290 LYCANID. CURETIS. 
HasiraT : South Andaman and Nicobar Isles ; Cachar. 
EXPANSE: 6, 2, 1°4 inches. 
DESCRIPTION : ‘* MALE and FEMALE. Nearest allied to C. izsularis, Horsfield, of Java, 
but smaller, the forewing on the UPPERSIDE of the MALE having the black border less angulated 
on its inner margin; the UNDERSIDE of doth wings is white with slightly dusky undulated 
lines, C. insularis being cream-coloured, and with rather prominent undulated lines. FEMALE, 
UPPERSIDE, both wings dark brown, with golden-yellow disc.” (A/vore, 1. c.) 
I possess numerous specimens of both sexes of this species from the Andaman Isles, 
and one male and numerous females from the Nicobar Isles, where it occurs on Kamorta, 
Nankowri, Trinkut, and Great Nicobar, Females from the Andamans seem to be fairly constant, 
but from the Nicobars I possess some specimens with a large golden-yellow patch on the 
upperside of the forewing and a smaller one on the hindwing, and others in which the 
patch on. the forewing is reduced to a small ochreous suffusion on the disc, and on the 
hindwing the patch much smaller and whitish, and every intergrade between these two 
extremes. Numerous specimens taken by Mr. Wood-Mason in Cachar are indistinguishable 
from C. saronis in either sex. The solitary character which distinguishes the male of this 
species from C. arcuata, Moore, is the greater breadth of the outer black margin to the hind- 
wing on the upperside. The female of C. avcuata is said to be. white above, while that sex 
of C. saronisis ochreous. The colour of the underside distinguishes it from C. zzsularis.

HapitaT : Burma, Perak, Province Wellesley, Sungei Ujong, Singapore. 
EXPANSE: I'6 to I’9 inches. 
DESCRIPTION: “ MALE. Wings less angular than in C, @sofus, Fabricius, the apex of 
the forewing and the anal angle of the hindwing more rounded and less produced. UPPER- 
SIDE, doth wings coloured as in C. esopus. Forewing with the black area smaller, the apical 
portion more regularly concave interiorly, and narrower at the outer angle. Hindwing with the 
outer black margin narrower. UNDERSIDE, doth wings pearly-white, the markings as in 
C. @sopus, but the fasciee darker and more continuous, the apex of the forewing also broadly 
infuscated. FEMALE. UPPERSIDE, both wings pale orange-yellow. Forewing with the costal 
margin, the apex, outer margin, and outer half of inner margin broadly dark brown. Hind- 
wing wholly dark brown, with the exception of a large discal orange-yellow patch extending 
from the base of the third median nervule to the apex of the wing. UNDERSIDE, both wings 
as in the male, but with the fascize darker, broader, and more regularly curved and continuous. 
Body above dark brown; sternum and /egs ie -white, tibiz and tarsi annulated with 
brown ; falfi greyish-white, their apices dark brown.” 
“This! species is allied to C, izsu/aris, Horsfield (with the type of which in the Horsfield 
collection I have carefully compared it), but by the underside, in particular, it is rendered 
very distinct.” (Distant, 1.c.) This species is certainly distinct from C. insularis, but I 
am unable to find the smallest character by which to distinguish it from C. saronis, Moore, 
from the Andaman Isles. In the Indian Museum, Calcutta, is a male specimen from Perak, 
named by Mr. Distant, and another from Mergui captured on 21st March, 1882, by Dr. J. 
Anderson, and named by Mr. Moore, so I am sure of my identification of the species.
