21 B. moestUS Melsh. — Proc. Ac. Phila., Ill, p. 65. — Oval, slightly in- 

 flated behind, rather strongly convex, black, strongly shining; pubescence 

 fine, short, pale yellowish-cinereous in color, not dense. Head transverse, 

 feebly convex, very deeply, moderately coarsely and densely punctate, the 

 punctures abruptly finer along the broadly sinuate epistonial apex ; upper 

 lobe of eyes moderate, rounded ; antenna? black, robust, gradually incrassate 

 toward apex, third joint scarcely twice as long as the second, much shorter 

 than the next two, eleventh wider than long, fully as wide as the tenth. 

 Prothorax nearly two-thirds wider than long, widest at two-fiftbs the length 

 from the base ; sides feebly convergent from base to apex, strongly, almost 

 evenly arcuate, straighter or even feebly subsinuate toward base, the latter 

 transverse, the lateral sinuations very strong, the basal angles slightly acute, 

 not in the least rounded and rather prominent ; apex broadly emarginate in 

 circular arc, the angles not at all prominent and very narrowly rounded ; disk 

 very deeply and perforately punctate, the punctures finer and sparse toward 

 the middle, coarser and denser but not at all contiguous or confluent toward 

 the sides, usually abruptly very fine and sparse along the acute marginal 

 bead, especially toward the base. Scutellum moderate, very finely punctate. 

 Elytra with the sides very distinctly arcuate, especially behind the middle 

 where they are distinctly wider than the prothorax, parabolically rounded at 

 apex and about two and one-half times as long as the prothorax ; disk with 

 very fine feebly impressed striae toward the suture, which become rapidly 

 much coarser and more deeply impressed laterally ; stria? finely punctate, 

 more coarsely so laterally ; punctures elongate and posteriorly evanescent, 

 generally separated by twice their own widths ; intervals very finely, some- 

 what sparsely punctured. Abdomen polished, finely, rather sparsely punctate, 

 very sparsely clothed with short inconspicuous pubescence. Legs rather short, 

 the tarsi long. 



Mule. — Anterior tarsi strongly dilated, the basal joint much wider than long 

 and distinctly narrower than the second and third, the latter short, subequal, 

 transversely cresoentiform ; middle tarsi very distinctly dilated, compact, 

 the three basal joints equal in width ; both pairs densely spongy-pubescent 

 beneath ; abdomen not distinctly modified. 



Length 4.7-5.4 mm. ; width 2.1—2.4 mm. 



New Hampshire ; Rhode Island ; Virginia. 



This, the only eastern species of the ordinary type, may be easily 

 identified by its intense black color, shining, rather sparsely punc- 

 tate integuments and prominent basal angles of the prothorax, as 

 well as several other characters. The wings are not well developed, 

 consisting of a long slender hyaline fillet, nearly one-half longer 

 than the prothorax and three-fifths as long as the elytra. 



22 B. gregalis n. sp. — Oblong-oval, moderately convex, black ; antennae 

 piceous-black ; legs dark rufo-piceous ; integuments polished ; pubescence fine, 

 rather short and sparse, pale fulvo-ciuereous and not conspicuous. Head
