 OCYBADISTES, gen. nov. 



The three small Pamphilinee belong to an undescribed 

 genus nearest to Fadraona^ from which it differs in possessing 

 much broader wings and in having vein 3 of the fore wing 

 further from the end of the cell. The sexual mark on the 

 fore wings, where present, is a black slightly lunulated 

 streak crossing the disk from vein 1 to vein 4, instead of the 

 small streak over the centre of vein 1 of the fore wing which 

 some species of Padraona possess. 



The genus will include mamas, Felder, and Walkeri^ 

 sp. n., the latter of which will be the type. 



Lascivia, Rosenstock, has a small streak similar to that of 

 Padraona, though the shape of its wings and its neuration 

 would otherwise ally it to mamas, as stated by Watson 

 (P. Z. S. 1S93, p. 102). 



The genus may be thus characterized : — 



AntenncB about three fifths the lengtli of the costa of the 

 fore wings ; club of moderate size, elongate, with a slight 

 terminal crook rather longer than the thickness of the club. 



Palpi. Second joint thickly scaled, forming with the third 

 joint a quarter circle ; third joint about half the length of 

 the second joint, very slender, obtusely conical, and suberect. 



Fore wings. Breadth rather more than half the length of 

 the costa ; inner margin rather longer than outer margin ; 

 cell less than two thirds length of costa; vein 8 reaching 

 costa at apex of wings ; lower discocellulars two thirds length 

 of middle ; vein 5 considerably nearer to vein 4 than to 6 ; 

 vein 3 distant from 4 about the length of the middle disco- 

 cellular, and vein 2 a similar distance from vein 3 and very 

 slightly nearer end of cell than base of wing. 



Hind wings. Outer margin even, slightly excised between 

 veins 2 and 1 h ; vein 7 well before end of the cell (except in 

 mamas, $ , where it is emitted just before the end) • disco- 

 cellulars very inconspicuous ; vein 5 wanting ; vein 3 close 

 to end of cell, twice as far from 2 as from 4 ; vein 2 much 

 nearer the end of cell than base of wings. 



On the upperside of the costa of the hind wings of both 

 sexes are stout backwardly-directed hairs arranged in a short 

 row, and in addition fine long hairs projecting outwards and 

 forwards, which, inconspicuous in the females, are largely 

 developed in the males. 



The males are usually provided with a discal sexual streak 

 on the upperside of the fore wing, consisting of the more or 

 less lunular silky marks between vein 1 and vein 4, which
