Insects. decreasing in thickness, the terminal being conical and terminating in a blunt point, the lobes are thick, terminating at tip in a corneous, acute, curved process: the inner side being densely set with equal spinules rather than hair: the ligula is thick, densely set with spine-like hair, a small tubercle bearing two longer hairs in the centre, and the two-jointed palpi at sides: the legs are short, fleshy, densely set with long strong spines. The antennae of the $ imago are stouter and comparatively shorter than in elaphns the club is heavier, more compactly set, proportioned as shown in figure 2, joint six is dilated at tip and shows an incipi- ent pectination; joints i to 6 are entirely glabrous, joint >7 has the prolongation only opaque pubescent, while 8 to io are entirely opaque and pubescent. The 0 differs in having the 7th joint entirely glabrous, and in the somewhat heavier joints of the club. 3. mazama, Lee. (Dorcus) Proc. Ac. Phila. 1861. p. 345. The lab- rum of $ is rectangular and about four times broader than long; the thorax is distantly punctured and nearly smooth at disc; near the suture of elytra are two striae, obliterated toward apex. The $ antennae are still shorter than in dama, the joints 1 to 6 glabrous, 6 a little dilated; 7 glabrous at out- er side only, prolongation half as long as in 8 and. opaque pubescent, 8 to 10 entirely pubescent, opaque.

The elytra and the thorax are more distinctly punctured, than in any of the other species, heavy mandibles, rectangular at the base and only curved at tip while the other species have them more equally round- ed; near the middle tooth of mandibles, there are in the $ three, in the y two smaller ones.
