Occurs in Western China at Omei-shan, Chia-ting-fu, and Chia-kou-ho. 
Except that they are rather larger, Chinese specimens are identical with 
those from Sikkim and exhibit the same range of variation. The primaries 
are sometimes traversed by a series of subdiaphanous white spots extending 
from costa to inner margin. In a few specimens the black spots on 
lower two thirds of submarginal area of secondaries are Avell separated 
and clearly defined, but usually the spots are confluent and form a broad 
submarginal band. 
Elwes says that the species occurs all along the Himalayas and is found in 
Sikkim up to 4000 feet, from March to December. In the Malay Peninsula 
it is represented by a form which Butler has named calligana (Trans. Linn. 
Soc. (2), Zool. i. p. 556, pi. Ixix. fig. 11 ; Distant, Rhop. Malay, p. 387, 
pi. xxxiv. fig. 6.)

" Fore wing narrow, elongated ; costa arched at base, then straight to apex ; apex acute ; outer 
margin at right angles to costa from apex to termination of third median nervule, this 
portion also being slightly excavated, from third median ner-vule to inner angle strongly 
inwardly oblique, also slightly concave ; inner angle rather acute ; inner margin siniious ; 
costal nervure very short, not nearly reaching opposite to the apex of the discoidal cell ; 
first, second, and third subcostal nervules also very short, rapidly reaching the costa, fourth 
subcostal long, extending to apex of wing, the bases of all the subcostals nearly equi- 
distant ; terminal portion of subcostal nervure reaching outer margin below apex of wing ; 
discoidal cell long, narrow, reaching to more than half though less than two thirds the 
length of the wing ; upper discocellular nervule short, straight, outwardly oblique ; middle 
and lower discocellulars straight, slightly inwardly oblique, the lower a little longer than 
the middle ; second median nervule arising considerably before the lower end of the cell ; 
first median arising much nearer to the base of the wing than to the lower end of the cell ; 
submedian nervure sinuous, following the outline of the inner margin ; internal nervure 
short, running to the submedian nervure as usual. Hind wing with the base of the costa 
much produced, thence gently curviug to apex ; outer margin slightly produced, tooth-like 
at apex of first subcostal nervule, very strongly at third median nervule, thence inwardly
