(J $ (PI- in, figs 1001, 1002). Hyaline area of wings often tinged with greyish yellow, 

 varyingly striate with grey and slenderly edged distally with yellow. Costa of fore wing yellow, 

 lightly irrorate with grey and suffused with orange or reddish orange at base. Non-hyaline 

 terminal area of wings orange (pi. 5, A7) to golden yellow (pi. 6, B7) varyingly irrorate with 

 reddish grey (pi. 10, B2) and dark grey and finely edged proximally and distally with dark grey; 

 subterminal fascia light yellow, dentate and usually very clearly defined; cilia chequered 

 yellow and grey. Underside of non-hyaline terminal area variable, brown to grey, darker 

 proximally; subterminal fascia buff and diffused. 



O* genitalia (Text-figs 271, 272). Ventral plate of gnathus triangular. Valves asymmetrical; 

 apex of left valve rounded and smooth, that of right valve truncate; dorsal process dilate 

 and setose in basal half. Fulcrum tapered and tipped with one or two stout spines. 



$ genitalia (PI. 58, figs 682, 683). Sterigma asymmetrical, as illustrated. 



Measurements. Fore wing: <$ iO'5-i4'5 mm; $ n-o-13-5 mm. Antennal pectinations: 

 $ 12 X, $ 4 X diameter of shaft. 



Externally a distinctive species; readily recognizable by the mainly orange- 

 coloured non-hyaline terminal area of the wings; each has a sharply marked, 

 yellow subterminal fascia and yellow and grey chequered cilia. In a few examples 

 the orange is densely suffused with shades of grey, but the subterminal fascia and 

 chequered cilia remain conspicuous. In the male genitalia the form of the dorsally 

 setose and asymmetrical valves and of the spine-tipped fulcrum and in the female 

 genitalia the form of the asymmetrical sterigma are diagnostic. 



Distribution. Kenya, Tanzania, Mozambique, Malawi, Rhodesia, Zambia, 

 Zaire.
