as depth of beak at base; antennae inserted just within the basal 

 third of the beak, two basal joints stout, others small, becoming 

 shorter; club large, very loosely jointed, first and second joints 

 subquadrate and equal, third a little narrower and constricted at 

 base, longer than wide and rounded at tip. Prothorax widest at 

 'basal third, barely one-third wider than long, sides strongly 

 arcuate at base, more strongly convergent and straighter towards 

 apex; apex straight, more than three-fourths as wide as base; base 

 broadly and feeblv arcuate ; disk evenly and feebly convex, trans- 

 versely impressed near base, finely, feebly, sparsely and unevenly 

 punctate with traces of median sulcus on impunctate line. Elytra 

 broadly and separately rounded at apex, one-half longer than wide, 

 two-thirds wider than prothorax, sides parallel and nearly straight ; 

 humeri narrowly rounded; disk convex, impressed along suture, 

 feebly and irregularly punctate, rather finely and more coarsely 

 so near suture. Claws armed with a larger tooth.

 coarse and generally rather close; pubescence moderate, short, 

 semierect, whitish. Head almost flat between the eyes; punctuation 

 behind the eyes very minute, but between them close and coarse ; 

 front sulcate; eyes large, convex, and prominent. Beak short, stout, 

 as long as prothorax, over one-third as Wide as the head, evenly 

 arcuate, cylindrical, rugosely punctate, finely above and more coarsely 

 on the sides ; scrobes deep, broad, anterior opening broad, rounded, 

 not narrowed to a point as in rufipennis, beginning at basal third 

 of beak; antennae inserted at basal fourth, 11-jointed, scape and 

 first funicular joint short and stout, second funicular longer than 

 broad, last four becoming shorter and transverse; club three- 

 jointed, as long as the preceding portion of the antennae and three 

 times as broad, first two joints quadrate, third slightly narrower, 

 as long as wide, obtusely rounded at apex. Prothorax widest at 

 basal third, wider than long, sides strongly arcuate at base, more 

 strongly convergent and straighter toward apex; apex straight, 

 three-fourths as wide as base; base broadly, feebly arcuate; disk 

 evenly and feebly convex, transversely impressed near base, 

 coarsely, closely, and unevenly punctate with a smooth impunctate 

 line in front, becoming a sulcus behind the middle. Elytra separa- 

 tely rounded at apex, one-half longer than wide, two-thirds wider 

 than the prothorax, sides nearly straight, humeri narrowly rounded ; 

 disk almost flat, somewhat impressed along suture, coarsely, closely, 

 and unevenly punctate. Claws armed with a large tooth.
