distinctly and densely punctate, the punctures rather fine, about twice as 

 dense as those of the pronotum, and separated by slightly more than their 

 own diameters ; pubescence fine, very short, rather dense, pale brownish- 

 cinereous and somewhat conspicuous. Abdomen distinctly narrower than the 

 elytra and wider than the prothorax, very finely and extremely sparsely punc- 

 tate, somewhat coarsely and moderately densely so beneath. Length 3.5 mm. 



Pennsylvania (Allegheny Co.). Dr. Hamilton. 



The hypomera ai-e about one-half as wide as the distance thence 

 to the coxfe and are broadly, rather feebly concave, the sutures fine 

 and distinct, the coxal fissures rather long and extremely widely 

 open. The mentum is rather shining, broadly, feebly concave, the 

 apex being broadly feebly emarginate. 



This species belongs near annularis, but differs in its more shin- 

 ing, more sparsely and distinctly punctate, and decidedly wider and 

 more transverse prothorax, the hind angles being more prominent, 

 and in its larger, longer and wider elytra. 



B. adiistus n. sp. (Fauvel MS.) — Slender, subparallel, black ; elytra 

 piceous-black, slightly paler and testaceous along the apices ; legs and antennae 

 dark rufo-testaceous, the femora slightly clouded toward base ; head and pro- 

 notum alutaceous, finely, densely grauulose ; elytra and abdomen polislied, 

 the latter coarsely reticulate, the lines very fine, the reticulations not finer 

 toward apex. Head very slightly narrower than the prothorax ; eyes mode- 

 rate ; surface feebly convex, not tuberculate, the vertex with a small median 

 impressed fovea; epistoma flat, more coarsely grauulose; suture fine, not 

 impressed ; antennal prominences feeble ; antenufe rather short and robust, 

 but feebly compressed ; second joint more robust and fully one-half longer 

 than the third, four to six decreasing in length, seven to.teu rather abruptly 

 wider, transverse, the latter two-thirds wider than long, eleventh ovoidal, 

 slightly longer than wide. Prothorax very slightly narrower than the base of 

 the elytra, scarcely one-fourth wider than long ; sides in anterior three-fifths 

 parallel and distinctly arcuate, thence convergent and j ust visibly sinuate to 

 the basal angles, which are obtuse but not rounded, and not prominent ; lateral 

 angles rounded, apical slightly obtuse, scarcely percej^tibly rounded; apex 

 feebly arcuate, two-fifths wider than the base, the latter subtruncate ; disk 

 rather convex, not very coarsely but rather sparsely and very indistinctly 

 punctate, the punctures feebly impressed ; median groove impressed, distinct. 

 Elytra quadrate, one-third wider and nearly one-half longer than the protho- 

 rax, scarcely perceptibly wider toward apex; sides very feebly arcuate; disk 

 rather convex, not impressed in the middle at base, rather coarsely, feebly and 

 not very densely punctate, the pubescfnce fine, moderate in length. Abdomen 

 slightly narrower than the elytra and wider than the prothorax, very finely, 

 sparsely punctate, more densely so beneath. Length 3.0 mm.
