This, the oldest genus of the family, originally comprised all forms 

 referred to the very generally known Cecidomyiidae, now Itonididae, 

 and from about 1850 to 1890 or thereabouts there has been a lament- 

 able disagreement as to the genus. Some dipterologists of note have 

 held that Dasyneura or Perrisia and its allies were the true Cecid- 

 omyias, or Itonidas, while others have maintained with equal insis- 

 tence that since Cecidomyia or Itonida pini DeG. 

 was the type, this generic designation should be limited to forms 

 having the Diplosid structure. The genus Diplosis, erected by 

 Loew in 1850 for forms having binodose antennae in the male, has 

 been made a synonym of Cecidomyia, later giving way to Itonida, 

 and the genera formerly grouped imder this latter designation, are 

 now referred to Dasyneura or Perrisia and other genera. The 

 necessity of this change is regrettable, since Diplosis has been 

 invariably applied to certain insects having well defined general
