Economic entomology for the farmer and fruit-grower : and for use as a text-book in agricultural schools and colleges . is the cecropia, Platysamia cecropia, the caterpillar occurring ona great variety of plants, including many of our fruit-trees and 7HE INSECT WORLD. 281 certain small fruits. It is green, and has six rather prominentwarts on the thoracic segments, of which four are coral-red incolor and the hinder two are yellow, sometimes with a reddishtinge. On the rest of the body are other tubercles which arefurnished with little clusters of spurs and spines. The cocoon issometimes spun in bushes, attached to a twig, sometimes at anangle of a fence, or wherever the caterpillar happens to considerit convenient. The resulting moth is dusky brown and powdery. Fig. 309. %_,^<- ,^ ^^..^k^^,^^^.. Caterpillar of the cecropia moth. the hinder margins clay-colored, a kidney-shaped dull-red spotwith a white centre and a narrow black edging is near themiddle of each wing, and beyond the spot is a wavy dull-redband, bordered internally with white. The primaries near thebase are dull red, and near the tip is an eye-like black spot withina bluish-white crescent. Several other species occur, all moreor less resembling in general appearance the cecropia, and spin-ning much the same kind of cocoon. Of a somewhat difterent type is the poly[)hemus, Telea poly-phemus, which has a green caterpillar without prominent tuber-cles, but with little, black, wart-like processes, giving rise tosmall, stiff bristles. This feeds upon oak and a variety of othertrees, but is rarely abundant, and when forming its cocoon spinsup in a leaf, which later drops to the ground. This cocoon isoval in shape and completely closed, differing from that ofcecropia and its nearest allies, in which it is open at one en
