groove very deep, wide, and conspicuous; eyes large, inner margin 

 slightly elevated; beak with large lunate impression in apical half, the 

 sides carinate, median carina in the form of an elongate tubercle: 

 antennae slender, slightly longer than usual, piceous-black; first joint of 

 funicle distinctly longer than the next two together, second to fourth 

 elongate, the former much longer than the third. Prothorax cylindri- 

 cal, distinctly wider than long, with a rather abrupt, distinct constric- 

 tion at apical sixth; sides broadly, subangularly arcuate; disk convex, 

 rather finely and densely punctate; punctures deep, generally separated 

 by their own widths; setae small, piceous, abundant, but not con- 

 spicuous; base and apex equal, broadly and very feebly arcuate. Elytra 

 four-fifths longer than wide; sides parallel and straight in basal U\ u- 

 thirds; disk moderately convex, rather distinctly striate; striae with 

 round, deep, and very distinct punctures, usually separated by nearly 

 twice their own diameters; intervals subequal, nearly flat; dark fetee 

 rather large, robust, rapidly and finely attenuate, very abund \;ir 

 piceous and not conspicuous; pale setae rather abundant and twice as 

 long as the darker ones. First abdominal suture broadly and subangu- 

 larly emarginate throughout its width: second segment slightly shorter 

 than the next two together; setae white, very dense and unusually con- 

 spicuous. Length 5.3 mm. 



California (San Diego 1). 



This species is remarkably distinct from all the others here 

 described, in its dark, piceous vestiture, longer antennal scape, 

 and distinct elytral punctures. It is described from the female. 



S. apacheanu§ n. sp. — Somewhat robust and flattened above; 

 scales rather large, rounded, finely, distinctly strigose, very dense, 

 overlapping, dark brown and paler confusedly intermingled, present- 

 ing a feebly tesselated appearance on the alternate intervals; pronotum 

 with narrow, feeble median vitta, and slightly paler sides; abdomen 

 whitish, very densely squamose and setose, the scales elongate and 

 finely plumose. Head rather robust, distinctly transverse; front fiat; 

 surface of head and beak coarsely, very sparsely squamose in the middle: 

 more densely so laterally, densely bristling with fine, erect setae; 

 median groove fine but deep; beak shorter than the head, wider than 

 long; basal half on same plane as the front, but broadly and feebly im- 

 pressed; apex feebly declivous and impressed, feebly carinate in the 

 middle, sparsely, finely squamose, and more sparsely setose; lateral 

 carinas more distinct than usual, also more discal and distinctly con- 

 vergent from apex to base; scrobes more than usually visible from 

 above; antennae moderate; first joint of the funicle one-third the 

 length of the latter, slender, as long as the next two together, second 

 elongate, much longer than the third, third and fourth subequal, both 

 elongate, five to seven shorter, strongly incrassate. Prothorax cylih-
