Represented by a single female example, hitherto confounded 

 with conjluens, which it resembles somewhat in form and size ; 

 in conjluens the subbasal median pit of the pronotum is extended 

 laterally in a feeble arcuate groove to the lateral fovese, and, in the 

 present form, the head is larger and more sparsely punctate, and 

 the discal stria of the elytra shorter. The last ventral segment 

 is broadly and arcuately lobed at apex, the surface ascending 

 apically and convex.

In this genus the body is narrow, linear and subdepressed as in 

 Euplectus, and the mesosternal side-pieces are divided in the 

 same way into two nearly equal triangular sclerites by fine 

 sutures; but in Euplectus the met-episterna are slightly wider 

 anteriorly, while in the present genus they are very narrow, 

 parallel, linear and entirely covered by the elytra, the anterior 

 pubescent fovese of the metasternum being much smaller and 

 more punctiform. It differs from Euplectus in its more narrowed 

 front, in its 5-jointed antennal club, this beginning really with 

 the seventh joint, and in the type of male sexual form of the 

 seventh ventral segment. As in Euplectus, the middle tibise of the 

 male have a distinct internal uncus at apex, but, unlike that genus, 

 the hind tibiae in the same sex are broadl}^ grooved externally 

 toward tip ; the tarsi are much shorter and thicker in the female 

 than in the male. The under surface of the head is completely 

 devoid of erect capitate sette, but there are four remarkable spini- 

 form appendages arranged in a transverse line anteriorly, one at 

 each apical angle of the mental support, and one at each outer 

 posterior angle of the buccal opening. The first four dorsal seg- 

 ments are exactly equal in length, the fourth not longer as it is in 

 Euplectus. 



The species are all minute, and the one described below is 

 closely allied to integer. 



B. solt)rinus n. sp. — Slender and moderately convex, shining, piceous- 

 black throughout, the head slightly paler ; legs and antennae testaceous ; pu- 

 bescence fine, short, decumbent, and not very abundant. Head very nearly 

 as wide as the prothorax, but slightly wider than long, the eyes moderate in 

 size, convex, at about their own length from the base, the tempora behind 

 them parallel, rounded and as prominent as the eyes ; occiput broadly sinuate,
