convex : hind-margin entire or very slightly denticulate. 

 Hind-wings much rounded ; costa very prominent at base ; 

 hind-margin more or less dentate. Legs rather long, coxae 

 and femora and hind tibiae very hairy. Jbdomen not 

 reaching to anal angle of hind-wings. 



The seven South African species that I have included 

 under this Genus are all rather dull in colouring, and all 

 have transparent markings in the wings. The most cheerful- 

 looking is N, Mokeezi, in which the yellow hue of the 

 sub-vitreous bands relieves the brown of the general surface. 

 N. Kohela is very dark, and the largest of the seven species ; 

 the smallest being N. Djcslcelce.

Dark-brown, dusted loith yellowish and whitish scales ; a 

 few small vitreous spots. Fore-wing : a conspicuous darker 

 triangle, — its broad base on inner-margiuj its apex on costal 

 nervure, — a little before middle ; on the outer edge of this 

 marking are a sub-diaphanous spot close to costa, and a 

 vitreous litura (like a ? reversed) bordering it between jfirst 

 median nervule and sub-median nervure ; a smaller dark 

 triangle on costa rather beyond middle, its base on first 

 median nervule, outwardly edged by a line of three small 

 vitreous dots ; traces of a sub-marginal dark streak from 

 apex ; cilia greyish, interrupted with dark-brown. Hind- 

 viing : a vitreous or sub-diaphanous dot about extremity of 

 discoidal cell, sometimes obsolete traces of two darker fasciae 

 about middle ; cilia as in fore-wing. Under-side. — Dull- 

 ferruginous ; vitreous spots as above. Fore-wing : edges 

 pnly of dark triangles faintly indicated ; about extremity 

 of cell a brighter, almost orange space. Hind-wing : fasciae 

 more distinct, sometimes well-marked. 



On the hind-margin of fore-wing there is a shallow concavity between 

 third median nervule and sub-median nervure, and on that of hind-wing a 

 deeper one between discoidal and first median nervules. The hind-margin 

 pf both wings is generally more dentate than in others of the genus. 



Hillsides, settling on stony footpaths.
