The following list has been prepared from collections made in the Nortwest Territories of Canada during the seasons of 1879, 1880 and 1881, by Prof. John Macoun, Botanist of the Geological Survey Department of Canada.

During the summer of 1879 collecting was done, starting from Fort Ellice, thence to the head of Long Lake; thence to the elbow of the South Saskatchewan; then after crossing the river, in an almost straight line to Battleford; then south to the Hand Hills, and still south to Blackfoot crossing; thence west to Calgary, and up the Bow River to the gap in the Rocky Mountains.

Paranomia Venablesii, sp. nov.— ♀. Length 10.5 mm. Black; abdominal segments 1–4 at apex with bands of a golden-yellowish pubescence; the head in front, the cheeks, the occiput, the thorax in front at the sides, the postsctellum the legs, and the abdomen beneath, all clothed with a pale or whitish pubescence. Wings hyaline, fuliginous at apex, the costæ and parastigma black, the stigmal and internal veins testaceous. Legs mostly black, the stigmal and internal veins testaceous. Legs mostly black, with tarsal joints 2–5 mostly yellowish. The head is rather finely, sparsely punctate, the thorax more closely and densely punctate, but with the punctures finer on the scutellum, while the metathorax in shagreened, opaque. The abdomen has the first segment minutely punctulate, the following segments being more or less alutaceous.

In a collection of Diptera, taken in Arizona by J. Thomas Lloyd, of Cincinnati, Ohio, during the summer of 1902, I find some species of sufficient importance to warrant recording notes concerning them at this time.

Chrysops proclivis, O.S.—Specimens of this species were taken in Oak Creek Canyon, July 5th. I have not seen a record of the species from this territory heretofore.

Our knowledge of the group Aphididæ in California has been limited in the past to certain forms that were of economic importance in their relations to cultivated crops. No systematic list of these interesting insects has heretofore been attempted in this region, and this has not been due to any lack of material, for the varying conditions of climate here seem to be particularly favorable to them.

Culex cantator, new species.—Female. Near sylvestris, but the seventh abdominal segment almost wholly yellow scaled, etc. Head black, oral margin and base of antennæ yellow, remainder of antennæ and the proboscis black, palpi brown, its scales chiefly concolorous, no cluster of white hairs or scales at their apices; narrow scales of middle of occiput golden yellow, the upright ones chiefly black, sides of occiput covered with depressed whitish scales and with a small cluster of black ones; thorax reddish brown, scales of mesonotum golden yellow, becoming pale yellow in front of the scutellum and on teh pleura; abdomen black, its scales black, except a crossband of yellowish white ones at base of each segment, the bands considerably narrowed at the middle, similar scales scattered over the sixth and nearly the whole of the seventh segment and alng apices of the two preceding segments; legs yellow basally, becoming brown on the tibiæ and tarsi, scales of femora chiefly pale yellow, of the tibiæ mostly black, those on the hind side pale yellow, on the bases of the tarsal joints whitish, those on the second joint of the hind tarsi covering about one-fourth the length of the joint, front tarsal claws toothed; wings hyaline, lateral scales of the veins long and narrow, hind crossvein nearly its length from the small crossvein, petiole of first submarginal cell from one-half to four-fifths as long as the cell; length, 4 mm. One specimen bred May 6, by, Mr. LaRaue Holmes.

Page 99. Apatela. As might have been expected from the inconspicous markings and uniform gray colour of the moths, the identifications of species of Acronycta, described by Walker and Guenée, have proved difficult and often contradictory. I am now inclined to waive all objections and accept Dr. Dyar's list as it stands. The only point I make is, the difficulty I have in believing that, having identified xyliniformis, Guen., already and orginally for Riley, I should have described specimens at a later period as pallidicoma; it seems to me yet possible that two forms are here “mixed up,” although I know xyliniformis to be inconstant.

Œcanthus Forbesi, n. sp. — ♂. General colour pale yellow. Length to tip of wings 17 mm.; greatest widht across closed wing-covers, 3.5 mm. Very slender, elongate in general shape, somewhat resembling Zabea bipunctata (DeG.), but the outline of the closed wing-covers is more elongate.

In the Canadian Entomologist for August, Mr. Theobald described a Cullex Kelloggii as new; the description agrees well with the specimens on which I founded Culex tarsalis*, and undoubtely refers to the same species.

My specimens were from the same lot as the one which Dr. Williston described as Culex, n. sp. †, to which description Lieut. Giles applied the name of Culex Willistoni, n. sp.‡ the latter name is therefore also synonym of tarsalis.

Euthrips tritici (Fitch.).— At Las Vegas, Hot Springs, N.M., on May 17, 1903, I found Ribes cereum, Doughl, presenting numerous flowergalls of rather pumpkin-like form and greenish-white colour, about 9 mm long and 8 broad. These consisted of the swollen and deformed flowers, the walls of the calyx being thickened and greatly inflated. I rather expected to find in them dipterous larvæ, but they contained nothing but thrips, which, I am sure, is responsible for the damage. After careful comparison with the published accounts, and especially that of Mr. W. E. Hinds, I am quite unable to separate the thrips from the well-known Euthrips tritici.

A number of new species. either entirely new or known only from Mexico or Central America, have been brought back by me from the lower Rio Grande. The description of these new species, together with a list of the species known to occur in that region, will be published by me in the Bulletin of the Museum of the Brooklyn Inst. of Arts and Sciences. The two following species are here described in advance, in order that they may be included in the revision of the Ptinidæ on which Prof. Fall is at work.

In the August number of this journal, Mr. Coquillett has given his reasons for not accepting Culex inornatus as the proper name for the species which he has called C. consobrinus. He bases his claim for the name consobrinus on a supposed error of Desvoidy's in the indentification of pipiens, relying on the length mentioned, 3 lines, as proof that Desviody's species could not have been the real pipiens. My own article on the subject, in the July number, had intimated that Desvoidy had erred in the measurment given. Since then I find that Theobald (Mon. Culicidæ. II.; 135) gives 6 mm. as the maximum length of pipiens; this, of course, is equivalent to Desvoidy's 3 lines.
