YORKSHIRE PTYCHOPTERA, INCLUDING 
P. LONGICAUDA, NEW TO THE BRITISH LIST. 
CHRIS. A. CHEETHAM. 
In Verrall’s List of British Diptera, 1901, there are five species 
of Pty diopter a, and keys to the same species are given in 
Wingate’s Durham Diptera, all of which have been recorded 
for our county. Recently M. Tonnoir* described two addi- 
tional species, one of which, P. minuta Tonn. has been found 
in several places in Britain. Mr. F. W. Edwards, who 
identified this species for me, and brought M. Tonnoir’s paper 
to my notice, cites : Spey Bridge, Nethy Bridge and Aviemore, 
Inverness (Yerbury), Lyndhurst, Hants (Yerbury), Hitchen, 
Herts. (F.W.E.), Notts. (Carr). In addition to Austwick, 
where it is recorded from in the list in Nat., 1921, p. 410. I 
have taken it at Gormire, and seen a specimen taken by Mr. 
G. T. Porritt at Hornsea. 
Tonnoir’s other species, P. longicauda, has not yet been 
recorded for Britain. I find, however, that I took a q 
of this species at Mickley Woods last August. With. this, all 
the British species have been found in Yorkshire. I have 
collected all but paludosa Mg. (Nat., 1908, p. 104), and in 
working over the genus with Wingate’s keys, had difficulty
