164 CHARLES W. LENG. 



lunule entirely consumed by the broad white margin " is Dejean's 

 expression. Head striate between the eyes, hairy to the occiput; 

 hibrum short, unidentate ; thorax flat, granulate, thinly clothed 

 with white hairs; elytra punctate, except in the white parts, sinuate 

 at the apex, the sinuation forming a very blunt tooth or suggestion 

 of a tooth in the 9 ; beneath, densely clothed with white hairs, ex- 

 cept at the middle, even to the head below the eyes ; color dark 

 green, shining, trochanters all rufous, tibise, palpi and tarsi pale; 

 legs very long. 



Very rare in collections. Not found recently.

 Soc, 1876, p. 238; Schanpp, I.e., p. 100, pi. 4, fig. 81. 

 Length 12-14 nim.=.48-.56 inch. 



Habitat. — Ky., Kan., Mo., Ark., Tex., Neb., Dak., on the banks 

 of rivers and on sand-bars. 



Cupreous or greenish bronze above, shining; beneath green, tro- 

 chanters all rufous ; elytral markings follow the same pattern as in 

 the preceding, but are much narrower. Other characters as in the 

 preceding, except the sexual which are : 



Male. — Elytra obliquely sinuate at apex, suture not retracted, tip 

 obtuse. 



Females. — Elytra emarginate externally at apex, with a subapical 

 tooth acute and prominent ; suture feebly retracted, tip rounded. 



This species is widely distributed and has developed into geo- 

 graphical races which are difficult to distinguish, except by the 

 sexual characters and the locality labels. The specimens taken by 

 Mr. Charles Dury at Newport, Ky., on bottom lands are shorter and 

 broader and indicate an undescribed race; as do also the specimens 

 from Texas with very slender markings. In the absence of abund- 

 ant material and in view of the difficulty of separating the varie- 

 ties already described, I include these forms with cuprascens, where 

 all doubtful specimens should be placed for the present.
