die one posteriorly abbreviated: collar incised, angles rounded; scutel-

 yellow, pectus deeper yellow ; metanotum blackish brown. 



Abdomen elongate oval, compressed, hairs pale; tergum blackish 

 brown, posterior margins of the segments paler; venter dull green, pos- 

 terior margins of the segments paler green: valves of the ovipositor 

 about as broad as long, racket-shaped, yellow. 



Wings hyaline, with distinct milky tinge, anterior veins heavy, yel- 

 lowish, with few setae ; posterior veins almost colorless ; posterior 

 branch of radius arched, ending slightly proximad of the tip of the 

 media, costa produced over one-fourth the distance beyond ' the tip 

 of the radius towards the tip of the media; wing surface finely and 

 irregularly roughened as in D. waltlii, without true punctations ; anal 

 lobe strongly produced, hind margin with a fringe of pale hairs. 

 Halteres white. 



Fore legs subfuscous, except coxae and extreme bases of femora 

 which are yellow, first tarsal segment over 0.8 as long as the tibia; 

 middle and hind legs, including coxae, yellow; knees, extreme tips of 

 tibiae and basal tarsal segments, and the whole of the last four tarsal 

 segments fuscous; tibial spurs distinct, posterior pairs longest; fourth 

 tarsal segments on all the legs broadened and emarginate apically, and

Ithaca, New York, May 30, 1914. 



The above description was largely drawn from a pinned 

 specimen which was later mounted on a slide. The type will 

 be placed in the Cornell University collection. The single pin- 

 ned paratype, from the same locality, does not differ from the 

 above. 



Though Kieffer mentions "hairy eyes" among the generic 

 characters of Diawesa sens, str., I am not inclined to erect a 

 new genus for the species on this character alone, especially as 

 the male is still unknown. ( )ur three species of Diatncsa as 

 now restricted may be distinguished as follows : 



</. Smaller species, female less than 2.5 mm. long ; thorax yellow ; 



eyes glabrous D. fulra n. sp. 



aa. Larger species, over 4 mm. long, thorax black or cinereous. 



b. Terminal antennal segment of male twice the length of the 

 others combined ; keel of the last tergite produced caudad about 

 as far as the apex of the basal segment of the clasper and 

 beyond the tip of the inner process of this segment (fig. 5, 



Muttkowski, 1915) /'. inciui^tuc. 



bb. Terminal antennal segment of male not over 1.0 times as
