Underside buff, darker at inner margin of hind-wing; in cera- 

 mensis the ground-colour is white. Fore-wing with outer margin 

 broadly smoky-brown, narrowing posteriorly and traversed by a 

 thin line of ground-colour which becomes obscured anteriorly; a 

 deep brown triangular costal patch, its apex directed outwards 

 below vein 2; this patch is narrower in ceramensis and reaches 

 lower submedian. Hind-wing with a narrow smoky-brown margin 

 from apex to vein 3, and a faint smoky line running parallel to it; 

 rest of margin yellow and proximally bordered by a black line edged 

 with metallic blue; an admarginal whitish line from lc-i; a round 

 black spot bearing some metallic blue scales in its upper part, in 

 the marginal yellow in 2; next this an oblong metallic blue spot, 

 round in the typical form, is placed oblicpiely in lc; anal lobe as 

 in allied species; a dark-brown discal and inner-marginal band, 

 as in ceramensis but broader. Thorax above chestnut-brown, 

 abdomen rufous. 



§. Upperside similar to despoena, Hew. Fore-wing with blue 

 area extending just beyond the white patch, its outer edge evenly 

 curved and parallel to margin. Hind-wing with more extended 

 blue than in despoena and only a faint whitish scaling on costal 

 area. 



Underside similar to the allied species. Fore-wing darker at the 

 base; costal patch extended to 16. Hind-wing darker at base; 

 ochreous marginal patch in 3 bearing a black spot with a blue centre ;

 Ribbe. 



$. Smaller than allied forms. Upperside paler than in neopom- 

 merana; costa, apical area, and cell of fore-wing darker; anal lobe 

 brick-red and bearing a small dark central spot. 



Underside grey and paler than in the allied species. On the 

 hind-wing the inner edge of the spot in 7 is in line with the inner 

 edge of the two discal spots, forming a line, broken in cellule 2, 

 from costa to inner margin. Anal lobe black, eye-spot in 2 black 

 ringed with pale yellow, a slight bluish scaling between it and inner 

 margin. Abdomen below pale yellow.
