THE LEPIDOPTERA OF ESSEX. 85
ii. 182). One, Colchester, Aug., 1858 (Harwood ; E.W.I. iv. 194).
One, Colchester, end of Sept., 1865 (Harwood ; Proc. E.S.L. 2nd
Oct., 1865). One, Colchester Aug. 15th, 1868 (Harwood;
E.M.M. v. 106 ; Ent. iv. 146). Another, Colchester, Sept., 1868 (Har-
wood ; E.M.M. v. 131 ; Ent. iv. 161). "I have taken four in different
years in the neighbourhood of Colchester, and have seen three others
taken, two of them by one of my brothers ; Mr. W. Harrington and
Mr. Robert Halls have each taken single specimens ; others have
been taken at Berechurch by the late Dr. Maclean and Mr. Law-
rence Black" [should be Brock] (Harwood ; B.B. 34). One, St.
Osyth, Sept. 14th, 1881 (Harwood ; Ent. xiv. 232). One, Brain-
tree, Sept. 19th, 1865 (B. Holland ; Ent. ii. 311). Three, South-
end, 1868 (J. Russell ; Ent. iv. 160). One, Rainham, Oct., 1870
(F. Venables ; Ent. v. 212). Near Sudbury (Gaze ; Z. xx. 7971).
"Said to have been once taken on the Newton Road, Sudbury"
(W. D. King ? ; F.S.J. Dec., 1838).
This rare species has also been taken at Stoke-by-Nayland
(Jermyn ; V.M. 67) and Felixstowe (Ent. vi. 192), just over the
Suffolk border.
Argynnis aglaia, L. Dark-green Fritillary.
Geographical Distribution—Europe, North, West, and East Asia. Common on
the Continent, but local in Britain.
Larva—Greyish-back, double yellow line on back, orange-red spots on sides ;
spines black. Food—Dog violet. Imago—June to August ; hibernates as larva.
Rare ; on commons, heaths, and rough hill-sides. Local and
apparently disappearing from the county.
Lexden Heath, Birch Wood, near Dedham, Bromley Thickets,
Wrabness Cliff (Jermyn ; V.M. 67). Southend (Harwood ; B.B.
28) [doubtful?]. Sudbury (J. Grubb ; B.B. 29). I once saw a
large Fritillary at Colne Point, St. Osyth, which I believe was this
species ; it might have been A. lathonia (Fitch). Woods near Bergholt,
over fifty years ago (H. Doubleday, in letter to W. H. Harwood).
Argynnis adippe, L. High-brown Fritillary.
Geographical Distribution—Europe (except polar regions), Asia (probably to
China and Japan). Absent from Scotland and Ireland.
Larva—Reddish-ochreous, interrupted whitish lines on back, velvety-black
transverse streaks along sides ; spines rusty brown. Food—Violet and heartsease.
Imago—July ; hibernates as larva. From Buckler's "Larvae" this seems doubtful ;
he had eggs laid Aug. 25th, 1877 ; hatched, March, 1878 ; and again eggs laid
Aug. 7th, 1882 ; hatched Feb. 14th, 1883.
