the white coloration of the uppcrside, one extreme being entirely black,vvhilethe 

 other has the costa and outer margin of the fore wing alone black, the black 

 spots of the underside showing through by transparency on both wings." 

 The species is also recorded from Cachar, Chittagong Hill Tracts, and 

 Shillong.

" Body small, slender, and compressed. Wings generally large, and of a delicate texture ; in 

 the majority of the species blue on the uppersido (at least in the males) and grey or greyish 

 white beneath, and more or less ocellated [as restricted by de Niceville all the species are 

 ocellated] ; the majority having a small black transverse spot at the extremity of the discoidal 

 cell of the fore wing. 



Head small, hairy, the hairs often forming a small tuft on the forehead. 

 " Etjes moderate sized, naked. 



" Palpi moderately elongated, compressed, scaly ; the middle joint also furnished beneath with 

 detached bristly hairs ; terminal joint shorter than half the length of the second joint, 

 and scarcely varying in length in the opposite sexes, slender, nearly naked, acute at 

 the tip. 



" Anteimce of moderate length, very slender, with long joints ringed with white, the club distinct, 

 suddenly formed, oblong-ovate, depressed, and sometimes spoon-shaped in dried specimens, 

 the joints of the club very short. 



" Fore wing generally elongate, subtriangularly ovate, with the costal margin moderately arched, 

 outer margin always more or less convex, inner margin rather short ; costal nervure short, 

 subcostal nervure wide apart from the costa, with two branches preceding the extremity of 

 the discoidal cell, and with a third short branch about halfway between the cell and the 

 tip of tlie wing ; discoidal cell closed by extremely slender middle and lower discocellular 

 nervules, which are transverse, the latter uniting with the third median nervule at a 

 moderate distance beyond its origin ; upper discocellular nervule very oblique, or almost 

 longitudinal, forming, in fact, the base of the upper discoidal nervule. 



" Hind wing [elongate-ovate, entire ; costal margin straight, apex rounded, outer margin very 

 convex, anal angle rounded, abdominal margin nearly straight ; costal nervure extending to 

 apex of wing, first subcostal nervule given off some distance before apex of discoidal cell, 

 discocellular nervules very concave, of about equal length, the upper discocellular outwardly, 

 and the inner discocellular inwardly, oblique ; discoidal nervule from their point of junction, 

 discoidal cell very short, much less than half the length of the wing, second median nervule 

 originating just before the end of the cell." (de Niceville.)'] 



*' Fore legs of the male slender, tibia in most species terminated by a short curved horny point, 

 in others simple ; tarsus slender, exarticulate, elongate, slight!}' curved and attenuated at 

 the tip, which is terminated by a horny curved point, and armed beneath with short spines.
