PAPTLIONID^. 



"\A"e.st-Himalayan specimens are much whiter than the type, and the Western 

 Chinese form is intermediate between the type and the black Central Chinese 

 form. 



All forms of this species maybe easily distinguished from those of D. bella- 

 donna by the striated rather than round character of the pale markings of 

 both surfaces and by the clubs of the antennae being white or whitish instead 

 of black.

M(de. Black. Costa, inner angle, discoidal cell, and nervular interspaces streaked with grej', the 

 streaks in latter are attenuated towards outer margins, before which they unite with a whitish- 

 centred grey spot, those nearest apex are linear, and the streaks preceding arc not always 

 well defined. Secondaries, inner area of the wings within submedian ncrvure, and a portion 

 of inters])ace above canar}--yellow, each interspace above has a grey streak, those between the 

 median nervules are centred with white, and the upper one is only separated from a broad 

 discal streak by the discocellular nervule ; a series of grey spots before the outer margin, 

 those nearest anal angle with yellow linear centres. Under surface black : primaries with 

 the streaks and spots as above, but white ; the costa is only sprinkled with grey scales ; there 

 are two short yellow dashes between costa and submedian nervure towards apex, and the 

 sjwts nearest apex are more or less yellow : secondaries have canary-yellow markings ; a 

 broad patch at the base intersected by the pnocostal ; a broad streak, whitish towards base, in 

 the discoidal cell; inner area as above; a central and siibmarginal series of spots, but the 

 former are only suffused with yellow to a greater or lesser extent. Fringes grey and 

 black. 



Ffmale. Fuliginous-lilack, tlio costa less grey, the streaks are shorter and are not coniiocted with 



the spots towards outer margin ; the inner area above is whitish towards abdominal fold. 

 Expanse, d 88 millira., $ 92 millim. 



Closely allied to I), helladonna, but at once separated by the -'apparent 

 al)scnce of yellow patch at base of secondaries. There is a yellow dash on 

 the costa of secondaries, but this is of small size, and it is always completely 

 liiddcii by tli(! inner margin of the primaries. 



Occurs at (Jliang-yang, Central China, in June and July.
