numbers, and had no difficulty in selecting some sixty specimens in 
a couple of hours in the morning. This brood was apparently con- 
fined to one large rough field, as in the afternoon we explored other 
parts of the woods where the spring brood has been abundant 
without seeing a single selene. On the 11th there seemed to be a 
still greater number on the wing. On neither occasion did I notice 
any varieties, but I believe some were takep subsequently by local 
collectors. Mr. Sharp tells me that the spring brood was out in 
great numbers between May 23rd and June 6th. It seems possible 
that as June and July were cold and wet the vegetation would 
receive no check to its growth as in hot and dry summers, when 
previous second broods have been recorded, and this may account 
for the large number of this 1920 August emergence. Looking back 
through various magazines I can only find records of one or two at a 
time, except in 1911, when 30 were recorded from Ufracombe.—H.

Conmias Epusa AND AaB. Hrenice.—The experience of friends of 
myself in this district this season with these insects may be of 
interest. On August 8th, after an absence of three years, I first saw 
edusa at Halland, near Uckfield, Sussex, and later in this district I 
saw about twelve, of which I secured three gcod specimens, one 9°. 
On returning to Brighton on August 13th. I renewed my search, and 
from that date to the end of September I saw altogether about thirty- 
six, of which I secured twenty. On September 5th I obtained three 
worn 9, and decided to see if ova were produced, and during the 
next fortnight I was successful in obtaining a goodly number, but 
many were not fertile. Altogether about three dozen hatched, of 
which I retained one-third and g gave the others to friends. From 
October 20th mine pupated, and at the present time of the whole 
number sixteen have emerged, the first on November 11th, one being 
ab. helice, and the last yesterday, a 9. I still have three pupz 
which are changing and should emerge this week. At first the 
larvee were fed on °M. sativa, but later the food was changed to 
L. corniculatus, which they took more readily to. Friends of mine 
saw many edusa in this district during August and September, one 
securing so many as nine dozen. Altogether, including the one 
referred to, there have been eleven ab. helice taken this season in the 
neighbourhood of Brighton.—Louts Mrapren; Melbourne, Dyke 
Road, Preston, Brighton, November 19th, 1920. 
[Since sending the above note, Mr. Meaden reports two other 
specimens of helice reared by friends from larve he had given to 
them.— Ep. | 
Couias EDUSA, PYRAMEIS ATALANTA AND AGLAIS URTICH IN 
CAMBRIDGESHIRE, GUERNSEY, AND NortHerN FRANcE.—The following 
notes may have some interest in connection with those which have 
recently appeared in the ‘Entomologist.’ The only Colias that I 
have seen in England this year was one specimen of C. edusa flying 
beside the Newmarket Road, about four miles from Cambridge, on 
August 26th. Inquiries made of several naturalist friends have not 
produced any other evidence of this butterfly being seen in the district 
this season. Mr. Michael G. L. Perkins tells me that it was abun-
