with the rest of the wings ; the veins throughout pale ochreous. Afiteinia black, the extreme 

 tip ochreous. Thorax and body rich ochreous above marked with three black lines, beneath 

 pale ochreous." (de Niccvilkt 1. c.) "Female differs from the male in being white below 

 instead of pale orange-ochreous ; above it is only slightly tinged with ferruginous, and is some- 

 what like C, thyodamas, except that the lighter spaces are heavily clouded with grey. When 

 flying it more resembles the white Indian species C. thyodamas, for which I at first mistook it." 

 (Doheity, 1. c.) The outline and markings are very similar to those of C. thyodamas, the 

 great difTerence being in the ground-colour. It is somewhat variable, the type specimen is very 

 much darker than the others subsequently received, in the former alone is the black irrora- 

 tion between the common discal lines of the upperside of both wings present. 



" Closely allied to C. thyonnens, Cramer (pi, ccxx, figs. E, F) from Amboyna and 

 Bouru in the Malay Archipelago, but differing from the above quoted figure in its much 

 darker colouration throughout on the upperside, more especially on the outer margins ; but 

 on the underside it is much paler." (de Nkcville, 1. c.) 



This beautiful species seems to be confined to the island of Great Nicobar, where the 

 late Mr. de Roepstorff and Mr. E. H. Man have each obtained two male specimens.

Habitat : Khasi Hills, Sylhet, Upper Tenasserim, Malacca, Perak, Siam, Andamans, 

 Orissa. 



Expanse : i -9 to 28 inches. 



Description : Male and female. Upperside, both wings with the ground-colour 

 pure white, very pale ochreous just tinted with apple-green at the base, or of a slightly darker 

 shade of ochreous ; the markings also variable in shade and intensity, in some specimens they 

 are hardly traceable, in others of a darker shade of ochreous than the ground, in others 

 again sepia. Both wings crossed at the middle by a band of the ground-colour devoid 

 of markings, outwardly bounded by a straight even narrow band, the inner edge irregular ; 

 the base crossed by numerous broad ochreous or sepia bands more or less defined with fine 

 black lines, the disco-cellular nervules enclosed by fine black lines, the outer portions of the 

 wings crossed by several irregular ochreous or sepia narrow bands, often obsolete at the 

 third median nervule of the forewing, and with a series of rounded and lunulated bluish 

 spots midway between the discal pale band and the margin, a prominent very fine black 

 marginal line. Hhidwing with the anal lobe and a spot above it at the anal angle irrorated 

 with black scales, and centred with a black spot, often outwardly marked with a rich ochreous 

 patch. Underside, both ivings much paler, many of the markings obliterated, two or 

 three small prominent black spots near the apex of \.h.e foreiving, and a large round one in 

 the first median interspace ; hiiidimng with a large round spot in the subcostal interspace, 

 followed by four fine linear ones between the nervules, the anal lobe with a large round 

 prominent black spot and a small one above at the anal angle, all but the two last mentioned 

 spots answering to the bluish spots on the upperside. Cilia pale throughout. 



C. cocks appears to usually present three distinct forms wherever it occurs, which, although 

 they differ in the colour of the ground and of the markings, also in the intensity and pro- 

 minence of the latter, agree in the style and position of the markings and in the shape of 

 the wings ; they also vary much in size. The typical form which has the ground-colour pale 

 ochreous with darker ochreous markings is here figured from a male Sylhet specimen in the 

 Indian Museum, Calcutta, and shows both sides ; exactly similar specimens occur in Orissa, 

 the Andamans and in Perak ; the form which FelJer described from the Andamans under
