^ $ (PI. 116, fig. 1047). Hyaline area of wings weakly tinged with greyish yellow and 

 finely edged distally with black. Fore wing: costa deep buff, irrorate with iron-grey; discal 

 spot large, buff densely irrorate with brownish grey. Hind wing: discocellulars very slenderly 

 buff, occasionally with a grey dot at point of fold M 2 ; costa and subcostal vein brownish 

 grey. Non-hyaline terminal area of each wing brownish orange (pi. 6, C6); subterminal 

 fascia dentate and broken, brown (pi. 6, E6) ; proximad of subterminal fascia non-hyaline 

 area suffused with brownish grey (pi. 6, E2). 



In some examples the distal penetration of the hyaline area is shallow; in others the 

 non-hyaline terminal area is grey with a correspondingly darker grey, dentate subterminal 

 fascia. 



Underside of non-hyaline terminal area uniformly brown. 



$ genitalia (Text-figs 343, 344). Membranous part of valve acutely angled at point of 

 fusion with strongly sclerotized dorsal margin. Aedeagus tapered. Fulcrum extending 

 beyond tip of aedeagus. 



2 genitalia (PI. 77, figs 763, 764). See under species-group heading. Posterior fifth of 

 corpus bursae minutely scobinate. 



Measurements. Fore wing: <$ 17-21 mm; 2 16— 19 mm. Antennal pectinations: (J 8x, 

 2 2 x diameter of shaft. 



Externally similar to subincoloris Gaede in the principis-group, but with slightly 

 greater wing-span and a less yellow hyaline area; males of corroborata may be 

 separated readily by the presence of the grossly dilate, black hind tibia. The 

 genitalia of both sexes of corroborata and subincoloris are sufficiently distinctive 

 to be distinguished even in the dry state. 



Distribution. W. Africa, Guinea to Cameroun, Zaire.
