go AN ACCOUNT OF BRITISH FLIES. 
mentioned in the list of Diptera found at Hastings, etc. Yet with a 
little trouble a great many may be captured. I have taken as many 
as ten different species myself on the windows of a single room on 
one wet afternoon. With careful collecting a large number may be 
met with, and many new species to the English fauna are sure to be 
captured. Verrall gives a long list of reputed species, none of which 
have been dealt with here ; many of these are recorded and described 
in Walker’s “ Diptera Insecta Britannica,” but until further evidence 
is found they will be left out of the British list ; by degrees, no doubt, 
they will all find their way back again, but at the present rate it will 
take many years. Amongst those who have done most for this 
family must be mentioned Winnertz, whose “ Monographie der Gall- 
mucken ” in the Linnzea Entomologica is of so much value. Other 
works of importance on this family are quoted below:
