Most of our species of tortoise-beetles are of moderate size, measuring about one fourth inch or even less in length. These represent two genera, Cassida (Cas^si-da) and Coptocycla (Cop-toc^- cla). These genera can be separated by the length of the antennae, which extend beyond Fig. 708. the base of the prothorax in the latter (Fig. 708), but do not in the former. The Argus-tortoise, Clielymorpha argus (Chel-y-mor'pha ar'gus), is a large brick-red species, which measures from three eighths to seven sixteenths of an inch in length, and has the prothorax and wing-covers marked with many black spots. This species feeds on milkweed (Asclepias), Family Bruchid^ (Bru'chi-dae). The Pea-zveevil Family, These are small beetles, the larvae of which live in the seeds of leguminous plants. The head of the adult is prolonged into a broad beak ; and the T wing-covers are rather short, so that the tip of the abdomen is always exposed (Fig. 709).
