towards the sides ; elytra elongate, subparallel in their basal half, with rows of very coarse, deep, not 
very closely placed, foveate punctures, which towards the sides and apex are placed in shallow stria, the 
interstices con vex towards the sides and at the apex, almost flat on the disc, thickly, somewhat coarsely 
punctate ; beneath shining, very coarsely, rather closely punctate, the flanks of the prothorax coarsely, 
longitudinally wrinkled. 
Length 7%, breadth 33 millim. (9.) 
Hab. Mexico, Temax in North Yucatan (Gawmer). 
One example. Allied to B. fortis, Lec., but more shining, the thorax more rounded 
at the sides and more coarsely, confluently punctate (in this respect resembling 
B. dilatatus), the elytra with series of coarse, deep, foveate punctures. The serial 
punctures of the elytra are coarser and deeper than in any other species of th genus 
known to me.
