PRELIMINARY LIST OF 
THE NEUROPTERA AND TRICHOPTERA OF 
YORKSHIRE 
(OMITTING PSOCID2 AND EPHEMERID/). 
G: T.: PORRITT,: F.L.S.;-F-E.S., 
Crosland Hall, Huddersfield. 
As nearly ten years have now elapsed since I made an appeal in 
this Journal (see ‘Naturalist,’ June 1887, p. 180), in connection 
with these insects, it seems desirable that an account of what has 
been done should be placed on record. ‘The list is very far 
from complete as representing the species which must occur in 
our large county, and it will continue to be so until we have 
more workers on these orders. To me the study of them has 
been, and still is, an intense pleasure. No other group of insects 
can be more advantageously worked—indeed, perhaps none so well 
—along with the lepidoptera; and if I can induce some of the 
students of the more fashionable order to take an interest in these 
as well (together they only contain a comparatively small number of 
species), I am sure they will be more than repaid, and may, indeed, 
in time come to regard them as the more fascinating groups. It is 
worth noting in this connection, that with one exception, all our 
present-day British neuropterists and trichopterists have commenced 
their entomological career as lepidopterists. 
Some of the members of our Union, and others outside it, 
have assisted me right well by sending specimens they have 
casually captured whilst working at their own special ite oe and 
in this connection I must especially thank Messrs. G. C. Dennis, 
John Harrison, S. L. Mosley, William Hewett, B. sioaes, 
William Mansbridge, and J. W. Carter. 
PSEUDO-NEUROPTERA. 
ODONATA. 
Leucorrhinia dubia. I have taken this rather local species on 
Thorne Moor at the end of May. 
Sympetrum scoticum. Abounds on Thorne Moor and Riccall 
Common, and no doubt on other similar heaths. 
Libellula quadrimaculata. Thorne Moor. 
lula fulva. Mr. S. L. Mosley took several specimens of this 
very rare dragonfly at Askern in June 1888, one of which 
I have in my collection. 
#&schna juncea. Sandburn, York. 
April 1897.
