of both wings being quite half as wide, the underside brown not rufous, with an additional costal 
spot in the forewing. It differs from fig. 31 (1. c.) of 4. adatha on the underside in being brown 
not rufous, and in having the discal band in the forewing broken, less broad, and more macular. 
Mr. Hewitson gives Amboyna and Singapore as the habitat of 4. adatha, but as his figures in 
my opinion represent two distinct species, and he does not say which figure represents the 
Amboyna or which the Singapore specimen, I am unable, not having access to the types, 
to say which of these figures represents the true 4. adatha, (For further remarks on this 
species, see page 247). A. adorea is also closely allied to A. sz/hetenszs, Hewitson, from 
which the male differs in having the outer margin of the forewing very convex instead of 
straight, the hindwing posteriorly rounded, instead of much elongated as in A. si/hetensis ; the 
blue coloration of the upperside of the male also is richer and deeper, and the second spot of 
the discal series on the underside of the forewing no larger than the spot above and below it, 
while in A. sz/hetenszs it is produced outwardly far beyond the line of the others. 
Described from three males and one female from Singapore obtained by Mr. W. Davison. 
I have also seen a male from the Tenasserim Valley, Burma, collected by Mr. W. Doherty, 
and there are single males from Sikkim and the Khasi Hills in my collection. 
The figure shews both sides of the type male specimen from Singapore in the collection of 
the Raffles Museum, Singapore.

EXPANSE: 6, 9, 2°25 inches. 
DESCRIPTION: *‘ MALE. UPPERSIDE, doth wings lilac-blue, margins broadly dark brown. 
UNDERSIDE, doth wings brown. Forewing with a spot on the middle of the costa; a 
transverse band of six spots, the first four curving outwards, the fifth further from the outer 
margin, the sixth in a line with the fourth ; two spots in and one at the end of the cell, 
and a submarginal indistinct band. Andiwing with ten basal spots and a medial band of 
spots, of which the first two are distinct, the next four confluent, the seventh angulated, and 
the eighth on the inner margin elongated ; a submarginal indistinct band ; a black spot at the 
anal angle, above which and on each side of the tail is an irroration of silvery greenish-blue. 
FEMALE. UPPERSIDE, doth wings violet-blue.” 
‘“Near to A. atosia, [Hewitson, Il]. Diurn. Lep., p. 9, n. 37, pl. ii, figs. 8, 9, female, 
from Sumatra], but much larger, and the arrangement of the spots on the underside is quite 
different.” (Gvose Smith, 1. c.) 
I have not seen this species, which appears to be distinct. It is of large size, the sexes 
alike except that the male is lilac-blue, the female violet-blue on the upperside. There may be a 
mistake in the description, as both sexes appear to have an equally wide outer black margin 
on the upperside of both wings, which as far as I know occurs in no other species of this 
group. On the underside no mention is made of the two spots below the cell of the forewing 
which are divided by the first median nervule and are almost always present.
