legs testaceous, posterior tibiae and tarsi pale brownish; wings clear 

 hyaline, stigma testaceous; first abdominal segment somewhat 

 tinged with blackish at base. 



Type locality. — Jemez Springs, New Mexico. 



Type. — In the Cornell University collection. 



Described from a single female specimen collected by John Wood- 

 gate, September 5, 1913.

The female of this species can be distinguished at once from our 

 other species, which have a broadening radiellan cell, by its much 

 longer ovipositor sheaths, which very nearly equal the length of the 

 abdomen. The male is not so easily separated by structural char- 

 acters; but the blackish markings in the thoracic sutures and usually 

 at base and apex of abdomen, the black apical half or third of pos- 

 terior tibiae, which contrasts strikingly with the pure white posterior 

 tarsi, in conjunction with a nervellus longer than the lower abscissa 

 of basella, will probably distinguish males of this species from those 

 of closely related species. The antennae of the unique type are 40- 

 segmented; other specimens show a range from 38 to 43 segments. 

 In the female the ocell-ocular line is a little shorter, while in the 

 males examined it is slightly longer, than the diameter of a lateral 

 ocellus. 



Distrihution. — Massachusetts, Maine, Canada. 



Host. — Unknown. 



The above notes are based on the following material : The type and 

 three additional specimens, all from Massachusetts, in the collection 

 of the Philadelphia Academy of Sciences; one female from Ottawa, 

 Canada, in the United States National Museum; four males, taken 

 at Eastport, Maine, and one from Capens, Maine, which are in the 

 collection of Dr. C. T. Brues, of Harvard University; and one male, 

 from Eastport, Maine, in the collection of the Boston Society of 

 Natural History.

This species is rather easily distinguished from related species by 

 the characters noted in the key. In color it is uniformly testaceous; 

 the stigma in female pale yellow, in male light brown; malar space 

 in male is distinctly more than half as long as basal width of man- 

 dible, in female much shorter; in all the specimens seen the lower
