Head: Light gray-green, of a slightl}' bluish cast, the crown mottled with a mosaic of white. Ocelli: The lower two show some black shading, the remainder being translucent. There are a number of whitish setae arising on the face, and a few shorter setae of similar character occur on the bod\-. A lateral view of the mature larva is shown on Plate 17. Pupa: Length, 21 mm. Color, uniform red-brown through- out, overlaid by a barely perceptible bluish bloom. The shape is sub-cylindrical, stout, the head well rounded and relatively small. The body is widest in the region of the posterior edge of wings, and tapers gradually from that point to the cauda. The surface is smooth and glistening, without any prominences, ridges, or rough- ened surfaces, and lacks any vestige of setae. Spiracles, a shade darker than body color, but relatively inconspicuous. Cremasteric end rounded, and topped by a single stout spur, without a recurved tip. Pupation occurs on the ground under debris, in a loosely woven cocoon into which gravel, soil, and plant fragments are incorporated. All of our examples pupated prior to June 2, 1939. The pupa is illustrated on Plate PLATE 18 Pupa of Trachea fumeola Hamps. Enlarged approximately by 3^2- Photo courtesy Los Anireles County Museum. 107.
