90 AiV 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 Linnjea Entomologica is of so much value. Other 

 works of importance on this family are quoted below :
