Walker's description. As both sexes were taken the same day 

 and at the same spot, alonu- a path in the hills back of the town, 

 I have no doubt but that they are the same species, though the 

 female differs considerably from the male. The following is a de- 

 scription of the female, which has not been described: — 



Length <S mm. Face and front yellowish ; vertex green ; oral 

 margins brownish; antennae reddish; aristiie black. Thorax and 

 scutellum green ; a slender line of yellow extends from the humeri 

 to the base of the wings (also present in the male). Abdomen 

 much wider than in the male, bluish-green, second segment concave 

 at the sides, with a central yellow spot at the base; pubescence on the 

 posterior borders of the segments more prominent than in the male. 

 Venter bluish, the second segment, and the posterior margin of the 

 third and fourth narrowly margined with yellow. Front and 

 middle legs yellow; posterior femora with outer half of the tibite 

 and tarsi brownish- black, base of the femora and basal half of the 

 tibiie and tarsi yellow. In the color of the posterior legs occurs the 

 greatest difference, though the outer portions of the femora, tibite, 

 and tarsi of the male are noticeably darker.
