suture at the base, rather finely but distinctly and densely punctate, the 

 punctures separated by but very slightly more than their own diameters ; 

 puVjescence moderate in length. Ahdomen parallel, distinctly narrower than 

 the elytra, rather finely but not very densely punctate toward the apices of 

 the segments, polished and moderately densely punctate beneath. Length 

 5.0-5.7 mm.

The hypomera are broadly, very feebly impressed along the outer 

 edge, the apex about three-fifths as wide as the width at the fissures, 

 the latter rather long, fully as long as the adjacent hypomeral width, 

 and almost completely closed, the prosternal sutures distinct. The 

 mentum is not visibly punctate, shining, coarsely reticulate and 

 distinctly impressed along the base. 



The description of this distinct species is taken from the male, 

 the sixth segment being evenly emarginate in circular arc, the 

 emargination simple, not margined with membrane, and about five 

 times as wide as deep ; the surface at the sides of the emargination 

 bears several very long, erect, interlacing setae. It should.be placed 

 near rubiginosus Er. 



The punctures of the pronotum vary in size, and in some speci- 

 mens are slightly coarser. 



B. assiinilis n. sp. (Fauvel MS.). — Rather slender and convex, black ; 

 elytra piceous ; legs and antennae pale flavate, tlie latter infuscate except 

 toward base ; head and prothorax finely, densely granulate, feebly shining ; 

 abdomen polished, finely, feebly reticulate. Head scarcely perceptibly nar- 

 rower than the prothorax, rather convex, finely, very obsoletely punctate, not 

 tuberculate ; median fovea small, feebly impressed ; antennal prominences 

 small, feeble ; suture fine, distinct, not impressed, arcuate ; epistoma simple ; 

 antennfe rather long, moderately and gradually incrassate ; second joint dis- 

 tinctly longer than the third, four to six decreasing in length, the latter dis- 

 tinctly wider than long, seventh longer, slightly wider than long, eight to ten 

 increasing in length, the latter longer than wide, eleventh nearly twice as long 

 as wide, shorter than the two preceding together ; last three joints together as 

 long as the preceding six. Prothorax slightly but distinctly narrower than the 

 base of the elytra, about one-fourth wider than long ; sides in anterior two- 

 thirds parallel and straight, then convergent and nearly straight to the basal 

 angles, which are obtuse, narrowly rounded, rather distinct but not at all 

 prominent ; lateral angles obtiise, narrowly rounded and rather distinct, apical 

 right and distinctly rounded ; apex almost transversely truncate ; disk very 

 densely and somewhat deeply punctate, the punctures moderate in size, sepa- 

 rated by scarcely their own diameters but slightly sjaarser toward the median 

 impunctate line, which is entire and moderate in width, the median groove 

 being completely obsolete. Elytra nearly as long as wide, two-fifths longer,
