LYCANIDZ. ARHOPALA. 269 
DESCRIPTION: ‘Closely allied to but smaller than WM. [=4.] aroa, Hewitson, from 
Sumatra. FEMALE. UPPERSIDE, 0th wings dark violet-brown, costal edge and cz/ia paler, 
Forewing with the basal and discal areas violet-blue. Aindwing with the basal and medial 
discal areas violet-blue. UNDERSIDE, J0¢h wings of a similar tint of brown to that of 
aroa, markings also similarly disposed, but with darker centres. Forewing, cell-spots smaller 
and oval in shape, and the discal band broader. Hindwing, basal spots more rounded, 
the discal band more conspicious and less zigzag in shape, and the submarginal and 
marginal lunular line more distinctly formed ; at the anal angle is a black spot, and 
another between the median nervules, the spots and intervening space being speckled with 
metallic-green scales.” (JZoore, 1. c.) 
The type specimen of this species, together with four others, two of which Mr. Moore 
has himself named, are before me as I write. I cannot imagine how Mr. Moore could have 
written the last part of the above description, as in none of these specimens are there any 
black marginal spots on the underside of the hindwing, nor any trace, even under a very power- 
ful magnifying glass, of metallic green scales. 
Mr. Moore described the preceding species, A. zeta, from a female, and this species from a 
specimen of the same sex. Both occur in the Andamans, their size is nearly the same, no 
difference in the markings of the underside is traceable on comparing the description of 4. zela 
with the type specimen of A, voona, the only point of distinction between the two appearing to 
be that 4. zefa is (described as) “brilliant cobalt-blue ” on the upperside, while A. voona is 
“‘violet-blue.” It is so extremely difficult to hit off in words the multitudinous variations in tint 
of blue and purple occurring in the genus Arhofala that I doubt very much if this colour- 
difference is of specific value. It is very strange that Mr. Moore should have compared 4. voona 
with A. aroa, seeing that the latter has tails, is much larger, and the male is described as having 
a very narrow outer black margin on the upperside, It will be found described in a foot-note 
on page 244. Mr. Moore places ze¢a in the genus Safaadza, which is supposed to be tailed 
though his figure shews that it has no tail. Ihavea strong suspicion that A. zefa and A. 
yoona are one and the same species, but, as I have seen no authenticated specimen of the 
former, I keep them distinct for the present. 
A. roona appears to be rather a rare species. I have seen five specimens only, three of 
which have passed through Mr. Moore’s hands, and been named by him,

DESCRIPTION : ** MALE. UPPERSIDE, doth wings brilliant blue. Forewing with the apex, 
costa from near the base, and exterior margin broadly brown-black. Hindwing with the exte- 
rior margin broadly brown-black. UNDERSIDE, Joth wings pinkish-brown, slightly suffused with 
purple. orzwing with two spots in the cell and one beyond the cell, followed by a broad 
straight band of contiguous spots, the spots all being brown bordered with lighter pinkish- 
brown, a broad brown patch below and beyond the cell and exteriorly almost to the base, 
beneath which the space to the inner margin is pale brown. Hindwing with numerous brown 
spots bordered with light pinkish-brown. FEMALE, UPPERSIDE, o/h wings paler than in 
the male, and the margins less broadly black.” (Grose Smith, 1. c.) 
I am much indebted to Mr. Grose Smith fora pair of this species from the typical loca- 
lity. I also possess two males from Rangoon, and the Indian Museum, Calcutta, possesses two 
females from the same locality. Mr. R. Wimberley has sent me two males from the Anda- 
mans. The opposite sexes are almost exactly alike, but in the female the purple coloration on 
the upperside of the forewing does not extend into the upper discoidal interspace, while in the 
male it extends fully one-tenth of an inch along that space. The markings of the underside 
are very like those of 4. roona, Moore, but the discal band on the underside of the forewing
