proximad of it; subterminal fascia cinnamon-brown and sharply dentate, the points extending 

 along the irrorate veins to form streaks to termen; the fascia is edged distally between the 

 tooth-like markings with light buff to white; posterior margin of fore wing and large discal 

 spot on each wing cinnamon-brown. Underside: non-hyaline terminal area light buff to 

 light orange, fore wing suffused with light brown proximally, hind wing suffused with light 

 brown between costa and vein M 3 only; discal spots light brown. 



^ genitalia (Text-figs 179, 180). Similar to those of ferruginata, differing in the appreciably 

 broader valve and the shorter, bifurcate extension from the apex of the dorsal margin. 



$ genitalia (PI. 37, figs 599, 600). 



Measurements. Fore wing: £ 0- 15-16 mm. Antennal pectinations: £ 9 X , $ 4 x diameter 

 of shaft. 



The strongly marked, dentate subterminal fascia with its well contrasted, pale 

 distal border and the large discal spots readily distinguish arguta from ferruginata 

 and related species. Distinguished structurally by the male genitalia, as indicated; 

 the female of ferruginata is not yet known.

Zamarada dentigera Warren 

 (Text-figs 181-186; PL 38, figs 601, 602; PL 106, figs 949, 950) 

 Zamarada dentigera Warren, 1909 : 114. 



£ genitalia (Text-figs 181-186). Dorsal margin of valve slenderly sclerotized and smooth, 

 apex produced to fine point and inclined towards uncus; dorsal process with setose projection 

 at one-third; hair-scales of coremata light buff. Aedeagus tapered apicad; a short, bifurcate 

 projection at three-fourths. Fulcrum broad, bilobate at apex, below which is a pair of short, 

 rounded projections. Vesica without cornutus. 



9 genitalia (PI. 38, figs 601, 602). There does not appear to be any corresponding geographical 

 variation in the female genitalia. 



Measurements. Fore wing: $ 12-16 mm; i2*5-i5-omm. Antennal pectinations: g 9 x, 

 9 3 X diameter of shaft. 



The above $ description is based on the genitalia of the lectotype from Lagos, 

 matched by other Nigerian specimens (Text-fig. 183). 



Specimens from Ghana, Ivory Coast and Guinea differ in the form of the 

 projection from three-fourths aedeagus (Text-fig. 184). 



Text-figs 181, 182 represent the holotype of polymnia Oberthiir from Cameroun, 

 which is matched by examples from Angola, Kivu and W. Uganda; in the genitalia 

 of these examples the projection from three-fourths aedeagus is simple and the 

 fulcrum differs in being broadly rounded instead of bilobate at apex. 



In examples from E. Kenya, Tanzania and Malawi the projection from the 

 aedeagus approaches in form that of the lectotype of dentigera, but is distinct
