Locality doubtful. 



The male, which is the type of the above description, represents 

 a species closely allied to marginatus, but differing in its Jess an- 

 teriorly inflated prothorax, with feebler reflexed margins and 

 much straighter oblique sides, more narrowh'' elongate-elliptical 

 elytra, with less impressed and ver}^ much less defined elytral 

 striae, in its rather smaller size, more seneous and less coppery- 

 red elj'^tra and other characters. The anterior tarsi are moder- 

 ately dilated, with the soles very finely and extremely densely 

 papillose, that of the first joint small, rounded and occupying 

 scarcely apical third, the fourth without papillae beneath ; the in- 

 tercoxal plate of the mesosternum is deeply concave. The female 

 is larger, with the prothorax relatively smaller, but otherwise 

 similar, and the elytra but little more broadly elliptical and not 

 at all fuller at the humeri. The two examples before me are 

 without indication of locality, but were undoubtedly taken at 

 some point on the coast between northern California and Alaslia.

Rather elongate and moderately ventricose, highly polished 

 throughout and deep black, sometimes with a faint violaceous 

 metallic reflection. Head rather small, moderately elongate, the 

 transverse nuchal constriction behind the e^^es distinct though 

 shallow ; vertex perfectly smooth ; genae very feebly developed, 

 the notch small or evanescent ; supra-orbital ridges becoming 

 fine posteriorly ; antennae slender, scarcely f as long as the body, 

 the basal joint moderately thickened, but longer than the next 

 two, the seta between apical fifth and sixth. Prothorax relatively 

 moderate in size, nearly as long as wide, rounded anteriorly, nar- 

 rowly rounded just before the middle, the sides rather strongly 

 sinuate nearer the base than usual, the angles nearly right and 

 bluntly rounded ; base ^ the maximum width and as wide as the 

 head ; disk feeblj^ convex, the median line rather distinct, the 

 sublateral impressions parallel and strong, ending abruptly at 

 basal "I; side margins moderately reflexed. Elytra elongate, sub- 

 <3ordiform, nearly ^ longer than wide, 3 times as long as the pro- 

 thorax and about 2^ times as wide, full toward the humeri, 

 which are strongly and subtransversely rounded at base, gradu- 

 ally pointed and rounded in ogive behind the middle ; margins 

 well reflexed and coarsely punctured ; disk very depressed, nar-
