16 S. pleiiralis n. sp. — Robust, oblong-oval, convex, black, the legs red 

 with the tarsi darker, extremely densely clothed above with large scales, ab- 

 ruptly white in lateral sixth of the pronotum and more than lateral fourth of 

 the elytra, elsewhere above dark red-brown, smaller, whitish, very dense 

 beneath ; brown scales above easily denuded, the white more persistent. Head 

 finely granulate, obscurely areolate ; transverse impression feeble ; beak rather 

 slender, distinctly arcuate, strongly punctured throughout, opaque toward 

 base, squamulose, the scales suberect laterally toward base, equal in length 

 to the head and prothorax ; antennae inserted a little beyond the middle, the 

 basal joint of the funicle about as long as the next two, second rather more 

 than one-half longer than the third. Prothorax very nearly as long as wide ; 

 sides parallel, broadly, evenly arcuate, convergent and distinctly constricted 

 very near the apex, the latter two-thirds as wide as the base ; disk where 

 denuded strongly, rather closely, evenly perferato-punctate, the interspaces 

 narrow but smooth and polished. Elytra at base one-third wider than the 

 prothorax, two and one-half times as long, not more than one-third longer 

 than wide, nearly straight and parallel at the sides in basal half, then nar- 

 rowly parabolic, with the convergent sides nearly straight ; strise fine, deep 

 toward the middle when denuded. Length 2.0 mm. ; width 1.0 mm. 



Arizona. 



A single specimen which is probably a female ; the second ventral 

 segment is minutely but quite distinctly angulated posteriorly at the 

 sides. 



17 S. olbtectus Lee— Proc. Am. Phil. Soc, XV, p. 171. 



Oblong-oval, convex, deep black throughout, polished when de- 

 nuded, the pronotum then strongly, closely, evenly punctured ; 

 integuments densely clothed with rather large, deeply and coarsely 

 strigose, elongate-oval scales, widely overlapping longitudinally on 

 the elytra, dark brown in color, very feebly and indefinitely mottled 

 with cinereous toward the sides ; recurved setae as usual. Beak in 

 the male rather thick, feebly arcuate, densely squamose, opaque, 

 scarcely longer than the prothorax, the antennae inserted near apical 

 two-fifths, in the female slightly thinner, nearly straight, as long- 

 as the head and prothorax, otherwise similar to that of the male, 

 the antennte inserted just visibly beyond the middle; basal squamu- 

 lose tufts very prominent ; antennae moderate, the basal joint of 

 the funicle subequal to the next three, second one-half longer than 

 the third. Prothorax large and long, fully as long as wide, the 

 sides parallel and broadly arcuate, becoming convergent and strongly 

 constricted toward apex, the latter three-fourths as wide as the base. 

 Elytra at base not more than one-third wider than the prothorax,
