A large proportion of the area under review is cultivated. 
The localities most productive of lepidopterous fauna are the 
coast sandhills, the mountain sides, the ‘“‘ mosses’’ (principally 
' in Cheshire), and the few tracts of woodland, such as Delamere 
Forest, Dunham Park, Tatton Park, &c. 
Although much work remains still to be done, especially in 
Wales, a considerable amount has been accomplished, and many 
additional species have been recorded, since MR. WALKER’S list 
was published. A revision and extension of that list was 
therefore thought desirable, and the following pages are the 
result. We may mention, incidentally, that the introduction of 
electric lighting has been the means of attracting several species 
not hitherto known to occur in the district, besides showing the 
more frequent occurrence of others previously considered rare. 
The nomenclature and arrangement of genera have been 
changed from those of MR. WALKER’S list, and have been 
brought more into accordance with recent publications. The 
classification and names adopted are those of Staudinger and 
Rebel’s Catalogue of 1901, which, though open to objections, 
may, we think, be followed with advantage until a more 
acceptable list is forthcoming. 
It was intended to include the remaining genera of the 
Micro-lepidoptera; but, while records for Cheshire are fairly 
numerous, those for North Wales are at present so meagre, 
that it was thought advisable to defer dealing with them until 
more information should be available. It is a matter for regret 
that so little attention has been paid, especially in North Wales, 
to this branch of Lepidoptera. 
We have drawn liberally on DR. J. W. ELLIS’S publication, 
The Lepidopterous Fauna.of Lancashire and Cheshire, for records 
of Cheshire insects, and gratefully acknowledge our indebted- 
ness to this source. Our thanks are also due to MR. CHARLES 
OLDHAM, who has extracted a number of interesting records 
from early volumes of Zhe Zoologist; and to the following 
Entomologists, who have been good enough to furnish us with 
the records resulting from their work in the district :—
