Dear Sir, 
* — 
I thank you for your letter of 28th March, 
and. for the specimens of flies which you have bred from 
beans. Ihese insects undoubtedly belong to a species 
of Agromyza , but the material is in such poor condition, 
owing to the specimens having been preserved in spirit, 
that I find it impossible to identify them with certainty. 
I shall, however, be sending them shortly to Prof. Bezzi, 
and will let you know as soon as I hear from him about 
them. 
I remain
