 1870, p. 119, n. 4. 



Habitat : North-East India, Assam, Upper Tenasserim. 



Expanse: iJ, 2-3 to 3*2; ?, 3-0 to 34 inches. 



Description: "Male, Upperside as in C. rt/Ziawax, but the fascia a little broader, 

 white, and less well-defined inwardly on the hindwing. Foreiving with a single spot but 

 larger than in C. at/iamas. Underside as in C, atkamas, but the fascia broader." 



•' The fore wing is blunter at the apex than in 6. atkamas, Drury. We possess three 

 males in which the above character separating them from C. athatnas is very constant." 

 (^Feider, 1. c.) 



" I think that there can be little doubt of this being a variety of C. bharata ; Captain 

 Lang has several specimens agreeing pretty closely with Dr, Felder's description, but speci- 

 mens in the British Museum from Sylhet differ in having a second subapical spot in the 

 fore wing." (^BiUler, 1. c.) 



Dr. Feider in describing (7. bharata says nothing about the discal band being 

 of a different colour to C. atkamas, in describing C. aija, however, he says it is 

 white. I do not therefore agree with Mr. Butler in considering C, arja a variety of C 

 bharata ; in my opinion the latter is a variety of C. atkamas. As identified by me C. arja 

 has the discal band white, just tinted with palest green, it is very variable in width 

 as in C. atkamas, in one extreme it is double the width of the other extreme, and that in 

 the male sex only. The apical spots in the forewing are also variable, there being one, two 

 and occasionally three. The female has the discal band much broader than in the male. 

 I possess this species from Sikkim (where it is less common than C atkamas'), Sylhet, 

 Jorehat, Sibsagar, Chittagong, and Upper Tenasserim. From these localities it will be 

 seen that it is confined to the north-eastern portion of India and Burma. 



An apparently distinct form of this species occurs in Cachar (four males taken by Mr, 

 Wood-Mason), Shillong (two males taken by Dr. Johnson), Jorehat (one male taken by Mr. 

 J. L. Sherwill) and Sibsagar (one male taken by Mr. S- E. Peal). It differs from the common 

 form of C, arja in always having a single small subapical spot only in the forewing, the discal 

 band narrow ('25 of an inch in width at the inner margin of the forewing), the ground-colour 

 very deep indigo-blue on the upperside, and all the markings richer and darker on the 

 underside.

 tion is appended.* 



disc and at area of median nervules, and not prominently narrowing at posterior angle ; its inner margin 

 much waved. Hindwing with the dark subniarginal spots with white centres as in the variety of C. hebe here 

 figured, but prominently widened into a large blackish patch near apex. Underside as in C. hebe, but with 

 the medial pale fascis to both wings much broader, thus approaching the outer margins much more closely 

 than in Sutler's species ; the ground-colour is also considerably tinged with steely blue." 



" I have seen none but male specimens of this species. Its natural position is intermediate between 

 C. hebe, Butler, and C.jalysus, Feider." (Distant, 1. c.)

 Habitat: Perak, Province Wellesley, Malacca, Borneo. Exp.\nse : 2"7 to 3*3 inches. Description: 

 " Male. Upperside with the greenish-white area greatest. Fore-wing with a rather large .spot of this colour, 

 otherwise as in C. athamas. Underside with the area of the upperside but more restricted, somewhat 

 silvery, otherwise as in C nthatnas, but the lunules outwardly defining the fascia smaller, almost equal, 

 Forewing with the ferruginous cincture of the fascia extending to the upper di.scoidal nervule Hindwing 

 with the black submarginal spots much smaller. Female. Wings more denticulate, the area also broader." 



" In the form of the wings nearest to C. bha7-ata, Feider, but differing from all hitherto known allies of 

 C. attiamas, Drury, by the larger and narrower discoidal cell of the forewing. We received the species 

 together with a form of that common Javan species which is figured by Swainson as Jasia athama," 

 (Feider, \.Q.\ 



" Male. Upperside as in C. moori, but paler. Forewing with the black apical area considerably 

 smaller, its inner margin nearly straight. Hindwing with the submarginal border of spots more continuous 

 and amalgamated, but not dilated into a distinct patch at npex. Underside paler, and with the pale 

 medial fascia very broad and occupying the whole disc of both ivmgs ; on the hindwing this fascia is almost 

 straight outwardly, and not concave from costa to third medium nervule as in C. hebe and C. -inooti." 

 {Distant, 1, c. ) There is a single male specimen of this species from Perak in the Indian Museum, Calcutta.
