(S • Upperside : both wings purple, quite dull or somewhat 

 bright according to light ; costa and outer margin of primaries 

 narrowly brown ; costa of secondaries broadly, outer margin nar- 

 rowly, brown ; tail long, tipped with wbite, lobe fairly distinct, 

 abdominal margin grey. Underside : both wings ochreous brown, 

 with darker spots palely margined, those before the transverse 

 lines being the darkest. Primaries with three good-sined increasing 

 cell-spots, above and below the third is another spot ; subdiscoidal 

 area dark, with an indefinite pale luuular mark in the upper part 

 at the centre ; transverse catenulated band composed of six con- 

 fluent spots, below which is a double spot like the figure 8 ; the 

 upper four spots are sliglitly curved outwards, the fifth and sixth 

 have their inner margins shifted well inwards, but the outer 

 margins very slightly so, and these two spots have an outward 

 inclination ; submarginal row indefinite but fairly distinct ; sub- 

 median area paler. Secondaries with a small spot at the basal 

 upper extremity ; four basal spots below each other, second shifted 

 slightly inwards, fourth well inwards outside the internal nervure ; 

 beyond these are three larger spots below each other ; cell closed 

 by a long subquadrate spot, below which is a small spot in the 

 lower median angle ; transverse band beginning below the upper 

 discoidal nervule, composed of six laterally-edged spots, the second 

 shifted outwards, third inwards, fourth inclined outwards, fifth 

 angular spot right inwards; sixth long spot very irregular in shape, 

 slightly outwards, but extending up to the internal nervure ; just 

 above and between the uppermost spot of this series and that 

 closing the cell are two confluent spots occupying ,the interspaces 

 between tlie costal, subcostal, and upper discoidal nervures, the 

 lower of which is the longer of the two ; submarginal row inde- 

 finite but fairly distinct ; anal area occupied by bluish metallic 

 scales over a blackish patch ; tail brown, tipped with white ; lobe- 

 spot velvety black, edged above with metallic blue. 



2 . Upperside : both wings bluish purple, not nearly so deep as 

 in the male, with broad margins all round, the apical area being 

 the broadest. Underside : both wings rather darker than in the 

 male ; in the primaries the transverse band has no 8-shaped double 

 spot, but ceases on the lower median nervule. In the secondaries 

 the transverse band just touches the lower of the two spots on the 

 costa, and the three upper spots of the transversal series are 

 nearly (not absolutely) confluent, whilst the fifth and sixth are 

 confluent. 



In spite of these little differences, the two insects look so pre- 

 cisely similar in general pattern and tone that I do not doubt their 

 being sexes of the same species, which will come next to A. adatha, 

 Hew. There are a male and two females before me, all taken on 

 Kina Balu, and kindly lent to us by Dr. Staudinger.
