THE upper surface of the wings is of a fine deep 

 straw yellow. Upper wings long, in proportion to 

 the under ones ; their whole exterior margins are 

 furnished with a broad black border, near the outer 

 edge of which is a double row of longitudinal spots 

 of the same colour as the wings, within which, 

 on the upper wings, are corresponding fasciculi of 

 small dots. Towards the external margin are two 

 large oblong patches of black, in the middle of which 

 are blotches of azure blue. Under wings, consider- 

 ably indented ; in place of the bundles of dots, are 

 corresponding blotches of azure blue ; and at the 

 anterior angle of the lower wing, on the border, is a 

 scarlet circular spot. Under wings, bushy. 



The body is black, blue in the centre, having a 

 longitudinal central line, extending nearly to the 

 point of the tail.
