 cilia light grey, becoming pale yellowish on upper part of termen. 



Maskeliya, Peradeniya, Ceylon (Pole, Green, de Mowbray) ; from February

 special character. I have a large $ specimen, in which the whole forewing is 

 suffused with rather dark fuscous, except a yellow streak on costa posteriorly, 

 the cilia yellow as usual ; it is probably a variety of this species ; in colouring 

 it recalls melicrossa, but is not so dark, and differs in palpi and form of wing.
