I have not seen this species, and cannot place it in my 

 synoptic table from the characters given in the description. 

 No species of Agromyza that I have seen has only two scutellar 

 bristles, and the palpi are remarkably large for a species of this 

 genus. The head, with the exception of the palpi, as figured, 

 looks like an Agromyza, but the arista is rather strongly pubes- 

 cent, for most of the species in that genus. I suspect that it 

 does not belong here, and the head figured on page 292 in 

 Williston's Manual, which is quite evidently a reproduction 

 of his figure 158 on Plate 14 of the original publication of the 

 description, being given as "Agromyza (nov. gen.?)" in the 

 Manual, would seem to indicate that Williston also thought 

 so in 1903, whatever he may have thought in 1896. No 

 indication is given as to the specific identity of the species, 

 or source from which figure came in the Manual.
