The wings of the moth when fully expanded (PL I, c) meas- ure about nine-tenths of an inch. These are very dark brown in color with an opalescent or silvery reflection, and are bordered with white. The forewings in both sexes have two nearly oval white spots, while on the hind wings of the male there is one spot, which, in the female, may be divided. The body is black, crossed by two white bands in the female and by one band in the male. The male antennae are thickened or knotted near the middle, while in the fe- male (PL I, 5) they are uniform and thread- like. THE EGG. The egg of the grape leaf-folder (fig. 2, a; PL I, a) is eUiptical in out- line and very minute, measuring about mm. in length. Its membranous chorion, or outer covering, pre- sents under high mag- nification dehcate hex- agonal markings. THE LARVA. The larva, when fully grown (PL I, li; PL II, h) is about an inch long, is widest in the middle, and tapers toward either end. It is glossy, translucent yeUow-green on the sides and somewhat darker above, with scattered fine yellow hairs on each segment. The head and prothoracic shield (PL I, /, Ti) are fight brown, and there are light-brown spots on the sides of the first two thoracic Fig. 2.—a, Egg of the grape leaf-folder showing larva just before hatching; 6, newly hatched larva. Greatly enlarged. (Original.) THE PUPA. The average pupa of Desmia funeralis is a fittle over half an mch long (PL I, d). The fight-brown color shown just after pupation soon turns quite dark. The pupa tapers characteristically toward the posterior end, where an 8-hooked cremaster is Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly res
