Gabon: Savanes de Mwadi, pres du Ieze, 26.iii.1963, 1 $; Belinga, Grande Crete 

 Sud, 900 m, 19.iii.1963, 1 <J (both G. Bernardi, in MBG, Paris); Wonga Wonghe, 

 12.ii.1967 (P. Darge), 1 <J (coll. Herbulot, Paris). 



Zamarada xyele sp. n. 



(Text-figs 374, 375; PL 118, fig. 1058) 



<J (PI. 118, fig. 1058). Hyaline area of wings almost colourless, with only a weak tinge of 

 yellow, posteriorly striate with pearl-grey and finely edged distally with dark brown; costa 

 of fore wing yellow striate with brownish grey; discal spots on both fore and hind wings large, 

 oval, pearl-grey edged with brown. Subterminal fascia dentate, yellowish brown (pi. 5, E8) 

 slenderly edged distally with glossy buff, strongly marked in subcostal, discal and tornal areas; 

 non-hyaline terminal area brownish grey (pi. 5, C2) proximad of subterminal fascia, brownish 

 grey mixed with buff distad of it; termen slenderly yellowish brown broken by buff-marked 

 veins ; cilia chequered buff and grey. Underside of discal spots and proximal half of non-hyaline 

 terminal area of each wing greyish brown; distal half of non-hyaline area of fore wing buff 

 partially suffused with greyish brown, that of hind wing buff; cilia as on upperside. 



$ genitalia (Text-figs 374, 375). Uncus almost square in shape with a short, ventrally 

 inclined projection from mid-apical margin. Ventral plate of gnathus very strongly sclerotized, 

 apex shallowly bilobate. Apices of valves incurved towards uncus, each tipped with a short 

 spine. Aedeagus with a minute, thorn-like projection at two-fifths. Apex of fulcrum 

 broadened, shallowly bifurcate and coarsely scobinate. 



0. unknown. 



Measurements. Fore wing: ^18 mm. Antennal pectinations: $ 9 x diameter of shaft. 



Distinguished in the principis-group by the large discal spot on the hind wing, 

 by the admixture of buff colour in the distal half of the upperside of the non-hyaline 

 terminal area of each wing and by the corresponding pale areas on the underside. 

 In the male genitalia the form of the uncus, valve and fulcrum is diagnostic. 



Distribution. Ivory Coast, Nigeria. 



Holotype <$, Ivory Coast: Korhogo [9°22' N. 5°3i' W.], viii. 1964 (P. Griveaud), 

 in MNHN, Paris. 



Paratype. Nigeria: Kaduna, 28.ix.1970 (H. Politzar), 1 <J (BMNH). 



The AUROLINEATA -Group 



Characterized in the male genitalia by the form of the asymmetrical valves 

 and of the aedeagus. Each valve is tapered apicad and curved towards the uncus; 

 left valve usually scobinate in part, apex acicular; right valve less finely tapered, 

 inner margin serrate in part; dorsal process dilate and setose near base, but 

 without digitate projection. Short, longitudinal, scobinate ridge usually present 

 along apical half of aedeagus. Fulcrum short and weakly sclerotized, extending 

 only to tip of aedeagus, usually dilate at apex and setose. Uncus stout, usually 

 shallowly bilobate. Ventral plate of gnathus well developed, minutely and densely
