This is a variable species iu color and markings, and the names 

 which have been given to it refer to these variations. The follow- 

 ing are known to me : 



Scutellaris Say.— Head and thorax usually green sometimes blue; 

 elytra all cupreous, or sometimes partially .suffused with green from 

 the base down, or even green partially suffused from the apex cupre- 

 ously; usually immaculate, rarely with the apical lunule and a mar- 

 ginal dot. Occurs in Colo. ; Kan. ; Neb. Sports also occur approach- 

 ing the color of Lecontei. 



Var. unicolor Dej.— Green or blue immaculate. Occurs in Mass. 

 (an occasional specimen among many rvgifrons) ; N. C. ; S. C. ; Fla. ; 

 Ala.; La.; Tex.; Colo, (rarely). I have one specimen from Wil- 

 mington, N. C, in which the color is purplish green, intermediate 

 between this variety and scutellaris. 



Var. modesta Dej.— Black, with apical lunule and one or two 

 marginal dots rarely confluent. An occasional specimen exhibits a 

 dull green reflection. Occurs in N. Y. ; N. J. ; Fa. 



Var. nigrior Schaupp.— All black, immaculate. Occurs in N. Y. 

 (an occasional specimen among many modesta) ; Ga. ; Fla. ; Ala. 



Var. rugifrons Dej. — Green or blue, with apical lunule, and one 

 or two marginal dots, rarely confluent. Occurs in Mass. ; R. L ; 

 N. Y. ; N. J. ; Md. ; N. C. 



Var. Lecontei Hald.— Cupreous, coppery bronze or greenish bronze 

 with apical lunule, one spot or often two spots, or even with a humeral 

 spot as well, all of which in Canadian specimens become confluent.
