which is shifted well inwards, and is almost confluent with the long spot extending up 

 to the internal nervure ; submarginal band broad and distinct to the second median 

 nervule. Lobe-spot black, and a black spot between each of the two following nervure- 

 spaces, each broadly edged above with brilliant, very pale, greenish-blue, metallic 

 scales, over which is greyish irroration. 



Hewitson says : " Probably only variety of A. aclatha " (1. a). 



The species has no close affinity with adatha Hew. I have examined his type and 

 have a specimen also from the same locality (ex Mus. Dr. Staudinger) ; it is really more 

 like a miniature hercules, and will be best placed next to that insect. It has apparently 

 never been noticed by collectors since it was described, and the only specimens known 

 to me are in Hewitson's collection and one in Staudinger's collection, so that it seems 

 to be confined to the little island of Amboina.

3 . Upperside : primaries and secondaries deep blue, slightly lustrous, with very 

 narrow black costal and posterior margins to the primaries ; in the secondaries the 

 costal border is broad, the posterior margin narrow, the abdominal fold entirely dark 

 brown up to the submedian nerve ; the lobe is very slightly developed and is black. 

 Underside : both wings uniform brown, internal margin of primaries paler. Disco- 

 cellular spots three, dark brown, encircled with grey, increasing in size, the last one 

 closing the cell, below which and the central spot is another spot palely encircled. 

 The transverse band from the costa to the lower median nervule, increasing in width to 

 just below the second median nervule, is bordered on each side with grey ; touching 

 this band below the third median nervule is another spot placed nearer the base ; 

 submarginal band distinct but ill-defined, with a narrow posterior and a broad interior 

 lighter edge. Secondaries with four small basal darker spots palely encircled below 

 one another, the second placed a little inwards, and the fourth on the outside of the 

 internal nervure, outside these are three larger ones corresponding in position to the 

 three upper basal spots. The cell is closed by a long quadrate spot, below which 

 is another small spot filling up the interior end space between the second and lower 

 median nervule. Band continuous, but somewhat fractured at the upper discoidal 

 nervure and also at the lower median, whence it is continued upwards to the 

 internal nervure following the course of the margin. There is an indefinite trace 

 of a submarginal darker shading, between which and the median band is a pale grey
