Pale cream color, somewhat acuminate-ovate, broadly rounded at head and thorax. Prothorax, from the lateral view, triangular, the dorsal surface being the base of the triangle, which is very broad and convex. Antenna passing upward at side of eye, between margin of prothorax and front femora, thence to dorsum, curving backward over base of wings. Wing-pads long and narrow, covering posterior legs, with the exception of the last three tarsal joints; front wings nearly covering hind ones. From the ventral aspect (fig. 4): The front of head is in almost direct line with the body; mandibles small and not closed; palpi widely separated and extending beyond front tibiae. Femora of first pair of legs directed dorsally, tibiae resting on middle femora; first tarsal joints resting under tip of palpus; tarsal joints then extending caudad, almost parallel, except last two joints, which slightly diverge. Femora of second pair of legs parallel to femora of first pair, second tibiae, however, forming a greater angle with their femora than tibiae of first pair of legs; second femora and tibiae resting upon wings for a part of their length; tarsal joints gradually converging un- til the last two, which nearly touch between wing pads. Third pair of legs covered by wing pads, with exception of last two joints and a part of third; last two parallel, touching, and extending to middle of sixth abdominal segment. Dorsal surface of the first six abdominal seg- ments almost flat, and in the third, fourth, fifth, and sixth segments the surface produced laterally into a fleshy fold projecting over side of abdomen, the anterior margin of which is rounded and the posterior square, giving the abdomen a notched appearance; in center of each projection laterally is a group of recurved bristles.
