diverging backwards ; clypeal suture strongly impressed and 

 connecting frontal impressions in front ; clypeus declivous to 

 lal)rum ; eyes convex, set lightly in orbit at base. Prothorax 

 shortly subcordate (2-8 x 3-5 mm.), convex, very lightly declivous 

 posteriorly, not wider across base than apex ; disc transversely 

 striolate ; sides rounded, more shortly and decidedly so to anterior 

 angles, lightly and evenly so to base ; anterior margin hardly 

 emarginate ; base lightly rounded ; anterior angles rounded, 

 hardly advanced ; basal angles rounded, not marked ; lateral 

 l)order thick, ending at basal angle ; median line well marked, 

 linear ; two lateral basal impressions on each side ; the interior 

 short, narrow, linear at bottom, attaining base ; the external 

 foveiform, placed near the basal angle ; space between inner basal 

 impressions depressed below disc, convex ; posterior marginal 

 puncture at basal angle. Elytra a little wider than prothorax, 

 oval (7x4 mm.), truncate on base with shoulders rounded, 

 convex ; sides lightly rounded ; apical curve widely but decidedly 

 sinuate ; strite subcrenulate ; four inner stripe entire, strongly 

 impressed, fifth entire, very lightl}'' impressed, sixth and seventh 

 obsolete, except towards the apical extremity, eighth strongly 

 impressed; four inner and ninth interstices strongly convex, 

 ninth punctate as usual in genus ; lateral border finely reflexed, 

 marginal channel narrow. Prosternum bordered on base. 

 Ventral segments finely and closely rugulose-punctulate. 



Length 12, breadth 4 mm.

This species can only be compared with B. angustulus, MacL, 

 but I have been able to ascei'tain by comparison with the type of 

 Ji. angustulus that it is distinct. Beyond the larger and heavier 

 form of the present species I cannot now suggest the actual 

 differences between them. The narrow convex facies of these 

 two species separate them decidedly from all the others of the 

 genus I have seen.
