throughout; horn differing greatly in the sexes, strongly, closely, moderately 

 coarsely and evenly dentellate throughout, broadly rounded, expanded, 

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

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

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

 female, somcAvhat 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 fine, 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 type of ornamentation will readil}' distinguish this 

 species from sei-ratus and robustiis, to which it is somewhat re- 

 lated. It is smaller than senrifus, 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 specimens. 



]V. pictllS. — Narrow, elongate and parallel, rather dull, piceo-testaceous, 

 black beneath, the legs and antennse 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 pale. Head small, much smaller than the prothorax, the pol- 

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

 moderate, about as long as the tempora; antennte 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 Avidely 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, rounded 

 at apex and defined throughout by an elevated and entire margin. Elytra 

 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, which is defined by a small 

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

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

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

 erect set« somewhat short, sparse and not very conspicuous. Length 3.6-3.8 

 mm.; width 1.15 mm.

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

 tion, the fifth ventral sinuato-truncate in the middle at apex, the
