. as used by Hampson and Barnes & McDunnough. Elaphria Hbn., placed by Hampson as a synonym of Athetis was first described in the Zutr. Exot. Schmett., I, pi. XHI, grata sole species and therefore type. This will have priority over the monotypic genera Monodes Gn. (type nucicolora Gn.) and Alpesa Wlk. (type villicosta Wlk.) Athetis indigena* Barnes & Benjamin, n. sp. Palpi cream-colored, black at the sides. Head and thorax pale brownish with a violaceous cast. Collar with a broad black band at its base, else concolorous with the thorax. Abdomen pale brownish above, yellowish beneath, the genitalia of the male surrounded by long yellow hair. Fore wing: ground color dull pale wood brown, with a slight violaceous tinge and a silken lustre, darkened and grayed by scattered black scales, lines black; basal line geminate, its outer line indistinct, waved from costa to submedian fold, obsolescent below; t. a. line geminate, its inner line obsolescent, appearing as a dot on costa and again as a thin irregular line from costa to inner margin; orbicular obsolescent, more or less indicated by a faint ring of black scales; claviform obsolete; reni- form indistinct, black centered due to intersection by an obscure median shade, marked by four pale yellowish points; t. p. line faintly geminate, the inner line stronger, as a dot on costa excurved around cell, incurved below, produced to points on the veins; s. t. obsolescent, its course indicated by a faint yellowish shade which is marked in- wardly by slight dusky shades and one or two black dashes; a thin terminal line broken by the veins; fringe luteous at base, dark and obscurely interlined. Hind wing: 6, whitish, subhyaline, the veins and outer portion darkened by fuscous; $, darker, almost appearing fuscous; fringe yellowish at base, with gray interline and white tips. Beneath: whitish, the fore wing largely suffused with fuscous with slight discal dot and transverse line; hind wing with scattered fuscous scales mainly along veins and toward the outer margin which is somewhat darkened, with discal dot and transverse line: fringes, all wings, as on upper side: sexes similar on under side. Expanse: 6, 29-32 mm.; 2, 31-33 mm. Allied to triquetra, with a similar set of black subterminal marks but lacking the black in the costal-subterminal region ; at once distinguishable by the entirely different type JULY, 1925] BARNES AND BENJAMIN PHAL^NID^ 21 of reniform and the black at the base of the collar. It is also considerably heavier in build. Perhaps triquetra and indigena should be placed in Ariathisa; but we prefer to retain them with their North American allies. ''Caradrina” derosa Morr., is placed by Hampson as a synonym of capularis Gn,, but a figure of the type would indicate that it might be more nearly related to indigena. We know of nothing like this figure, which does not seem to match Hampson’s plate CXXXII, figure 12 of capularis; having strong black markings on the reniform. Not know- ing how much capularis varies, we hold the status of derosa in abeyance. Even if distinct from capularis it is probably exotic.

The species is rather variable. It also appears somewhat sexually dimorphic, the males darker marked and lacking the yellow found in the transverse lines of the females. This is replaced by rather diffused black. 22 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 A NEW ACINOPTERUS FROM SOUTHERN CALIFORNIA BY HERBERT OSBORN Acinopterus aridellus Osborn, n. sp. Head scarcely as wide as pronotum, vertex broad, distinctly angulate, with a faint transverse depression, one-third longer at middle than next the eye, longer and more pointed in male, front broad, tapering uniformly from antennal pits, clypeus long, expand- ing towards the tip, lorse large, nearly touching margin of cheek, cheek margins sinuate, pronotum a little longer than vertex, elytra long, apex rather broad, acute at tip; female last ventral segment twice as long as preceding, hind margin rounded, minutely notched at tip; male valve concealed or wanting, plates narrow, long, reaching nearly to tip of pygofer. Color: dark gray, suffused with pinkish, especially at tip of vertex and on the elytral veins; ocelli whitish, three obscure whitish lines on the pronotum, extending on to the scutellum; elytra hyaline, the veins whitish, or tinged with pink, and margined with fuscous; beneath yellowish, tinged with pinkish. Length ; male and female, 4.5-5 mm. Described from one female (type) two males, (allotype and paratype) collected by the writer at Palm Canon, Imperial County, California, March 8, 1924. They occurred upon a small creeping plant outside the canyon mouth and amongst barrel cactus, creosote, and sagebrush, in distinctly arid conditions. It is decidedly smaller, especially more slender, than acuminatus or angulatus, and the vertex is longer, especially in the male, where it is quite distinctly angulate. Type in Author’s collection. Two Arizona Hemiptera Ganocapsus filiformis Van Duzee was taken by me in large numbers on a species of sunflower at Patagonia, Santa Cruz County, Arizona, about the first of August, 1924. It occurred on other weeds and grasses in the same locality, but seemed to be breeding on the sunflower only. With it were taken numbers of Garganus splendidus Distant, not before recorded from north of the Mexican border. — E. P. Van Duzee. JULY, 1925] CHAMBERLIN SCOLYTID^ 23 THE CONIFEROUS TREES OF THE UNITED STATES WITH THE SCOLYTID (IPID) BEETLES SAID TO ATTACK THEM BY W. J. CHAMBERLIN Oregon State College Corvallis, Oregon The following list contains such coniferous trees as are reported to be the host of one or more of the bark or ambrosia beetles. This list has been compiled from all available literature, from field and laboratory records of the Oregon Experiment Station, from ten years collecting in the western forests by the author and lastly from material obtained by exchange. Although the list is far from complete and some of the records as given in literature, especially in the older papers, are probably inaccurate, it is felt that this preliminary list will prove of value and may stimulate others to check it carefully and make known any errors, corrections or addi- tions so that a more complete and accurate list may be compiled at a future time. A few of the rarer trees are not listed, since no record of their being attacked by scolytids, has been noted. Un- doubtedly all of them have their scolytid enemies and investigation of such trees should be carried on by those so situated as to be able to do so. Mr. Ralph Hopping’s paper, “Coniferous Hosts of the Ipid^ of the Pacific Coast and Rocky Mountain Region,” which appeared in the Canadian Entomologist, Vol. 54, pp. 128-134, has been of great value in compiling the present paper. The trees are listed alphabetically, according to genera and species. 1. Abies amabilis. Lovely fir Cryphalus amabilis Chamb. Gnathotrichus retusus (Lee.) sulcatus (Lee.)

ROCKWOOD U . S. Bureau of Entomology, Forest Grove, Oregon Published records of night flying and attraction to light in the family Acridiidse of the Orthoptera appear to be few and not readily discoverable. This behavior has been well established for Dissosteira longipennis Thomas in Colorado ^ and New Mexico ^ and a recent article ^ would indicate that this species was the only one in the United States known to fly at night. A search of the literature at hand at this moment, however, adds several species to the list of those taken at light at night, and the observation recorded in this paper adds three more. Riley, Packard, and Thomas ^ were apparently able to find but one authentic case of observation of flight of Acridiidse at night in European literature and mention none for America. They pointed out, however, that circum- stantial evidence indicated that migratory flights may be continued after nightfall. A flight of large numbers of grasshoppers, thought to have been Schist ocerca americana Dru., was noted ^ at a lighthouse in Lake Erie off the mouth of the Detroit River between the hours of 11 and 12 p. m. on the night of July 12, 1899. Mr, W. R. Walton of the U. S. Bureau of Entomology has stated in correspondence, and given permission to quote that, in the vicinity of Washington, D. C., “we frequently find considerable num- bers of the Carolina grasshopper, Dissosteira Carolina Linn., flying around the electric lights during the warm nights of the summer.” 1 Circular 36, 13th annual report, State Entomologist of Colorado, p. 35, June, 1922.

A study of these records indicates that night flying of Acridiidse may frequently occur in the Southwestern United States, while nocturnal activity in this family would seem to be of rare occurrence in northern latitudes. It is, there- fore, thought to be worth while to record the following observation made by the late Prof. A. L. Lovett of the Oregon Agricultural College and the writer, together with pertinent meteorological data. On the night of July 22, 1923, Professor Lovett and the writer were in the city of Boise, Idaho, after a sweltering day on the train. At about 9 :30 or 10 p. m., w^e decided to take a short stroll in the open air for the purpose of cooling off. Our attention was almost immediately attracted to grasshoppers which were fluttering around the street lamps like moths. Several of the grasshoppers were on the sidewalk where many had been stepped on and mangled by pedestrians and we each collected a double handful of the hoppers from in front of show windows and doorways. These grasshoppers have since been identified by the writer as follows : Conozoa ‘ivallula Scudder, 3 2 2 Dissosteira spurcata Sauss., 6 6 6,322 Spharagemon txquale Say, 5 6 5,522 5 Proc. Acad. Nat.

Department of Agriculture, Boise, Idaho, has kindly furnished the following meteorological records for July 22, 1923 ; Temperature Wind direction ^Relative humidity 7 89° at 8 p.m. W at 7 p.m. 25 per cent at 6 p.m 86° at 9 p.m. NW at 8 p.m. 80° at 10 p.m. N at 9 p.m. 77° at 11p.m. N at 10 p.m. maximum for day, 98° SE at 11 p.m. It is the opinion of the writer that the high night tempera- ture was the principal factor occasioning the night flight of grasshoppers in this case, although the relative humidity, wind direction, and the extreme heat of the preceding day- light hours were doubtless also important factors. It is a well known fact that temperature is a prime factor in deter- mining the activity of grasshoppers. Sviridenko ® and Parker ^ have recently reported that air temperatures in the neighborhood of 80° F. occasion maximum activity in the case of Dociostaurus maroccanus Thnb. and Camnula pellucida Scudder, respectively. Parker ® has recorded much valuable data on the relation of meteorological conditions to the behavior of the latter species. In this paper it is stated that migratory flights “did not begin (in Montana) until the air temperature had reached 74° F. and were at their maxi- mum at from 75° F. to 78° F.” Other data in the same article indicated that the temperature limiting the inaugura- tion of short flights in Minnesota is near 75° F. Both authors agree that air temperatures in the neighborhood of 90° F. tend to inhibit activity in these species. 7 A trace of precipitation was recorded for the 23rd, so that the per- centage of relative humidity was probably considerably higher at 10 p. m. 8 Sviridenko, P.

JULY, 1925] HUBBELL PRISTOCEUTHOPHILUS 39 A NEW SPECIES OF PRISTOCEUTHOPHILUS FROM THE OLYMPIC MOUNTAINS, WASHINGTON. (Orthoptera, Tettigoniidge) ^ BY THEODORE H. HUBBELL Gainesville, Florida The expedition to the Olympic Mountains of Washington, sent out in the summer of 1919 by the Museum of Zoology of the University of Michigan, brought back a small collec- tion of the Orthoptera of the region. Only a few species are represented, as the party left the field before most of the Orthoptera had become mature. Nevertheless the col- lection contains several species of the subfamily Rhaphi- dophorinse which are of unusual interest; one of these proved to be new, and is described below. Pristoceuthophilus gaigei Hubbell n. sp. Related to P. tuberculatus and P. cercalis, but easily dis- tinguishable from all species of the genus hitherto described by the distinctive armament of the dorsum of the male abdomen, the form of the male cerci, and the coloration. Description of holotype male Size small for genus. Head with frontal spine well developed, but shorter and blunter than in celatus and pacificus. Antennae slender, with approximately 120 segments, more than twice as long as body. Pronotum slightly longer than exposed portions of meso- and metanota together. Ventral margins of thoracic terga gently arcuate, with ventro-cephalic and ventro-caudal angles rather abruptly rounded. Pronotum and mesonotum smooth; metanotum with a group of small, blunt-pointed tubercles on each side of dorsum, covering most of exposed lateral portions of tergum, but not reaching ventral border. Terga of abdominal segments I to VIII armed with large, heavy, blunt-pointed spines, or with rounded or conical tubercles; dorsum of segment IV elevated into a large median prominence of dis- tinctive form. Spines and tubercles of each abdominal segment arranged in two slightly irregular transverse rows along caudal margins of terga, except on VIII, where cephalic row is absent. On I to IV the spines (smallest on I) confined to lateral and dorso- lateral portions of terga; dorso-lateral spines largest (some measure .7 mm. in length), decreasing in size ventrad. Dorsum of segments 1 Contribution from the Department of Biology, University of Florida. 40 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 I to III unarmed. Tergum of III narrower dorsally than the rest, crowded forward by enlarged dorsum of IV, which bears, in median line, a large, tall, smooth protuberance of peculiar shape (see figure) which is approximately three times as long as dorsal length of segment III. Segment V armed similarly to segments I to III, but caudal row of spines continued across dorsum (the dorsal spines being, however, much smaller than those of sides), and cephalic row represented on dorsum by paired lateral spines and a row of conical tubercles. Segment VI with same arrange- ment as V, but dorsal spines of both rows larger; spines of cephalic row irregularly spaced, and only about one-half the height of those of caudal row. Segment VII with spines of caudal row reduced to about half the size of corresponding ones of VI; cephalic row reduced to an indistinct line of rounded tubercles. Segment VIII with cephalic row absent; caudal row re- duced to a line of rounded tubercles. On all abdominal segments except I the spines or tubercles of the caudal tend to be larger than those of the cephalic row; this is most marked in segments V to VIII, in the last of which no trace of the cephalic row remains. On segments II and III the armature almost reaches the ventral borders of the terga; posteriorly the distance to the ventral margin increases, until on VIII the tubercles are confined to the dorsum. Supra-anal plate (tenth tergite) laterally narrow, with gently con- cave latero-caudal margins, produced mesially in a strongly depressed triangular lobe. Subgenital plate (hypandrium) subquadrate, nar- rowing distally; distal margin broadly and shallowly emarginate, disto-lateral angles rounded. Styles short, robust, bluntly pointed, with faint indications of segmentation.. Penis fully extruded; ventral lobe sub-chitinous, densely clothed with fine retrorsoappressed spinules; longer than broad, with rounded tip (which hides distal portion of supra-anal plate in type). Cerci similar in form to those of cercalis and tuberculatus. The length of cercus to tip of basal unsegniented portion about two- thirds the length of the pronotum. Legs moderately stout. Cephalic femora unarmed. Median femora armed on both margins (left) or on caudal margin only (right) with a very minute sub-apical spinule. Median tibiae armed dorsally with 2 The artist has correctly shown the main features of the abdominal specialization, but the figure contains some minor inaccuracies with regard to proportions and spine arrangement.

Caudal femora slender, unarmed dorsally; both ventral carinse armed in distal half with distant, minute, sharp-pointed spinules, more numerous and closely spaced on caudal than on cephalic margin, the apical ones larger than the rest. Hind tibiae straight, with no trace of basal curvature or ventro- proximal lamination. Length of antennas approximately 21 mm.; of pronotum 2.6 mm.; of cephalic femora 3.4 mm.; of caudal femora 7.0 mm.; of caudal tibi^ 8.3 mm.; of cercus to tip of unsegmented basal portion 1.6 mm. Coloration®: Antennae honey yellow; joints of distal portion in- fuscated in proximal half; marked with lighter annuli at irregular intervals. Head barium yellow, with indistinct markings of Vandyke brown below eyes and antennal sockets, and on median frontal line. Frontal spine black, the ocelli on its sides bright sulphur yellow. Eyes black. Occiput barium yellow, with markings of vandyke brown between eyes. Thorax barium yellow on dorsum, lighter and semi-translucent along ventral margin. Two broad brownish black dorso-lateral stripes border the light-colored median area. They are most distinct on caudal portion of pronotum and on mesonotum; on cephalic half of pronotum less densely colored, and marked with small yellowish maculations. Light median stripe abruptly narrowed in middle of pronotum by convergence of dark bands cephalad; from this angulation faint longitudinal streaks of Vandyke brown extend caudad within margins of median band. Abdomen with dorsal surface ocher yellow, caudad faintly marked with longitudinal brownish lines; spines and median protuberance ochraceous tawny. The dark bands of thorax extend caudad less distinctly along sides of abdomen. Cerci barium yellow proximally, shading into reddish brown at distal end of unsegmented portion; terminal segment of distal portion barium yellow. Caudal femora honey yellow dorsally, indistinctly suffused with brownish on ventral surface; outer ventral carina marked with distinct alternating light and dark patches. Traces of color pattern similar to that of cercalis visible on pagina. Remaining femora and tibia honej'' yellow, faintly marked with brownish. Specimens examined: One (holotype male), Lake Cush- man, Olympic Mountains, Mason County, Washington, August 1, 1919 (F. M. Gaige). (In collection of Museum of Zoology, University of Michigan.) A single immature female taken June 25, 1919, in the same locality shotvs a similar type of coloration, and may belong to this species. 3 Where definite color names are used the terminologj* is that of Ridgway’s Color Standards and Color Nomenclature. 42 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 Prist oceuthophilus gaigei is more bizarre than any species of the genus hitherto described, and one of the most peculiar of North American Orthoptera. It is most closely related to P. tuberculatus and P. cercalis, but far surpasses both of these species in degree of specialization of the male abdomen. All three species have the same form of male cercus, a more specialized type ^ than is found in other members of the genus. P. tuberculatus approaches closer to gaigei in the character of the male dorsal abdominal armament than does cercalis. The function (if it has one) of the peculiar median prominence on the dorsum of the abdomen can only be sur- mised. It may be noted, however, that on the concave sides of the structure there are two elongate light-colored areas, Avhich are connected across its dorsum at the nar- rowest point; these areas are not heavily chitinized, but seem to be membranous. It is possible that they may con- tain the openings of scent glands, or perhaps mark the site of an eversible scent organ. I have named this species in honor of its collector, my friend, Mr. F. M. Gaige. His field notes on the type are as follows : “In rotten logs in clearing on Staircase Trail, Aug. 1.” Mr. Gaige informs me that these logs were in an apparently natural clearing in maple-alder woods, with underbrush of stag-alder, vine-maple and willows, which bordered the dense conifer forest, the edge of Vv^hich was about sixty yards distant. The altitude was approximately 1050 feet. 4 These cerci are clearly of a more specialized type than the form normal in the Rliaphidophorinse, hut E. M. Walker (1922, Ann. Ent. Soc. Amer., xv, 19) suggests that the segmentation of the apical portion of the cercus in this group of species is an atavistic character. JULY, 1925] SHANNON SPHECOMYIA 43 NORTH AMERICAN SPHECOMYIA (DIPTERA, SYRPHIDiE) BY RAYMOND C. SHANNON Bureau of Entomology The species of the genus Sphecomyia are remarkable for their close resemblance to the yellow- jacket wasps, Vespa. The simi- larity of N. vittata is extraordinary, for even the antennae are greatly elongated, being quite equal to those of wasps; while pattoni and dyari, which have small antennae, have black and enlarged fore tarsi which are probably used to simulate long antennae by extending them forewards. The species are appar- ently confined to the North American Pacific Coast region, except vittata, which appears to be of holarctic distribution. Table of Species of Sphecomyia Latreille Al.

A Useful Bibliography Parshley, Howard M. Bibliography of the North American Hemiptera-Heteroptera. Smith College Fiftieth Anniversary Publi- cation. Northampton, Mass. 252 pages. Of the working tools of the systematic entomologist perhaps nothing has more value than a good bibliography. In the book cited above Dr. H. M. Parshley has given the hemipterist just such a help and has earned the sincere gratitude that will be fully accorded him. In addition to listing the works dealing with the systematic side of the subject he has wisely included papers on the biology of the group and many treating purely of the economic aspect of the subject. The names of the authors are arranged alphabetically, and under each author the titles are in chronological order, with a letter added, where necessary, so the Marks system of reference can be used if desired. In the publication of my Catalogue of the Hemiptera of America North of Mexico, the very bulk of the volume made it advisable for me to omit most references to the biologic and economic literature included in the Henshaw Bibliography of Economic Entomology and its continuations, and all bibliog- raphy except the briefest possible reference to the serials and books whose abbreviations appeared in the pages of the catalogue. Dr. Parshley’s Bibliography now supplies this omission very completely. No entomologist whose labors touch the Heteroptera at all can afford to be without this new bibliographical help. — E. P. Van Duzee. JULY, 1925 ESSIG ECONOMIC NOTES 45 ECONOMIC NOTES BY E, 0. ESSIG University of California, Berkeley, California European Earwig Although the European earwig, Forficula auricularia (Linn,), has been known to occur in certain parts of the city of Berkeley for a number of years, the first real damage to growing plants came to the attention of the writer during the month of June of the current year. The injury consisted in the destruction of flowering buds of carnations in great numbers. The earwigs ascended the plants at night and ate out the bases of the bud, in most cases destroying them completely. The presence of the earwig is being watched with considerable concern, chiefly because of the damage reported to flowers and horticultural crops in Washington and Oregon. Inasmuch as the infestation has been generally limited to areas near the Bay, where little or no gardening is done, there has been no great opportunity for serious damage. As the pest spreads, however, to the resi- dential districts, it is not unlikely that more serious injury will be reported. The question of control and extermination has been discussed with the officials of the State Department of Agriculture. An agreement was reached a year ago, whereby an inspection of the Bay district was decided upon, but lack of funds and inspec- tors caused a delay in this procedure. Extermination is prob- ably impossible, but it may be favorable to conduct a control campaign to prevent the spread of the insect throughout the State. — E. O. Essig. Beet Army-Worm on Cotton The beet army-worm, Laphygma exigua (Hubner) [L. Havi- maculata (Harvey)], occurred in great numbers on several thousands of acres of cotton in the vicinity of Bakersfield dur- ing the month of May. Very serious damage was being done to the young cotton plants, many fields of which were entirely destroyed. In addition to the beet army-worn there was also present in considerable numbers the yellow-striped army-worm., Prodenia prcefica Grote, which was particularly abundant along ditch banks and roadways. 46 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 A conference of entomologists resulted in the recommenda- tion of poison bran mash, which was first broadcasted and later drilled into the rows with seed drills. This material gave com- plete control, and the situation was cleared up almost immedi- ately. Caterpillars were fed and adult moths reared which con- formed in every way to the adults of the beet army-worm. — E. O. Essig. The Currant Moth on Peanuts Large shipments of peanuts infested with the currant moth, Ephestia elutella Hiibner, were repeatedly received at the San Francisco port from China, during the fall of 1924. The out- breaks were checked by fumigation, but litigation involving hun- dreds of thousands of dollars grew out of the shipments. This is another instance of a questionable practice causing a heavy financial loss to both the shippers and carriers. The trade gener- ally recognizes the danger of importing peanuts from the Orient during the late summer, and it is the ignoring of such well- founded customs, by those willing to take long chances, that leads to the destruction of good food and the introduction into this country of dangerous insects. — E. R. deOng. The Alder Flea Beetle The alder flea beetle, Haltica bimarginata Say, has been par- ticularly abundant and destructive in various parts of Northern California this summer. Near Middletown, California,, it de- foliated all of the alders along the streams for a distance of ten miles. — Edwin C. Van Dyke. The Monterey Cypress Bark-Beetle The Monterey cypress bark-beetle, Phlaeosinus cupressi Hopk., has heavily attacked, and practically killed, a number of Monterey cypresses on the University of California campus this last summer. Old cypress logs piled in the neighborhood enabled a large brood to develop which, with the beginning of spring, attacked the trees, those which were weakened by drought readily succumbing. This beetle is destructive only when large broods have been enabled to develop by allowing dead trees or timber to remain in the neighborhood of the living. — Edwin C. Van Dyke. THE PAN-PACIFIC ENTOMOLOGIST Published quarterly by the Pacific Coast Entomological Society in co-operation with the California Academy of Sciences E. P. Van Duzee^ Editor F. E. Blaisdell^ M. D., Treasurer The annual affiliation meeting of the Pacific Coast Ento- mological Society was held at Portland, Oregon, June 17, 1925, in connection with the meetings of the Pacific Division of the A. A. A. S. In all, more than forty entomologists were in attendance at this meeting, which proved to be an exceptionally interesting one. There was a full program of papers, crowding the morning and afternoon sessions. This meeting was followed by a two days’ meeting of the Western Division of the Ameri- can Association of Economic Entomologists, which was equally well attended, with a full and interesting program. A number of our entomologists from about the Bay region have been in the field this summer, and the net results will be a very considerable addition to our local collections. Dr. E. C. Van Dyke and E. P. Van Duzee spent the ten days before the Portland meetings, working along the Oregon coast from Wald- port to Astoria, and after the meetings Dr. Van Dyke spent another two weeks working on Mt. Hood, Oregon, and Mt. Adams, Washington, and vicinity. Mr. C. L. Fox is spending a month collecting about Pullman, Washington, and Moscow, Idaho, and other nearby places. Dr. F. E. Blaisdell went by auto to Seattle, Washington, and Vancouver Island, and Pro- fessor G. F. Ferris is spending several months cruising along the Pacific Coast of Mexico and Central America, with a small party who will make many landings for field work in geology and entomology. Dr. Ernest H. Nast spent a month col- lecting neuropteroid insects in the Sierra, and Mr. J. O. Martin made a short excursion to the Coast about Areata, California, after coleopterous material. The material taken by Mr. Van Duzee, Dr. Van Dyke, and much of that taken by Mr. Fox and others, will enrich the museum of the Cali- fornia Academy of Sciences. Mr. A. J. Basinger of Riverside, California, has presented to the entomological department of the California Academy of Sciences a collection of over 2200 insects, including a very valuable and most welcome series of Alaskan Diptera. 48 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 1 Mr. H. H. Keifer, Assistant Curator of Entomology at the California Academy of Sciences, acting as entomologist on the Academy’s Revillagigedos expedition, returned on June 12 with a fine lot of insects taken during the two months the expedi- tion was in the field. This material is now being mounted, and a fuller report on it will be included in the next number of this Journal. Mr. Walter M. Giffard of Honolulu has been a most welcome visitor at the California Academy of Sciences this summer. He and Mrs. Gififard spent two months in San Francisco, re- turning home on June 24. As is his custom when here, Mr. Giffard spent much time and effort advancing the interests of the entomological department of the Academy. Mr. F. X. Wil- liams of Honolulu has also been spending some time in San Francisco and improving the opportunity to do some work on the Hymenoptera in the collection of the Academy of Sciences. Another welcome visitor at the Academy was Professor J. B. Parker of Washington, D. C., who spent a part of July working over the Bembicidae in the Academy collection. Our local entomologists have also been favored with a brief visit by Mr. George P. Engelhardt of the Brooklyn Museum, who was making a hasty tour of the Pacific Coast region from Oregon to Arizona. The recent death of Mr. Ralph E. Dodge of Exeter, Cali- fornia, is a real loss to Western entomology. Mr. Dodge was an enthusiastic collector of the Lepidoptera, his special interest being in the moths. He had been working in con- junction with his father, Mr. E. A. Dodge of Santa Cruz, California, in building up a collection of our California moths which was rapidly becoming one of the best in the State. Our Western entomologists will feel that their branch of science has sustained a serious loss in the death of young Mr. Dodge, and will unite in extending S 5 ^mpathy to the bereaved family.

B, HERMS University of California, Berkeley The equatorial coral islands of the mid-Pacific Ocean offer much of interest to the biologist. They are for the most part unstudied biologically, being off the main routes of travel and generally more or less difficult to approach. The rather isolated group with which we are concerned in this paper consists of the following small islands : Christmas, nearest the equator. Fanning, Washington and Palmyra, extending from Lat. 1° 57' to 5° 49' North and Long. 157° 27' to 162° 11' West. With the exception of the latter, this group is governmentally a part of the Gilbert and Ellice Islands (British), and the inhabitants are mainly Gilbertese. The group was visited by the writer during the summer of 1924, and the voyage was made on a copra vessel, a small British motor schooner, under sail practically the entire dis- tance from San Francisco to Fanning Island. The trip required twenty-three days. The stay on the islands lasted about three months, very largely on Fanning, affording an unusual oppor- tunity for the study of its fauna and flora. On the return trip the Hawaiian Islands were visited, adding much to the value of the investigation because of the opportunity to compare cer- tain material in hand with collections in Honolulu, both from the Hawaiian Islands and the Society Islands, about midway between which the islands under consideration are situated, i. e., separated from these groups by distances of from about 850 to 1200 miles. Fanning Island is a typical coral atoll, consisting of a narrow rim of land hardly three- fourths of a mile wide at the most and enclosing a very beautiful lagoon, opening into the ocean at three points, thus forming in reality a circle of three narrow islands. The entire island is approximately ten and one-half miles long by five and one-half miles wide, with an external 50 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 circumference of about thirty-one miles. It comprises about 8500 acres, of which over 3200 acres are in coconuts. Wash- ington Island is about four and one-half miles in length by one and one-half miles wide, with an external circumference of about ten miles. This island encloses a shallow fresh-water lake about two miles long, with an average width of about half a mile. The highest elevation of either of these islands is not over twelve feet. Since practically all of our collecting was done on these two islands, a description of the other islands will be omitted. The total annual rainfall for Fanning Island for 1918 was slightly over 102 inches, for 1923 it was slightly over 66 inches, and for the first eight months of 1924 it was above 55 inches. The temperature ranges from about 78° F. at night to about 85° F. at noon, with very little variation throughout the year, except an occasional day when more than 90° F., or a night when 70° F. may be reached. The annual mean temperature is slightly in excess of 81° F. The humidity is seldom below 70. As might be expected, the flora of these coral islands is very meager in species, although the vegetation in some places pre- sents tropical luxuriance, notably on Washington and Palmyra Islands. The writer and an assistant collected forty-six out of the fifty-four known species of plants from this group of islands, only two small collections having been made previously. Of this total number of species, eleven have been introduced purposely, among them Cocos nucifera Linn,, Musa sapientum Linn., Artocarpiis communis Forst., Carica papaya Linn., and Hibiscus rosa-sinensis Linn. Fourteen species have been acci- dentally introduced, among them Euphorbia hirta Linn., Eu- phorbia prostrata Ait., Sida fallax Walp and V ernonia cinerea Less. According to Dean E. D. Merrill, who identified all the spe- cies collected by the writer, about twenty-nine may safely be considered as native species. Most of the bush, which in some places forms almost impenetrable thickets, consists of such native species as the Umbrella {T ournef ortia argentea Einn. f.), which may reach the height of great trees, Buka {Pisonia grandis R. Br.), also occasionally occurring as tall trees, and Nashu (Sccevola kcenigi Krause). The screw pine {Pandanus tectorius Sol.) is also a conspicuous part of the vegetation in OCTOBER, 1925] HERMS FANNING ISLANDS 51 some parts of the islands. The coconut, however, dominates all, and is never out of sight. With this rather poor flora as a basis for support, the num- ber of species of insects dependent directly or indirectl)'' on plant food is naturally not very great, but the paucity in the number of species is generally well balanced by the abundance of individuals in a given species, notably ants. The same thing may be said relative to the fauna in general. The number of species of native birds is relatively small, there being only thir- teen species on these islands (eleven sea birds, and two land birds) exclusive of migrants. The number of individuals is, however, very great and at times the sky is literally clouded with birds, almost wholly fish-eating. The noddy tern {Anous stolidus) is most numerous, and three species of boobies (Sula leucogastra, Sula dactylatra and Sula piscator) occur in abun- dance, while the booby’s arch-enemy, the man-o’-war hawk or frigate bird (Fregata minor palmerstoni is ever present. A rare species of paraquet (Vinus kuhlii) , a most exquisite creature is rapidly growing less in numbers, though still fairly abundant. The very beautiful tropic bird or bo’s’n bird (two species, Phcethon lepturus and PhcEthon rubricaiida) is fairly common in this region. The ground almost everywhere is full of crab holes, and as one approaches these, the ludicrous omnivorous land crab (Car- disoma obesum) sidles away and disappears in its burrow. Hermit crabs (Ccrnobita rugosa) are exceedingly abundant and pestiferous, apparently attacking almost anything. The so-called coconut crab (Birgus latro) , a large and powerful species, is rapidly becoming extinct, but may still be seen climbing coconut trees at night, hiding in holes in the ground and cavities of trees during the day. Two species each of gheckos and skinks, usually measuring not over five or six inches in length, are remarkably abundant, and their rather large, white eggs are frequently encountered in pockets in the rough trunks of the coconut trees and elsewhere. Rats (Rpimys alexandrinus) are very numerous and a serious pest to the coconut industry. During the practically three months’ stay on these islands much time was given to the study of coconut pests, particularly the Tahiti coconut weevil (Diocalandra taitensis Guerin). Rela- 52 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 tively little time remained for much else, however, spare hours were diligently spent in making collections. Although many insects were collected and safely brought to Berkeley in pill- boxes, the total number of species taken is quite disappointingly small, namely, only about ninety. These ninety species are distributed somewhat as follows, with probable corrections after all the material has been care- fully checked up: Coleoptera, 31 species, included in the following families: Staphylinidse (2), Hydrophilidas (1), Cleridae, (1), Nidituli- dae (1), Cucujidae (2), Dermestidae (1), Cryptophagidae (1), Ostomidae (1), Coccinellidae (1), Elateridae (3), Odomeridae (4), Tenebrionidae (3), Scarabaeidae (1), Cerambycidae (1), Anthribidae (1), Curculionidae (5), Scolytidae (2). Diptera, 12 species, included in the following families : Culi- cidas (2), Tipulidae (2), Dolichopodidae (2), Ortalidae (1), Sarcophagidae (1), Muscidae (1), Calliphoridae (2), Hippo- boscidae (1). Hymenoptera, 10 species in the following families : Apidae (1), Formicidae (7), Evaniidae (1), Chalcididae (1). Hemiptera, 8 species in the following families : Pentatomidae (1), Cydnidae (1), Miridae (1), Nabidae (1), Coccidae (4). Orthoptera, 8 species in the following families : Blattidae (5), Tettigoniidae (1), Gryllidae (1), Forficulidae (1). Lepidoptera, 7 species in the following families: Noctuidae (4), Sphingidae (1), Nymphalidae (2). Isoptera, 2 species. Mallophaga, 3 species. Anoplura, 1 species. Odonata, 3 species. Thysanura, 2 species. BUTTERFLIES Although one specimen of the milkweed butterfly {Danaus archippus) , taken on Fanning Island, appears in my collection, the specimen having been given to my assistant, Mr. Kirby, by a native, none was actually seen by either of us, and the pres- ence of this one specimen is rather puzzling. On the other hand, the beautiful Hypolimnas bolina Linn, occurs rather abundantly, though restricted in range, in certain localities on Fanning. I took all three color phases during my stay on this island. So OCTOBER, 1925] HERMS FANNING ISLANDS 53 far as I know, the sole food plant of the larvae on this island is Sida fallax Walp, an accidentally introduced weed called “kaura” by the native Gilbertese. The natives were greatly impressed by the fact that the writer reared in his room the beautiful “tebuba” (butterfly) from the ugly ‘‘worm” which feeds on the “kaura.” Although I do not kpow how long the larval period is, the pupal period is quite short, for example, two caterpillars pupated Sunday, June 8 (1924), between 8:45 a. m. and 9 a. m., and emerged early Monday morning, June 16, giving a pupal period of eight days. The type locality for this species is the Indo-Malayan region. It occurs in Madagascar and western China. MOSQUITOES Mosquitoes (Aedes) were very abundant and annoying on Washington Island where they breed primarily in the rain receptacles, from which the water is taken for drinking and general domestic purposes. The natives dig shallow water holes, “temanipa,” in which mosquitoes (Culex) breed in enormous numbers, particularly on Fanning, where these water holes are of frequent occurrence. HEAD LICE Head lice {Pediculus capitis) are very abundant among the native Gilbertese. These lice are distinctly brownish black in color, as may be seen from the specimens taken from natives on Fanning Island. The lice are considered a delicacy by the natives. If it were not so disgusting, I might go into consider- able detail to describe the instances in which I witnessed the evidently joyous tete-a-tetes in which this form of delousing was in progress. TERMITES Two species of termites were taken on Fanning Island, namely, Kalotermes immigrans Snyder, a Hawaiian species, and Cryptotermes hermsi sp. nov. (named by Kirby ^). Only one nest of the former was found in which these insects were tunneling in the hard wood of a prostrate log of Tournefortia, the Umbrella tree. The second species was common and abun- dant in decayed logs and stumps of coconut and Tournefortia. Cryptotermes hermsi Kirby is a close relative of the Oriental 1 Kirby, Jr., Harold, 1925.

T-welve figures in text. 54 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 termites and is interesting because of its occurrence on Fan- ning and its absence both from the Hawaiian Islands and Aus- tralia, with which Fanning Island has maritime contact. This species is said to differ markedly from Cryptotermes primus Hill of Australia, and even more decidedly from Cryptotermes piceatus Snyder of the Hawaiian Islands. It is closely related to Cryptotermes kotoensis Oshima, an Oriental species. BLISTERING BEETLES Shortly after boarding the vessel which was to take me to Fanning Island, I was told about a beetle which blisters on contact, and is very common. Not long after my arrival I learned from experience that this was the case. Myriads of individuals of two species of Sessinia swarm about the newly opened male flowers of the coconut, feeding on pollen. These two species are Sessinia collaris (Shp.) and Sessinia decolor Fairm., both of which are locally called coconut beetles. Both of these species were readily attracted by a strong electric light, which was led from the ship to the land for the purpose of collecting insects. Sessinia decolor certainly causes severe blis- tering if, for example, it is slapped when crawling on the forearm while collecting specimens. A specimen came in con- tact with my forearm on the evening of May 20 (1924) and was rather lightly brushed away, but the following day a large blister appeared, measuring about three-quarters of an inch in length by one-quarter inch in breadth, considerably elevated and filled with clear liquid. I opened the blister and applied iodine. The blister did not cause any appreciable pain. A more detailed study of the species of insects taken on these islands is in progress and will be published shortly, together with observations concerning their geographical distribution. NOTE ON OPUNTIA INSECTS Doctor H. G. Dyar has just indicated the identity of “Meli- tara sp.,” page 5, Vol H, this journal. For this form the name, holla Zeller, is available, but Doctor Dyar considers it advisable to treat it as a variety of the Florida prodenialis Walker. The Florida form is, then, Melitara prodenialis prodenialis Walker, while the Texan “Melitara sp.” is Melitara prodenialis hollii Zeller. — J. C. Hamlin. OCTOBER, 1925] CHAMBERLIN MYRIOPODA 55 NOTES ON SOME CENTIPEDS AND MILLIPEDS FROM UTAH BY RALPH V.

Last three pairs of 56 THE PAN-PACIFIC ENTOMOLOGIST [VOL. II, NO. 2 coxae dorsally armed; only the last coxae laterally armed. In the male the anal legs have the last joint furrowed along the mesal side, as in the next species; the fourth joint is also similarly modified, bearing a dorsal lobe at distal end, its mesal surface broadly fur- rowed, also furrowed along ectal surface above. Length, 12 mm. Locality. Logan Canyon, Cache County, Utah. One male and two smaller females. Nearly related to L. francisccE, but differing decidedly in color, in being broader behind and thus more attenuated cepha- lad, in having only the last coxae laterally armed, in having the ventral spines of anal legs, 0, 1, 3, 2, 0 instead of 0, 1, 3, 2, 1, etc. Lophobius franciscae Chamberlin, sp. nov. Allied to L. collium (Chamberlin). It differs from that species obviously, in being reddish or chestnut instead of yellow or orange. It differs from that species also, in having the ventral spines of the anal legs normally 0, 1, 3, 2, 1, instead of 0, 1, 3, 2, 0, though the latter formula may occasionally hold; also in having only the last two instead of the last three coxae laterally armed. Antennae nor- mally with twenty articles, but varying up to twenty-six, the num- ber tending to differ in such cases on the two sides. Basal spines of female gonopods, 2 2 or 3 -b 3. In the anal legs of both sexes the last article is furrowed along the mesal side. In the anal leg of male the fourth article is conspicuously thickened and is broadly furrowed or excavated on mesal side, the excavation limited above by a ridge-like margin somewhat as in collium ; at the distal end, above a conspicuous process or lobe. Length, 13 mm. Locality. Cedar City, Utah. May, 1924. Named for Mrs. Frances (Brown) Chamberlin. PoKABius UTAHENSis (Chamberlin) Localities. Utah: Bear Lake. Many females. Also Logan Canyon. Many specimens, both males and females, but the females much predominating. A form abundant under damp leaves in shaded places along canyon streams in the northern part of the State. Lithobius forficatus Linne Locality. Utah : San Pete County, Fairview. Many speci- mens. This introduced species has become common about settle- ments in the more northern part of the State. Gosibius arizonensis Chamberlin Localities. Parowan and Cedar Canyons. May. Only males secured. The specimens agree closely with Arizona individuals, though OCTOBER, 1925] CHAMBERLIN MYRIOPODA 57 apparently somewhat smaller. The spines of the anal legs in one adult male 0, 1, 3, 3, 1 instead of 0, 1, 3, 2, 1, Ethopolys parowanus Chamberlin, sp. nov. Related to E. bipunctatus (Wood), occurring in northern Utah and in Nevada, in having none of the dorsal plates produced. It is a smaller form with shorter antennje. It differs in having only one tooth ectad of the prosternal spine, the usual formula being from 1 — 4+4 — 1 to 1 — 6+6 — 1. It is also characterized by having the claw of the female gonopods entire, or essentially so, instead of tripartite; basal spines in adults 3, 3, more rarely 2 + 3 or 2 + 2. Ventral spines of anal legs, 1, 1, 3, 2, 0 or 1, 1, 3, 2, 1, the claw single. Ventral spines of penult legs, 1, 1, 3, 3, 2; dorsal spines, 1, 0, 3, 1, 1; claws, three. Length, 21 mm. Localities. Utah: Parowan; also Cedar City. April and May. Many specimens. Bothropolys permundus Chamberlin Localities. Utah: Mill Creek Canyon, Logan Canyon, Bear Lake. Many specimens of this species were taken in each of these localities. It is one of the most common chilopods of the Wah- satch Mountains. Kethops leioceps Chamberlin, sp. nov. Differs from K. utahensis, the genotype, in wholly lacking both the paired and the unpaired sulci on cephalic plate. First dorsal plate similar, in having a cervical sulcus and paired sulci that branch and together form a W behind the cervical sulcus. Last dorsal plate wider at caudal than at anterior end, its caudal margin convexly bowed out in the middle, not emarginate. Last ventral plate strongly narrowed caudad. Coxopleurae with caudal process short; scattered short spines. The anal legs in general form as in utahensis; the joints broad but not furrowed ventrally; femur with a median ven- tral area free from spines, toward mesal side of ventral surface a series of four stout spines or teeth. Tibia also with a series of four ventral teeth. Metatarsus with a ventral series of close-set teeth, not with an edge excised at middle as in utahensis. Length, 24 mm. Locality. Utah: Mill Creek Canyon. One specimen. Theatops posticus (Say) Locality. Utah: Washington County. May. One specimen. This species is very common in the Southeastern States, but has not been known previously from the West. Otocryptops sexspinosus (Say) Locality. Utah: Zion National Park. May. One young specimen. 58 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 There is little doubt that the specimen is correctly referred, although the margiiiation of the head is obscure. The species is common, both in the Eastern and Southeastern States and on the Pacific Coast. SCOLOPENDRA POLYMORPHA Wood Localities. Utah : Washington, St. George and Zion National Park. April and May, 1924. This species ranges northward in the State as far as Salt Lake City. The Utah specimens are dwarfed, in comparison with those found in Arizona and southern California. Scolopendra utahana Chamberlin, sp. nov. Head without longitudinal sulci, smooth and shining, obscurely finely punctate. Antennas short; articles twenty, of which only the first four are nearly glabrous. First dorsal plate with a strongly marked cervical sulcus like that of S. polymorpha; without longitu- dinal sulci. Last dorsal plate short and broad; with a fine median longitudinal impressed line. Dental plates of prosternum each with four teeth, of which the three innermost are united at base. Anal legs short; femur short and thick with about fifteen seriate spines ventrally, none on mesal surface except the series of five teeth along dorso-mesal edge; process at dorso-distal corner bearing only two teeth, which are long. Length, 45 mm. Locality. Utah: Zion National Park. May. Resembles S. polymorpha Wood, but readily distinguished, in having only the first four articles of antennae glabrous instead of eight or more, in having the distal process of femora of anal legs with only two spines, and in having the mesal surface of femora free from spines. Nyctunguis molinor Chamberlin, sp. nov. Body yellow, near orange, the middle and posterior segments also of an orange or red tinge. The cephalic plate longer than wide, longer than in liber colens, a species it resembles; widest in front of middle from where more strongly narrowed caudad than cephalad; anterior margin forming an obtuse angle. Prebasal plate exposed. All joints of prehensors unarmed; claws when closed failing con- siderably of attaining the front margin of head. Labrum wide, some- what as in libercolens, but the median arc deeper and shorter, the teeth proportionately larger and fewer, t 3 ^pically ten in number. Ven- tral pores present on anterior plates, forming a small circular area on each plate. Last ventral plate broadly trapeziform, not strongly narrowed caudad. The coxal pores two on each side, homogenous, the anterior one covered by last ventral plate, the posterior one partly covered; posterior gland much larger than the anterior one. Pairs of legs, 47 (6), 49 (2). Length, 17 mm. OCTOBER, 1925] CHAMBERLIN MYRIOPODA 59 Locality. Utah : At mouth o£ Mill Creek Canyon. One male and one female. May. Geophilus shoshoneus Chamberlin, sp. nov. A species resembling the Eastern G. mordax, but a much smaller form, easily distinguished in not having the prebasal plate exposed, the cephalic plate extending well over it. Claws of prehensors, when closed, attaining anterior margin of head. Prosternum and joints of prehensors unarmed. Chitinous lines present on prosternum, fine. Antennae short. Ventral pores of sternites numerous, forming a transverse band broadest at middle in front of posterior margin. Last ventral plate wide, the posterior margin a little indented at middle. Coxal pores four or five on each side close to margin of plate, with no isolated single pore such as is characteristic of mordax. Pairs of legs, 55-57. Length, 20 mm. Locality. Utah : Logan Canyon and on the divide between this canyon and Bear Lake Valley. Two specimens. Geophilus rubens Say Locality. Utah: Washington County. Three specimens. May. A species also met with frequently in Arizona. The Utah specimens agree with those from Arizona, in usually lacking a geminate black stripe along dorsum. Linot^nia chionophila (Wood) ?

Utah: Parowan, one male; Trout Creek, two specimens ; Bear Lake, one male ; Logan, many specimens. All specimens examined have thirty-nine or forty-one pairs of legs, excepting one specimen from Logan Canyon, which seems also variant in other respects. Gnathomerium xenoporus (Chamberlin) Localities. Utah : Parowan, Cedar City, Mill Creek Canyon, Logan Canyon. Many specimens. This is evidently the most common geophilid in the canyons of Utah, where it is often abundant in leaf mold along streams. It occurs also in Colorado and New Mexico. 60 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 DIPLOPODA Parajulus canadensis (Newport) Locality, Utah: Mill Creek Canyon, April. Two males. This is a common species in eastern Canada and adjacent parts of the United States, but it has not previously been found west of the Rocky Mountains. Parajulus tiganus Chamberlin Localities. Utah: Mill Creek Canyon, Provo Canyon, Logan Canyon, and Bear Lake. Many specimens. This is probably the commonest diplopod in the State. It has not been found as far south as Cedar City, however, where it seems to be largely replaced by P. paiutus, a new species here described. Parajulus paiutus Chamberlin, sp. nov. This is a smaller form than P. tiganus. The color is brownish with a row of black spots along each side, corresponding to the repug- natorial glands, and a median dorsal longitudinal black line. A gemi- nate lighter band across dorsum between the lateral spots on each segment. Last segment darker, blackish. Legs yellow. Antennae blackish. Distocaudal corner of cardo of mandible in male conspicu- ously produced, not excavated, the angle narrowly rounded. First legs thickened as usual, but less so than in tiganus. Gonopods of male of very different form from those of tiganus, being more like those of P. nigrans. Both lobes of anterior pair short; posterior lobe glabrous, narrower than anterior, a little bent forward distally. Pos- terior gonopods narrowed distally, a little curved caudad distally, the seminiferous duct opening at the caudally directed tip, much as in nigrans. Number of segments, 54. Length, male, 27 mm. Localities. Utah: Parowan, nine specimens, in part not adult, taken in canyon above the town; Cedar City, four speci- mens also taken in canyon above town; and Zion National Park, one female. Tylobolus utahensis Chamberlin, sp. nov. A form more slender than usual in the genus, the length being ten times the thickness. Brown in color, the metazonites darker brown, with a tendency toward chestnut, the ectal caudal border paler. Repugnatorial glands showing as blackish spots on the sides, especially in the posterior region. Legs brown. Collum much nar- rowed at each end. Coxse of third legs in male with the usual uncate processes, the immediately following coxae also produced. Median plate of anterior gonopods of male distally pointed, much exceeded by the coxal plates, which are contiguous at middle and each of which at its mesal corner is produced ventrad. The telopodite is OCTOBER, 1925] CHAMBERLIN MYRIOPODA 61 somewhat enlarged at distal (mesal) end, but is only a little bent caudad at the end, not uncate. In the posterior gonopods the ter- minal hook or blade is smooth; at base of hook in the angle is a stout angular projection or tooth; the bent portion proximad of blade finely scabrous. Number of segments, 51-53. Length, 54 mm.; width, 5.2 mm. Female allotype, 7 mm. thick. Locality. Utah: Zion National Park. Five adult males, two adult females, and two young specimens, Nannole uta (Chamberlin) Locality, Utah : Little Willow Canyon. Diploiulus luscus (Meinert) Locality. Utah: Mill Creek. Many specimens were taken on cultivated ground below mouth of the canyon. The species is now not uncommon in other places near Salt Lake City. A native of Europe, it is frequently brought to this country in soil about the roots of plants from Holland and other European countries. It long ago became established in the Eastern States and has now extended its range to California. It occurs only in settled or cultivated districts. Scytonotus orthodox Chamberlin, sp. nov. General color brown, in part of a weakly reddish tinge. Legs yel- low. The second tergite bearing four well-developed series of tuber- cles; the anterior corners of keels produced along ends of collum, acute; lateral crenuations weak, with a translucent margin. In ter- gites of the middle region of body a transverse sulcus distinctly marked, behind the sulcus with three or in part four rows of well- developed tubercles, but in front of the sulcus the tubercles are low and are in part obliterated. Prozonites nearly smooth, the granules numerous, but very small or obscure. Distinguishable in structure of the male gonopods; the two blades equal in length, rather slender, the posterior one bidentate apically on caudal side, the teeth acute; anterior branch apically acute, with caudal margin straight and an- terior convex. Gonopods very similar to those of S. amandus; but in the latter the branches are unequal, the dentate one being obvi- ously shorter and its teeth closer together. Localities. Utah : Logan Canyon, five adult males and three partly grown specimens; Bear Lake, about eighteen specimens, male and female, with some immature. The young specimens do not show any reduction of the tuber- cles in front of the suture. Spirostrephon utorum Chamberlin, sp. nov. The color is light yellowish brown without distinct markings. Be- 62 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 tween the median keel and the thickened porigerous keel on each side of a typical segment there are three major setigerous keels, with a much lower non-setigerous keel between each two major ones; the porigerous keel much higher than these more mesal keels and its margin conspicuously convex in profile instead of nearly straight; below each porigerous keel two somewhat similarly high setigerous keels with a low, non-setigerous keel between these and one above the upper one; below on the side other non-setigerous keels which become lower in going ventrad. The major keels in profile are seen to be serrate or dentate. Number of segments, sixty. Locality. Utah: Green River. One male. R. V. Chamber- lin, Jr., collection 1920. Apparently related to S. mutans of Southern California; but aside from more technical structural differences, it is conspicu- ously distinct in coloration and in the greater number of seg- ments to the body. Tingupa utahensis australis Chamberlin, subsp. nov. In the absence of males a wholly certain determination of the position of this form is not possible. It agrees in general structure, the form and sculpturing of the tergites, etc., with typical utahensis from the northern part of the State, but it is a larger and more robust form. Color brown, the caudal border of metazonites paler, as is the prozonite in the constricting furrow adjacent to metazonite. Sixth and seventh articles of antennse equal in length, the fifth much longer and distally slightly thicker than the sixth. The eye-patch is differently shaped, being trapeziform rather than triangular, with the dorsal side, rather than that along caudal margin, longest; ocelli in the holotype in six or seven vertical series instead of in four; e. g., beginning with most caudal row, 5, 4, 3, 2, 2, 1; and in four or five transverse, somewhat curving, series, e. g., beginning at top, 1, 7, 5, 3, 1. Length, about 9 mm. Locality. Cedar City, Utah. One female taken in the can- yon. May. Underwoodia tida Chamberlin, sp. nov. A much smaller form than hespera, differing superficially also in being distinctly paler in color on the sides below level of pores than on dorsum; finely mottled. Legs dusky yellow. Antennae of same color as legs. Head dark above in frontal region with numerous fine, pale dots, clypeus yellow. Sixth joint of anteniiEe decidedly thicker and longer than the seventh. Ocelli in a triangular patch with apex mesad; thirteen in number, arranged in three or four oblique series, e. g., 6, 5, 2 or 1, 5, 5, 2. Collum not distinctly margined below. Length, 6 mm. Locality. Utah: Logan Canyon. OCTOBER, 1925] CHAMBERLIN MYRIOPODA 63 Underwoodia hespera Chamberlin, sp. nov. The body in general is brown, with the nietazonites darker, light spots on each side indistinct. Head dark, black, or nearly so. Legs dusky over yellow or light brown, the antennae blackish. In the antennae the sixth article is narrower than the fifth and is obviously and considerably longer than the seventh instead of being equal to it, as is the rule in species of Cleidogona. Ocelli distinct; eighteen, in five somewhat irregular longitudinal series, as follows: 1, 2, 4, 5, 6; the patch triangular in outline, with the apex mesad in position. Body strongly narrowed anteriorly. Collum acutely narrowed down each side, margined anteriorly on each side, otherwise smooth. Seg- ments in general smooth, not striate above, under lens seen to be evenly marked with areas defined by fine lines, the areas mostly from quadrate to oblong in form. Length, 8 mm. Locality. Utah: Mill Creek Canyon. One female. POLYDESMUS MONILICORNIS Koch Locality. Mill Creek. One immature specimen, apparently this form, which is common in the Eastern States and Canada.

BENJAMIN Decatur, Illinois Macrotheca lecerfialis Barnes and Benjamin, sp. nov. Ground color white; fore wing with a few scattered black scales; t. a. line black, single, waved from costa to inner margin; orbicular represented by a few black scales; reniform obsolete; t. p. line single, black, nearly erect, little waved, a trace of a blackish s. t. suffusion subapically; a terminal row of dots; fringe white, with a few black scales; hind wing only slightly darker than fore wing; discal spot and median shade obsolete; an obscure terminal line; fringe luteous- white basally, distally white. Expanse, 9-11 mm. Allied to hilinealis and flexinealis. Lack of reniform will easily sort it from the latter, while its much paler coloring and more erect t. p. line will easily distinguish it from the former. Type locality : Dixieland, Imperial County, California. Number and sexes of types : Holotype 6 , 15-30 April, 1922 ; allotype 2, 1-15 May, 1922; 8 6 paratypes, 15-30 April, 1922.

In the original description of the genus and species the antennae of the female is described as being simple. A series of females before us, including the type 2 and four 2 ‘‘Cotypes,” proves this to be incorrect. The antennae are decid- edly strongly lamellate, as that term is applied in Lepidoptera : viz., dentate. The type series bore no dates. Specimens have been received from the Baboquivari Mountains, Pima County, Arizona, April, May, June, September, and October; and from Clark County, Nevada, June. OCTOBER, 1925] VAN DYKE HARPALIN^ 65 NEW SPECIES OF CARABIDPE IN THE SUBFAMILY HARPALINiE, CHIEFLY FROM WESTERN NORTH AMERICA BY EDWIN C. VAN DYKE University of California, Berkeley, California Bembidium ccerulescens Van Dyke, new species Form moderately elongate, gracefully proportioned, slightly con- vex, shining, nigropiceous with a bluish luster above, especially on head and prothorax, the antennae, palpi, tibiae, and tarsi brownish. Head scarcely narrower than the prothorax at apex, alutaceous, e 3 '^es moderately prominent, antennae slender, about one-half length of body, frontal grooves single, straight and shallow, mandibles promi- nent. Prothorax as wide as long, three-fourths as wide as elytra at base, narrower at base than apex; apex feebly emarginate; sides with the margins distinctly reflexed, moderately arcuate in front, grad- ually narrowed and sinuate posteriorly; hind angles slightly obtuse and not carinate; disc alutaceous with median longitudinal groove well impressed and abbreviated in front; anterior transverse impres- sion well defined; area in front of it with a number of longitudinal rugae; basal impressions broad, deep, indistinctly bistriate, the entire basal area rugose. Elytra elliptical, three-fifths as broad as long; humeri distinctly rounded; sides slightly arcuate anteriorly, more decidedly so posteriorly and but slightly sinuate in front of apex; disc finely striate, the striae entire and with very vague punctures anteriorlj'-, the outer ones less deeply impressed, the fifth terminat- ing in a deep groove; third stria with first dorsal puncture slightly in front of the middle and second about one-fourth distant from apex; eighth stria at border of marginal groove, the intervals flat. Length, 7 mm.; breadth, 3 mm. Holotype, male (No. 1818, Mus. Calif. Acad. Sci.), in my collection, kindly presented to me by Mr. Merton C. Lane, who secured it near the margin of the stream in Niles Canon, Ala- meda County, California, December 27, 1919. Two paratypes captured at the same time are in Mr. Lane’s collection. This very graceful species looks not unlike a small specimen of Platynus funehris Lee. According to the arrangement of Roland Hayward,’- it would have to be placed in his Group VH (planatum) , and close to funerenm Lee., though it is very much larger, almost as large, in fact, as planatum Lee. It resembles nigrocoeruleum Hyd. only in color. It is also a more elegantly formed insect than any other in the group. 1 “On the Species of Bembidium of America North of Mexico,” by Roland Hayward. Trans. Am. IDnt. Soc., Vol. XXIV (1897), pp. 32-143. 66 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 Bembidium utahensis Van Dyke, new species Form elongate, depressed, color dark rufous. Head large, but slightly narrower than the prothorax; eyes small and much flattened, hardly extending beyond the sides of the head; antennas stout, reach- ing but two segments beyond the humeri; frontal impressions single, shallow and lunate; mandibles prominent, porrect; palpi rufocasta- neous, the terminal joint of the maxillary palpi at least twice as long as the similar joint in Bembidium laticeps Lee. Prothorax almost a third broader than long, narrower than elytra at humeri; apex feebly emarginate; base just perceptibly arcuate; sides moderately arcuate in front, sinuate posteriorly and parallel for a short distance in front of base; hind angles right; lateral margin narrow; disc barely con- vex; median longitudinal groove well impressed, especially pos- teriorly, and almost completely; anterior and posterior transverse impressions obsolete; basal impressions deep, with double striae vaguely defined, most of the basal area somewhat rugose. Elytra elliptical, somewhat more than a third longer than broad; humeri rounded but with prominent basal ridge running obliquely inwards, the margin fine; disc somewhat flattened, all striae present, well impressed near suture, less defined laterally and apically, and finely punctate; third stria with two dorsal punctures, the first slightly in front of the middle, the second somewhat more than a fourth of the distance from apex; eighth stria in marginal groove. Length, 4.5 mm.; breadth, 2 mm. Holotype, male (No. 1819, Mus. Calif. Acad. Sci.), in my collection, secured near Salt Lake City, Utah, by Professor R. P. Chamberlin, and kindly presented to me by Dr. William M. Mann. A second specimen was in the collection of Dr. Mann. This beetle has its closest relative in Bembidium laticeps Lee. and belongs with that and Bembidium puritanum Hyd. It dif- fers from the former by being larger with the prothorax more elongate and less broad, the elytra also more elongate, with all of the striae well defined and finely punctured, whereas in the other the striae are but vaguely defined. It is interesting to find the third member of this small group near Great Salt Lake, laticeps being found near the seashore in southern California and puritanum in Massachusetts. Trechus ruficollis Van Dyke, new species Body rather stout and somewhat convex, shining, rufopiceous; head and prothorax rufous; antennae, palpi, legs and epipleurae cas- taneous. Head more than three-fourths as wide as prothorax; eyes moderately prominent; frontal sulci long, deep and semi-circular; antennae moderately slender, segments definitely broadened out- OCTOBER, 1925] VAN DYKE HARPALINyE 67 wardly, extending to second fourth of elytra. Prothorax small, not quite twice as wide as long; sides moderately arcuate anteriorly, sinuate posteriorly and straight and parallel near base; hind angles prominent and right, the lateral margin moderately reflexed; disc with the median longitudinal groove finely impressed, the anterior transverse impression vague, the posterior pronounced even at middle, the basal impressions moderately deep and diffuse. Elytra oval, somewhat truncate at base, almost twice as wide as prothorax and two-thirds as wide as long; disc with the three inner striae very fine, though observable and complete and with slight indications of a fourth stria; third stria with three foveae, the first one-fifth dis- tant from base, the second at about the middle, and the third close to the apex. Length, 3.5 mm.; breadth, 1.75 mm. Holotype and three paratypes, bearing the label, Lawrence, Massachusetts, found among a series of unplaced specimens in the entomological collection of Cornell University. They were part of the Crew collection. The holotype and one paratype will be deposited at Cornell University, and the two remaining paratypes will remain with me. This species belongs in the series with arisonce Casey, hydro- picus Horn, ovipennis Mots., and pomonce Fall, agreeing with all in the general form and degree of smoothness. It, however, differs from all by having shorter and heavier antennae, the pro^ thorax more decidedly sinuate posteriorly, approached slightly in this regard by ai'isonce Casey, the hind angles more promi- nent, and by being bicolored, the rufous prothorax, in all speci- mens seen, strongly contrasting with the piceous elytra. It is possible that, in spite of the definite locality label, these speci- mens may have come from some other locality, for it seems strange that such a well-marked species should occur in Massa- chusetts and remain unknown so long. It does not seem to agree with any of the European species and, as stated, bears a strong resemblance to certain American species. Patroboidea Van Dyke, new genus Body very elongate, parallel and flattened. Head large, elongate, gense prominent and long, reaching from the posterior margin of the eyes to the antenna, head constricted posteriorly, with deep and broad frontal grooves and two supra-orbital seta, one rather incon- spicuous. Antenna long, reaching to posterior third of body, moder- ately stout, arising under a feeble frontal ridge; first and second seg- ments glabrous, the following fairly pilose; first robust, second small and transverse, third long, as long as the two following united and about five times as long as the second; segments three to six of 68 THE PAN-PACIFIC ENTOMOLOGIST [VOL. II, NO. 2 about equal length and breadth, seven to ten also of about equal length and breadth, but somewhat shorter than the preceding, the eleventh about as long as the third. Eyes poorly developed, pro- jecting but little beyond sides of head, well removed from the mouth. Clypeus well developed, transversely depressed in front and with lateral setae. Labrum short, broadly shallowly eniarginate and pluri- setose in front. Mandibles prominent, prognathous, feebly arcuate, acute and curved at tip, with setigerous puncture in scrobe. Maxil- lae slender, acute at tip, ciliate with stiff hairs on inner side, the outer lobe biarticulate; palpi rather long, the terminal segment grad- ually tapering to apex, slightly longer than preceding, the point subacute; penultimate not hairy. Submentum broad, its basal suture distinct, deeply emarginate and with broad truncate lobe at middle; epilobes dentiform; ligula moderately prominent, rounded and bise- tose at apex; paraglossse broad, rounded at apex and very little longer than the ligula; palpi of moderate length, the terminal seg- ment conical, somewhat blunt at apex and slightly longer than preceding segment. Prothorax flattened, with side margin narrow and with setigerous punctures near the front and at hind angles. Body not pedunculate, scutellum distinct. Elytra flattened, elongated, more or less ellipti- cal, not margined at base; sides narrowly inflexed; margin pos- teriorly entire and without internal plica; disc with nine complete striae, counting the marginal; first and second and the third and fourth united at the apex; third with three dorsal punctures, the first one-fourth distant from base, the second at about the middle, and the third one-fourth distant from apex. Prosternum moderately sep- arating the coxae and declivous at apex. Mesosternum narrowly separating the coxae. Metasternum long, the epimeron short, the posterior coxae contiguous. Anterior tibia of the male somewhat angulated, the emargination deep and about one-third distant from apex; tarsi slightly dilated and squamose beneath. Genotype, Patroboidea rufa Van Dyke, new species. This genus, without doubt, belongs in the tribe Pogonini, as defined by Horn,^ and in the first of his groups, the group Pogoni. It belongs near the genus Patrobus, and in general has much the appearance of the flatter members of that genus, those classed as Platidius by Chaudoir, but it is much smaller than any of the species included within that, and in fact looks much like the European Thalassophilus longicornis Sturm. With this last, it agrees as regards general size, shape and color, small eyes, and heavy and long antennae, but it differs in lacking the basal striae of the elytra and in having a very small second 2 “On the genera of Carabid^, with special reference to the fauna of Boreal America,” by George H.

From Pogonus, it differs pri- marily in having the genae well developed and elongated, the constriction of the head, therefore, not just back of the eyes but far removed, in having the eyes poorly developed and the palpi, both maxillary and labial, quite long and slender and sub- acute at apex, in contrast to the truncated palpi of the other. Patroboidea rufa Van Dyke, new species Elongate, quite parallel, much flattened, rufous, head somewhat darkened. Head elongated, somewhat elliptical, smooth, impunctate; frontal impressions deep, straight, extending back as far as eyes; mandibles long, porrect, and but little curved except at apex; eyes small, projecting but little beyond sides of head; antennge rather stout, long, extending to beyond middle of elytra. Prothorax slightly broader than long and about as long as head, including mandibles; base narrower than apex; apex slightly emarginate; base truncate; sides moderately arcuate in front, sinuate posteriorly, the hind angles prominent and right-angled; disc flattened, smooth, with median longitudinal groove deep and complete, anterior transverse impres- sion vague, the posterior mainly indicated by a series of well marked punctures, the basal impressions deep and broad posteriorly. Elytra slightly longer than head and prothorax combined, about one-third wider than prothorax, base emarginate, the humeri rounded; sides almost parallel, but slightly arcuate; disc flattened; striae well de- fined, complete and with but a few indistinct punctures near base; scutellar strise fine. Body beneath smooth and shining. Length, 5.5 mm.; breadth, 2.25 mm. Holotype, male (No. 1820, Mus. Calif. Acad.

It was described from Sitka, but is a common species on the islands off the coast of southeastern Alaska and on Orcus Island in Puget Sound, as well as on the Selkirk Mountains of British Columbia and the Cascades of Washington and Oregon, at least as far south as Mt. Jefferson. In the northern Cascades it lives as does Pteros- tichus protractus Lee. in the Sierras, in the woods under old logs. Structurally, it is about midway between castaneus, which is generally to be found in the same environment with it, and protractus, and in fact if found in the Sierras would no doubt be taken for a small specimen of the latter. It is most decidedly not the same as castaneus, as stated by LeConte,® nor synony- mous with scutellaris, as given by Horn.® Pterostichus scutel- laris Lee. is nothing more than a fully pigmented or melanotic offshoot of amethystinus. This last, a common species of the dense forests of the Pacific Northwest, extends into California and along the coast only so far as northern Sonoma County, where scutellaris takes its place, and continues on to Monterey County. There seems to be a distinct cleavage between the two species, and the fact that in ancient times a gulf existed at about the place where one replaces the other might account for this. Pterostichus nigrocaeruleus Van Dyke, new species Moderately elongate, somewhat flattened, gracefully proportioned, head and pronotum shining black, elytra violet to bluish black, an- tennae, legs and under surface piceous to rufopiceous. Head rather large, almost two-thirds breadth of prothorax, very smooth and shin- ing, frontal grooves long and well impressed; the mandibles promi- nent and noticeably hooked at apex; eyes moderately prominent; antennae slender, extending several segments behind the base of the prothorax. Prothorax slightly wider than long, anterior angles prominent, sides broadly arcuate anteriorly, sinuate posteriorly, hind angles right-angled; lateral margin broad and reflexed; disc slightly convex, very smooth and shining, median longitudinal groove deep, the anterior and posterior transverse impressions distinct; basal im- pressions single, long and deep, the basal area external to these flattened, not margined, and slightly reflexed in a wing-like manner.

Legs slender, first three segments of posterior tarsi deeply grooved on outer side, posterior trochanters over one-third length of femora. Apex of prosternum not evidently margined. Beneath moderately smooth and shining. Length, 12 mm.; breadth, 4.5 mm. Holotype, male (No. 1821), allotype, female (No. 1822, Mus. Calif, Acad. Sci.), and several paratypes, in my collec- tion, captured by myself along the sides of a mountain stream back of Port Angeles, Washington, May 26, 1907. Paratypes will be deposited in the United States National Museum. In addition, I have used for comparison over fifty more specimens in my collection, which I collected at the following localities : The Forks, Clallam County, Washington; Marys Peak, Ben- ton County, Marshfield, Olney near Astoria, and Waldport, Oregon; and from near the Van Duzen River, Humboldt County, California. This elegant and beautiful species at first glance might be confused with Pterostichus amethystinus (Mann.), for it is of about the size of the normal individuals of the latter, is of somewhat similar color, and is to be found in the same terri- tory. Structurally, it is widely separated, much more brilliant, with the head larger, the prothorax much broader, with the basal impressions single, long and deep, and the posterior angles much more prominent ; the elytra elliptical, not parallel sided, the humeri well rounded and without having the humeral angles at all dentiform ; the intervals distinctly convex throughout, and the apex of the prosternum not margined behind. Though a member of the subgenus Hypherpes, to which belong all those American species without discal elytral foveae, it stands by itself. In habits, it is only approached by one other member of the subgenus, crenicollis, for it lives along the gravelly mar- gins of the small densely shaded streams which come down from the hills. Pterostichus amethystinus (Mann.) and its close relative, Pterostichus scutellaris Lee., are to be found only in the damp woods in or under old logs. Pterostichus beyeri Van Dyke, new species Elongate, subparallel, slightly convex, rufopiceous. Head large, but .5 mm. narrower than prothorax and about as long, frontal 72 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 grooves distinct though not prominent; eyes small and flattened; gense bulbous, invading much of the ocular area; mandibles long and but slightly curved, prognathous; antennas moderately stout, slightly enlarged apically, about reaching to hind angles of pro- thorax. Prothorax slightly longer than broad, narrowed posteriorly, apex feebly emarginate; base transverse, slightly more than one- third of the greatest width of prothorax; sides feebly arcuate and convergent backwards almost to hind angles where they become sinuate; hind angles small, bluntly right-angled, lateral margins fine; disc feebly convex, the median longitudinal groove vague, the pos- terior lacking; basal impressions single, broadly though shallowly impressed, the basal margin only evident close to angles. Elytra slightly longer than head and prothorax combined, barely 5 mm. broader than prothorax, elongate elliptical; humeri distinct, humeral angles not dentiform; disc slightly convex, the striae well impressed, simple and complete, the intervals slightly convex, a bit flattened apically and without dorsal foveae; scutellar stria distinct, short and within base of first interval. Legs rather slender, anterior femora robust; posterior trochanters almost one-half length of femora and blunt at apex; first segment of hind tarsi vaguely grooved on outer side. Apex of prosternum not margined. Beneath moderately smooth and shining. Length, 12.5 mm.; breadth, 3.75 mm. Holotype, male (No. 1823, Mus. Calif. Acad. Sci.), in my collection, captured in the Bitter Root Mountains, Montana, by Mr. Gustav Beyer and by him very kindly presented to me. One other specimen, in the Beyer collection, has been seen. This species is somewhat related to Pterostichus caligans Horn. It is of the same length, but broader, with the prothorax and elytra proportionally shorter, as compared with the length, the eyes slightly larger, the humeral angles not dentiform, the hind femora not so clavate nor the posterior trochanters so long and apically narrowed, and the posterior tarsi not so definitely grooved externally. To Pterostichus ro stratus Newm. it is even closer structurally, differing mainly by being smaller and less robust, with single basal prothoracic impression instead of double, and by having the elytral striae simple. This places it as an intermediate species between the group to which caligans belongs and rostratus, and shows that the two genera, Cylindro- charis ^ and LeptoferoniaJ established by Colonel Casey upon insufficient characters, should be suppressed. In this connec- tion, I will also state that Hyperphes Chaud. is a well-defined subgenus of Pterostichus and should include, not only those 7 “Memoirs on the Coleoptera,” VIII (1918), by Thomas L. Casey, Lan- caster, Penn., pp. 326 and 336.

The char- acters which are used to separate these are divergent ones of minor degree, whereas those which all of the species possess in common are fundamental. Pterostichus falli Van Dyke, new species Elongate, subparallel, slightly convex, rufous. Head large, .75 mm. narrower than prothorax and almost as long; frontal grooves dis- tinct; eyes rather small; gen^ bulbous and about as prominent as eyes; mandibles long and but slightly curved, prognathous; antennae moderately stout, distinctly enlarged apically, reaching a little be- yond basal angles of prothorax. Prothorax as long as broad, nar- rowed posteriorly, apex feebly emarginate, anterior angles evident but not prominent; base feebly emarginate, one-third the greatest breadth of prothorax; sides feebl}^ arcuate and convergent pos- teriorly, sinuate in front of hind angles, which are sharply right- angled; lateral margin fine; disc somewhat flattened, the median longitudinal groove clearly defined and almost reaching anterior and posterior margins; anterior transverse impression evident, the pos- terior a broad, shallow depression; basal impressions double, the inner distinct and of moderate length, the outer vague, small and close to hind angles; basal margin vague. Elytra equal in length to head and prothorax combined, slightly broader than prothorax; humeri distinct, the humeral angles vague; sides subparallel, but feebly arcuate; disc slightly convex, flattened at middle, striae dis- tinct and complete though finer apically, the intervals quite flat- tened and without dorsal foveae; scutellar stria fine, over .5 mm. in length and at base of first stria. Legs rather slender, femora not greatly developed, posterior trochanters not one-half length of femora and blunt at apex; first segment of hind tarsi distinctly grooved on outer side. Apex of prosternum distinctly margined. Beneath moderately smooth and shining. Length, 11 mm.; breadth, 3.25 mm. Holotype, male (No. 1824), and allotype, female (No. 1825, Mus. Calif. Acad. Sci.), in my collection, captured by myself in the canons on the east side of the hills east of Hollywood, Los Angeles County, California, January 9 and 4, 1912. Be- sides these there are seven other specimens in my collection which I have designated as paratypes and which were collected at various times in the type locality. It is named in honor of my good friend, Mr. Henry C. Fall, who has contributed so much to the advancement of our knowledge of the Coleoptera of western North America. 74 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 This species belongs with caligans and beyeri. It is, however, smaller than either, more distinctly flattened, with the prothorax more narrowed posteriorly, with two evident basal thoracic im- pressions, and the apex of the prosternum distinctly margined. Pterostichus termitiformis Van Dyke, new species Elongate, flattened, rufous, antennae, legs and under surface lighter. Head very large, as broad as prothorax and distinctly longer; front flattened: frontal grooves distinct, broadly though shallowly im- pressed; eyes small, flattened; genae not bulbous; sides of head pos- terior to eyes slightly arcuate and convergent posteriorly; mandibles long and but slightly curved, prognathous; antennae long, extending several segments beyond hind angles of prothorax and but slightly dilated apically. Prothorax as long as broad, cuneiform; apex evenly though shallowly arcuate; base moderately arcuate, its width almost one-half the greatest width of prothorax; sides feebly arcuate and convergent backwards, becoming slightly sinuate as they approach the hind angles, the latter right-angled; lateral margin fine; disc flattened, the median longitudinal groove distinctly defined at center, anterior transverse impression vague, the posterior shallowly im- pressed, basal impressions single, rather long and lunate, basal margin lacking. Elytra slightly longer than head and prothorax combined, almost 1 mm. broader than prothorax, elongate elliptical; humeri broadly rounded, without humeral angles; disc feebly convex, flattened at middle; striae simple and deeply impressed basally, finer apically, the intervals flattened though approaching convexity near base, without dorsal foveae; scutellar stria minute, punctiform, at base of second stria. Legs rather long and slender, femora not greatly developed, posterior trochanters not one-half length of femora and blunt at apex, the first and second segments of hind tarsi distinctly grooved on outer side. Apex of prosternum not margined. Beneath moderately smooth and shining. Length, 9.5 mm.; breadth, 3 mm. Holotype, male (No. 1826), allotype, female (No. 1827, Mus. Calif. Acad. Sci.), and paratype male in my collection, captured by myself at Marshfield, Oregon, the first on June 11, 1914, the others on June 10, 1914. They were found beneath deeply imbedded logs in the woods. This species is definitely allied to caligans, beyeri, and falli. It differs materially, though, in general appearance, propor- tionately larger head, and more delicate form generally. The non-bulbous genae will also serve to distinguish this species from its associates. The large head and mandibles and small prothorax give it an appearance not unlike that of a soldier termite, a resemblance which has suggested the specific name. OCTOBER, 1925] VAN DYKE HARPALIN^ 75 The last three species described belong to a peculiar group or assemblage within the subgenus Hyperphes of Pterostichus, the members of which are characterized in the main by being somewhat elongate and cylindrical, with small eyes, long for- ward projecting mandibles, often large femora, especially well- developed posterior trochanters, and, in the more divergent forms, with the antennae enlarged apically. These are all char- acters which are to be found among those Carabidae which live a burrowing life, and such is the case with those under dis- cussion, they being the most subterranean in their habits of the American species of this large genus. The California species are rarely found except during the winter or early spring months, being deep down in the ground during the dry sum- mers, as is the case with many of our earth-dwelling insects. The greater portion of this group is at present restricted to the Pacific Coast, but it is, no doubt, a very ancient one which was at one time widely distributed over the more northern parts of North America during later Pliocene times. Because of their specialized habits they could not readily migrate, and hence were in great part exterminated during the Great Ice Age, the species which remain to us today being but the relicts and those which dwelt in territory that suffered but little from the effects of that age. To this group belong the following spe- cies : grandiceps Chaud. and rostratus Newm. from the Appa- lachian region in general ; beyeri n. sp. and elongatus Schffr., from the northern Rocky Mountain region; arisonicus Schffr. from Arizona; and inanis Horn, angustus Dej., longicollis Lee., fuchsi Schffr., caligans Horn, falli n. sp., and termitiformis n. sp., from the Pacific Coast. Cylindrocharis sulcatula Casey and piceata Casey are absolute synonyms of Pterostichus ros- tratus Newm., the characters given for their separation being insufficient. Of the forms described by Colonel Casey under Leptoferonia, crucialis is but a weak phase of angustus, pumilis a slight variant of longicollis, fugax a synonym of fuchsi, lar- valis and humilis practically the same and at most but a sub- species of fuchsi, the posterior prothoracic angles being slightly more evident, and inopina a weak variant of ovicollis. The species of this group, like all species which are to any degree subterranean, are unstable and plastic and thus inclined to vary 76 THE PAN-PACIFIC ENTOMOLOGIST [VOL. II, NO. 2 greatly, especially if they range over a great extent of terri- tory, as do many of those mentioned above. Pterostichus lanei Van Dyke, new species Of moderate length and breadth, gracefully proportioned, black and shining, antennas, mouthparts and legs rufopiceous. Head of normal proportions, two-thirds breadth of prothorax and one-third longer than broad, convex; frontal grooves distinct but not promi- nent; mandibles normal; eyes prominent; antennas slender, extend- ing several segments beyond apex of posterior prothoracic angles. Prothorax over one-sixth broader than long, distinctly narrowed pos- teriorly; apex distinctly emarginate, anterior angles moderately prominent; base but slightly emarginate at middle; sides broadly arcuate for anterior three-fourths, straight and convergent to pos- terior angles; hind angles obtuse, rather sharply defined; lateral margin fine and well reflexed; disc convex, median longitudinal groove clearly and rather deeply impressed, almost complete; an- terior and posterior transverse impressions faintly defined; basal impressions single, deep and linear; a faint indication of a secondary impression at the sides of the broadened base of the preceding; the area close to the posterior angles somewhat flattened, thus making the angles more evident; base not margined. Elytra about one-sixth longer than head and prothorax combined, a third longer than broad, elliptical; humeri well rounded; disc convex; striae complete, deeply and uniformly impressed, the faintest indication only of punctures; scutellar stria distinct and of moderate length, the intervals convex, the third with a distinct fovea just anterior to the middle, and a second midway between that and the apex. Legs slender, femora moderately developed, posterior trochanters rather large; first three hind tarsal segments distinctly grooved on outer side. Beneath rather smooth and shining. Length, 11 mm.; breadth, 4 mm. Holotype, male (No. 1828, Mus. Calif. Acad. Sci.), in my collection, captured by Mr. Merton C. Lane at V/awawai, Washington, and kindly presented to me. Several paratypes are in Mr. Lane’s collection. This graceful black species is of about the size of some of the smaller specimens of Pterostichus vicinus Mann., and it somewhat suggests that, but is far less robust, with prothorax more narrowed posteriorly and humeri well rounded. Its struc- ture would place it near lachrymosus , particularly the posses- sion of two dorsal punctures and deep linear basal impressions to the prothorax, but it is not closely related to that nor to any of the species associated with that.

BLAISDELL, SR. San Francisco, California The following revised list of the species of Eleodes inhabit- ing America north of Mexico also includes those from the islands in the Pacific, adjacent to the mainland and from the islands in the Gulf of California. This list is intended to replace the one given by Leng in the Catalogue of the Coleoptera of America, north of Mexico. References are given for the spe- cies and phases not given in the Leng Catalogue. This list includes 106 species, 67 subspecies, and 12 varieties. In my Monograph of the Eleodiini (Bulletin 63, United States National Museum) no attempt was made to designate subspecies. In the present list this has been done, based on more recent observations. My conception of subspecies and varieties or races has very recently been stated in the Proc. Calif. Acad. Sci., Ser. 4, Vol. XIV, No. 16, September, 1925. For information regarding forms and for synonyms, see my Monograph and Leng’s Catalogue. Eleodes coloradensis Blais, was first recorded as humeralis Lee. forma tuhcrculo-muricata. Eleodes concinna Blais, was first considered as humeralis Lee. forma gramdato-muricata. Eleodes apprima Blais, was first given as laticollis forma insularis. Eleodes immunda Blais, was first given as hispilabris forma elongata. In all other cases where a form name has been raised to the rank of a variety or subspecies the name hereby validated has been marked as “new name” (n. n.). The diagnoses of two new subspecies are here included so the names can be used in this list : Eleodes liorni fenyesi Blaisdell, new subspecies Form quite similar to horni, but smaller, more slender, with the integuments more opaque ; pronotal punctuation denser and more distinct; clypeal surface scarcely at all rugose, smooth and flat between the punctures. 78 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

The type is a $ ; not a male, as stated in the original description (1893) and by Ottolengui (1895). Dyar (1896 and 1903) sinks the name to confusus; McDun- nough (1911) thought it $ mathewi; and Barnes & Mc- Dunnough (1917) sink it to mathewi; but apparently lack of sufficient material in the past was prohibitive to properly sort the various forms allied to hyperboreus. This lack of material, coupled with misdeterminations on the part of all authors, has led to a very general confusion of the names in the group. Some authors appear to desire to call all American species synonyms of the European H. ganna. Judging from several figures, this species is nearest to mcglashani, but we think entirely distinct. Both authors have independently examined all types involved except hyperboreus, which is unknown to us except from the literature and Moeschler’s figure of type (1862, Wien. Ent. Monat., VI, pi. I, f. 1), and pulcher, of which we possess specimens agreeing well with Grote’s figure of type (1864, Prbc. Ent. Soc. Phila., HI, 522, pi. V, f. 3).^ A resume of the species in key form may assist to sort them. We are inclined to think that each name so far proposed rep- resents a distinct species. H. roseicaput is the Mt.

Blaisdell, Sr., had presented to the Academy his entire collection of Coleoptera on the same terms under which the Van Dyke collection of Coleoptera was accepted by the Academy. Under these terms Dr. Blaisdell retains control of the collection during his lifetime, with the privilege of retaining any portions for study at home as he may require. When the Van Dyke and Blaisdell collections, which are comparable in size, are finally incorporated into the Academy collection, it will constitute a remarkably complete representation of the coleopterous fauna of the western United States, as well as an excellent general collection of beetles. These two collections supplement one another, so there is less duplication than one might expect. The Blaisdell collection is very complete in the Tenebrionidse, Melyridse and some other families, while the Van Dyke collection excels in the Carabidae, Elateridse, and certain groups of forests insects, such as the Buprestidae and Cerambycidse. — E.

OCTOBER, 1925] CHAMBERLIN LEPIDOSAPHES 85 A NEW SPECIES OF LEPIDOSAPHES FROM CHINA (HEMIPTERA, COCCID^^) BY JOSEPH CONRAD CHAMBERLIN Citrus Experiment Station, Riverside, California The species of Lepidosaphes, described below, is very similar in general appearance to L. heckii, the purple scale, with which it was originally confused. Morphologically, it is clearly dis- tinct therefrom, as shown below. I am indebted to Mr. E. E. Green and Professor G. F. Ferris for confirming my opinion relative to its status as a new species. Mr. Green suggests that it is possibly the same as L. euryce Kuwana, as described in the Proceedings California Academy of Sciences, Vol. HI, p. 80. That description is inadequate, however, to permit an exact determination, and consequently this form is best regarded, for the present at least, as distinct.

THE HATCHING OF THE EGGS OF PERIPSOCUS CALIFORNICUS BANKS BY SIBYL WACHTER Peripsociis calif ornicus Banks is a species of the family Pso- cidas (Corrodentia) . It is commonly found on the leaves and bark of several species of garden shrubs and trees. The eggs of this species are laid in masses of nine or ten on the underside of the leaves, beneath a silken web which is, as a rule, covered with a loosely woven canopy. Occasionally, the canopy is absent. Observed individuals have been seen to oviposit six masses of eggs within ten days’ time, the laying of each mass covering a period of from twenty-four to forty- eight hours. The eggs hatch in from eight to ten days from the time of laying. The first external indication of life in the eggs, as viewed under the binocular microscope, is the appearance of a black structure extending from the apex of the narrower anterior end of the transparent shell backward about a fifth of the length of the egg. It becomes very distinct the day before hatching. The immediate sign of hatching is the movement of this mech- anism or egg-burster, followed practically simultaneously by the appearance of a bubble of air at its basal extremity. Under the microscope the egg-burster appears as an elon- gated crescent-shaped saw, semi-circular at its basal extremity, 88 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 with the serrate edge extending from this point to its sharply pointed anterior end. The serrate edge indents one-third of its width. This mechanism is a part of the amnion, to which it is attached basally by strands of membrane slightly heavier than the rest of the amnion. In this latter structural detail of the egg-burster we are able to verify a previous statement of Peyerinoff, who described a frontal chitinous organ consisting of a dentate ridge upon the amnion of a young psocid. We came to this conclusion from observing the amnion slip from the embryo as the body worked itself free, for as it contracted into a wrinkled mass at the opening of the chorion, the amnion carried with it the tiny saw, with the aid of which the embryo had attained its freedom. Furthermore, after dissecting the embryo from the chorion when it was about to hatch, we were able to slip the embryo out of the amnion, the egg-burster remaining as a part of the amnion. In hatching, consecutive movements of the egg-burster in- crease gradually the extent of the area through which it works until it finally cuts through the chorion. Two or three move- ments are followed by a period of inactivity. In some instances these periods last five to ten minutes. At corresponding inter- vals bubbles of air may be seen passing into the oesophagus, where they increase in size and number as the process advances, and, passing down through the entire digestive tract, inflate the body. After a few movements of the egg-burster the basal end protrudes through the chorion, and at the break the edges wrinkle back as the opening increases. In the posterior region of the chorion deflation occurs, as though by the creation of a vacuum at that point, as the frontal area of the embryo breaks through and begins to push upward. At this time, which aver- ages five minutes from the first signs of activity, bubbles of air enter the alimentary canal in rapid succession, some six or eight following each swing of the egg-burster. This now moves through a considerable area. The direction of movement is back and forth in the direction of the longitudinal axis of the egg. Each proximal movement of the anterior extremity of the burster against the anterior extremity of the head of the em- bryo causes a very decided indentation at that point. This is followed by a distal movement of the burster upon which the OCTOBER, 1925] WACHTER PERIPSOCUS EGGS 89 membrane resumes its previous turgid condition. There is apparently a direct relation between the movements of the burster and the accumulation of air in the digestive tract by means of which the embryo issues from its membranal envelope. This, then, would indicate an additional use of the burster. The amnion tears triangularly from the basal extremity of the burster toward its anterior extremity. The pressure exerted upon the inflated body by the proximal movement of the burster would thus seem to play some part in freeing the embryo. Pre- vious references to the function or air and the use of the burster in the hatching of the Psocidae have been reviewed by Knab.^ In emerging from the chorion the embryo takes barely a minute to attain an upright position. The body rotates continu- ally in line with the position of the egg and soon bends for- ward, so that the burster is hidden from view. It is covered with the amnion and presents a smooth transparent appearance with distinct black eye-spots, which appear soon after emer- gence. The interior is still filled with air bubbles. As the anterior end bends forward and down, almost touching the chorion, the amnion snaps off, splitting just below the eyes, and is thrown off by pressure from within, a part of it remain- ing as a wrinkled mass at the split in the chorion and a part extending backward from the burster in the form of a minute triangle. The body of the insect now straightens out, the con- striction between the head and thorax becomes evident, the legs are raised and begin to move with considerable rapidity toward and away from the body, and the palps and antennae are gently waved. The slipping off of the amnion from the time the body bends over to the time of the freedom of the appendages, and backward movement of the body into an upright position aver- ages three minutes. The entire hatching period of the egg varies from twenty to forty minutes. Its length seems to be deter- mined largely by the duration of the intervals of inactivity of the burster and the time needed to accumulate air bubbles in the first stages of hatching. After moving the appendages up and down for a few mo- ments, the insect moves forward to rest lightly on its delicate legs, and finally walks away from the egg mass. It remains quite inaxtive for a time except for slight movements of the abdomen, in which the air bubbles are still visible. These grad- ually disappear. Five minutes later the psocid walks away and for several hours remains relatively inactive. 1 Knab, Frederick, The Role of Air in the Ecdysis of Insects. Proc. Ent.

BLAISDELL Colonel Thomas Lincoln Casey, the well-known coleopterist, retired engineer of the United States Army, died at his resi- dence in the Stoneleigh Apartments, Connecticut Avenue and L Streets, Washington, D. C., in the early morning of Feb- ruary 3, 1925, at the age of 67 years. He had been ailing and unable to attend to his entomological work for considerable time. The funeral services were conducted at his residence, and he was buried on February 6, in the Arlington Cemetery with full military honors. Born at West Point, New York, Colonel Casey was the son of the late General Thomas Lincoln Casey and Mrs. Emma Weir Casey, and was the brother of Edward Pearce Casey, a noted architect. Colonel Casey was a member of the Class of 1877 at Yale and was graduated from the United States Military Academy in 1879, and entered the Engineer Corps of the Army. He was promoted to the grade of first lieutenant in 1881 and of captain in July, 1888. He was made a major in 1898 and a lieutenant- colonel in 1906. He became a colonel in September, 1909. He married Miss Laura Welsh of Philadelphia in 1898. During the Spanish-American War Colonel Casey was in charge of the defense of Hampton Roads, Virginia. He had also been at many stations, in charge of river and harbor improvements. He had the distinction of having been an assistant astronomer under Professor Simon Newcomb on an expedition to Cape of Good Hope in 1882 to make a study of the planet Venus, He was a member of the Gree Company Commission to Texas in 1886 and of the Mississippi River Commission in 1902-1906. He also served on numerous other special boards, doing vari- ous kinds of engineering and scientific research. In 1904 he was in charge of the United States Engineering Exhibit at the St. Louis Exposition, and between the years 1906 and 1910 he was also an engineer and secretary of the lighthouse board. He was retired from active service in the Army in 1912. Colonel Casey was a member of the New York Academy of Sciences, the Philadelphia Academy of Natural Sciences, American Society of Naturalists, the Washington Academy of OCTOBER, 1925] BLAISDELL T. L. CASEY 91 Sciences, Astronomical Society of the Pacific, the University and Century Clubs of New York and the Metropolitan, Army, Navy, and Chevy Chase Clubs of Washington, D. C. Personally, I first began to correspond with Colonel Casey about 1890. My letter file yields a letter dated June 30, 1891. For several years I submitted material to him for identifica- tion, both while I was resident at San Diego and for the eight and a half years that I lived at Mokelumne Hill, Calaveras County. The results of my collecting can be traced through his writings. I had the pleasure of visiting him in Washing- ton in 1909, v\^hile I was in that city indexing my Monograph on the Eleodiini. I called at his apartment in Stoneleigh Court and from there we went to his mother’s residence at 1419 K Street, N. W. Washington. It was there that I examined a number of his types. Colonel Casey was a most hospitable host. In conversation he told me that he worked but three hours a day. He explained how he arranged and studied the specimens and species before he began to write. He endeavored to be very careful in draw- ing up his descriptions, and he recorded the cha.racters of the beetles as he saw and interpreted them, not always as we would have analyzed them — but, then, how many of us see things as others see them? Colonel Casey has opened up many lines of discussion regarding the question of species, subspecies, and forms. Time will prove whether or not his views are correct. At present it appears that time will work in his favor, if the recent studies in S erica and Donacia are any criteria. Critics had better remain conservative until more work has been done on the genital characters. Colonel Casey’s decisions have been freely criticized. He has made many more mistakes than some other writers because he has done many times more work than they have. The works of Dr. George Horn yield as many errors, if his writings on the Tenebrionidse can be taken as a criterion. Dr. Horn was too conservative and thereby retarded the science of taxonomy. Colonel Casey advanced taxonomy too rapidly. In spite of all this we are advancing sanely, and the best of us can only hope to add our mite to the grand total of the world’s knowledge. 92 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

Great Abundance of Crickets in the San Francisco Bay Region On several nights this last August, during a period of unusual humidity just preceding a storm, great numbers of the common field cricket were attracted to the lights in the various cities about San Francisco Bay. During the day the horde sought shelter wherever they could find it, and as a result congregated in the stores in such numbers that many of the merchants became much worried lest their goods be injured. This is the most numerous appearance of these insects in this territory of which I know. — Edwin C. Van Dyke. OCTOBER, 1925] LARSON BEAN MITES 93 FURTHER NOTES ON HUMAN SUFFERING CAUSED BY MITES, PEDICULOIDES VENTRICOSUS NEWP. BY A. 0. LARSON Bureau of Entomology, United States Department of Agriculture In an earlier article (Jour. Econ. Ent., Vol. 13, No. 3, p. 322) the writer described the effects of injuries which he received from the bites of the mites Pediculoides ventricosus Newp. while handling weevily beans and cowpeas. As he was hand- ling these mite-infested seeds daily, it was impossible to deter- mine how soon the characteristic dermatitis appeared after the bite had occurred, but he was of the opinion that the burning sensation began within a very short time. On a number of occa- sions the writer and co-workers have had minor attacks from these mites, but, owing to the nature of the work, they have usually been uncertain as to the time elapsing before discom- fort became noticeable or before the appearance of reddened spots. They thought that discomfort came within a few min- utes, and that the spots always appeared in less than twenty- four hours. They noticed a difference in susceptibility to the injury. On one occasion, when three persons were similarly exposed to the attack of mites, one who had red hair and a ruddy complexion was injured much worse than either of the others, while the writer showed very much less injury than the others. In describing the effects of applications of these mites to various parts of the body, Dr. H. E. Ewing' (Can. Ent., Vol. 54, No. 5, p. 108) says: ^‘The appearance of reddened spots, each with a small papule in the center, was noted the day fol- lowing application. These spots usually did not develop into wheals, but did itch considerably.” Since reading the above statements, the writer and co- workers, to their sorrow, have had another opportunity to get first-hand information. On Monday, September 15, a laborer, James Petersen, began sorting beans in the laboratory on a specially prepared table. He used as a stopper at the lower end of the table a small sample bag containing about one and one-half pounds of beans, to prevent the beans on the table 94 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 2 from rolling off while they were being examined. Some time during the day he substituted a larger bag filled with weevily cowpeas. Tuesday morning he said he had an “awful dose of hives” all over his arms and body. The peculiar thing about these hives was that none were located on his legs. After an examination I told him that his hives looked like mite bites. There were no mites in the beans he was examining, and I knew of no mites in the laboratory, but if mites had been crawl- ing onto him from beans stored near by, they would have at- tacked his legs as well as his body. He was left alone on Tuesday, as he had been on Monday. Wednesday morning, when I received word that he was unable to return to work, I began the work where he had left off, but as soon as I picked up the bag he had been using at the lower end of the table, I knew why he was not at work. This bag was filled with weevily cowpeas, which were badly infested with mites. He had used the bag, not only to keep the beans from rolling off the lower end of the table, but he had used it to wipe the dust off the table after removing each small lot of beans. The mites from the bag had thus been spread all over the table and had crawled onto his arms and body. His legs were not in contact with the table, and were uninjured. After removing the bag of mite-infested cowpeas and mak- ing what I thought was a thorough cleaning of the table and surroundings, I went to see Mr. Petersen. His body and arms were a solid red blotch “burning like fire.” He had first noticed this burning on Monday afternoon. It caused much discom- fort during that night, but the addition of more mites on Tues- day made it almost unbearable. The external burning was sup- plemented by turns of fever followed by a cold sweat, making sleep impossible. As the writer, on previous occasions, had obtained relief by bathing in warm soapy water and then apply- ing talcum powder, this treatment was recommended and im- mediately gave temporary relief. During the night he obtained little sleep between the several necessary applications of talcum powder. He was back at work Thursday morning. On Wednesday morning I went over the table with a kero- sene-soaked cloth to remove all mites after I had burned the mite-infested bag of cowpeas. During the afternoon the writer OCTOBER, 1925] LARSON BEAN MITES 95 and a co-laborer, Mr. C. K. Fisher, sorted beans on the table. In a short time Mr. Fisher was scratching where mites had bitten his arms and body, and before evening wheals had ap- peared. The writer, having an equal opportunity during the afternoon to become infested with mites which had remained in the cracks of the table, and a better opportunity to become infested in the forenoon while removing the infested bag of cowpeas and cleaning the table, first became aware of their ill-effects when he awoke at 5 a. m. on Thursday morning, scratching a few burning wheals on his body and arms. Mr. Fisher had not been in the laboratory since 7 :30' a. m. the pre- vious Saturday, consequently the bites caused wheals to appear on his body in less than three hours. The table was again gone over with kerosene on Thursday morning and work was resumed, with no new attack of mites. At the end of a week the marks were plainly visible on the arms of Mr. Petersen and Mr. Fisher. In this instance, as in the one cited above, not only was the writer injured much less than the other men, but a longer time elapsed before the injuries became visible, and their disappear- ance was more rapid. This indicates that different individuals may not react similarly either in the severity of the injury or the length of time required for the wheals and pustules to appear. It may suggest a tendency toward an acquired immu- nity to the effects normally produced by the first attack of the mites. Where to Find Zacotus matthewsi Lee. This brilliant purplish copper-colored carabid ranges from British Columbia to northern California and in the north as far east as the Bitter Root Mountains of Montana. It prefers damp situations, and in the humid lowlands is to be found in the woods under cover not far from streams or springs. It is here of a very brilliant copper color and rather hard to find because of the immense amount of cover. On the high Cas- cades, however, and the mountains of Idaho as well, as I am told by Mr. Merton C. Lane, it is to be found far more fre- quently. Here, close to timber line, where there is but little litter and the old logs rest upon hard ground, they are readily observed once the logs are turned over. The more alpine forms are also less robust, narrower, and less brilliant. — Edwin C. Van Dyke. THE PAN-PACIFIC ENTOMOLOGIST Published quarterly by the Pacific Coast Entomological Society in co-operation with the California Academy of Sciences E. P. Van Duzee^ Editor F. E. Blaisdell, M.

C., and Dr. J. M. Swain, Dominion Forest Entomologist at Ottawa, were welcome visitors at the Academy of Sciences in October. On their return from the South a week later, they were guests of honor at a special meeting of the Society, at which they gave an interesting account of the work in forest entomology being done in the Dominion of Canada. Mr. Dudley Moulton, Horticultural Commissioner of the County of San Francisco, and well known as a careful student of the Thysanoptera, has prepared and is sending free to ento- mologists interested in collecting Thrips, a small “Thysanop- tera Collecting Kit,” containing vials, alcohol, a brush and memorandum sheets, and especially wishes to place them with entomologists in foreign countries. If you desire one of these collecting outfits, address Dudley Moulton, 244 California street, San Francisco, California. Mr. J. C. Hamlin writes us that an official notice, under date of September 28, has been received from Mexico City, telling of the death of Professor Jose Maria Gallegos, in the perform- ance of his duty in Payo Obispo, Q. R., on September 23, 1925. Professor Gallegos was a versatile student of nature, his col- lecting showing a broad range of interest. His chief activities were, perhaps, centered in the birds, in which field he exhib- ited skill as a preparator rarely excelled, combined with a tire- less energy. Much of his recent work had been directed toward a study of the fauna of the State of Fower California, and included work on the interesting insect fauna of that penin- sula. Friends of Professor Gallegos will always remember him as a gentleman endowed with a most pleasing personality. He was a distinguished member of the Administration and of the Society of Biological Sciences of Mexico. Both of these insti- tutions are most unfortunate in the loss of this worker in the prime of his life.

The Pan-Pacific Entomologist Vol. II, No. 3 January, 1926 BIOLOGICAL NOTES ON IMPORTANT OPUNTIA INSECTS OE THE UNITED STATES ^ BY JOHN C. HAMLIN Fresno, California INTRODUCTION The general data recorded in this paper were secured dur- ing the writer’s North American work in connection with the Australian Commonwealth Prickly-pear Board’s project for the biological control of the prickly-pear pests acclimated in Queens- land and New South Wales. An earlier paper on this subject was published in the July, 1925, number of this journal. A Species Attacking the New Growth Mimorista flavidissimalis Grote ^ DESCRIPTIVE Adult. The adult, expanding about one inch, is bright yellow with darker markings arranged in four irregular transverse bands on the wings. These markings vary from an incon- spicuous brown to a distinct blackish-brown color. Egg. To the unaided eye the egg appears as a tiny, sub- circular, irridescent disc attached to the flat surface of the joint. The finely roughened surface is very slightly but regularly convexed. The disc measures 0.75 mm. in diameter. Larva. Eull-grown larvae measure about one-half inch in length, and are of a yellowish-white color. Pupa. The pupa is about two-fifths of an inch long, of a polished light-brown color, with the head blackish. It rests against the cactus joint and is covered by a whitish, convexed cocoon of thin, tightly woven material. Pupation usually takes place in wrinkles of dried joints. LIFE HISTORY The eggs are deposited singly or in small groups on the newly formed joints, usually near the upper edges. Often two or 1 For determinations of species mentioned herein the author is in- debted to the appropriate specialists of the Taxonomic Division, United States Bureau of Entomology. 2 Order Lepidoptera, Family Pyralidae. 98 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 , more eggs overlap. The extremes of the incubation period were not determined, but in midsummer it is from three to five days. Soon after hatching the larvae spin a delicate web, beneath which they feed, either singly or several beneath one web. They are not entirely external feeders, for they are frequently found within the young joints or nopalitos.^ When fully developed, the larvae spin their characteristic cocoons on the joints which have succumbed to their attack, or occasionally on nearby living joints. Duration of the larval and the pupal stages were not independently determined. During midsummer a generation is produced in four weeks. The shortest life cycle was recorded at Uvalde, Texas, in June, 1921. Newly emerged adults were caged on June 1 with plants bearing nopalitos. The first moths of the succeeding generation appeared on June 26, while the peak of emergence was reached on June 29. From the four females originally placed in this cage were reared 221 adults of the next genera- tion. These figures indicate a minimum egg-deposition of fifty- five per female, but the actual number laid was probably in excess of the number of individuals successfully reaching the imaginal condition. In the lower Rio Grande Valley, where M. Uavidissimalis is most abundant, the species appears to have about eight genera- tions annually. The first generation is completed at Browns- ville, Texas, early in April. The last generation of autumn, all stages of which show a greatly retarded development, extends over the mild winter. The pupal condition is undoubtedly the stage in which the species passes the winter farther north. HABITS AND FOOD PLANTS During the day the adults rest on shaded parts of the plant. At dusk they may be seen flying about among the cactus clumps, usually alighting on the young joints. Mating and oviposition have not been observed, but these activities evidently transpire at night. This species has never been found attacking any cacti other than the platyopuntias.^ Moreover, in the field its attack was observed to be confined to the young, tender joints of these 3 Nopalito is a Spanish term which refers to a definite stage in the growth of the Opuntia joint, being applied to the tender, newly formed joint before it has thrown off the rudimentary true leaves. JANUARY, 1926 ] HAMLIN OPUNTIA INSECTS 99 cacti. Among the Opuntias, however, no restriction to species was noted. On one occasion a distinct variation in feeding habit was observed in a cage poorly supplied with nopalitos. The heavy, basal joints ceased putting forth new joints, leaving the large number of larvae with an inadequate supply of dying nopalitos. When the cage was dismantled all nopalitos were dead, being very dry and hard. By chance, it was found that considerable numbers of the larvae had successfully met this condition by boring into the mature joints at the points of attachment of the dried nopalitos. Some individuals had penetrated the tough fiber to a depth of two inches, acting much as other internal feeders. INJURY Owing to the small size and tenderness of the joints against which Mimorista Paijidissimalis larvae direct their attack, these parts are very quickly killed. Even when only a few larvae are present their work weakens the attachment of the nopalito to the plant and it falls to the ground where, if not completely killed by the insects, it has not the substance to establish itself. Occasionally, joints recover from the attacks of the larvae, but they remain deformed. Such recovery is believed to be due to the eggs having been laid on small young joints which had toughened considerably. The many generations during the growing season and its attack against the new growth render this species a formidable enemy of the prickly-pears in the region where it is abundant. Were its distribution more general, it would rank among the most important Opuntia insects of the United States. DISTRIBUTION Hunter et al.^ noted the species as having a restricted range, recording it in Texas from Hallettsville and San Antonio, southward, and in Arizona from Tucson. While the writer has taken specimens at Uvalde, San Antonio, Victoria, and Browns- ville, Texas, and at Piedras Negras, Mexico, the species has been observed to be of importance only in the lower Rio Grande Valley. This distribution seems certainly to be correlated with 4 The Principal Cactus Insects of the United States, by Hunter, W. D., Pratt, P. C., and Mitchell, J. D., U. S. D. A. Bur. Ent. Bull., 113, 1912. 100 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 moisture. Since young joints are required monthly through- out the summer for oviposition and larval development, those sections of the cactus country which are very dry during mid- summer are not suited to continuous propagation of large numbers of this species. In this connection it is of interest to note that the so-called prickly-pear rat {Neotoma micropus Baird), in pruning the Opuntia plants during feeding, stimulates the production of new joints which, occurring throughout the summer, constitute a considerable factor in the propagation of this insect. NATURAL ENEMIES The foremost parasite of Mimorista Havidissimalis is a spe- cies of Casinaria, probably infesta (Cresson). A collection of 100 Mimorista larvae from Brownsville, Texas, in June pro- duced 20 of these ichneunionid parasites. Another parasite, less abundant than the former, is Eiphosonia brucsi Cushman. Cottony Cochineal Insects : Dactylopius spp.^ Two species of wild or cottony cochineal insects are impor- tant enemies of Opuntia in the United States. These are Dacty- lopius tomentosus Lamarck and D. confusus Cockerell. As implied by the common names, these forms are distinguished from the dye-producing species by the profuse covering of pure white wax in contrast to the light, powdery covering of the latter. Dactylopius tomentosus (Lamarck) The adult female is hidden by the tomentose wax covering. These white clumps contain several female insects. The indi- vidual clumps are of somewhat greater extent and are hardly so symmetrical as are those of D. confusus Ckll, The insects themselves are soft-bodied, rounded, and of a dull-reddish color. The adult males are rarely seen in the field, although they are produced in abundance. The body of the male is 1 mm. long, while its length, inclusive of the wings, is nearly 2 mm. From the posterior end of the abdomen project two slender processes 4 Order Hemiptera, Family Coccidee. JANUARY, 1926] HAMLIN OPUNTIA INSECTS 101 slightly more than 2 mm, in length. The male is red, with the wings and abdominal processes pure white. SEASONAL HISTORY The mature females produce living young which crawl about over the plant until a suitable feeding place is found. Here they insert their probosces and suck the juices of the plant. After once becoming settled these “crawlers’’ are unable to move to another location. The males are produced in small white tubes which appear on end in the waxy covering of the female. Several generations are produced during the summer. It seems that a generation is produced in from five to seven weeks. The crawlers of the last generation in autumn seek shel- tered places to settle themselves for the winter. It has been observed that the overwintering brood lives upon the roots or stems beneath the surface of the ground or next to the ground on prostrate-growing or fallen joints. HABITS The summer broods of crawlers travel upward and cluster on the topmost spines of the plant upon which they were devel- oped. Undoubtedly, this habit greatly influences the dissemi- nation of the species, for such tiny creatures, with the few strands of the tomentum already formed, would be carried very considerable distances by the wind. FOOD PLANTS Dactylopius tomentosus Lamarck has been found only on Opuntia. In the field, however, the species occurs as distinct biological strains or races. Thus, cochineals have been found feeding upon certain prickly-pears which refused to feed upon certain other species. The Texas strain has been found to prefer Opuntia lindheimeri Engelm., while the strain from Tucson, Arizona, lives upon a white-spined Opuntia, and the Chico, California, strain prefers prickly-pear different from either of the former. After due time, and under the stress of starvation, a very small percentage of a new generation may be induced to settle upon a species of Opuntia which was pre- viously refused when its favorite type was also available. While it is known that these strains can adapt themselves to groups of Opuntias other than those preferred, the extent of such capa- bilities has not been determined. Structurally, these strains 102 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 were not distinguishable, and all were determined as belonging to this species. INJURY TO PLANT The etfect of the sucking of these insects is to devitalize the plant and finally to cause affected joints to dry out completely. The new growth is effectually checked when these insects are abundant, for the crawlers settle upon it in preference to the older joints and quickly cause it to drop from the plant. After its severance from the plant the insects, being unable to migrate, continue their sucking until it is completely killed. Thus, the injury of this cochineal is effected by preventing new growth and by a gradual killing of the older terminal joints. DISTRIBUTION Dactylopius tomentosus Lamarck has been secured by the writer from Chico, California; Tucson, Arizona; and Uvalde, Texas. Hunter el alP recorded the species from New Mexico, Arizona, and Mexico. Dactylopius confusus (Cockerell) This insect presents very much the same appearance as the foregoing species, but the white clumps are somewhat smoother and appear a little more rounded. Its seasonal history, habits, and character of injury are very similar to those of its con- genitor. This species seems to be even more closely restricted in feeding habits than the preceding species. The writer has collected it in Florida at Miami, Coconut Grove, Larkin, West Palm Beach, Palatka, and Gainesville, and at Brownsville, Texas. NATURAL ENEMIES OF THE COCHINEALS Aside from the eleven enemies recorded,® the writer has found Zophodia quadric olorella (Dyar) ® to be a most impor- tant predator in material from both Brownsville, Texas, and Miami, Florida. The larvae of this moth burrow beneath the waxy covering of the cochineal clumps and devour the soft- bodied coccids. When fully developed, the predaceous larvae spin cocoons beneath the cochineal wax, leaving no external evidence that the waxy material of the former inhabitant now 5 U. S. D. A. Bur. Ent. Bull., 113, 1912. 6 This species is assigned to the genus Poujadia in the Barnes and Mc- Dunnough catalogue, but Doctor Dyar tells me that it is a Phycetine and should go in Zophodia. JANUARY, 1926] HAMLIN OPUNTIA INSECTS 103 covers only the cocoons of a predator. As many as three cocoons of this moth have been found under a single cochineal clump, while, occasionally, four or five small larvse have been found beneath a waxy mass feeding on the cochineals. A Species Inhibiting the Development of Seeds Asphondylia OPUNTIA Felt The mosquito-like adult has never been seen in the field by the writer. During March the puparia may be seen protrud- ing from the previous season’s fruits, quite commonly upward of fifty projecting from one fruit. The midges issue in the canyon country north of Uvalde, Texas, during the latter half of March. At this time the flowers of Opuntia have not opened. In early May a slight yellowing of certain fruits indicates the presence of larvae, which may be found in the interstices formed by the rudimentary seeds. They are extremely small and are barely distinguishable to the naked eye as tiny dots of light yellow. There are no feeding marks to be seen on the seeds, and the fruits show a normal degree of turgidity. Later observations showed no change except a deepening of the yellow color of affected fruits, and perhaps the production of one or more small joints or fruits from the infested fruit. In August the larvae were of the same size and color as when first observed, and no damage to the seeds was apparent. The seeds showed just the same state of development observed in May. In October no changes in the larvae or seeds were apparent. Likewise, in December no changes could be noted. During midwinter the larvae evidently have a greatly acceler- ated development, since they attain a fair size and destroy the interior of the fruit just before the puparia protrude in March. There is, then, only one generation annually. From the above observations it seems that the larvae are greatly retarded in their development, so that for about nine months they undergo no perceptible changes. Moreover, it seems that their effect of transforming the fruit functionally from a reproductive to a vegetative part is accomplished without entering the seeds or fleshy interior of the fruit. This inhibitory effect upon the seeds may be caused by a secretion. This species is widely distributed. It is recorded ® from 7 Order Diptera, Family Cecidomyiidae. 8 U. S. D. A. Bur. Ent.

An Opuntia Longicorn Moneilema crassa Le Conte ® The large, robust, wingless adult is from three-fifths to four- fifths of an inch in length. The female is shining black through- out, while, anteriorly, the elytra of the male are sparsely mottled with whitish. The eggs are cylindrical with both ends abruptly and regu- larly convexed, measuring 3.00 to 3.25 mm. in length and 1.50 to 1.75 mm. in width. They are deposited either on cactus or soil where the plant and the earth make contact. The larvae enter the plant just below the surface of the soil, arranging their cells so that the excess moisture is absorbed by the ground immediately adjacent. In many instances this wet soil is shaped to form the lower part of the larval cell. Pupation takes place in the earth just below the scene of the larval activities. The spheroidal cocoon is slightly more than one inch in diameter and is composed largely of earth, but may contain a small amount of the fibers of the plant. This Opuntia longicorn has two generations annually in the Uvalde, Texas, region. The winter is passed in the larval stage and the spring adults appear in greatest abundance during late April and early May. Second generation adults appear in Sep- tember. The adults live from two to three months in summer. Various species of Opuntia and Echinocereus, called “pita- haya,” are the plants in which this species breeds in Southwest Texas. The adults feed preferably upon the young, tender joints or nopalitos, but also quite commonly on the fruits and older joints. During the day the adults secrete themselves about the base of the cactus clump or among the debris which constitutes the massive covering of the pear-rat’s^® abode. With the approach of dusk the first few beetles leave their shelter and crawl upon the plants, where they feed and mate during the night. In the morning, when the sun’s rays strike them, they descend to cover. It was, therefore, found that the most effective period of the day for collecting them is between dawn and about 8 a. m. 9 Order Coleoptera, Family Cerambycidse. 10 Neotoma micro-pus Baird. JANUARY, 1926] HAMLIN OPUNTIA INSECTS 105 Indeed, with little effort one may capture during this brief period more beetles than could be collected by several persons during the day by the laborious method of chopping and mov- ing the heavy Opuntia plants. On cloudy days the beetles remain on the upper portions of the plant until much later in the day. On account of the semi-subterranean life of the larvae and the nocturnal habits of the adults, these insects are always a rather obscure factor in the cactus-insect complex, despite the importance of their injury. Two reliable indications will serve to reveal the presence of the insect. First, infested plants are in a disheveled state, much fallen, and the basal portions are in a state of decomposition. This condition results from the larval attack and constitutes the principal injury accomplished by this species. Second, the feeding marks of the adults on the upper portions of the plant show the presence of the beetles in the immediate vicinity, for, being dependent upon crawling as a means of locomotion, they do not travel far. This gnaw- ing of the joints is insignificant in comparison to the larval damage. The species was collected at many points in the field in the Uvalde, Texas, region. Its habitat is the dry, rolling country of Southwest Texas. NATURAL ENEMIES Two parasites of M. crassum have come under observation. The first developed from larvae collected in the La Pryor, Texas, district during December, 1920. During the following spring three puparia of this dipterous parasite were found within one dead larva. This Moneilema larva was destroyed just prior to the pupation of the other individuals. Unfortu- nately, these parasites were lost during the interval between dismantling the Florida station and the belated establishment of Texas headquarters. During the autumn of 1922, Mr. E. Mortensen found at Uvalde, Texas, a minute egg-parasite destroying practically all of the eggs deposited by large stocks of caged beetles. This parasite has been described as a new species under the name of Oencyrtus moneilcmce Gahan. 11 Proc. Ent. Soc. Wash., Vol. 27, 1925. 106 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

Hind wing: Pale, whitish, the veins and outer margin suffused with fus- cous; fringes luteous at base, a fuscous interline, and white tips. Beneath: General coloration much as above, somewhat paler; with an obsolescent blackish common line, on the hind wing marked on the veins only; a diffuse discal blotch on fore wing, and an obsoles- cent discal dot on hind wing. Expanse, 41 mm. The roughened, although not tuberculate Irons, allies the in- sect to certain Rhizagrotis species, notably R. polingi B. and Benj., to which it seems allied by habitus. The rather rough thorax suggests Epipsilia, but the vestiture is composed of bi- and trifurcate narrow scales mixed with some hair. The present species, like polingi, is another connecting link between the genera of the “Euxoa^ and Lycophotia groups. European workers would probably place it in Lycophotia or '"Agrotis,” but because of the Irons we prefer to place it in Rhizagrotis . Superficially, the appearance is very similar to smooth-looking ‘‘Agr Otis’’ aurulenta Sm,, but it may be distinguished by its black-sided palpi, more roughened Irons, and broader-scaled thoracic vestiture.

In 1906 Hampson recognized a mixed type series of falsa Grt. and restricted the name to the 6 type, renaming the spe- cies represented by the 9 type Bryomima fallax. In Nov. ZooL, 1918, he attempted to change the name falsa back to Bryomima (type 2 ) and renamed the 6 type Miselia micta, on the grounds that the 6 type did not fit the original description in regard to its hairy eyes. We scarcely see how this enters the matter. When Hamp- son first selected one species to hold the nam^ falsa out of a mixed type series, he might well have selected the species best fitting the original description. However, he chose the hairy- eyed species to hold the name falsa, and we do not see how this fixation can be discarded even by himself. We might mention that we find nothing in the code which states that a description must be either adequate or accurate, and call attention to the fact that a number of authors have erroneously described hairy-eyed forms as possessing smooth eyes, and vice versa. In fact, the unique type of Grote’s ''Ma- mestra'' ferrealis is in Oligia.^ We are retaining falsa for the hairy-eyed species and fallax for the lashed-eyed species. Septis ona Sm. 1909, Smith, Jour.

Head and thorax luteous, strongly tinged with rufous-purple. Fore wing: Ground color luteous, tinged and irrorated with rufous-purple; ordinary lines except the s. t. of rufous-purple, single; basal line obsolescent; t. a. line in the form of three waves from costa to inner margin; median shade broad, outwardly oblique from costa through cell filling in space between the ill-defined, luteous, blotchy stigmata, angled at base of reniform, thence inwardly oblique; t. p. line outwardly oblique on costa, thence parallel to costa, thence out- wardly oblique to a sharp point on vein 6, thence inwardly oblique and produced to points on the veins, which are strongly marked by rufous-purple; s. t. line pale, rather as a waved transverse of ground color bordered by a slight powdering of rufous-purple scales than as a real line; terminal line thin, more or less interrupted by the veins; fringe rufous-purple, obscurely mottled and interlined, paler basally. Hind wing: Black, tinged with rufous-purple, only a slight trace of luteous on disc, fringe rufous-purple, paler basally. Beneath, ground color luteous, strongly suffused with rufous-purple, and powdered by black scales, a common black line across wings, discal black dot on hind wing only; veins, especially of hind wing, darkened. Expanse: 6, 37 mm.; 9, 34 mm. Similar to Luperina venosa Sm. ; somewhat smaller, smoother appearing ; the fore wing, with the fuscous scales and markings, replaced by rufous-purple; the hind wing much darker, black tinged with rufuus-purple, and nearly lacking yellowish on upper side.

We par- ticularly call attention to the dentate but evenly curved t. p. line and the short dash in the cell which takes the place of the orbicular. Besides a short series from several Colorado local!- 110 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

A race, or very likely only a maculation form, with mark- ings similar to those of typical camina, but with the black dash which takes the place of the orbicular greatly elongated, dis- tally nearly making contact with the reniform and continued mesad to the base of the wing. Type locality: Deer Creek, Provo Canon, Utah. Number and sexes of types: Holotype 6, lO-IX-18; one 6 paratype, id., 22-VIII-13. Notes : Barnes collection, from Tom Spalding. Platyperigea camina race beta Barnes and Benjamin, nov. In general similar to typical camina, but the t. p. line when visible is much more strongly dentate, its course less evenly curved, a tooth produced inwardly nearly to the reniform and another strong inward tooth in the submedian fold, nearly mak- ing contact with a strong outward tooth on the t. a. line. T. a, and t. p. lines distally marked with white. In many specimens it is difficult to see the exact course of the lines, but the present form is usually easily sorted on its decidedly strigate appear- ance. Such differences of appearance and markings have nearly universally been accepted as of specific value. Possibly beta is a valid species. However, we prefer to call it a subspecies (race) until there is further evidence of its relationship to other described forms. It is represented in the Barnes collection from Jemez Springs, New Mexico, and Clark County, Nevada, as well as from the type localities.

BENJAMIN Decatur, Illinois Polia wyatti Barnes and Benjamin, sp. nov. Head, thorax, and fore wing pale gray, with a few luteous and black scales; basal line faintly geminate, its mesial part deep black, erect on costa, produced along median vein, inwardly oblique to vein 1; a black dash from termination of basal line, in submedian fold, through about one-third of the t. a. space; t. a. line geminate, mesial part obsolescent, distal part black, outwardly oblique, waved from costa to below cell, excurved to base of claviform, strongly dentate inwardly on vein 1, thence strongly excurved to inner margin; orbicular large, rounded, white, filled with gray, and out- lined with black scales; two black spots on costa, one each side of the orbicular; claviform large, outlined by black, with pale gray fill- ing, extending to or nearly to the t. p. line; reniform large, irregular, pale, faintly outlined by black with central pale crescent outlined by gray, somewhat constricted in middle, distally making contact with the t. p. line, mesially produced as a point on median vein; t, p. geminate, its outer line obsolescent, inner line marked by black, pro- duced to long points on the veins, oblique on costa, excurved to veins 4 or 5, incurved to claviform, at the distal end of which it forms a small w-mark, outwardly oblique to vein 1, inwardly oblique to inner margin; s. t. line obsolescent, marked by some sagitate black dashes in a course nearly parallel to the outer margin; a ter- minal row of dots between the veins; fringe pale at base, interlined and checkered by blackish. Hind wing fuscous, with paler, broad, obsolescent median shade; with a thin dark terminal line; fringe luteous with a fuscous interline. Beneath: Fore wing dull gray; hind wing white, with a few scattered fuscous scales. Expanse, 40-44 mm. A peculiar species, with a rather rough front, but obviously not a Scotogramma. The habitus is that of a well-marked, narrow-winged lustralis, but structurally nearer to insolens. The eyes are strongly lashed from behind, and possibly a few lashes from near the base of the antennae, suggestive of Lasi- onycta. The fore tibiae are unarmed, and the tarsi are rather heavily spined, but not heavily enough to prohibit placement in Polia, which term we use in the sense of Hampson, knowing that the correct name is probably Hadena.

Papaipema dribi Barnes and Benjamin, sp. nov. Head and thorax purple-rufous; basal antennal segments white; tegulce white-tipped. Fore wing: Ground color yellow, strongly tinged with rufous and powdered with dull purplish scales; basal spot white or purple-gray; subbasal area concolorous with median area; subbasal line strongly excurved from costa to submedian fold, bent inwardly at base of cell; t. a. area purple-gray above vein 1; t. a. line double, angled inward on subcosta, thence outwardly ob- lique to median vein, incurved in submedian space, strongly excurved above inner margin; claviform indicated by a minute luteous-white spot defined by purple-gray, below which is another minute spot containing two white scales surrounded by purple-gray; orbicular rounded, white, defined by purple-gray with a rufous distal point; reniform large, oblique, constricted on inner side at middle, with a luteous center defined by rufous and surrounded by white spots defined by purple-gray; medial shade purple-gray, outwardly oblique from costa, inwardly oblique from cell; t. p. line double, excurved to about vein 4, incurved in submedian area; s. t. line irregular, its course not well defined; an apical yellowish patch; terminal line thin, purple-gray; fringe luteous at base, distally purple-gray, interlined with luteous and purple-gray. Hind wing luteous-white, suffused with rufous and purple-gray. Beneath: Luteous-white, tinged with rufous and purple-gray. Expanse, 38 mm. Allied to marginidens ; but with somewhat the habitus of merriccata. The genitalia, examined superficially, are much like those of marginidens , the clasper and ventral arm of the valve appearing shorter and heavier. Mr. Henry Bird has seen the specimen, which we had already compared with the various Western types in the United States National Museum, and agreed with us that a new species was involved. When asked to describe it he declined, but very kindly advised us to do so. Type locality : High Rolls, New Mexico. Number and sexes of types: Holotype 6, August, J. G. Bonniwell collector.

Prothorax robust, as broad as long, slightly narrowed posteriorly, apex shallowly but evenly emarginate, base almost trans- verse, sides distinctly arcuate throughout, hind angles rounded; lateral margins moderate, reflexed and with well-marked flattened fossae within, which broaden basally; disc convex, median longitu- dinal groove deeply impressed and almost complete, anterior trans- verse impression well defined, the posterior vague, basal impressions single, broad and deep posteriorly and coarsely irregularly punctured, a rounded tubercle to the outer side (in the paratype or second specimen this is less evident), the base not margined. Elytra three- fifths longer than head and prothorax combined, five-eighths as broad as long, elliptical; humeri well rounded, humeral angles absent; disc convex, striae deeply impressed, complete, uniform throughout, finely rather closely punctured, intervals convex, slightly crenulate and vaguely rugose near middle; third with four shallow foveae, the first about one-fourth distant from base, the second near the middle and the others closer together and not far from the apex; scutellar striae rather long and on either side of the suture at base. Legs fairly robust; first segment of posterior tarsi obscurely grooved at base on either side; posterior trochanters of moderate size. Apex of prosternum not margined. Beneath, with the sides of head finely rugose, the lateral thoracic sclerites and sides of first two abdominal segments rather coarsely punctured, the median portion of body with the abdomen posteriorly smooth and shining. Length, 13 mm.; breadth, 5 mm. Holotype, female (No. 1853, Mus. Calif. Acad. Sci.), and paratype female in my collection, captured on Iron Creek, sixty miles north of Nome, Alaska, August 23, 1913, by J. Aug. Kusche and by him kindly presented to me. This interesting and most distinct species should be associated 114 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 with Pterostichus punctatissimus Rand. It has the same general facies, and is about the size of a small specimen of the latter. It is in general less robust, its head and prothorax smaller, the elytra more elliptical, the intervals regular, and the thighs a clear orange-red instead of black. The males will, no doubt, be found to have the elytra more shining. Pterostichus pacificus Van Dyke, new species Small, robust yet graceful, shining, head and prothorax black, elytra piceous brown, mouthparts, antennae, legs, prothoracic epi- pleurae and epipleurae rufopiceous. Head rather large, slightly more than three-fifths as broad as prothorax; frontal grooves well im- pressed, non-punctate; mandibles of type usual in subgenus Cryobius; eyes moderately prominent (less convex than in riparius) ; antennae rather slender, extending beyond hind angles of prothorax. Pro- thorax slightly broader than long; apex emarginate; anterior angles prominent, base slightly emarginate at middle; sides narrowly arcu- ate from apex to one-fourth distance from base, there sinuate and straight to hind angles which are right-angled; lateral margin well defined and markedly reflexed; disc convex, median longitudinal groove sharply defined and almost complete, anterior transverse im- pression vague, the posterior distinctly defined; basal impressions each a single flat-bottomed pit projecting forward along the inner margin, rugosely punctured at bottom, without distinct carina near hind angles, base with indistinct margin near angles. Elytra one- fifth longer than head and prothorax combined, three-fifths as broad as long; humeri distinct though rounded, the sides moderately arcu- ate and rounded to sutural angles as usual, the margin fine; disc con- vex, slightly flattened at middle; striae clearly defined and complete, more deeply impressed basally and apically, punctuation obscure, intervals flattened at middle, somewhat convex near base and apex; third stria with a well-defined fovea one-third distance from base and another one-fourth distance from apex, scutellar stria rather long and well impressed. Legs slender, first three segments of hind tarsi deeply grooved on outer sides. Apex of prosternum not mar- gined. Beneath, with side pieces of meso and metathorax shallowly and sparsely punctured, the first and second abdominal segments also vaguely punctured at sides, elsewhere smooth and shining. Length, 9 mm.; breadth, 3.25 mm. Holotype, male (No. 1854, Mus. Calif. Acad. Sci.), a unique in my collection, captured by myself near Hoquiam, Washing- ton, May 27, 1914. This species belongs in the subgenus Cryohius Chaud., and is related to riparius ® and its associates fatuus and pinguedineus, 8 See my notes concerning' these in “The Coleoptera collected by the Katmai Expedition,” Nat. Geograph. Soc. Contrib. Tech. Papers, Vol. II, No. 1 (1924), p. 9. JANUARY, 1926] VAN DYKE HARPALIN^ 115 but it differs from these by having the prothorax more elon- gate, the anterior prothoracic angles more prominent, the sides posteriorly parallel for a considerable distance in front of the hind angles, the outer basal impression merged with the inner in one deep pit, not separate anteriorly as in those, the lateral margin of both prothorax and elytra more distinctly defined, the scutellar striae longer, the punctures of the striae almost obliterated, and the antennae and legs longer and more delicate. The shape of the beetle, especially that of the prothorax and elytra, strongly suggests some of the species of Bembidium like funereum and mceklini. Anilloferonia Van Dyke, new genus Body elongate, moderately flattened and parallel. Head moderate in size, somewhat constricted behind; eyes wanting; genae slightly prominent, two supra-orbital setae; frontal grooves well developed; frontal suture distinct; clypeus prolonged beyond base of mandibles; mandibles porrect, without setae in scrobes; antennae arising under a distinct frontal ridge, well developed, the three basal segments glabrous, outer segments somewhat enlarged; submentum biemargi- nate and with well-defined tooth at middle; maxillae with laciniae hooked at tip, the maxillary palpi of moderate length, the last seg- ment elongate conical, the penultimate about two-thirds length of preceding and obconical; ligula of moderate size and bisetose at tip; labial palpi with the last two segments of about equal length, the penultimate bisetose in front. Prothorax with lateral setae one-third distant from anterior angles and others within posterior angles. Body not pedunculate. Elytra narrowly indexed, margin interrupted posteriorly and with evident internal plica, disc without dorsal punc- tures. Apterous. Prosternum not prolonged at tip and not margined at apex. Mesosternum almost vertical in front and rather widely sep- arating the coxae, the epimera narrow, yet wider internally. Metas- ternum well developed, the episterna about a third longer than broad, the epimera almost one-half the width of the former; posterior coxae contiguous. Legs well developed, femorae not greatly enlarged, pos- terior trochanters large and somewhat elliptical in shape; anterior tibiae deeply emarginate within and with inner spurs at summit of emarginations. Genotype; Anilloferonia testacea Van Dyke, new species. This genus, according to the characters, should be placed in the tribe Pterostichini as constituted by Horn,® and close to the genus Pterostichus. It differs primarily from that by its having 9 “On the Genera of Carabidse, with special- reference to the fauna of Boreal America,” by George H. Horn, Trans. Am. Bnt.

Superficially, it looks like a diminutive specimen of one of the species close to angustus or like a giant Anillus, particularly as regards the shape of the head. Anilloferonia testacea Van Dyke, new species Testaceous. Head one-third longer than broad, one-third as broad as prothorax, smooth and shining; antennae extending slightly be- yond posterior thoracic angles. Prothorax about as wide as long, apex and base feebly emarginate; sides feebly arcuate for anterior half, straight and slightly convergent posteriorly; hind angles barely obtuse, lateral margin fine; disc slightly convex anteriorly, flattened in region of hind angles; median longitudinal groove distinct, yet fine and almost complete; anterior transverse impression indicated only by series of small black spots; posterior impression vague; basal impressions single, not well defined; basal area obscurely punc- tate; basal margin only faintly indicated at middle. Elytra almost a third longer than head and prothorax combined, a third longer than broad, elongate elliptical; humeri rounded; lateral margin fine; disc feebly convex, flattened at center; striae nine in number, fine yet complete, very finely and not closely punctured, the eighth with five well-marked fovese near humeri and five near apex, the seventh with one fovea near apex, the intervals flat and without punctures; scu- tellar striae wanting. Beneath smooth and shining, except side pieces of meso and metathorax and first two abdominal segments which are obscurely punctate-rugose. Length, 5.5 mm.; breadth, 2 mm. Holotype, female (No. 1855, Mus. Calif. Acad. Sci.), a unique captured by myself in the Yakima Indian Forest Re- serve on the east side of Mount Adams, Washington, at an altitude of about 4000 feet, July 1, 1925. It was found beneath an old log in the forest. This and two species of Anillus are the only completely eye- less Carabidae which have been found on the Pacific Coast. Evarthrus montanus Van Dyke, new species Elongate, robust, black, head and prothorax somewhat shining, elytra subopaque, slightly more pronounced in female. Head large, almost four-fifths breadth of prothorax; frontal grooves well marked; eyes prominent; mandibles robust and projecting; antennas extend- ing a couple of segments beyond hind angles of prothorax. Pro- thorax about 1 mm. broader than long, apex feebly emarginate, base more distinctly so and about equal in breadth to apex; sides slightly arcuate and convergent posteriorly until near hind angles where JANUARY, 1926] VAN DYKE HARPALIN^ 117 they become gradually sinuate, then straight to the angles which are well defined, slightly obtuse and blunt at apex; lateral margin well defined, rather narrow in front but gradually broader posteriorly; disc convex, with series of fine transverse rugae near middle; median longitudinal goove linear and well impressed, almost complete pos- teriorly and ending abruptly anteriorly at transverse impression; anterior transverse impression sharply defined and complete, the posterior not definable; basal impressions double, the inner deep and broad and each with a faint fovea on inner margin, the outer like- wise deep but more linear, with a fairly well-defined carina to the outer side of it. Elytra 2 mm. longer than head and prothorax com- bined, one-sixth broader than prothorax and over two-thirds longer than broad; humeri pronounced though rounded; sides moderately arcuate and distinctly but shallowly sinuate before apex, disc convex though slightly flattened toward base; striae complete, well impressed anteriorly, less so posteriorly, finely rather closely and distinctly punctured anteriorly, the punctures gradually disappearing toward apex; intervals somewhat flattened, the third with a single fovea back of middle and close to second stria, the seventh distinctly ele- vated at base; scutellar striae vaguely defined at base of second interval. Legs moderately robust, hind tarsi without lateral grooves externally. Prosternum deeply grooved and not margined at apex. Beneath moderately smooth and shining. Length, 18 mm.; breadth, 6.5 mm. Holotype, male (No. 1856), allotype, female (No. 1857, Mus. Calif. Acad. Sci.), and several paratypes in my collection, cap- tured by myself in the valley at the base of the Black Moun- tains, North Carolina, during July, 1902, I have a series of seventeen specimens. It was not uncommon, and both Mr. William Beutenmueller, my traveling companion, and I took them frequently. The females are often much broader and more robust than the males. A pair of paratypes will be deposited in the United States National Museum at Washington, D. C. This is a form that is characteristic of the mountains, I have always associated it with Evarthrus sigillatus Say, which, though found on both sides of the Alleghanies, is generally more northern in distribution. I believe that it is derived from the same common stock, but it is markedly different in appearance, even when viewed superficially, for it is considerably larger and more elongate, the prothorax especially so. The prothorax is also more flattened basally, the sides distinctly though gradu- ally sinuate posteriorly, the hind angles definitely angulated, and the basal impressions less separated. The elytra are more 118 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 elongate, more flattened basally and, as a rule, with the striae more impressed anteriorly. Evarthms vagans alabamae Van Dyke, new subspecies This name I am proposing for a very distinct phase of the species which is characterized by being of large size, 17 mm. long by 7 mm. in breadth, resembling in this regard the larger phase generally known as engelmanni, and differing from this primarily by having the sides of the prothorax evenly arcuate to hind angles, not at all sinuate posteriorly, the hind angles as a result very obtuse, the lateral margin more broadly expanded posteriorly, the basal impressions more distinctly separated, and the carinae near the hind angles short and rather poorly defined, not long and conspicuous as in the other. Holotype, male (No. 1858), allotype, female (No. 1859, Mus. Calif. Acad. Sci.), and five paratypes in my collection, all captured near Mobile, Alabama, by Mr. H. P. Loding. Two other specimens, one from Shreveport, Louisiana, and the other from Hart, Louisiana, agree with these. Evarthrus lodingi Van Dyke, new species Large, elongate, robust, black, rather shining throughout. Head two-thirds as broad as prothorax, somewhat elongate; frontal grooves deeply impressed; frontal suture distinct but fine; eyes prominent; mandibles robust, elongated. Prothorax over 1 mm. broader than long, apex feebly emarginate; base slightly narrower than apex, emarginate, narrowly margined close to angles; sides rather broadly arcuate and convergent posteriorly until close to base, where they become abruptly sinuate, then oblique to hind angles, which are well defined though rounded; lateral margin fine, uniform and well reflexed; disc moderately convex, smooth; median longitu- dinal groove fine, distinctly impressed, extending from apex to near base and with small foveate enlargement near apex and a very large and deep one near base; transverse impressions not defined; basal impressions treble, a deep foveate inner one, a deep, long linear median one, well separated from the first, and an oblique shorter linear outer one joining basally with the second, a well-defined Carina at the outer side of the last. Elytra one-fourth longer than head and prothorax combined, over 1 mm. broader than prothorax and five-twelfths longer than broad, subelliptical; humeri prominent but rounded; margin rather broad, sharp and distinctly sinuate near apex; disc moderately convex, striae complete, very deeply impressed, finer apically, very finely closely punctured, the punctures gradually obliterated toward apex; scutellar stria long, deeply impressed and within base of first interval; intervals convex, the third with fovea JANUARY, 1926] VAN DYKE HARPALIN^ 119 about one-third distant from apex, the seventh conspicuously ele- vated at base. Legs long yet robust, hind trochanters broad, flat- tened, and subacute at apex; hind tarsi without lateral grooves exter- nally. Prosternum shallowly grooved and not margined at apex. Beneath smooth and shining. Length, 20 mm.; breadth, 7.5 mm. Holotype, male (No. 1860, Mus. Calif. Acad. Sci.), in my collection, captured at Monte Sano, Madison County, Alabama, June 9-11, 1911, by Mr. H. P. Coding and by him very kindly presented to me. Other specimens are in Mr. Coding’s collec- tion. The species is named after the captor, a kind and generous friend who has done many favors for me and has contributed much toward making known the Coleopterous fauna of his region. This very distinct and elegant species should, perhaps, be placed somewhere near sodalis. It is much like a giant phase of the latter, with the hind angles of the prothorax of about the same size but more rounded. Its size, graceful form, three series of distinct basal thoracic impressions, long deep scutellar stride, deeply impressed striae and convex intervals should set it well apart from all known species. According to the Ceng catalogue and the works of Colonel Casey this species would fall in the genus Eumolops Casey, but that genus is not founded upon any character of good generic value, therefore I feel that it should not be recognized. Platynus prognathus Van Dyke, new species Elongate, subparallel, flattened, nigropiceous, margins of prothorax, elytra, basal segments of antennae, mouthparts, legs, and sides of abdomen testaceous. Head much elongated, with mandibles longer than prothorax and almost as broad; frontal impressions large, irregularly and shallowly impressed; clypeus bifoveate in front; eyes large and moderately convex; mandibles very long and sickle-shaped, as long as rest of head; antennae long, terminal segments enlarged, the last three extending beyond base of prothorax. Prothorax one- fifth broader than long; apex feebly emarginate; base transverse and equal in breadth to apex, vaguely margined, sides arcuate for anterior half, straight and oblique posteriorly, the hind angles very obtuse and rounded and in advance of the basal margin; lateral margin of moderate width, slightly reflexed and with broad, shallow fossae within posteriorly; disc slightly convex; median longitudinal groove distinctly impressed, the anterior transverse impression short but 10 “Memoirs on the Coleoptera,” by Thomas L. Casey, Vol. VIII (1918), p. 351. 120 THE PAN-PACIFIC ENTOMOLOGIST [VOL, II, NO. 3 deep, the posterior vague, the surface finely transversely rugose. Elytra over a third longer than head and prothorax combined, one- third broader than prothorax, over twice as long as broad, elongate elliptical; humeri well rounded; sides almost parallel, deeply sinuate posteriorly, the margin fine; disc quite flattened, striae complete, deeply impressed, punctures very fine and obscure, intervals flat- tened, the second, fifth, and seventh somewhat broader; the narrower subconvex third with three punctures near the second stria, the anterior about at middle; scutellar stria rather long and well im- pressed. Legs of moderate length. Beneath rather smooth and shining. Holotype, female (No. 1861, Mus. Calif. Acad. Sci.), in my collection, captured on St. Simon Island, Okefinokee Swamp, Georgia, April 27 to May 12, 1911, by Professor J. C. Bradley, and by him very kindly presented to me. This anomalous species might be placed in the group with cincticollis, but is widely separated from that, as well as from all of our other species. Its elongate, parallel form, very long mandibles and somewhat clubbed antennae give it an appear- ance all its own. Though this species would be classed as an Anchomenus, I consider that as but a subgenus at most of Platynus, in this regard following such able students of the Carabidae as Ganglbauer and Le Conte and Horn. Colpodes rufiventris Van Dyke, new species Moderately elongate, head and prothorax decidedly narrowed, flat- tened, nigropiceous, elytra somewhat darker, antennae, mouthparts, legs, undersurface, and margins of elytra rufous with a slight piceous tinge; head and prothorax shining, elytra subopaque. Head about 1 mm. less in breadth than prothorax and about three-fifths as broad as long; frontal grooves fine; front flattened at outer side of grooves; eyes of but moderate size; mandibles long and prominent; antennae long and delicate, extending almost to middle of elytra; submentum with simple tooth. Prothorax slightly broader than long, about one- half the breadth of elytra; apex slightly emarginate; frontal angles not prominent; base feebly arcuate, vaguely margined; sides evenly but shallowly arcuate from apex to base, the hind angles broadly rounded, the margin narrow, broader posteriorly and slightly re- flexed; disc convex, with vague but fine transverse rugae; longitu- dinal groove finely but distinctly impressed; anterior transverse im- pression well, though not sharply, impressed, the basal a shallow sulcus. Elytra a third longer than head and prothorax combined, a third longer than broad, elongate ovate, broadest back of middle; base deeply emarginate, the humeri as a result prominent, subangu- 11 ‘‘Die Kafer von Mitteleuropa,” by Ludwig Ganglbauer, Vol. I, p. 248. JANUARY, 1926] VAN DYKE HARPALIN^ 121 late; lateral margin narrow in front, broader posteriorly; apices rounded; disc slightly convex, striae finely impressed, without dis- tinct punctures; scutellar stria very long; intervals flat, the third with an anterior very vague puncture near third stria, a vague punc- ture near second stria at middle and an evident puncture near second stria not far from apex. Legs rather long and delicate; anterior tibiae shallowly grooved on outer face, middle and posterior deeply grooved on both outer and inner face posteriorly, with caring be- tween; first and second segments of front tarsi shallowly grooved on both sides above; first three segments of middle and hind tarsi rather deeply grooved on both sides above; fourth segment of all tarsi narrowly bilobed posteriorly, with a slight tuft of pubescence beneath. Beneath rather smooth and shining. Length, 10.5 mm.; breadth, 4 mm. Holotype, male (No. 1862, Mus. Calif. Acad. Sci.), in my collection, captured at an altitude of 6000 feet on Mount Washington, near Nogales, Arizona, July 10, 1919, by Mr. J. Aug. Kusche, and by him kindly presented to me. This, the second species of Colpodes to be described from our fauna, differs from Colpodes longiceps Schfr., also from Arizona, markedly in color as in other features. It does not agree either with the descriptions of any of the known Mexi- can species. Except for the rather wide margin of the pro- thorax, this species might fall in the genus Glyptolenus Bates, because of the tibial and tarsal characters, but these are quite variable within the genus Colpodes, therefore not reliable for establishing a group of more than subgeneric rank at most. The genus Colpodes is sometimes placed as but a subgenus of Platynus, but I think that though the character used for its separation, the deeply emarginate or bilobed fourth tarsal seg- ment, is not a very marked one ; it is sufficiently definite, espe- cially when taken in connection with other characters and backed by the fact that the genus as a whole is more or less arboreal and generally restricted to the warmer parts of the world, whereas almost all of Platynus are strictly terrestrial and confined to the temperate regions. Pseudaptinus oviceps. Van Dyke, new species Elongate, depressed, pubescent, rufotestaceous, antennae, palpi, and legs testaceous. Head elongate oval, one-fourth longer than broad and three-fourths as broad as prothorax; finely sparsely punctate, rather shining; frontal impressions well marked, rather broad; eyes small, but slightly convex and hardly projecting beyond the even 122 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 curve of the side of the head; mandibles prominent, prognathous; antennae long and slender, extending several segments beyond the base of the prothorax. Prothorax a little longer than wide, broadest near apex; apex very shallowly emarginate; base slightly arcuate, about one-half breadth of widest portion; sides broadly rounded near anterior angles, oblique and convergent to posterior third, then sub- parallel to hind angles which are right-angled but not prominent; disc moderately convex, somewhat coarsely and sparsely punctured; median longitudinal groove distinctly impressed; anterior transverse impression well defined, posterior vague; basal impressions long and shallow. Elytra oblong elongate, humeri broadly rounded, apex trun- cate, outer angles rounded, disc flattened; striae finely impressed, complete; intervals flat, finely and densely punctured, somewhat rugose toward base. Legs long and delicate. Prosternum sparsely and coarsely punctured, smooth at sides, meso and metapleurae coarsely closely punctured, the abdomen very finely punctured. Length, 6 mm.; breadth, 2 mm. Holotype, female (No. 1863, Mus. Calif. Acad. Sci.), in my collection, captured by myself about 1889, under a stone near the Los Angeles River, California, in what is now Griffith Park. This species in size and general appearance looks very much like Pseudaptinus tenuicollis (Lee.), but its ovate and nar- rower head, small eyes, and prominent mandibles separate it very decidedly from that as well as from Pseudaptinus lecontei (Dej,). Thalpius microcephalus Van Dyke, new species Elongate, depressed, pubescent, rufotestaceous, antennae, palpi, and legs testaceous. Head elongate, one-fourth longer than broad and narrower than prothorax, moderately coarsely, sparsely punctured, somewhat shining; frontal impressions shallow, poorly defined; eyes rather small, not projecting laterally beyond sides of head; mandi- bles of usual size; antennae of moderate length, extending somewhat beyond base of prothorax, segments four to ten oblong. Prothorax about as long as wide, broadest one-third distance from apex; apex slightly emarginate, anterior angles projecting forward somewhat (much more evident than in horn't) ; base pedunculate as usual; sides shallowly arcuate anteriorly, oblique and sinuate posteriorly, hind angles acute; disc slightly convex, flattened medially, coarsely, mod- erately closely punctured; median longitudinal groove sharply im- pressed; anterior transverse impression well defined, posterior vaguely marked; basal impressions of moderate length, shallow. Elytra ob- long, elongate; humeri broadly rounded; apex truncate, outer angles rounded; disc flattened; striae shallowly impressed, not distinctly defined, especially posteriorly; intervals flat, rather coarsely and irregularly punctured. Legs moderately long. Body beneath coarsely, JANUARY, 1926] VAN DYKE HARPALIN^ 123 rather regularly punctured anteriorly, abdomen more finely punc- tured. Length 4.75 mm.; breadth, 1.75 mm. Holotype, a unique female (No. 1864, Mus. Calif. Acad. Sci.), in my collection, secured by myself from beneath a stone on the hills in Griffith Park, Los Angeles, California, January 12, 1912. This species has the same general body proportions as Thal- pius horni Chd., but it is much smaller. Its narrow head, less prominent eyes and poorly defined elytral striae also serve to distinguish it from that as from all other species. In color, it resembles rufulus, but it is smaller and has a narrower pro- thorax in addition to the characters just mentioned. In this connection I wish to state that in Southeastern Cali- fornia specimens of Thalpius horni Chd., which are entirely rufous, are not uncommon. Harpalus washingtoniensis Van Dyke, new species Robust, black or slightly brownish. Elytra piceous brown, an- tennae, mouthparts and legs piceotestaceous, tarsi darker, very shin- ing, elytra of females duller. Head large, over two-thirds breadth of prothorax, smooth and shining; frontal suture deeply impressed; eyes moderately prominent; mandibles well developed; antennae reaching to hind angles of prothorax. Prothorax almost a third broader than long; apex and base slightly emarginate, the latter as broad as apex and distinctly and completely margined; sides moder- ately and evenly arcuate from anterior angles to posterior fourth, then sinuate and convergent to hind angles, which are obtuse, almost right-angled, and sharp at apex; lateral margin fine; disc convex, median longitudinal groove distinctly impressed; anterior transverse impression distinct, posterior vague, basal impressions deep; surface smooth and shining, basal area irregularly punctured, more definitely so in and about basal impressions. Elytra over one-fifth longer than head and prothorax combined, two-fifths longer than broad; humeri rounded; sides slightly arcuate, markedly excised near apex, margin fine; disc decidedly convex, strise well impressed; scutellar stria rather long; intervals flattened, somewhat convex basally in males. Legs robust. Beneath finely, sparsely and rather indistinctly punc- tured in front, the abdomen smooth and shining, except for sides of first and base of second segment which are slightly punctured. Length, 8.5 mm,; breadth, 3.25 mm. Holotype, male (No. 1865), allotype, female (No. 1866, Mus. Calif. Acad. Sci.), and numerous paratypes in my collection, captured by myself at Port Angeles, Washington, May 26, 1907. In my series of thirty-two mounted specimens, I have 124 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 them from the following additional localities : Nanaimo, British Columbia ; Monroe, Lake Quiniault, Seattle, The Forks, North- bend, and Orcus Island, Washington ; and Marshfield, Oregon. A pair of paratypes will be deposited in the entomological collection of the U. S. National Museum, Washington, D. C. This species varies considerably in size, ranging in length from 7 to 10 mm., the females are, as a rule, larger than the males, and somewhat paler in color, the epipleurae often lighter, while in a few cases the legs are quite piceous. It belongs in association with Harpalus spadiceus Dej. and Harpalus carolincB Schaeffer, differing primarily from the former by having the prothorax more sinuate posteriorly and the hind angles almost right and sharply defined, and from the latter by having the legs yellowish or testaceous, the general body color, especially the elytra, more brownish, the basal impressions of the pro- thorax more broadly impressed, the basal area itself definitely punctate, the elytral margin more acutely excised posteriorly, and by being as a whole somewhat smaller and less elongate. Harpalus martini Van Dyke, new species Robust, elongate, subparallel, black, antennae, tibiae, and tarsi some- what piceotestaceous, very shining above in the male, the female quite opaque. Head large, two-thirds breadth of prothorax; frontal suture very fine, not impressed; eyes moderately prominent; mandi- bles well developed; antennae reaching to hind angles of prothorax. Prothorax over a third broader than long; apex distinctly emargi- nate, the anterior angles slightly prominent; base also distinctly emarginate, completely margined and broader than apex; sides very shallowly arcuate, almost subparallel from anterior angles to pos- terior fourth, thence sinuate and divergent to posterior angles, which are almost right-angled and slightly rounded at apex; lateral margin fine; disc convex, median longitudinal groove very fine, anterior and posterior transverse impressions both vague, basal impressions broadly and shallowly impressed; posterior angles much flattened; basal area irregularly punctured, especially about basal impressions. Elytra one-fifth longer than head and prothorax combined and one- fifth longer than broad; humeral angles distinctly dentate; sides slightly arcuate, almost parallel, shallowly excised near apex, margin fine; disc convex, striae finely impressed; scutellar stria rather long; intervals flat. Legs robust. Under surface subopaque anteriorly; abdomen posteriorly smooth and shining in male, subopaque in female; an oblique area on second and third abdominal segments, immediately beneath hind femora, finely punctate and with short hairs arising from each puncture. Length, 10 mm.; breadth, 3.75 mm. JANUARY, 1926] VAN DYKE HARPALINiE 125 Holotype, male (No. 1867), and allotype, female (No. 1868, Mus. Calif. Acad. Sci.), collected at Bear Lake, San Bernar« dino Mountains, California, May 5, 1919, by Mr. J. O. Martin, and kindly presented to me. Four paratypes are in Mr. Martin’s collection. This species is named after Mr. Martin, an excellent collector, in consideration of many favors. The species is probably related to Harpalus somnulentus Dej., but is decidedly darker. Its color and general shape also sug- gest Harpalus cautus Dej. Its peculiarly shaped prothorax, with base broader than apex, sides subparallel, sinuate and divergent posteriorly, and the well-marked humeral dentations of the elytra should, however, readily serve to separate it from the above and from all of our other species. Dicheirus blaisdelli Van Dyke, new species Robust, very convex; head and prothorax rufo-piceous, elytra black, legs rufous; clothed above with long erect hair, the sternal and midventral region as well as the legs also very pilose, the hair in the main shorter than above. Head very coarsely, moderately densely and closely punctured, antennas about reaching hind angles of prothorax. Prothorax distinctly broader than long, 3.5 mm. by 3 mm., emarginate at apex, transverse at base, the latter 2.5 mm. wide, sides broadly rounded in front, straight and convergent pos- teriorly, just perceptibly sinuate in front of hind angles, the hind angles obtuse and distinct, not rounded, the disc convex, coarsely deeply and rather sparsely punctured. Elytra over one-third longer than broad, .5 mm. broader than prothorax, sides hardly arcuate, evenly rounded at apex, posterior sinuation faint; disc very convex, striae distinctly impressed, impunctate, intervals flat and shining, sparsely irregularly biseriately" punctured, deeper toward base, very finely near apex. Prosternum coarsely moderately closely punctured, propleurae finely sparsely and rather indistinctly punctured, the meso- and meta-pleurae more distinctly punctured and somewhat rugose, the abdomen finely and closely punctured at middle in front, very finely and sparsely at middle behind, with sides impunctate. Legs robust, spines of anterior tibiae trifid, of posterior slender and acute. Length, 11 mm.; breadth, 4 mm. Holotype female (No. 1869, Mus. Calif. Acad. Sci.), and three paratype females in the collection of Dr. F. E. Blais- dell, captured by Dr. Blaisdell at Poway, San Diego County, California. This robust species in both structure and appearance stands midway between Dicheirus strenuus (Horn) and Dicheirus an- gularis Casey. It is separated from the former by being smaller 126 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 and by having the propleurse somewhat punctured and from the latter by being far more convex and robust, as well as by having the hind angles of the prothorax more obtuse. From dilatatus, it can always be separated not only by its robustness, but by having non-rounded hind angles to prothorax and by having longer pile. The elytra of blaisdelli simulate very closely those of a female Plastocerus agassisi Lee. The genus Dichei- rus Mann, is one of the few which might, with benefit, be kept separate from the genus Anisodactylus Dej. Habits- of Trachykele nimbosa Fall While on Mt. Hood, Oregon, during the latter part of June, I noticed that the rare buprestid, Trachykele nimbosa Fall, could often be found ovipositing in the blazes made by the surveyors in fir trees, Abies, along the right-of-way for a forest road. These beetles are rather silent in flight, as is the case with the AcmcBodera, and as a result they alight without attract- ing much attention. Unfortunately, they also depart with as great ease, simply vanish before you. This is particularly the case during the heat of the day. If the weather becomes cooler while they are in evidence, they may readily be approached and even picked up with the fingers. Trachykele opulenta Fall, a brilliant green species, which breeds normally in the native cypress, Cupressus sar genii Jep- son, on Cypress Ridge, Marin County, California, has been found this last year to have come down into the valleys and attacked the planted Monterey cypress, Cupressus macrocarpa Hartw. As pointed out by Dr. H. E. Burke, this species only attacks the dead limbs of living trees, the larvae gradually work- ing into the main trunk of the tree which they in time honey- comb. — E. C. Van Dyke. Habits of Cymatodera decipiens Fall During the summer of 1925, several Cymatodera dicipiens Fall emerged from twigs of Pinus ponderosa collected during the winter of 1923 on Mt. Wilson, Los Angeles County, California. During the spring and summer of 1924 and 1925, the only other insects to emerge from these twigs were an undes- cribed species of Carphoborus which came out in some numbers. It seems from this that the latter insect, in the larval stage, is preyed upon by the Cymatodera larvae. — Alonzo C. Davis. JANUARY, 1926] FALL ALASKAN COLEOPTERA 127 A LIST OF THE COLEOPTERA TAKEN IN ALASKA AND ADJACENT PARTS OF THE YUKON TERRITORY IN THE SUMMER OF 1924 BY H. C. FALL Tyngshoro, Massachusetts It was the writer’s privilege to be one of a party of three to make a trip to this wonderland of the North during the summer of 1924. While the excursion was primarily one of sight-seeing and general recreation, the writer, from long habit, kept always an eye open for possible coleopterous windfalls, and as opportunity offered, a few minutes, a few hours, or even the better portion of a day in places where a long enough stop permitted, were devoted to special search for beetles. The results in the aggregate seem worthy of record, in view of the general interest taken in collections from this somewhat remote region. In 1857 Le Conte remarked that at the close of the activities of the Russian entomologists, the fauna of the region explored by them was more completely developed than that of any other part of the continent. This, of course, is no longer true, even if we confine ourselves to the coast region in which most of the early collecting was done; while if the entire territory of Alaska be considered, it would perhaps be nearer the truth to say that its fauna is less completely known than that of any other equal area of our country. The total number of species of Coleoptera listed from Rus- sian America at the time of Mannerheim’s last supplement in 1853 was 540. Hamilton’s Alaskan list with supplement in 1894 enumerates 578 species, and the few scattering additions since that time can hardly bring the total much, if any, above 600 species. It is quite probable that there are now in collec- tions, notably that of the National Museum, a considerable number of additional species, but these, even if worked up, have not yet been recorded. On the present trip, as nearly as can now be determined, 448 species were taken within, or adjacent to, the Alaskan boundary, of which 117, exclusive of unidentified Stenus and Aleocharini, appear to be new to the Alaskan list. Of these, 61 occurred in the coast region and 64 in the Yukon Valley, 128 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 8 species being common to both regions. The fact that nearly half of these 117 species are from the well-explored coast region is rather surprising, since it was to be expected that the great majority of future additions to the Alaskan fauna would be from the interior valleys and mountains, which, eiito- mologically speaking, are relatively unworked. The disparity in this case would indeed have been much greater if the numer- ous species taken at Dawson, Y. T., where considerable collect- ing was done, had been included, for it is practically certain that a very large proportion of the species occurring at this point must also occur across the international boundary only fifty miles distant, where the topographical and climatic condi- tions along the Yukon are virtually the same. In the interest of economy of space, I shall not attempt here to speak of collecting conditions and experiences, or, except for the table of dates below, to give the itinerary of the trip, further than to say that we left Tyngsboro, Massachusetts, on June 5, via Montreal and the Canadian Pacific, arriving at Skagway June 18, after making the incomparable trip up the “Inside Passage” from Vancouver. On August 2 we boarded the steamer at Ketchikan for Prince Rupert, the return jour- ney across the continent being made thence via the Canadian National Railway to Montreal, arriving at Tyngsboro August 10. The principal dates on which collecting was done are given once for all in the subjoined table: Wrangel, Alaska, June 17. Anchorage, Alaska, July 10-14. Skagway, Alaska, June 18-20.

A single example; also taken by me at Jasper Park, Alberta, on the return trip. Nebria metallica Fisch, Skagway; Seward; Child’s Glacier; Sitka; Juneau. Nebria sahlbergi Fisch. Seward; Juneau. Two forms refer- able to this species were taken on the trip ; one of narrow thorax and somewhat more elongate form at Juneau and Seward is probably the true sahlbergi. Of this a variety with violaceous elytra (probably violaceus Mots.) and an- 130 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 other with pale legs occurred. The other form is repre- sented by a single example taken at Coldstream, Vancouver Island ; it is a little stouter with broader thorax, agreeing closely with specimens in my collection from Washington State and the Rocky Mountains of New Mexico. This form, in its broader thorax, approaches moesta Lee., which, I think, can hardly be a varietal form of sahlhergi, although so recorded in the books. Nebria bifaria Mann. A single typical specimen with bicolored legs was taken at McKinley -Park. Nebria gebleri Dej. Juneau. Nebria viridis Horn. Dawson; Yukon River (Sheep Creek below Eagle) ; Tanana River.

Slightly smaller than, but of the general form and aspect of, integer Lee., near which it must be placed. Body black, bronzed; legs and antennae black. Head four-fifths as wide as the prothorax; front feebly transversely impressed; epis- toma broadly and deeply emarginate. Prothorax subglobose, slightly wider than long, sides broadly, evenly arcuate. Elytra oblong-oval, three-fifths longer than wide; striae entire, rather deeply impressed and strongly punctured before the middle, becoming much finer and more finely punctured on the declivity; eighth stria finely impressed, distinctly punctate throughout; base not margined; third interspace tripunctate, a single apical setigerous puncture. Basal joint of hind tarsi twice as long as wide and evidently shorter than the two following combined. Length, 2.5 to 2.75 mm.; width, .8 to .85 mm. Anchorage, Alaska, seven examples, all taken in damp moss on low ground, July 13-14, 1924. In integer, with which the present species is compared, the size is slightly larger, the legs and antennae are never really black, but rather dark rufous to rufopiceous, the basal joint of the hind tarsus is more elongate, at least three times as long as wide and fully as long as the two following; apex of elytra with two setigerous punctures. There is a strong probability that integer is distinct from the European ceneus with which it has been united, judging from two examples of the latter sent me by Mr. Edmund Reitter. In nigriceps, with which the present species might also be compared, the size is larger, the JANUARY, 1926] FALL ALASKAN COLEOPTERA 131 elytra more finely striate and punctate, the eighth stria obso- lete, and the elytral apex apparently with two setigerous punc- tures ; the basal joint of the hind tarsus is also more elongate, as in integer. Only two species of Dyschirius have hitherto been recorded from Alaska, viz., the frigidus and transmarinus of Manner- heim. The former was described from the Keiiai Peninsula, and my Anchorage species might well be expected to be the same. I find, however, that my specimens do not fit the descrip- tion very well, the size of frigidus (3.5 mm.) being materially larger, while the el 3 dra are said to be scarcely wider than the thorax and the elytral striae evanescent shortly behind the middle. If frigidus really equals ceneus, as it stands in our lists, it certainly is different from the Anchorage species. Trans- marinus was described from a single example from Sitka; it is even larger than frigidus. Asaphidion yukonense Wickh. White Horse; Dawson. Bembidion simplex Haywd. McKinley Park.

Bembidion quadrifoveolatum Mann. Kasaan. Bembidion yukonum Fall, n. sp. Form and size about as in grapi, but rather larger and a little stouter. Black, distinctly green-bronzed, antennae at base and legs rufous; surface above strongly shining throughout, without alutace- ous sculpture except very feebly at elytral apex. Antennas scarcely attaining the middle of the length, intermediate joints about two and a half times as long as wide. Head a little wider than the thoracic apex; eyes moderate. Prothorax subcordiform, one-fifth wider than long, base slightly narrower than apex; sides strongly evenly rounded from apex to basal constriction, which is parallel-sided for a distance about equal to one-fifth the basal width; base angles sharply rec- tangular, evidently but not very strongly carinate; basal impressions deep, with a few rather coarse punctures. Elytra one-half wider and three times as long as the thorax, one-half longer than wide; sides broadly arcuate, humeri well marked, not angulate; striae feebly im- pressed near the suture; strial punctures moderate, becoming finer posteriorly, very fine but traceable near the apex; those of seventh stria very fine in apical half; intervals flat, the third with two setiger- 132 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 ous punctures adjacent to the third stria at approximately the basal and apical thirds. Length, 4.75 mm.; width, 1.9 mm. Described from a single male specimen taken by the writer at Dawson, Yukon Territory, June 30, 1924. This species belongs to the ustulatum group, and is appar- ently nearest insopitum Csy. The latter is unknown to me, but according to description is a considerably larger species with more transverse thorax, deeply striate elytra, the seventh stria less distinctly punctured basally. Grapi is a rather smaller and narrower species, with much finer elytral sculpture, the legs typically black, though in two Greenland examples in the Le Conte collection and in many North American examples so referred, they are more or less distinctly rufous. Bembidion bimaculatum Kby. Skagway; Dawson; Nenana. There occurred at Nenana, together with the typical form, what I take to be a variety of this species with smaller thorax, browner elytra with or without apical spot, and finer striae. *Bembidion mckinleyi Fall, n. sp. Black, above with feeble deep-green surface luster, beneath black, femora piceous; trochanters, tibiae, and tarsi reddish-brown. Upper surface polished throughout, with faint traces of alutaceous sculp- ture only at elytral apex. Antennae black, basal joint rufescent, about half as long as the body, slender, intermediate joints not quite three times as long as wide. Head three-fourths as wide as thorax, eyes not at all prominent. Prothorax nearly one-third wider than long, sides rounded anteriorly, sinuate posteriorly, becoming nearly parallel in basal fifth or sixth; hind angles rectangular, side margins very finely reflexed; disc convex, median line well impressed and nearly entire; foveae only moderately deep, flat or slightly tumid at bottom, with a few obsolete punctures, hind angles not distinctly carinate. Elytra fully three and one-half times as long and three-fourths wider than thorax, three-fifths longer than wide, humeri rather wide, nar- rowly rounded, sides diverging slightly and nearly straight in basal two-fifths, greatest width at or very slightly behind the middle; striae finely impressed, moderately strongly and closely punctured basally, more feebly so posteriorly, nearly disappearing at apex; seventh stria represented by a few fine punctures near the base. Length, 5.5 mm.; width, 2.25 mm. Described from a single pair taken in McKinley Park, Alaska, July 8-12, 1924, by my fellow-traveler, Mr. C. A. Richmond. This species belongs to the ustulatum group, and by its nar- row thorax is somewhat remindful of scopulinum. It is, how- JANUARY, 1926] FALL ^ALASKAN COLEOPTERA 133 ever, much larger and without maculation. Careful measure- ment shows that the prothorax is not quite as wide at apex as at base. On this basis it would, by Hayward’s table, be asso- ciated with nevadense and consanguineum, to neither of which is it at all similar. By Casey’s table it would fall near hum- holdtense, which is even more remotely related. If the thorax were regarded as narrower at base than at apex (this relation is at best a rather elusive one) it would fall between scopulinum and canadense in Hayward’s table, which is perhaps the most satisfactory position for it. Bembidion rupicola Kby. (lucidum Lee.). Skagway; Yukon and Tanana Rivers. Rupicola has long stood on our lists as a synonym of ustulatum, but wrongly so. The synonomy here announced is made certain b)'^ an examination of one of Kirby’s cotypes kindly sent me by Mr. Arrow. Bembidion scopulinum Kby. Anchorage; Dawson. Bembidion picipes Kby. {grapi Auct.). Skagway; Dawson; Yukon River (Sheep Creek, below Eagle) ; Tanana River; McKinley Park. This is the species we are accustomed to call grapi, and probably correctly so, although I have not been able to compare with European specimens. Except for darker legs, a Sheep Creek specimen is almost an exact counterpart of one of the cotypes of Kirby’s picipes, which I have had the privilege of examining. There can be no doubt that the other examples taken are the same thing, and that the species long standing as picipes on our lists, following Le Conte’s misinterpretation, must henceforth be known as plagiatum Zimm. Bembidion dentellum Thumb, (incrematum Lee., arcuatum Lee.). Dawson. "^Bembidion coloradense Haywd. Anchorage. Bembidion nigripes Kby. Skagway; Dawson. Bembidion intermedium Kby.

This is the true intermedium of Kirby, which seems never to have been correctly inter- preted by our systematists. It is very closely allied to nigripes (perhaps not distinct), and is similarly brightly variegated with yellow. The much less ornate intermedium 134 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 of the Hayward monograph is an entirely different thing, for which Le Conte’s name rapidum must be restored, unless on investigation some still older name comes to light. Bembidion convexulum Haywd. Dawson. Two examples. Bembidion atrolucens Csy. White Horse. Bembidion versicolor Lee. Wrangel. Bembidion dubitans Lee. Dawson. Bembidion mutatum G. & H. Dawson. ^Bembidion sulcatum Lee. Anchorage. A single example. ^Bembidion concurrens Fall, n. sp. Body oblong, suboval, rather strongly convex; black, polished throughout, elytra with a small nubilous external pale spot at apical fourth, the apex barely visibly pallescent. Antennae black, basal joint rufescent; median joints twice as long as wide. Head only slightly narrower than thorax; eyes rather large and prominent. Pro thorax one-half wider than long, apex evidently wider than base, sides broadly arcuate in front, posteriorly sinuate and subparallel in about the basal sixth, the angles sharp and just visibly more than right; basal fovese deep, not evidently punctured, bordered externally by a fine acute carina. Elytra not quite one-half longer than wide, five- eighths wider than thorax, parallel, sides feebly arcuate in basal half; striae finely impressed internally, scarcely at all so in outer half; strial punctures moderate, becoming much finer but still quite dis- tinct on the declivity and laterally in apical half. Legs very nearly black. Length, 3.25 mm.; width, 1.35 mm. Alaska. Scow Bay (north of Wrangel) two males ; Skag- way, one female. The type is a male from Scow Bay. This species belongs to the as simile group and in form most nearly resembles anguliferum, though materially smaller and with elytra much less finely punctate-striate. The species of this group form a difficult study, and are considerably more numerous than indicated by Hayward’s very conservative treat- ment. The present species by a rigorous interpretation of Casey’s table would fall near invidiosum, in which, as in cautum, the elytra are not truly black (as they are in the present spe- cies) and the legs are rufous. The el3d;ra are also relatively shorter and more coarsely striate than in concurrens. It is pos- sible that invidiosum is not really distinct from cautum, and I feel tolerably sure that digressum Csy. is the same as con- nivens Lee. Bembidion sp. dub. (assimile group). Dawson; Seward.

Head not quite two-thirds as wide as prothorax. Pro- thorax not quite one-half wider than long, base very slightly wider than apex; sides broadly, evenly rounded anteriorly, briefly sinuate before the nearly rectangular hind angles; disc moderately convex, anterior transverse impressed line feeble; median line distinct, abbre- viated at both ends; disc in front completely devoid of punctures, basal impressions deep, a little oblique, numerously punctate; hind angles obtusely carinate; base at middle impunctate, side margins narrowly, finely punctured. Elytra ( 6 ) about one-fifth wider and not quite three times as long as the thorax and about three-fifths longer than wide; finely striate, striae finely but distinctly punctate, obso- letely so near apex.

Described from six examples taken by the writer at Skagway, Alaska, June 18-21, 1924. This species is, by a strict interpretation of Hayward’s table, to be associated with infausta Lec., and is undoubtedly closely allied with both that species and eschscholtzi, from both of which it seems constantly separable by the total lack of anterior discal punctuation of the thorax. It seems highly probable that we have too many described species already in this genus, never- theless I am unable to attach any of the published names to the present species. Amara littoralis Esch.

Antennae and trophi ferruginous, the former scarcely passing the hind angles of the thorax, their intermediate joints fully twice as long as wide; head not quite three-fourths as wide as thorax; eyes moderately promi- nent. Prothorax slightly more than one-half wider than long; base JANUARY, 1926] FALL ALASKAN COLEOPTERA 137 a little wider than apex; sides subevenly arcuate, a little more strongly so in front; basal angles obtuse, their apices somewhat blunted but not distinctly rounded; basal foveae rather strongly, closely punctured, the adjoining surface externally sparsely punc- tured, the punctures nearly absent at middle of base; sides strongly convexly declivous anteriorly, narrowly and feebly deplanate pos- teriorly from the middle, the marginal bead translucent posteriorly. Elytra not quite one-half longer than wide, sides parallel; striae fine, intervals flat with scattered, very minute punctures. Body beneath black, the epipleura not at all paler. Legs rather stout; femora and tips of tibiae black; tibiae except at apex and tarsi rufous. Length, 8.5 mm.; width, 3.5 mm. Ketchikan, Alaska, a single male (type) ; Scow Bay, one female ; Skagway, one male doubtfully referred. This species in its typical form agrees nearly with the de- scription of fugitans Csy. in many respects, including the color of the legs, but in that species the form is said to be unusually depressed, the hind angles of the thorax nearly right, and the pronotal foveae very shallow and sparsely punctured, none of which statements are at all applicable to the present species. The Scow Bay and Skagway specimens differ from the type in having the legs predominently rufous, the tips of the femora and tibiae only being lightly infuscated, the sides of the thorax are also less rounded. In the Scow Bay female the elytra are dull. All three specimens have the mentum emargination vir- tually without a tooth, although there is an extremely feeble, broadly rounded, prominence detectable on close scrutiny. Harpalus rufimanus Lee.

Elongate oval, widest at middle of the length, sides of thorax nearly continuous with those of the elytra. Head and thorax flavo- testaceous, the former with a dark spot adjacent to each eye and the hind margin narrowly blackish, the latter with the anterior mar- gin narrowly dark, and a small central spot which is diffusely pro- duced to the hind margin. Elytra with the disc broadly fuscoluteous, due to the diffusion of the customary markings, which are, however, somewhat defined when the elytra are viewed very obliquely in the direction of their length. Body beneath black except the head, thorax, and epipleura; legs rufotestaceous; tarsi blackish. Head 138 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 alutaceous and sparsely punctulate. Prothorax and elytra polished throughout, the former finely and sparsely punctured on the disc, more closely toward all the margins, more strongly so post-medially; elytral punctures nearly equal in the posterior half where they are separated by about half their own diameters, in the anterior half they are obviously, though not very conspicuously, unequal and somewhat less closely placed. Prothorax one-half wider than the head, the sides moderately divergent and almost straight throughout. Elytra twice as wide as the head and one-half longer than wide. Sides of coxal plates and of the abdomen basally, coarsely closely punctate, the punctures separated by much less than their own diameters; surface of coxal plates strongly alutaceous. Male. Four anterior tarsi strongly dilated, the second joint of the protarsus visibly wider than the first and as wide as the tibiae at apex; anterior protarsal claw a little thicker and just visibly shorter than the posterior and more strongly curved basally. Length, 3.7 mm.; width, 1.85 mm. Dawson, Yukon Territory. A single male taken by the writer June 30, 1924. This species is very closely allied to patruelis, and is possibly only a variety thereof. It differs from all specimens of a numerous series of patruelis in my collection by the almost per- fectly straight sides of the prothorax and by the strongly aluta- ceous coxal plates, these being polished and without alutaceous sculpture, except in the dull females, in patruelis. The punctua- tion of the coxal plates in patruelis is also less dense than in the present species, the elytral disc is more uniformly punctured, and the tarsi only rarely show any tendency to infuscation.

Moderately elongate, oval; upper surface pale testaceous with blackish markings as follows: JANUARY, 1926] FALL ALASKAN COLEOPTERA 139 Head with a subtriangular spot each side adjacent to the eyes, these spots confluent with each other and with a posterior marginal line at the middle of the occiput; prothorax with a small transverse spot each side of the middle in the posterior transverse impression and another still smaller at the middle of the sublateral longitudinal im- pression; elytra each with six narrow discal vitte and two or three exterior longitudinal dashes, the black vittae a little wider than the pale stripes between them. Prothorax wider at base, twice as wide as long, and about one-half wider than the head; sides oblique and nearly straight from the base almost to the apical angles; side mar- gins fine but distinct. Elytra about four and one-half times as long, and one-half wider than the thorax, and a little less than one-half longer than wide; sides markedly discontinuous with those of the thorax, subparallel and broadly arcuate in basal three-fifths; feebly sinuate before the apex in the male, obtusely angulate before an apical sinus in the female; the sutural angles acute and well defined in both sexes. Upper surface throughout micro-reticulate and sparsely, finely punctulate. Body beneath black, similarly micro-reticulate and sparsely punctulate; margins of hypomera and epipleura testaceous. Antennae and legs testaceous, the apical parts of the terminal joints of the palpi and outer joints of the antennae and the basal two-thirds of the femora infuscate. In the male the protarsi are a little wider than in the female, with the second joint evidently wider than the first (scarcely wider than the first in the female), and the protarsal claws slightly less slender, though mutually equal and scarcely longer than in the female. The last ventral segment is not appreciably modified in either sex. Length (type male), 4.5 mm.; width, 2.3 mm. Described from a single pair taken by the writer at Dawson, Yukon Territory, June 24, 1924. This species is very nearly allied to semiclarus, and may prove to be only a smaller Northern race of that species. The two agree in having the male protarsal claws slightly thickened, but the present species, in addition to the smaller size, differs in its somewhat smaller thorax with nearly straight converg- ing sides, the sides being much more rounded in semiclarus ; 12-lineatus differs from both by the protarsal claws of the male not at all thickened, the entirely pale femora and the more ample prothorax with sides less strongly discontinuous with those of the elytra. '^'Hydroporus alaskanus Fall, n. sp. Similar to the preceding species in color, markings, general form and structural features, except as follows: Form a little more elon- gate, more than twice as long as wide (less than twice as long as wide in yukonensis). Head three-fourths as wide as the prothorax, the latter with sides straight and parallel in basal half to three- 140 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 fourths, extremely finely margined; hind angles rectangular; disc with two anterior transverse black dashes parallel with those in the posterior depression; elytra with sides even more strongly discon- tinuous with those of the thorax. In the male the protarsi are as in yukonensis, except that the tarsal claws are virtually as slender as in the female; the last ventral is broadly transversely impressed medi- ally, the apical half flattened or feebly impressed longitudinally at middle. In the female the apex of the last ventral is produced in the form of a short broad deflexed process with converging sides and broadly truncate extremity. Length, 4.5 to 5.3 mm.; width, 1.9 to 2.4 mm. Ratios of length to width in four measured examples are 2.37 (6); 2.2, 2.2, 2.1 ($). Described from one male and seven females, all taken by the writer at Skagway, Alaska, June 18-21, 1924. It is quite distinct from the preceding species by the above characters, and from all allied forms by the peculiar apical process of the last ventral in the female. *Hydroporus recticollis Fall, n. sp. Closely allied to the preceding two species, but more especially to alaskanus with which it agrees in the short parallel-sided thorax with rectangular hind angles, the nearly straight sides extremely finely margined. The form is more strongly elongate, the thorax smaller than in either of the preceding two species and not much wider than the head; elytra from five and one-half to six times the thoracic length. Black markings of the upper surface heavier than in the preceding species, the thoracic disc becoming diffusely clouded, leaving the margins and a narrow central line pale; the black elytral vittae much wider than the intervening yellow lines and the external fragmentary vittse more developed. There is a tendency here, as in all species of the group, for the first and second elytral vittae to become confluent in a small antemedian spot. The epipleura are entirely blackish. In the male, as in the preceding species, the pro- tarsi are perceptibly more dilated than in the female, the second joint a little wider than either the first or third; the claws mutually equal, slender and not differing sexually. The last ventral is longi- tudinally medially impressed in apical half in the male. In the female the last ventral is rather abruptly flattened or impressed around the apical margin, which is at middle a little deflexed, but not distinctly produced. The subapical marginal angulation of the elytra in the female is a little more prominent, being nearly rectangular in the present species, obviously obtuse in the two preceding. Length (male type), 5.2 mm.; width, 2.3 mm. In two females the dimensions are 4.9 and 2.15 and 4.8 by 2.15 mm. Described from one male and two female examples, taken by the writer at Seward (Kenai Peninsula), Alaska, July 18, 1924. JANUARY, 1926] FALL ALASKAN COLEOPTERA 141 The five species now known from our fauna, in this restricted group having the sides of the elytra of the female subapically angulate, may be tabulated as follows : Prothorax wider at base than at middle. Protarsal claws not differing appreciably in the sexes, femora entirely pale 12-lineatus Protarsal claws slightly thickened in the male; femora blackish in basal half to three-fourths. Sides of thorax arcuate throughout semiclarus Sides of thorax nearly straight yukonensis Prothorax not appreciably wider at base than at middle, the sides virtually straight and parallel in at least basal half; protarsal claws of male not at all thickened. Last ventral of female with a broad deflexed apical process alaskanus Last ventral of female without broad apical process; general form a little more elongate; prothorax smaller and with broad diffuse discal cloud recticollis Agabus hypomels Mann.

San Juan (Evans Island). Agabus nigroceneus Er. Fairbanks. *Agabus kenaiensis Fall, n. sp. Obtusely oblong oval, black, antennae and legs brownish, the thighs darker, especially the posterior. Body only moderately con- vex, surface rather strongly shining, minutely alutaceous and with a feebly impressed system of much larger reticulations which are quite irregular in form. Punctuation apparently lacking, except for the usual irregular finely setigerous elytral series and similar irregular series along the front margin and the exterior third of the rear margin of the prothorax. Closer inspection, however, reveals numer- ous scattered very minute punctures mostly at the intersections of the fine reticulating lines. Head with two faint rufous occipital spots. Prothorax a little less than three times as wide as long, sides feebly arcuate, nearly continuous with the sides of the elytra. Margin mod- erate, base just perceptibly sinuate each side of the middle. Elytra two-thirds as long as wide, slightly wider at middle than at base, sides subparallel in basal two-thirds. Body beneath alutaceous- reticulate, with a few fine punctures; ventral surface with some 142 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 widely spaced oblique very fine striae, especially on the second seg- ment. Prosternal process roof-shaped; hind coxal plates distant by rather less than half their own length from the middle coxal cavi- ties; hind tibiae with a few punctures along their inner margin. Male. Anterior tarsi feebly dilated, somewhat compressed, clothed beneath with rather long squamules bearing at their tips a few small inconspicuous palettes; prosternal claws a little elongate, slender, equal, the posterior with a more pronounced basal sinuation of the inner margin. Length, 6.25 mm.; width, 3.3 mm. Described from two completely similar male specimens taken by the writer at Anchorage, Alaska, July 14, 1924. They occurred in wet moss. This species is nearly allied to confertus, differing in its much smaller size, somewhat narrower form, elytra without a trace of a sublateral pale spot, last ventral segment of male nearly destitute of the longitudinal strigae so conspicuous in confertus. In the present species the posterior protarsal claw shows the more conspicuous basal sinuation, while in confertus it is the anterior claw. *Agabus gelidus Fall, n. sp. Moderately elongate, oblong oval, barely perceptibly inflated pos- teriorly, elytra and thorax nearly continuous in outline; black, mod- erately shining; antennas dark rufous; legs piceo-rufous. Very simi- lar in most of its characters to confertus, with which it agrees nearly in size and form; the sculpture above consists as in confertus, of a system of rather large irregular reticulations within which the sur- face is more finely reticulate, with sparse, very fine scattered punc- tures, which may lie either within the meshes or on the reticulating lines. As in confertus, the metastenial groove for the reception of the tip of the prosternal process is quite rudimentary. The series of punctures along the inner margin of the hind tibiae are very few in number, and the present species differs otherwise from confertus in the narrower side margins of the prothorax, and notably in the much narrower wings of the metasternum between the middle coxal cavities and the hind coxal plates, this distance being in the present species less than half the distance across the coxal plate, while in confertus it is obviously greater than half the width of the coxal plate. The sublateral yellow spot of the elytra is wanting in gelidus, and the longitudinal strigation of the last ventral in the male is only feebly developed, there being, however, a broad median impressed area extending from apex nearly to base of the segment, which seems to be wholly wanting in confertus. The protarsi of the male are similarly but noticeably more strongly dilated and compressed in gelidus, the protarsal claws elongate and sinuate on the inner margin in about the same degree.

Of large size (2 mm.) and rather narrow form, polished, impunc- tate, except for the minute punctures bearing the elytral hairs; brown, with the sutural edge nigrescent basally. Pubescence yellowish- brown, stiff and posteriorly directed on the occiput, similarly rather densely bristling at sides of prothorax; longer, finer, sparser and more reclinate on the elytra. Head much longer than wide, scarcely more than half as wide as the prothorax; sides of the occiput nearly straight and convergent for about four times the length of the small anterior eyes, to the strongly constricted neck, the latter about one- half the width of the head. Antennae fully half the length of the body, without definitely limited club; second joint subcylindrical, slightly wider apically, twice as long as wide and nearly equal to the two following; three to six equal in width to the second and mutually nearly similar, suboblong, slightly longer than wide; seven to ten gradually wider and becoming a little transverse; eleven not quite as long as the two preceding. Prothorax distinctly longer than wide, sides parallel and arcuate before the posterior lateral constric- tion, subbasal transverse impression feebly trifoveate at middle and at hind angles, the latter with short carina. Elytra elongate oval, widest at middle, about two-thirds longer than wide and two-thirds wider than the prothorax; basal impression strong, subhumeral and sutural impressions obsolete. Femora moderately clavate; tibiae wider medially, tarsi rather short and stout, basal joint subequal to the two following; apical a little longer than the basal; hind coxae sub- contiguous. Length, 1.95 mm.; width, .75 mm. Ketchikan, Alaska, August 1, 1924, a single example sifted from damp moss. Although possessing the essential characters of Euconnus, this species does not fit very well in any of the groups of the genus established by Casey. The very elongate head should make it easily recognizable among all known species of the genus. The sex of the single individual is uncertain, but the slightly broader basal joint of the protarsus may indicate the male. *Scydmaenus adjutor Fall, n. sp. Elongate, suboval, only moderately ventricose; black, antennae and legs brownish ferruginous; surface polished, head and prothorax impunctate, elytra with fine sparse punctulation; pubescence fine, sparse and reclinate or inclined. Head wider than long; eyes rather prominent, subbasal, the tempora very short and rapidly convergent; excavation of the vertex broad and shallow, vaguely biimpressed at bottom. Antennae gradually incrassate, the eighth joint slightly, the ninth and tenth more distinctly, transverse; joints proportionately nearly as in pacificus. Prothorax a little longer than wide, sides mod- erately rounded in apical half, constricted at basal third; surface coarsely biimpressed laterally within the constriction and with a JANUARY, 1926] FALL ALASKAN COLEOPTERA 145 short subbasal dorsal transverse impression. Elytra oval, widest near middle, three-fourths wider than thorax, one-half longer than wide; humeri obtusely rounded but evident; basal impressions nearly as in pacificus’, legs as in pacificus. Length (head depressed), 1.2 to 1.3 mm.; width, .55 mm. Described from two examples taken by the writer at Skag- way, Alaska, July 27, 1924. This species is a Brachycepsis, closely allied to suhpunctatus and pacificus. It is very considerably smaller than either of the two mentioned, and differs from pacificus also in its black color (rufotestaceous in pacificus), rather more slender antennas and slightly less ventricose elytra, which are widest more nearly at the middle. There is no apparent indication of sex in either of the two specimens. Eiifheia (Veraphis) scitula Makl. Scow Bay. FAMILY ORTHOPERID^ ^Orthoperus scutellaris Lee.

II, NO. 3 *Trogophloeus alaskanus Fall, n. sp. Moderately slender, depressed, sublinear; black, legs black, the tibiae internally, tarsi, mouth and base of palpi testaceous; antennae piceous. Upper surface densely, finely punctate and feebly shining; abdomen, especially toward apex, more sparsely punctate and shin- ing; pubescence very short and fine. Head quadrate, hind angles subrectangularly rounded; tempora slightly longer than the eyes, straight and parallel; vertex broadly roundly impressed Eyes small, just perceptibly more prominent than the tempora, attaining the middle of the elytra. Antennas moderately slender, gradually in- crassate, the outer three joints forming a feebly differentiated club; joints four to eight about as long as wide, fourth smallest, eighth just perceptibly transverse. Prothorax equal in width to the head, a little wider than long, front angles nearly right and scarcely rounded, sides broadly arcuate and feebly convergent from just be- hind the apex; hind angles obtuse and rounded as viewed from above; disc with an oblong impression occupying the apical two- thirds of the length and the middle one-third of the width. Elytra distinctly wider than thorax, subequal in length to the head and thorax combined and much longer than wide. Abdomen slightly narrower at base than the elytra and slightly widened behind, border rather thick but shallow; ventral segments four to six impressed at middle, the fourth very feebly, the sixth broadly and deeply, the apex of the latter behind the impression briefly carinate, the margin broadly angulate medially. Legs moderately slender. Length, 1.6 mm.; width, .45 mm. McKinley Park Station, Alaska, July 9, 1924; a single ex- ample taken by the writer. This little species belongs to Group IV of Casey’s Revision, and by the table would be associated with indigens, from which it differs in a number of details, notably the longer elytra, dark legs, and ventral impressions. *Trogophloeus teres Fall, n. sp. Closely related to the preceding species, but apparently distinct by the following differences: Size larger (2.3 mm.), elytra piceo- testaceous, legs entirely pale; prothorax slightly wider than the head and relatively more transverse, the impression much larger, extend- ing almost throughout the length, at the base involving almost the entire discal width, but becoming narrower and more vague anteri- orly. Elytra even slightly longer than in alaskanus, abdomen more distinctly narrowed basally and more strongly punctured, less shin- ing. Ventral segments not impressed. A single specimen only, taken at McKinley Park Station on the same date as the preceding, but whether the two specimens were taken together I do not recall. There is perhaps a possi- JANUARY, 1926] FALL ALASKAN COLEOPTERA 147 bility that they are sexes of one species, the difference in color being due to immaturity. This point can only be settled by further collecting. So far as I know these are the first species of the genus to be recorded from Alaska. Aploderus sp. Female. Ketchikan. This seems much like princeps, but without the male definite determination is difficult. Oxytelus invenustus Csy. ? One female. White Horse. A male example taken at Edmonton, Alberta, on this trip, and others in my collection from Banff, Alberta, and Beulah, New Mexico, appear to possess precisely the male sexual characters described by Casey from his Maryland type. ^'Oxytelus suspectus Csy.

I have also a specimen of this species taken by Wickham at Fort Wrangel; this is, I suppose, one of the two undetermined species mentioned by Wickham in his list. Stenus ptej'obrachys G. and H. Juneau; Sitka; Ketchikan. * Stenus stygicus Say. Eagle. ^Stenus mammops Csy. Anchorage. Stenus cariniceps Makl. Juneau; Ketchikan. Ten other as yet unidentified species of Stenus were taken in Alaska. I had hoped to be able before this to compare these with Casey’s types, but Mr. Barber writes me that the latter are not yet available for study. *Lathrobium sollicitum Fall, n. sp. Form nearly parallel; black, antennas piceous, base scarcely paler; legs rufopiceous, the tibiae paler. Head, thorax and elytra polished, abdomen dull from the density of the minute punctulation. Antennae rather slender, not quite reaching the thoracic base, intermediate joints all feebly obconic and a little longer than wide. Head behind the clypeus subquadrate, sides parallel, hind angles broadly rounded, base truncate at middle, punctures numerous but well separated, median line smoother; eyes at about twice their length from the 148 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 base; gular sutures parallel and widely separated; neck one-third the width of the head. Prothorax slightly wider than the head, about one-fourth longer than wide, sides parallel, feebly arcuate, front angles rather abruptly, hind angles more broadly, rounded; punctua- tion strong, not very close, median line narrowly but indefinitely smooth. Elytra equal in length and in maximum width to the thorax, sides very feebly but perceptibly divergent from base to apex, punctures similar to those of the thorax but rather sparser. Abdo- men at base equal in width to the elytra, very slightly widened to apical third, very finely, densely punctulate and dull, both above and beneath. Legs moderately stout, the front thighs thickened but not sinuate beneath. Length, 5.2 to 5.4 mm.; maximum width, .9 mm. Described from two males taken by the writer at Anchorage, Alaska, July 13-14, 1924. In these the sixth dorsal abdominal segment is strongly acumi- nate at apex, the sixth ventral with a very small apical emargi- nation, triangular in form with its apex narrowly rounded. By its narrow neck, this species should be referred to the group Tartopeus, but does not resemble at all any species therein defined by Casey, unless it be his lacustris, which is apparently quite different from the other species of his table, and is seemingly remindful of the more typical Lathrobii. In lacustris the elytra are said to be shorter than the thorax, and the sexual characters of the abdomen are not like those in sollicitum. Lathrobium finitimum Lee. Scow Bay. Lathrobium subseriatum Lee. Kasaan. ^Lathrobium sewardi Fall, n. sp. Form moderately slender and convex. Head, thorax, and basal half of elytra brownish piceous or castaneous, apical half of elytra brighter rufous; abdomen piceous, antennae and legs reddish-brown. Head subquadrate, sides straight and parallel, hind angles broadly rounded, base truncate; eyes small, at twice their length from the base; surface densely punctate at sides and base, less closely so medially. Antennae attaining base of prothorax, median joints ob- conical and about one-half longer than wide. Prothorax slightly narrower than the head, one-third longer than wide, widest at apex, sides nearly straight and convergent to base; all angles broadly rounded; punctuation close and confused, median impunctate line subelevated. Elytra as wide as the head, subequal in length to the prothorax, and one-sixth or one-seventh longer than wide; sides parallel, surface coarsely and closely sublinearly punctate. Abdomen very finely not closely punctate. Male. Ventral segments two to six with median impressions in- JANUARY, 1926] FALL ALASKAN COLEOPTERA 149 creasing in size and depth, margin of fifth segment broadly sinuate, apex of sixth with suboval or elliptical emargination, its limiting angles sharply subrectangular, the impression anteriorly with a dense patch of short black spicules, narrowly divided along the middle. Length, 5.8 to 7 mm.; width, .9 to 1 mm. Described from two males and four females taken by the writer at Seward, Alaska, July 18-20, 1924. This species belongs to Casey’s genus Lobrathium and is very closely related to tacoma; Csy., differing most notably in color and the less slender antennae; the secondary sexual characters are nearly identical. Baptolinus macrocephalus Nordm. Ketchikan ; Seward ; Kasaan ; Skagway. Philonthus septentrionis Fall, n. sp. Deep black throughout, polished, elytra with slightly green bronze luster. Head quadrate oval in male, a little more oval in the female; eyes distant their own length from the base of the head. Antennae barely as long as the head and thorax, entirely black; joints eight to ten as wide or slightly wider than long, the preceding joints slightly more elongate. Prothorax quadrate oval, one-third to two-fifths wider than the head, evidently narrowed in front; dorsal punctures fine, three in number, equidistant. Elytra a little wider than the thorax, nearly square or very slightly transverse; punctuation rather fine and sparse, not distinctly muricate. Abdomen sparsely a little more strongly punctate than the elytra, beneath still more coarsely so. Male. Anterior tarsi moderately strongly dilated; last ventral with a triangular emargination a little wider than deep, and surrounded by an acutely angulate gutter. Length, 6 to 7 mm.; width, 1.4 to 1.6 mm. Described from one male and two female examples collected by the writer at Dawson, Yukon Territory, June 24, 1924. This species is of about the size and aspect of umhratilis, and may be placed near it. In the latter the tempora are shorter, the thorax less narrowed in front and with coarser serial punc- tures, the abdomen more finely punctured beneath, and the legs brownish-red. Philonthus hasalis Horn, var. Dawson. Three examples differ- ing from the typical form by having the elytra varied with fuscous. Philonthus fraternus Fall, n. sp. Moderately elongate, deep black, shining, tarsi alone brownish. 150 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 Antennae not quite as long as the head and thorax, outer joints nearly square. Head subquadrate, three-fifths as wide as the thorax, the latter as long as wide, distinctly narrowed in front; dorsal punc- tures four, equidistant. Elytra nearly square, a little wider than the thorax, not at all aeneous, punctuation rather sparse. Abdomen a little more finely and equally sparsely punctate. Male. Front tarsi very broadly dilated, last ventral triangularly emarginate and with a rather deep longitudinal impression tapering forward and extending the entire length of the segment; penulti- mate segment very broadly angulato-sinuate. Length, 6 mm.; width, 1.4 mm. Dawson, Yukon Territory, June 24, 1924, a single male specimen taken by the writer. This species can only be compared with quadricollis and the- veneti, because of the last ventral of the male being longitudi- nally impressed throughout its length. In both these latter spe- cies the sides of the thorax are parallel or very nearly so, while in the present one they are distinctly convergent. Qiiadricollis has the legs and antennae brown or paler and theveneti is said to have the elytra not wider than the thorax. ^Philonthus sp. Ketchikan.

FAMILY LAMPYRID^ *Podabrus comes conspiratus Fall. n. var. This name is proposed for a form of which a single example was taken at Skagway. It may or may not be a form of the Californian comes, the amount of variability of which within specific limits is not definitely known. The present specimen differs from all my comes (so labelled) by the slightly more transverse thorax, which is a little less rounded on the sides and without visible sinuation at the hind angles, which are not perceptibly prominent. The thorax also lacks the median eroded line and has the front margin blackish at middle. It agrees otherwise in color with the typical comes except that the pos- terior ventral segments are not margined with yellow, the ter- minal segment being merely feebly paler at tip. Length, 14 mm. Skagway, Alaska, June 18-20, 1924; a single female. *Podabrus tetragonoderus Fall. n. sp. Moderately elongate, black, clypeus at sides, sides of pro- thorax and basal three joints of antennae beneath, yellow; elytra with a grayish aspect due to the rather plentiful ashy pubes- cence. Antennae longer than half the body; second joint a little narrower but subequal in length to the third ( 6 ), or a little shorter than the third ( 2 ) ; third joint subtriangular, a little longer than wide, distinctly wider than the fourth in the male, less noticeably so in the female; following joints nearly parallel-sided, becoming gradually more slender, the fourth a little more than twice, the outer joints fully three times, as long as wide. Head ( 6 ) just perceptibly narrower than the thorax; eyes moderate; the eyes less prominent and the head narrower in the female; clypeus and front as far back as a line joining the posterior part of the eyes nearly smooth ; occiput closely, rugosely punctate but shining. Prothorax quadrate, a little wider than long, not or barely perceptibly wider near the front angles ; sides nearly parallel and straight ; a very faint sinuation before JANUARY, 1926] FALL ALASKAN COLEOPTERA 153 the sharply defined hind angles, front angles rounded, posterior discal elevations rather strong and situated within the broad dorsal black stripe, which is dilated behind the middle; sur- face distinctly but not deeply punctate throughout, more finely so in the yellow margins and between the discal elevations ; median line finely eroded in posterior two-thirds. Elytra finely scabrous punctate. Legs black, front tibiae in the single female a little dilute in color. Claws ( 6 ) finely cleft, the inner por- tion approximate to, and nearly as long as, the outer on the front and middle feet, much shorter but still finely acute on the hind feet. In the female the inner portion of the claw is much shorter than the outer on all feet, and the claws might perhaps better be described as having a basal dilatation with the free angle sharply acuminate. Length, 7 to 9.5 mm. Described from three males and one female, taken by the writer at Skagway, Alaska, June 18-20, 1924. This species will not enter any of LeConte’s groups as defined though coming nearest to Group C. There are other species in my collection with ungual characters similar to the present one and I hope shortly to publish already prepared descriptions of these and other new species of the genus. *Podabrus fissilis Fall, n. sp. Black, feebly shining; muzzle and two or three basal joints of antennae beneath rufotestaceous. Antennae slender; second joint but little more than half the third in the male, a little shorter than the third in the female. Head conspicuously wider than the thorax ( 6 ), or subequal in width to it ( 9 ) ; sur- face alutaceous and opaque, front sparsely punctate. Prothorax small, nearly as long as wide in the male, front angles obliquely subtruncate, sides a little convergent thence to the somewhat prominent hind angles. There is a small rufescent marginal spot just behind the front angles in the male which is entirely lacking in the female. Prothorax finely punctate and alutaceous, sculpture as usual. Elytra very finely scabrous ; tarsal claws all finely cleft in the male, the inner part shorter on the pos- terior four feet ; all claws toothed at base in the female. Length, 6 to 7 mm. Described from a single pair (type male) collected at Emerald Lake, British Columbia, by Dr. A. Fenyes. This is 154 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 the first nearly entirely black species to be described having tarsal claws all finely cleft in the male. Since writing the above description I have taken a single male of this species at Skagway, Alaska. Podabrus piniphilus Esch. Skagway; Seward.

NOTES ON PARASITES AT SATICOY, CALIFORNIA, DURING THE YEAR 1925 BY STANLEY E. FLANDERS Satie oy, California On February 28 a braconid of the genus M onogonogastra was reared from a walnut twig which contained the dead larvae of Polycaon confertus Lee. During April numbers of these dusky-winged, red-bodied braconids were observed about the walnut leaves. One individual was seen December 4. Through June and July a number of the metallic-blue ichneu- 158 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 3 mon-flies Amhlyteles cceruleus (Cr.), and the yellow and black A. zehratus (Cr.) were reared from the pupse of Sahulodes forficaria Guen. Hovering- about the blossoms of a large eucalyptus tree on April 2 were many of the syrphid parasites, Homotropus deco- rat us (Cr.). During October a black chalcid, Zatropis tortricidis Craw- ford, was reared from the linia-bean pod-borer, Etiella zincke- nella Treit. It pupates free in the pod, and is in the pupal stage seventeen days. On June 11 the gray, oval larvae of a species of Euplectrus were observed in a cluster on the dorsum of a caterpillar of Sahulodes forficaria. Later, several of these parasitized cater- pillars were found. From the pupae of the lichen caterpillar, Illice nexa Boisd,, a number of specimens of the tachinid, Pseudochceta argenti- frons Coq., were reared in May. On June 20 three females of Epiurus sp. (possibly Pimpla albipes Cr. described from Mexico) were reared from Ar chips argyrospila Walk. Their silken cocoons were spun on walnut about the remains of the caterpillar. Six small chalcids of the genus Elachertus were reared in June from a caterpillar of Ar chips argyrospila. On April 29 a walnut aphis, Chromaphis juglandicola Kalt., was found parasitized by Aphelinus perpallidus Gahan. It is only occasionally that such a parasitized aphis is found. While collecting codling moth larvae from burlap bands on walnut trees during March, a light brovm ichneumon-fly, Exe- tastes n. sp., was taken from a codling moth cocoon. Between May 1 and July 21 twenty-four tachinids of the genus Lixophaga were reared from three hundred overwinter- ing codling moth larvae. The maggot pupates within twelve hours after leaving the caterpillar. The length of the pupal stage was nineteen and twenty days. The identification of the parasites noted were kindly made by the specialists, R. A. Cushman, A. B. Gahan, S. A. Rohwer, J. M. Aldrich, and P. H. Timberlake. JANUARY, 1926] KESSEL LASIOPHTICUS PYRASTRI 159 SEX-LIMITED POLYCHROMATISM IN LASIOPHTICUS PYRASTRI (LINN.) BY E. L. KESSEL Early last June I collected a large population of the common syrphid fly Lasiophticus pyrastri (Linn.) on the University Farm at Davis, California. This series, which was taken by sweeping so as to be representative of the fauna, numbered 277 individuals. When a classification was made, there were found to be 235 specimens of the normal bicolored phase, of which number 98 were females and 137 were males. This is a de- cidedly unbalanced sex ratio. The remaining 42 members of the population were of the melanic variety, described by Curtis as unicolor. It was observed that all of these melanic flies were females, and it is interesting to note that when their number is added to the 98 females of the bicolored type there appears the well-balanced sex ratio for the whole population of 140 females and 137 males. The above data lead to the conclusion that the melanic form unicolor appears only in the female sex. Moreover, Curtis, in his description of this variety, gives the impression that he had but one specimen, and his colored illustration is definitely that of a female. Still more evidence was obtained from an examination of the material in the collection of the California Academy of Sciences. This series contains thirteen specimens of unicolor collected in various parts of California, and all of these are females. The evidence, therefore, appears to be conclusive. An intermediate form, although comparatively rare, also occurs. I took three specimens of this variety in Davis last June, but these were obtained by selective collecting. They are characterized by having the yellow markings persisting on the second abdominal segment, although they are much reduced in size. The California Academy of Sciences has one such indi- vidual collected by Dr. E. C. Van Dyke on Mount Ranier, Washington, in 1920. Two other specimens are cited by Cole and Lovett in their “Diptera of Oregon.” All six of these in- termediates are also females. We may, therefore, assume that this variety, as well as the completely melanic one, is sex- limited to the female. The species, therefore, appears to be an example of sex-limited polychromatism, in which there is only one type of male but three types of females. THE PAN-PACIFIC ENTOMOLOGIST Published quarterly by the Pacific Coast Entomological Society in co-operation with the California Academy of Sciences E. P. Van Duzee, Editor F. E. Blaisdell, M. D., Treasurer Through an oversight the legend was omitted from the plate of Hypolimnas holina L. in the October number of this journal. A gummed slip to be attached to this plate is enclosed. On March 23 the Pacific Coast Entomological Society gave a complimentary dinner to Dr. and Mrs. William Barnes of Decatur, Illinois, and Dr. and Mrs. R. J. Tillyard of Nelson, New Zealand. Dr. Barnes gave the society an interesting account of his work on the North American Lepidoptera and Dr. Tillyard on his work at the Cawthorn Institute of Scien- tific Research at Nelson. Dr. Barnes spent several days at the Academy of Sciences, and his suggestions added much of value to the Academy collection of Lepidoptera. The recent death of Mr. Richard H. Stretch at his Seattle home has removed one of the few remaining landmarks of early western entomology. About fifty years ago he amassed a very complete collection of the Bombycine moths of the world. This he presented to the University of California. So much of this collection as has escaped the ravages of pests has recently come into the care of the California Academy of Sciences as a per- manent loan, where it will be accessible to those interested in the published work of Mr. Stretch. Mr. E. Piazza, well known to our Lepidopterists as a suc- cessful collector of moths, died in New York, March 9, 1926. while on his way to England to visit his sister. Although an invalid for years he has been able to do much valuable work in the collection of moths for Scientific Institutions. Through the generosity of friends we are able to give our subscribers sixteen extra pages in this number of the Pan- Pacific Entomologist. This enables us to include two larger papers that otherwise it would have been impossible to publish in full. The April number should follow this with little delay. The October number was mailed January 16, 1926. Dr. F. E. Blaisdell writes us that it will be impossible for him to determine Coleoptera for his correspondents after Sep- tember 1, 1926, and asks that we call the attention of coleop- terists to this notice.

(CHAOBORIDT:; DIPTERA) BY STANLEY B. FREEBORN University of California, Berkeley, California For several years complaints have been received at the University from the vicinity of Clear Lake, Lake County, California, concerning the pest of gnats which inundates the country near the lake throughout the summer months. These insects are non-biting but are so numerous that they make life almost unbearable by flying into the eyes and mouth, con- taminating food and filling store windows inches deep with their dead bodies if white lights are exposed in the evening. Nearly all the householders and campers in the vicinity of the lake have been forced to use red shaded lights for illumination to prevent being swamped with these insects. An examination in 1925 proved them to be chaoborids of the subgenus Sayomyia and they were provisionally determined as Chaohorus (Sayomyia) astictopus Dyar and Shannon. A care- ful study of new material proves them to be a distinct species, the description of which follows : Chaoborus (Sayomyia) lacustris Freeborn, sp. nov. Male. Head: Pale brown with vestitiire of straw-colored hairs. Tori large, occupying nearly whole width of face, pale brown, api- cally excavated and bearing plumose antennae; antennae translucent except at whorls, hairs of which are golden yellow. Clypeus flat- tened, prominent, densely covered with golden hairs, pale brown and darker at margins. Proboscis and palpi transparent with brown markings. Eyes dark red. Thorax: Prothoracic lobes large but not contiguous, anterior half rich brown, posterior white. Posterior pronotum white with brown stripe along dorsal margin and slight infuscation on posterior margin. Mesonotum white shading to cream with rich brown markings bor- dered by lines of darker brown arranged as follows: two median stripes tapering posteriorly starting at anterior border and ending at antescutellar space, two subdorsal stripes tapering posteriorb^ start- 162 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 ing on either side of median stripes at point midway of disc and ending at scutellum; faint triangular spot with base at scutellum and apex pointing between two median stripes; pale circular spot indefi- nitely defined between anterior end of each subdorsal stripe and anterior margin. Scutellum white at center with brown markings at each side, vestiture of golden hairs. Postscutellum dark brown with a median, V-shaped, white cleft at the anterior margin. Pleurae pale cream with numerous brown markings, most conspicuous of which is that covering lower three-fourths of the sternopleurite. Prothoracic sclerites densely haired, others smooth, bare except four upper mese- pimerals. Halteres entirely white. Legs densely hairy, creamy white with brown markings; forelegs more heavily pigmented than others; femora with subapical brown bands and brown spots at hair inser- tions, tibiae with subbasal and subapical brown bands and brown spots at hair insertions, basitarsus as long as next two segments, each segment with apical brown ring growing fainter on the distal segments. Claws simple. Wing veins clothed with narrow, hair-like scales, anterior margin clothed with narrow, appressed scales, pos- terior margin with two lengths of lanceolate scales, one short and other longer than greatest distance between anal vein and hind margin. Slight brownish stains on wing membrane at base of R2, at fork of R2-1-3, at r-m and m-cu. Marginal distance between termi- nations of R1 and Sc almost twice that between R1 and R2, Fork of R2 and R3 distinctly distad of fork of MH-2 and M3+4. R2 slightly down-curved at margin. Crossveins r-m and m-cu forming continuous line. Cu2 becomes evanescent at margin, but appears to incline forward and run parallel with the margin. Tillyard’s “Cu2” is fully as prominent as the so-called Cu2 paralleling Cu2 to point near margin, anal vein prominent, down-curved near margin and paralleled by prominent fold, another anal parallels hind margin. Abdomen: First segment translucent white, wider than long; second to seventh longer than wide, translucent white, lateral mar- gins of tergite and sternite dark brown, the coloring becoming progressively narrower as the mid-dorsum and mid-sternum is approached, giving appearance of lateral triangles; seventh largely brown; eighth funnel-shaped, one-fourth length of seventh and rotated 180 degrees. Terminalia: Gonostyles (side pieces) slender at base expanding to tip, stained with brown on outer half; a subapical, rounded lobe bears three and sometimes four stout spines, the inner face from base to lobe heavily studded with bent hairs not markedly different in size from spines of lobe; dististyles (claspers) bent, pale at base, brown at tip, which is very slightly expanded, no appendage (claw). Paraprocts (tenth sternites) curving around base of gonostyles with onl}'^ terminal points parallel to the latter, pale at base, deeply pig- mented at tip which is cleft in two parts so that they resemble inverted high-heeled cow-puncher’s boots. In balsam mounts two APRIL, 1926] FREEBORN CHAOBORUS 163 paraprocts are straightened and take V-shaped position with ter- minal ends pointing laterally and caudally. Length of male 5 mm. Female. Similar in coloration to male except that pigmentation is more pronounced and deeper brown; triangle in antescutellar space not always distinct; first abdominal tergite with dark pigmentation, dark markings of venter limited to scattered spots; tarsal rings more distinct than in male^ last segment all brown; stained areas on wings more pronounced and numerous, all forks and most marginal termi- nations of veins with stained area. Palpi with basal segments swollen, the terminal one as long as combined length of two segments pre- ceding, slender, annulated. Abdominal segments wider than long. Claws simple. Length, 4 mm. Type, male, California Academy of Sciences, No. 1873, Lake- port, Lake County, California, July 19, 1925. This species falls near C. punctipennis Say and C. astictopus D. and S. It differs from both in having very pronounced markings on the mesonotum and in the form of the paraprocts. The abdominal markings in the female agree closely with those of astictopus and the chaetotaxy of the gonostyle is very similar to that of punctipennis. LABOPS BURMEISTERI STAL In the March, 1926, number of the Canadian Entomologist Dr. Knight requests information regarding the occurrence of Lahops burmeisteri in New York State. With the consent of Mr. Evans I retained the specimen of this species which I determined in 1909 and a reexamination of this specimen shows it to be the true burmeisteri as determined by Dr. Knight. At the time I made this determination I had a second specimen from the Adirondack Mountains of New York, which passed through my hands for study, so the New York determination can be depended upon. I have not time now to look up the Alaskan record and it is possible that may refer to the form later described as tumidifrons Kngt. In my material of hirtus Kngt. one specimen from New Mexico has the tibiae altogether black with the long tibial hairs and male claspers of hirtus, so the color of the tibiae cannot be relied upon in separating these forms. Labops hesperius Uhl. as restricted by Knight is still unknown to me. — E. P. Van Duzee. 164 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 A NEW SPECIES OF SCENOPINID.E FROM CALIFORNIA (DIPTERA) BY M.

MACDOUGALL University of Toronto The following species of Macrosiphum are described from collections made in British Columbia during the summers of 1923-25 inclusive. All measurements are in millimeters and whenever possible are an average of a number of specimens. Length of body is measured from the vertex to the tip of cauda. The width given is that of the widest part of the abdomen. Owing to the large area covered and the great distance between various collecting points, it was impossible to take a complete series in every case. However, these descriptions will, it is hoped, serve as a basis for further study of some interesting species from a comparatively new territory and aid in their identification by workers in these districts. 1. Macrosiphum audeni Macdougall, n. sp. Fig. I This species occurs in dense colonies on the upper sides of the leaves of N ymphaea polysepalum, clustering toward the petiole. The specimens from which the descriptions were made were collected by Mr. K. F. Auden in the summer of 1924 at Merritt, British Columbia, after whom the species is named. It was taken also by Mr. G. Spencer near Victoria, British Columbia, in 1925, and by the author the same summer at Lakelse Lake in the northern part of the province. It is thought to be comparatively rare as many plants have been worked over in these and other localities which were all quite uninfested. Its distribution, however, as indicated by the above localities in which it was taken, is fairly general for the province. Apterous viviparous female General appearance: Color pale green^ head and upper portion of abdomen slightly darker; antennas light except segment VI and apex of V, which are dusky; coxae and femora pale; tarsi and tip of tibia dusky; cauda pale; cornicles pale, except tips which are dusky; eyes dark red; body long and fairly slender; cornicles not reaching to tips of cauda, reticulated at tip where dusk}% distinctly wider at base; 166 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 cauda long, irregularly ensiform; 2-4 sensoria on ant. seg. III. Beak fairly short, not reaching below second pair of coxae. Antennae much longer than body. Measurements: Body — length 3.5, width 1.4; ant. segs. — III .8, IV .7, V .5, VI .19+1.2; corn. — .9; cauda — .4; hind tarsi — .19. Alaie viviparous female General appearance: Color as above: antennae dusky except first two segments and extreme base of third; eyes dark red; legs pale except distal tips of tibia and femora and all of tarsi, which are dusky; basal half of cornicles pale, rest dusky; cauda clear. Body long and fairly slender, except when distended with embryos; where dusky cornicles are distinctly reticulated, long^ slender; cauda ensi- form, fairly hairy; basal two-thirds of ant. seg. Ill with row of 12-18 sensoria. Antennse slightly longer than body. Measurements: Body — length 3.5, width 1.6; ant. segs. — III .75, IV .72, V .65, VI .2-1.2; corn. — .8; caud — .3; hind tarsi — .17; fore wing — length 4.2, width 1.45; hind wing — length 2.02, width .69. All collections were made as recounted above on the follow- ing dates : Merritt, July 25 ; Victoria, British Columbia, August 8; Lakelse Lake, July 28. Type slides are deposited in the National Collection, Ottawa. Paratypes in the United States National Collection, Wash- ington, and in the author’s collectian. This species is closely related to Macrosiphum aquilegia Theo. 2. Macrosiphum bisensoriatum Macdougall, n. sp. Fig. II Found in abundance on the under side of leaves of Ribes lacustre during the summer months. No alternate host is known ; migrants appear at frequent intervals during the sum- mer. This species can readily be distinguished from Myzus ribis Linn, by the larger size and the fact that when disturbed they are inclined to fall from the leaf. Apterous viviparous female General appearance: Color dark green, head slightly lighter than the rest of the body; antennse pale except I and II, which are con- colorous with body, distal quarter of V, and all of VI, which are dusky; flange of cornicle dusky ^ rest clear; cauda abruptly ensiform, clear; beak reaching almost to third pair of coxse; last segment of APRIL, 1926] MACDOUGALL MACROSIPHUM 167 leg shading to brown; tips of tibia and all of tarsi dark brown, rest pale; head, cauda, ant. seg. Ill, and tibia prominently hairy. Two small sensoria on proximal half of ant. seg. III. Tip of cornicle dis- tinctly reticulated, rest imbricated. Body slender, graceful; antennae much longer than bodjG cornicles reaching to tip of cauda. * Measurements: Body — length 3.38, width 1.7; ant. segs. — III 9.5, IV .8, V .65, VI 16+1.15; cornicles — 1.1; cauda — .42; hind tarsi — 1.5. Alate viviparous female General appearance: Thorax very dark, rest as above; insect notice- ably smaller than above. Coloring of antennal segments as follows: I and II, concolorous with body, rest of antennae dusky; on dusky portion of seg. Ill is a row of 9 sensoria; near tip of V, one large one is found, and the usual number occur at base of spur of VI. Eyes red; beak quite long, clear, except last segment which is uni- formly dusky; coxae and basal two-thirds of femora pale, shading to the light brown of the rest of the femora; tibia light brown except tip, which is dark; tarsi dark brown; cornicles pale at base, shading to dusky flange, slightly constricted near tip; this part imbricated; cauda clear; wing veins distinct, dark brown; stigma rather pale. Antennae much longer than body. Measurements: Body — length 2.8, width 1.3; antennal segments — III .86, IV .7, V .6, VI .17-.9; cornicles— .8; cauda— .32; hind tarsi — 1.5; fore wing — length 3.7, width 1.3; hind wing — length 2, width .6. This species differs from Macrosiphum lactucce Pass in hav- ing fewer sensoria in both forms and minor differences in color and size. It was collected at Boundary Bay, British Columbia, at intervals, through July and August, 1924. Type slides are in the National Museum, Ottawa. Paratypes in the National Museum, Washington, and in the author’s collection. 3. Macrosiphum fuscicornis Macdougall, n. sp. Fig. Ill Found in colonies with Aphis oenother(B CEst. on stems and leaf buds of Bpilohium angustifolium, the dark green color of this form contrasting with the purple of the smaller one. It has been taken in different parts of the province during the summer. Alatse are comparatively rare, only having been found in June and the latter part of August. 168 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 Apterous viviparous female General appearance: Dark olive-green body; anteiinze brown throughout, darkening somewhat in VI, much longer than body; eyes red; legs uniformly dark except base of femora, which is pale; cornicles brown except at base, reaching beyond the tip of cauda, broader at base and slightly constricted near tip; cauda long, irregu- larly ensiform, light brown. Measurements: Body — length 3.18, width 1.6; ant. segs. — III 1.03, IV .94, V .83j VI .2-|-1.12; cornicles 1.4; cauda .5; hind tarsi .18. Alate viviparous female General appearance: Color approximately as above; thorax slightly darker than other parts of the body; aiitennse and cornicles strik- ingly long; eyes dark red; first two antennal segments dusky, III dusky except extreme base which is pale, IV getting paler, V and VI quite light. A more or less regular rov/ of sensoria along edge of III. Coxae and basal half of femora pale, rest of legs dusky; cor- nicles dusky, slightly paler immediately below flange; cauda pale; wing veins normal, stigma pale brown. Measurements: Body — length 2.6, width .89; ant. segs. — III .81, IV .8, V .72, VI 15-.8; cornicles — .9; cauda — .32; hind tarsi — 1.7; fore wing — length 3.7, width 1.38. This species has been collected at Jerico Beach near Van- couver, British Columbia, on August 24, 1924, and Merritt, British Columbia, June 29, 1924. It was observed in other parts of the province during the same summer. It is most closely related to Macrosiphum fragariellum Theo., but the cornicles are tapering and there is no indication of a swelling. Type slides in Canadian National Collection, Ottawa. Para- type slides in United States National Museum, Washington, and in the author’s collection. 4. Macrosiphum nigromaculosum Macdougall, n. sp. Fig. IV This very colorful Aphis is found, so far as the writer knows, only in the semi-arid valleys of the lower Cascades. It is clustered in masses along the stems of Rosa nutkana, seldom spreading, to the buds or leaves. Although collected from June to August, no adult or larval migrants were taken. Apterous viviparous female General appearance: Body bright red, fading to pink; cervicum APRIL, 1926] MACDOUGALL MACROSIPHUM 169 black, abdomen marked with three more or less regular black bands; appendages black, body broadly ovate with cornicles projecting out- ward at right angles giving the insect a most peculiar appearance. Specimens in balsam appear as follows: head and abdomen dark with lighter thorax^ antennal segments pale except ends of V and VI, which are dusky. Eyes very dark red; base of femora pale, rest of leg light brown, except tips of tibia and femora and all seven tarsi, which are dark; cornicles uniformly black, very broad at base, taper- ing gradually to the usual-sized flanged tip, reticulated throughout; cauda irregularly ensiform, shading from pale at base to dusky at tip; beak light brown except tip which is very dark, reaching to second pair of coxae; antennae, tibia and cauda prominently hairy. No sensoria on antennal segment III, but a very large one near tip of V and the usual group at the base of spur of VI, scarcely as long as the body. In cleared specimens the black pigment spots seem to be scattered rather unevenly in those parts of the body which appear banded. Measurements: Body — length 3.7, width 1.9; ant. segs. — III .9, IV .51, V .51, VI .15-. 74; cornicles — .7; cauda — .38; hind tarsi — .2. Collections of this species were made in Bootahnie Valley, June 28, 1924, and in Merritt on July 10 of the same year. During these months and August, no alatse were observed in either locality. Readily distinguished from other species occur- ring on Rosa by color, shape and habits. Type slides deposited in the Canadian National Collection, Ottawa. Paratypes in United States National Museum, Wash- ington, and in author’s collection, 5, Macrosiphum pyrifolias Macdougall, n. sp. Fig. V This species is fairly common in the vicinity of Merritt, British Columbia, on the leaves of Pyrus occidentalis during the summer. Although the sexes have not been found it is thought to spend the complete season on this host. Migrants occur regularly, a few of them being always present in a colony. Apterous viviparous female General appearance: Dusky brown in color^ head slightly darker than the rest of the body; antennal segments V, VI and tips of III, IV, dark brown, I and II concolorous with body; rest clear; eyes red; legs pale except tarsi and tips of tibise, which are dusky; corni- cles long, reaching just below tip of cauda, and pale, except distal third, which is dusky; cauda clear; body long, of average width; 170 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 embryos show distinctly; dusky portion of cornicles distinctly reticu- lated. Row of 14-17 sensoria on basal three-quarters of antennal seg- ment III. Cauda typically ensiform. Beak reaching to third pair of coxae; last segment dusky. Measurements: Body — length 3.4, width 1.4; ant. segs. — III .9, IV .75, V .7, VI .2-. 9; cornicles 1.1; cauda — 14; hind tarsi — 1.6. Alate viviparous female General appearance: Much darker than the apterous form; body narrower and antennae longer; body dark green-brown; cauda, basal half of femora, proximal part of antennal joint III, all pale; corni- cles dusky, uniformly colored; wider than in apterae; only the tip distinctly reticulated, barely reaching to tip of cauda; legs and an- tennae covered with fairly long, capitate hairs. Antennal joint III with 18-24 irregularly placed sensoria, more or less clustered in center. Measurements: Body — length 3.1, width 1.01; ant. segs. — III 1.1, IV 8.5, V 7.4, VI .19-1.2; cornicles — 1.1; cauda — .43; hind tarsi — .19; fore wing — length 4.55, width 1.6; hind wing — length 2.8, width .86. Collected May 27, 1924, in Merritt, British Columbia, by Mr. K. F. Auden, and in Tulameen on June 15 of the same year by the author. It was observed at other times in this locality. Nearest to Macrosiphum ulmarice Schrank, although it re- sembles this species only remotely. Type slides in Canadian National Collection, Ottawa. Para- types in the United States National Museum, Washington. 6. Macrosiphum subviride Macdougall, n. sp. Fig. VI This species is found on the stems and leaves of Aster alpinus which grows on the eastern slopes of the Cascade Mountains and in the Rockies. As it does not colonize, it is very difficult to detect on the pubescent surface of the host. Alatae are found continuously throughout the summer months. Early in August, however, the insects entirely disappear; the winter host is un- known. Transfer experiments were made with Aster occi- dentalis, but were found to be completely unsuccessful. Apterous viviparous female General appearance: Color delicate green, approximating that of the hairs of the host; antennal segments I and II pale.

II, NO. 4 NOTES ON THE GENUS STENOPELMATUS WITH DESCRIPTION OF A NEW SPECIES (ORTHOPTERA) BY ALONZO C. DAVIS AND LESLIE M. SMITPI In the course of some anatomical work which the writers were doing' with two undoubtedly distinct species of Stenopel- matus, it became necessary to know what species were being dealt with. One of the species was of large size, with the head, thorax, and legs usually light testaceous or somewhat fuscus. This species was dominant along the Berkeley hills and rarely extended its range into the low lying coastal shelf upon which the cities of Oakland and Berkeley are situated. In the hills this species was found only on grassy slopes, overhung by an out- cropping of rock which had strewn the slope with weathered fragments. Under these rocks this species constructs its burrows. The second species was much smaller, with the head, thorax and legs usually rufo-testaceous. This species was dominant on the low, flat belt bordering the San Francisco Bay in the neigh- borhood of Oakland. It was seldom taken in the hills, where the large species was fairly abundant. Throughout the residence section of the city this small species is fairly common. It burrows in the loose soil in backyard gardens and constructs tunnels beneath boxes, boards, etc., which are closely pressed to the ground. When living in the hills, it occurs in the same type of habitat as does the larger species. It was difficult to induce the large species to mate in the laboratory, but when this was done, it was found that the female pursues the male for several minutes prior to mating. The eggs of this species measure 3.7 — 3.8 x 2.0 — 2.2 mm. These insects can stridulate loudly enough to be heard at a distance of six feet. Stridulation is accomplished by rubbing the inner face of the hind femora against the opposing side of the abdomen. The smaller species mated readily in the laboratory ; in this case the male rapidly pursued the female while the latter in- variably retreated. The eggs of this species measure 2.9 — 3.1 x 1.8 — 1.95 mm. Stridulating organs are present and the femora are rubbed against the abdomien as in the large species. APRIL, 1926] DAVIS AND SMITH STENOPELMATUS 175 but the human ear can but rarely detect the sound, even at close range. A rather thorough search of the literature on the genus failed to net anything which would serve to identify these species. Hebard's table (N. Y. Ent. Soc., vol. XXIV, pp. 70-86)' is by far the best, but was inadequate in definitely determining indi- vidual specimens. The spines and spurs of the hind tibiae, upon which previous taxonomic work was largely based, are so variable in size and number as to be almost worthless. Speci- mens of the large and small species were sent to Mr, Caudell, who says : “I should say that from the variability of the char- acters used they all might be either longispina or fiiscns. The simplest way out would seem to be to call all specimens of this genus Stenopelmatus fuscus as all our crickets are now Gryllus assimilis/’ In the collection of the California Academy of Sciences there are specimens of Y. fuscus, longispina and pictus, about four- teen specimens in all, which were identified by Hebard, appar- ently on the basis of tibial spines, the relative length of metatarsus and inner apical spine of the hind tibia. This latter character, as has been pointed out, is not dependable and varies from one extreme (S. fuscus) to the other (S. longispina) in the same locality in Berkeley. From the above it would seem that there is as yet no definite character by which these two species may be separated. It is our opinion, based upon exami- nation of such material as is available, field study, and a study of breeding habits, that vS. fuscus and S. longispina are not distinct species, and that the latter name should be made a synonym of vS'. fuscus. After studying the literature, we have arrived at the conclusion that S. fuscus is the larger of the two species at hand and that the smaller species is as yet un- described, probably having been overlooked in the past as a nymph. The genus having comparatively recently lost its wings, the thorax is in an inconstant or transitional state, and relative dimensions are not to be relied upon to any great extent. The form and shape of the head is also inconstant, since the genus is subject to magacephaly and other abnormalities. The mouth- 176 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 parts, in the series examined, show no characters of value. The rugosity and dentition of the mandibles is fairly constant, except as use reduces the teeth. The ovipositor is of some value, when used comparatively. The male genitalia consist of a fleshy bursa copulatrix which seemingly presents no characters of value, and in any case is too difiicult to preserve to be of value in identifying cabinet material. The punctuation of the head shows differences of some value. Color is apparently not very reliable, varying from very light to dark in the same locality. In preserved specimens, unless in alcohol, it has been difficult to use measurements of the abdomen because of the great shriveling of the parts in drying. By injection and hard- ening these soft parts may be preserved in more or less their natural condition, but the size and shape of the abdomen varies much with the condition of the insect, whether or not full of food, eggs, parasites, etc. In general, the females are large and full-bodied. The males are usually somewhat smaller, with the legs longer and the abdomen smaller in proportion and laterally compressed. The characters which we have found to be of most value in distinguishing between S. fuscus Hald. and S. intermedius n. sp. are the shape of the anterior plate of the prosternum, the size and shape of the stridulating plates on the inner surface of the hind femora, punctuation of the head, basal antennal joints, and size. A number of attempts were made to interbreed 5. fuscus with S. intermedius. S. intermedius males were placed with S. fuscus females and S. fuscus males with S. intermedius females, but in no case did mating occur. No difficulty was experienced in breeding each species within itself. Stenopelmatus fuscus Hald. Punctures distinct along the frontal (epicranial) suture^ especially above and below the oblique arms between the eyes. On either side with two vertical lines of punctures, one just behind the eye and inclining slightly medially above, the other about halfway between the eye and the suture; these thin out above, but attain the vertex and in most cases extend to the anterior margin of the pronotum; angle at which the two oblique arms meet the frontal suture fairly obtuse; oblique arms nearly straight, their apparent ending being near the upper margin of the insertion of the basal antennal joint. Oblique sutures themselves wide and depressed. At and above the APRIL, 1926] DAVIS AND SMITH STENOPELMATUS 177 fronto-clypeal suture, with a triangular depressed rugose area, the sculpture tending to run in oblique lines from the center outward and downward. Punctuation in some immature specimens sparse, rarely failing to attain the vertex; lines of punctuation behind the eyes sometimes nearly lacking. Blades of the ovipositor, in compari- son with S. intermedins, somewhat longer, less rounded and not so heavy when viewed from the side, when viewed dorsally, meeting at a more acute angle. The basal antennal joints, while somewhat vari- able may prove to be of some value; in general, the third joint is subequal to the second, both together being equal to the first, the fourth being one-third as long as the third. The shape of the prosternum^ while somewhat variable, seems to be constant enough to be of some value, at least in separating the forms from any one region. It is divided into a large basal plate, with wing-like lateral areas separated by postero-lateral notches and a shallow longitudinal groove, and a smaller anterior plate, separated from the basal by a deep groove. Basal plate large, flat, truncate posteriorly; lateral notches quite sharp; grooves between the middle and lateral plates shallow and ill-defined; lateral plates rather sharp, narrowing anteriorly; anterior plate smaller, posterior margin regu- larly arcuate, postero-lateral angles evenly rounded, the whole lateral and anterior margin forming an even curve. In some specimens the anterior plate is semicircular, and in a few the anterior margin is squarely truncate, but in the majority of cases this plate is not more than twice as wide as long, and in many cases is noticeably less. Stridulating organ * consisting of very small, raised, chitinous plates on the inner surface of the hind femora, compactly grouped on the basal portion of the femur near its upper or anterior margin; these plates arranged in rows which may be either straight or slightly wavy, the direction of the rows being at an angle of about 30 degrees with a line connecting the coxa and base of tibia (vertex of the angle toward the coxa); the width of the rows varies from 10 to 12 microns, but this variation cannot be correlated with age. In young or recently moulted specimens the plates rise to a blunt point on their free mar- gins; in older specimens wear has reduced the free margin to a smooth flat curve, or to a straight line. The plates are in contact with one another laterally. Maximum Minimum Mean Length of hind tibiae, 2 17.0 mm. 12.0 mm. 15.0 mm.

News, vol. xxxiv, No. 3, p. 74) figured the differences in stridulating plates as a sexual difference in S. longispina Brunner. Since we find both of these types of plates in both males and females this cannot be a sexual difference. We would place his female (fig. B) in S. intermedins and his male (fig. A) in s. fuscus. Duncan’s figure B resembles very closely the stridulating plates of specimens from Pasa- dena, which superficially resemble 5. fuscus. 178 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 Stenopelmatus intermedius Davis and Smith, n. sp. Punctuation of head sparse, the lines of punctures barely attain- ing the vertex; a diffuse finer punctuation over the whole frons in addition to the coarser punctuation of the sutures and punctate lines. Angle of junction of the frontal suture somewhat more acute, the oblique arms curved, their apparent ending being above the insertion of the basal antennal joints, the sutures themselves very fine and even. Rugose area above the fronto-clypeal suture somewhat larger in proportion, the rugosity transverse rather than oblique. Third basal antennal joint longer than second, both together being sub- equal to the first, the fourth one-third as long as the third. Ovi- positor of female shorter, stouter, more rounded, more abruptly curved upward as seen from the side, the blades meeting at a more obtuse angle (about 40-45 degrees) as viewed dorsally. Basal plate of prosternum fairly large, the postero-lateral notches wider and more rounded; posterior margin squarely truncate in the female, evenly rounded in the male; lateral plates wider in proportion^ not so much narrowed anteriorly, the posterior angles directed more laterally; anterior plate narrow, at least two and one-half times as wide as long, its posterior margin regularly arcuate, the anterior usually squarely truncate, sometimes rounded. Stridulating organ occupying the same location on the hind femur as in S. fuscus ; plates arranged in rows but the rows not as distinct. It is not possible to assign a definite line of direction to these rows since the plates are more or less equally spaced, and seem aligned in several directions. Width of the row (measured from the free margin of a plate to the free margin of a plate in the adjacent row) varying from 14 to 20 microns; variation in width of a row not correlated with age; free margins of the plates smooth curves, far more strongly arcuate, without a blunt tooth arising at the crest of the curve; not reduced to a straight line by wear, each plate standing apart from all its neighbors, with no contact laterally; the distance between plates varying from 2 to 4 microns. Fine secondary punctuation of the frons almost lacking in some specimens; in most with a fine sculp- ture, the result of scratching by earth particles while digging. Length of the basal antennal joints varying, the third, in some cases, being subequal to the second and the fourth from one-fourth to one-third as long as the third. In some specimens (especially males) the pos- terior margin of the basal plate of the prothorax is rounded, but in most cases it is squarely truncate, and in some specimens it may be slightly emarginate. The anterior margin of the anterior plate is also subject to some variation, but in all cases observed is at least slightly truncate.

Three pairs of paratypes from the same locality are to be deposited, one pair in each of the three following museums : United States National Museum, Philadelphia Academy of Natural Science, and Entomological Department of the University of California. These specimens were undoubtedly mature, since they suc- cessfully copulated before they were killed. This species might at first be taken for a form intermediate between 6'. fuscus and S', pictus. According to the characters of Hebard’s table it would come under S', longispina, the spination of the hind tibi^ being the same as that given for that species. In size and general appearance this species more closely resembles S', pictus, except that the dark lines on the front are lacking. Stenopelmatus pictus Scud. * Heavy punctuation of the head practically lacking, the secondary punctuation extremely fine and sparse. Frontal sutures much as in intermedins, as is the rugosity above the fronto-clypeal suture. Basal antennal joints about the same, except that the fourth is only one- fourth as long as the third. Ovipositor of the female longer, less stout, the angle formed by the joining of the apices of the blades more acute. Basal plate of the prosternum somewhat arcuate pos- teriorly, the lateral plates quite wide, their posterior angles rounded and not laterally directed. Anterior plate very transverse, about seven times as wide as long, fairly regularly arcuate posteriorly^ sinuately truncate in front. * Since these notes were prepared we have had an opportunity to examine a specimen of S. pictus from Suisun, California, sent by Dr. Stanley Freeborn, and a series of eleven specimens taken in lower Panoche Canyon, Fresno County, California, by Mr. F. W. W''ymore and Dr. E. C. Van Dyke. The specimen from Suisun agrees closely with the characters stated previously. Those from Panoche Canyon agree in all except the shape of the anterior prosternal plate, which, in this series, varies from transverse and very short to nearly triangular; the black markings of the head and thorax, however, are very distinctive. This species on the whole is some- what larger than S. intermedius . As these specimens were all dead when received there has been no opportunity for observation of habits and mating reactions. 180 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

There are no specimens available from which to make slides of the stridulating plates, but it is to be expected that these would resemble those of intermedius quite closely. The only specimen of .S’, pictus available for examination at present is a female in the collection of the California Academy of Sciences, taken by E. P. Van Duzee in San Francisco, April 11, 1919. This specimen was determined as pictus by Hebard in 1920 but is marked “atypical.” The presence of the dark lines on the head serve, however, to distinguish it immediately from S. intermedius. Preparation of Soft-Bodied Insects In mounting such soft-bodied insects as Stenopelmatus (Orth- optera) for the cabinet, it is found that great difficulty is expe- rienced in preventing the abdomen from shriveling to such an extent as to be useless for measurement or other identifica- tion, Removing the viscera through a ventral longitudinal suture and filling the abdomen with cotton has been tried, with indifferent success. I have found that by injecting the speci- men hypodermically with 95 per cent alcohol and then immers- ing in alcohol of the same strength for a month or six weeks, very satisfactory results may be obtained, the abdomen shrivel- ing only to a very slight extent. Formalin or some other rap- idly hardening agent might be used with about the same or a little better success. — Alonzo C. Davis. After a recent severe outbreak of the oak moth (Phryganidea calif ornica) at Mill Valley, California, I placed a handful of the chrysalids in a container. At one average inspection there were five moths and fifty parasites (Ephialtes hehrensi Cress.) in the box. Later some small Tachinids and a few Chalcu ovata emerged. This would indicate a high rate of parasitism. — E. P. Van Duzee.

Un- fortunately, the receptaculum seminis in the type is almost destroyed. Rothschild, comparing a series of Anomiopsylhts niidatus which he had from Paradise, Arizona, with the type of californicus came to the conclusion that calif ornicvus was the same as nudatus. These fleas are certainly very much alike but there are minor differences in the shape of the receptaculum seminis (fig. 5), and discovery of the male of calif orniais shows Rothschild to be in error when he pronounced californicus to be a synonym of nudatus. In both species there are three small spine-like bristles on the finger of the claspers. In californicus these are arranged close together in an oblique row near the apex of the finger (fig. 9, F). In nudatus they are much more widely separated along the posterior border of the finger, two of them above and one far below. Hoplopsyllus powers! Fox, n. sp. Figs.

Soc., XVI, 88, Pseudanarta. Described from specimens from Colorado, Mead and Henry Edwards. Beutenmueller, 1892, Bull. Am. Mus. Nat. Hist., IV, does not list a type in the American Museum of Natural His- tory. Hampson, 1906, figures the species and lists a female type in the British Museum. We possess a specimen compared with this type by Dr. J. McDunnough. The species has been correctly determined in collections, but all authors appear to have overlooked the fact that it has hairy eyes and therefore does not belong in the Cuculliinse, but falls into the Hadeninse. By Hampson’s keys, 1905, Cat. Lep. Phal. B. M., V, it would run to the genus Trichestra Hamp., but appears to be there out of place. The genera of the Hadeninae need revision, so we tentatively place the species with its allies secedens Wlk. and hasivirida B. and McD. The three agree in possessing yellow basal areas on their secondaries, and lashed eyes, but differ considerably in characters of palpi and vestiture. It is probable that three distinct genera will ultimately be erected for these three spe- cies, but for the present they can rest in 1 Sense Hampson, 1905. We are cognisant that PoUa is a Tentamen genus with type flavidncta, belonging to the subfamily Cuculliinse; merely republished by Ochsenheimer, 1816, who credits to Hiibner. Hampson, 1907, Ann. Mag. Nat. Hist., (7), XIX, 252, uses Miselia, with type desig- nated as conspersa, in place of PoUa. But Miselit! is also a Tentamen genus, with type oxycaniha, belonging in the subfamily Cuculliinae; merely repub- lished by Ochsenheimer, 1816, who credits to Hiibner. Like most European workers, Hampson has refused to accept generic names unless they were accompanied by a description in words, and not only rejects the Tenta- men, but also the genera of Ochsenheimer. He, therefore, lists both Folu and Miselia from Treitschke, 1825. Probably the correct generic name for the bulk of the species placed by Hampson in PoUa, or Miselia, will be Hadena Schr. 188 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

A NEW SPECIES OF PLASTOCERID.E IN THE GENUS EUTHYSANIUS (COLEOPTERA) BY VASCO M. TANNER Brigham Young University, Provo, Utah In 1853 Dr. John L. LeConte established the genus Euthy- sanius and described the species lautus as the type of the genus. In 1866 he described the species pretiosus, which was the second of the two species in this genus. These descriptions are brief and rather inadequate because important morphological charac- ters are ignored. The genitalia of these species, for example, have valuable characters which may be utilized in separating them. Some of the recent workers in coleopterology have failed to base their descriptions upon definite morphological charac- ters and as a result their descriptions are almost worthless. It seems much safer to work with many morphological characters than to split up groups and make new species on a few variable characters. Euthysanius blaisdelli Tanner, sp. nov. (Figs. 2, 4, 7, 8 and 11) Material studied : Three males, collected by the writer and Mr. Angus M. Woodbury in Zion National Park, Utah, August, 1925. Male. General color a rather light brown.

II, NO. 4 (fig. 7) rather large with numerous stout setse on the dorsal outer margin; antennae (fig. 8) pectinate, very pubescent, reddish brown throughout; pronotum almost square, except for the posterior outer margins which extend back to the humeri (fig. 4) ; elytra about three times as long as wide, almost parallel, bearing numerous small pale setae; legs long and slender, of uniform chestnut brown color; abdo- men long and slender, the ventral side densely covered with small setae, segmentation clearly discernible, there being ten tergites and ten sternites present; aedeagus leaving the body between the ninth and tenth sternites; genitalia (figs. 2 and 11) much like that of E. pre- tiosus Lee. (figs. 3 and 12). In this species the ninth sternite is emarginate; in E. pretiosus Lee., to which it is most closely allied, it is not emarginate. The inner surface of the tegmen is very different in these two species, as is also the basal piece. The genitalia (figs. 1 and 10) and the antennae (fig. 9) of E. lautus Lee. are noticeably dis- tinct from those of the other two species. Type, male, (No. 21) in my collection.

Child’s Glacier and Seward, Alaska, all taken by the writer. The Seward example is stouter than the others and is doubtless a female. This species does not fit well into any of the groups indicated by Horn. Because of its depressed form it would by Horn’s table be likely to be referred to the striatulus group, but the sculpture is much more in harmony with the melsheimeri group, where I think it may for the present be placed in the vicinity of tumescens.

The placing of lugubris as a synonym of tene- brosa in the Leng List is also an error, the former having the intermediate tibiae of the male simple, whereas in tener brosa they are toothed.

Described from a single female taken by the writer at Daw- son, Yukon Territory, June 26, 1924. This is the first entirely black Trogoderma to be described from our fauna. I have in my collection a pair (62) of similarly black specimens from Aweme, Manitoba, which are probably specifically identical, but of this I do not feel entirely assured. They are considerably smaller (2.8-3.25 mm.) and seemingly a little narrower, the antennae entirely rufous, the third joint very small in the male. Perimegatoma perversa Fall, n. sp.

Head two-fifths as wide as the thorax, the latter moderately strongly transverse; sides arcuately narrowed from the base, side margins narrowly refiexed. Elytra about three and a half times as long as the thorax, sides broadly sinuate before the middle. Head and thorax coarsely and densely variolate-punctate, elytra a little less coarsely and densely so, the punctures subasperate toward the base, especially at sides. Body beneath similarly densely rather coarsely punctured, more rugosely so anteriorly.

Length, 4.6 mm.; width, 1.8 mm. Dawson, Yukon Territory; a single specimen. The antennal club is rather of the male type, but I am not sure that the specimen is a male. This species, by good rights, should be either the cylindrica of Kirby or Maiinerheim’s angularis, but in cylindrica the body is said to be very minutely punctured and covered with decum- bent cinerous hairs, and angularis is also said to be griseo- pubescent and with condensed white hairs on the hind angles of the thorax ; absolute statements which are quite at variance with the present species.

Of cyclophorus he writes “has the whole of the lower surface and legs light red, but as the elytra are not quite black I think that very likely indi- cates immaturity.” Of concolor (type) he remarks: “Has very faint traces of two series of small spots placed as in cyclophorus.

Specimens taken at Anchorage are with- out hesitation referred to this hitherto unrecognized species. I have little doubt that fulvipennis Mann, is iden- tical. Renewed study at this time enables me to say that the species that I described ^ under the name armatulus is the true costicollis of LeConte, while my montamis as indicated above seems not to differ from cinnamopterus as now identified. This leaves the species which I had previously supposed to be costicollis without a name and for this the name carinifer is now proposed. Making these changes in name the characters as given in my table apply, except that I was in error in saying that the front thighs are not toothed at base in the male of montamis. This tooth is very small but detectable in the type on renewed study ; it is a little better developed in an Alaskan specimen.

McKinley Park Station, Alaska, June 9, 1924, one male (type), two females. The specimens were beaten from an old bear skin found at a deserted camp a short distance south of the station. This species by its characters would fall between rudis and varicolor in my table (Trans. Am. Ent. Soc., xxvi, 1899, p. 148). The punctures of the elytral striae and interspaces are scarcely more unequal than on rudis, but the form and facies are more nearly that of varicolor. From both the present species differs by its larger prothorax with sides only very feebly serrulate, and by its much longer last ventral of the male. *Corticaria cavicauda Fall, n. sp.

The type is a male and is one of a series of specimens taken by the writer on a spruce wood pile at Sheep Creek on the Yukon River below Eagle, Alaska, July 1, 1924. The same species was taken at Dawson, Yukon Territory, and there are other Alaskan examples in my collection from Ruby (Kusche) and Kowak River (Grinnell). The specimens from the last named locality are referred to by me (Ent. News, 1900, p. 459) 202 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 as T. cinnamopterum, and were reported to have been “thawed out of birch wood. Notwithstanding the indicated difference in habits, the specimens are undoubtedly all of one and the same species and cannot well be referred to any of our hitherto described species, though by description evidently closely allied to parvulum Csy. The latter seems to have a similarly polished and sparsely punctate prothorax, which, however, is said to be as wide as the elytra, a condition not obtaining in any one of twenty examples before me. Parvulum moreover was described from Indiana and it is improbable that it can be the same as the Alaskan species. ^Criocephalus agrestis Kby. Fort Yukon and Rampart (Kusche).

Narrowly elongate, feebly cuneiform, entirely black, finely sparsely cinereo-pubescent; head and thorax dull, elytra moderately shining. Antennae ( 6 ) slender, as long as the entire body, pectinate, second joint very small, third with an acutely triangular process, shorter than the joint itself; rami of following joints very slender, becoming gradually longer, those of joints 6-10 fully twice as long as the joints themselves. In the female the antennae are stouter, attaining the apical third of the elytra, serrate from the fourth joint. Head except the clypeus densely punctate; eyes deeply emarginate, strongly promi- nent in the male, in which sex they are separated on the front by about three-fourths the length of the basal joint of the antennae; in the female a little smaller and distant by about the length of the basal joint. Prothorax moderately transverse, trapezoidal, sides nearly straight and strongly convergent throughout; a feeble post-median sinuation; base with a short truncate median lobe, surface very densely punctate and dull throughout. Elytra about seven-tenths (6) or one-half (9) longer than wide; sides gradually and feebly divergent; striae fine, finely punctate, all abbreviated at apex, the APRIL, 1926] FALL ALASKAN COLEOPTERA 205 fifth and sixth shortest; intervals flat, not distinctly punctate but with fine scratches and reticulations. Pygidium a little wider than long, parabolically rounded at apex, impressed each side at about the middle, finely but not very distinctly punctate. Body beneath closely punctate anteriorly, becoming more sparsely and finely so on the ventral segments. Legs very long and slender, slightly less slender in the female; the hind tibiae in the latter sex with a very short acute mucro at tip, which is almost completely obsolete in the male; hind femora without teeth or denticles; basal joint of hind tarsi conspicu- ously longer than the remainder in both sexes. Dimensions: male (type), 2.2 x 1 mm.; female, 2.5 x 1.3 mm. Described from four examples (1 6, 3$ 9 ) taken by the writer in the sweepnet near McKinley Park Station, Alaska, June 9-10, 1924. This very remarkable species is not only notable as being the first of its family to have been reported from Alaska, but it is one of the most conspicuously distinct species in the North American fauna. By its simple femora and pectinate antennae it must be referred to Horn’s Group IV, from all the members of which it differs signally in its narrow form and the long antennae of the male. FAMILY CURCULIONID^ *Apion alaskanum Fall, n. sp. Moderately robust and ventricose; black, antennae, except the club and one or two joints preceding, front tibiae and all the femora except at tips, yellow; body above thinly^ finely cinereo-pubescent, scarcely shining; meso- and meta-sternum at sides densely clothed with ap- pressed white hairs. Beak ( 9 ) subequal in length to the head and thorax, rather slender, thickened in basal third, which is distinctly punctured and dull, finely sparsely punctulate and shining beyond the antennal insertion. First joint of antenuje as long as the next two, second reaching the eye. Front canaliculose; eyes prominent. Prothorax very little wider than long, sides parallel in basal half, thence oblique and nearly straight to apex; basal margin not at all expanded, surface densely, rather coarsely, punctate; median line impressed in basal third. Elytra widest at apical two-fifths, twice as wide as the thorax; humeri moderate, sides divergent and nearly straight from base to middle; interspaces flat, nearly twice as wide as the striae at the middle, sub-biseriately punctate. Beneath rather coarsely and densely punctate. Length (excluding beak), 2.25 mm.; width, 1.2 mm. Described from a single female specimen taken by the writer on the Yukon River, Alaska, thirty miles above Fort Yukon. This species belongs to my group IV, and by the table is to 206 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

The latter species differs in many respects, notably in its more conical thorax with expanded basal margin, parallel elytra, much longer beak, smaller, not promi- nent eyes and punctate rather than channeled front. Only one species of Apion ( cuprascens Mann, from Sitka) has hitherto been reported from Alaska. '^Sitona tibialis Hbst. Skagway. Lophalophus inquinatus Mann. Skagway. Lepidophorus lineaticollis Kby.

Above thinly clothed with slender linear yellowish gray scale-like hairs, with scattered broader white scales on the elytra which show some tendency to a serial arrangement; the sides and median line of the prothorax and an elongate scutellar spot more densely scaly; beneath clothed with larger oval, more or less pointed gray scales which are densely placed anteriorly, a little sparser and more oblong in shape on the abdomen. Head densely punctured; beak slender, striate and finely punctate; antennal funicle seven- jointed, formed as in pusio. Prothorax wider than long, much nar- rowed in front, lateral tubercles small but acute, median line feebly channeled, apical margin nearly straight between the broad and very feeble angulations, disk very densely punctate throughout. Elytra one-fifth longer than wide; humeri moderate, sides more or less evi- dently convergent from the humeri; intervals rather wide, nearly flat, subrugose, each with a series of acute tubercles on the declivity. Legs slender, femora unarmed, claws simple. In the male the middle and hind femora are unguiculate and the last ventral segment is deeply transversely foveate; in the female the tibiae are unarmed, the last ventral similarly but much less strongly impressed. Length (type), 2 mm,; width, 1.15' mm. Described from a series of specimens of very uniform size, taken at Nenana, Alaska, July 6, 1924, and a single specimen from Fort Yukon, July 2. The type is a male from Nenana. « This species greatly resembles pusio Mann., which occurred plentifully at Anchorage. In the latter the claws have a very small basal tooth (which may easily be overlooked), the scales of the elytra are more or less aggregated in small spots, giving a mottled aspect. Fulvotertius must be referred to the squama- tus group of Dietz, and by its characters seems to fall next to squamattis , which, however, it does not much resemble. Pelenomus gracilipes Dtz. Dawson.

In the present species the strial punctures are evidently smaller, the intervals between the striae always distinctly wider than the punctures themselves. The sides of the prothorax are slightly more rounded than in nigrinus, and the ros- tral Carina is always sharply defined and entire. In my series of nigrinus the rostral carina is never so well developed as in yukonis and not infrequently is nearly or quite obsolete except for the short distance where it crosses the apical convexity. Length, 4.3 to 5.6 mm.; width, 1.55 to 1.85 mm. Dimensions of type, 1.7 x 4.6 mm.; of prothorax, 1.5 x 1.3 mm. Described from six examples taken in flight at White Horse (June 21, 1924), and Dawson (June 24, 1924), Yukon Terri- tory. The type is a male from White Horse. In the male the last ventral is apically concave and furnished with a brush of yellowish erect hairs as in the allied species. Notwithstanding the rugose sculpture the integuments of the upper surface are polished and shining throughout, without trace of alutaceous sculpture. Nigrinus is a little duller though not visibly alutaceous ; the nearly allied macer, on the other hand, has the surface between the punctures distinctly alutaceous.

APRIL, 1926] BEAMER GRIBURIUS 209 NOTES ON GRIBURIUS MONTEZUMA (SUFFRIAN) (COLEOPTERA-CHRYSOMELID^) BY R. H. BEAMER Department of Entomology, University of Kansas, Lawrence The University of Kansas Biological Survey party on July 5, 1923, accompanied by Mr. Warren Knaus of McPherson, Kan- sas, visited the salt-marshes and surrounding hills in Kiowa County, Kansas. On the roof of a cave in a rocky bluff a large series of Griburius montezuma (Suffrian) was taken. The cave extended back into the cliff perhaps eight feet, and was two feet in diameter at the smallest place. Quite a large number of sticks and much debris was piled up at the farther end, upon which were two young buzzards. The stench which accompanies a buzzard’s nest was not lacking. The specimens of Griburius were found mating in large numbers on the roof of this cave. Some were also observed flying in and out. A small den with two openings and a stick nest at the back of it was also a favorite place with the beetles. This second place was perhaps ten feet from the first, along the same cliff. As this particular species was considered a good find by Mr. Knaus, a good deal of interest was taken in the actions of the individuals and their seeming preference of location. We then searched all the caves, shady cliffs, crevices, and all other places in that immediate vicinity, but not a single specimen could we find. On July 12, 1923, however, in Ellsworth County, Kansas, perhaps seventy-five miles north and fifty miles east of the first locality, another buzzard’s nest cave was found and here four more specimens of this same species were taken. This called forth a further search of all the caves in the vicinity, but no more specimens were found. In the rather hasty examination of the debris about the nests no larval cases or other indications of the insect’s life history were found at the time of our first visit. This preference, how- ever, for a very definite location for mating and the knowledge that some closely related forms are scavengers in ants’ nests led us to suspect that this beetle did pass its early stages in the 210 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 refuse of rodent or buzzard nests. It was with a great deal of interest, therefore, that we made our second visit to these same caves in Kiowa County, Kansas, on April 12, 1925. We were rewarded by finding both the living larvae in their cases and the old cast-skins of previous generations. The sandstone in which the caves occur is friable and the walls about the entrance have been honeycombed in the process of erosion. It was in these small holes and under stones at the mouth of the caves that the larval cases were found. About three dozen cases were collected. The beetles emerged in due time, but the attempt to obtain the life history failed, for the specimens all died before laying eggs, although two pairs were observed to mate in captivit^c The evidence is conclusive that they overwinter as larvae, and is suggestive of but one genera- tion a year. Thanks are due to Mr. H. C. Fall of Tyiigsboro, Massachusetts, for identification of the species. A Luminous Zarhipis (Coleoptera) On April 3, 1926, an adult male of Zarhipis riversi Horn (?) was examined with a view to finding out whether or not it pos- sessed the power of luminosity. The insect was taken into a dark room and, when excited by shaking and moving about, was observed to be distinctly luminous. So far as could be deter- mined in the dark this luminosity involved the posterior and lateral borders of the first, second and third abdominal segments dorsally, and the sides, apparently just back of the spiracles, of the remaining segments. The light was greenish yellow and, though faint, could be seen at a distance of about two feet. The insect seems to have at least partial control over this power, as it was luminous only when disturbed and then shone steadily for some time. Later in the day the insect failed to show any light, no matter how much it was agitated. Another male taken on May 3 refused to become luminous at first, but after several trials over a period of about four hours it shone very feebly for a short time. The females of this genus are distinctly luminous and apparently do not have any control over the light, as they glow steadily. — A. C. Davis. APRIL, 1926] ESSIG BUTTERFLY MIGRATION 211 A BUTTERFLY MIGRATION BY E. O. ESSIG A true migration of the thistle butterfly, Vanessa cardui (Linn.), occurred in California from the middle to the last of March, 1926. Large numbers were first noticed in southern California about March 10. They were rapidly traveling north and entered the southern end of the San Joaquin Valley on the 12th and 14th. On the 17th they were in the Sacramento Valley, and a portion of the flock passed through Berkeley on the 23rd, 24th and 25th. In the latter place all were traveling due north. In the orchard districts the butterflies were attracted to the opening blossoms of almonds, apricots, cherries, plums, prunes and pears, all of which had an unusually heavy bloom this year. Many of the farmers were greatly annoyed by their presence. In the interior valleys the butterflies were hovering over the plants commonly called “woolly breeches” {Amsinckia spp.), which is a favorite food plant of the caterpillars in the West. A full explanation of the periodic migrations of this and a closely related species, Vanessa carye (Hiibner), has not yet been made, but they are somehow connected with years having mild, dry winters. Temperature is undoubtedly an important factor, and the continued hot weather during the month of March in California, Arizona, and northern Mexico may have started the species north. These migrations are always toward the coast or in a north- erly direction, and no return migrations have been noted. Many of the butterflies were captured, and their badly battered wings gave evidence of a long flight. They move rapidly and often cover from 100 to 200 miles per day. They rest at night and the maximum flight occurs from 2 to 3 p. m. on bright, hot days. On cold days the forward movements cease, so that the limits of the flights are probably also determined by temperature. Note by the Editor — Mr. W. S. Wright of the San Diego Museum of Natural History writes me that this migration was observed throughout southern California from Yuma to San Diego, beginning March 13, the general direction of the flight being from southwest to northeast, and the “peak” of the flight lasting about 40 minutes. 212 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 The butterflies were seen feeding at Encelia flowers. Mr. Wright noticed that the flight followed two days of strong wind from off the desert, and suggests that probably the butterflies were blown from the desert toward the west until they came into contact with the cool air from the ocean and were then deflected toward the northeast. Mr. Wright noted that the flight of two years ago was also preceded by a strong wind from off the desert. A NEW NOMADA BY C. L. FOX San Francisco, California Nomada (Gnathias) klamathensis, C. L.

DOANE Stanford University During the past few years the common mealybug, Pseudo- coccus gahani, has been becoming more and more abundant and destructive on the ornamental plants on the Stanford Campus. Efforts were made to control it with the usual spray- ing materials, such as some of the miscible oils, Blackleaf 40, and soap solutions, but none of these seemed to do the work satisfactorily. It seemed almost impossible to get the oils to penetrate the cottony secretion that often covered the masses of these insects when they were abundant on any particular plant, and even when the insects could be hit individually with the spray, they were not always killed. The same factors seemed to keep the nicotine from giving a good killing. It was found that the soap mixtures would dissolve this mealy covering but that they would only kill a part of the insects. After a series of experiments in which these different sprays, used singly and in combination, were tried out, we finally hit upon a combination which has given us very satisfactory results here on the campus. I have not had an opportunity to make any extensive tests to determine the most economical combina- tion of these materials, but as soon as I found a combination that would do the work I began using that as I was more concerned in getting results than in keeping down the cost. It is quite possible that less nicotine or less soap might be used with equally good results. The combination that I now use is as follows : 1 gallon Volk Oil, formerly known as “orange oil.” lbs. Gold Dust Washing Powder, pint Nicotine (Blackleaf 40). 50 gallons Water. It seems that the efficacy of this combination depends upon the fact that the soap solution will cut the secretions which are covering the insects and the nicotine will then be able to reach and destroy the insects, and the oil helps to make the material penetrating. It has been used successfully on many kinds of 214 THE PAN-PACIFIC ENTOMOLOGIST [vOL. II, NO. 4 ornamental plants, particularly Choisya, Oregon Grape and Pittosporum. In cases of very bad infestations we have some- times found it necessary to make a second application before the plants were thoroughly cleaned. One application on a badly infested lemon tree gave very good results. Some of the large Araucaria on the campus were very badly infested with the golden mealybug, Pseiidococciis aurilanaHis. At a time when many of the young mealybugs were wandering over the leaves these trees were thoroughly sprayed with this same material, using a spray-gun with a pressure of 250 to 300 pounds. This greatly improved the appearance of the trees and killed most of the mealybugs, but another treatment was necessary some weeks later as it was found that all of the insects had not been reached at the time of the first spraying. One of the great advantages of using this spray is that it removes from the tree the sooty mold that grov/s in the secretion of the mealybugs. This, of course, makes the trees much brighter and cleaner. AN ENTOMOLOGICAL CODE The Entomological Society of London has sent out a sug- gested entomological code compiled by the British National Committee on Entomological Nomenclature. The adoption of such a code, especially if approved by the International Com- mittee on Zoological Nomenclature, would be a great help toward unifying the nomenclature of our science. Most of the thirty articles in the proposed code will doubt- less meet with the hearty approval of American entomologists, but one or two might with advantage be slightly modified. Article 14, for instance, provides that names of a lower rank than that of a subspecies shall have no status in nomenclature. The term “variety” is not even mentioned in this code, but it has been, and still is, largely used by certain entomologists, and we are left in doubt as to its standing under the proposed code. Frequently it is used in the sense of subspecies and in any case cannot be ignored. For many years such names must be APRIL, 1926] VAN DUZEE ENTOMOLOGICAL CODE 215 given subspecific rank or our nomenclature would soon be in a condition of chaos. -Article 20 provides that the law of priority obtains when any stage in the life history of an insect is named before the adult, a provision that opens the road to abuses that might easily prove intolerable. Article 23 provides that if a genus is established without the mention of a species the first reviser has the right to select any species as the type, provided it agrees with the original definition of the genus. Most American students would accept this but would credit the genus to such reviser, a proce- dure not mentioned but probably intended by this code. So long as we employ genotypes for the final delimitation of our genera, it is illogical to accept any generic concept that contains no species that can be used as its type. If we are to accept genera on their described characters alone, the naming of a genotype is a superfluity, and that way lies chaos. With such a rule there would be nothing to prevent any adventurer from naming up a series of genera by assembling imaginary characters and awaiting the discovery of some insect that would fit into his concept. The correct naming of genotypes is probably the most perplexing problem in nomenclature. There are cases such as Myodocha Latr. where it is quite impossible to name a geno- type without violating some rule of our zoological codes. In such cases we must use common sense and possibly depend upon later validation by some authoritative committee. The constant splitting up of genera is a form of amusement quite popular with a certain class of our entomologists. In many cases these minute subdivisions, of both genera and spe- cies, are but minor offshoots in a still plastic complex, that soon will become extinct in the natural course of evolution, but for the present they may be treated as subgenera or subspecies, and thus serve a useful purpose in classification and at the same time be ignored by the worker in economic entomology. It is conceivable that to the student of evolution a few hundred years hence the description of such minute subdivisions may prove of the greatest value, while to us they are but a weari- • ness. It is for us to select what we wish to use and leave the rest to posterity. — E. P. Van Duzee. THE PAN-PACIFIC ENTOMOLOGIST Published quarterly by the Pacific Coast Entomological Society in co-operation with the California Academy of Sciences E. P. Van Duzee, Editor F. E. Blaisdell, M. D., Treasurer The present number of the Pan-Pacific Entomologist closes its second volume. The subscription list has shown a steady growth during the year, and the third volume will start under much improved conditions financially. For the completion of this volume there was still a considerable deficit to be made up. Members of the Pacific Coast Entomological Society have con- tributed a part of the necessary funds, but the bulk of the deficit was covered by a very generous check received from Mr. B. Preston Clark and an emergency appropriation from the funds of the Department of Entomology of the California Academy of Science. Twenty- four extra pages, issued with Vol. II, to cover two papers of unusual length, were paid for by the authors and other friends of the journal. The numbers of this volume have been mailed as follows: No. 1, August 27, 1925; No. 2, January 16, 1926; No. 3, May 8, 1926; and No. 4, July 14, 1926. Among recent visitors at the entomological department of the California Academy of Science may be mentioned Mr. M. C. Van Duzee of Buffalo, New York; Dr. Carl J. Drake of the Iowa Agricultural College; Mr. P. H. Timberlake of the Citrus Experiment Station at Riverside, California; Mr. Otto Swezey of the Hawaii Sugar Planters’ Association; Mr. G. M. List of the Colorado Agricultural College ; and Prof. T. D. A. Cock- erell of the University of Colorado. Mr, Van Duzee spent several weeks working over certain families of the Diptera in the Academy collection that were in need of revision ; Doctor Drake studied our Tingids, Anthocorids and Gerrids, and Mr. List our Cimicids. Dr. and Mrs. E. C. Van Dyke left June 3 for two months’ collecting in the mountains of Colorado. Mr. C. L. Fox has gone to England for a visit at his former home at Plymouth, returning in October.
