Ijiago. — Male. Upperside paler oclireous than in A. Ganga, -with similar 

 markings, except that on the forewing the pale interspaces are more defined and 

 unsullied, and on the hindwing having the discal and submarginal black band 

 contiguous, the submarginal also being disposed further from the marginal, and the 

 discal is somewhat narrower and disposed further from the subbasal. Underside 

 also paler than in ^. Ganga ; markings similar, except that on the hindwing the 

 two median lunular bands are more contiguous and are more distinctly dentate. 



Female. Upperside ochreous brownish-black ; markings similar to female 

 A. Ganga, but of a yellowish-ochreous colour and comparatively broader. Underside 

 similar, except that on the forewing the two large costal pale lunules are both 

 yellow, and on the hindwing the two medial bands are more contiguous and also 

 moi-e distinctly dentate. 



Expanse, <? 3,;^, ? S^-q to S^-q inches. 



Habitat. — Sikkim ; Bhotan. 



DiSTRiBDTrON. — "Both this species and the preceding occur together in Sikkim 

 at low elevations from May to August, but are by no means common, and appear to 

 be confined to Sikkim " (de Xiceville, Sikkim Gazetteer, 189J., 142). Mr. G. C. 

 Dudgeon has taken it in Bhotan. 



Habits. — " In the habit of resting with wide outspread wings on leaves in dense 

 forest, they closely resemble many species of Euthalia " (de Niceville, Butt. India, 

 ii. p. 183).
