pink or grey, especially along the hind margins. 4. The hind 
margins are much more indented in the female of this species 
than in that of Iris. Lastly, the clubs of the antennfe are tipped 
with yellow or orange. PI. XXXV., 1. 
Times of Appearance. — June and July. 
Habitat. — Part of Central Europe (including Germany, 
Switzerland and France), also a part of Northern Asia and 
Armenia . 
Larva. — Very similar to that of Iris, but somewhat smaller 
and of a yellower colour, except on the ventral surface. The 
cephalic horns are bordered with yellow. 
PuPA.^ — Somewhat rounder than that of Iris, and less pointed 
anteriorly. 
The larva is found in May, and feeds on Sallow and on 
several kinds of Poplar, chiefly Fopuhis alha. PI. XXXVI., 3 (from

a. Clytie, Schiff. S. V. p. 321; Hiih. 113-4; Err. B. 2,1.— Iris 
Jhihcscens, Esq. 71, 2, 3. — Astasia, Htib. 812-3. This is the usual 
form of the species in some parts of Europe, the typical form only 
occurring occasionally ; it is smaller than the type and has the 
white fascia and spots replaced by yellow or orange ; sometimes 
the ground colour is entirely orange as in the female specimen, 
figured (PI. XXXV., 2). This specimen was taken on the shores 
of Lago Maggiore, where this extremely light form seems to be 
constant in the autumn brood. 
Habitat much more extended than that of the type ; Germany, 
Switzerland, France, North Italy, Finland, and Eastern and South- 
Eastern Europe. It is double-brooded in the South. The imago 
occurring in June and the end of August. 
h. Metis, Err. B. 67, 1, ii. p. 61 ; H.-S. 539-41. Rather like 
Clytie, hut the fore wings have their hind margins more deeply 
concave, and tlie hind wings more indented. The ocellated spot 
of the hind wing is altogether wanting. 
Habitat. — South-East Russia. (Sarepta). PL XXXV., 3.
