terminal half of the wings in the <5 ; the discal transverse band 

 in both sexes is slightly broader, in the $ sometimes margined 

 outwardly with a very broad diffuse dusky-black shading in the 

 interspaces. 



Exp. S 2 62-75 mm. (2-48-2-98"). 



Hah. Southern India, Ceylon. 



After carefully examining long series of specimens from Southern 

 India and Ceylon, I am quite unable to find any constant characters 

 that would serve to distinguish C. lanlca, Moore, from C. thais, Eabr.

3 $ . Closely allied to C. aoris, but in both sexes the apex of 

 the fore wing is rounded, not truncate, the termen straighter, 

 more erect, the wing not apically produced. — $ . Upper side rich 

 fulvous tawny, the basal area limited by the transverse discal 

 black line, darker on both fore and hind wings than the discal 

 and terminal portions of the wings. The black markings are 

 similar to those in C. aoris, but differ as follows : — Fore wing : 

 veins not black, concolorous with the ground-colour of the wing ; 

 discal transverse black line not so sinuous ; subterminal black 

 zigzag line heavily marked, complete from apex to vein 1, black at 

 apex more diffuse ; the terminal edging of black slightly more even 

 in width. Hind wing : black markings absolutely identical with 

 those on hind w T ing of O. aoris. Underside : ground-colour 

 a darker, more uniform ochraceous than in C. aoris, slightly 

 suffused with purple ; the markings similar, but the transverse 

 discal band of a much more even width on the fore wing ; there 

 is a distinct shade on the middle of the terminal half of both fore 

 and hind wings, darker than the rest of the ground-colour ; the 

 subterminal markings are slightly more distinct, and the fore wing 

 is without the white apical patch so conspicuous in C. aoris. 

 Antennse, head, thorax and abdomen as in C. aoris. 



2 . Resembles the dry-season form of the $ C. aoris, but in 

 addition to the difference in the shape of the fore wing mentioned 

 above, the ground-colour and markings differ as follows : — Upper- 

 side : ground-colour a richer, brighter yellow. Tore wing : the 

 black line defining the inner and outer margins of the broad 

 bright yellow transverse discal band much less sinuous, less 

 sharply defined ; the subterminal lunular transverse line more 

 clearly separated from the black edging to the terminal margin. 

 Hind wing differs less, but the black line defining the inner margin 

 of the discal band is less sinuous and less curved, terminating on
