TRIBE VII. ERIRHININI. 219 



condensed on sides of thorax and base of third interval. Beak thick, short, 

 distinctly curved, granulose and punctate; of female, one-half as long as 

 elytra, smoother and more shining. Thorax slightly wider than long, 

 sides broadly and feebly curved, converging and nearly straight near 

 apex; punctures of disc coarse and deep, confluent in threes and fours to 

 form oblique sinuous lines. Elytra at base one-half wider than thorax, 

 three-fifths longer than wide, sides nearly straight and parallel to beyond 

 middle, then rounded to apex; strife rather fine, deeper near suture; in- 

 tervals slightly rugose and bearing short, suberect setse. Length 1.7 2 mm. 



Described from North Carolina. Ranges from District of 

 Columbia to Kansas and Texas. Easily known by its small size 

 and the coarse, deep, peculiar sculpture of thorax. LeCoute had 

 specimens labelled as cornicnlatus Fahr. 



305 (10,932). SMICRONYX ATRATUS Dietz, 1894, 153. 



Very close to tychoides. Differs in characters given in key. Elytra 

 never reddish. Beak regularly curved. Second joint of funicle scarcely 

 longer than third. Thorax more convex, with sides more strongly rounded 

 from base to apex. Length 3 mm. 



Known from the District of Columbia and Texas. 



306 (10,937). SMICRONYX N EBULOSUS Dietz, 1894, 157. 



Oval, robust. Piceous, shining, antenna?, legs and apical half of beak 

 reddish-brown; above rather densely clothed with pale yellowish and 

 grayish-white oval scales, mottled with ill-defined areas of a slightly 

 darker shade; beneath more sparsely with smaller dirty gray scales. Beak 

 of male rather stout, as long as thorax, distinctly curved, tapering, gla- 

 brous and almost smooth in front of antennse, sparsely scaly and finely 

 punctate behind; of female one-third longer, more slender, cylindrical, 

 glabrous almost throughout, densely punctured and scaly at base. Second 

 joint of funicle nearly twice as long as third. Thorax wider than long, 

 widest at middle, sides strongly rounded, distinctly constricted near apex, 

 hind angles rounded; disc densely punctate, the punctures shallow, 

 elongate-oval. Base of elytra two-fifths wider than that of thorax, sides 

 parallel to middle then evenly curved to apex, strise not deeply impressed, 

 their punctures small, remote; intervals with long, inclined, whitish, 

 hair-like setse, the base of the third with a short white line. Tarsi slen- 

 der, the fourth joint twice as long as third. Length 3 3.5 mm. 



Described from Indiana from specimens in the Horn collec- 

 tion without definite locality ; also from District of Columbia 

 and New Jersey. Edgebrook and Bloomington, 111.; August 27- 

 28. The white scales of elytra in some specimens form conspicu- 

 ous wavy transverse bands. Either this species or the next, per- 

 haps both, as they are closely allied, was described by Casey 

 (1892, 400) as flaricans Lee., the locality being given as Texas, 

 Dakota and Indiana. An examination of the type of flavicu-nt.
