This is almost identical in appearance with T. fryanns 

 Gorh., an East African species of rather wide distribntion. 

 It is a little more strongly pnnctured above, the shoulders 

 are rather less rounded, and the lower surface, with the 

 epipleurae of the etytra, paler in colour. The male is 

 easily distinguished by the absence of the three pale mem-

 ventral segments, and by the very strong spine at the inner 

 edge of the middle tibia.

 Pedes graciles, femoribus baud valde clavatis. Antennae parum

Type, B. perotieli, sp. n. 



This new genus is necessary for a nondescript Indian 

 insect remarkable amongst the Eumorphini for its short 

 rotund form. It is in some respects a hnk between the 

 Oriental genera and the Ethiopian Trycherus and Haplo- 

 scelis, but its very short, compact shape, and especially the
