tarsi quite black; middle femur with a short, well- 

 developed comb near the tip on the hind side below; 

 middle tibia with two bristles on the outer front side 

 and no villosity; hind tibia with rather short villosity 

 on the mesial side; both middle and hind tibias have 

 on the exterior surface two rows of small hairs widely 

 separated by a bare space from any other hairs. 



Wings hyaline, no costal spines ; third costal seg-' 

 ment rather longer than the fifth; first vein bare; 

 third vein hairy halfway to crossvein. 



Female. Front .290 of head (average of two, — ■ 

 .285 and .295) ; outer vertical bristles distinct. Third 

 segment of abdomen without median marginals in the 

 described specimen. Genital segments yellow, shin- 

 ing above; without specialized larvipositor. Middle 

 and hind tibiae on the extensor surface as in the male. 



Length 7.5 to 10 mm. 



Eleven males and two females: Seven males 

 and two females Tifton, Ga., in the Hough collection; 

 one male Kushla, Ala., June 11, 1914 (Sturtevant) ; 

 three males Enola, Va., May 1, 1915, reared from 

 Sparoholus sp. (a myriopod) by Sara Reynolds.

Like singularis except in the following respects. 

 Front .235 of head. Hind tibia almost without vil- 

 losity, there being only three or four erect hairs on 

 the mesial side which are, however, barely equal to 

 the diameter of the tibia. In singularis the hind tar- 

 sus is perceptibly shorter than its tibia (42:46 by mi- 

 crometer measurement in the type) ; in deceptiva the 

 proportion is reversed and the tarsus is longer than 

 its tibia (37:33). In deceptiva the forceps are only 

 once concave at the base and do not have the diverg- 

 ing lateral arm; the penis has a much lower keel, 

 ending in a plain point at the apex; the organs are
