Head nearly impunctate, transversely grooved between the 

 eres, the frontal elevations feebly laised, somewhat trigonate, 

 carina wedge-sliaped, labnim black, palpi slender, tlie last Joint 

 acutely pointed, eyes extremely large, antennae exteuding to the 

 niiddle of the elytra, black, the lower three joints shiuing, the

 one, fourth and following joints elongate; thorax at least twice as 

 broad as long, of the same shape as that of the preeeding species, 

 metallic blue, entirely impunctate; elytra extremely closely and 

 finel}' somewhat riigosely pmutured; below and the legs dark 

 blue, elothed with yellow pubescence, the last abdominal segment 

 of the male with a short lateral oblique incision at each side,

Tliere seem to be all male specimens before me of this 

 species which greatly vary in size; the general shape of the 

 insect is less eonvex and pointed posteriorly than is the easo in 

 B. mefaUica, but the structural characters are the same; the 

 penis is short, the apex strongly produeed and pointed, terminating 

 in two very short points.

 thickencd; thorax about one half broader than long, Ihe sides
