Mentum mobile, twice as broad as long, much rounded laterally, 

 slightly sinuate at middle at apex, ciliate there, broadly and closely 

 foveate in its outer face ; ligula bi-lobate, the ciliate part of the lobe 

 projecting beyond the mentum ; maxillfe ending in a sharp hook in 

 the male and very densely penicillate above the hook ; palpi as in 

 Colop]io)i ; mandibles short, robust, arcuate, not as long as the head, 

 bluntly bifid at tip with the upper tooth reflexed in the male ; head 

 transverse in front Init with the genge projecting from near the 

 anterior angle almost in a line with it, eyes deeply divided by the 

 genae which project much beyond it ; the head is somewhat deeply 

 set in the prothorax and has two small tubercles, one on each side ; 

 labrum very small and arcuate ; club of the antennae formed of three 

 long pectinate joints, and as long as all the intervening joints except 

 the basal one which is as long as all the other joints put together ; 

 prothorax a little rounded laterally and slightly wider at base than 

 at apex ; scutellum very rounded at tip ; elytra closely punctate, not 

 striate ; anterior tibise spinose from elbow to apex, the two apical 

 spines stronger than the others, intermediate and posterior ones 

 pluri-serrate ; tarsi a little shorter than the tibiae ; prosternal inter- 

 coxal process rounded, not projecting ; upper side clothed with 

 squamose hairs, denuded here and there so as to form somewhat 

 regular designs. 



I do not know the female. 



This genus seems to be restricted to the eastern part of South 

 Africa, but it will most likely prove to occur north of that limit.
