bat the two short fixed spurs of the posterior tibiae are visible; 

 they are very short, approximate, and truncate. 



It is more slender and with less inflated elytra than ohscurus, 

 as represented in the cabinet of Dr. LeOonte; it is also decid- 

 edly smaller than that species. The specimens from Humboldt 

 Co. are slightly smaller than those from Mendocino and differ 

 in having slightly shorter, more convex and inflated elytra, with 

 paler but more distinct markings, but more especially in the 

 form of the prothorax which is decidedly more strongly inflated 

 in the middle, and in the vestiture of the under surface of the 

 abdomen, which in the Humboldt specimens is completely de- 

 void of broad scales toward apex, while in the southern speci- 

 mens there is a decided admixture of such scales. In antennal 

 structure it fulfills the tabular character, and it can only be at 

 best a local variety of significans. 



S, bruinali§ n. sp. — Nearly uniform dark grayish-brown through- 

 out, a posteriorly arcuate, very feeble, and ill-defined band crossing the 

 elytra at the summit of the apical declivity; prothorax very slightly 

 paler at the sides. Head and beak as long as the prothorax, rapidly 

 narrowed from base to apex; alae very slightly dilated; eyes at less than 

 their own length from the base; surface nearly as in significans, the 

 median carina being a little stronger and continuous along the apical 

 depressed glabrous area; the latter not forming a closed angle; antenneB 

 long, slender; scape rather strongly arcuate; funicle not incrassate, first 

 joint one-third longer than the second, seventh very long, two-thirds 

 longer than the sixth. Prothorax slightly wider than long, subcylin- 

 drical, very slightly more convex at the middle of the sides; base slightly 

 narrower than the apex, both transversely truncate; disk rather finely, 

 deeply, and very sparsely punctate, sparsely clothed with small semi- 

 erect pale setae which are much smaller and less squamiform than those 

 of the head. Elytra inflated, oblong-oval, more than twice as wide as 

 the prothorax, a little more than one-third longer than wide, rather 

 acutely rounded behind; sides arcuate, nearly straight for a short dis- 

 tance in the middle; disk convex, rather fiat near the suture, not per- 

 ceptibly tumid near the suture behind, rather finely and deeply striate; 

 striae finely and not closely punctate; intervals feebly convex, each with 

 a row of rather robust, nearly erect, pale, subsquamiform setae. Abdomen 

 more sparsely squamose toward apex, sparsely covered with rather long, 

 recumbent whitish setae; first suture very slightly arcuate for a very 

 short distance in the middle; second nearly as long as the next two 

 together. Length 5.5 mm.
