Egg laid July 16th, on grass, the female being confined in a bag over a tuft of grass set in a flower pot. Shape nearly that of a semi-ovoid, the base being flattened and the sides at base rounded, the surface under a low power smooth, but under a higher seen to be covered with shallow thimble-like depressions : color greenish-white.

Hatched July 20th.

Young larva–Length 0.09 inch.

My knowledge of this genus is derived wholly from Prof. Zeller's paper. It is equal in part at least to Holcocera Clem. (I have to thank Prof. Riley for calling my attention to the fact that in some of my references to this genus the name is incorrectly given as Holocera.)

B. sciaphilella., as described and figured, differs from H. triangularella Cham. as to the position, size and form of the triangular spots on the wings. Sciaphilella has distinct opposite, comparatively small costal and dorsal triangles, while triangularella has no dorsal triangle, but a single large costal one, wide upon the costa and crossing the fold, and it also has the apical part of the wing distinctly streaked and clouded with brownish gray.

Male–expanss 1.1 inch.; size and shape of Leonardus, the hind wings somewhat less prolonged anteriorly.

Upper side of both wings light glossy brown ; primaries have five translucent spots, namely, one sub-apical, oblong, narrow, cut into three equal parts by the subcostal nervules; three discal, the first being at the top of the upper median interspace, small, semi-ovall the next large, irregularly qyadrate, crossing the next lower interspace, and the third on sub-median interspace, less transparent, more yellow, in one example clearly defined, sub-triangular, in the other diffuse; these three spots forming an oblique line back of and below the cell.

I am but imperfectly acquainted with this genus, knowing it only through the Nat. Hist. Tin,, vol. xi. ; andl the plan of that work does not seem to admit of details of structure. If it is equivalent to Aechmia, Perittia, Tinagma and Douglassia combined, as those genera are limited in Ins. Brit., v. 3, then the proper place for this species is in it. But if, as I conclude from the account in Nat. Hist. Tin.. it is the equivalent of Tinagma alone, and the other groups above mentioned are good, distinct genera, then this species, while possessing affinities with all, would be out of place in either.

Five years ago, I discovered at Center, in the trunks of poplar trees (Populus tremuloides) several pupal cases of a Cossus, which, by their differing from the other cases known to me, of C. Robiniæ and C. querciperda, I had reason to believe was an undescribed species. This year, on the 14th of June, on examining some infested trees, several pupal cases were discovered projecting half-way from the trunks, and an imago, which had apparently just emerged, and was resting on the stump of a broken limb. The colors of the moth so exactly simulated the surface on which it rested that it was with difficulty observed, even when looking directly at it.

In a paper on the Noctuidæ of North America (6th Ann. Rep. Peabody Acad. Sci.) I have stated that we should rather expect the acquirements of fresh character to be more apparent during the period of growth of the Lepidoptera. I have elsewhere (Bull.Buff. Soc., 1, 130) shown that there is proof in the excessive variation in the larvæ of a genus where the adults of the species are remarkably uniform in color and ornamentation, that the larva submits to independent and wide modification from the circumstances of its environment.

With ten specimens of fasciella and two of 5-notella before me, with scarcely a trace of variation in the ten, but with the two differing from each other somewhat and both differing very decidedly from the ten, I had no doubt as to the distinctness of the two species. A larger series, however, induces the belief that they belong to the same species. The difference between them may be thus stated: In fasciella the base and apex of the fore wings are brownish-gray, and between these portions are three brownish-gray and four white fasciæ, all very distinct and well defined. ln 5-notella the whole dorsal half of the wing is white, there is a small brown spot on the base of the costal margin, another further back, and stil1 further back another which in the middle of the wing is produced backwards to the gray-brown apical part of the wing, which encloses two small white costal streaks.

This species has the thoracic vestiture mixed with hair-like scales, and it agrees in all respects with C. iaspis as to structure and pattern of ornamentation. It differs from Bryophila lepidula in these respects and in that the abdomen is more strongly tufted. I have taken all these species in June and July in the vicinity of Buffalo.

The following species, new to the fauna of the United States, have been collected by Mr. L. Heiligbrodt, in Bastrop Co., Texas, and the types are contained in the beautiful collection of my friend, Mr. Otto Meske, in Albany.

Anisota Heiligbrodti, n. s.

♂ ♀. The antennæ of the male are broadly bipectinate, except at the tips ; those of the female are simple. This species differs from its allies by its purely gray color and by the fore wings being covered by two narrow blackish lines. The first of these is sub-basal, irregularly sinuous, produced on the disc; the second is regularly scalloped, interspaceally waved, and runs from apical third to internal margin. The wide median space has a more purely whitish ground, while the wing everywhere is thickly dusted with duskily cells.

The object of this notice is to call the attention of American Entomologists to a most excellent and complete “Revision of the Family Sphingidæ,” by Arthur G. Butler, of the British Museum, which has appeared in the Transactions of the Zoological Society, London, in quarto form. A proper arranqement of the Sphingidæ of the world is a work requiring both extensive material and great experience and tact, of which Mr. Butler has shown himself to be equally possessed.

This species is similarly sized with y-inversa, or perhaps a little larger. It is less brightly colored. The fore wings are dusky ochre with two blackish lines ; the first crossing the wing a little obliquely at the middle; the second before the apex from costa to external margin. The lines do not meet at costa as in its ally. The space between the lines is discolorous, being somewhat grayish. Hind wings more yellowish, concolorous. Beneath immaculate, like hind wings above. Thorax like fore wings. Antennæ simple.

This form, or species, belongs to the series of walkeri and vinulenta, of the former of which I was at first disposed to consider it a variety. It is distinguished by the presence of all three of the ordinaly spots. Rusty ochre; t. a. line single, evcn, blackish with the small rusty outlined claviform attached. Orbicular rusty-ringed, with pale centre, sma11. Reniform pale ochre, rusty-ringed, well sized, of the ordinary shape, with a black inferior stain. Median shade a little waved, joining the reniform above and issuing from it inferiorly.

Egg–1/18 in. diameter; light green, translucent, smooth, circular, oblate or depressed. Hatched in nine days from extrusion. Larva–¼ in. long; light green, slender; head large, round, slightly depressed medially ; face pink, with a purplish tinge; extremity of the body dark sea-green, with a large wart or tubercle, pyramidal in form, upon which rests the horn.

My observations on both of these species scarcely permit me to doubt that their larvæ feed in some way on the Honey Locust (Gleditschia tricanthos), though neither of them has been bred from the larva. I have, however, met with a larva from which I have not succeeded in breeding the imago, and which I believe to be the larva of one of these species. It is a Gelechia-like, about half an inch long, with sixteen feet, and feeds inside the seed-pods of the Gleditschia, on the honey-like substance found in them, and not, so far as I have observed, on the seed.

I have, for three seasons, raised Euchaetes collaris from the larva, it being very abundant in this locality, and present the following notes as the result of my observations :

The larvæ feed on the Apocynum androsaemifolium, or Spreading Dogsbane. They will in confinement feed on Asclepias, but I have never, after careful search, found but one of the larvæ on it in the field. They feed at night, leaving their food-plant and hiding themselves during the day.

The paper relates to the development of one of the most singular and interesting of North American insects–the largest of the Order Neuroptera. In its perfect state this insect is a great, clumsy, nocturnal fly, popularly called Hellgrammite, and charecterized by the jaws of the male being converted into a pair of long, curved, cylindrical and tapering prehensile organs, like the finger of a grain-cradle. In the larva state it is aquatic and much esteemed as fish-bait by fishermen, who call it a “crawler,” “dobson,” etc. Indeed, one of the most popular artificial fish-baits is a patent india-rubber imitation of it.
