80 JAMES E. COLI.IN — A NEW FLY OF THE GENUS AGROMYZA, &C. 



Q . Difficult to distinguish from the male, the ovipositor being withdrawn within 

 the last abdominal segment, and the tubular basal part very short. 



Length 2^—2^ mm. ■ 



The species of Ac/romyza are very difficult to name because very few have 

 been described with sufficient accuracy, but there does not appear to be any species 

 known with the characters given above ; the extreme shortness of the tubular 

 ovipositor, usually so conspicuous in the females of Agromyza, is somewhat 

 remarkable. 



A. salicifolii was bred by Mr. F. C. Willcocks, Entomologist to the Khedivial 

 Agricultural Society, from mines in willow leaves found at Gizeh, Lower Egypt, 

 in April, 1910.
