And one unidentified species. 



A very heterogeneous collection of species have been described as 

 belonging to this genus, most of which belong to the genera Kerana, 

 Sancus, Koruthaialos, lumbrix, and Baracus. Of the remainder, 

 argenteo-ornatus, Hew., croites, Hew., and ojnone, Hew., belong to 

 Hesperilla or a closely allied genus ; dhamda, Moore, aurivittata, 

 Moore, and ladana, Butler, belong to Geltenorrhinus ; while ornatus, 

 Breni., and imicolor, Brem., belong to Heteropterus, 



Confined to Southern Asia. 



40. Genus Kerana. 



Kerana, Dist. Rhop. Mai. p. 402 (1886). Type, arma^MS, Druce. 



Anteuuse long ; club moderate, recurved at tip. Palpi : second 

 joint densely scaled ; third joint almost entirely concealed. Fore 

 wing : inner margin longer than outer ; cell less than two-thirds 

 the length of costa; vein 12 reaching costa before end of cell; 

 middle discocellular quite twice the length of lower one ; vein 5 from 

 close to bottom of cell ; vein 3 well before end of cell ; vein 2 almost 

 equidistant from vein 3 and base of wing. Hind wing : outer margin 

 evenly rounded ; vein 7 shortly before end of cell ; discocellulars 

 and vein 5 faint, but not fully developed ; vein 5 nearer to 4 than to 

 6 ; vein 3 well before end of cell, nearer to 4 than to 2 ; vein 2 

 nearer to end of cell than to base of wing. Hind tibiae clothed with 

 short recumbent scales and with two pairs of spurs. 



The male of the type species differs from the other species of the 

 genus in being provided with a patch of appressed scales occupying 

 the entire cell of the bind wing on the upperside, and giving it a 

 velvety appearance, and with a similar ill-defined patch towards the 

 base of the hind wing on the underside. A somewhat similar male 

 character is found in the genus Trichosemeia, Holland. The other 

 species of the genus are without secondary male characters.

The " Astictopterus " inornatus of Butler also apparently belongs 

 to this genus, but the type is in too bad condition to enable the point 

 to be decided. 



Confined to Southern Asia. 



41. Genus Katreus, nov. 



Type, johnstonii, Butler. 



Auteunse very long; club slender, recurved, apex acuminate. 



Palpi as in Kerana. Pore wing : inner margin longer than outer 



margin ; cell less than two-thirds the length of costa ; vein 12 reaching
