througliout; horn differing greatl\' in tlie sexes, strongl\', closely, moderately 

 coarsely and exenly dentellate throughout, hroadly rounded, expanded, 

 strongly constricted at hasc, narrow in the male, very broadly patellate in the 

 female; crest very long, narrow, defined at the sides hy a strongly crenulate 

 raised line, undefined at apex. Elytra twice as long as wide, rather less in the 

 female, somewhat oval and convex, the sides parallel and feebly, equally 

 arcuate, obtusely rounded behind, narrowly and obliquely truncate in the 

 male; humeral impression feeble; punctures not coarse but strong, moderately 

 distant; decumbent pubescence rather short, but somewhat coarse and close; 

 erect settc long but line, sparse and inconspicuous. Length 2.9-3.4 mm.; 

 width 1.0-1.4 mm. 



California (Alameda Co.). 



The peculiar oval convex form of the elytra, and departure 

 from the usual t^'pe of ornamentation w'ill readil}' distinguish this 

 species from serratus and robustus, to which it is somewhat re- 

 lated. It is smaller than serratus^ with a much longer, narrower 

 and more ill-defined thoracic crest and shorter, more oval and 

 convex elytra. The female is much stouter than the male. It is 

 represented by three si)eciraens. 



IV. pictiijii. — Narrow, elongate and parallel, rather dull, piceo-tcstaceous. 

 black beneath, the legs and antennsc pale; elytra with the markings piceous 

 the large scutellar spot frequently obsolete, the anterior fascia occasionally 

 disintegrated into two large sublateral spots and an elongate and more pos- 

 terior sutural area, the latter always joining the transverse post-median fascia; 

 apices always i)ale. Ihad small, much smaller than the prothorax, the pol- 

 ished surface not much concealed by the moderately dense vestiture; eyes 

 moderate, about as long as the tempora; antenuii; long and slender, about two- 

 fifths as long as the body. Prothorax transversely oval, finely, not very densely 

 punctate, polished, coarsely, somewhat sparsely pubescent, the tomentose line 

 very widely and completely interrupted; horn long, narrow, not distinctly 

 dentellate, parallel, rounded at apex, not at all constricted, the surface deeply 

 concave and coarsely reticulate, the crest abrupt, elevated, very short, rotuuled 

 at apex and defined throughout by an elevated and entire margin. Kli/tra 

 elongate, distinctly more than twice as long as wide, one-half wider than the 

 prothorax, the sides parallel and nearly straight, gradually rounded behind in 

 apical third to the feebly oblique apical truncature, w Inch is defined by a small 

 dentiform projection; humeral impression distinct, the others wholly obsolete; 

 disk finely, closely punctiite, the vestiture moderate in length but rather coarse 

 and dense as usual, assuming tints nearly corresponding to the ground color; 

 erect setaj somewhat short, sparse and not very conspicuous. I^ength 3.6-3.8 

 mm.; width 1.15 mm.

The description refers to the male, and this sex has, in addi-
