NOTTINGHAMSHIRE DIPTERA: A PRELIMINARY. LIST.

Jatural History ae eet ae Museum of Science and Art. 
THE following list of Diptera, comprising over 240 species, is 
mainly the result of the zeal of my friend the Rev. Alfred 
Thornley, M.A., of South Leverton, who during the past four 
years has paid considerable attention to this much-neglected 
order of insects, and who has very kindly submitted the greater 
part of his collection to me for examination. From the large 
number of specimens examined Mr. Thornley has very generously 
allowed me to select for the Edinburgh Museum any that 
deemed of use, and accordingly, our collections have been enriched 
by his kindness to the extent of nearly 500 specimens. The 
majority of Mr. Thornley’s Nottinghamshire collecting was done 
in a small area, including the localities of South Leverton and 
Treswell. 
Mr. Thornley’s Nottinghamshire List has been increased by 
1892, by Messrs. R. C. Bradley and Colbran J. Wainwright and 
friends. These are acknowledged in the proper place. It is 
hoped that the present contribution, the result of the labours of 
these gentlemen, may serve as a foundation upon which to build 
at some future date a more or less complete Dipterous fauna 
of the county of Nottingham. A few critical notes have been 
added at the end of the list, and the species dealt with in these 
notes are marked with an asterisk in the list. 
It only remains for me now to tender my thanks to Messrs. 
G. H. Verrall and R. H. Meade for assistance in identifying 
a dozen species about which I had some doubt, and also to 
_ Mr. Thornley for the great trouble he has taken in incorporating 
for me the numerous records of Messrs. Bradley, Wainwright, 
and others. :
