580 MR. CLAUDE MORLEY ON THE INSECTS OF THE BRECK. 
and, by exchange, of their own collections. Agrophila 
sulphuralis has occurred singly in several parts of Suffolk, 
but is now confined to a small portion of the Breck, where 
it still flourishes. I well remember the glee with which the 
late Mr. E. G. J. Sparke one day told me that a “ dealer” 
had just asked him where he could find this Moth, and the 
former had directed him to a spot where it but sparingly 
occurred, while they had been actually chatting on its head- 
quarters ; “ These dealers,” he added, with a twinkle, “ are 
not oculatissimi ” ! I have on one or two occasions taken 
Lithostege griseala at Brandon, attracted by artificial light 
at night, but have no idea of its frequency or distribution, 
except that it is “ confined to the Breck.” The handsome 
Spilodes sticticalis and small Tinea imella are equally limited 
in their range, though I do not consider they have bred from 
generation to generation here, as Mr. Clarke would have us 
believe ; like the late Professor Westwood, I am by no means 
a staunch evolutionist in the generally accepted sense of the 
term, but I certainly believe considerable changes in our 
insect-fauna have taken place since the post-glacial period. 
The single Coleopteron peculiar to Brandon is Diastictus 
vulneratus which was first discovered to be a British species 
by me in June, 1902, when I found one specimen beneath 
rabbits’ exuviae. In May of the following year, the late 
Mr. A. J. Chitty, M.A., F.E.S., and I both took a specimen 
as far as we could reach down the holes of rabbits at the 
same spot, and finally early in the same month last year he 
took the fourth specimen in a similar manner. This species 
has a somewhat extended Continental range, appears to be 
nowhere common, and has been found in similar high, sandy 
situations in the vicinity of Lyons. 
The insect-fauna of secondary importance comprises those 
species attached to an arenaceous soil wherever it crops out. 
A great many of these are common on all the sandhills of our 
coasts, especially at Deal and Felixstowe ; the very much 
wider extent of their pabulum in the Breck renders their 
propagation more profuse and certain, for here there is no 
danger of being blown cither out to sea or across the cultivated
