TRIFID^E. 8 1 



anal tuft long and narrow but rather forked, -brownish-white. 

 Fore wings rather narrow but broader behind, of singular 

 beauty ; costa straight to beyond the middle, then much 

 arched ; apex bluntly angulated ; hind margin oblique, 

 almost straight ; dorsal margin very straight ; colour silvery- 

 white flushed with purple, very much marbled with black 

 and black-brown ; basal line indicated by short black streaks 

 and spots ; first line a double series of deep black clouded 

 crescents which form a conspicuous double bar across the 

 wing ; second line greyish-white, arising on the dorsal margin 

 as a twice angulated streak edged on each side with black- 

 brown clouding, hardly perceptible in the middle portion, 

 though faintly edged in the same manner, more distinct 

 again toward the costa ; orbicular stigma curiously indicated 

 as a white space enclosing two black spots placed perpendicu- 

 larly, and margined at the corners by four more ; reniform 

 stigma more obscurely white but similai^ly centred and 

 cornered with black spots ; between these stigmata is a 

 series of deep black clouds, forming a central stripe which 

 unites with the black clouding before the dorsal part of the 

 second line, and so takes the place of a central shade ; space 

 outside this dappled with faint elongated cloudy-brown 

 streaks, more blackened toward the apex ; hind margin 

 edged with a row of large black dots; cilia silvery- white, 

 twice intersected by pale purplish-grey lines. Hind wings 

 rounded, but with a slight angle in the hind margin ; white 

 at the base, shading off to smoky-brown at the apex and 

 behind ; nervures pale brown ; cilia white. Female very 

 similar but with a shorter abdomen. 



Underside of the fore wings pale smoky-grey, dotted on 

 the costa and hind margin with white. Hind wings white* 

 shaded with smoky-grey along the apical and hind-marginal 

 regions ; cilia white. Body and legs whitish-grey. 



Usually very constant in colour and markings, merely 

 varying in the extent of black spotting and bands ; but in 

 the collection of Colonel Partridge is an ashy-white example
