 4 $ Zamarada fessa paratypes) (BMNH); Khami, near Bulawayo, xi. 1956, 1 $

 Vumba Mts, Umtali, x-xi, 1^,1? (NMK, Nairobi), 1 <J (NMR, Bulawayo), 1 $

Zamarada eroessa Prout 

 (PI. 60, figs 692, 693; PL 112, fig. 1008) 



Zamarada eroessa Prout, 1915 : 344. Holotype $, Rhodesia (BMNH) [examined]. 

 Zamarada eroessa Prout; Janse, 1932 : 135, pi. 1, fig. 25. 



§ (PI. 112, fig. 1008). Hyaline area of wings lightly irrorate with grey; discal spots grey 

 mixed with black. Costa of fore wing brownish grey irrorate with black; an ill-defined spot 

 opposite discal spot. Basal area of fore wing and non-hyaline terminal area of each wing 

 pale grey, patterned as illustrated with black. Underside of non-hyaline terminal area greyish 

 brown, darker proximally. 



Measurements. Fore wing: $ 13-5 mm. Antennal pectinations: 0. 3 X diameter of shaft. 



The female holotype is similar in structure to fessa, with which it was taken 

 by F. W. Short at Selukwe in Rhodesia and of which it may prove to be an 

 aberration. As there exist two further species, undescribed because of inadequate 

 material, the original specific status of eroessa has been retained. 



The female illustrated by Janse under the name eroessa may prove to be a well 

 marked specimen of dorsiplaga. 



Distribution. Rhodesia.

Zamarada euterpina Oberthiir sp. rev. 

 (Text-figs 288, 289; PI. 61, figs 694, 695; PI. 112, fig. ion) 



Zamarada euterpina Oberthiir, 1912 : 258, 350, pi. 152, fig. 1458. Holotype <J, Zaire (BMNH) 

 [examined] . 



^ genitalia (Text-figs 288, 289). Acicular tip of ventral margin of valve extends to, or a 

 little beyond level of boldy rounded, dorsally setose apex of dorsal margin; a slender sclerotized 

 ridge is situate medially on ventral surface of apical fourth. 



§ genitalia (PI. 61, figs 694, 695). Differ from those of fessa in the smaller lateral lobes of 

 the sterigma.
