LIST OF LEPIDOPTERA 
TAKEN AT WYBERTON, NEAR BOSTON. 
J. C. LANE-CLAYPON, 
Tytton Hall, near Boston, Liucolushire. 
THE species enumerated below have nearly all occurred to me im 
the parish of Wyberton, which lies south of Boston, in District 17 
North of the Lincoinshire Naturalists’ Union Map. It will be of 
interest to publish this list at the same time as the report of the 
Lincolnshire Naturalists’ Union excursion to the district. 
A few notes about the physical features of the parish will be of 
interest. The parish from end to end is absolutely flat; it is 
practically entirely composed of fields (chiefly grass land), separated 
from each other by hedges or ditches. The district therefore 1s 
eminently unsuited for day collecting, indeed, the only locality worth 
visiting is the old Roman bank near the Witham, but ‘sugar’ and 
‘light’ usually yield fair results. There are no woods, but the trees 
are scattered fairly evenly though somewhat scantily over the parish. 
The commonest species indigenous to the district are elm, horse- 
chestnut, and ash, the first mentioned of which is the best for pupa 
digging. The soil is for the most part heavy clay; but near the 
river it becomes silt. ‘The absence of some species from the list 
which might otherwise be expected to appear in it may be accounted 
for by the fact that the vacation months of August and September 
are the only ones in which I have the opportunity for systematic 
collecting.
