292 On Some New 



very finely attenuate, arcuate; pale setae short, very sparse, scarcely 

 twice as long as the darker ones; each elytron has a small, subapical 

 umbo on which the dark setae are extremely' dense. Length 3.5-4.0 

 mm. 



California (San Diego 2). 



The second ventral segment is much shorter than the next 

 two combined, and the base of the abdomen is broadly and fee- 

 bly impressed ; surface densely squamose throughout; first suture 

 broadly and feebly arcuate in the middle, 



S. liispidiceps n. sp. — Form elongate, convex; scales moderate, 

 rounded, truncate, finely but distinctly strigose, cinereous at the sides, 

 indefinitely clouded with pale brown toward the suture, dense, but sel- 

 dom overlapping on the elytra. Head small, robust, distinctly wider 

 than long; front and basal half of beak flat, coarsely and deeply punc- 

 tate, with finer punctures on the interspaces, bristling with long erect 

 setae, and shorter, paler, more recumbent ones near the surface; the 

 latter almost devoid of scales, except near the eyes; beak as long as the 

 head, slightly wider than long, feebly declivous and distinctly impressed 

 at apex, the impression divided as usual by a distinct carina; lateral cari- 

 nas fine and strongly elevated; impression distinctly limited behind by 

 a more declivous surface; eyes large, inner margin rather distinctly 

 elevated; antennae rufous, rather slender, nearly as in prominens. Pro- 

 thorax distinctly wider than long, cylindrical; base and apex equal, 

 very feebly arcuate; sides rather distinctly constricted very near the 

 apex, broadly and feebly arcuate in the middle; disk convex, rather 

 finely and densely punctate; scales rather dense, obscuring the punc- 

 tures, but sparser than those of the elytra, not forming distinct vittae; 

 setae pale brown, rather long, fine and dense, especially toward the me- 

 dian line. Elytra fully twice as long as wide, formed nearly as in 

 prominens; subapical umbones feebler; disk feebly striate; striae finely 

 and not very distinctly punctate; intervals subequal, nearly flat; setae as 

 in prominens. Abdomen impressed in the middle at base. Length 4.5- 

 4.8 mm. 



Arizona (exact locality not given 2). 



This species greatly resembles the last in outward form, but dif- 

 fers very remarkably in its larger, less elongate-oval, and very 

 much more coarsely and distinctly strigose scales, by the denser 

 scales of the prothorax, and finer pronotal punctuation. The 

 punctures of the elytral strias are much less distinct, and the 

 color of the vestiture is more whitish and less brown. 



S, angu§tulu§ n. sp. — Form elongate and rather slender, convex; 

 scales pale brownish-gray, feebly variegated with cinereous at Jhe sides,
