The genus, like the preceding, is monotypic, and contains but the one species A. odius (Fabricius). It is so striking and so easily recognizable by the figure we give on [Plate LIV] that nothing more need be said, except that it has a wide range through the American tropics, being found in southern Florida and Texas, the Greater Antilles, and from Mexico to southern Brazil. Expanse 3.75-4.00 inches.
Genus PYRRHANÆA Schatz
PL. LV
Medium-sized butterflies. Front wings falcate at apex; hind wings tailed at end of third median nervule. Costal margin of fore wing angulated at base, inner margin straight. Upper side of wings generally fulvous or red; lower side mottled and marked so as to resemble dried leaves. Egg spheroid, flattened at base, depressed on top, marked with a few rows of raised points about summit. Caterpillar with head globular, first segment behind it much smaller than head; body cylindrical tapering behind. Chrysalis short, stout, keeled on sides; cremaster globular at tip, and so arranged as to cause the chrysalis to hang at a slant.
This is a large genus characteristic of the American tropics. The larvæ feed on euphorbiaceous and lauraceous plants, after the third moult making hiding-places for themselves by rolling up leaves and tying them with silk. There are three species in the United States, two of which we figure.
