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- 
tenee that since Cecidomy ia Jor I tomuidia “pan eG: 
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 under 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
