14 ME. G. T. BETHUNE-BAKER: A REVISION OF THE 



an irregular indistinct whitish line, this is followed by a very broad paler band of the 

 ground-colour tapering towards the apex, edged outside by a fine, irregular, white line, 

 beyond which is a row of marginal spots, all of which are indistinct except those 

 adjacent to the tails, that by the first short tail being quite black, whilst the lobe-spot is 

 intense velvety black; these are edged above, and the space between them is filled in, 

 with a sparse scattering of submetallic green scales. 



2 ■ Upperside : both wings entirely warm darkish brown, with three tails, all white- 

 tipped. The costal area of the secondaries is pale. Beneath, the pattern in both wings 

 is like the male, but all the white markings are greatly accentuated and are brilliantly 

 pearly white, and the darker ground-colour is rich reddish brown. 



This species is nearest rochana Horsfield, but is very much larger, and the male has 

 three distinct tails, a unique feature in the whole group ; the metallic colour is 

 distinctly green in all lights, not blue ; and in the secondaries below the white marks 

 are distinct stripes and lines, and not broken up as in rochana. 



I figure a female from Celebes in my own Collection.

6 . Upperside : both wings blackish with a steely-blue lustre in certain lights, with 

 bright deep blue stripes in the cell, the median interspaces, and the submedian area ; 

 in the secondaries these stripes are confluent, forming a good-sized patch intersected 

 by the blackish nervures, the two tails short tipped with white ; lobe small, but well 

 defined ; antennas unusually long and tipped with whitish. Underside : both wings 

 pale ochreous with white spots. Primaries : cell closed by a white spot above and 

 below which are confluent, white marks extending to the costa and lower median 

 nervule, beyond which there is a patch of reddish, edged exteriorly by three white spots, 

 beyond which are three more smaller white spots in the apical area ; below the centre 

 of the red patch are two white spots, followed exteriorly by two larger black spots with 

 indefinite reddish margins ; submedian area dark grey, below which the ground-colour 

 becomes whitish. Secondaries with three white spots below each other encircled with 

 black rather near the base, beyond which are four more white spots encircled with 

 black, below the lowest of these and nearer the anal angle is an irregular black mark 

 pupilled with white extending to the internal nervure ; at the apex is a good-sized red 

 patch, at the outer edge of which are four small white spots encircled with black; a 

 marginal row of five white dots in the nervule interspaces and an isolated black spot
