NOTES OF OBSERVATIONS

expenses of harvesting. The Beetles are noted as appearing first on 
the Mustard, hut will also attack young Rape, and Mangolds in full 
leaf when growing near infested Mustard plants. A specimen of 
Mustard was forwarded, showing the eggs had been deposited in slits 
in the leaves close to the main ribs, and many holes had been eaten in 
the substance of the leaf by the perfect insects. Mr. Burgess mentions 
that in a dry season he has never observed these Beetles, but in 
showery weather they are very destructive, and at harvesting time 
may be found in almost incredible quantities on the crop. A severe 
storm of rain and hail appears to have been in this case the most 
efficacious remedy, though rather unfortunately neutralising the effect 
of a careful series of experiments as to the effects of various applica¬ 
tions. In the Cabbage-growing district round Isleworth it is considered 
that fresh hops from the brewery are a very good means of keeping 
off the ordinary Turnip Fly, and the application might possibly have 
a good effect on the allied Chrysomelideous Beetle, P. betula:. 
COLTAS EdUSA. 
Colias Edusa. Clouded Yellow Butterfly. Mr. Norgate 
mentions seeing a female on September 3rd at Brockenliurst, in the 
New Forest; and at Tangley, Guildford, it is mentioned as “scarce 
as usual.” At Maldon a single much-worn specimen w T as seen by 
Mr. Fitch on September 26tli. Mr. E. Parfitt mentions not having 
seen and only having heard of one specimen near Exeter this season. 
At Sedbury Park, West Gloucestershire, however, the Clouded Yellow 
is reported as having been seen in some numbers about September 
29th, and the particulars forwarded, on special enquiry being made, 
left no doubt as to its having been this Butterfly. This observation 
of the continuance in the neighbourhood is of some interest, for in 
1859 there was a sudden appearance of the Colias Edusa in such great 
numbers on one Clover field, at Sedbury Park, that I might have 
taken them readily in dozens; and although the Butterfly was very 
rare (or, I believe, unknown in the neighbourhood previously), I saw
