Male : Black, not very shiny, antennas black, but occasionally 

 flavescent ; clypeus of the same shape as in the preceding species, 

 but much more deeply incised in front, and with the anterior margin 

 more reflexed, the head is sparsely pubescent, the pubescence being 

 flavous, the ocular canthus is also pubescent ; prothorax ampliate 

 rounded laterally in the anterior part only, more parallel behind, and 

 less broadly rounded at the base which is only very slightly sinuate 

 above the scutellum, there is often a strong sub-vertical depression 

 in the anterior part of the disk, and the anterior margin bears a 

 distinct median tubercle, but this depression does either not exist in 

 small developed examples, or is hardly noticeable, but the tubercle 

 is always conspicuous, the whole disk is covered with very closely 

 set and very briefly setigerous cicatricose scabrose punctures which 

 are wider on the sides than in the median part ; scutellum closely 

 punctate ; elytra more attenuate behind than in B. sanguinipes, and 

 having also two discoidal costules which disappear before reaching 

 the apical callus in large examples, but not in the small ones, the 

 surface is covered with a network of cicatricose punctures, and in 

 well-preserved examples are seen rows of moderately remote, short, 

 light fulvous bristly hairs. 



This species varies much in size. As I have already stated, it is in 

 male examples having attained a great development that the sub- 

 vertical or sloping impression in the anterior part of the prothorax is 

 to be found. But I have ascertained by my examination of the 

 genital organs of the $ , that B. armata, Boh., of which I saw
