The pupaand moths are best described by stat-ing that they bear a close resemblanceto the Noctuids, for which they areoften mistaken. Ccelodasys (Notodonta) unicornisSmith derives its specific name from the horn on the back ofthe caterpillar, and its generic name from the large conical tuftof hairs on the under side of the prothorax. The moth is lightbrown, with irregular green patches on the fore Avings. Thecocoon is thin and parchment-like, and the caterpillars remaina long time in their cocoons before changing to pupre. Nericehidentata Walker (Fig. 224) is a closely allied moth. Edema. Fig. 225. 2J3 .alhifrons Smith (Fig. 225) is known hy the costa being whiteon the outer two-thirds. It feeds on the oak, to which it is oc-casionally destructive. Mr. Riley (American Entomologist,vol. i, p. 39) describes the larva as being of a bluish whiteground-color, marked longitudinally with j-ellow bands andfine black lines, with the head and a hump on the eleventh seg-ment either of a light coral or dark flesh color. It generall}^elevates the end of the body. It pupates during the last ofSeptember, the moth appearing about the middle of April, inthe vicinity of Chicago. Platypteryx, a small gcometra-like moth, with its broad fal-cate wings, seems a miniature Attacus. Its larva is slender,with fourteen legs, and naked, with several little prominenceson the back, and the tail is forked likeCerura. The pupa is enclosed in
