ExpPANSE: &, 9, ‘8 to 1°4 inches: 
DescripTION: “ MALE. UPPERSIDE, doth wings uniformly pale violet-blue, with a narrow 
grayish-brown posterior [outer] border, and two oblong black spots in the anal region, within 
[on either side of] the caudal appendage. UNDERSIDE, deth wings gray with a faint Isabella- 
yellow shade; marked on the disc with a short transverse stigma, which in the hindwing is 
slightly curved. Forewing has three ranges of catenulated bands of a brown colour, of 
which the two exterior are parallel with and adjoining the posterior margin, being confined by 
the marginal strige ; the third, in which the catenulated character is more distinctly exhibited, 
is intermediate between the marginal series and the disc ; this is continued through the hznd- 
weg, where it is more curved and somewhat irregular and infracted in its course ; in the 
marginal series of ocellate spots, the interior ones form two strongly-marked anal ocelli ; 
these are regularly round, nearly equal in size and brilliancy of tint, intensely black, 
encircled by a pale orange iris, bordered internally by a ring of yellow metallic irrorations, 
which is partially interrupted at the internal edge: the hindwing has further, four ocellate 
spots of an intense black colour with white iris, three of these are placed in a transverse 
series at the base, and a third, somewhat larger and more vivid, in the middle of the anterior 
margin close to the costa. Zorax above has a bluish cast and is covered with delicate hairs ; 
abdomen brown, underneath agrees in colour with the wings; ¢horvax underneath and 
Zegs covered with a delicate pure white down; anfezne banded with white. FEMALE. 
UPPERSIDE, both wings witha deep brown border ; a light blue tint with a bright silvery 
reflexion is, in the hindwing confined to the base, in the forewing expanded to the disc, but 
entirely evanescent in a certain position towards the light. Azzdwing, posterior border bearing 
a series of dark ocellate spots, of which two, at the anal angle, are of a deeper tint and sur- 
rounded internally with bright rufous crescents ; the penultimate ocellus exceeds the last in size 
and brilliancy of colour; all these ocelli are abruptly truncated behind, and the exterior 
ones are surrounded internally with narrow white crescents ; a row of angular or wedge-shaped 
marks of a brilliant white, having the points directed towards the disc, passes along the inner 
edge of the marginal series. UNDERSIDE, doth wings like the male. Cz/za throughout in 
both sexes gray.” (Horsfield, 1. c.) 
Larva when full-fed about half an inch in length, green, of the usual lyczenid shape, the 
head small, black, shining, retractile as usual. Colour of body pale green, with darker green 
or reddish dorsal and subdorsal lines, often with short oblique lines one on each segment 
on each side between the dorsal and subdorsal lines, the latter coalesced into a broad band 
between the eleventh and last segments. The entire surface of the body covered with 
minute white tubercles, there are also a few scattered white hairs, The segmental con- 
strictions shallow. Spiracles black. Extensile organs on the twelfth segment small. The larva 
is broader than high in its highest part, increasing in width to the fourth segment, from thence 
to the flattened anal segment of about uniform width. Bred by me in Calcutta on Phaseolus 
trilobus, Linnzus. Mr. W. C. Taylor reports that the larva feeds in Orissa on Dolzchos 
catjang, Roxburgh. Dr. A. Forel identifies the ant which attends the larva in Calcutta as 
Camponotus rubripes, Drury ( = sylvaticus, Fabricius), subspecies compressus, Fabricius. 
Pupa very pale green, the abdominal segments somewhat opaque, of the usual lyccenid 
shape, no distinctive structure or markings. Headcase somewhat square, thorax slightly 
humped, slightly constricted before the first abdominal segment, a dark dorsal line extend- 
ing the whole length, spiracles black, entire surface smooth, not hairy. Mrs. Wylly has furnished 
me with the following description of the preparatory stages of C. cwejus, ‘* Larva one half to 
three quarters of an inch long, onisciform, flattened at the tail and narrower; yellowish-green 
in colour, with brownish-red spots down the dorsal line. Some of the larve are darker 
red-brown, and some uniform pale green. The food-plant is an edible bean growing in the 
rains, with clusters of bluish flowers, vernacular names, Bargara (Uriah), Barbati (Bengali), the 
Dolichos catjang of Roxburgh. Larvze are attended by black ants of the larger species, in the 
same way as are the larvae of Zarucus theophrastus, Fabricius. Both species have the power of
