Lecanium (Eulecanium) caryarum, n. sp.—♀. Scale (after producing young) somewhat variable in form, from long. 6, lat. 3½, alt. 2⅔ mm., to long. 5½, lat. 4⅓ alt. 3¼ mm., the more swollen individuals probably affected by parasites; outline in transverse section nearly hemispherical, in longitudinal section more or less low-pyramidal, with the posterior slope considerably the shortest, the apex of the pyramid marked by a more or less prominent boss, sometimes inclined to be double. Colour of scale dark chestnut; sides pitted and plicate to a variable degree.

In the Canadian Entomologist, Vol XXVII. page 33 (1895), Professor T. D. A. Cockerell stated that Dr. James Fletcher and just sent him a species of Chionaspis from Charlottetown, Prince Elward Island — very abundant on the bark of Betula papyrifera – and that in comparing it with Prof. Costomck's description of C. Lintneri he believed it to be that species. Following the description of the Prince Edward Island specimens, Prof. Cockerell drew attention to a few probable points of difference between it and Prof. Comstock's description, but as he could find no positive differences he did not separate the form on Betula, inferring that the discrepancy was due either to variation in his specimens or the incompleteness of Prof. Comstock's description. I have since received specimens of the form on Betula papyrifera from Prof. Comstock and Dr. J. A. Lintner, and latter gentleman has also lent me Prof. Comstock's co-types of C. Lintneri. On comparing the two I was at aonce convinced that they were distinct, and upon giving Prof. Cockerell my reasons for thinking that the two insects could not be identical, he advised me to separate the form on Betula.

During his visit in 1896 to Robben Island, a low rock only 2,000 feet long, situated near the eastern coast of Sakhalin Island, in Okhotsk Sea, Dr. Leonhard Stejneger collected only two species of insects, both Coleoptera. One of them is a species of Bembidium, possibly new, but it should be compared with the numerous species from the mainland, which cannot be done at present. The other species belongs to the highly interesting genus Aegialites, and is described below as a new species. Aegialites Stejnegeri, Linell new species.

Wishing to obtain a series of males of our common ground wasps, I paid a visit on the afternoon of October 21st to a larqe nest of Vespa occidentalis, Cresson, that I had noted some time previously, near my house. The day was dull and the wasps sluggish, but quite a number of males and perfect females were crawling about the entrance to the nest. Among the wasps were some specimens of a conspicuous yellow and black Hymenopteron unlike anything that I had seen before. I secured nine specimens, all males, and on my return home easily made out by the help of Cresson's Synopsis that the insects belonged to the genus Trigonalys. The next step was to turn to Harrington's paper in the Can. Ent., XXVIII., page 108, and compare my specimens with the description of the unique Trigonalys canadensis. unfortunately, all my specimens were males, while Harrington's type was a female. Consequently the description did not quite fit, but on the following day I took three females and satisfied myself that the species I had found was the genuine T. canadensis.

At Brandon, Manitoba, in 1896, some very successful collecting was done on the prairies and open hillsides surrounding the town. Except in the valley of the Assiniboine River, which is still well wooded, the country around Brandon is very open–regular prairie country-with, of course, a good proportion under cultivation, it being one of the good wheat-growing districts of Manitoba.

Chlorotettix unicolor, Fitch.—An examination of the Fitch type in the National Museum shows this to be the form described by Mr. Van Duzee as galbanata. As this will leave Mr. Van Duzee's unicolor without a name, it may be known as Vanduzei. Vanduzei differs from all the other described species in a character not before noted—the ocelli are distant from the eyes,—while in all others they are about as near as their own width or nearer. Differing thus widely from other species referred here, Vanduzei must still remain the type of the genus, which should perhaps be used for it alone. The male of unicolor, Fh.. closely resembles in genital characters that of spatulatus which I have from Kansas and Texas.

Adult ♀.—Length, 5 mm.; width, 3 mm.; many are smaller than this, but this seems to be the average size of the adult containing eggs. Colour yellowish-gray, although they appear light gray, from the mealy secretion which covers the body.

Shape, ellipsoidal, dorsal surface quite convex, ventral surface flat, extremities rather pointed. segmentation quite distinct to naked eye. Extremely short lateral appendages, little projections just visible; caudal appendages a little longer.

Fifty-nine eggs of this species were found on a twig of Amelanchier Canadensis, at the “Gomin”, June 1st 1897. They were laid in four rows-—each row was about three-fourths of an inch long.

Melanoplus abortivus, new species.—Size rather small, especially the male. Female nearly as large as M. femur-rubrum, but proportionately much stouter.

Frontal costa nearly reaching the clypeus, subequal, though sometimes a little contracted toward the vertex, plane except a slight depression at the ocellus, or in the male generally slightly sulcate from just above the ocellus, rather thinly punctate. Vertex witht the margins slightly elevated, gently expanding in front of the eyes for a distance about equal to or somewhat less than that between the eyes in the female, rather greater in the male.

Brachynemurus niger, new species.

Female.—Length, 29 mm.; expanse of wings, 56mm.; greatest width of anterior wing, 7 mm.; length of antenna, 4 mm. Black, marked on head and thorax with luteous; sparsely hairy, more distinctly so on prothorax and abdomen.

Face scarcely convex, luteous, a transverse, shining black band above which extends upward so as to cover the inter-antennal area; this band is notched below, a black line extending form the notch almost to the clypeus; on either side between face, clypeus and inner orbit of the eye, a triangular black dot. Circumocular area mostly luteous, except along vertex, where it is piceous. Clypeus luteous, on each side anteriorly an impressed dot. Labrum transverse, rounded laterally, emarginate in front, luteous, darker on emargination where it is sparsely clothed with black hairs. Mandibles piceous, black at tips.

Larva.—Cylindrical, green, smooth, the setæ very fine and in-conspicuous, single, normal for the Noctuidæ.

Dactylopius Quaintancii, n. sp.

Adult ♀ Length, 2 mm. Width, 1.5 mm. Shape, ellipsoidal, much flattened. Colour, dark grayish-brown, the body is so covered with white secretion that its true colour only shows on the ventral surface, the colour of the dorsum appearing quite white. The white secretion mealy, projecting slightly on the lateral margins, but not forming well-marked filaments; posteriorly it is produced into two very short, but well-defined, caudal filaments; on the dorsum it is slightly raised into a longitudinal ridge.

Diastictis benigna, n. sp.

Expands 23 mm. Palpi rather long, heavy, drooping, blue-gray; front, thorax and abdomen blue-gray, the latter whitish lined posteriorly on segments. Fore wings bluish-gray, lightest on middle field, mixed with some black scales; basal line faint or obsolete, marked by a black spot on costa; middle line beginning with black spot at costa, then through black lengthened discal spot, then obsolete; outer line with black spot at costa, otherwise obsolete; outer field darker towards margin, with a large brown submarginal shading between 3 and 5. Hind wings even, smooth, blue-gray. Beneath dark bluidh fuscous on all wings, becoming blackish along outer margins; costa of fore wings speckled with black and gray.

Eutolype grandis, n. sp.

Ground colour an even, smooth, bluish-gray, washed with smoky brown. Head with a little admixture of brownish in front. Collar with a small central brown spot. Patagiac margined with brown. Basal tuft of thorax with an admixture of black scales. Primaries with all the ordinary markings obscured, the most evident Feature being a broad light gray band at inner third outwardly margined by a brownish shade, which is the darkest part of the wing. The basal space is uniformly smoky gray to the t. a. line, which is narrow, geminate, even,a little incurved between the subcostal and submedian veins. The included space is light gray, and light gray shade extends to the rigid median shade, including the orbicular. T. p. line narrow, geminate, denticulate, widely bent over the cell, then with a deep incurve beneath, narrowing the median shade at the inner margin. The entire median space beyond the gray band has a warm brown tint in which the large reniform is obscurely visible as a dull, lead-coloured blotch, outlined by paler gray scales. Beyond the t. p. line the wing is of the same dull gray as at base, interrupted by the diffuse, somewhat irregular s. t. line. There is a dusky line at the base of the fringes, which are alternately black and white marked at their tips. Secondaries smoky brown, much paler at base, and with a darker line at the base of the fringes. Beneath, primaries smoky blackish, powdered with bluish-gray scales in the terminal space, secondaries grayish-white, powdery, with a blackish outer line and discal spot.
