very coarse and deep ; dividing line of the epimera very fine and feeble. Legs 

 long, slender, the hind tarsi three-fourths as long as the tibiae, the basal joint 

 as long as the next three. Length 2-5 mm. ; widtli 1.4 mm. 



Rhode Island (Boston Neck) ; "Virginia ; Indiana. 



The type is a male, having the fifth ventral plate very feebly 

 bisinuate toward the middle, the sixth produced in a slender, 

 gradually narrowed, acutely rounded process, longer than wide, 

 flanked by broadly rounded shallow eraarginations which are larger 

 and more feeble than in concolor. The species is also distinguish- 

 able from concolor by Its saialler size, less obese form, relatively larger 

 elytra with broadly and completely obliterated basal stria, and by the 

 form of the lateral margin of the prothorax, which is more abruptly 

 though broadly bent downward posteriorly. Four specimens. 



B. speculifer n. sp. — Rather narrowly oval, highly polished, black ; 

 legs, antennje, tips of the elytra and abdominal apex paler, testaceous ; integu- 

 ments subglabrous and subimpunctate. Head small, the eyes large, separated 

 by more than their own width ; antennae slender, scarcely as long as the head 

 and prothorax, joints three to seven subequal in length, eighth shorter, third 

 four times as long as wide, seventh and eightli thicker, club almost symmetri- 

 cal, joints nine and ten nearly equal, obconical, strongly compressed as usual. 

 Prothorax short, two-thirds wider than long, strongly declivous anteriorly, the 

 apex not visible from above but scarcely more than one-third as wide as the 

 base ; basal lobe strong but evenly rounded ; angles rather acute. Scutellum 

 completely wanting. Elytra rather longer than wide, twice as long as the 

 prothorax, very broadly, feebly rounded at the sides biit somewhat wider at 

 basal fourth than at base ; sutural and lateral strise deep, the latter slightly 

 punctate ; basal and apical striae entire ; apex transversely truncate, the 

 external angles broadly rounded. Mes-epimera rather short, barely extend- 

 ing two-thirds to the coxae ; met-episterna narrow, subparallel, the suture 

 coarse deep and unevenly punctate ; epimera distinct. Legs slender, the pos- 

 terior tarsi very slender but quite distinctly shorter than the tibiae. Length 

 1.6 mm. ; width 0.9 mm. 



Iowa (Keokuk). 



This species perhaps resembles apicalis more than any other, but 

 may be separated by its longer antennal joints and much more 

 elongate mes-epimera, as well as by the more broadly oval form of 

 the body and broader, less strongly rounded median thoracic lobe. 

 Two precisely similar specimens. 



B. apicalis Lee— Proc. Ac. Nat. Sci., Phila., 1860, p. 323. 



Black, polished, subimpunctate and subglabrous ; elytra rufescent 

 along the suture and apex; legs and abdomen rufous. Antennae
