The smallest N. Am. red-winged species known. It has a resemblance to polygama and fratercula in the ornamentation of the primaries. Fore wings gray, shaded with blackish; lines black. A diffuse basal black shade. T. a. line diffusely shaded with black. Reniform small, yellowish, more or less distinctly double ringed. Sub-reniform small, yellowish, disconnected with the t. p. line. T. p. line shaped much as in Polygama. Hind wings bright red.

♂. Allied to A. bicarnea Guen,; smaller and distinguishable by the evenness of the t. p. line. Fore wings dead brownish black. T. a. line rigidly oblique to submedian fold, not rounded as in its ally, and with a less prominent tooth on internal margin. A very faint yellowish shading to the line and also on the costa at inception of t. p. line, where A. bicarnea is strongly marked with carneous. T. p. line shaped as in its ally, but even, geminate, the inner line not scalloped; the component lines include a pale shading.

Mr. George Norman has recently taken a number of the species of the genus Lithophane at Orillia. In a recent letter, Mr. Norman records the capture of petulca, ferrealis, disposita, Bethunci, semiusta, and “that lovely oriunda, a single specimen.” Mr. Norman also finds a number of specimens of a large light grey species allied to laticinerea, but differing from that species and cinerea in the position of the stigmata, the color, and the shape of the subterminal line. I propose to call the species Lithophane Georgii, after its discover.

In the Am. Nat., Sept., 1872, Mr. Scudder published an essay entitled “The curious History of a Butterfly,” in which it is stated that in two N. American species of the “genus Brenthis,” namely, myrina and bellona, occurs a phenomenon considered by the author to be quite unique among butterflies : there being two sets of individuals, each following its own cycle of changes,:apparently with as little to do with the other set as if it were a different species; each set having its own distinct seasons and thus giving rise to the apparition of two or three successive broods in the course of the year.

Since the original illustration and description of this species, ten years ago, in the Proceedings of the E ntomological Society of Philadelphia, it has not been noticed, except by the late Mr. B. D. Walsh, in the same Proceedings, vol. 5, p. 194-5. I have been since last year indebted to Prof. C. V. Riley for a number of specimens of perspicua, raised from larvæ found on Sumach. It is enough to say that the specimens bear out the specific validity of a form which is perhaps the most easily recognized among the difficult species of this genus.

A male specimen taken by the late Mr. C. T. Robinson, at Brewster's, N. Y., varies by the fore wings being black, the veins broadly bordered by flesh color. The ordinary triangulate black interspaceal markings have all fused. Hind wings shaded entirely with blackish, none of the usual spots being visible. Beneath as above. Body as in the type.

Eyes naked, with short lashes. Antennæ in the female simple. Palpi gray, the third joint very short. Collar whitish beneath, above bearing a transverse, partially interrupted black line. Thorax mingled light and dark gray; no prothoracic tuft, metathoracic tuft low and longitudinally furrowed; sides of the thorax deep black and very conspicuous. Abdomen light gray, with several slight dorsal black tufts, and one very strong one, tipped with white on the third segment.

As supplementary to my remarks on this pretty creature in the August number of the Can. Ent., I would say thaton June 6th a friend gave me a captured female Luna. For two or three nights I used her as a trap to entangle unwary males, but in vain as far as my cabinet was concerned; the weather was cold. On the 7th,8th and 9th, during the silent watches of the night, she deposited in her place of confinement, in all, about 100 eggs of a dark brown or chocolate color, flattened at the sides, smooth and about .005 of an inch in length: the sides were of a lighter shade.
