Similar in colour and pattern to variola, which follows later in the genus in the 

 eucharis-gvoup. Distinguished externally by its shorter wing and by the smooth- 

 edged excavation of the non -hyaline terminal area between veins M 3 and Cu lh 

 and further in the male by the fringed hind femur and the dark grey, tufted and 

 grossly dilate hind tibia. 



In the male genitalia the form of the fulcrum and in the female genitalia the 

 form of the lamella antevaginalis are diagnostic. 



Distribution. Nigeria, Cameroun, Central African Republic, Zaire, Uganda.

Zamarada janata sp. n. 



(Text-fig. 420; PI. 86, figs 800, 801; PI. 122, figs 1089, 1090) 



cJ$ (PI. 122, figs 1089, 1090). Hyaline area of wings yellowish grey varyingly striate with 

 grey, the grey striae vinaceous tinged in oblique light, and finely edged distally with brown; 

 discal spot on fore wing brownish grey outlined with brown; discocellulars on hind wing very 

 slenderly brown. Non-hyaline terminal area narrow, brownish grey (pi. 5, C2), varyingly 

 irrorate with brown and whitish grey and smoothly and shallowly excavate between veins 

 M 3 and Cw lb ; weakly marked, dentate subterminal fascia present only in anterior and 

 posterior areas of each wing, because of the narrow width of the non-hyaline terminal area. 



The long tufts of hair-scales on the male hind leg are light buff at base, darkening apicad; 

 the grossly dilate hind tibia is buff varyingly irrorate with grey. 



(J genitalia (Text-fig. 420). Differ from those of latimargo in the shorter fulcrum, the serrate 

 apical fourth being dilate. 



$ genitalia (PI. 86, figs 800, 801). Differ from those of latimargo in the slightly asymmetrical 

 sclerotization of the lamella antevaginalis, the right side being better developed. 



Measurements. Fore wing: <$ 17-19 mm; $ 17-18 mm. Antennal pectinations: $ 6 X, 

 $ 4 X diameter of shaft. 



Externally distinct in the pale grey colour of the narrow, non-hyaline terminal 

 area.
