D, Prosternum sparsely pubescent, not densely punctate in either 

 sex ; tibial dilatation rather narrow ; under surface 



typically green carinipennis Lee. 



DD. Prosternum densely punctate and rather densely pubescent 

 in the male ; tibial dilatation shorter and broader. 

 E. Prothorax more abruptly narrowed in front than behind ; 

 sculptured areas of elytra not very densely punctate, 

 smooth spaces narrower, body bronzed beneath. 



trinervia, Kby. 



EE. Prothorax as abruptly or even more abruptly narrowed 



behind than in front ; punctured spaces of elytra very 



densely punctate and dull, smooth areas broader ; 



body beneath bright green in the male, blackish green 



in the female sylvania n. sp. 



AA. Prosternum with a short broad lobe in front. 



F. Tibial dilatation rather abruptly narrowed before the apex ; emargina- 

 tion of last ventral of female limited at bottom by a thin slightly 

 projecting and deflexed plate ; prosternal lobe very short. 



caurina Horn. 



FF. Tibial dilatation of male not abruptly narrowed before the apex; 



last ventral of female without apical plate. 



G. Tibial dilatation of male short and broad, a little sinuate on its 



inner margin, the apical angle mucronate, tibia deeply sinuate 



at base of dilatation ; prosternal lobe very short, .breviloba n. sp. 



GG. Tibial dilatation rather strongly arcuate internally, the tibia a 



little narrowed at base of dilatation, but not evidently sinuate ; 



prosternal lobe stronger nionticola n. sp. 



C. californica Lee. 



Seven specimens are placed over this label in the LeConte col- 

 lection, the series standing precisely as left by Horn, who worked 

 over the material while preparing his monograph of the genus. The 

 first in line and bearing the name label is unquestionably the original 

 type of LeConte. It is a male, 17 mm. in length, sculpture cupreous, 

 beneath also coppery, eyes separated above by somewhat more than 

 half their vertical length ; prothorax widest just before the base, 

 sides converging a little in front and sinuate at middle, dorsal channel 

 deep with broad smooth callosity each side reaching from the apex 

 three-fourths to the base ; elytral sculpture of the same type as in 

 related species, very densely punctate, smooth spaces not strongly 

 elevated, sutural costa entire ; prosternum without the faintest indica- 

 tion of a lobe in front, dilatation of front tibia unusually long and 

 narrow, one-third the length of the tibia, which is not at all sinuate
