ON NEW AND LITTLE-KNOWN BUTTERFLIES. 295 



interspace bearing marginally and outwardly some grey sprinklings ; 

 a prominent anteeiliary black thread, which is continued very narrowly 

 on to the forewing, but is there inconspicuous and pale fuscous, 

 inwardly defined in the hindwing by a pure white thread, anteriorly 

 becoming obsolete. Palpi whitish below, black above ; face with two 

 white lines ; thorax and abdomen above black, beneath pale leaden- 

 coloured. Antennas above black, beneath dotted with white, the club 

 beneath dull ferruginous towards the apex. 



This species is nearest to C. carmentalis, de Niceville,* from the Khasi 

 Hills, differing on the upperside in the more blue, less purple ground- 

 colour, which colour also is of greater extent in both wings. On 

 the underside C. carmentalis lacks the yellow base to the costa of the 

 forewing. It is remarkably similar on the upperside to Camena cippus, 

 Fabricius, which I possess from Assam, Bhutan, Kalar in the Ni]giri 

 Hills, and Karwar in North Kanara (the two latter localities are here 

 recorded for the first time), and Dr. L. Martin has it from North-East 

 Sumatra, caught by myself at Selesseh. It has been recorded from Nepal, 

 East Pegu, the Shan States, the Garo Hills, and Borneo, and doubtfully 

 from Simla and Ceylon. C. cretheus differs on the underside, however, 

 in not having a brilliantly-shining silvery ground-colour. It is also 

 near to " lolaus" ister, Hewitson, as figured, but that species does not 

 appear to possess secondary male sexual characters, and the orange 

 areas on the underside of the hindwing are much smaller. It is 

 not unlike the figuref of the male of u lolaus " isceus, Hewitson, 

 ( — « Tajuria" relata, Distant, teste Elwes in Proc. Zool. Soc. Lond., 

 1892, p. 637), but the discal line on the underside of both wings is much 

 nearer the outer margin in C. cretheus. It is probably nearest of all to 

 " Camena" icetoides, Elwes, $ from the Karen Hills, Burma, differing 

 therefrom apparently in having a large tuft of hairs attached to the 

 inner margin of the forewing, this tuft in C. icetoides being said 

 to be "absent or very much reduced ;" in the present species it is 

 large and whitish ; further, the orange costal streak to the forewing
