lively moderate in size, fully as wide as long, broadly rounded 

 laterally, the sides strongly oblique and just visibly sinuate be- 

 hind the middle, the base narrow, much less than ^ the maximum 

 width and narrower than the head : basal angles much more than 

 right, not very blunt ; disk nearly flat, the impressions feeble, the 

 reflexed margins moderately deep and strong. Elytra suboblong- 

 oval, evenly and moderately convex, very full at the humeri, the 

 latter subtransversely rounded to the prothorax,^ longer than 

 wide, 3 times as long as the prothorax and 2^ times as wide ; striae 

 rather fine, equal, broadly and deeply impressed, coarsely and 

 crenately punctate, the intervals narrow and convex, confused 

 near the sides. Length 14.5-17.0 mm. ; width 6.7-7.6 mm. 



California (El Dorado Co.). The female is larger but almost 

 exactly resembles the male, having the elj'tra not at all more inflated 

 but longer, with the strial punctui'es less coarse, and the intervals 

 a little wider, less convex and more broadly and completely con- 

 fused near the sides. I have before me a male and three females 

 recently forwarded b}^ Mr. Rivers.

Rather stout and strongly ventricose, alutaceous, the elytra 

 shining, deep black in color. Head rather narrow and elongate, 

 the vertex nearly smooth ; supra-orbital ridges fine and rather 

 feeble, the inner slope of the portion above the antennae unusually 

 gradual ; gense with a small angulate notch ; antennae only 

 moderately slender and just visibly thicker basally, nearl}^ f as 

 long as the body, the basal joint distinctly thicker, obconic, much 

 shorter than the next two. Prothorax relatively well developed, 

 a little wider than long, inflated and rounded anteriorly, the sides 

 feebly subanguiate just before the middle, thence oblique to the 

 base, near which they are generally just visibly sinuate; angles 

 much more than right though scarcely at all blunt ; base ^ the 

 maximum width and as wide as the head ; disk feebly convex, the 

 impressions feeble, the fine median line distinct ; reflexed mar- 

 gins moderately strong. Elytra broadly oval, strongly convex, 

 very full at the humeri, scarcely ^ longer than wide, 3 times as 

 long as the prothorax but only 2^ times as wide, the reflexed 

 margin rather fine ; disk coarsely, closely and deeply striate, the 

 striae finely, feebly, scarcely obviously and distantly punctate, 

 the intervals strongly convex, partially interrupted even toward
