Thorax.—The color-pattern of the dorsum of the first and second segments is shown in figure 79; the under side is weakly chitinized, except for the horn on the first segment; the third seg- ment above is weakly chitinized, except for a median glabrous spot near the cephalic margin, on each side of which there is a dark-brown mark, bearing five or six seta;; farther back and slightly more remote from the median line there is a triangular spot bearing about ten setae; on each side of the segment there is an elongate glabrous area marked with several brown spots, the cephalic of which bears about a dozen setae; the second and third thoracic segments bear numerous minute spines which, for the most part, point forward. 58.
