 second antemedial, outwardly curved, banded with black on

 where it is nearly bifurcate, towards outer margin below the 

 middle, then down straight to the hinder marg'in about one 

 sixth from the angle, banded wnth black on the outer side, 

 fourth band marginal and is continued round the apex and 

 on the costa till it ends in the arm which nearly forms the

Resembles C. Platerd, Elwes, from N. Celebes, but that has 

 two discoidal spots on tlie fore wings and the subbasal band 

 of that species is of a different and very abnormal character.

 C'hioiimna subornata ($), Hmpsn. Phal. ii. p. 321 (1900). 



Ceylon ; type ? in B. M., Andaman Islands. 



The male (hitheito unknown) is very like C. obliquUineata, 

 Hmpsn., from Sikkim, the type of w hich is also in the B. M. ; 

 the lobe on the underside distorts the upper surface of the 

 fore wing and bends the ante- and postmedial bands, and 

 there are also some indications of the diffused fuscous patch 

 below the costa towards apex ; it is otherwise marked like 

 the female. I have received in a collection from Kandy one 

 male and two females, and 1 have both sexes from Port Blair, 

 Audamans, collected bv Wiraberlv.
