the forewing and the hindwing, the former being considerably the darker. The markings of the 
underside are small and regular and not very prominent. The discal band on the underside of 
the forewing consists of five spots only, the three upper spots are in a straight line and placed 
outwardly obliquely, the fourth spot is shifted inwardly, the fifth is ina line with the third. The 
unique female mentioned above is only 1°3 inches in expanse ; the upperside is shining blue of 
the same shade in both wings, of the exact tint of the hindwing of the male ; there is no 
regular outer black border, but the blue colour gradually merges into the black.

DESCRIPTION : “ MALE. UPPERSIDE, Joth wings ultramarine-blue, the margins with a very 
narrow border of black. UNDERSIDE, doth wings rufous-brown. Forewing with the dand 
narrow, of equal breadth, formed of five spots, the middle spot projecting outwardly. Hindwing, 
crowded with unarranged spots, the anal angle with three black spots marked with bright 
blue. FEMALE. UPPERSIDE, doth wings like the male, except that the blue colour is lighter, 
the margins broadly brown. UNDERSIDE, forewing with the spots forming the transverse 
band differently arranged, che dast spot (as well as the middle one) Projecting outwards beyond 
the rest. regret that the figure does not represent this species as well as I would wish ; the 
transverse band of the forewing on the underside is too broad, and the spots which form it 
are not sufficiently rounded,” (Hezitson, 1. c. in Cat. Lycenide B. M.) 
‘I expressed my regret that the figure of this species in the British Museum Catalogue 
did not represent it to my satisfaction ; the band-of the forewing on the underside is there too 
broad, and does not represent as it ought the projecting medial spot. I have now repeated 
the underside without colour, and I trust that the arrangement of the spots will be distinctly 
seen This is one of the commonest species: it differs much in size, but may be known, 
on the upperside, by the very narrow border of the wings of the male and the very broad border 
of those of the female; on the underside by the transverse band of the male, which has 
the middle spot projecting outwardly beyond the rest, and by the same band of the female, which 
has the middle and last spot also projecting outwards.” (Hewitson, 1. c. in Ill. Diurn. Lep.) 
* Quite distinct from A. amphimuta, Felder.” (Butler, 1, c.) 
In speaking of A. aroa, Mr. Hewitson notes “A. Aypomuta seems, on the underside of 
the hindwing, as if covered throughout with spots, the spaces between the bands and spots 
having nearly the same appearance as the usual spots and bands themselves have.” (III. 
Diurn. Lep. p. 13, n. 60.) 
Much confusion appears to have arisen with regard to this species. Mr. Hewitson, in 
1862, placed the A. amphimuta of Felder, described two years previously, as a synonym of his 
species. At that time he had not seen Felder’s figure of amphimuta published in 1865 in the 
Reise Novara, or else he would not, I should think, have considered the two species to be one and 
the same. Messrs. Butler and Druce consider them to be distinct, as I do, judging from 
the figures and descriptions alone. Mr. Distant, however, following Hewitson, puts both 
species together, rightly giving precedence to Felder’s name. But to add confusion to confusion, 
he describes and figures as amphimuta a species with tails, while both Felder’s and Hewit- 
son’s figures show tailless species. I think therefore that Distant’s species is distinct from either 
of these, and I have named it Arhopala rafflesii. 
I have not seen 4. hyfomuta. On the upperside the male may be known from A. metamuta, 
Hewitson, by its ultramarine-blue colour on both wings, by its narrow thread-like marginal 
border, and probably also by the disposition of the spots of the discal band of the forewing 
on the underside,
