Fig. 33. like a dog's tail; as the larva grows older it changes to a reddish-brown, and by the third month it entirely loses the caudal horn. It measures when full-grown nearly four inches; it crawls by a series of sudden jerks, and flings its head savagely from side to side when alarmed. The body is pinkish on the back, the sides a darker shade. On the segments six to ten inclusive are five cream-yellow patches, with a black annulation; on seg- ments two to six are numerous small black dots, but on the remaining segments only two; the head reddish-brown. The most common general colour of the full-grown larva is a rich velvety brown—vinous brown. It feeds on the leaves of the grape vine and Virginia creeper. They consume great quantities of leaves, often stripping bare the branches they attack. The pupation occurs, according to Mr. Lintner, in a ground cell, constructed at a very moderate depth. The chrysalis is chest- nut-brown, about two inches long, with a long thick terminal spine, slightly forked; the moth generally appears the following June. The moth (fig. 32) expands from four to five inches, and is of a light olive colour, variegated with patches of darker olive-green; the antemise long, slender, and tapering at the extremity into an ample hook, with seta or bristles. This form of the antennae is characteristic of the genus. 16. Philampelus achemon, Drury. Sphinx achemon, Drury. " crantor, Cramer. " " Fabricius. " " Abbot and Smith. ? Pholus " Hubner.
