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

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

 own diameters ; pubescence line, very short, rather dense, jiale brownish- 

 cinereous and somewhat conspicuous. Ahihmien distinctly narrower than the 

 elytra and wider than the pi'othorax, very finely and extremely sparsely punc- 

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



Pennsylvania (Allegheny Co.). Dr. Hamilton. 



The hyponicra are about one-half as wide as the distance thence 

 to the coxae and are broadly, rather feebly concave, the sutures ifine 

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

 pioeous-black, slightly paler and testaceous along the apices ; legs and antenn;ie 

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

 notum alutaceous, finely, densely granulose ; elytra and abdomen polished, 

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

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

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

 impressed fovea ; epistoma fiat, more coarsely granulose ; suture fine, not 

 impressed ; antennal jirominences feeble ; antennae 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 ten 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 just visibly sinuate to 

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

 angles rounded, apical slightly obtuse, scarcely perceptibly 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. 

 Eliflni 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 pubescence fine, moderate in length. Ahdnmen 

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

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