We are indebted to the Toronto Engraving Company, Limited, for the beautiful plate given in this month's issue. The invention of the trichromatic photographic process of illustration is undoubtedly one of the most important stimuli to scientific work of recent years. Especially is this the case in the study of insects, where it is frequently necessary to depict accurately very slight differences, both in form and colour, which could be described only with difficulty, or at greath length.

Among a large series of Coleoptera collected by Mr. C.H. T. Townsend in the northwestern part of Mexico and forwarded to some years ago, I not an interesting new Carabus, which may be described as follows:-

Carabus Townsendi, n. sp.—Somewhat similar to Forreri, Bates— Ann. & Mag., N. Hist, ser. 5 IX, p.320— from Durango, but narrower in form, the elytra having similarly close-set unimpressed series of very minute punctures but having each only two sereis of larger, widely-spaced, impressed foveæ, the inner of the three series of Forreri being wholly absolete, the middle series only present in basal half and the outer extending only to apical fourth, the lateral margin more narrowly reflexed and with bluish reflection. Length, 21 mm.; width, 9 mm.

A number of interesting undescribed species of Coleoptera have accumulated in my cabinet, principally as the result of my own trips to the western parts of the country. The description of several of these follow, care having been taken to avoid describing forms belonging to genera of great extent which have not been recently monographed:

Iulidæ are not insects, and my only hope of getting this note on record is in that their work in the corn-fields of the Middle West may be easily confused with that of several very different species of insects.

309. M. Dodii, Smith.—(Can. Ent., XXXVU., 152, June, 1904). Described from Calgary and from Bullion Park, Colo. The type is a Calgary specimen at Rutger's College, and I have two ♂ co-types.

In collection insects of Poquonock, Conn., July 18, 1904, my assistant, Mr. B.H. Walden, found coccinellid larvæ feeding upon a species of Aleyrodes which is probably undescribed, and fairly common there upon the leaves of hazel, Corylus Americanus. These larvæ were brought to the laboratory, and were fed upon Aleyrodes vaporuriorum, Westw., which they ate greedily.

Several entomologists have discussed with me the question of the distinguishing characters of Ranatra quadridentata, Stal, and Ranatra fusca, Pal. Beauv., and in consequence I venture to set forth here briefly and plainly the differences between these two and Ranatra kirkaldyi, n. sp, which I took for the first time in New York State.

This species, described by Mr. A. Busck, in the Proceedings of the United States National Museum, XXXVII., P. 746, 1904, paper No. 1375, is Sciaphila trigonana, Walsingham. [Lepidoptera-Heterocera British Museum, Part IV., p. 22, 1879; Dyar's Catalogue, No. 5413; Smith's List, 1903, 5831.] The species is well figured by Walsingham, Plate LXV., fig. 7.—

Nomada Granicheri, n. sp.—♀. Length, about 10½ mm.; black, with bright lemon-yellow markings, the only red is on base fo antennæ, legs, and a little on mandibles; mandibles simple; anterior coxæ without spines; basal nervure meeting transverso-medial; third antennal joint slightly longer than fourth. This is a Xanthidium with the face black in the middle and with yellow lateral marks, like teh European N. succincta.

The spring here was an unusually cold and late one, and it was not until April 17th that I saw a moth of any description, and that “first swallow” was only a Depressaria Canadensis, Busck. I did not see a single specimen of Leucobrephos Middendorfi, Men., though an April seldom goes by without my doing so, and generally at some awkward moment when no net is handy. Year before last I was repotting some plants on the sunny side of my house, when a Leucobrephos flew against me, dropped at my feet, and was off again before I could pot it.

Fore wings white, with small orange patch at apex, marked with black dots and bars as follows: Six spots on costa, about equidistant, the basal one slightly removed from costa and the second smaller than the others, a round spot in cell, followed by four short parallel transverse bars beyond it, lying close together, the third one joining spot on costa. A short longitudinal dash on inner margin at base, followed by five transverse bars from median vein to inner margin, the first, however, not quite reaching it. Of these the third and fifth are narrower than the others and in the male especially tend to become broken, probably in some specimens they would be almost or quite wanting.
