furrow not attaining the middle of the beak; the latter robust, distinctly- 

 shorter than the head, slightly wider than long; antennae moderate; 

 first joint of funicle scarcely as long as the next two combined, second 

 distinctly elongate. Prothorax slightly wider than long, widest in the 

 middle; sides feebly arcuate, thence feebly convergent and nearly 

 straight to the base, finely, deeply constricted at the sides at anterior 

 sixth; apex truncate, distinctly narrower than the base; the latter very 

 feebly arcuate; disk slightly flattened above, finely, densely punctate; 

 pale brownish setae, dense toward middle and directed transversely. 

 Elytra oblong, three-fourths longer than wide, more than three-fourths 

 wider than the prothorax, acutely rounded behind; sides parallel and 

 nearly straight; roundly and rather strongly emarginate at base, finely 

 and rather feebly striate; strias with moderate rather distant punctures, 

 intervals subequal, rather feebly convex; pale brown setae very abun- 

 dant, rather long, fine and capillary; erect white setae very sparse, and 

 but slightly longer than the darker ones. Length 6.0 mm. 



California (Healdsburg, Sonoma Co. 2). 



This fine species is remarkable in the total absence of a median 

 pronotal vitta, in its large size, comparatively distinct elytral 

 punctures, and pale cinereous color, with the alternate intervals 

 laterally, distinctly, but unevenly tesselate with pale brown. It 

 is the species identified as californicus by LeConte, but this de- 

 termination is probably erroneous, because of the absence of the 

 median vitta, a prominent character of californicus. 



S. eximius n. sp. — Form elongate, convex; scales moderate or rather 

 large, oval, slightly longer than wide, finely and distinctly strigose and 

 flat, densely placed although not overlapping, sparse on the dark areas 

 of the pronotum, generally whitish, especially in a broad, indefinite line 

 from each humerus to the sutural portions of the elytral apex; sutural 

 portions of disk feebly maculate with pale brown, and a broad vitta on 

 each fiank of the same tint; pronotum distinctly trivittate. Head mod- 

 erate, slightly transverse; occiput feebly convex; front and beak flat, 

 finely, densely, and deeply punctate, densely squamose; scales much 

 longer than wide; setae short, robust, and not conspicuous; median 

 groove fine but distinct, slightly expanded on the front and attaining 

 the middle of the beak; the latter nearly as long as the head, very 

 slightly wider than long; eyes rather small, feebly convex; antennae 

 moderate; first joint of funicle slightly longer than the next two to- 

 gether, the latter subequal and both slightly elongate. Prothorax nearly 

 one-third wider than long; sides distinctly arcuate, nearly straight 

 toward base, very finely constricted at the sides at less than anterior 

 sixth; apex very slightly narrower than the base, subtruncate; base 

 broadly and feebly arcuate; disk convex, finely, densely punctate; setae 

 of dark areas very short and robust; median vitta broad and distinct,
