NYMPHALID^. NVMPHALIN^. CIRRHOCHROA. 117 



The above description is made from three males and four females from the Nilgiris, two 

 males and two females from North Canara, and one male and two females from Travancore. They 

 exhibit extremely little variation; the male differs from C. /(H/^j: in being larger, the ground" 

 colour of the upperside paler, the outer black border much less prominent, and the discal white 

 band on the underside being usually very wide and conspicuous. The female differs from that sex 

 of C. lanka in the ground-colour of the upperside also being paler, and the outer black border 

 less prominent. One male from the Nilgiris and the North Canara example differ from the 

 other typical specimens described above in being smaller, and the discal band of the underside 

 very obscure.

Habitat: South India. 

 Expanse : 28 to 3-0 inches. 



Description : " Male and female. Upperside, pale ferruginous, glossed with green 

 at the base. Forrwing with a prominent medial transverse black line, which is oblique and 

 zigzag in front of the cell and lunular hindward ; exterior margin broadly dusky black and 

 traversed by a double row of ferruginous lunules, the marginal row obsolete at the apex ; a 

 dusky streak lining the disco-cellular nervules. Hindwing with a large round white spot 

 on anterior margin, from which proceeds the medial transverse black lunular line, between 

 which and the exterior margin is a parallel row of six small black spots, two dusky lunular 

 lines and a third outer line. Underside pale ferruginous brown in male, brown in female, 

 with a transverse medial irregularly dentated purple-white glossy band on both wings, the outer 

 margin of the band being straight, and the dentations disappearing towards anal angle of hind- 

 wing ; transverse row of black spots on hindwing smaller than on upperside, marginal dusky 

 lunules hardly visible." 



" A^tV.— The above is the description of the insect which, according to Mr. Butler's deter- 

 mination, is the C. thais of Fabricius." {Moore, 1. c.) 



I possess one male of this species from Calicut, three males from Travancore, three males 

 and one female from North Canara, and one male and four females from the Nilgiris. They 

 show but little variation, and differ from the Ceylon form of C. thais (C. cognata) in being larger, 

 the outer margin of the forewing more emarginate, and the black markings on the outer border 

 far less prominent especially on the hindwing, in the colouration of the ground of the upperside 

 being usually paler, the discal white band on the underside nearly always prominent and highly 

 dentate in both sexes, in one Nilgiri male specimen only is it obscure ; in C. cognata it is never 

 nearly as prominent and usually quite obsolete. The female is also paler above and the black 

 margin less prominent, the forewing more deeply emarginate, the discal band below also more 

 distinct. Messrs. Butler and Moore (Cat. Fab. Lep. and Proc. Zool. Soc. Lond. 1872) give 

 C. thais from Ceylon, the description above applies best, however, to the South Indian form.

Habitat : Ceylon. 



Expanse : 2'0 to 3'o inches. 



Description : Male. " Upperside differs from C. thais in i\\Q /oieiviiig being shorter, 

 the apex broader and not falcated ; medial sinuous line indistinct, the marginal black band nar- 

 rower and traversed by a row of dentate spots, hindzving with a small white costal spot ; the 

 discal transverse markings similar, but the outer marginal line blacker. Underside dark fer- 

 ruginous, the medial transverse band narrower, less defined, and in some specimens nearly 



obsolete." 



" Larva pale purplish-brown, yellowish beneath ; head yellow, spotted in front with 

 black ; with two dorsal rows of long delicate branched spines and two lateral rows of shorter
