the white coloration of the upperside,one extreme being entii-ely black, while the 
other has the costa and outer margin of the fore wing alone black, the black

" Body small, slender, and compressed. Wings generaUj* large, and of a delicate texture ; in 
the majority of the species blue on the upperside (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 disooidal 
cell of the fore wing. 
*' Head small, hairy, the hairs often forming a small tuft on the forehead. 
" Eyes 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. 
" Anteniice 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 disooidal coll, and with a third short branch about halfway between the cell and the 
tip of the wing ; discoidal cell closed by extremely slender middle and lower discoceUular 
nervules, which are transverse, the latter uniting with the third median nervule at a 
moderate distance beyond its origin ; upper discoceUular nervule very oblique, or almost 
longitudinal, forming, in fact, the base of the upper discoidal nervule. 
" Hind wiiKj [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, 
discoceUular nervules very concave, of about equal length, the upper discoceUular outwardly, 
and the inner discoceUular inwardly, oblique ; discoidal nervule from their point of jimction, 
discoidal cell very short, much less than half the length of the wing, second median nervule 
originating just before the end of the ceU." {de Niceville.)'] 
"Fore ler/s of the male slender, tibia in most species terminated by a short Curved horny point, 
in others simple ; tarsus slender, exarticulate, elongate, slightly curved and attenuated at 
the tip, which is terminated by a horny curved point, and armed beneath with short spines.
