LYCANIDA. CURETIS. 291 
EXxPANSE: 1°6 inches, 
DEscrRIPTION: ‘‘ MALE. UPPERSIDE, Joh wings closely resembling those of C. ma/ayica, 
Felder, but the forewing having the black area much reduced, and not widened at the 
outer angle nor extending along the inner margin. UNDERSIDE, doth wings pearly-white. 
Forewing with a pale bluish oblique lunulated fascia, outwardly and narrowly margined 
with blackish, commencing at the upper discoidal nervule, and a marginal series of small 
black spots preceded by an obscure pale bluish lunulated fascia. Mindwing with a short 
oblique pale bluish fascia commencing on the costal nervure a little before the apex, some 
short and similar indistinct fascize on the disc, and a marginal series of black spots preceded 
by a pale bluish lunulated fasciaas on the forewing. Body above fuscous, beneath with 
the sternum and /egs greyish-white, femora and tibize more or less annulated with brownish ; 
abdomen pale brownish ; fa/fi greyish-white, with their apices black.” (Dzstant, 1. c.) 
Fabricius described this species froma female. Ido not give his description, as it will 
apply to any white female of this group. He gives the Papilio thetis of Drury, the type of which 
was also a female, as a synonym of C. @sopus ; in this he has been followed by Messrs. Kirby 
and Moore, but not by Messrs. Butler and Distant. As figured by the latter, the female of 
C. @sopus is absolutely similar in shape and markings to specimens of C, ¢hetds bred by me in 
Calcutta, the white patches of both wings are moderate in size, and the wings are evenly 
rounded. On the underside, however, the markings are more prominent and linear than is 
usual. Mr. Distant’s figure of the male of C. @sopus shows that the black border at the apex 
of the forewing is extremely wide, measuring ‘4 of an inch at its widest part, in this respect 
being only equalled by C. gloriosa, Moore, and C. fe/der7, Distant, and extending a short 
distance along the inner margin. Mr. Distant says that the black border does not extend along 
the inner margin, but in his figure and in a male specimen from Perak named C. @sofus by him 
and now in the Indian Museum, Calcutta, this character certainly exists, and thereby constitutes 
this species a distinct connecting link between the two groups, ¢/efis and duis, which in India 
proper I have considered to be possibly separable, 
C. insularis, Horsfield, occurring in the Malay Peninsula and Java, appears to me to 
be a distinct species from the small material I possess. Its description is appended.* 
In the second group of the genus, six species have been recorded from Indian limits. 
In this group we have two characters to deal with, a structural one and a colour one. With

14 to 17; female, 14 to 16 inches. DescripTion : ‘*‘ MALE. UPPERSIDE, doth wings with a bright cupreous 
lustre inclining as_ the light varies to’reddish-brown ; exterior and posterior borders of the forewing and poste- 
rior border of the hindwing black, in the former the intermediate boundary forms a bold curve leaving a 
broad apex, in the latter the inner edge is slightly waving and evanescent. Hindwing gradually attenuated 
towards the anai region, with a slightly rounded inner apical angle ; the concave inner margin wkich receives 
the abdomen is paler and covered with delicate hair of a sooty tint. UNprrRsSIDE, doth wizgs satin-white, 
the colour being spread in an opaque pulverulent stratum uniformly over the whole surface, and covered with 
a silvery slightly glaucous gloss. Both wings, have along their posterior margin a grayish line, behind the 
disc two very delicate waving strige of a blackish tint pass regularly across both pairs, the anterior being 
more pronounced ; just within the hinder margin is a series of very minute black dots, and near the middle 
of the inner margin stands a solitary dot of the same colour; on the disc the indication of a transverse brownish 
litura is faintly observed, which however is more lengthened and distinct in the hindwing. #ozy and 
abdomen above glaucous inclining to brown with a lengthened down of the same colour ; underneath yellowish« 
white and pulverulent ; Zegs of the same colour with obscure brown spots. Axtenne brown.” (Horsfiedd, |. Cc.) 
_“* Mate. Uprersipe, doth wings shining sanguineous. Forewing with the base brownish, the costal, 
apical, and outer marginal areas black. Hindwing with the outer margin black, the basal, abdominal, and 
anal-angular areas brownish. UnpersIDE, doth wings pale creamy-white with a stramineous tinge, crossed 
beyond the discoidal cells by a waved and more or Jess broken linear blackish fascia inwardly margined with 
bluish-grey, with a submarginal series of small black spots. Body above dark brownish, beneath more or less 
concolorous with the wings. FEMALE. UppERsIDE, doth wings dark chocolate-brown Forewing with a large 
discal orange-yellow patch which occupies the lower portion of the cell, is continued beneath the cell, and 
extends to a short distance from the outer margin. Aindwing with a small curved orange yellow patch e.tend- 
rie rae lpg subcostal nervule to about the end of the cell, UNDERSIDE, doth wings asin the male.’

There are two male specimens of this species from Perak inthe Indian Museum, Calcutta. On the 
upperside C. zmsularis is nearest to Perak specimens of C. @sofus, Fakricius, but the black border of the forewing 
on the upperside does not extend at all along the inner margin as it does in that species The underside is 
pale straw colour, which, together with the disca! straight linear fascia across both wings, distinguishes it from all 
other species known to me
