of the marginal markings of the forewing. Head, thorax, and Jody, deep blackish-brown above, 
yellowish underneath ; abdomen banded with yellow at the sides ; axfenne marked with delicate 
annuli. Za filiform, black, tipt with white. FEMALE with the wings broader and more 
expanded than in the male, and the abdomen more robust. UPPERSIDE, forewing with the 
transverse band approaching nearer to the costa than in the male, its posterior edge more 
deeply sinuated. Avxdwing has an interrupted row of obscure yellowish lineolz, parallel 
with the margin.”’ (Horsfield, 1. c.) 
The female of C.voxus may be known from that sex of C. ethion by having only one 
basal black band across both wings on the underside, while the latter has two such bands. 
Dr. Horsfield in 1829 recorded that “ Hitherto this species has only been found in Java: 
it occurs, in considerable numbers, in the skirts of large forests ; but from the great delicacy 
of the wings it is not easily obtained in a perfect state.” Further and later experience has 
shown that it has a wide distribution. But within our limits it is distinctly rare, the only 
specimens I possess being two taken inthe Thoungyeen forests, Upper Tenasserim, one in 
March, the other in the autumn, anda few from the Andaman Isles. Mr. Moore records it 
from Moulmein to Meetan: Colonel Lang, R.E., took one specimen in the Tenasserim Valley 
in March: and the collector of the Indian Museum, Calcutta, obtained it at Ponsekai on the 
borders of Siam. Mr. Distant records it from Sunjei Ujong and Malacca, and Mr. Butler 
from Singapore, all in the Malay Peninsula. It has been recorded also from several islands 
in the Malay Archipelago. Mr. Elwes records it* from Sikkim as “common up to 4 or 
5,000 feet from April to October,” He has wrongly identified the species, which does not 
occur in Sikkim at all.

DESCRIPTION : “FEMALE. Wings very shortly tailed, fuscous-brown on both sides, a 
common sinuate discal fascia and marginal spots white. UNDERSIDE with a white vitta at the 
base of the costa of the forzwing, and a common external white fascia, inwardly sinuate, out- 
wardly undulate.” 
**A female, much smaller than Z. [=C.] voxus, Godart, which appears to be the nearest 
allied species. The white spots on the margin arranged in rows on the upperside, and the 
absence of the short white band at the base of the costa on the underside of the hindwing are 
the only satisfactory distinguishing features of the new species.” (Felder, 1. c.) 
“MALE, UPPERSIDE, doth wings biack, with a broad white discal band, extending on 
the forewing from the hind margin to above the lower discoidal nervule, just entering the cell, 
at the end of which it is strongly indented from above ; prolonged outwardly between the 
second and third median nervules; on the hindwing it is broad, strongly produced out- 
wardly, acutely indented inwardly. Aindwing with a slender marginal white line, broken at 
the veins; tip of tail white. UNDERSIDE. Forewing, ground-colour white, base dark with a 
white longitudinal line close to the costa; a black mass extending obliquely from the base 
of the hind [inner] margin to the middle of the costa, where it joins a broad black subapical area 
which extends thence to the second median nervule, there it is connected (slightly) with the 
broad submarginal dark band, and with an outer discal dark area lying between the third 
median nervuleand the hind margin. Hindwing with a basal black mass untouched with white, 
and a discal band, irregular but unbroken, crossing the wing, and a submarginal line of wide, 
joined black lunules uniting at the apex with the discal band, Allied to C. roxus, Godart.”
