Type locality. — Arlington, Virginia. 



Type.— Cat. No. 2294, U.S.N.M. Type selected. 



Redescribed from the two types in the National Museum. They 

 were reared March 30, 1886, from Cecidomyia faj'inosa Osten Sacken 

 found on blackberry. Ashmead'^ says that Prof. J. B. Smith has 

 reared the same species from a gall on blackberry at New Brunswick, 

 New Jersey. I have not seen the specimens and can not verify his 

 determination.
