PLATE XXXIV. Fig. 1. 
Pap. Agestis, Ilubner. — Pap. Idas, Lewin, pi. 39. f. 1-2. — 
Donovan, x. pi. 322. f. 2. — Polyom. Idas, Jermyn. — Po-

Expands about an inch, the colour in both sexes 
dark-brown, with a fine silky gloss, all the wings 
having a posterior band of deep red spots, and the 
primary pair a small black spot in the centre : the 
fringe varied with white and brown. The under 
side is greyish-brown, with numerous ocellated spots, 
and a rufous band corresponding to that on the sur- 
face ; the hinder wings with a white blotch on the 
disk. 
Readily distinguished from the females of any of 
the preceding species, by the wings being without 
any tinge of blue, either above or below, and from 
either of the following, by wanting the white spot 
on the disk of the interior pair. It occurs in some 
plenty in Sussex, Kent, Dorset, Somerset, and many 
other parts of England, appearing first in June, and 
again in August.
