very shallow groove the lower edge of wliich is strongly bi-dentate 

 near the knee, the second tooth being the more developed of the two, 

 and ending in a strong but not very long apical mucro, this edge is 

 serrate and villose ; hind claws slightly cleft inw^ardly towards the 

 median part ; the two basal teeth of the anterior tibiae are very short, 

 and strongly oblique. 



Female : Light chocolate-brown and entirely clothed on the upper 

 side with appressed, very closely set, squamiform greyish hairs 

 which are, however, somewhat flavescent in the median groove, 

 the hairs on the pygidial part are similar to those on the elytra, 

 but those which cover the whole of the under side are more 

 scale-like.

Male : Black, with the prothorax and the elytra covered with con- 

 tiguous round orange-yellow scales ; head very rugose, briefly 

 pubescent, clypeus very rounded laterally at tip and with the 

 margins almost non-reflexed ; prothorax veiy diagonally narrowed 

 laterally in the antei'ior part, rounded and non-emarginate in the 

 posterior, not distinctly grooved longitudinally in the centre, and 

 fringed along the anterior and the lateral margins with long black 

 liristles : scutellum somewhat small and almost ogival ; elytra 

 moderately attenuate laterally towards the apex, non-costulate, and 

 having along the suture, immediately below the scutellum, a fascicle 

 of very long black bristles and a series of short ones following the 

 suture, as well as some hardly distinct rows of similar but still 

 shorter bristles projecting from between the scales ; pygidium and 

 underside scabrose, glabrous ; hind femora greatly developed and 

 having inwardly near the apex, at a short distance from the knee, 

 a very long, sub-horizontal, robust spine hamate at the tip, the 

 trochanters are not spinose, the hind tibiiE are curved, not quite as 

 long as the femora, not grooved inwardly and they end in a very 

 robust, sharp, apical mucro; the claws of the anterior and inter- 

 mediate legs are distinctly double, the inner one being nearly thi-ee- 

 quarters of the length of the outer, both are cleft ; and the hind 

 claws are simple and single. 



Female : Covered like the male with contiguous orange-yellow 

 scales on the elytra and the prothorax, but having in the discoidal
