. The butterfly book; a popular guide to a knowledge of the butterflies of North America. Butterflies. Genus Pyrrhanaea. Fig. hi. —Neuration of the genus Pyrrhancea. Caterpillar.— Head somewhat globular in appearance; the an- terior portion of the first thoracic segment of the body is much smaller in diameter than the head; the body is cylindrical, tapering to a point. —Short, stout, with trans- verse ridges above the wings on the middle of the abdomen, keeled on the sides. The cremaster is small and furnished with a glob- ular tip, the face of which is on the same plane as the ventral surface of the body, causing the chrysalis to hang somewhat ob- liquely from the surface which supports it. This is a large genus of mostly tropical species, possessed of rather singular habits. The caterpillars in the early stages of their existence have much the same habits as the caterpillars of the genus Basilarcbia, which have been already described. After passing the third moult they construct for themselves nests by weaving the edges of a leaf together, and thus conceal themselves from sight, emerging in the dusk to feed upon the food-plant. They live upon the Euphorbiacece, the Lauraceat, and the Piperacece. The insects are double-brooded in the cooler regions of the North, and are probably many-brooded in the tropics. (i) Pyrrhansea andria, Scudder, Plate XXIV, Fig. i, $ (The Goatweed Butterfly). Butterfly, $.— Solidly bright red above, the outer margins narrowly dusky on the borders. On the under side the wings are gray, dusted with brown scales, causing them to resemble the surface of a dried leaf. ? .— The female has the upper side paler and marked by pale fulvous bands, as shown in the plate. Expanse, $, inches; $, inches. Early Stages.— In Fig. 21, on p. 9, is a good representation of the mature caterpillar, the nest which it constructs for itself, and the chrysalis.
