with numerous somewhat scattered punctures. The scutellum 

 is fulvous. The elytra have at their base numerous small, 

 black, shiny granules, which posteriorly are replaced by 

 punctures ; the latter, gradually becoming smaller, extend as 

 far as the apex. The pubescence on the elytra is of a mixed 

 colour, the prevailing tint being a light chocolate-brown, 

 interspersed here and there with a pale grey ; towards the 

 base it is tawny, mixed around the scutellum with dark brown ; 

 of the latter colour there is a distinct but irregular patch on 

 each elytron behind the middle. The legs and underside of 

 the body have a uniform greyish-brown pubescence. In the 

 male the antenn£E are fuscous ferruginous, more than twice as 

 long as the body, with the third joint thickened and slightly 

 arcuate ; in the female they are very little longer than the 

 body and the joints from the tliird are paler coloured at their 

 bases. The sternal processes are simple. 



Of the three specimens in the Museum two from Chevrolat's 

 collection are ticketed India, the third is referred to Gaboon. 

 The latter locality is more probably the correct one. 



In structure and fades the species agrees best with African 

 forms of Monohammus ; its thorax is punctured, tubercled, 

 and clothed with pubescence almost exactly as in some speci- 

 mens of M. TuspatoVy Fabr.

Niger ; capite, thorace, antemiis, pt'dibus et corpore subtus omnino 

 muriuo-pubesceatibus ; capite et prothorace disperse punctatis ;

 seriatim punctatis, disperse murino-pubcscentibus, apicibus trun- 

 catis ; autennis {S) corpore sesquilongioribus, articulis tertio 

 quartoque paullo iucrassatis.

The pubescence of a mouse-grey colour, uniformly covering 

 all parts except the elytra ; on the latter it is scattered, with 

 a somewhat larger patch on each behind the middle. The 

 punctures on the head and thorax are small and scattered, 

 those on the elytra, slightly granular at the base, are some- 

 what larger and seriately arranged along the middle of each, 

 and extend up to the apex.
