Imago. —Male. Upperside greyish-white. Foreiving with the veins basally 
slenderly black lined, the costal border and the outer veins more broadly black 
bordered, the upper veins slightly expanding obliquely before the apex and then 
outwardly dilating to the margin. Hindwing basally flushed with pale yellow ; with 
the end of the outer veins and marginal edge slenderly black bordered, the sub¬ 
marginal line of the band on the underside being also sometimes indicated. Under¬ 
side. Foreiving white, with all the veins more broadly black bordered; three 
longitudinal slender black lines within the cell. Hindwing chrome-yellow, the outer 
border white, the precostal interspace bright crimson ; veins black lined, the outer 
veins more or less submarginally expanded and then outwardly dilated, thus forming 
an ill-defined incomplete marginal band enclosing a series of white spots. 
Female. Upperside. Foreiving black, with greyish-white scaled longitudinal 
apically dilated cell-streaks, a cliscal series of streaks and short submarginal streaks, 
the lower of the two latter being sometimes slightly coalescent. Hindiving white, basally 
flushed with pale yellow; the outer veins broader black lined than in the male, the 
marginal black border also broader and preceded by a more or less defined blackish- 
scaled submarginal slender lunular band, thus enclosing a series of greyish-white 
spots. Underside. Forewing black, with markings as on the upperside. Hindiving 
similar to the male. 
Expanse, 3 to 3J inches. 
Habitat.— Sikkim; Bhotan ; Assam; Khasias ; Burma; Tenasserim ; Siam; 
Annam ; Tonkin. 
Distribution. —Mr. H. J. Elwes records it as “ occurring, but not commonly, in 
the lower valleys of Sikkim, from April to October, the female, however, seems quite 
rare ’ ’ (Tr. Ent. Soo. 1888, 411). Mr. L. de Niceville says it is “ quite rare in Sikkim, 
and occurs from April to October at low elevations. In many years’ collecting, Mr. 
Otto Moller obtained two females only ” (Sikk. Gaz. 1894, 166). Mr. G. C. Dudgeon 
obtained it in Bhotan. A male from Shillong, Assam, taken by Mr. J. P. Rawlins, 
is in the British Museum. Col. 0. Swinhoe records it as “very common in the 
Khasias ” (Tr. Ent. Soc. 1893, 310). In Burma it was obtained by Mr. O. 
Limborg at “ Houngduran and Naththoung to Paboga, Upper Tenasserim” 
(P. Z. S. 1878, 839). Dr, J. Anderson took it in “Mergui, and on Elphin- 
stone Island in March ” (J. Linn. Soc. Z. 1886, 50). “ Several males were 
taken in Tavoy, Ponsekai, and the Hills on the Siamese frontier ” (Elwes, J. As. Soc.
