Description: Male. Uppersidb, both ivings and cilia dark shining 

 hair-brown. Forewing with an oblique silvery lustrou s semi-trans- 

 parent discal band, which, commencing at the subcostal nervure, 

 crosses the discoidal cell towards the end and terminates in the sub- 

 median interspace opposite the and angle in the middle of the space ; 

 this band is rather narrow at its commencement, but rapidly widens 

 out till it reaches the median nervure, then gradually tapers to its 

 extremity, below which also in the submedian interspace is a most 

 minute dot ; an oblique slightly curved series of four subapical equaL 

 sized white dots, one in each interspace, with still a fifth most minute 

 one in continuation of the series in the lower discoidal interspace. 

 Eindwing outwardly a little paler than the rest of the wing, 

 obscurely streaked with darker colour across this paler area between 

 the veins. Underside, forewing as above, except that the discal 

 band is extended anteriorly up to the costal nervure, and the inner 

 area of the wing is a little paler than the rest. Sinchving concolorous 

 throughout. AntenncB dark brown, the club anteriorly pale. Palpi 

 above with the third joint dark brown, second and first joints 

 beneath chrome-yellow. Thorax, ahdomen, and legs dark brown. 

 Female. Upperside, /ore^^'m5r differs from the male in the discal 

 lustrous band being slightly wider, almost reaching the submedian 

 nervure posteriorly, and extending anteriorly almost to the costa in 

 an opaque creamy-white spot ; the five subapical dots twice as 

 large. Sindwing Math a discal series of five rather elongated spots 

 placed one in each interspace from the subcostal nervure to the first 

 median nervule. Underside, both ivings with the same differences 

 as on the upperside. 



I am indebted to the Eev. Walter A. Hamilton for the 

 gift of a single pair of this fine species in perfect condition, 

 obtained by his native collectors in the Khasi Hills ; he pos- 

 sesses five males and one female in his own collection, all of 

 which I have examined, and find that the species is a very 

 constant one. The figure of the male shews the dilatation 

 of the anal angle of the hind wing forcibly distent ed with the 

 setse spread out ; in nature the wing-membrane in this region 

 is folded under and backwards, and the setae lie across the wing 

 .beneath.
