 Eindwing with a crimson basal patch and a continuous lengthened streak along the

 with crimson scales ; the four lower submarginal crimsoii lunules and marginal 

 lunules are prominent and broad, the anal pair being partly coalesced ; two upper, 

 or fifth and sixth, smaller white narrow lunules are generally present in the sub-

Habitat. — X.-W. and E. Himalayas. 



Distribution. — Mr. P. "W. Mackinnon found it " rare in Tehri Garhwal, N.-W. 

 Himalaya, in May" (de Xiceville, J. Bombay N. H. Soc. 1898, 593). We possess 

 specimens of both sexes from Garhwal. Mr. H. J. Elwes records it as " a rather 

 rare species in Sikkim, where it is found at from 3000 to 5000 feet elevation, in 

 May and June" (Tr. Ent. Soc. 1888, 42(3). Mr. W. Rothschild has several 

 specimens from Sikkim " (Xov. Zool. ii. 32G).
