164 THE BUTTERFLY VIVARIUM. 



Plate (No. 8), is one of the largest of our Blue 

 Butterflies, and one of the most distinct in colour — 

 the hlue being almost entirely subdued about the 

 middle of the wings by a metallic gloss of silvery 

 white, verging on pale straw-colour ; while at the 

 borders all four wings become nearly black, with a 

 border of still deeper-coloured dusky spots. The 

 female is deep brown, having an orange border with 

 black spots at the edge of the hind-wings, and in 

 the centre of all four wings a speck of white. 



The small chrysalis of this species is shown 

 lying on the ground (No. 5), immediately beneath 

 the White Butterfly ; but it is said to be generally 

 found attached to the wild tbyme.
