subsessile; segment 2 occupying about one-fourth of surface. 

 Legs normal ; hind tibial spur slender. Forewings ample ; the 

 marginal cilia rather long; marginal vein as long as the 

 submarginal, over twice as long as the postmarginal, which 

 is nearly twice as long as the stigmal, the latter of moderate 

 length. Antennae inserted in middle or slightly above middle 

 of face, far above ventral ends of eyes; scape, pedicel, one 

 ring, and four funicle joints, the club 3-jointed, including a 

 nipple-like third joint which is apparently articulated ; funicle 

 joints long and filiform. 



d . Antenna! joints of same number as in the female, 

 the first three funicle joints each bearing a long ramus. 



Of the Hemiptarsenine genera with 4-jointed funicle, 

 Sympiesonecremnus, Girault, and N ecremnomyia , Girault, 

 bear two ring joints, and Elachertonecremnus, Girault, has 

 short clavate antennae which are situated below middle of 

 face and below ventral ends of the eyes. Allied with 

 Dimmockia, Ashmead, and Diaulomella, Girault, of the 

 Eidopkini, but careful examination of several hind tibiae 

 revealed no second tibial spur. The insertion of the antennae 

 and the non-advanced axillae appear distinctive. 



Neodimmockia agromyzae, n. sp. 



9 • Length, 1*50 mm. Rather dark blue-green ; the 

 coxae concolorous, also posterior femora and basal half of 

 intermediate femora, the legs otherwise white, the anterior 

 tibiae faintly edged darker, the anterior tarsi dusky, also 

 other tarsi (except their basal joint) and apical third of pos- 

 terior tibiae ; antennae black, the scape suffused with white,, 

 the apical two club joints pale whitish. 



Scape slender ; pedicel over one-half longer than greatest 

 width; funicle 1 over twice as long as pedicel, 2 and 3 a little 

 shorter than 1, 4 distinctly so; club about as long as funicle 

 2, joint 1 distinctly longer than 2. Thorax densely reticulate 

 in raised lines ; on scutellum with a longitudinal tendency ; 

 propodeum with fine impressed reticulation ; scutellum with a 

 single seta on either side of meson posteriorly. Wings hyaline. 



d ■ Length, 1'25 mm. Colorationally like the female. 

 Antennae wholly black; pedicel one-half longer than wide; 

 funicle 1 no longer than pedicel, 2 twice as long as 1, 3 

 slightly longer than 2, 4 two-thirds longer than 3 ; club a 

 little shorter than funicle 4 ; ramus on funicle 1 at base of 

 joint, on 2 and 3 at distal third.

 females bred from the bean-fly, Agromijia pl/axeoH, in stems 

 of cow-pea, August, 1915, A. P. Dodd).
