middle one the longer ; vein 3 more than twice as far from 2 as 

 from 4 ; vein 2 considerably nearer to base of wing than to vein 3, 

 and about twice as far from end of cell as from base of wing. Hind 

 wing : outer margin sinuate ; middle discocellular very faint, almost 

 erect, lower well developed, outwardly oblique ; vein .5 wanting ; 

 vein 7 considerably nearer to 6 than to 8; vein 3 just before end of 

 cell ; vein 2 nearer to base of wing than to vein 3. Hind tibis" 

 slightly fringed and with two pairs of spurs. 



In tlie male there is on the fore wing a linear glandular streak 

 lying above the central portion of vein 1, and a second double streak 

 lying on both sides of the basal half of vein 2 : on the hiud wing 

 the basal half of veins 2 and 3 and the portion of the lower margin 

 of the cell lying between them are much swollen. On the under- 

 side of the fore wing also there is a patch of erect hairs extending 

 from vein I to the inner margin, and the hind wing above is thickly 

 clothed from its base with long hairs which conceal the swollen 

 veins. Abdomen conspicuously tufted above.

Antennae : club elongate, tip acuminate, recurved. Palpi: second 

 joint densely scaled, third joint almost concealed. Palpi and 

 antennae as in Kerana. Fore wing much elongated. " Male with 

 a curious impressed elongated oval brand placed so immediately 

 behind as to touch the median nervure." Vein 1 1 of the fore wing 

 strongly deflected upwards soon after its origin and touching the 

 costal nervure for a short distance ; vein 5 nearer to -J than to 6 ; 

 middle discocellular longer than lower one. 



Allied to Kerana, Astictopterus, lambrix, and Koruthaialos. 

 From the three former it may be distinguished by the confluence of 

 veins 11 and 12, and from the latter by the differently formed 

 palpi.

There has been some doubt about the correct synonymy of the 

 species of this geuus, chiefly owing to Heer Snellen having stated 

 that the characteristic " male mark " of the genus is wanting in 

 fuscula. The courtesy of the Hon. Walter Rotlischild has, how-
