barred with fuscous, terminal with an interrupted pale gr eyish antemedian 
shade. Hind wing white, faintly suffused and dotted with ochreous-greyish 
towards apex and costa, cilia white with a faint greyish antemedian line. 
Genitalia very similar to those of marmorata, except shape of transtilla : 
median projection slender, longer than in that species, its stalk shorter 
(shorter than the projection itself), much smaller, narrowed in middle 
(Slide No. 387 D, holotype). 
Mis t Camp, 1800 m, January 11, 1939. One specimen. Allied to marmo-
