is also marked with a small black patch, almost obsolete in the 

 female. The wings of both sexes reach well beyond the tip of 

 the abdomen; the elytra of the male are without stigma or col- 

 ored or coraceous costal margin, and the wings are wholly hya- 

 line except for an almost imperceptible dark tinge apically; in 

 the female the elytra are green with rounded brownish stigmae, 

 the anal field transparent for most its length and the costal field 

 about one-fourth as broad as the entire elytral width ; the wings 

 of the female are hyaline with the tips tinged with green and the 

 rest deeply marked with yellow. The elytra of both sexes fail 

 to reach the tip of the wings when at rest, in the male lacking 

 about four millimeters.
