as the elytra, with the antennae inserted distinctly behind the mid- 

 dle ; antenna? slender, the second funicular joint fully as long as the 

 next two in the female, slightly shorter in the male. Prothorax 

 nearly as long as wide, eventy rounded at the sides, feebly narrowed 

 but scarcely at all constricted toward apex. Elytra at base one-half 

 wider than the prothorax, a little more than three times as long, 

 parallel in basal half, the sides broadly, feebly but distinctly con- 

 stricted before the apex. Length 1.1-2.2 mm. ; width 0.7-1.0 mm. 

 Kansas, Colorado and Montana. The tarsal claws in this distinct 

 and easily recognizable species are unusually long and divergent 

 but connate at base. 



15 S. sparsus n. sp. — Oblong-oval, convex, deep black througbout, tbe 

 vestiture of tbe upper surface consisting of small elongate-oval whitish scales, 

 uniform throughout and very sparsely scattered over the elytra, the striae in- 

 dicated by partings which are wider than the grooves, rather denser, and 

 wider beneath on tbe sterna and their side-pieces. Head subglabrous, aluta- 

 ceous, finely but strongly reticulate ; transverse constriction well marked, fine ; 

 beak in the male rather long, evenly cylindrical and somewhat thick through- 

 out, feebly, evenly arcuate, sparsely but strongly punctate and subglabrous 

 in apical half, finely and sparsely squamulose and more opaque toward base 

 with the two fasciculate basal tufts small, distinctly longer than the head and 

 prothorax and one-half as long as the elytra ; antenna? inserted at the middle, 

 the second funicular joint subequal to the next two. Prothorax slightly wider 

 than long, the sides feebly convergent, broadly, evenly arcuate nearly to the 

 apex, the subapical constriction not large but distinct ; apex three-fourths as 

 wide as the base ; disk not very coarsely but deeply, closely and evenly punc- 

 tate, the punctures not much obscured by tbe vestiture. Elytra at base one- 

 half wider than the prothorax, three times as long, fully one-half longer than 

 wide, parallel and nearly straight at the sides in basal half, then gradually 

 ogival, not constricted before the apex ; stria? fine, deep, consisting of narrow 

 approximate linear punctures near the sides. Tarsal claws rather long, stout, 

 pointed, distinctly divergent but completely connate at base. Length 2.5 

 mm. ; width 1.1 mm. 



Colorado. 



The single specimen represents a species allied to sordidus and 

 griseus, but differs in the small, widely-scattered scales and black 

 legs. From the male of sordidus it differs in its much longer, non- 

 tapering, sparsely squamulose beak, with the antennae inserted at 

 the middle. The male of griseus I have not at hand, but the female 

 differs from the type of sparsus in its very much larger and more 

 elongate prothorax.
