LIST OP BRITISH 8YRPHID&. 



BY G. H. VERRALL. 



As I wish to rescue the British Di/ptera from the state of confusion 

 in which they exist in most collections, I offer a systematic list of one 

 of the most attractive families ; hoping, in course of time, to supplement 

 it with others. As Mr. Walker, in the " Diptera Britannica," has 

 described 153 species of Syrphidce, and I now give only 166, and even 

 some of these doubtfully, I have not materially increased our number 

 of species ; but upwards of 20 of Walker's are sunk as varieties, and in 

 many cases the nomenclature has been brought more into agreement 

 with that in use on the continent. When I have marked a species 

 with an asterisk, I have not been able to critically examine it, but 

 believe it to be truly British. I intend to supplement the list with 

 short notes upon a number of the species ; and as a caution, I may 

 remark that I do not consider it at all exhaustive, but anticipate 

 raising it to at least 200 species.
