but in its unusually short third and long- fourth antenna! joints, 

 these being virtually equal, and in the absence of any decided sexual 

 modification of the basal portions of the abdomen, although the 

 impression of the fifth segment is well developed. The description 

 is taken as usual from the male, the female being parallel. 



40 B. lilliiiilis 11. sp. — Oblong-elongate, slender, parallel, moderately 

 convex, black, feebly aliifaceons ; pubescence extremely sbort and excessively 

 sparse, stiff, cinereous and completely inconspicuous. Head rather large, 

 transverse, feebly convex, somewhat sparsely and unevenly punctate, the 

 punctures moderate in size and decidedly denser anteriorly ; epistoma rather 

 deeply sinuate in the middle ; upper lobe of eyes large and well developed, 

 nearly circular ; antennje moderate, gradually, strongly incrassate, second 

 joint as long as wide, subequal to the fifth, fully two-thirds as long as tlie 

 third, three to five decreasing rather rapidly in length. Prothorax about two- 

 thirds wider than the head and nearly two-thirds wider than long ; sides very 

 feebly convergent from base to apex, very feebly subangulate before the middle, 

 the sides thence nearly straight to base and apex, the latter broadly, feebly 

 emarginate in circular arc ; base transverse, lateral sinuations distinct ; disk 

 transversely, evenly and very moderately convex, finely and rather sparsely 

 punctate toward the middle where the punctures are separated by about twice 

 their own diameters, thence gradually coarser and denser laterally but not 

 coalescent ; interspaces finely granulato-reticulate. Scutellum well developed. 

 Elytra long, fully four-fifths longer than wide, scarcely visibly wider and two 

 and one-half times longer than the prothorax ; sides parallel and just visibly 

 arcuate ; disk with narrow but rather deeply and abruptly impressed striae, 

 which are ^ery finely and deej^ly punctate, more coarsely so laterally, the 

 punctures generally separated by two or three times their own diameters ; 

 intervals nearly flat, minutely, sparsely punctate, feebly undulated. Abdo- 

 men very finely and sparsely punctate, longitudinally rugulose toward base, 

 polished, the pubescence exceedingly short, recumbent, cinereous and scarcely 

 at all noticeable. Legs moderate, piceous. 



3/aIe. — Anterior tarsi feebly but distinctly dilated, spongy-pubescent be- 

 neath ; intermediate just visibly dilated, narrowly and not very densely 

 spongy-pubescent beneath ; abdomen narrowly and very feebly impressed in 

 the middle toward base, the first segment not more densely j)unctate in the 

 middle. 



Length 4.0 mm. ; width 1.7-1.8 mm.

One of the smallest species of the genus, comparatively isolated 

 in its narrow form and extremely short inconspicuous pubescence. 

 I have seen three specimens.
