a long, sharp spine, femora broad and thick, deeply emarginate 

 beneath ; inner part of tibia produced inwardly at the tip into a 

 compressed lamina dented at each end and with the apical upper 

 part developed inwardly into a sharp spine reaching as far as the 

 base of the fifth joint of the tarsi the four basal joints of which are 

 distinct, but apparently soldered, the fifth joint is as long as the 

 other four, and has three not very distinct denticulations beneath, 

 the claw is as long as the fifth joint, and is very bluntly dentate 

 underneath ; in the female the trochanters are also spinose, but the 

 tibiae are not much inflated, the apical spur is distinct, whereas in 

 the male it has disappeared altogether ; the four joints of the tarsi 

 are elongate, but the fifth is as long as the other four, tri-dentate 

 beneath as in the male, and the claw is as long as the fifth joint, but 

 is not bluntly dentate beneath.

Head and prothorax black and covered with dense fuscous hairs 

 interspersed with moderately dense somewhat flavescent hair-like

 brown, covered with ashy-grey scales, and having on each side one 

 distinct median blackish round spot and another one somewhat in- 

 distinct ; legs piceous, pygidium covered with yellow scales ; clj'peus 

 very acuminate, l)i-dentate at tip ; prothorax very much attenuated 

 laterally in front, not sinuate ; scutellum very long and sharp, 

 twice as long as broad, covered with greyish- white scales; elytra 

 ampliated laterally, humeral callus much developed and produced 

 as far as the median part of the disk, there are two elongate 

 depressions on each side of the base, and a smaller and rounded one 

 near the suture at about the middle, this round depression is 

 blackisli, while the rest of the surface is covered with lanceolate 

 greyish-white scales not set close to each other, in a line with this 

 median depression there is a smaller one, distinctly punctate, which 

 is also blackish, but is somewhat indistinct ; abdomen clothed with 

 yellowish scales and greyish hairs ; pectus very hairy, legs strongly 

 bristly, anterior tibiae with three apical connate outer teeth ; 

 posterior femora of male thick, tibiae simple, much thickened close to 

 the base, sub-parallel, slightly sinuate on each side at the apex, stiffly 

 bristly, and with the apical spur distinct, basal joint of tarsi nearly 

 obliterated, fifth joint longer than the three preceding, tri-denticu-
