INSECTS 





least uncertain as to identification. There has been no attempt to 

 make a complete list, but rather to supply the nucleus of one and to give 

 an idea of the more characteristic dipterous insects of the county fauna. 



The system and nomenclature is according to Verrall's List of British 

 Diptera published in 1901. 



My thanks are due to Mr. Verrall for assistance and advice in the 

 preparation of the list ; to Mr. R. C. Bradley for much information 

 which I have included ; and to the Rev. J. H. Bloom, who assisted me 

 by collecting a few Diptera at Whitchurch.

 ing species, it is usually common in Blackroot 

 Bog and is handsome and conspicuous
