Length, 6.7-7.3 mm ; width, 2.7-3.3 mm. Derm black, densely 

 clothed with striated brown scales, which in general have a dull 

 coppery tinge, paler on head, rostrum, and vertex of head, and some- 

 times greenish toward apex of rostrum above ; elytra with or without 

 a few blackish mottlings. Prothorax of male inflated, the sides 

 strongly rounded. 



Rostrum stout, somewhat shorter than prothorax, above densely 

 scaly, a little wider and more nearly flat than in alternatus, the 

 rather feeble scale-covered median carina not reaching beyond apical 

 third ; front flat to broadly and feebly concave ; first and second 

 funicular segments elongate and subequal, other segments longer 

 than wide except fifth and sixth, which are usually about as wide 

 as long. Prothorax a little wider than long in both sexes, about 

 seven-eighths (J*) and five-sevenths ($) as wide as elytra; pronotum 

 with a shallow median sulcus, which is wider and deeper apically, 

 usually interrupted at middle and sometimes obsolescent basally, the 

 general surface with small, scale-covered, setigerous tubercles. Elytra 

 distinctly narrower in J*, the sides parallel (J^) or slightly rounded 

 and convergent (5) from behind the distinct humeral sinuation to 

 apical third, alternate intervals costate and with a crowded row 

 (double in places) of long setae; even intervals usually nonsetose, or 

 second and fourth with a few at base and apex, the sixth occasionally 

 with a widely spaced row, the serial scales variable in shape, but at 

 least some of them oblong or ovate (not all subcircular). Fifth 

 sternite of male with a feeble submedian impression. Ventral edge 

 of tibiae with a few erect denticulations, strongest on front pair, 

 feeblest on hind pair.
