new or little-known crane-flies from the united states and 
canada: tipulid^, ptychopterid^, diptera. part 3. 
by charles p. alexander. 
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.^ 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.
