c?. Upperside: dusky brownish-black. Fore wing : the ground- 

 colour darker, almost pure black in fresh specimens, on the apical 

 third of the wing; a short streak in the middle of interspace 1, a 

 more outwardly produced similar streak in interspace 2, basal halves 

 of interspaces 3 and 4, the lower apex of the discoidal cell and the 

 extreme base of interspace 5, white, all forming a median con- 

 spicuous irregular white patch on the wing, narrowly traversed 

 by the veins which are greyish-brown. Hind wing : more uniform, 

 slightly darker on its anterior half. Underside : light brown with 

 an ochraceous tint. Fore wing : the median white patch as on 

 the upperside but larger, its margins less clearly denned, continued 

 posteriorly to the dorsal margin ; obscure catenulated, incomplete, 

 transverse, white-margined narrow bands, two at base and two 

 or three very short ones above the white median patch on the 

 costal area ; from between the outer two of these latter a trans- 

 verse, zigzag, very slender, somewhat obscure white line crosses 

 the anterior portion of the wing to vein 4 ; lastly a pretornal 

 quadrate brown spot near apex of interspace 1 a and an obscure 

 subterminal transverse series of slightlv lunular small brown spots ; 

 the ground-colour terminally paler and more ochraceous than on 

 the inner portions of the wing. Hind wing: crossed by very 

 obscure sinuous brown and white slender lines, that on the costal 

 area form very short, obsolescent, catenulated narrow brown bands ; 

 a subterminal series of brown slender lunules, sometimes obsolete. 

 Antennae, head, thorax and abdomen brown ; beneath : paler, the 

 palpi and thorax more or less white. $ . Upperside. Fore wing : 

 dark brown ; base shaded with greyish brown ; the white median 

 patch as in the c?, but very much larger, its upper margin 

 irregularly curved ; it is spread over the anterior two-thirds of 

 the ceil, extends beyond it into the bases of interspaces 4, 5 and 6, 

 and below the cell it occupies the basal four-fifths of interspaces 

 1 and 2. Hind wing : costal margin broadly dark brownish ; 

 wing posteriorly from below the subcostal vein and vein 6 a 

 beautiful pale bluish-grey ; a broad whitish streak beyond the cell 

 not reaching the termen. Underside, fore wing : the median 

 white patch as on the upperside but larger, extending to the dorsal 

 margin and base of cell ; base of wing, costal margin above the 

 subcostal vein and conjoined upper discal obliquely-placed patch 

 greyish brown ; apex of wing whitish, termen between veins 1 

 and 6 broadly stained with rusty ; a conspicuous rusty pretornal 

 spot ; some obscure white-margined spots at base of cell and along 

 costa, and a trans verse subterminal series of black dots. Hind wing : 

 pale ochraceous white, darkening to rusty brown towards the middle 

 of the termen ; a subbasal, a median and a discal transverse
