Polyommatus Agestis. 



PLATE XXXIV. Fig. 1. 



Pap. Agestis, Hubner — Pap. Idas, Lewin, pi. 39. f. 1-2 — 

 Donovan, x. pi. 322. f. 2 — Polyom. Idas, Jermyn. — Po- 

 ly om. agestis, Stephens. 



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.
