 an apical lunule, inflected iii front. Head granulate and bairy in front, finely 

 striate each side the eyes but not all the way between them ; labrum evidently 

 three toothed more acutely in females; thorax short, narrowed behind, impres- 

 sions deep and scarcely colored at base ; elytra gradually wider behind the humeri,

Var. Iioriconensis n. var. 

 Length 14-15 mm.=.56-.60 inch. 



Habitat. — Lake George, N. Y.; Hamilton, Canada; Mt. Desert, 

 Maine; N. 111.; Wis. 



Differs in color and in being more hairy. The head and thorax 

 are cupreous above and beneath, the impressions of the thorax 

 tinged with green ; the elytra are cupreous, with the bases of the 

 thickly placed punctures metallic green, producing an effect of 

 green-bronze. Beneath metallic green, varied with cupreous on the 

 pleurae and legs. The color varies, and in some specimens the green 

 shade is the more prominent, in others the cupreous, but in all there 

 is a marked brilliancy of color that contrasts strongly with the black 

 forms of the Pine Barrens of New Jersey and the races that inhabit 

 the more southern States.
