then gradually acutely ogival ; strife indicated by narrow partings of the ves- 

 titure. Length 1.4-1.7 mm. ; width 0.6-0.7 mm. 



Arizona. 



The five specimens in my cabinet display scarcely any variation. 

 This is one of the most minute species of the genus, and will be 

 easily known by the characters given. 



13 S. spurcus n. sp. — Rather broadly oblong-oval, moderately convex, 

 black, the beak piceous ; legs rufous, blackish near the base, the tarsi black- 

 ish ; vestiture of the upper surface consisting of extremely dense, widely 

 imbricated, pale ochreous-yellow scales, rather small in size, uniformly dense 

 throughout the pronotum, scarcely visibly uneven in coloration on the elytra, 

 nearly similar beneath and equally dense; recurved setae stout, rather abun- 

 dant but concolorous and not very conspicuous. Head densely squamose, the 

 constriction rather feeble ; beak in the female slender, distinctly, evenly 

 arcuate, rather densely squamose in basal half but nude, polished, minutely, 

 sparsely punctate thence to the apex, about three-fifths as long as the elytra ; 

 antennae inserted at apical two-fifths, the second funicular joint but slightly 

 longer than the third. Prothorax very nearly as long as wide, the sides broadly, 

 feebly arcuate and gradually convergent, nearly straight and not perceptibly 

 constricted anteriorly to the apex, the latter three- fourths as wide as the base ; 

 sculpture entirely concealed by the dense even crust of scales. Elytra at base 

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

 than wide, the sides straight and parallel in basal half, then angulato-para- 

 bolic ; striae indicated only by narrow and rather ill-defined partings of the 

 vestiture. Length 1.9 mm. ; width 0.85 mm. 



Texas. 



The single female before me represents a species somewhat allied 

 to silaceus, but decidedly different in its shorter, broader form, 

 wider elytra, longer beak in the female and uniformly, densely 

 covered pronotum. 



14 S. vestitus Lee— Proc. Am. Phil. Soc, XV, p. 172. 



Rather narrowly oblong-oval, convex, blackish, the beak, antennae, 

 legs and elytra rufo-testaceous, the latter with the suture and base 

 clouded with piceous ; vestiture consisting of rather small elongate- 

 oval yellowish scales, moderately dense, sometimes quite sparse, not 

 mottled, intermixed with distinct recurved setae. Beak in the male 

 short, stout, feebly arcuate, tapering, smooth and nude toward apex, 

 scarcely longer than the head and prothorax, with the antennae in- 

 serted at apical two-fifths, in the female much longer, smooth, cylin- 

 drical, subglabrous and subimpunctate, slightly squamose toward 

 base, evenly, moderately arcuate, rather more than one-half as long
