284 (10,922). SMICROXYX GIBBIROSTRIS Casey, 1892, 407. 



Oval, robust, convex. Black, elytra pale reddish-brown, narrowly 

 blackish along the suture; legs, except base of femora, reddish-brown; 

 upper surface sparsely and unevenly clothed with yellowish scales and 

 fine scale-like hairs, the former more dense on the sides and base of 

 thorax and in spots and short bars on elytra; under surface rather densely 

 scaly. Beak of male stout, slightly longer than head and thorax, feebly 

 curved, densely punctate. Thorax one-third wider than long, the sides 

 broadly rounded, convergent toward apex, disc densely and finely punctate. 

 Elytra at base one-third wider than thorax, one-fourth longer than wide, 

 sides parallel to behind the middle, thence converging to tips; stria? deep, 

 distinct. Length 2 mm. 



Known from Delaware and District of Columbia. Differs 

 from sculpticollis, our other species with the elytra of similar 

 color, in its larger, more densely sculptured thorax and much 

 shorter elytra.
