c?. Upperside: Avhite. Fore wing: veins black, edged broadly 

 with the same colour towards the terminal margin, the black con- 

 tinuous along the actual margin, in the interspaces above vein 3 

 it is densely irrorated with black scaless and leaves mere narrow 

 streaks of the white ground-colour apparent ; costa black. Hind 

 wing : the yellow ground-colour of the underside partially visible 

 through transparency ; veins 7 and 8 black, the rest black only 

 towards their apices ; finally, a black terminal slender line. Under- 

 side : fore wing white, the veins broadly edged with black, this colour 

 dilated broadly along the discocellulars, along the basal halves of 

 veins 3 to 7, along the costa, the apex of the wing and at the ends 

 of all the veins. Hind wing : yellow, precostal area vermilion-red r 

 all the veins jet-black and prominent; a subterminal comparatively 

 broad band from apex of vein 3 to apex of vein 7 white, narrowed 

 posteriorly : beyond it a narrow terminal edging of black. An- 

 tennae and head black, thorax clothed with long bluish-grey hairs, 

 abdomen white ; beneath : the palpi and thorax dusky-black, 

 abdomen white. $ . Upperside : as in the J , but on the fore wing 

 the black edging to the veins greatly increased and the ground- 

 colour limited further by a very dense irroration of black scales, 

 which gives a dusky-grey appearance to so much of the white as 

 is visible ; thus the wing looks all black, with a series of very 

 diffusely-defined greyish streaks in the cell and interspaces beyond, 

 which streaks, however, do not attain the extreme margin and are, 

 moreover, more or less medially interrupted by the black and form 

 an obscure discal and a subtermirial series. The whitest spots 

 left are the elongate ones in the cell and in the anterior inter- 

 spaces beyond and above it. Hind wing : the black terminal line 

 in the c? replaced by a broad black terminal band traversed by a 

 series of spots of the white ground-colour in the interspaces ; 

 these, however, are thickly overlaid by an irroration of black 

 scales. Underside : fore wing similar to the upperside, but the 

 streaks and spots of the ground-colour left apparent are not so 

 densely overlaid with black scales. Hind wing as in the c? , but 

 the black edging to the veins very much broader ; the subterminal 

 band black, with an anterior series of large yellow spots, and 

 divided from the yellow over the basal and discal areas by a 

 curved subterminal narrow black band ; the terminal spots, as in 

 the d , do not reach below vein 2 ; in most specimens the one or 

 two posterior spots are pale, inclining to buff orochraceous white. 

 Antenna} black ; head, thorax and abdomen nearly black, much 

 darker than in the c? -
