median, shallow impression with the anterior margin tuberculate in 

 front in both sexes ; scutellum with a double row of punctm-es nearly 

 obliterated at the base ; elytra moderately obliquely ampliated 

 laterally from the shoulder to a short distance from the middle, and 

 obliquely attenuated from there to the apical part ; the humeral 

 callus is distinct, but only slightly prolonged towards the median 

 part of the disk which is not costate, the supra-apical callus is 

 distinct, the surface is deeply but not closely punctured, each 

 puncture bearing a very small bristle ; propygidium and upper sides 

 of abdomen clothed with yellow scales ; pectus and legs clothed 

 with black, or fulvous dense hairs ; pygidium sloping forward and 

 abdominal segments constricted in the male, the hind femora being 

 greatly thickened and the tibiae convex, tectiform, broadly scooped 

 beneath, and with the apices greatly produced, the inner one into a 

 very long, broadly spiniform process, and the outer into a blunter 

 but also long process, scooped inwardly and tri-dentate at tip ; there 

 is no trace of an apical spur; the four basal joints of the tarsi are set 

 very closely to one another, the fifth has a small but distinct tooth 

 beneath, and the claw which is as long as the five joints taken 

 together is strongly sinuate at tip and somewhat slender. In the 

 female the elytra are slightly more parallel, and the hairs on the sides 

 of the abdomen are very dense and very long.
