either fusiform in shape, or broadest at their lower ends, the inner portion being 
the shortest, and in some specimens an outer or upper fourth portion is also 
present, which latter is also small and more or less rounded and speckled with black 
scales, the three lower portions also being posteriorly edged with crimson scales; 
beyond are either four, or five, submarginal narrow crimson lunules, the upper one, 
when present, being almost white; below them are four marginal smaller crimson 
lunules edged with white cilia, the cilia of the upper incisions being also white ; in 
some specimens the submarginal lunules are more or less obsolescent or partly 
obsolete ; tail duplex-spot pale crimson or whitish, small, sometimes obsolescent. 
Underside. Both wings paler. Forewing with a crimson patch at the base. 
Hindwing with a crimson basal patch and a continuous lengthened streak along the 
interspace between the median and submedian ; the discal white patch as above, the 
two inner portions slightly speckled with crimson scales externally, or each is so 
speckled at both ends, and in some specimens the inner portion is entirely covered 
with crimson scales; the four lower submarginal crimson 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¬ 
costal interspaces, and sometimes even a minute seventh in the costal intersjrace. 
Female. Upperside somewhat paler. Forewing wnth a small crimson basal 
cell spot. Hindwing with the discal white patch composed of three nearly equal

Habitat. —N.-W. and E. Himalayas. 
Distribution. —Mr. P. W. Mackinnon found it ‘ e rare in Tehri G-arhwal, U.-W. 
Himalaya, in May ” (de Hiceville, J. Bombay H. 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, 426). Mr. W. Rothschild has several 
specimens from Sikkim ” (Uov. Zool. ii. 326).
