HasBitTaT: Shillong, Assam. 
EXPANSE: 4, 1°10 to 1'25; 2, 1°20 inches. 
DESCRIPTION: ‘*MALE. UPPERSIDE, doth wings lavender-blue. Forewing with the 
outer margin widely dusky-black, widest at the apex ; a dusky disco-cellular streak. ind- 
wing with the costal and outer margins widely dusky-black. UNDERSIDE, doth wings pale grey. 
Forewing with a slender disco-cellular streak outwardly defined with whitish, a discal slightly 
sinuous series of six small rounded spots also outwardly defined with whitish ; very pale and 
indistinct submarginal lunular line, marginal linear spots, and anteciliary line. Hindwing 
with two subbasal small black spots, a faint disco-cellular streak, and an irregular discal 
series of nine black spots outwardly defined with whitish, of which the third, fourth and 
fifth from the costa are much paler; marginal markings as on the forewing. Cv7/a of both 
wings somewhat dusky on the upperside, concolorous with the wings on the underside.” (de 
Nicéville, \.c.) FEMALE. UPPERSIDE, forwing dusky-black, with a small discal iridescent 
bluish-purple patch on the disc, a prominent disco-cellular black streak. AHindwing blackish, 
the lower discal area streaked with bluish-purple between the veins, and a submarginal series of 
oval black spots between the veins reaching the discoidal interspace ; the one in the submedian 
interspace geminate, each spot surrounded with a bluish line. Cz/ia of the forewing dusky, 
whitish on the hindwing, with an anteciliary black line. UNDERSIDE, 40th wings asin the 
male. 
From Shillong specimens of the female of C. jynteana, mihi, I can at once distinguish 
the same sex of C. chennellii by the blue discal pateh on the upperside of the forewing being 
much darker, in C. jynteana it is almost pure white in some lights ; and on the underside the 
discal spots of the forewing are arranged in a regularly sinuous line and are six in number ; 
in C. jynteana they are five only, and the anterior one is much out of line, being much nearer 
to the base of the wing, and all are placed angle to angle; moreover in C. 7yzteana the spots 
are elongated, while in C. chenmellii they are quite round. 
As far as I am aware, C. chennellii is confined to Shillong. It is a well-marked, easily 
distinguished species. It probably occurs throughout the warm months. I have specimens 
taken by Dr. E. R. Johnson and the Rev. Walter A. Hamilton in March, May and 
September.

Descriretion: ‘f MALE. UpPPERSIDE, doth wings somewhat dark lavender-blue. Forewing with the costal area 
and outer margin somewhat broadly fuscous, widest at base and apex. Hindwing, with the costal, posterior, 
and abdominal margins somewhat broadly fuscous. UNDERSIDE, doth wings greyish-white. Forewing with the 
costal area and outer margins slightly infuscated, and with the following pale fuscous spots :—a transverse 
linear one at the end of the cell, one between the third and fourth subcostal nervules, one above the upper discoidal 
nervule, three in linear series and nearer the outer margin, divided by the lower discoidal and third median 
nervules, and two larger, and placed more inwardly, divided by the first median nervule ; obscure, waved and 
broken submarginal and marginal pale fuscous fascia. Aiadwing with seven large and prominent black discal 
spots —one, small, between bases of costal and subcostal nervures, followed by two which are more rounded and 
much larger, one in the cell at about the base of the first median nervule, near which is a smaller spot, conti- 
guous, but outside the cell, and two situated on the abdominal margin ; these are followed bya discal series of 
six pale fuscous spots, the first and innermost of which is situated between the subcostal nervules near their base, 
second and third on each side of the discoidal nervule, aud fourth, fifth and sixth in irregular series, separated by 
the second and first median nervules; a transverse pale fuscous fascia at the end of the cell, and a much- 
waved pale fuscous submarginal fascia, between which and the outer margin are nine marginal spots, the 
upper four of which are pale fuscous, and the remaining five almost black. ody and /egs more or less con- 
colorous with the wings. FEMALE. UpPERSIDE, forewing fuscous, with a pale greyish-white discal space 
much suffused with bluish, extending from near the base through the middle of the cell above to about the 
median nervure beneath, and outwardly reaching the middle of the submedian nervules. Hindwing pale 
fuscous, with a similar but smailer pale discal area as on the forewing, and with the posterior margin fuscous 
asin the male. UNDERSIDE, doth wings as in the other sex.” 
**C. lambiis most nearly allied to the Ceylonese species C. ldavendularis, Moore.” (Distant, |, ¢. in 
Rhop. Malay.) I have seen two male specimens of this species from the Malay Peninsula.
