JOHNSONOMYIA n. g. 



This g-enus is erected for several small forms apparently 

 closely allied to Colpodia Winn., in that the wings are long, 

 narrow, and the cross vein not parallel with costa. Members 

 of this genus may be recognized by the simple unbranched 

 fifth vein and also by the somewhat broader wings and shorter 

 legs than obtain in Colpodia. It is distinguished at once from 

 Bryocrypta Kiefif. by the simple fifth vein [pi. 39, fig. 4].

pomncoNDYLA Rond. 

 This genus may be recognized by the cross vein being parallel 

 or nearly so with costa, and the fifth vein forked, in connection 

 with the greatly produced antennal segments of both sexes. See 

 plate 39, figures 2, 5 and 8 for wing characters. The genitalia 

 are variable and in some species very striking [see pi. 44].
