 Introduction. 



In this paper, the author has undertaken a review of the Nearctic 

 species of the difficult Eriopterine genus, Gonomyia, and has supplied 

 figures of the wings and hypopygia of the various species. The 

 remainder of the paper is in the nature of a continuation of the first 

 two papers under this title. 1 In order to complete the data in some 

 sections of the family, especially the genus Geranomyia, it has been 

 deemed advisable to add a few extra-limital species, most of these 

 being Antillean or Middle American forms whose northward range 

 is still not well understood.
