where the sculpture becomes obsolete; base broadly arcuato-truncate, the angles 

 rounded, the tempora long, becoming straight and parallel to the eyes, which 

 are small, very convex and prominent ; antennae about as long as the head and 

 prothorax, slender, the three outer joints thicker. Prothorax convex, quite 

 distinctly narrower than the head, not quite as long as wide, rather broadly 

 rounded at apical third, the sides thence convergent and feebly sinuate to the 

 base, which is narrowly margined and much narrower than tlie disk; punctures 

 fine and very dense. Elytra three-fourths longer than wide, but slightly more 

 than twice as wide as the prothorax; sides parallel and arcuate; apex obtusely 

 rounded; humeri moderately exposed at base, rounded; scutellar impression 

 obsolete, the omoplates very feeble; punctures somewhat coarse and sparse. 

 Abdomen alutaceous, finely, densely punctate, pubescent, blackish with the 

 apex pale. Zc^s slender, the femora somewhat stout. Length 2.0-2.5 mm. ; 

 width 0.65-0.8 mm. 



Colorado (Greeley); Iowa. 



The four specimens before me vary greatl}' in size as is usual 

 in this genus, and the description is drawn from the male, this sex 

 having the anterior tibiae ver3" strong!}' arcuate and pubescent 

 within, the intermediate more apically and less strongly arcuate, 

 the anterior trochanters feebly and obtusely prominent behind , 

 the intermediate unmodified, the fifth ventral moderate in length 

 and evenly rounded behind, unmodified or only sliglitl}' flattened 

 on the disk. The female has the prothorax smaller, and the el^'tra 

 shorter and relatively broader, and, in one specimen, completely 

 infuscate except toward the humeri and sides before the middle. 



9. S. mollis n. sp. — Slightly stout, convex, pale brownish-testaceous 

 throughout, the antennaj blackish at apex, the elytral suture not darker, shin- 

 ing, the head, pronotum and abdomen alutaceous ; pubescence not dense, 

 rather short and coarse, the coarser hairs of the eljtra inclined. Head slightly 

 transverse, finely, very densely punctate, with a narrow- impunctate line 

 except toward base, where the punctures become feeble; basal angles some- 

 what narrowly rounded; tempora long, parallel and feebly arcuate; eyes 

 small, very convex and prominent; antennse rather longer than the head and 

 prothorax, slender, the clul) abrupt and distinct. Prothorax small, much nar- 

 rower than the head, not quite as long as wide, evenly and circularly 

 rounded anteriorly, the sides thence convergent and sinuate to the base which 

 is very widely and stronglj- margined, slightly dilated at the sides and dis- 

 tinctly narrower than the disk ; surface finely, densely punctate. Elytra 

 three-fourths longer than wide, distinctly more than twice as wide as the pro- 

 thorax, parallel and broadly arcuate at the sides, evenly and not very 

 broadly rounded at apex; humeri obtuse and moderately expo.sed; post-scu- 

 tellar impression distinct at each side of the suture; omoplates large, very 

 feeble; punctures moderately coarse and sparse. Abdomen minutely and 

 densely punctured, the legs rather short and stout. Length 2.2 mm.; width 

 0.75 mm.
