taken there. I took one specimen, and saw two others, on April 18th, 1891 ; 
and I find it recorded also in the ‘ Naturalist,’ March, 1887, as having been 
taken there by F. N. P.; vide also Dr. Ellis’ list of ‘ Lancashire and 
Cheshire Lepidoptera,’ p. 49. I have seen it there again this year.—

Larva or TortTriIx VIRIDANA UNUSUALLY ABUNDANT.—The oak trees 
in Windsor Forest are now experiencing a very severe attack of the Tortrix 
viridana. It appears that every year this moth is present in some numbers, 
but this season it is exceptionally abundant. ‘The trees are completely 
stripped of their leaves, giving the forest a very weird and wintry 
appearance. ‘The beech and hawthorn, which occur scattered about amongst 
the oak, are not attacked, and form pleasant breaks in the otherwise dreary 
aspect of the wood. A week or two ago the larve were seen hanging in 
millions from the trees suspended by their fine silken threads. They have 
now, for the most part, changed into the pupal state, and the advanced guard 
of the imagos is appearing. Birds are by no means as numerous as might 
be expected. Some rooks, starlings, and titmice were noticed. It might, 
perhaps, be mentioned that these oaks were planted somewhere about the 
beginning of this century, to provide timber for the royal navy. On the 
introduction of the ironclad, the forest seems to have become more and 
more neglected. Ought not some attention to be drawn to this fact, as it 
must be injuring what would otherwise be a valuable timber forest ?—E. P.

DELAMERE Forest Forms ov HyBmRNIA LEUCOPHEARIA.—I am in- 
debted to Mr. South for the following comment on the four forms of this 
insect, described in my ‘‘ Notes on the Early Moths ” (see Entom. for May 
and June):— Your form I. is typical; III., var. marmorinaria, Esp. ; 
II. is intermediate; and IV. isa parallel variety with that of H. marginaria 
( progemmaria) var. fuscata.”—J. ARKLE; Chester. 
PLUSIA GAMMA AND VANESSA CARDUI AT CHESTER.—These insects are 
extraordinarily abundant just now in the Chester district, and have been 
so since the beginning of June. LP. gamma is a complete nuisance when 
netting moths in the evening. I wonder if they appear as heralds of an 
“‘edusa year” !—J. ARKLE; Chester, June 18, 1892. 
Karty Lepmorrrera in Yorxsurre.—Hybernia rupicapraria and H. 
marginaria have not been so common this season in the neighbourhood of 
York; but from amongst a number of specimens of H. marginaria I have 
been able to select some very pretty forms connecting fuscata with the type ; 
a very pretty form, which occurs sparsely, is that with a broad black border 
to the fore wings. It is rather singular that the fuscata form has become 
much commoner of late years; some ten years ago it was quite unusual 
to find aspecimen; now it occurs almost as commonly as the type. Doubt- 
less the very cold, wet, and sunless summers that we have had during the 
past few years have had something to do with it. I have also taken speci- 
mens of H. leucophearia, including the variety marmorinaria, Esp., L. 
multistrigaria, and A. @scularia.—WILLIAM Hewett; Howard St., York. 
CoLias EDUSA IN 1892.— 
Worcestershire. —I have pleasure in recording the appearance of 
Colias edusa at Worcester during the present month. One worn female 
was caught by a boy near here, and brought to me for identification ; 
another was seen by a friend at Monkwood; and two more I saw flying
