AMERICAN COLEOPTERA. 55 



broadly incised behind. This species is allied to C. canalieulatus, but 

 the prothorax is more convex, the foveas adjacent to the front angles 

 do not extend to the apical margin and the hind angles are much re- 

 tracted, so that the base is fully one-fourth narrower than the middle 

 of the prothorax, as in C. varidosits^ to which it in other respects 

 has no resemblance. 



C crinitns. — Brownish-black, not shining, thinly clothed above with 

 very long yellowish hairs; prothorax rather flat, very coarsely punctured, 

 sides rounded, subsinuate towards the base, hind angles rather large, elevated, 

 smooth, circumscribed by an impression, inside of the front angles is a fovea 

 extending to the apical margin; elytra flattened, with the usual sculpture and 

 traces of broad longitudinal grooves. Length .5 inch ; 13 mm. 



One specimen, Utah? The mentum is obtusely pointed behind, 

 and not incised- This species is related to C. Knochii, but the larger 

 hind angles of the prothorax, the more broadly rounded sides, which 

 are distinctly creuate. the less convex disc, and ^bove all the lono' 

 hairs distinguish it at first sight. The legs are as in G. Knochii. 



SCAPTOL,EWUS Lee. 

 S. estriatus.— Brown, pubescent, hairs on prothorax, base of elytra and 

 breast longer; elytra rather finely and densely punctured, without any 

 appearance of striae. Length .5.3 inch; 13 mm. 



One immature specimen from Texas. Very different from S. Le- 

 contei Salle ( /emoralix | Lee), by the elytra having no vestige of 

 striae; otherwise it resembles that species, but is smaller, with the 

 prothorax broader and the 3d joint of the antennae more than one- 

 half as long as the 4th. 



In the Mexican S. femnrali^ the elytra are striate, but the protho- 

 rax is still broader and much more rounded on the sides, and the 2d 

 and 3d joints of the antennae are nearly equal, together a little more 

 than one-half as long as the 4th. 



BBACHYPSECTRA, n. g. {Rhipiceridm.) 

 Body elongate, rather flattened, shining, punctured and pubescent; 

 elytra strongly margined, feebly striate; head moderate, front convex, 

 and mouth inflexed ; labrum smaP, mandibles not prominent, palpi 

 small and slender; antennae inserted in triangular excavations, not 

 distant, U-jointed, joints 1—4 subequal, 3d a little longer, 5—10 tri- 

 angular, transverse forming a serrate elongate mass, 11th larger, ap- 

 pendiculate, eyes large, oval, finely granulate ; prothorax transverse, 

 trapezoidal, side margin distinct, hind angles acute subcarinate ; pros- 

 ternum broad, feebly rounded in front, distinctly prolonged behind
