The legs have short, blackish or brownish hairs, coxæ pale-haired; front coxæ with some bristly hairs at the apex, hind coxæ with a small bristle on the outside, all pale; the front metatarsus is slightly excised below and has on the basal half a row of longer hairs; middle femora with four bristles below at the base, the two middle the longest; the middle tibiæ have two antero-dorsal and one postero- dorsal bristle, and two ventral bristles in the middle; hind femora with longish hairs above; the hind tibiæ are somewhat short, slightly thickened; they have in the middle, in a very slight emargination, a number (probably six or seven) of flat bristles, which are thickened towards the end; the bristles are very close- standing and therefore not easily counted; just below these bristles there is a tuft of longer, somewhat curled hairs, which may be somewhat coalesced; between this ornamentation and the apex are two long bristles; besides the hind tibiæ have fine, longish hairs on the postero-ventral side, some hairs and bristles above, and some bristles on the basal half of the anterior side; the posterior femora have a preapical bristle; hind metatarsus as long as the second joint, with longish hairs and some bristles below, longest at the base.
