REVISION OF GENUS ZAMARADA 223 



Externally distinct in colour and pattern; regularis in the flavicosta-group, 

 which it approaches in pattern, differs in its smaller size [wing-span 14-15 mm], 

 its yellow cilia strikingly chequered at apex and between veins M 3 and C« lb on 

 each wing and the appreciably longer antennal pectinations in both sexes. In 

 the male genitalia the form of the excavate uncus and in the female the form 

 of the lamellae are diagnostic. 



Distribution. Cameroun, Gabon. 



Material examined.

Zamarada aurolineata Gaede 

 (Text-figs 378, 379; PI. 78, figs 767, 768; PI. 116, fig. 1046) 



Zamarada aurolineata Gaede, 1915 : 120, pi. 2, fig. 15. Holotype <$, Cameroun (MNHU, 

 Berlin) [examined]. 



(J $ (PI. 116, fig. 1046). Hyaline area of wings tinged with yellowish green, striate with 

 brownish orange and finely edged distally with black; discal spots minute, black and sharply 

 marked; costa of fore wing striate with grey. Non-hyaline terminal area brownish orange 

 (pi. 6, C5-C6) overlaid in oblique light with purplish grey, boldly and deeply excavate between 

 veins M 3 and Cn lb ; dentate subterminal fascia light brown (pi. 6, D8), strongly marked and 

 finely edged distally with glossy buff. Underside of non-hyaline terminal area uniformly 

 greyish brown. 



Three examples from Fernando Po have the non-hyaline terminal area greyish orange 

 (pi. 5, B4) distad of the dark brown subterminal fascia and brownish orange (pi. 5, C4) proximad 

 of it. The underside of the non-hyaline terminal area is brownish orange darkening to greyish 

 brown near costa. Further material may shew these differences to be subspecific. 



o" genitalia (Text-figs 378, 379). Closely similar to those of clio, differing in the broader 

 uncus with its narrower and shallower medial excavation and in the form of the asymmetrical 

 ventral plate of the gnathus. 



$ genitalia (PI. 78, figs 767, 768). Distinguished from clio by the very slender, digitate 

 projection from the posterior margin of the lamella postvaginalis. 



Measurements. Fore wing: <J 18-21 mm; Cj 18 mm. Antennal pectinations: £ 9 X, 

 $ 4 X diameter of shaft. 



Similar in size and colour to dilata in the acrochra-group; distinguished in the 

 male by the markedly less dilate hind tibia and in both sexes by the sharply marked, 

 minute, black discal dots on the upper surface of the wings and by the uniformly
