The coloration of the present insect makes it the most l)eauti- 

 ful, and one of the most distinctive in appearance, of the North 

 American forms. The margins of the lateral lobes and of the 

 dorsum of the pronotum, the limbs, tegmina and cerci are a rich 

 and vivid green; the face and genae, sides of boch' just below 

 proximal portion of the tegmina and median areas of the lateral 

 lobes and the dorsum of the pronotum, are dark brown; the 

 dorsal surface of the head is marked with a median black line, 

 the portions between this and the eyes are yellowish brown. Tlie 

 abdomen is shining black, the dorsum of the same sometimes 

 dark brown, particularly in females.
