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

 be considered congeneric for the present and can be distin- 

 guished as follows : — 



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

 the prothorax dark red-brown 1. priliiio»>(ll$« 



Small and narro\\-, pale testaceous throughout, the elytra strongly and densely 

 punctate toward base 2. liiteolus 



These species represent one of the most distinct generic types 

 of the subfamily, because of the finely faceted eyes. 



1. S. pruiiiosiis n. sp. — Rather broad and depressed, black thrpughout, 

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

 densely and very minutely punctulate throughout, also visibly punctate, the 

 larger punctures not bearing longer hairs; pubescence very minute, extremely 

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

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

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

 less prominent; antenna^ two-fifths as long as the body, gradually and dis- 

 tinctly incrassate, the third joint slender and longer than 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 subtubei'culate 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 Avide, twice as wide ds the prothorax, 

 parallel and feebly arcuate at the sides, broadly 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. Abdomen alutaceous, finely, densely pubescent, with a 

 few small and scattered jiunctures 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 

 greatl}^ 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. luteolus 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 decirmbeut pubescence not visible, being entirely occupied by the bases of 

 the hairs; larger punctures rather dense and distinct. Head transvcvse, con- 

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