and also on each side of the centre ; abdomen orange-yellow, 



with a very broad black stripe down the back, tapering off a 



little to the anal segment. Fore wings rather triangular, 



narrow at the base, not very broad behind, with the costal 



and dorsal margins nearly straight, the apex very slightly 



angulated, and the hind margin gently rounded and rather 



oblique; black-brown with creamy white stripes and blotches, 



of which a long straight stripe proceeds from the base, 



parallel with the dorsal margin, nearly to the anal angle, 



becoming forked at its extremity ; a short wedge-shaped 



blotch lies on the base of the costa ; beyond it is a larger and 



more reniform spot touching the costa, or in some cases 



detached and roundish-ovate or pear-shaped ; still beyond is a 



stripe crossing from the costa to the anal angle rather 



obliquely, and itself crossed by another stripe arising near 



the apex of the wing, making a wide elbow before it crosses, 



and very often proceeding to join the upper fork of the 



straight dorsal stripe; cilia extremely short, creamy white. 



Hind wings with the apex and hind margin regularly rounded ; 



light yellow with black stripes and spots — one black stripe 



from the middle of the base makes a broad elbow in the 



middle of the wing by uniting with a large irregular central 



spot ; another from the base near the dorsal margin attains 



the anal angle ; round the hind margin is a series of black 



blotches forming a broken sub-marginal band, inside which 



are two or three large black spots ; cilia yellow. 



Female similar in size and shape of wings, and mainly so in 

 markings, but with much stouter abdomen ; the pale stripe of 

 the fore wings more yellow, sometimes reddish in the costal 

 area ; hind wings yellow, with the black stripes from the base 

 expanded and joined together, so that a great black blotch 

 occupies the basal half of the wings ; the sides of the abdomen 

 sometimes bright red. 



Underside similar to the upper, but with the dark markings 

 of the wings hardly so sharply defined, and the colour of the 

 paler portions more yellow or even tinged with reddish ;
