more slender, and much more feebly incrassate, with joints six and 

 seven distinctly longer than wide, and eight fully as long as wide, 

 nine and ten much less abruptly longer than eight ; in the present 

 species the eighth joint is nearly one-half wider than long. The 

 description is taken from the only specimen which I have seen, and 

 this is unfortunately the female, but the above comparison has been 

 made with the same sex of fumatus. 



The hypomera are flat, rather wide, the apical width fully one- 

 . half that at the fissures, the latter rather long but slightly shorter 

 than the hypomeral width in continuation of them, and are almost 

 completely closed ; the prosternal sutures are very distinct, being 

 defined by a fine elevated line. The mentum is shining, coarsely 

 reticulate, finely, deeply impressed along the base and unusually 

 coarsely, deeply but very sparsely punctate. 



B. gravidus n. sp. — Moderately robust, rather convex, piceous ; elytra 

 bright rufous, feebly clouded with piceous toward base, and slightly along the 

 suture ; abdomen above and beneath dark rufo-testaceous, the apices of the 

 segments clouded with piceous ; head finely reticulate, feebly shining ; pro- 

 notum distinctly reticulate, rather strongly shining, the reticulation obsolete 

 posteriorly toward the sides, the surface becoming polished ; abdomen polished, 

 finely, very feebly and subobsoletely reticulate. Head rather distinctly nar- 

 rower than the prothorax, feebly convex, finely, sparsely and not very dis- 

 tinctly punctate, not tumid in the middle, the median puncture small, rounded, 

 feebly impressed, not surrounded by a polished area ; antennal tuberculatious 

 large, short, moderately prominent, polished toward apex ; suture fine, feebly 

 arcuate, not impressed ; apical angles of the epistoma distinctly tuberculate ; 

 eyes large, more convex behind ; antennje rather long, the last five joints 

 gradually, evenly and moderately incrassate ; second joint scarcely perceptibly 

 longer, although distinctly more robust than the third, sixth slightly wider 

 than long, eighth about one-third wider than long, ninth and tenth longer, the 

 latter sliglitly wider than long, eleventh one-half longer than wide. Prothorax 

 rather distinctly narrower than the base of the elytra, nearly one-third wider 

 than long ; sides from apical fourth to just behind the middle parallel and 

 straight, then convergent and just visibly arcuate to the basal angles, which 

 are very obtuse, rather broadly rounded altlioiigh somewhat definable ; lateral 

 angl<!S obtuse, very broadly rounded and not distinct; sides in apical fourth 

 convergent and strongly arcuate, the angles at the apex being slightly obtuse 

 and scarcely at all rounded; apex transversely truncate; base just visibly 

 arcuate ; disk convex, finely, sparsely and unevenly punctate, the punctures 

 distinct but not very deep, the median groove rather fine but deeply impressed 

 and distinct. Elytra not quite as long as wide, together broadly, angularly 

 emarginate at apex, one-fourth wider and one-third longer than the protlu)rax ; 

 sides feebly divergent ; disk flattened but not distinctly impressed on the
