irroration, on apical half with faint whitish-fuscous irroration. Hindwings 

 grey ; cilia whitish-ochreous, tinged with fuscous. 



Fifteen specimens, Peradeniya and Madulsima, Ceylon, from February to 

 April (Green, Vaughan). Larva feeding in galleries several inches long on 

 surface of moss-covered rocks, and pupating in an enlarged chamber (Green) ; 

 specimens of these galleries sent by Mr. Green are composed of silk covered 

 with grains of sand and fragments of lichen, moss, and incidental refuse ; from 

 similar undistinguished galleries two other species of different genera were also 

 bred. Not only is this species very close to E. authcema as noted above, but 

 also by its obscure and ordinary colouring exceedingly similar superficially to 

 species of other genera, from which it must* be carefully distinguished by 

 verifying the neuration.
