THE WEEKLY ENTOMOLOGIST. 
flat cylinder with a slight angular 
projection on one side. In this box 
were four varieties of Arctia caja bred 
from larvae fed upon Petasites vulgaris 
to test Mr. Gregson’ s paper on variety 
breeding. Three of them were dark, 
and one light. 
M r. Gregson exhibited a series of 
Gelechia immundella. Doug, varying 
from the beautiful pale form, with 
black spots to very dark specimens 
with white markings, like Gelechia 
affinis, and observed that he had this 
year taken the light and dark speci- 
mens in cop. free-ly from 2 to 4 p. m. 
on the sand bills in May 
Mr. Gregson laid the first eight 
nrmbers of the “ Weekly Entom- 
ologist ” on the table, aud observed 
that he hoped all the members would 
support it. 
Mr. Hodkginson exhibited a box of 
interesting specimens, among which 
were Notodonta dodoncea etc. etc. 
Mr. G. 1L Wilkinson exhibited a 
box containing Noctua Sobrina taken 
by John Stafford at Rannoch on sugar 
in August last. 
A discussion then took place on a 
paper by Mr. Brown, read at the 
previous meeting, on the mutability 
of species. 
During this discussion the Secretary 
read a letter from Professor West- 
wood, possessing great interest [but 
which, unfortunately, space forbids 
our inserting here] in the course of 
Avhich he highly complimented the 
Northern Entomological Society on 
the great activity which exists among 
its members, and their evident desire 
to go further than the mere collecting 
of specimens. 
With a vote of thanks to the visi- 
tors and exhibitors the meeting 
terminated. 
[We regret to have been compelled 
on account of space, considerably to 
contract the report sent us, of the 
above meeting, the more so, as the 
matter omitted was not superfluous, 
but scarcely less important than that 
inserted.]
