Imago. — Male. Upperside dusky purpurescent-brown, somewhat palest exter- 

 nally ; cilia cinerescent brown. Forewing with a broad excurved discal brilliant 

 metallic- blue baud, which extends from the costal vein outside the cell to just beneath 

 the lower median veinlet, the blue being of a bright violaceous ultramarine tint, with 

 pale cobalt-blue scales disposed lunularly upon its outer half ; a slightly-defined 

 lilacine-speckled lunular streak descending from the costa before the apex. Hindmng 

 with a large medial-discal rounded similar brilliant blue patch, with pale cobalt-blue 

 centre. Underside paler ; the outer border broadly palest and somewhat cineresceut- 

 brown. Forewing crossed within the cell by two prominent darker purpurescent- 

 brown waved fascifp, one upon the discocellulars, an outwardly-oblique inner-discal 

 sinuous line, an erect outer-discal sinuous line, and a much less-defined zigzag sub- 

 marginal line ; the three latter lines outwardly-edged with lilacine-white scales, which 

 are sharply defined on the erect outer-discal line, the interspace between the latter and 

 the submarginal line being also sprinkled with lilacine scales. Hindwing crossed by a 

 similar prominent darker brown angulated subbasal line, a wavy inner-discal line, a 

 sinuous outer-discal line, and a less-defined zigzag submarginal line, the two latter lines 

 and their interspace speckled with lilacine scales ; between the subcostals is a pro- 

 minent small round yellow ocellus, with a black outwardly-disposed central dot and outer 

 black ring, and between the lower medians is a larger well-formed rounded ocellus, 

 with black centre speckled with a few lilacine scales, a slender yellow ring and a 

 black outer ring ; there is also a small black anal spot situated outside the end of the 

 submarginal line. Body, legs, and palpi dark-brown ; antennae reddish. 



Female. LTpperside as in the male. Underside also as in the male, but with the 

 markings more prominently defined. 



In the form named Bamcleo, the upperside of both sexes differs only in having 

 the brilliant blue patch extending over the whole of the middle of the wings, the 

 patch also being even more intensely brilliant in its lustre. The underside also differs 

 only in being somewhat paler, and in having the two ocelloid spots on the hindwing 

 smaller and less prominently developed. 



Expanse, <? 4, ? 4]^o to 4j% inches. 



Habitat.— Sikkim ; Assam ; Naga and Khasia Hills ; Silket ; Burma. 



DiSTREBUTiON. — " It is uot uucommou in Sikkim." Mr. Wood-Mason took it on 

 Nemotha, in Cachar, in September and October, noting that the " scent fans of the 

 male are vanilla-scented" (Butt. Ind. 305). " Fiamdeo is also found over the same 

 ground as Diores ; the Indian Museum, Calcutta, has it from Sibsagar, in Assam, and 

 from the Daffla Hills" {id. p. 306). According to Mr. Elwes (Tr. Ent. Soc. 1888, 

 333) " this species is not uncommon in shady ravines in Sikkim at from 2000 to 4000
