DIPTERA 



Flies 



This list contains about 950 species out of the 3,000 odd species 

 of Diptera at present known to be British. This is as large a list as any 

 county at present gives. This satisfactory result is owing to the county 

 having been worked at times by Mr. G. H. Verrall, the well known 

 authority on British Diptera. It is through his friendship that I have 

 been enabled myself to add many species to the list. The eastern part 

 of the district has been well worked by the Rev. E. N. Bloomfield,
