 antennal tubercles ; vertex feebly and shortly carinate ; eyes large ; 

 antennae thick, first joint elongate, cylindrical, second quadrate, third 

 to ninth transverse, fourth and fifth the largest, the following ones 

 slightly decreasing in size, tenth a little smaller and less transverse, 

 eleventh very little larger, quadrate at base, abruptly conical at apex ; 

 prothorax cordate, about as long as broad, sinuate on the sides behind 

 the middle ; lateral foveas large and somewhat lengthened in a fine 

 longitudinal sulcus, median fovea small, median longitudinal sulcus 

 feeble but never wanting, transverse one strong and angular ; elytra 

 a little longer than broad, hardly attenuate at base, with the 

 shoulders oblique, prominent and dentate, dorsal sulcus slender and 

 reaching the median part ; first dorsal segment equal to the follow-

This species resembles very much both B. rugosula and B. 

 7nicrocephala ; it has, like the latter, a transverse sulcus on the 

 front and a longitudinal sulcus on the prothorax like the first, from 

 which it is also differentiated by the smooth teguments.

 tubercles, vertex with a very small and short carina ; antennae robust, 

 first joint elongate, cylindrical, and quadrate, a little transverse, third
