Among the specimens before me the females vary in length from 

 3^-4^4 mm., and the males from 2^-4^2 nini. The length of the 

 ovipositor is considerably less than that indicated by Westwood, being from 

 .7-1.3 mm. The antennae are inserted farther from each other than from 

 the eye margin. The scape is greenish, with a metallic lustre. In both 

 sexes the posterior femora vary from dusky to yellowish brown, there being 

 no reddish at the base in these specimens. The white spot at the base of 

 the posterior tibiae is confined to the upper basal third, and is bounded by 

 a straight diagonal line in most of the specimens ; in two- males from 

 Florida and one male from Tuscon, Ariz., it surrounds the base; in a male 

 from Santa Cruz Mts., Cal., and a female from Panamint Mts., Cal., the 

 spot is shorter and broader, and bounded by a curved instead of a straight 

 line. The specimens from Florida and the South-west have the posterior

tibite more strongly dilated than the Eastern forms (Fig. 20) ; the 

 Virginian forms have the white spot long and narrow as in the Northern 

 specimens, while the tibiae are intermediate in width.
