Originally described from the Middle States. Recorded 

 in the Smith Catalogue for New Jersey, and from New York 

 in Bull. 189, N. Y. Exper. Sta. 1900. Represented in col- 

 lection by two specimens from Berlin, Germany, (C. Schirmer) 

 labeled Agromyza schineri Loew, in Coquillett's handwriting. 

 The only other specimen I have ever seen was reared from 

 asparagus by I. J. Condit, Portsmouth, Virginia, submitted 

 by Prof. Chittenden of the Bureau of Entomology. 



This species attacks asparagus and in the New York Bul- 

 letin above mentioned is an account of its life history. Giard* 

 has found it in France, and Collinf in England, associated 

 with the same plant.
