REVISION OF GENUS ZAMARADA 99 



^ § (PI. 104, figs 930, 933). Hyaline area of wings greyish yellow, slenderly edged distally 

 with dark brown; posterior margin of hind wing in male densely fringed with grey hair-scales. 

 Non-hyaline terminal area of each wing purplish grey proximad of reddish brown, dentate 

 subterminal fascia, which is slightly bowed proximad on fore wing between costa and vein 

 M 3 and edged conspicuously with white at tornus of fore wing and near anal angle of hind 

 wing; remainder of non-hyaline terminal area putty colour to light grey (PI. 104, fig. 930). 

 Underside of non-hyaline terminal area of wings dark brown; light buff spots at tornus of 

 fore wing and at anal angle of hind wing. 



Ab. tragodica Prout (PI. 104, fig. 933) differs from the typical form in having the non-hyaline 

 terminal area of each wing uniformly dark brown on both upper and under surfaces. 

 Described as a subspecies of melpotnene, it has subsequently been found occurring with the 

 typical form at Canzele in N. W. Angola, Kampala in Uganda and Kakamega in W. Kenya. 

 Both forms are identical in structure. 



In the male the mid and hind femora are fringed with long, buff hair-scales; the hind tibia 

 is dilate and densely tufted with similarly coloured hair-scales. 



$ genitalia (Text-figs 149, 150). Dorsal margin of valve very slenderly sclerotized and 

 scobinate apicad, apex produced slightly and tapered; dorsal process with setose projection 

 near base; hair-scales of coremata light buff. Aedeagus with a rounded apex and a tapered 

 projection at three-fourths. Fulcrum finely tapered at apex, lateral margins smooth. Vesica 

 without cornutus. 



$ genitalia (PI. 31, figs 575, 576). 



Distinguished externally in the male by its large size, by the uniformly light buff fringes 

 and hair-scale tufts on the legs and by the fringe of dark grey hair-scales along the hyaline 

 part of the posterior margin of the hind wing; distinguished in both sexes by the conspicuous 

 pale markings at the tornus of the fore wing and at the anal angle of the hind wing, on both 

 upper and under surfaces. In the male genitalia the form of the valve and in the female the 

 form of the sterigma are diagnostic.
