The perfect beetle (Fig. 178, d), when seen in all its splendor, is one of the most beautiful objects that can well be imagined. It exact- ly resembles a piece of golden tinsel, and with its legs withdrawn and body lying flat to a leaf, the uninitiated would scarcely sup- Coiors-(c) brown; (rf) golden, pose it to be an insect, did it not suddenly take wing while being ob- served. At first these beetles are of a dull deep orange color, which strongly relieves the trans- parent edges of the wing-covers and helmet, aud gives conspicuousness to six black spots, two (indicated in our figure) above, aud two on each side. But in about a week after they have left the pupa shell, or as soon as they begin to copu- late, they shine in all their splendor, aud these black spots are scarcely noticed. The Pale-thighed Tortoise-beetle. {Gassidapallida, Herbst.) This species can scarcely be distinguished from the preceding. It is of a somewhat broader, rounder form, and diffei's in lacking the black spots on the wing-covers, and in having the thighs entirely pale yellow, while in aurichalcea they are black at the base. It likewise feeds upon the Sweet-potato, and its larva differs only from that of the former, in its spines being brighter and lighter colored, and iu having a dull orange head, and a halo of the same color on the anterior portion of the body. The Mottled Tortoise-beetle. (Gassida guttata, Oliv.*) [Fig. 179.]. cl Colors— (a and h) green; (d) gold and black. This species (Fig. 179 d), which is the next •I'his species, as we ai'e informed by Dr. Le Conte, is referred by Boheman to the genus Cofitoci/cia, which differs from Cassida by more slender, not distinctly clavate and nearly filiform antenna'. Dr. Conte has kindly promised to furnish us a synopsis of our carsidjE, which we h
