Boisduval’s description sufficiently shows the remarkable differences of form, size, and 
colouring which this species presents, compared with that of which he considers it a 
variety. The female agrees with the male, except that the colours are a little less bril- 
liant, and the cottony patches of the fore wings are absent. 
Expanse of wings, g, 5 inches; 9, 5-6 inches.

Remark.—This very fine species comes nearest to the last, but is of much larger 
size, and is conspicuous by its brilliantly coloured tails.

Hab. Java, Borneo, Sumatra (Wall.). 
The Bornean form differs from that of Java by its larger size, and on the under surface 
by the three middle lunules being formed of a violet line only, with scarcely a trace of 
red beneath it, and by the orange-red lunules both at the anal and outer angles being 
divided (not margined) by a violet line. The scales sprinkled at the base of the lower 
wings are white and blue, and are neither so dense nor do they extend so far as the 
yellowish scales of the Java specimens. In all these particulars the Sumatra specimens 
are somewhat intermediate, but approach most to those of Borneo. This is one of the 
examples Which show the isolation of Java, notwithstanding its proximity to Sumatra. 
f. Memnon group. 
(N.B. The Protenor group of India is intermediate between this and the last group.)
