From Francis Walker 1 February 1861
Grove | Highgate
Febry. 1st. 61.
My dear Sir,
Mr. F. Smith has given me two Dipterous Species forwarded by you to him for the names.1 One “aboundant on T. officinalis” is Dolichopus nigripennis, (Fallén) a common species The other “sucking Euphrasia” is Empis chioptera (Fallen) also common,2 the male with milk-white wings, very different in appearance from the dark-winged female.—3
I was not able to attend to the Aphides last year, but I will endeavour to make use of your suggestions respecting them & to study as much as I can, the inquiry as to species.—4
Believe me, yours sincerely, | F. Walker
