devoid of the apical beaded edge ; the two species may, however, 

 be considered congeaeric for the present and can l)e distin- 

 guished as follows : — 



Large, the elytra broad, finely and sparsely punctate toward base; color black, 

 the prothorax dark red-brown 1. priliiiosus 



Small and narrow, pale testaceous throughout, the elytra strongly and densely 

 punctate toward base 2. luteollis 



These species represent one of the most distinct generic types 

 of the subfamih', because of the finely faceted eyes. 



1. S. pruiiiosilS n. sp. — Eather broad and depressed, black throughout, 

 the legs, antennae and prothorax dark rufo-testaceous ; integuments alutaceous, 

 densely and verj' minutely punctulate throughout, also visibly punctate, the 

 larger punctures not bearing longer hairs; pubescence \'ery minute, extremely 

 dense and decumbent, giving a densely pruinose effect. Read transverse, 

 convex, finelj', rather sparsely punctate ; eyes separated by one-half more than 

 their own width; tempora rounded, one-half as long as the eyes and a little 

 less prominent; antenna? two-fifths as long as the hody, gradually and dis- 

 tinctly incrassate, the third joint slender and longer tlmn the fourth, tenth as 

 long as wide, eleventh conoidal, obliquely pointed, not as long as the two pre- 

 ceding. Prothorax as wide as the head, slightly wider than long, prominent 

 and subtuberculate at the sides at apical two-fifths, the sides thence strongly 

 oblique and straight to the apex which is transversely truncate and two-thirds 

 as wide as the base, feebly convergent toward base; disk feebly convex, 

 finely, sparsely punctate, very obsoletely, transversely impressed near the base. 

 Scutellum trapezoidal, wider than long, the angles somewhat prominent. 

 Elytra broad, two-thirds longer than wide, twice as wide as the prothorax, 

 parallel and feebl}' arcuate at the sides, broadlj- rounded at apex; humeri 

 rounded, rather widely- exposed at base; disk somewhat flat, the omoplates 

 feeble; punctures fine and sparse toward base, becoming gradually subobsolete 

 behind the middle. Ahdomen alutaceous, finely, densely pubescent, with a 

 few small and scattered punctures in the middle near the base. Legs mode- 

 rately long, slender. Length 2.8 mm. ; width 1.0 mm. 



Arizona (Williams). 



This species is relatively large for the present subfamily, and 

 greatly resembles an Anthicus, to such an extent in fact that it 

 was sent to me as a representative of that genus. The sex of the 

 unique individual is not determinable. 



2. S. luteolu$$ n. sp. — Narrow and somewhat convex, pale rufo-testa- 

 ceous throughout, the elytra more flavate and the hind femora slightly 

 brownish; integuments alutaceous, the minute punctules bearing the extremely 

 fine decumbent pubescence not visible, being entirely occupied by the bases of 

 the hairs; larger punctures rather dense and distinct. i/rarZ transverse, con- 

 vex, finely, somewhat sparsely punctate toward base; eyes prominent, sepa-
