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.

Pedicia rivosa, L. is probably the most strik- ing species, it is usually common in Blackroot Bog and is handsome and conspicuous 159
