narrowed laterally in the anterior part, and not sinuate in the 

 posterior, hind angles broadly rounded, base nearly straight ; 

 scutellum long and sharp ; elytra elongated, narrowing behind, 

 plane, pluri-costate ; sternal process long, aculeate, and without 

 suture ; anterior legs tri-dentate, intermediate and posterior ones 

 uni-dentate ; tibiae sparsely ciliate inwardly. 



This genus includes one species only, originally described from 

 Nyassaland.

Shiny, black, but occasionally rufescent, especially the elytra ; 

 clypeus with broad but shallow fossae in the anterior part, and 

 shallow impressions in the posterior, somewhat villose in the apical 

 part and also on the vertex ; prothorax covered with fairly deep 

 punctures which are broader and more elongated on the sides, the 

 outer margin is slightly serrate ; scutellum sunken, impunctate ; 

 elytra deeply striate and with the intervals plainly raised ; pygidium 

 aciculate ; under side glabrous, except on the femora ; sternal process 

 grooved longitudinally as far as the prosternal part which has no 

 suture, the whole median part is impunctate ; legs and sides of 

 pectus roughly punctate. 



Feeds on gum of Acacia and Combretum (G. A. K. Marshall). 



Length 18-24 mm. ; width 10-12 mm.

Sub-Tribe LEUCOCELITES. 



The insects grouped in this Sub-Tribe are distinguished by the 

 sculpture of the elytra. There is always a basal longitudinal 

 impression inside of the humeral callus, the first, or the first 

 and second dorsal intervals begin with two rows of punctures 

 which from the median part to the apex turn into two geminate 

 impunctate striae ; these geminate striae may not be always well 

 defined in the second interval, but they are always clearly seen 

 in the first. There is a tendency for the first costa or cos- 

 tule to disappear after the median part, the exception among 

 the South Africa genera being Clinteroides and Tephrcea, but these 

 two genera form a connecting link with Pscudoclintcria, and thus
