marginal vein slightly less than half the length of the submarginal and 

 not quite twice the length of the postmarginal; abdomen lineolated, 

 not longer than the head and thorax; ovipositor about two-thirds 

 the length of the abdomen. Head and thorax brassy-green, the abdo- 

 men entirely bronze above, its sides slightly darker; antennae black, 

 slightly tinged with bronze; all coxae, trochanters, and femorae bronzy; 

 median and hind tibiae usually dark brown except at base and apex; 

 front tibiae, base and apex of hind and median tibiae, and all tarsi 

 yellowish; the apical tarsal joint brown. 



Male. — Similar to the female except that the head and thorax are 

 brighter blue-green and the femorae less tinged with bronze; the 

 third flagellar joint (first funicle joint) is often so reduced as to give 

 the appearance of three ring-joints. The same is true to a less extent 

 with the female.
