ICHNEUMON-FLIES, PART 2 1 EPHIALTINAE 405 



orbital white mark ; flagellum with a broad white band ; metapleurum 

 with a white spot (rarely lacking) which is a little constricted next to 

 upper margin of metapleurum, the spot thus roundish or rounded 

 rectangular; front and middle coxae of male white, of female fulvous 

 or more or less white on outer side, in larger females often mostly 

 white; hind coxa fulvous with a short dorsal basal white stripe, or 

 this stripe more or less enlarged, in larger females often covering the 

 entire upper side of coxa; hind femur fulvous, its apex usually nar- 

 rowly infuscate, or sometimes the entire femur is more or less infus- 

 cate; paramedial white spots on fourth and fifth tergites of female 

 about 1.5 as high as long. 



The white mark of the temporal orbit is continuous across the top 

 of eye to the frontal orbit in most females and a few males from 

 eastern North America. Nearly all specimens from western North 

 America have the white orbital mark interrupted above. This differ- 

 ence between the eastern and western populations, though obvious, 

 does not seem constant enough for the recognition of separate sub- 

 species.
