Head coarsely punctured and without frontal carinas. Rostrum 

 with large scattered punctures, its dorsal margins subcostate and 

 with a short longitudinal impression adjoining them exteriorly. 

 Prothorax dorsally broader than long in $ , as long as broad in ^ , 

 sides ampliated in middle, narrowed in front and behind, the ocular 

 lobes slightly dilated laterally ; upper surface shallowly scrobiculate, 

 the anterior constriction deep and evidently trifoveate, the central 

 furrow broad and shallow in the typical form, but there is a varietal 

 form in which it appears much deeper owing to its margins being 

 elevated into an irregular and angulated cristate ridge ; sides with 

 scattered deep punctuation. Elytra oblongo -ovate, shoulders broadly 

 rounded, sides slightly ampliated, posterior declivity rounded dorsally, 

 apices slightly divaricating in $ ; upper surface with large irregular 

 punctures, the intervals 6, 4 and the apical two-thirds of 2 with large 

 closely set subconical tubercles, those at the top of the declivity 

 being scarcely larger than the others ; interval 2 with a small basal 

 callus, 3 with a larger and oblique callus, 5 with a prominent 

 elongate humeral tubercle ; inflexed margins with large shallow 

 punctures which are more or less irregular. Legs with uniform 

 grey scaling and scattered dark setae ; posterior tarsi with joint 1 

 much longer than 2, anterior pair with the second joint strongly 

 transverse.

Type in the Oxford Museum ; type of mendica in the British 

 Museum. 



A co-type of B. hisignata, Fairm., in the S. African Museum agrees 

 fairly closely with the type of hopei. B. mendica, Pasc, I can only 

 regard as a very dwarfed male of this species. In some aberrant 

 examples which I temporarily attribute to this species the tubercles 

 are much reduced either in size or number. From sulcicollis, Gyl., 

 this insect can only be discriminated with certainty by the tarsal 

 characters mentioned in the Key.
