Three ? ? : two from Barberton, S.E. Africa, and one from Fort .loUnstun,

Emmesxira gen. nov. 



Foreivinqx : with costa straight, convex before apex; apex blunt; hindmargin 

 obliquely curved. 



flimlwinqs : with anal angle si|nare, the hindmargin nearly straight. 



Abdomen of S with a lateral tuft of hair on each side in the middle: antennae of 

 S pectinated; palpi npcnrved in front of face, second joint with thick curled scales, 

 third short; hindtibiae with one pair of spurs; the legs all developed. 



JVeuration: forewings, cell not half as long as wing; discocellular thickened, 

 concave outwards: first median uervule at two-thirds, second exactly halfway between 

 first and third: lower radial from just above lower angle of cell, upper radial from 

 middle of discocellular; vein 7 bent downwards and forming the lower edge of a 

 thickened oval patch beyond the upper half of discocellular ; Costal vein bent down- 

 wards and anastomosing above discocellular with the subcostal, all the veins there 

 thickened; S, 9, in, 11, 12, rising nearly all together from beyond the cell, s into ajiex; 

 a thickened and snberect bed of scales from the discocellular to the costa between 

 veins 8 and 10. Hindwings normal: veins 0, 7, and 3, 4, from angles of cell; radial 

 from centre of discocellular.

Forewings : chalk-white, with very delicate and sjiarse rufous dusting ; the 

 lines very obscure, marked in the main by rufous dots on the veins at the edges of

 nearer base above the subcostal vein ; outer line at five-sixths, rufous, followed by 

 a rufous cloud, most distinct beyond cell and above inner margin ; a faint rufous 

 oblique median shade below the middle of wing beyond the reddish cell-spot ; a row 

 of rufous marginal spots between the veins ; fringe concolorous. 



lUndwings : the same. 



Underside whitish, with costal region of forewings towards base slightly dis-
