the angular notcli small and inconspicuous ; supra-orbital ridges moderately 

 strong and inwardly inclined at the antennae, fine posteriorly; antennae slen- 

 der, moderate in length, the basal joint distinctly thicker, claviform, not as 

 long as the next two, the seta at apical eighth. ProtJiorax well developed, 

 scarcely as long as wide, moderately dilated and broadly rounded throughout 

 anteriorly, the sides not more strongly rounded before, but becoming gradu- 

 ally oblique behind, the middle, to the base, with a scarcely visible ante-basal 

 sinuation; angles much more than right and bluntly rounded; base wide, 

 more than ^4 the maximum width and fully as wide as the head; disk feebly 

 convex, the median line strong; sublateral impressions deep, extending far 

 before the middle; reflexed margins rather fine. Elytra elongate-elliptical, 

 fully }4 longer than wide, nearly 2% times as long as the prothorax and 2% 

 "times as wide; humeri evenly and obliquely rounded; reflexed margins ample 

 but rather finely punctate; disk strongly, evenly convex, the striae deep and 

 broadly impressed, rather uneven, obscurely punctate, readily traceable 

 throughout the width, the intervals convex, much broken up toward the sides 

 and finely so toward the apex. Legs very slender. Length 17.5 mm. ; width 

 6.8 mm. 



Queen Charlotte Islands. 



This fine species is founded upon a single perfect specimen, 

 recently sent to me by Mr. Fletcher and probably taken by Mr, 

 Keen. It is a female, but the species will be readily known from 

 marginatus by its much larger size, more elongate and convex 

 elytra, larger and less posteriorly narrowed prothorax, with the 

 sides less sinuate towai'd base and several other characters.

Moderately elongate and ventricose, shining throughout, the 

 pronotum not distinctly alutaceous, black, the elj^tra cupreous-red 

 with bright metallic-green or brassy-green reflexed margins. Head 

 rather small, not much elongated, the vertex smooth ; supra-or- 

 bital ridges fine posteriorly ; gense very feebly developed with the 

 notch small ; antennae very slender, not |- as long as the bod}^, 

 the basal joint but slightly thickened and much shorter than the 

 next two. Prothorax relatively moderate is size, as long as wide, 

 the sides dilated and evenly rounded anteriorl^^, becoming ob- 

 lique and broadly, feebly sinuate to the base, which is narrow, ^ the 

 maximum width and barely as wide as the head ; angles much 

 more than right and very bluntly rounded ; disk but feebly convex, 

 the median line and two diverging sublateral impressions deep 

 and distinct, the latter extending to apical third ; reflexed margins
