striate; striae very finely and not distinctly punctate; fifth interval with 

 a small, pale, yellowish spot at base. Length 6.5 mm.

This species is peculiar in its more elongate seventh funicular 

 joint and more elongate eyes. The tarsal claws are robust and 

 strongly arcuate, each has a long, slender basal appendage, 

 which character is generic, the appendage being in some species 

 longer and in others shorter. 



S. variaas n. sp. — Slender, convex; scales cinereous, small, rounded, 

 dense, sparser on the dark areas of theprothorax; base of head trivittate; 

 prothorax distinctly trivittate, with pale, subcupreous scales, remain- 

 der piceous; alternate intervals of elytra pale and dark, giving a regu- 

 larly vittate appearance; abdomen pale, squamose, and setose through- 

 out. Head slightly wider than long, feebly conical; front flat; surface 

 of head and beak coarsely, deeply, and densely punctate, rather sparsely 

 squamose and with very short, robust, inconspicuous setae; frontal 

 fovea elongate, narrow, deep, prolonged anteriorly through the basal 

 half of the beak in a fine channel; beak not as long as and distinctly nar- 

 rower than the head, as long as wide, scarcely dilated at apex; surface 

 broadly, feebly impressed, not impressed at apex; eyes large, broadly 

 convex; antennae moderate, piceous; scape rufous; first joint of funicle 

 as long as the next two together, second longer than the third. Pro- 

 thorax about as long as wide, cylindrical, broadly and feebly con- 

 stricted at the sides near the apex. Sides broadly arcuate, feebly 

 sinuate very near the base; apex and base equal, broadly and very feebly 

 arcuate; disk evenly convex, rather finely, deeply, and densely punc- 

 tate: punctures but slightly 'covered in the dark areas; minute setae 

 short and as dense as the scales. Elytra twice as long as wide, not one- 

 half wider than the prothorax, acutely rounded at apex; sides parallel 

 and nearly straight; disk convex, finely and feebly striate, striae finely 

 punctate; intervals alternately slightly broader and narrower, feebly con- 

 vex; dark setae moderately numerous, small; longer pale setae very 

 sparse, wanting near the suture toward base; dark scales of narrower 

 intervals not so dense as those of the wider pale intervals; scales all 

 finely, deeply, and very distinctly strigose. Legs moderate, piceous; 

 tarsi and sometimes the tibiae paler rufous. Length 3.8-5.0 mm.

The above description is taken from the male, which is much 

 smaller and more slender than the female. Of the thirteen 

 specimens before me, there are four males, and of these the type 

 is the only one exhibiting the vittate elytra with any degree of 

 distinctness. The females have the elytra very indefinitely 

 vittate or confusedly maculate, and have a more transverse pro-
