3. Upperside : both wings bright rather deep blue tinged with 
purplish, with a slight brownish lustre in one light ; costa and outer 
margin of primaries very finely black, almost linear; costa of 
secondaries broadly, outer margin very finely black; abdominal 
fold greyish ; tail fairly long, black tipped with white, lobe slightly 
developed, with small white spot on its interior and exterior margin. 
Underside: both wings olivaceous brown, with darker spots palely 
margined. Primaries a little paler than secondaries, with three in- 
creasing cell-spots, above and below the third being another spot ; 
transverse maculate band composed of six spots, the upper four 
slightly curved outwards and uninterrupted, the fifth shifted 
slightly inwards, sixth outwards and terminating on the lower 
median nervule ; below this in the pale submedian area is a trace of 
another small indefinite detached spot; submarginal row rather in- 
definite and indistinct, subdiscal area dark. Secondaries with four 
basal spots below each other, the third shifted outwards ; following 
these three larger ones below each other, the third one being again 
shifted outwards; cell closed by a large subquadrate spot, below 
which is a smaller triangular one connecting it with the lower of 
the three spots, whilst above it, touching its outer apex, are two spots 
over each other, the lower of which is the larger, having its outer 
margin shifted outwards, the upper one touches the costal nervure; 
the transverse maculate band commencing on the upper discoidal 
nervule consists of six spots—the first three almost confluent, but 
each curved very slightly beyond its predecessor, fourth shifted 
outwards, fifth angular spot right inwards and just detached, 
sixth long irregular spot almost confluent with it ; submarginal row 
fairly distinct, sublunular ; a black spot on the lobe and on the 
margin on each side of the tail; anal area covered with bright pale 
blue metallic scales, over which is a pale dusting up to the inner 
margin ; tail brown, tipped with white. 
2. Upperside: both wings slightly bluer than the male; pri- 
maries with broadish costa, broad outer margin, and broader apex 
of black ; cell closed with a very distinct black spot, and the apex of 
the blue area beyond the cell has three deep black spots in the 
nervule interspaces: secondaries with broad costa, less broad 
outer margin of black; abdominal fold greyish; tail black, tipped 
with white. Underside very much greyer than in the male, and 
in the secondaries the transverse maculate band just touches the 
outer lower margin of the two costal spots, and the fourth spot is 
shifted less outwards. 
This species is nearest to A. aroa, Hew., but that insect is much 
more purple on the upperside, and the arrangement of the three 
upper spots of the transverse band of the secondaries is different, 
and in the very large series of A. aroa now before me I find they 
follow the same pattern throughout. The female of A. kownga is 
quite different as to upperside and colour of underside, as already 
described.
