first slender and at the extreme base, the second broader and extending to posterior 

 margin, the other four still broader, the third terminating decreasinglj either at the 

 subraedian vein or posterior margin, the fourth, fifth, and sixth only crossing the 

 cell, the fifth being, more generally, wedge-shaped and not reaching lower edge of 

 the cell ; beyond is the much broader black marginal band decreasing posteriorly 

 and traversed medially by a linear I'ow oE narrow white lunules. Hindwing with a 

 black slender extreme abdominal marginal fold, outwardly fringed with grey hairs, 

 the fold beneath lined with long pale ochreous hairs ; a black transverse subbasal 

 band extending from the costa obliquely across base of the cell and thence more or 

 less decreasingly and less defined along lower median to above anal angle, followed 

 beyond by a parallel inner-discal more or less defined band, which is interrupted 

 across the cell, the anterior portion formed by a decreasing or constricted grey- 

 edged streak, the lower portion, from below apex of the cell to above anal angle, 

 being macular and grey-edged, and in some specimens the crimson streaks of the 

 underside are slightly apparent ; beyond is a black marginal band with incurved 

 sinuous inner-edge, traversed by a row of six slender white incurved lunules, the 

 caudal inner -interspaces of the band being speckled with grey scales ; cilia and 

 edges of the tail slenderly alternated with white. Underside. Forewing pale bluish- 

 white ; with transverse bands, as above, but of an ochreous-brown colour, the third 

 and marginal darkest. Hindwing with a broad subbasal transverse brown band, 

 a parallel inner-discal broken duplex-baud from the costa to anal angle, the inner 

 and outer portions, between the veins, being black (the inner sometimes dark 

 brown anteriorly), and each pair with a central deep crimson streak; the marginal 

 band, as above, pale brown, and traversed by six black outer lunules centred by a 

 slender white lunule ; cilia as above. Body black above ; thorax, front of head 

 and abdomen with a lateral greyish-white band ; abdomen beneath and legs greyish- 

 white, femora above black ; antennae black. 



Female. Upperside similar to the male. Hindwing with the discal crimson 

 streaks of the underside more apparent. Underside similar to the male. 



Expanse, c? 2|- to 3, ? 3 inches. 



Larva. — Unknown. 



Habitat. — Sikkim ; Bhotan ; Assam ; Khasias ; Burma ; Tenasserim ; Malay 

 Peninsula; Sumatra; Borneo. 



Distribution. — Mr. H. J. Elwes records it as " rare in the lowest valleys of 

 Sikkim, but found in abundance by Mr. Otto Moller's native collectors at Sivoke 

 in May" (Tr. Ent. Soc. 1888, 434). Mr. L. de Niceville says it "occurs in Sivoke 

 in April and May only, when it is very common. It is also found along the 

 Rungeet road in the same months, but elsewhere it seems scarce. It is single 

 brooded" (Sikkim Gazetteer, 1894, 174). Specimens from Shillong, Assam, are
