pennipes group is well separated from the radiata group not only in 

 facies but on leg, wing and abdomen characters, notwithstanding that 

 these largely become in the latter group tertiary sexual characters 

 consisting in form and color of abdomen and coloration of wings, 

 with ciliation of hind legs, etc. The description of the new genus and 

 statements of synonymy are as follows : 



Trichopodopsis new genus. 



■^ Synonym, Trichopoda s. str. Townsend, 1908 (nee Latreille). 



Differs from Galactomyia, Eutrichopoda and Trichiopoda as fol- 

 lows : Abdomen nearly same form in both sexes, more or less flattened, 

 not cylindric in female; concolorous in both sexes, light yellowish, 

 reddish or ferruginous, and without any black in female. Scutellum 

 always black. Wings with inner margin abruptly very narrowly 

 hyaline, the hyaline border not over about one fifth of wing width, in 

 female the wings otherwise wholly black, in male black usually with 

 yellow splotch but no milky radiations ; apical cell usually very short 

 petiolate. Femora never wholly yellow or ferruginous, the hind femora 

 not at all ciliate in either sex, the hind tibiae ciliate only on about the 

 lower or distal half. Parasitic in Heteroptera {Anasa, Leptoglossus) 

 so far as known. Deposits flat-oval macrotype eggs on host. 



Trichiopoda Latreille. 



Type, Miisca (Dictya) pennipes J. C. Fab,/ 



Synonyms, Trichopoda auct. pt. Polistomyia Townsend. 



Parasitic in Acridiidae (Dissosteira) so far as known. Deposits 

 flat-oval macrotype eggs on host. Described in Tax. Muse. Flies 

 (1908), pp. 132-133.
