New Neotropical Coleoptera

This new species appears at first sight as nearer to 
Canthochilum Chap, than to Bdelyrus Har. but the structure 
Of the elytra ranges it decidedly in this last genus. B. bow- 
ditchi n. sp. is quite different from B. seminudus Bates 
(from Costa Rica and Ecuador) by the puncturation, the 
shagreened upper surface and the quadridentate clypeus. 
B. lagopus Har. from Brazil, the genotype, is unknown to me 
but nothing in its description differentiates it from B. sem- 
inudus, which, by the way, Bates placed in Aphengium.
