I am now able to give the results of my attempts at raising the caterpillars of the three Argynnides, Cybele, Aphrodite and Diana, from the egg, this past season. In August and. early in September, 1873, females of cybele were easily obtained, and a few of aphrodite, which is a rare species here, and these were shut up in kegs, within which were placed pots of growing violets. The eggs rvere laid abundantly on the leaves and stems, and on the cloths which covered the kegs.

Expands I 4/5 inches. Primaries light gray, the outer third brownish, with a triangular gray spot near the apex. A narrow black line near the base of the Wing extends from the costa to the submedian vein. Parallel to this and farther out, a black patch, narrowest at the costa and broadest on the second median veinlet, extends nearly across the wing. ending at the submedian vein. A triangular black patch surrounds the brownish reniform spot, and immediately back of this a curved black line reaches from the sub-dorsal vein to the second median veinlet.

The third and concluding part of Kaltenbach's work (Die Pflanzenfeinde aus der Classe der Insecten), has just been received in this country, and contains the following notices of the food plants of European, butterflies, in addition to those previously given. The numbers in parentheses refer to the former list.

Slate color, tinged with ochreous; apex of the abdomen yellowish ; two longitudinal dusky lines on top of the abdomen, which, however, are invisible in the dead specimen. Al. ex.,6/16 inch. Kentucky.

The case is ochreous, slender, cylindrical, tapering a little to each end, and compressed or pinched at the posterior end, so as to divide it into three small ridges. It is about half an inch long, and was found adhering to the bark of sugar trees (Acer saccharinum.)

Among the material submitted to me for determination by Professor Packard, from the Peabody Academy of Science, are specimens from Maine and Massachusetts of two species of Agrotis allied to, but distinct from A. triangulum. Agrotis attentus. N. sp.

The eyes are naked. The middle and hind tibiae are armed, but the fore tibiae are without spines; male antennae siurple, bristled and pubescent.

On April 18th of this season, while searching for insects on Montreal Mountain, I found under a stone at the foot of a hickory tree, a larva, of which the follorving is a description :

Length two inches. Form cylindrical, slightly annulated. Head reddish yellow, with two brown streaks, and marbled with lines and dots of the same color ; semi-tlansparent, shiny, slightty bilobed, with a few scattered hairs of a whitish brown color. Mandibles brown.

The species belonging to this sub-tribe, although small in number, rank with the rarer forms of Carabidæ : they may easily he known by their glabrous body and the confluent eighth and ninth striæ of the elytra. Several of the Oodii bear a superficial resemblance to certain Amara allied to fallx. With one exception ( O. elegans) the species are all Atlantic, occurring more abundantly southward. Oades fluvialis must be considered a typical northern Species, occurring rarely near St. Louis, Mo., but more abundent at Rock Island, Ill.
