This genus comprises a large number of medium and rather 

 small, usually dark brown insects which breed by preference in 

 leafy tissues. The group intergrades with Rhabdophaga and the 

 more typical forms may be distinguished therefrom by the heavy, 

 nearly uniform third vein uniting with the margin well before the 

 apex of the wing. The type is Dasineura luteofusca 

 Rond. 



There has been in earlier years a most unfortunate disagreement 

 as to the concept represented by the genus Cecidomyia. A number 

 of the earlier authors have insisted on applying this generic designa- 

 tion to a series of species which we have referred to this genus 

 and its allied forms. Contemporaries of some of these earlier 

 writers have insisted, and we believe rightfully, that Cecidomyia 

 could be applied only to a series of insects represented by the 

 Cecidomyia pini of DeGeer and have used the term Dasy- 

 neura for species referable to this group. The consequence has
