trated sunshine which there glows with an unsubdued heat 

 such as the race of butterflies rejoices in. 



The caterpillar feeds on the milk-vetch, f Astragalus cicer.) 



The expanse of the wings is between three-quarters of an 

 inch and an inch. The upper surface of the fore wings is 

 obscure dark brown, more or less glossed with blue, chiefly 

 at the base. The hind wings are likewise of a dull dark brown 

 colour. The fringe of the wings is white. 



Underneath, the fore wings are of a pale silvery ash-colour, 

 with a small black dot near the front edge, and between this 

 and the hind margin is a transverse row of small black spots 

 with white rims, the two lower being more confluent. The 

 hind wings, which are of the like ground colour, have three 

 or four of the eyed spots irregularly placed on their inner 

 part, beyond the middle of which is a waved row of seven or 

 eight similar spots, and on the margin is a black spot near 

 the lower corner. 



The female is duller in colour than the male. 



The caterpillar is green, with yellow lines on the sides and 

 the back. 



The figures are from one in my own cabinet, and from others 

 in that of Mr. Allis, of Osbaldwick, near York.
