at the sides to the base ; apical constriction fine, deep, entire, the lobe short, 

 two-thirds as -wide as the base; caualiculation barely traceable; lateral impres- 

 ^ions feeble. Elytra scarcely more than twice as long as wide, more than twice 

 as \Nide as the prothorax, parabolic in apical fourth; sides parallel; impression 

 within the humeri feeble; humeri obliquely truncate at base; disk moderately 

 strongly punctate, with the interspaces finely punctulate. Abdomen finely, 

 densely punctate and pubescent; legs rather slender. Length 6.3 mm.; 

 "width 1.9 mm. 



California (Los Angeles Co.). 



The t3'pe appears to be a male. Incanus is related to jjrw- 

 inosus, but difters in its more obese form and much denser vesti- 

 ture. 



S. Tariipes. — Rather slender and convex, black, the elytra shining, with- 

 out any kind of metallic lustre; pubescence rather sparse, not concealing the 

 surface sculpture even on the anterior parts. Head not coarsely but very 

 densely rugoso-punctate, much wider than long, the ej-es separated by about 

 twice their own width; tempora large, rather more prominent than the eyes 

 and three-fourths as long; auteunse very slender, much longer than the head 

 and prothorax together, the l)asal joint not paler. Prothorax sculptured like 

 the head, not quite as long as wide, strongly rounded at the sides anteriorly, 

 thence deeply sinuate to the base, which is but slightly narrower than the maxi- 

 mum width; apical constriction evident, the lobe short; caualiculation fine, 

 very distinct; lateral impressions distinct but situated on the extreme flanks. 

 Elytra distinctly more than twice as long as wide, barely twice as wide as the 

 prothorax, parabolic in apical fourth; sides parallel; humeri broadly, obliquely 

 rounded at base; punctures moderately coarse, deep, separated by about their 

 own widths. Under surface minutely, densely punctate and pubescent. 

 Length 8.0 mm. ; ^vidth 2.0 mm. 



California (Yreka, Siskiyou Co.). 



Allied onh' to indutus^ but diflering in its larger size, heavier 

 prothorax with much stronger median sulcus, differently colored 

 legs, larger tempora and several other features; it is represented 

 by a single specimen of undetermined sex. 



S. iiidutus. — Moderately slender and convex, black thi-oughout, the 

 Ijolished lustre of the elytra feebly appearing through the close even vestiture 

 of cinereous tint. Head slightly transverse, densely, not coarsely rugoso-punc- 

 tate and dull; eyes large, separated by twice their own width on the front; 

 tempora one-half as long as the eye; antennae slender, much longer than the 

 head and prothorax combined. Prothorax about as long as wide, sculptured 

 like the head, rounded on the sides anteriorly, sinuate posteriorly, the base 

 dilated as usual and but slightly narrower than the anterior parts of the disk ; 

 apical constriction fine, entire; caualiculation fine or subobsolete; lateral im- 

 2)ressions distinct and extending obliquely on the disk. Elytra twice as wide
