Habitat ; Andaman and Nicobar Isles. 



Expanse : $ , 2-85 to 3*6 ; ? , 2*8 to 4*0 inches. 



Description : " Male. Upperside pale brick red. Forezvmg with the cellular streaks, 

 the costa and the apical half blackish with large white spots and white dots. Uiudwittg W\\.h. 

 some more obsolete dots beyond the disc and the external border broad blackish, bearing near 

 its inner margin an obsolete series of brick red lunules, the lunulate marginal streaks obliterated 

 above, on the underside alike in both wings, very narrow, less distinct in the forewing." 

 {Fdder, 1. c. in Verh. zool.-bot. Gesells, Wien.) " Female : Blacker than the male. Forewino 

 with the lower basal portion and interspaces in cell dark greenish grey ; subapical marks broader, 

 the lower dentate mark formed into a streak. A^fWrww^ with the basal portion pale greenish 

 grey. Underside, greenish brown (in the male dull vermilion), interspaces of basal streak g 

 greenish (in the male bluish) ; black median transverse zigzag markings and discal dentate marks 

 and spots reddish white-bordered ; a black-and-white marginal sinuous band." {Moore, 1. c.) 



This species is a local race of C. dibits, but is sufficiently distinct. It occurs commonly 

 at Port Blair ; and has been recorded from Nankowri, Kondul and Great Nicobar in the 

 Nicobar group of islands. It differs from C. biblis in having the black margin of the hindwing 

 broader, the marginal series of white lunules obsolete, and on the underside the black markings 

 much more prominent, except those bordering the medial pale ochreous band which are obsolete 

 on the inner edge, and greatly reduced on the outer. The female is very differently coloured, 

 with a large white patch in the middle of the forewing. 



C, logani from Province Wellesley is another local race of C, biblis. A description of it 

 will be found below,*

" Head, broad, hairy. Eyes, oval, prominent, hairy. Palpi, porrect, ascending, rising above 

 the forehead, scaly ; the scales on the first joint long; the second joint hairy at the sides. 

 First joint short, transverse ; second four times the length of the first, subcylindric, slightly 

 swollen in the middle, tapering towards the base, and more so towards the apex ; third joint 

 about one-fifth the length of the second, slender, fusiform, the apex pointed. Antennce,

 I, pi. viii, iig 5, ?««/<; (1882). Habitat : Province Wellesley. Exfanse : 2'9 inches. Description: " ISIalb. 

 Upperside, yi)rt;7yz"«^ with the basal third bright red, remainder black with white markings; cell crossed by 

 three pairs of narrow black fasciae, the last pair somewhat indistinct, owing to the proximity of the black area ; 

 an indistinct arcuated spot beneath cell, and two somewhat waved linear spots separated by the first median 

 nervule ; the dark area contains the following white markings :— four spots a little beyond end of cell, of 

 which the tliird is very small ; beyond these are three large lanceolate spots, indistinctly margined with white, 

 divided by the discoidal nervules, and outwardly followed by a series of five small spots situated between the 

 nervules ; a very large and irregular subquadrate spot bounded by the third and first median nervules ; a smull 

 lunate spot beneath the first median nervule, and a submargiiial row of large but somewhat obscure 

 Innately linear spots. Hindiving bright red, with the outer margin broadly black, which is inwardly bordered 

 with a series of irregular spots of the same colour, and with nine or ten scattered and irregular black spots on 

 the basal area ; the broad black marginal border contains two small red spots divided by the discoidal nervule, 

 and a submarginal series of large pale, but obscure Innately linear spots. Undeksidb, foreiuinsr much paler, 

 the black apical area being brownish-ochraceous ; cell crossed as above, but the colour between the black fasciae 

 violaceous, all the white markings either larger or more distinct, the lanceolate spots beyond cell being wholly 

 greyish white, containing inwardly an ovate, linear black spot, and outwardly two rounded black spots ; the 

 marginal Innately linear spots paler and with central pale lines. Himiiuing paler and of the same hue as the 

 forewing, with a black subcostal line at base surrounded with greyish; an oblique greyish fascia near base 

 margined with black, each m.trgin with a double termin.rtiou at abdominal m.irgin ; a similar greyish fascia 

 crossing middle of wing, with much-broken black margins, the outer of .which is very pale ; a broad greyish 

 outer discal fascia containing a series of small black spots near its outer margin, which is black, and with a 

 similar but poorer and more irregular series near its inner margin, which is also more or less black ; ou'er 

 marginal lunate spots as on forewing, but more broadly margined with black. Body more or less reddish 

 ochraceous. Femalb almost indistinguishable from the male, but with the white markings of the forexving 

 a little larger." 



Nicobar 



" This species is most nearly allied to C nicobarica, Feider, which is found both in the Andaman and 

 obar Islands ; it is somewhat intermediate between that species and C. inetliypsea." {Distant, 1. c.)
