Mr. Wm. Saunders has collected a species of Crambus, which is apparently unnoticed by Prof. Zeller or Dr. Clemens, who have written most frequently on our American species. The new species, which I call C. interruptus, is very easily recognized and has been figured by Prof. Townend Glover on his Plates of Lepidoptera. The head is white ; palpi inwardly and beneath white, outwardly dark brown. Thorax white, patagia bright brown. Hind wings and abdomen pearly gray. Fore wings bright brown with a longitudinal white median band obliquely interrupted at the middle of the wing by the ground color.

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.

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.

General color light brown. Upper part of pronotum and hind femora with a reddish tinge. Face sometimes mottled. Antennæ light brown infuscated apically. The usual black band behind the eye broad and distinct, and reaching last division of pronotum, bounded below by a narrower white stripe. A broad white stripe from base of elytra connects with a white stripe at insertion of posterior femora, forming a right angle. Outside of hind femora is crossed by two indistinct dusky bands that extend upon upper edge. Lorver sulcation reddish. Knees black. Hind tibiæ blue. Elytra light brown with very small black spots in the disk.

Last fall I obtained a few eggs from a female L. proserpina, in Sept., while in the Catskills, and raised eight larvæ to hybernation, which took place after third moult. This spring I have carried four of these to maturity with the following results : 'fhe first chrysalis gave butterfly this morning (April 29th), a male arthemis. For some hours before the emergence the white band of arthemis was distinctly seen through the wing case. The second was but a few hours younger and during this afternoon has given proserpine male. I expected this, as here there was no white band on the wing case.

Center is situated on the line of the New York Central Railroad, midway between Albany and Schenectady. The road in reaching this point traverses a distance of eight miles from Albany, and attains an elevation of 315 feet above tide-water.

During the warm months there are two daily trains stopping at this station, going east and west, and are so arranged as to give the scientist the advantage of the first half of the day on the ground. The place itself is not in the least attractive, consisting of but a few dwellings erected for the accommodation of the Railroad employes.

This genus of Geometræ resembles Tornos; the fore wings are larger and with the apices more produced; the external margin is longer and more oblique. The hind wings are narrow and lanceolate, with the apices pointed and a little depressed ; external margin straight or a little incurved. The female abdomen is like that of Tornos, and is thickly tufted at the extremity. This singular genus, which I name for Mr. Meske, may be at once distinguished by the pointed secondaries, narrower in proportion than in any other genus of the group, while the primaries are disproportionately large with straight costa and produced apices.
