[143] HYMENOPTERA 149 



femora and tibiae, except their apices, obfuscated or light brownish ; 

 wings hyaline, the veins brownish-yellow. 



The antennae are long, filiform, longer than the body, i4-jointed; 

 the flagellar joints i to 3 are the longest joints, the first straight, cylin- 

 drical, more than twice as long as thick, the second and third some- 

 what thickened and both curved, thrice as long as thick, the following 

 joints slender, hardly more than twice as long as thick and clothed 

 with a short, fine pubescence. Thorax as in Allotria. Wings nearly 

 twice the length of the body, the marginal cell being open all along 

 the front margin, the second abscissa of the radius being curved and 

 nearly twice the length of the first. 



Female. Length i .5 mm. Agrees well with the male except that 

 the head is castaneous, the yellow of the face beginning a little 

 above the insertion of the antennae, the first five joints of the antennae 

 and the legs being yellow, the rest of the antennae being brown-black. 



The antennae are as long as the body, i4-jointed, slightly thickened 

 toward apex, the joints of the flagellum elongate, the second and third 

 joints of same being longer than the first, the second being longer than 

 the third, and the longest joint of all, the following joints to the last 

 being nearly equal in length, the last being longer than the penultimate.

Type in British Museum. From Kodiak, July 20 ; Popof Island, 

 July ; Virgin Bay, June 24. Four specimens. 



Originally described from Hudson Bay Territory. It is a parasite 

 on Cecidomyia communis Barnston MS. The four specimens taken 

 are without much doubt referable to this species. They exhibit con- 

 siderable variation in color of the antennal scape and of the legs. The 

 scape is most frequently metallic, though sometimes wholly yellow 

 beneath, or with only a yellow spot at extreme base, the legs varying 

 in the amount of green on the femora and of brown on the tibiae.
