Holotype <$, Gabon: Mouila, 3.x. 1964 (P. Darge) in coll. Herbulot, Paris. 



Paratype. Gabon: Mouila, 10.ix.1964 (P. Darge), 1 <$ (coll. Herbulot, Paris). 



It is with pleasure that I name this species in honour of Monsieur Philippe Darge, 

 the distinguished collector of Cameroun and Gabon Lepidoptera. 



Zamarada hero Prout 

 (Text-figs 137, 138; PI. 31, figs 573, 574; PI. 103, fig. 923) 

 Zamarada hero Prout, 1921 : 154, pi. 18, fig. 23. Holotype <$, Zaire [examined]. 



$ 9 (PI- io 3< fig- 9 2 3)- Hyaline area of wings greyish green (pi. 29, B5), finely edged distally 

 with yellow, then dark brown; penetration of hyaline area into non-hyaline area varies, but 

 usually more extensive than in holotype (PI. 103, fig. 923); non-hyaline terminal area purplish 

 grey (pi. 14, D2) proximad of broken, dentate, brownish orange subterminal fascia; mainly 

 pale grey to light buff irrorate with purplish grey distad of it; tornus of fore wing and anal 

 angle of hind wing usually clear light buff to white. Underside of non-hyaline terminal area 

 dark brown, apex of fore wing and anal angle of hind wing buff. Anal tuft in male greyish 

 brown. 



Male hind femur fringed on inner surface with long, light buff hair-scales; hind tibia dilate 

 with a dense tuft of greyish brown and light buff hair-scales. 



$ genitalia (Text-figs 137, 138). Apex of valve smoothly rounded; dorsal margin narrowly 

 sclerotized; a short, scobinate projection just below level of apex; dorsal process with a short, 

 blunt, setose projection near base; hair-scales of coremata black. Aedeagus finely tapered; a 

 tapered projection at two-thirds, just subequal in length to greatest width of aedeagus; some- 

 times a minute, sclerotized ridge is present just apicad of tapered projection. Fulcrum simple 

 with rounded apex, similar to that of excavata. Vesica with a thorn-like cornutus. 



9 genitalia (PI. 31, figs 573, 574). Sterigma asymmetrical; posterior margin broadly rounded 

 at left side, bilobate at right side. 



Measurements. Fore wing: $ 13-0-14-5 mm; 9 13 mm. Antennal pectinations: £ 8 X, 

 $ 5 X diameter of shaft. 



Distinguished externally from sicula and dyscwpna by the deeper green of the 

 hyaline area of the wings and the well contrasted pale areas of the non-hyaline 

 terminal part; further distinguished in the male by the dense greyish brown hair- 

 tuft on the hind tibia and by the greyish brown anal tuft. Distinguished from 

 the closely similar radula and fusticula by the form of the valve and of the aedeagus 

 in the male genitalia and from radula by the form of the asymmetrical sterigma 

 in the female genitalia; the female of fusticula is not known. 



Distribution. Nigeria, Cameroun, Gabon, Zaire, N.W. Angola.
