Mr. W. L. Courtis, in 1883, sent me many eggs of this species, laid by females confined with Sedum. All the butterflies were of the variety Hermodur, H. Edw., the females being very black. I related Mr. Courtis's observations in Papilio III., p. 158. The eggs were forwarded to Dr. H. S. Jewett, Dayton, Ohio, in default of ice here, and were placed in an ice box in that town, and so remained till late in Jan., '84. I received them 28th. Two days after, several of the eggs were found to have hatched, the day being warm, 55° Far. at noon. I gave the larvæ leaves of our wild Sedum, and also of some cultivated sorts that I had brought together for the purpose. Three days later the wild leaves were noticed eaten or nibbled a little, the other sorts not all. In former years, at least twice, I had had these larvæ out of egg, and they refused our Sedum and starved. In the present case, little holes were eaten on the upper side of leat half way through the fleshy part. Several larvæ died speedily, but a few did well. On 5th Feb'y, two were visibly stouter than the rest. On 6th, I happened on some larvæ feeding, this time at the edges of the leaves. On 8th, the two largest began to swell at second segment; on 10th, one of these died in the effort to moult, the time from the egg being 11 days. On 12th, the other larva passed 1st moult, at 13 days. On 15th, a third passed same moult; next day another, and I was fortunate in seeing the process.

Nemeophila Selwynii, n. sp.

Head, thorax and abdomen, dull sooty black. Palpi, collar and tip of abdomen pale dull orange. Tegulæ, sides of abdomen and upper side of the tip of antennæ sordid white. Wings dull sooty black. At base of primaries a very distinct and clearly marked short white streak, and an oblique band (also cream white) from behind the middle of the costa to near the internal angle. This band, which is excavated at its junction with the cell, gradually narrows to a point as it reaches the outer margin. The fringe is white on the apical half of the margin, black elsewhere, and there is a small orange dash at the base of the costa. Secondaries wholly sooty black, fringe white, a little below the apex. Beneath the wings have a slate-colored shade, the markings of the upper surface repeated, the costa of primaries stained with orange at the base and at the edge of the white oblique band, while that of the secondaries has two whitish triangular blotches.

The following species were collected, from 29th March to 21st June, 1884, along the thirtieth parallel in two neighborhoods, New Orleans and environs, and a district on Bayou la Fourche extending from a little above Napoleonville a few miles south along the bayou. The latter is in Assumption Parish, and at the time of my visit was partially overflowed from the great crevasse of March, 1884. Though many of the species here given are well known to occur in the South Louisiana fauna, I give them all just as I collected them, with the view of noting their relative abundance or rarity, dates of occurrence, localities, etc., all of which together may contribute to make our knowledge of the fauna more complete. But it must be remembered that this is merely a record of how the species occurred to me during my stay, in which I collected only a small part of what might have been taken, could I have given my entire attention thereto. Nearly all those of the N. O. neighborhood were taken between the city and Lake Pontchartrain.

MALE.—Expands 2.2 to 2.4 inches.

Upper side brown-orange, color of C. Californica Boisd.; occasional examples are dark, a dead-leaf-brown over whole surface; hind margins edged by a blackish border, of nearly equal width throughout, and extending to apex of primaries; but sometimes this border is widest on primaries; costa of primaries dark brown; in some examples this shade scarcely if at all crosses costal nervure, in others it encroaches on the cell more or less, and occasionally covers the whole cell; but in nearly all examples under view the cell is concolored with rest of wing; the oblique discal brown band, which is a conspicuous feature in the males of the allied species, does not appear in the present one, so far as the examples show; the coloration of the upper surface resembles that of the female of Californica; on secondaries, the costal margin is edged with brown, and just outside the end of cell is an expansion of this, which forms a large elongated patch, convex on interior side—not at all like the sub-triangular and small patch seen in Californica and Iduna; primaries have a black ocellus, rounded or oval, with white pupil on upper discoidal interspace, and a second on second median interspace, the last one usually blind, but sometimes pupillated; generally the lower ocellus is smallest, but occasionally is equal to the upper; one example under view has two additional black spots, as large as the ocellus on secondaries, one on the interspace next above each ocellus; another has mere points on these interspaces; secondaries have a small ocellus, either blind or with white pupil, in second median interspace; fringes of both wings alternately yellow white and brown-black.

So far my records. From this time the remaining pupæ were taken to a room not heated, and gradually emerged hele, which they would probably have done at about the same time had they never been taken to a warmed room.
