cent, pronotal punctuation, by the unusually coarse abdominal punc- 

 tures and, for the present group, unusually feebly dilated anterior 

 tarsi of the male, the latter character allying it with longulus and 

 validus. I have not been able to examine the wings as the type is 

 unique. 



17 B. fllliginosiIS n. sp. — Oblong-elongate, parallel, strongly convex, 

 rather dull, piceous-black ; legs dark rufo-forruginous ; pubescence short, 

 fine, dark subpiceous, inconspicuous. Head feebly convex, rather finely 

 punctate, densely so laterally but rather more coarsely and decidedly more 

 sparsely along the middle throughout the length ; upper lobe of eyes moder- 

 ate, rounded ; antenn;« moderate, gradually and distinctly incrassate through 

 the last four joints, third much shorter than the next two. Prothorax rather 

 less than one-half wider than long, slightly narrower at apex than at base, 

 the sides very evenly and moderately arcuate throughout ; base transve-rse, 

 the siuuations rather strong ; basal angles right, not at all rounded ; apex 

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

 rather finely punctured, a little more sparsely so toward the middle, the 

 punctures toward the sides having but slight tendency to coalesce, although 

 extremely dense. Scutellum moderate, densely punctate, a longitudinal line 

 and the apex broadly polished and impunctate. Elytra scarcely wider, and 

 fully two and one-half times longer tlian the prothorax, evenly roamlcd at 

 apex ; sides feebly arcuate ; disk very finely striate, the stria; very feebly 

 impressed but a little more distinctly so laterally, very finely but deeply 

 punctured, the punctures very unevenly but in general remotely spaced, 

 separated by from two to four times their own diameters ; intervals nearly 

 flat, finely and rather sparsely punctate. Abdomen somewhat dull, finely and 

 not very sparsely punctate, the pubescence very short, rather fine, somewhat 

 abundant, pale flavo-cinereous and distinct. L-^ijs moderate in length, rather 

 robust. 



Male. — Anterior tarsi very strongly dilated, the second joint not much longer 

 than the third, the latter deeply emai'ginate above at apex : intermediate dis- 

 tinctly dilated, more elongate, but scarcely more than two-thirds as wide as 

 the anterior ; both pairs densely spongiose beneath ; abdomen very broadly, 

 feebly impressed in the middle toward base, with the punctures slightly but 

 indefinitely denser. 



Length 6.0 mm. ; width 2. .5 mm. 



California (Sacramento). 



The singular and unusual median impunctate line of the scutellum 

 may possibly be accidental in the only known specimen. 



This species is quite distinct and may be distinguished by its dull 

 lustre, ver}' feebly impressed strite which are very remotely punc- 

 tured, by the short pubescence especially of tin- abdomen, and otlicr
