laterally behind and more convex at apex in the $ ; pygidium vertical 

 in both sexes ; lateral metasternal process sharply bulging ; meso- 

 sternal process blunt, not projecting ; anterior tibiae bi-dentate in the 

 cf , tri-dentate in the 2 \ legs robust, intermediate and posterior tibiae 

 sharply dentate on the upper edge, tarsi moderately long in the J , 

 shorter and more broadly triangular in the female, basal joint shorter 

 than the second ; hind spurs sharp in the 3 , compressed and 

 thickened in the ? . 



In the 3 of this genus, the antennal club is as long and as curved 

 as in the genus Gariep, but the shape of the head and of the last 

 joint of palpi is different ; the facies is also different ; the basal joint 

 of the hind tarsi is shorter than the second, and much more sharply 

 angular outwardly in the manner of Rhinoc&ta ; the 2 is not unlike 

 a 2 Ischnostoma, but the clypeus is similar to that of Bhinocceta 

 cormita.

Black, with the elytra testaceous, but with a sutural and marginal 

 narrow infuscate band in the $ , testaceous and infuscate in the 2 ', 

 antennal club chestnut-brown. 



Male : Head and prothorax, mesothoracic epimera, pectus and legs 

 clothed with a somewhat dense and long flavescent pubescence ; 

 clypeus and head closely punctate, vertex with a small conical projec- 

 tion ; prothorax sub-triangular, sinuate laterally past the median 

 part, moderately rounded above the metasternal epimera, arcuate 

 above the scutellum which is very long and triangular, and coarsely 

 punctate at base, outer margin serrulate ; elytra glabrous, somewhat 

 elongate, deeply sinuate laterally, plainly bi-costate on each side and 

 having faintly seriate, almost obliterated punctures on the whole 

 surface ; the suture is sub-carinate on the median dorsal part ; 

 pygidium impunctate, apical margin of first segment with a fringe of 

 long hairs. 



Female : Head as in the male, but glabrous ; the conical projection 

 on the vertex is blunter ; prothorax glabrous, except along the serrate 

 margin, which is briefly ciliate, ampliated from near the apex to near 

 the median part, nearly straight thence, less straight along the base 

 than in the male, but equally arcuate above the scutellum ; elytra 

 more ampliate rounded laterally in the posterior part, and with the 

 two costules on each side less well defined than in the male ; the 

 punctuation is very slight ; under side less hairy than in the male ; 

 the joints of the tarsi are shorter, the inner hind spur is spatulate at
