This striking form was described from Mexico and is not in our lists. It is easily distinguished from any other species in North America by the shining lead gray wings, with the base of the fore wing dusted with white.

METHODS OF COLLECTING, MOUNTING AND PRESERVING HEMIPTERA BY J. R. DE LA TORRE-BUENO, White Plains, N. Y. The great impetus received in this country of late years by the study of Hemiptera, particularly the Heteroptera, makes it desirable, indeed necessary, to have more precise directions for collecting and mounting them for study than are to be found in the text books, or even in directions for collecting insects in general. Indeed, but too often the sole direction or indication is that they may be secured by the same methods as Coleoptera, “q. v.” While these present directions refer in a restricted manner to the Heterop- tera, nevertheless they apply equally well to the Homoptera, particularly the leaf-and-tree-hoppers. In fact, greater numbers of Homoptera are likely to be taken than of Heteroptera, both in point of species and of numbers. Those directions which refer us to methods for Coleoptera of course go no further; they say nothing as to their efficacy, nor as to the methods which may be best adapted to each family. Times, places and conditions are equally omitted. What follows endeavors to fill these deficiencies, intelligently and practically, giving the methods best adapted to each group and how to apply them successfully. The best form of the necessary apparatus is also set forth. APPARATUS THE KILLING BOTTLE. First is the classic cyanide bottle. There is the common or garden variety, adequately described in any entomology or directions, for whose preparation need not be repeated. Such bottles may be purchased ready for use, of any size and shade, from any dealer in entomological supplies. There are also various homemade sorts, each quite good and even excellent, according to the skill and care with which it is prepared. In course of time and with experience, another form has developed. For Hemiptera this is any stout tube or bottle, about 4 to 6 inches long and at least 1 inch at the mouth, inside measurement, but it need not be bigger than 1% inches. The ordinary tall’ screw-top jars in which candy is now put up are excellent and strong, and the shoulder some have is quite a good feature. Large heavy test tubes, so-called ignition tubes, without a lip are also very good. Their length is a desirable feature, which prevents actrve insects from flying or springing out of a bottle not strong enough, or frequently opened in the field; or held open while a number of specimens are being put into it. Smaller tubes and vials are also convenient, where it is desired to collect some specimens separate from others. The other materials required to prepare the bottle are ;— Cyanide: Boric (Boracic) Acid, crystals or powder: Sawdust: Blotting paper or thin sheet cork cut in circles to fit the inside diameter of the bottle snugly: Newspaper or tissue paper. The Cyanide is broken up into bits about the size of a pea or smaller. A few of these are put in the bottom of the bottle, in proportion to its size. For example, in a bottle 114 inches in diameter, the Cyanide should be about ™% inch tr eo Wl an all en Un Tet 1° = 2 ao —_ = 45 4 oe \ CN. @ nH O&O oO mw ~* oM ov SNM RO FR SD o LVI. THE CANADIAN ENTOMOLOGIST 7 deep. A little water is added, care being taken not to wet the sides of the bottle. On top of this, about 1 inch deep put a layer of sawdust into which has been mixed the boric acid, about 1/3 as much as the cyanide in amount; for instance, 10 grains of boric to 30 of cyanide. A chemical reaction sets up, and if there is not too much water, a strong but gradual emanation of cyanogen takes place. Over all, put three or four disks of blotting paper cut to fit snugly, which will hold down the charge. A thin layer of absorbent cotton is put above this, tamped down with another couple of disks. Such a bottle is ready for use within a half hour. The cork for the bottle should be long, to make it easy to take out and put it. To support the insects, narrow (%4-% inch) strips of any absorbent paper, curled over the edge of a knife should be put into the bottle. The paper also absorbs any moisture the insects give off. A little of the curled paper should be packed down, not too tightly, and the rest put in loosely, about halfway up the bottle. When the insect falls in, it falls among the coils and seldom gets away. CARBON TETRACHLORIDE BOTTLE. The dangerous nature of cyanide has led to the trial of other killing agents, or narcotics, such as chloroform and ether. ‘Tetrachloride of carbon has been found excellent for this purpose, after extended use over a period of years. It is, however, claimed to change the color of Orthoptera, and must be used with caution for this order. I have not experienced this disadvantage in the case of Hemiptera. A wad of absorbent cotton is put at the bottom of the tube or bottle, wet, but not dripping, wih the tetrachloride. This is held in place by two or three blotting paper disks, or by one of thin sheet cork. it is well to put in another piece of cork or blotting paper about % to 34 inch above the charge to form a gas chamber. The upper partition may be held up by a short (34 inch) length of glass tubing slightly smaller than the inside dimension of the bottle or tube In hot weather evaporation of the tetrachloride is rapid and it condenses on the sides of the tube, wetting the insects. This gas chamber prevents the sweat- ing and makes the bottle last longer also. Such bottles are ready for use as soon as prepared and will last for quite some time—as much as five or six expeditions. To guard against loss of strength (which is always total, a small vial of the tetrachloride may be carried in the field for replenishing, which is done by just pouring in a little, sufficient to be absorbed by the blotter. This is not recommended as a regular practice however. These bottles have many advantages over cyanide. They are clean, absolutely harmless, not unpleasant in odor, easily prepared, full strength until completely exhausted; and from the point of view for their purpose, absolutely quick and efficient. A fly of any kind is inanimate by the time it reaches the bottom of tube; weevils succumb in about a minute and do not revive hours later when pinned. Insects may be left in overnight and will be quite flexible the next day. And finally, small, delicate forms may be put into smaller tubes, and the gas from the tetrachloride tube poured in (it being heavier than air). In this way Diptera, Mirids and other delicate forms may be kept separate and quite dry. 8 THE .CANADIAN. ENTOMOLOGIST JAN., 1925. Its characteristic of perfect harmlessness makes it ideal for the use of students and young collectors. Tetrachloride is cheap and easily obtained, It is not affected by the laws governing the sale of poisons. THE LIVE BOX Not all insects, of course, are collected for the cabinet. Many are secured alive for breeding and life-history work. ‘The collector should carry for these some suitable receptacle in which they may be carried ‘safely, comfortably and in good condition. For this purpese any tight tin box, not too large to go into a pocket will do, but some kinds are better suited to the purpose than others The best I have is a small box imported from France. It is oval and has a tight fitting lid hinged at one end, with a small trap door about 34 x 1% inches on top, through which to put in the insects. ‘To prevent insects already in from climbing out, the inside of the lid has a strip of tin abcut 34 inch high surround- ing the opening covered by the trap door. This extremely clever device prevents the insects already in the box from climbing or flying out each time the little lid is raised. Other boxes to be purchased from dealers have a small sliding door on the lid, not nearly so good a ‘device as the hinged trap-door. However, the least expensive and most easily obtained are the ordinary tin boxes in which 100 cigarettes are packed.. These nearly always have a hinged cover, are flat and easily slip into an outside coat pocket. For use, the box should have excelsior in it—very much. pulled: out—to give the insects something to cling to. Otherwise they will all came together in a’mass, if a number are put in the one box; or else a box will be needed for each specimen. Never put large and small insects in the same box or bottle. The larger are apt to damage the smaller. Tue Nets. THE SWEEPING NET (or bag). Above all other instruments of the chase, the sweeping net is the hemip- terists chosen and perfect tool. With it can be secured by far the largest num- ber of species and the greatest quantity of specinyens in any given locality. It can be used indifferently on herbage or trees, and only those few forms with special or restricted habitats fail to fall into it sooner or later. An afternoon’s collecting in the Eastern States, under average summer conditions should yield at least 100 specimens and 30 or 40 species, numbers likely to be much increased if the particular locality be favorable to insect life. It should always be taken into the field, in preference to any other implement, for even though out on a short ramble or for specific collecting, a tempting covert may be seen and tried. Many a rare species is secured by this adventitious employment of the sweeping net. There are many forms of the sweeping net recommended in entomological text books and various kinds may be bought ready made. None has seemed to me so satisfactory as that made by myself, which I have used now for over 20 years. This, in its simplest form, consists of a cylindrical bag open at one end, put on a net ring. A good handle I have found to be the ordinary 2-man ° LI Sé —e er LVITI. THE CANADIAN ENTOMOLOGIST ‘9 saw handle, to be bought at any hardware store for a quarter. Grooves should be made on the outside so the clips for the saw will hold firmly the ends of the net ring. An ordinary crabbing net ring with the pole cut off to a length of about 18 inches is as good a ring as can be bought. The general objection to ready made nets is their weakness and lightness. Sweeping is rough work but good exercise, and a certain amount of strength must be put forth. Where the sweeping is done along the tips of grasses, no resistance is met, but where the grasses are rank and lush, or when you sweep in among shrubbery and branches of trees, something is needed that will go through without being checked by the first thick grass-clump or gnarled branch or thorny bush; or perhaps even bent out of shape by the force necessary to work it effectively. To overcome these deficiencies the net I now use has gradually been evolved. My first sweep- _ing net was simply bound over the ring at the top. This soon wore out at the tront edge on the ring and had to be renewed at least once in a summer. In its present form the net is the usual bag of stout unbleached muslin—not canvas, which is too stiff. The mouth is bound about 1 inch deep with leather, with slots cut into the upper fold about every 4 inches. A copper or soft steel wire is run through this binding and split rings are then put on at the slots and over the net ring. Such a net lasts for years. It wears out at the front of the bottom, but it may be shifted on the ring to bring a strong section to the front. BUENO NET. Material: 4 ft. 3/16 inches soft steel rod; 2 doz. split steel rings % inch; 4 ft. thin copper or iron wire; 4 ft. strip leather, 4 inches wide; 2 yds. heaviest unbleached muslix 36 inches or 1 yd. 50 inches; I 2-man or cross-cut saw handle. : Construction: Bend the ends of the wire 4 inches from the tip at about right angles, then bend it to a ring, which may easily be done around any round post,—a kitchen table leg will do. When the ring is made, the straight ends should be parallel to each other. Adjust the ring to the handle and measure the circumference of your bag directly on it, allowing about 1% inches addition for seam; the strip for the bag should be about 15 to 18 inches wide, to allow for the depth of the bag and the top and bottom seams. For the bottom cut a circle about 2 inches more in diameter than the ring. The upper part of the bag is first sewn together and then the bottom put on. The leather band is folded in two and sewn to the upper edge of the bag with two or three rows of machine stitching. Any cobbler will furnish the leather and stitch it on. Notches are now cut in the upper folded edge of the leather at equal distances, say 3 or 4 inches apart. The thin wire is passed through and a split ring put on the wire at each notch, while the rings are on the net ring. Two shallow grooves are made in the handle alongside the hole and the straight parts of the net ring are put in. These are held tight by screwing in the wing nut in the handle. The net is now ready for operations. THE WATER NET. Many families of Heteroptera and a few Homoptera are found on or in the water. A water net is therefore a necessary part of the hemipterist’s outfit. Ordinary water nets are either too cumbersome or not strong enough, and a 10 THE CANADIAN ENTOMOLOGIST JAN., 1925. small strong net is thus very desirable. The wire to be used is the same as for the sweeping net, the straight bent ends are about the same length; and the net ring should be between 8 and 9 inches in diameter; the necessary length of wire is about 33 to 36 inches. The net proper is made of stout brussels net. The upper part binding around the ring is of heavy unbleached muslin and about 4 to 5 inches deep, the netting being about 4 inches deep only. Such a net as this is very strong and little likely to get tangled and torn on rocks or stumps in the water. The straight ends of the ring are put into a brass or copper tube about 4 to 34 inches inside diameter, the latter being the better size, and about twice as long as the straight ends. The latter are fastened into the tube by pouring in melted lead. To pre- vent this from running out, a short cork is driven in from the lower end until it touches the tips of the ring ends. Any stick about 6 feet long will do. In fact, any branch or stick of suitable thickness may be cut on the spot, if for _ any reason it is inconvenient to carry the proper handle. To prevent the net from being pulled off the handle, a small (% inch diameter) hole is drilled through the tube and an ordinary brass screw-eye is screwed into the handle though the hole. . Such a net as this, of a moderate size, permits its use in the water almost like a butterfly net in air; and this is very necessary in order to catch the shy and swift forms. It would not be possible to do this with the ordinary large and cumbrous nets generally figured. THE SMALL, WATER NET. For such small surface forms as Microvelia, Hydrometra, Menangata, the larger net is not efficient, as the size of the net prevents it from being put into small nooks, and the mesh of the netting lets the smaller bugs escape through it. An ordinary small kitchen wire netting strainer will answer the purpose, as to size and convenient short handle. But much better is to take off the wire netting and put on the ring a circle of ordinary cheese cloth cut large which iets it sag a little in the middle. Its uses will ‘be explained further on. THE UMBRELLA, . This implement cannot be made and is best to be purchased from any standard dealer. It is, of course, possible to buy a cheap stout cotton umbella and line it with white. And at a pinch an old umbrella will do quite well. THE SIEVE. This also may be bought of a satisfactory quality. My own is made from ordinary square mesh chicken wire with % inch mesh. The top is stout, unbleached muslin, about twice as deep as the diameter of the sieve, say 30 inches. The cloth to go with the sieve is a piece of any white material, about 40 inches each way, a little larger is not a disadvantage. THE INSECT NET. Very few Heteroptera are taken with the insect net ir flight. It is well to take such a net to get Acanthiidae (Saldidae) which are very wary and lively. But even so, the water net will meet this purpose at a pinch, or even the sweeping net will answer, particularly if the bugs are hiding among grasses.

The. species was captured in a rather densely wooded portion of the trail along Cameron Creek. It is intermediate in appearance between satisfacta and excelsaric. and ia genitalia approaches most closely to the latter species, both having the apex of the uncus broad and truncate with the lateral edges produced to fine points, and the gnathos obsolete; in this respect these two species differ from all the others figured in my studies in North American Cleorini, Pl. IV. At the time of writing this paper no males of evcelsaria were available for dissec- ticn but I now am enabled to figure the genitalia of a specimen from Victoria, B. C. (fig. 6) and also have a male before me from Keremeos, B. C. The genita- lia of umbraria differ in the shorter penis and the finer spining of the apical cut niccd area; the moth is less contrasted in coloration, has a less rigidly oblique t.p. line on primaries, and pronounced discal ringlets on both wings, which feat- ures should serve to separate it from excelsaria. Macaria incolorata Dyar syn. purcellate Taylor, 1908, Can. Ent., XL, 98. A series received from Mr. J. W. Cockle, including paratypes of both incolcrata Dyar and purcellata Taylor, would indicate that the first name was based on males, the second on females of a single species. In the entire group to which the species belongs it is usual for the females to show considerably better defined maculation than the males. Dr. Dyar’s name has priority and the species appears to be a valid one, possibly most closely related to seamaculata © Pack. frcm Labrador. The species listed as purcellata by Bowman from Nor- degg, Alta., is probably better placed under sexmaculata for the present until the group can be carefully revised; it occurs in larch swamps only and I have *—Contribution from the Division of Systematic Entomology, Entomological Branch, Dept. of Agric., Ottawa. | H { y t | _ THE CANADIAN ENTOMOLOGIST JAN., 1925. beaten larvae from larch trees which may belong to this species; unfortunately they were not bred through to the adult stage. CRAMBIDAE. Crambus paganellus sp. nov. Male. Belongs in the group with trichostomus, labradoriensis and oregon- icus and is closely related to the former. Primaries deep brown, shaded with white; a broad dark brown band crosses the median area of wing, rounded out- wardly below costa, expanded in central portion and sending a short projection towards base of wing, then inwardly oblique to inner margin before middle, shaded on both sides, especially in central portion of wing, with white; a narrow, white, subterminal line, gently rounded opposite cell and minutely dentate in low- er portion, with a slight inward angle above tornus; a faint white spot (sometimes lacking) at apex of wing and a row of seven black, terminal dots; fringes dully metallic. Secondaries deep smoky with paler fringes. Expanse 17 mm. Female. Similar to male but rather smaller and lighter in coloration.

The narrowness of the subterminal white line which is evenly rounded, not angled, opposite the cell, separates the species from trichostomus. The speci- mens were all captured in a tamarack swamp. EUCOSMINAE In working over the material in the Canadian National Collection of this Tortricid subfamily with the aid of Heinrich’s recent Monograph (Bull. U. S. N. M. 123), I have come across a number of species which I cannot place and which appear to be undescribed. I venture to offer the following descriptions of certain of the more striking species. Thiodia albertana n. sp. (Fig. 1) Male. Palpi purplish-gray, white inwardly. Primaries very pale ochreous, shaded along outer margin slightly with brown, this color forming small wedge- shaped patches between the veins. At base of wing is slight brown shading but not extended to form a median streak; a fine’ brown line runs through the outer half of cell and the cubital vein is outlined in brown in the basal haif of wing; veins 3 and 4 are narrowly brown, bordered above and below by silvery whitish; this color alone outlines the remaining veins beyond the cell, the inter- vening spaces being shaded somewhat with brown; before apex of wing on costa are two curved silver marks enclosing a few brown scales; fringes purplish- black in basal half, sprinkled with white scales, outer portion unicolorous smoky. Secondaries pale smoky; fringes similarly colored with a dark basal line. Expanse 22 mm. Holotype— 3, Lethbridge, Alta., June 14, (H. L. Seamans); No. gto in the Canadian National Collection, Ottawa. ; Paratype—1 ¢, same locality, June 23. Close to radiatana Wlshm. but as distinct from it both in maculation and genitalia as are the other members of the group. The general striate character of the maculation without any definite dark patches seems to be characteristic. LVII. THE CANADIAN ENTOMOLOGIST 13 Thiodia indeterminana n. sp. (Fig. 2) Male. Close to awemeana of which it may eventually prove to be a form. Primaries of a dull gray color with diffuse darker markings of either gray-brown or olive brown. The type of maculation is similar to that of awemeana but neither clean-cut as in this species nor of the same bright brown shade. The basal area is largely occupied by an obscure dark shade forming an outward angle about the middle of the cell; the dark postmedian band is also ob- scure and merges into the general ground color; the ocellus is outlined by silvery lines but contains no definite dark lines; on costa beyond cell are several silvery streaks more or less merging together interiorly; fringes in the basal half whitish, crossed by a dark line; outer portion unicolorous dark smoky. Secondaries rather pale smoky with similar fringes. Female. Smaller than the male with outer portion of primaries consider- ably suffused with ruddy-brown and frequently with better defined maculation. Secondaries deep brown with paler fringes.

Paratypes—i2 ¢, 10 9, same locality and collector, May 7, 20, 26, 27, 29, 31. The species falls, according to genitalia, in a group with awemeana and essexana. In these the genitalia are smaller in size and show less of a lateral outward bulge to the claspers than is found in the other allied species; this bulge can easily be observed by an examination of the organ in situ from the ventral side, by removingya few scales at the end of the abdomen. Due to the bulge an open, heart-shaped space is formed between the base and apex of the claspers ; in formosana, radiatana, etc., this space is very broad but is much narrowed in the awemeana group. Henrich’s figure of awemeana (PI. 13, fig. 76) does not seem to agree with my slides made from material both from Aweme, Man., and Ottawa, Ont., and I suspect a possible error of labelling. The genitalia of indeterminana and awemeana are very similar; there are a few minor points of distinction, the most noticeable being found in the socii which in awemeana are widely separated apically and rather sparsely haired ; in indefinitana they are more closely approached, running practically parallel to each other from base, and are also hairier. Indeterminana, like others of the group, appears to have an extended distribution as specimens before me from various localities in Alberta and British Columbia agree with our eastern specimens in maculation and genitalia. Thiodia modernana n. sp. (Fig. 4) Male. Palpi, head and thorax dark gray-brown, peppered with whitish scaling. Primaries rather dark gray with brown antemedian and postmedian bands; the basal area shows considerable of the ground color but is darker at extreme base and along costa; the antemedial brown band is rather broad, the inner edge strongly concave, the outer edge outwardly oblique to below cell, then angled slightly and concave to inner margin; the following palish band of ground color is narrow to below cell, broadening then abruptly and occupying on the inner margin about one-third the length of this margin; it is faintly 4 THE CANADIAN ENTOMOLOGIST Can.

THE CANADIAN ENTOMOLOGIST 15 strigulate with brown; post-median band even in width, outwardly oblique from about middle of costa to just before tornus, the inner edge slightly bent in above inner margin of wing, the outer margin evenly convex; on costa beyond this band are three geminate white dashes, close together, with a fourth one just before apex of wing; the inner of these geminate marks gives rise to a narrow metallic band which borders the postmedian dark band and forms the inner edge of the ocellar spot in the lower portion of wing; just beyond this in costal half of wing is anofher metallic Y-shaped band, formed by the junction of lines from the second and third costal dashes, and a narrower metallic band prolongs the apical dashes to just above a metallic line forming the outer edge of the ocellar area which is brown and crossed by three black dashes; above the ocellus the subterminal area between the above mentioned metallic streaks is brown, bulb- shaped, with the neck resting on the costa; fringes peppered with white in basal half, outer half dark gray with extreme tips whitish. Secondaries with veins 3 and 4 stalked, cark smoky, slightly paler basally; fringes smoky, paler outward- ly. ,Beneath pale smoky with the inner half of secondaries whitish. Expanse 18 mm.

According to Heinrich’s key this species runs to couplet 62 but I cannot trace it further and the genitalia do not agree with those of any of the species listed after this couplet; they seem closest to those of migratana Heinrich, judging by his figure, but the anal angle of the cucullus is sharper and the ex- cavation of the: neck less prominent. Two rather smaller specimens from Cranbrook and Salmon Arm, B.C., ate before me; as the genitalia of the specimen from Cranbrook show no appre- ciable difference from those of the eastern specimen, I presume that we are dealing with a slight western modification of modernana. Thiodia convergana n. sp. (Fig. 3) Male. Very similar to the preceding species but with noticeably paler gray areas at the base and middle of wing; the dark bands are rather narrower and between the fold and inner margin are much deeper in color, being shaded with a dark chocolate-brown; the antemedian band is frequently more or less obsolescent in costal portion; the postmedian band is generally reduced in width at the inner margin rather than broadened out as is the case in modernana; the black cross-bars of the ocellus are variable in number and may be reduced to mere black dots. Secondaries paler than in modernana, the basal area on the upper side and nearly the entire wing on the underside being whitish. _Expanse 16-19 mm. Holotype— 4, Aweme, Man., May 21 (N.

This may eventually prove to be merely a prairie race of modernana but certain differences in the genitalia, notably the generally larger size and the 16 THE CANADIAN ENTOMOLOGIST JAN., 1925. much broader socii lead me at the present time to describe it as a distinct species. Thiodia complicana n. sp. (Fig. 5) Male. Primaries pale grayish white with rather obscure gray-brown maculation; the entire basal area on dorsal half of wing is gray-brown, the outer edge of this area is directed obliquely outwardly to the cubital vein where it forms a sharp angle; a whitish shade along this vein cuts off the patch more or less from the costa which is also gray-brown with slight whitish spotting; a gray-brown postmedian band is present, better defined outwardly than inwardly, the outer edge strongly oblique from middle of costa to lower angle of cell, then almost perpendicular to inner margin; beyond this band on costa are. the four usual geminate white dashes, connected inwardly by a whitish suffusion which extends to apex of wing and cuts off four small gray-brown costal patches of which the middle two are largest; in this area the veins are somewhat mark- ed with gray-brown, giving a strigate appearance; a small dark gray patch on outer margin just below apex; outer margin more or less suffused with the same dark color; ocellus indistinct, whitish, with central dark gray shading; fringes white in basal half, dark smoky outwardly. Secondaries pale grayish white, tinged with smoky outwardly and with whitish fringes; veins 3 and 4 long- stalked. Expanse 16 mm. ‘ Holotype— 8, Osoyoos, B.C., May 19, (C. B. Garrett); No. 908 in the Canadian National Collection. The species would apparently run to tenuiana Wishm. by Heinrich’s key but the type of genitalia is that of the octopunctana gromp; it is closest in appearance to nepotinana Heinr. but the broadly white basal half of the fringes distinguishes it. The head is unfortunately missing in the type specimen. Thiodia youngi n. sp. (Fig. 6) Male. Palpi gray, peppered with white scaling; head and patagia white ; thorax whitish tinged with brown. Primaries white. with a bright brown basal area and similarly colored broad oblique median band; the outer margin of the basal area is outwardly oblique to below cell, where it forms an angle and descends almost perpendicularly to inner margin; the broad pale antemedian band is white on its costal half, slate-colored on inner half, due to an admixture of white and black scaling; the brown median band is outwardly oblique and of even width throughout ; its outer edge in costal half of wing is partially defined by a whitish metallic streak, more or less joined to a silvery lunate mark which defines the upper edge of the large ocellus; this ocellus is filled with an admix- ture of black and white scales, causing a slaty-gray appearance, and contains in its lower half three rows of black dots, four to a row, on a slightly ochreous background and with a central and two lateral vertical metallic bars; the white costal area beyond the median brown band shows three smoky brown costal dots and there is a narrow bright brown streak below apex along outer margin, defined inwardly by a silvery line; fringes similarly marked and colored to the ocellus with the outer edge plain whitish. Secondaries deep smoky with whitish fringes, slightly smoky at base. Expanse 19-22 mm. Holotype— é, Waterton Lakes, Alta., July 10, (C. H.

This handsome species was captured by Mr. Young near the bare summit of a peak about 7000 ft. high; it is evidently related to octopunctana Wlshm. Amongst the material collected by: the. Canadian Arctic Expedition and referred to under the generic heading Eucosma (1920, Rep. Can. Arct. Exp. Vol. III, I p.. 46) I have found, besides a number of specimens of Gypsonoma parryana Curtis, a hitherto unrecognized species, two specimens of a Thiodia species, apparently undescribed; neither of these is in good condition, but one side of the primaries on each is sufficiently perfect to give a fairly adequate idea of the type of maculation. “The species obviously belongs in the octopunctana group with basal patch widening obliquely from costa to inner margin and the genitalia are very close to those figured by Heinrich for this species (fig. 126) ; I describe it as follows :— Thiodia camdenana n. sp. Male. Thorax deep black-brown, partly scaled with light brown; primar- ies deep smoky brown, considerably suffused with whitish scaling (probably more so in perfect specimens than in those before me); the basal patch is bounded by an irregularly oblique line, extending from costa one fifth from base to about middle of inner margin; this patch is scaled with light brown over an underlying layer of black-brown. scaling ;. beyond it the wing is suffused more or less with whitish; based on the. costa, on the outer third of wing, is a large irregularly triangular area bounded by. rather broad bands: of light brown and strongly suffused with white scaling; the base of this triangle extends from about middle of costa to. shortly: before apex of wing and its apex is at a point near. lower angle of cell;. contained within this triangle are two dark cos- tal spots and a third one rests on its outer edge; along the outer margin of wing is slight brown scaling; secondaries light smoky with whitish fringes, veins 3 and 4 coincident.

Paratype—t 4, same locality, end of June, 1914, (T°. Johansen). Thiodia rupestrana n. sp. (Fig. 7) Male. Very similar to Walsingham’s figure of transversa (Trans. Ent. Soe. Lond., 1895, Pl. XII, fig: 16); 1 would have determined it as this species if it were not for the fact that the genitalia agree with Heinrich’s figure of those of elongana rather than of transversa. Compared with Walsingham’s figure the dark areas of the present species are sepia brown rather than olive brown; the pala median banding is-less, distinct and more suffused with brown sprinkling and above the inner margin shows a distinct outward bulge, causing a corresponding narrowing of the dark postmedian band; this latter band does not show such a sharp outer angle as in fransversa but at this point is connected more or less distinctly with an oval brown spot situated above the ocellus and defined outwardly by a silvery (sometime obsolescent) curved line; there are two dark costal spots and generally a trace of a third, the spots increasing in size towards apex of wing; below apex on outer margin a white line cuts off a small oval brown spot. cia Female. ‘The single specimen before me shows considerable light brown suffusion over the basal dark area which also contains a short white basal 18 THE CANADIAN ENTOMOLOGIST JAN., 1925. dash (probably also present in well-marked males).

Paratypes—2 8, same data; 1 ¢, Calgary, Alta., (Wolley-Dod);1 ¢, Laggan, Alta., (T. Bean). Although agreeing in type of genitalia with elongana Wlshm. I hardly like to associate rupestrana as a mere form of this species. My specimens were cap- tured on the bare slopes of a mountain (about 5,500 ft.) in quite fresh condition in the latter part of June whereas Walsingham’s species was taken two months earlier in Northern Oregon, probably at a quite low level along the John Day river. Heinrich records elongana from Kaslo, B.C., and I have a specimen from this locality (June 21, 1902) before me from the Cockle collection which cer- tainly looks distinct from rupestrana. I am not quite satisfied that this is the true elongana but it evidently is what Heinrich has determined as this species and I follow his identification until the type can be studied. In my entire type series veins 3 and 4 of secondaries are united. Heinrich has apparently confused two closely allied species under the name Eucosma serpentana Wishm. He notes and figures (figs. 206, 207) dif- ferences of genitalia between Pullman, Washington, and Mesilla, New Mexico, specimens but is inclined to consider these differences as no more than racial. Incidentally it might be well also to note that Pullman, Washington, does not belong in the Pacific Coast region, as stated by Heinrich; the town is located in the extreme south east of Washington State, far east of the Cascade range, and the region is typically semi-arid. From Alberta and especially from the southern portion of the province (Lethbridge), I have series of specimens which I first separated into two groups on superficial characters; one of these groups undoubtedly represents serpentana Wlshm., the figure given with the original description being unmistakable and the genitalia agreeing with Heinrich’s figure 207. The genitalia of the second group, the specimens of which show marked variability in maculation, agree with Heinrich’s figure 206; several slides made from each series show no variability from the individual type and as further a specimen from Pullman, Washington, kindly submitted to me by Mr. Heinrich for examination, proves on maculation to fall into my second group, I believe I am justified in considering that two species are represented. For the unnamed one I propose the following name: Eucosma ophionana n. sp. Very close to serpentana Wlshm. but with less elongate primaries; ground color a slightly darker fawn-brown than is usual in serpentana, this color showing a marked tendency to become diffused over the entire wing and obliterate tlie white markings; these white markings are essentially the same as in serpentana but the white basal streak, which is separated in serpentana from the patch on middle of inner margin, is in the present species broadly joined to this patch; the white costal streaks are less confluent with each other internally in ophion- ana and the inner one ‘shows a tendency to unite with the apex of the waved streak above tornus. The genitalia are represented by Heinrich’s fig. 206; the cucullus is more elongate in shape than in serpentana and the uncus is broadly LVII.

The type is a particularly clearly marked specimen; some of the Lethbridge paratypes are much suffused with brown and in one the white maculation has almost disappeared; no difference in genitalia can be noted, however, between these specimens.. Eucosma heinrichi n. sp. (Fig. 1) Male. Palpi smoky fawn laterally, whitish above and below; thorax pale whitish fawn, primaries whitish, sprinkled with pale fawn; the costal fold is smoky fawn, and below the apex of same, in the median area, is an obscure fawn-brown spot representing the basal patch; at the end of cell is another similarly colored spot, connected with the outer margin by a dull leaden shade; on costa before middle are three minute brown dashes and beyond middle three . larger equidistant triangular spots, alternating with three minute dashes; all of these give rise to oblique fawn-colored, rather obscure lines which terminate in the above mentioned leaden shade; the apex of wing contains a triangular fawn- colored spot which is continued by a line along outer margin almost to tornus; the ocellus is formed by two semiparallel creamy-white shining bands between which are traces of two or three short black dashes; inner margin spotted with fawn- color; basal half of fringes white, heavily sprinkled with fawn, outer half rather dull pale fawn, deepest near apex of wing. Secondaries whitish, shaded broadly with very pale smoky in outer half; fringes white with dark basal line. Expanse 20 mm. Holotype— é, Aweme, Man., Aug. 10, (N.

Heinrich, who has seen the specimen, states that “the genitalia are most like those of fuscosparsa Wlishm.; but the pattern resembles totana Kft. with white areas of forewing more ashy, termen less slanting and costa more arched. It would follow totana in my arrangement.” Eucosma vagana n. sp. (Fig. 2). Male. Palpi and thorax light brown, the third joint of the former tipped with blackish; primaries light ruddy brown, paling in the costal and apical por- tion of wings, due to the presence of numerous whitish gray, shining striae; costal fold fawn-brown; beyond the fold an alternating series of brown and whitish gray oblique striae; there are 8-10 brown striae, tending to coalesce in pairs shortly below costa; the inner striae reach to the cell, the outer ones to the outer margin, the whole apical area of wing having, on this account, a de- cided strigulate appearance; ocellus indicated by a broad, roughly U-shaped, shining, whitish band, enclosing several poorly defined blackish streaks; basal half of fringes white, heavily sprinkled with brown, outer portion pale leaden. Secondaries whitish slightly tinged with smoky. Expanse 18 mm. Holotype— é, Aweme, Man., June 27, (N. Criddle); No. 1208 in-the 20 THE CANADIAN ENTOMOLOGIST JAN., 1925. Can. Ent. Vor. LVIL. PLATE 2. NEW CANADIAN LEPIDOPTERA LVII. THE CANADIAN ENTOMOLOGIST Canadian National Collection, Ottawa. Of this species Mr. Heinrich states, “Like and next to mandana Kft. but paler on underside, with paler hind wing and lacking the faint basal patch on forewing. The neck of the harpe is shorter than in mandana. The genitalia are more like those of comatulana Zell. but your specimen is much darker.” I am unacquainted with mandana but from a series of comatulana before me from Aweme, Man., the present species can be distinguished by its deeper color and lack of any blackish spots in and beyond the cell. Eucosma simplex n. sp. (Fig. 3). Male. Palpi rather smoothly scaled, smoky brown outwardly, pale ochre- ous inwardly; head and thorax deep smoky brown, the patagia sprinkled with minute white dots. Primaries smoky brown, somewhat striate in appearance, due to the fact that the veins in and beyond the cell are marked in pale ochreous. Under a lens the whole wing can be seen to be sprinkled with minute whitish dots but no other maculation is apparent; fringes concolorous. Secondaries smoky, paling into whitish towards base in the male. Expanse 23 mm. Holotype— é, Calgary, Alta., Apr. 30, (F. H. Wolley-Dod); No. 1209 in the Canadian National Collection, Ottawa.

The species is best placed near landana Kft. which differs structurally in the much longer ciliations of the male antennae, these being so long as to almost cause the antenna to appear shortly bipectinate. Epiblema benignata n. sp. (Fig. 8). Male. Pelpi and head brown, at titnes with a slight rufous tinge. Prim- aries brown with a large subquadrate white patch on dorsal margin, not quite at- taining costa and a white ocellar spot. The basal area is deep brown, its outer edge sharply defined and slightly inwardly oblique from costa before middle to dorsal margin at inner third; the large median white area contains a few scat- tered brown spots, it is narrowed slightly towards costa and its cuter edge is irregular; the following dark area is tinged with deep ‘slate-color and contains two or three black dots placed in a vertical row near inner margin of the ocellus ; there is a series of bright brown oblique streaks interspersed with white 6n outer half of costa andthe apical half of outer margin is similarly bright brown; the wh'te ocelltis frequently contains several black dots in its upper ‘half. deep smoky flecked with white.

The male genitalia resemble more closely Heinrich’s figure of those of claypoleana than of ratzeburgiana. Epinotia sagittana n. sp. (Fig. 10). Male. Palpi, head and thorax light brewn. Primaries with brown basal area, oblique median band and oblong spot from below apex nearly to anal angle; the remainder of the wing is dull grayish, due to a sprinkling of white scaling on a purplish background, and contains a slight admixture of dark scales, especially along inner margin; the basal brown area is defined outwardly by a black-brown line, edged with pale yellowish and elbowed below cell; there 1s a similar dark line parallel to the outer one, close to base of wing and the area be- tween these two lines shows traces of whitish scaling; the antemedian pale band is twice as broad on inner margin as on costa; the dark median band broadens centrally, forming a slight outward projection below cell; at inner margin it is considerably narrowed; between median band and apex of wing there are four dark spots on costa, the outer two of which are connected at their bases by the subapical dark patch, this patch, as well as the median band, is partially out- lined by a black-brown scaling; fringes dusky, sprinkled with whitish. Second- aries pale smoky, slightly irrorate with darker lines; on the underside still paler with the dark lines more distinct. Expanse 21 mm. Holotype—é, Departure Bay Biol. Station, B. C., Aug. 25, 1908, (C. H. Young) ; No. 918 in the Canadian National Collection, Ottawa. By Heinrich’s key the species would run to,caption 34 in Section A, as it possesses a costal fold and the outer margin is slanting. I can however trace it no further and the genitalia with the barb-shaped uncus seems quite distinct from anything figured in the “Monograph.” In his monograph (p. 210), under Epinotia solicitana Wik. Heinrich mentioned two specimens reared from hazel catkins at Falls Church, Va., which differed from typical solicitana in male genitalia. I have a small series before me corresponding with these hazel specimens (which Mr. Heinrich has been kind enough to loan me) in genitalia and coloration. As the genitalic differences are sufficiently distinct to warrant the supposition that we are dealing with two species I describe the hazel feeder as follows: Epinotia corylana n. sp. (Fig. 4). Primaries scarcely distinguishable from those of solicitana in maculation ; ground color a rather paler brown than that, of the typical Nova Scotian form with considerable white shading along basal portion of costa and traces of a pale LVIL.

The dark median band is thickest in its costal half whereas in solicitana it is quite narrow in this region and frequent- ly broken, thickening however noticeable above anal angle. In the male geni- talia the spine cluster on the sacculus is directly on the lower margin which makes a rather sharp angle at this point; in solicitana the spine cluster is in the central portion of sacculus, the uncus is broader and the socii are longer.

Fore wing distinctly longitudinally bicolored, the costal area be- ing deep brown, the inner area pale creamy ochreous; this latter area is narrow at the base, broadens rapidly beyond inner third of wing and is of more or less even width to subterminal area with a slight rounded indentation of the dark color about centre of wing; from subterminal area it runs obliquely to apex ot wing leaving the whole terminal margin paler; inner margin dotted with brown and traces of a dark broken terminal line; fringes slightly darker than pale area of wing.

M. ; In the allotype and paratypes the pale areas are lightly sprinkled with brown dots and the costal edge is slightly variegated with pale ochreous; such differences, I imagine, are merely individual but, the variant specimen being the only male from which a slide of genitalia could be made, I have designated this the holotype to avoid confusion. The species seems to belong in the lindana group but is abundantly distinct on genitalia which approach closest to Heinrich’s figure of lomonana (fig. 333) with still further reduced uncus. The specimens were secured from Mr. Cockle’s collection and the ¢. paratype was identified provisionally by Dr. Dyar as Epinotia biangulana Wlshm. (Lepid. Kootenai District, p. 928), which now proves to be a totally different species. Under No. 9 of Plate I. I figure the genitalia of Epinotia plumbolineana Kft. I had at first intended to describe this as a race of medioplagata Wlshm, but found later that Kearfott’s name was applicable. I cannot agree with Heinrich in placing it as a race of cruciana; in genitalia it is similar to medioplagata but the maculation shows differences sufficient to warrant the supposition that it is a good species.

THREE NEW DIPTERA FROM LABRADOR BY C. HOWARD CURRAN, Ottawa, Ont. A small collection of Diptera from Labrador, collected by Mr. F. W. Waugh, contained the species described below. ‘The Chionea is particularly in- teresting, having been collected on snow in mid-winter, most of our records being earlier in the season or in the spring. TIPULIDAE Chionea waughi n. sp. Brownish red, the eyes brown, legs reddish, the tarsi brownish except basally, posterior femora as long as the abdomen, incrassate. Length, 6 to 6.5 mm.; width of thorax 1 mm. Male. Head dull brown, in certain lights with silvery grey pollen; the pile fuscous; antennae and palpi brown, the former with seven segments, the flagellum slender, composed of four segments in addition to the basal short conical one, the apical four longer than the first antennal segment which is as stout as the second; the second constricted on more than the basal half. Proboscis brown, its inner side white. Thorax and abdomen with greyish pollen in some lights, the abdominal tergites becoming paler apically, the sternites densely grey pollinose, the mem- brane pale yellow. Halteres “Indian-club” shaped, yellow. Genitalia large, fer- ruginous or brownish red, the apex of the large basal portion without emargina- tion or projections; the median upper fleshy piece white, the claspers simple, strong, and elongate, curved inwardly on apical half. Female. Length 5-5 mm. Width of thorax .75 mm. Differs in having the abdomen reddish biown. The chitinized portion of the genitalia is pale yellowish, the sheaths of the ovipositor strongly curved upwards; a small triangular pro- jection just apicad of the wise of the L le color; the lower stout portion tapers to a point. : Holotype— 4, Voisey’s Bay, Labrador, December 5th, 1921, (F.° W Waugh) ; No. 706 in the Canadian Natiénal Collection, Ottawa. Allotype— ?, Cabot Lake; Labrador, September-October, t921 (W “— h) Paratypes—2 4 4, same data as Holotype. The males were found crawling about on spow. No information acconf panies the female. This species is most closely allied to C. valga but is readily disting:tished by the absence ‘of'a wide projection on the upper margin of the basal portion of the genitalia and the long antennal flagellum. | EMPIDIDAE Iteaphilsa, curva n. sp. Palpi two-thirds as long as proboscis; antennae elongate, slender: upper lamellae elongate triangular, a slender process’ rises from the apical internal base of the lamellae and is almost as long; oedagus with the basal section gradually widening to the apex, the apical part composed of a narrow dorsal arm and a stouter ventral one each almost as long as the basal section.

Antennae a little longer than the proboscis, slender, the first two joints black haired, the third twice as long as the first two, slightly tapering ; the style stout, shorter than the second antennal joint, parallel sided, its end acute. Mesonotum with three wide golden brown pollinose vittae, the pollen else- where much thinner; black pilose, the hair long. Pleura and coxae with grey- ish yellow pollen and black pile. Scutellum with long black pile. Legs black or brown, the knees reddish, the pile black, long behind the front four femora, ciliate on the antero-ventral and dorsal surface of the hind ones, and forming single row of dorsal cilia on the hind tibiae. Tarsi simple. Wings strongly tinged with brown, the stigma long, brown; venation as in macquartii. Halteres brown, the knob pale brown. Squamae white, with brown- ish fringe. Abdomen brownish yellow pollinose in some lights; the pile long, black, but almost wanting on the disk. Lower lamellae of genitalia subtriangular, slightly curved upwards apically, shining brown, with black hair. Holotype— é, Nain, Labrador, June 15, 1922, (F. W. Waugh) ; No. 708 in the Canadian National Collection, Ottawa. This species differs from J. macquartii in its larger size, longer antennae and style, slightly double-curved fork of the third vein, anal appendages, and coarctate palpi, these being slender at the base and broadly constricted on the apical third. SCATOPHAGIDAE Eugenacephala Johnson This interesting genus was erected by Mr. C. W. Johnson, (Occ. Pap. Bost. Soc. Nat. Hist., V, 22, 1922) for a species inhabiting the salt marsh region of the New England States. A specimen before me from Labrador agrees perfectly with the generic description but is quite distinct from the genotype, E. salsa. It is rather difficult to place the genus as it appears to offer no characters in common with any genera known to me, although it appears, as pointed out by Mr. Johnson, to be best placed in the Scatophagidae. Mr. Johnson states that there is a bristle on the hypopleura and none on the sternopleura. This bristle is located near the posterior edge but distinctly on the sternopleura in my specimen. Eugenacephala ruficeps n. sp. Length, 6 mm. Male. Cheeks and lateral margins of the face leathery reddish, the face and front brownish reddish, the former similar in color on the lower half of the cheeks, the large oval antennal grooves rather yellow, dull; the whole sub-shining, the front thinly greyish pollinose; occiput and vertex dull black, this color reaching broadly forward to and covering the ocellar triangle, and also narrowly encroaching upon the front at the orbits, the region about the neck, reddish, the whole coarsely, thinly greyish pollinose, and with short 26 THE CANADIAN ENTOMOLOGIST JAN., 1925. black hairs.

It is gratifying to announce that the compilation of the proposed List of the Insects of New York State is now definitely to be completed. Dr. M. D. Leonard, who was appointed Editor-in-Chief while Acting State Entomologist of New York, returned to the Department of Entomology at Cornell University, Ithaca, New York, December last to again take charge of the project. His entire time will be devoted to the completion of this list and the New York State College of Agriculture has definitely promised ee provided the MS is ready by June 1, 1925. It is estimated that over 16,000 species, will be listed as definitely occur- ring in New York, together with as complete distribution data within the State as is known for each species. Several orders are already practically completed. Over one hundred of the leading specialists are actively. co-operating. The Editor of the List will greatly appreciate definite New York State records. in all groups and will see that full credit is given to every co-operator.
