Abdomen, not extending beyond the hind wings, attenuated towards the 
tip, slightly tufted on the back. : 
Legs, long, stout, densely pilose, hind tibiæ with long spurs. 
Wings, ample, marginal denticulation obsolete. 
Fore wings: Upper-side slightly concave along the middle of the costa, 
convex towards the tip and base, greyish-dove colour, slightly shot with a 
faint purplish tint, irrorated and clouded with ferruginous and purplish- 
brown scales; transverse lines and central shade purplish-brown; half-line 
angulated ; inner and elbow-lines slightly sinuous and indented, and with 
pale outer margins ; the pale margin of the inner-line rather broad, of the 
elbow-line narrow and vanishing towards the costa ; indentations of elbow- 
line from the costa to the middle forming a profile of a human face; the 
space between the central shade and the elbow-line forming a band darker 
than the ground colour of the wing, but lighter than the transverse lines ; 
the area between the elbow-line and the rather indistinet sub-terminal line 
clouded with ferruginous, interrupted by a purplish-brown shade erossing 
it below the costal area, and forming the upper part into a sub-costal 
patch, the part towards the apex of the angle formed by the costa and 
elbow-line being paler and but slightly suffused with ferruginous ; the 
space between the inner-line and central shade (especially the part beyond 
the middle) paler than the general ground colour ; stigmata obsolete, with 
two dusky specks, one on the upper end and the other on the inner side of 
the lower end of the reniform stigma; hind margin with a narrow dusky 
border and a row of dusky dots. Under-side, basal, third and sub-marginal 
and costal parts pale brownish-grey ; intermediate space dark purplish- 
brown, with a central broad white band extending from the sub-costal 
nervure to the anal angle, and deeply indented at the sub-internomedial 
nervure. 
Hind wings: Upper-side dark purplish-brown, with a median white 
band slightly shaded with pale violet; two white patches on the hind 
margin, the one being sub-quadrate and situated towards the posterior 
angle, the other triangular and situated near the anal angle; also a narrow 
white border extending from the anal angle to near the triangular patch ; 
the white patches extending into the cilia, and slightly tinted with pale 
violet ; clothed at the base with long greyish-dove coloured hairs. Under- 
side pale brownish-grey, a dark purplish-brown patch, with whitish outer 
margin at the anal angle; a transverse narrow dusky fascia crossing the 
middle of the wing, and another beyond the middle, and a very indistinct 
sub-terminal one; an indistinct dusky hunule or spot in the centre of the 
area between the first line and the base of the wing ; two pale patches on 
the hind margin representing the white patches on the upper-side,
