Aperusia gen. no v. 



Forewing : elongate : costa liiintly cnrved ; apex prominent ; hindmargin 

 obliquely cnrved, slightly indented above anal angle. 



Ilindwing : narrow; truncate at apex, indented befnre anal angle, the hind- 

 margin straight between veins 7 and 3. 



Antennae (c?) simj)le, lamellate ; paljii porrect, laxly scaled, resembling those 

 of Psaliodes ; tongue and frenulum present. 



Nenration : forewing, cell half as long as wing; discocellular vertically concave ; 

 median vein shortly intiected at end ; the second median nervule from the bend 

 shortly before the third, the first close before second, and curved downwards at 

 origin; vein 5 from rather below the middle of discocellular ; shortly stalked with 

 7, 8, 9 ; lu anastomosing with II, and again with 8, '.i, forming a double areole : 

 hindwing, costal and subcostal anastomosing for middle third of cell : 11, 7 from 

 upper angle, not stalked as usual ; discocellular deeply iiianguhite, and again angled 

 outwards just above lower end, vein Ti from this bend, and therefore close 

 above 4 ; 3 shortly before 4, 2 at two-thirds.

 and ipiite faint below it ; second line interrnptetlly double, from one-third of costa 

 to two-fifths of inner margin, angled dutwards in cell and on subniedian fold, 

 inwards on the veins ; outer line also double, from two-thirds of costa to two-thirds 

 of inner margin, angled outwards on veins 4 and ; both lines represented in parts 

 by brown dots, which also form irregular series in the space between them and in 

 those on either side ; a snbmarginal line of brown lunulate blotches between the 

 veins ; marginal spots iu pairs at the vein-ends ; fringe yellow ; cell-spot obscure,
