Differs from poliaria in the ground-colour of the wings being 

 brownish grey, thickly irrorated with black in fuscescens = irrula ; 

 whilst in the form adusta, from the Nilgiris, the fore wing is almost 

 entirely suffused with brown, leaving some pale specks and a 

 patch at base. Fore wing with traces of anteniedial line, spot at 

 end of cell, and two postmedial lines converging towards inner 

 margin. Hind wing with spot at end of cell and postmedial line. 



The markings become obliterated in the most diffused forms 

 from the Nilgiris, some of which are fuscous in tone and difficult 

 to separate from poliaria, except by the absence of the submarginal 

 line of fore wing.
