much broader club than in any of the allied species and the third 

 joint is more elongate. 



20 B. elongattlS n. sp. — Elongate-oval, strongly convex, black ; legs 

 piceous-black ; integuments dull ; pubescence rather short, sparse, dark 

 fnlvo-ciiiereous and inconspicuous. Head transverse, feebly convex, rather 

 finely, deeply, nearly evenly and very densely punctate; epistoma broadly 

 and unusually feebly sinuate; upper lobe of eyes small; antenme rather 

 robust, very evenly, gradually but moderately incrassate from the seventh 

 joint, third short, scarcely twice as long as the second and much shorter than 

 the next two together, eleventh rather longer than wide, narrowly truncate at 

 apex and scarcely visibly narrower than the tenth. Prothorax rather elongate, 

 about two-fifths wider than long, very feebly narrowed from base to apex, the 

 sides almost evenly and rather feebly arcuate ; base transverse, the sinuations 

 moderate ; basal angles rather more than right, not at all rounded ; apex 

 feebly emarginate in circular arc ; disk evenly convex, very densely punctate, 

 the punctures fine toward the middle where they are generally separated by 

 scarcely their own diameters, a little coarser, very dense and with a slight 

 tendency to longitudinal coalescence laterally. Scutellum moderate, densely 

 punctate. Elytra, just behind the middle, slightly wider than the prothorax, 

 about two and two-thirds times as long as the latter, parabolically and some- 

 what broadly rounded behind ; sides distinctly but broadly arcuate ; disk 

 very finely, feebly striate, the sutural and outer striae very slightly more 

 distinct, very finely feebly and approximately punctate ; intervals nearly 

 fiat, finely and sparsely punctate. Abdomen shining, rather rugulose, finely, 

 sparsely punctate, the pubescence short, fine, sparse, rather dark and not 

 conspicuous. Legs rather long and slender. 



Male. — Anterior tarsi very strongly dilated, the second joint much longer 

 than the third ; intermediate less strongly dilated ; abdomen broadly and 

 feebly impressed in the middle toward base ; the punctures crowded and dense 

 only in a small oval area in the anterior half of the basal segment. 



Length 5.6 mm. ; width 2.2 mm. 



California (Lake Co.). 



The two specimens before me are males, and from their narrow- 

 slender form it is probable that the female will prove to be robust 

 as in rvfipea; they indicate a species rather closely allied to rufipes, 

 but differing conspicuously in the nature of the abdominal pubes- 

 cence, also in the somewhat larger size and longer piceous-black 

 legs. The antennae are nearly as in rufipes, but are more gradually 

 incrassate, the three outer joints not being at all abruptly wider as 

 is the case in that species. 



I have not been able to inspect the wings, but they are undoubt- 

 edly rudimentary.
