Bright green or blue-green, the abdomen more golden-green,

 whitish, in the J* generally somewhat yellowish upon the upper 

 half. Front shining, generally blue-green, seldom blue or green. 

 Antennas yellowish-red ; third joint short-ovate, generally slightly 

 infuscated at the tip ; arista with a distinct pubescence. Cilia of 

 the inferior orbit yellowish-white. Humeral callosity yellowish. 

 The callosity between the root of the wing and the scutellum is 

 usually of the same color and* generally also the margin of the

 brown color often begins before the tip of the third joint and the

 middle and hind tarsi, whilst in darker specimens a distinct infus- 

 cation already begins in the middle of the first joint. Wings 

 grayish, somewhat more yellowish-brown towards the fore margin ;
