NOTES AND OBSERVATIONS. 147 
usually are about the middle of May. Yesterday I saw a horse- 
chestnut in full bloom. This tree is always a fortnight or three 
weeks earlier than others growing near it—why, it is impossible to 
say, unless, perhaps, its roots may be near some warm spring. 
Preris rape and ‘P. napi are not as numerous as they were this time 
last year. I saw the first on March 25th, but they were probably 
out before this. P. brassice I have not yet seen, but last year I saw 
one on .March 20th, which I think is a pretty early record. Two 
Smerinthus ocellatus were seen ‘“ paired” on a post on April 9th—a 
very early appearance. Several Chrysophanus phi@as were flying 
about the railway bank near Dovercourt Station on the 10th, and 
Phlogophora meticulosa was noticed sitting on a fence on the 11th. 
On March 22nd I visited Stour Wood for a few hours where I saw 
several Brephos parthenias flying round the young birch trees, and 
D. fagella was plentiful on the oaks—six or seven often close together 
on one tree, and there were some nice varieties. Larve of Arctra 
villica are about a month earlier than last year. I took the first full- 
grown on March 15th and continued to find them up to the 12th 
instant, aud have now a good number. They commenced to spin up 
on March 27th, and more than half are already in the pupa state. I 
hope I may breed some good varieties.—GERVASE iF MatHEw; Lee 
House, Dovercourt, April 13th, 1921. 
Earuy Leriorrera.—Pieris rape and Aglais urtice were seen 
flying on March 24th, and a male Huchloé cardamines was taken on 
the 25th. On April 9th Celastrina argrolus was noted at Hove, and 
two specimens of Phlogophora meticulosa were captured. Specimens 
of Xanthorhoé unangulata were seen and a female netted on April 
12th, and on the 13th of that month a female Phragmatobia 
fuliginosa was secured.—F. G. $8. Bramweti; 1, Dyke Road Drive, 
Brighton. 
PYRAMEIS ATALANTA IN Marcu.—On March 26th last I noted a 
specimen of P. atalanta at Bookham Common. There seems no 
doubt that it had hibernated here.—R. N. Goopman, M.S.; Kingston- 
on-Thames. 
RETARDED DEVELOPMENT OF C@NONYMPHA TIPHON.—In the 
March number of the ‘Entomologist’ for the year 1920, vol. liu, p. 66, 
I recorded the retarded development of five larve of this species. 
Although three of these lived through their second winter only one 
finally survived to pupate; this took place at the end of May, 1920, 
and produced a perfect female butterfly on June 16th, 1920. The 
larval state occupied 21 months 2 weeks. The complete metamor- 
phosis extended from the middle of August, 1918, to the middle of 
June, 1920.—F. W. FroHAwkK. 
Harty APPEARANCE OF CELASTRINA ARGIOLUS AND PImRIS BRASSICE. 
On March 24th last I saw/a male Celastrina argiolus on the wing, 
this is the earliest date I know of for this species to make its 
appearance. At the same moment a male Gonepteryx rhamni and an 
Aglais urtice were flying over and feeding on dandelion flowers. 
On April lst Pieris rape appeared and on the following day I saw 
P. brassicé on the wing, which is a very early date for the latter. 
The weather on all three days alluded to was fine with cloudless
