Alse supra fuscse; anticce fascia obliqua subcostal! brevi pallida post 

 cellam posita ; corpus {uscum. 



Alae subtus fuscse : antic<B fascia alba triangulari, ad angulum analem 

 coarctata ; cella lineis duabus nigro-fuscis ; margine postico lineis 

 duabus pallidis marginato ocellisque ti'ibus nigris albo pupillatis 

 fulvo, fusco ochreoque circumcinctis submarginato. Posticce lineis 

 duabus mediis super cellam, ad costam approximantibus ; margine 

 postico lineis duabus pallidis marginato ocellisque sex submarginato, 

 primo quintoque majoribus. Alar. exp. unc. If. 



Allied to Dehis Dinarhas, Hewitson, hut front wings compa- 

 ratively shorter; hind wings shorter; costa suddenly arched 

 above the apical ocellus ; outer margin much more rounded ; cen- 

 tral caudal projection almost obsolete ; inner margin proportion- 

 ably much longer. 



In coloration and markings it differs as follows : — Upperside, 

 front wings with only one pale, oblique, transverse band, two- 

 thirds distant from the base ; hind wings not showing submar- 

 ginal ocelli. Underside olivaceous, instead of reddish brown : 

 front wings, transverse band broad at the costa, dirty white, 

 tapering to near the anal angle ; subapical ocelli distinct ; sub- 

 marginal lines not waved : hind wings, central portion broad in 

 the middle as in Dehis Ghandica, Moore ; submarginal ocelli 

 slightly larger, the one at the anal angle unequally bipupillate.
