Texas (Austin). 



This species is abundant in June in the valley of the Colorado 

 River of Texas, and although resembling castaneus somewhat, may 

 be easily distinguished by its generally more convex and polished 

 surface, sparser, rather finer and much less rugulose punctuation of 

 the pronotum and more feebly rounded sides of the latter, larger 

 eyes, sparser pubescence, finer and sparser abdominal punctuation 

 and several other characters. The hind wings are well developed. 



6 B. longlllUS Lee— Ann. Lye. Nat. Hist. N. Y., V, p. 147. — Oblong- 

 elongate, parallel, depressed, polished, piceous-black ; legs dark rufous ; 

 pubescence very short, stiff and sparse, pale flavo-cinereous but not at all 

 conspicuous. Head moderately transverse, feebly convex, not very coarsely, 

 densely punctate, the punctures being densely crowded at the edges ; upper 

 lobe of eyes rather larger than usual ; antennae rather long and slender, 

 gradually and feebly incrassate toward apex, third joint very much shorter 

 than the next two together, seventh much longer than wide, eighth scarcely 

 as wide as long. Prothorax nearly two-thirds wider than long, the apex but 

 very slightly narrower than the base ; sides very strongly arcuate, straight 

 near the base, the latter transverse, the lateral sinuations rather feeble but 

 distinct ; basal angles right, rather prominent, not in the least rounded ; apex 

 broadly, rather strongly emarginate in circular arc ; disk widest at about the 

 middle, moderately coarsely punctate, the punctures decidedly sparse toward 

 the middle, denser but not contiguous toward the sides ; basal impressions 

 rather distinct. Scutellum rather small, the polished margin slightly de- 

 pressed. Elytra nearly three times as long as the prothorax, equal in width 

 to the latter, just visibly wider in the female ; sides feebly arcuate, rather 

 obtusely, parabolically rounded at apex; disk coarsely and rather strongly 

 striate, the striae with large deep perforate punctures which are generally 

 separated by a little less than twice their own diameters ; intervals feebly 

 convex, coarsely and sparsely punctured. Abdomen sparsely and coarsely 

 punctate, the pubescence short, flavate, very sparse and not conspicuous. 

 Legs rather long. 



Male — Anterior tarsi quite moderately, the intermediate very feebly dilated ; 

 both pairs finely, densely spongy-pubescent beneath ; abdomen rather broadly, 

 deeply excavated in the middle toward base, the punctures slightly finer and 

 denser along the middle of the first segment, fifth with an oval apical fovea. 



Length 5.8-6.8 mm. ; width 2.2-2.6 mm. 



California; Arizona (Yuma). 



A conspicuously distinct species, easily known by its rather elon- 

 gate parallel depressed form, highly polished integuments, very 

 short and sparse pubescence, and coarse elytral and abdominal 

 punctures. The wings are well developed, extending almost to the 

 apex of the elytra.
