DESCRIPTION : ** MALE. UPPERSIDE, doth wings deep emerald-green, with a rich golden 
refulgence, spreading over the surface to a deep black border, which is narrow and regularly 
defined in the forewing, broader and indented in the hindwing. UNDERSIDE, ‘doth wings brown, 
in some individuals inclining to gray. Forewing with a series of three successively larger dark 
brown spots in the medial area surrounded with pearly shining rings, the first near the base being 
smallest, the exterior one on the disc constituting a short broad band bordered with white undulated 
marginal lines ; the contiguous portion of the anal area marked with two oblong tapering obliquely 
diverging spots of the same colour ; behind the disc follows a broad dark brown complete fascia, 
broken in the middle, with white undulated edges, and finally, parallel with the margin, a more 
obscure band with paler grayish undulations. Aiding with six or seven oval or irregularly 
round dark brown spots, narrowly edged with gray, disposed in two successive interrupted 
rows near the base ; next, a more prominent transverse band, of the same colour, simple and 
broad in the costal area, subdivided into two parallel branches, in the medial and anal area ; 
behind this an obsolete band parallel with the margin, faintly undulated with gray, and. 
succeeded in the anal region by three deep black oblong lunular spots, arranged in regular 
succession close to the margin, the interior one being somewhat larger and marked with an 
intensely black subocellate spot, the whole being confined along the inner edge by a waving 
emerald-green band richly covered with irrorations of a golden lustre. ody above agrees in 
colour with the adjoining portion of the wings, and below is covered with a light gray down. 
Antenne brown to the middle and ferruginous towards the extremity. The intermediate 
tail is slender, tipt with gray, and the lateral tails are very minute.”’ (H/orsfeld, |. c.) ‘SFEMALE, 
UPPERSIDE, 40th wings rufous-brown, with a lilac-blue spot from the base. Aindwing with one 
tail. UNDERSIDE, doth wings pale rufous-brown, with several spots before the middle, a spot 
at the end of thecell, a transverse band beyond the middle (broken on the forewing), all 
brown bordered with paler colour ; both with a submarginal brown band, zigzag on the 
hindwing. Hindwing with three black caudal spots, crowned with gold-green.” 
‘* This species and A. bazaloides, [Hewitson, habitat unknown], though closely allied to 
A, bazalus, Hewitson, are sufficiently well-marked as varieties, if not good species.” (//ewitson, 
l.c. of A. bupola.) 
Specimens of the female of this species from Sikkim “ differ from Hewitson’s figure of 
S. dupola in having an additional spot on the costa just beyond the spot closing the cell on the 
underside of the forewing.” (de Micéviile, 1. c.) With reference to this last remark of mine, I find 
on an examination of thirty-one examples in Mr. Otto M@ller’s collection, twenty-one inmy own 
collection, and some few others, that this spot is usually present, but it varies much in size, and in 
some examplesis entirely absent as in the specimen figured by Hewitson. I have found that this 
character is equally variable in the male. Hewitson, in describing the female, does not mention 
though he figures the patch of purple on thehindwing onthe upperside which is always more or 
less present in this species, Dr. Horsfield describes the female as follows, and says in one place 
that Cramer figured that sex, and in another the male:—“ FEMALE. UPPERSIDE, both wings 
black, the greenish-golden lustre being limited, in the forewing to a medial patch extending to 
the base, and in the Azzdwing to a triangular spot occupying the basal areolet.” Either in Java 
this species has a female coloured like the male, or Dr. Horsfield described males of two species 
as opposite sexes of one species ; the latter is much the more probable. I have no doubt whatever
