North American Rhynchophora. 289 



or subtruncate, very coarsely, deeply, and distinctly strigose; abdomen 

 gray, more sparsely squamose and setose. Head and beak finely and 

 densely punctate, densely squamose, and with numerous, robust, erect 

 setae, flat; median groove fine; beak slightly wider than long; antennae 

 short, robust, rufous; first joint of funicle much more robust, much 

 longer than the next two together, two to four short, subequal, monili- 

 form, second very slightly the longer. Prothorax widest slightly before 

 the middle, one-fourth wider than long; sides feebly arcuate, feebly con- 

 vergent and nearly straight toward base, feebly sinuate near the apex; 

 the latter subtruncate, scarcely narrower than the base; disk convex, 

 densely punctate; dark setae short and very robust; scales nearly all 

 pale, but more sparse on the dark areas. Elytra four-fifths longer 

 than wide, less than one-half wider than the prothorax; sides straight 

 and parallel, broadly rounded from just behind the middle and acutely 

 rounded behind; disk convex, finely striate; striae finely and not dis- 

 tinctly punctate; intervals convex, the alternate ones distinctly more 

 strongly so; dark setae extremely short, robust, and not very numerous; 

 pale setae very sparse, short, and robust, nearly twice as long as the 

 darker ones. Length 4.0 mm. 



California (exact locality unknown 1). 



A small and rather obscure species, but which may possibly 

 be recognized by the large, deeply strigose, pronotal scales, 

 nearly uniformly pale in color, but much sparser in the dark 

 vittse, and by the elytral intervals being alternately decidedly 

 more strongly elevated. The abdominal scales are elongate, finely 

 strigose, and simple near the base, but only one-half as long, 

 smaller, oval, and feebly plumose near the apex. 



S. sordidus Lee. — Rather robust; scales dark-brown throughout, 

 small, oval, very finely and indistinctly strigose on the elytra, more 

 coarsely so on the pronotum, dense but not overlapping, thick, and 

 slightly convex ; abdomen densely squamose and setose. Head mod- 

 erate, slightly transverse; eyes rather small, very slightly longer than 

 wide, at nearly their own length from the base ; front flat, very feebly 

 impressed laterally, very densely squamose and with fine, short, incon- 

 spicuous setae ; median groove narrow and deep ; beak nearly as long as 

 wide ; scrobes not visible from above ; apex broadly, angularly im- 

 pressed, densely punctate, sparsely setose, and finely squamulose; an- 

 tennae moderate ; first joint of funicle slightly longer than the next 

 two together, second elongate. Prothorax rather distinctly wider 

 than long, widest just before the middle; sides distinctly arcuate, dis- 

 tinctly sinuate near the apex, and more broadly and feebly so near the 

 base ; apex very slightly narrower than the base, both very broadly 

 and feebly arcuate; disk convex, finely, densely, deeply punctate, the 

 sides not distinctly paler, and the median vitta scarcely distinguish-
