Genus EPIMYIA, new genus, type E. Carolina, new species.* 

 Male. — Length, i mm. Antennse sparsely haired, nearly black; probably 

 14 segments, the fifth with a stem one fourth the length of the subcylindric 

 basal enlargement, which latter has a length two and one half times its diam- 

 eter and a sparse basal whorl of stout setae. Palpi triarticulate. Head, meso- 

 notum and abdomen dark brown, the basal segment of the latter fuscous yel- 

 lowish. Wings hyaline, the third vein uniting with costa at the distal fourth, 

 the simple fifth at the basal half. Halteres fuscous. Legs dark brown ; claws 

 simple, the pulvilli about two thirds the length of the claws. Genitalia : basal 

 clasp segment stout, truncate, the ventral angle produced, setose ; terminal 

 clasp segment irregular, apically with a long, recurved spine ; dorsal plate 

 deeply and roundly emarginate, the internal angles of the lobes produced, re- 

 curved, acute : ventral plate long, narrow, broadly and roundly emarginate, 

 the lobes produced and tapering to an obtuse, sparsely setose apex. 

 Type Cecid ai62i, X. Y. State Museum. 



Readily separated from the preceding gentis by the triarticulate 

 palpi. North America. 



Genus LEDOMYIELLA Meun. 1904, type L. succini Meun. 

 An amber species with the wing membrane scaled, the fifth vein 

 forked; tarsi qtiinquearticulate, the metatarsus shorter than the 

 second segment; palpi quadriarticulate. 



Genus BRACHYNEURA Rond. 1846, type B. fuscogrisea Rond. 

 Distinguished from the preceding by the three simple long veins 

 and the triarticulate palpi. Europe, North America, Australia. 



Genus OLIGARCES Mein. 1865, type O. paradoxus Alein. 

 Small species, easily separated from other allies by the biarticidate 

 tarsi. Europe and North .America. 



Subfamily Itonidin.e. 

 A group comprising by far the larger number of species and in- 

 cluding practically all of the gall-making forms. Metatarsus always 

 shorter than the following segment, the wings with three or four 

 long veins; circumfili present. 



Tribe EPIDOSARIJE. 

 A distinct cross-vein uniting the third vein and subcosta and 

 usually parallel with costa suffices to distinguish members of this 

 group.
