in length to diameter of eye. Thorax white. Hind tibia with outer spur of distal pair slightly 

 more than 1/2 length of inner spur. Proximal spurs long, inner proximal spur of hind tibia 

 longer than inner distal spur. Inner spur of distal pair equal in length to 1st hind tarsal seg- 

 ment. Fore wing, pattern as in PI. 19, fig. 97, white with pale yellow-brown markings. Black 

 spot at apex of cell and group of black spots between veins at apex. Veins yellowish. Hind 

 wing, pattern and colour as fore wing. Underside, paler with strongly iridescent costal fold, 

 costal margin darker (PL 19, fig. 98). Fringe of fore wing and hind wing yellowish. 



Genitalia £ (PI. 43, fig. 243). Saccus elongate. Anterior lobes of juxta with hairs, posterior 

 lobes sclerotized with many short spines. Basal process of valve lightly sclerotized, dorsal 

 part covered with spines. Gnathus weakly sclerotized. Aedeagus with lightly spined manica 

 and a group of short, stout, spines in vesica. 



9- Wing, 10-13-5 mm. Colour and pattern as male. Labial palps reaching slightly above 

 vertex. 



Genitalia <j> (PI. 65, figs 409, 410). Neck of duct lightly sclerotized. Whole length of duct 

 and bursa covered with minute plate-like spines. Tendency to have two distinct spine patches 

 and several smaller ones on bursa. 



Discussion. The intensity of pattern varies between specimens and there is 

 some variation in the male and female genitalia. In the female the amount of 

 sclerotization, producing small signa in the bursa, varies considerably between 

 specimens. The scattered nature of the signa in the female and, in the male, the 

 shape of the basal process of the valve, the spines in the vesica and the shape of 

 the juxta separate this species from the others in the genus. This species is dis- 

 tributed throughout west and central Africa and in Uganda.
