THE LEPIDOPTERA OF 
LINCOLNSHIRE. 
PART TV; 
By G. W. Mason, 
Barton-on-Humber. 
I have included in ‘this part the whole of the so-called Micro- 
Lepidoptera, so as to have all the records together, and consequently 
the easier for reference. My labour for the time being is ended, the 
compilation having given me the greatest pleasure. I must apologize 
for my initials appearing so frequently and prominently in the following 
Records, but in view of there being so few workers among the Tortrices 
and still less among the Tinez I have thought it as well to give in detail 
so far as reasonably necessary the dates of my own captures and those 
of other persons, except in the case of the most abundant species. 
The lack of workers in this branch of study arises, I fancy, 
from the absence of modern and popular works on the subject and 
within reach of a moderate purse. As a beginner, I felt very much 
confused, but what a delight it is to take up a fresh subject when every- 
thing is new. I have found Stainton’s Manual of the very greatest 
assistance in helping me to classify and name species, and for the 
generous help of Miss E. Maude Alderson, of Worksop, and Mr. E. A. 
Atmore, of King’s Lynn, who have without stint of labour and patience 
corrected my determinations and named other specimens which baffled 
me, I cannot adequately express my heartfelt thanks. They have 
always esteemed it a pleasure to look over any box of insects that I 
happened to send them, whether belonging to my own collection or to 
another person’s which had been sent to me for correction. Mr. Louis 
B. Prout, Mr. Harwood and the late Mr. J. W. Tutt have also had a 
hand in identification. 
Much work still remains to be done, and this List is nothing like 
complete ; species new to the County keep turning up each year, which 
makes the work all the more interesting.
