364 LEPIDOPTERA. 



and anal tufts spreading, silky-white. Fore wings rather 

 narrow, pointed, and slightly retuse; costa gently arched, 

 more so towards the apex, which is acutely angulated ; hind 

 margin below it faintly hollowed to beneath the middle and 

 hardly oblique, then rounded off ; dorsal margin straight or 

 very faintly concave ; colour clear pale yellow ; towards the 

 base are two or three cloudy purple-red spots or blotches, the 

 inner edge of which represents the basal line ; just beyond 

 them is the first line, very slender, partial, and broken into 

 two faint curves, purple-red ; second line not very oblique, 

 composed of a series of short purple-red crescents, the upper 

 thickened, the lower duplicated outside but much obscured 

 by large clouds of the same colour, which form a roughly 

 angulated central shade or band, and are extended outward 

 interruptedly on the costal half of the wing to near the 

 apex ; subterminal line a row of distinct purple-red dots, 

 sometimes followed by a partial parallel row of similar but 

 more cloudy dots ; orbicular stigma rather small, round, a 

 mere ring of purple-red, and often absent ; reniform stigma 

 obscured in the clouds of the central band, faintly margined 

 above, the lower portion occupied by a blue-black spot ; cilia 

 yellow dashed and edged with purple. Hind wings clear 

 white, with a brownish gloss towards the dorsal margin ; 

 cilia pure white. Female quite similar, but with the abdomen 

 stouter and shorter but more pointed. 



Underside of the fore wings yellowish- white, with a small 

 purplish-red streak and cloud from the costa beyond the 

 middle ; cilia purple-red. Hind wings clear yellowish-white. 

 Body and leg-tufts pale yellow, legs purple-red. 

 c Very variable in the extent and intensity of the purple 

 clouds of the central band, which sometimes are extremely 

 dark, in other cases pale purplish-pink and very obscure, or 

 reduced to a few fine lines and dapplings, while in other 

 instances the wing is to a great extent filled up with paler 

 or darker clouding. A distinct variation in the ground 

 eblour to ochreous or orange-yellow is not infrequent in ^
