thorax. In one of the males, the prothorax is distinctly 

 smaller, shorter, and more strongly rounded at the sides. There 

 may be several varieties indicated by these characters, but they 

 are too indefinite to describe. 



This species is larger, more slender, and more sparsely 

 squamose than vittatus Lee. 



S. marg^aritosiis n. sp. — Rather slender; integuments black; scales 

 sparse, large, pure pearly white and pale brown confusedly intermingled 

 in small nebulous patches, subvittate at the sides and middle of the pro" 

 notum, rather sparsely placed, being distinctly separated over the entire 

 surface, rounded, coarsely and strongly strigose, sparse on the abdomen 

 which is more densely setose. Head small, slightly transverse, feebly 

 conical; eyes large, at less than one-half their length from the base; sur- 

 face of head and beak flat, finely, densely punctate, uniformly covered 

 with large, conspicuous, white, and feebly embrunate scales, except a 

 large, angulate, feebly impressed area at the apex of the beak which is 

 not squamose, but covered with the short, pale, robust setae which are also 

 distinct over the entire surface; median groove very fine, feeble, and in- 

 conspicuous; antennae rather short; first joint of funicle distinctly more 

 robust, slightly longer than the next two together, the latter small, sub- 

 equal in length. Prothorax widest at the middle, distinctly wider than 

 long; sides distinctly and evenly arcuate in the middle, convergent and 

 straight to the base, equally convergent and feebly sinuate toward 

 apex; apex truncate; base equal in width, feebly arcuate; disk convex,, 

 coarsely, very deeply, and densely punctate, the punctures obscured by 

 the scales; dark areas densely covered with short, robust, pale brown 

 setae; pale vittae with a very few similar pure white setae. Elytra nearly 

 twice as long as wide, not one-half wider than the prothorax, acutely 

 rounded at apex; sides parallel, nearly straight; disk convex, feebly 

 striate; striae with moderately coarse, but slightly distinct punctures^ 

 intervals feebly convex, slightly unequal in width; small, pale brown 

 setae rather dense, long, erect; white setae very sparse, wanting toward 

 the base and suture. Length 4.0 mm. 



California (Santa Cruz and Monterey Cos. 2). 



A very distinct species by reason of the large pearly, sparsely 

 placed scales. The punctures of the elytral striae are but slightly 

 distinct, except when the easily abraded scales are removed. 



According to the description given by Fahrens, this species ap- 

 pears to resemble californiciis more closely than any other, but 

 the scales are large and sparse, and the expression ^' cinereo- 

 tomentosus " cannot be properly applied. The scutellum more- 

 over is not concolorous, but white. 



S. proceru$$ n. sp. — Elongate, convex; scales very dark brown.
