REVISION OF GENUS ZAMARADA 121 



dentate subterminal fascia dark brown slenderly edged proximally with reddish brown and 

 distally with silvery grey from costa to vein M t on each wing; posterior of vein Cu lb subterminal 

 fascia brownish orange; tcrmen of each wing greyish yellow (pi. 4, B6, amber- yellow) between 

 veins M, and Cw lb ; cilia chequered amber-yellow and purplish grey. Underside of non-hyaline 

 terminal area of wings dark brown anterior of vein M t , greyish orange suffused with dark 

 brown posterior of it. Tip of male abdomen dark grey. 



O* genitalia (Text-figs 197, 198). Dorsal margin of valve narrowly sclerotized; apex of 

 valve tapered and curved towards uncus. Aedeagus finely tapered. Fulcrum slightly 

 sinuous, without projections. Vesica with two cornuti, one hook-like and strongly sclerotized, 

 one weakly sclerotized and scobinate along one side. 



$ genitalia (PI. 41, figs 613, 614). Lamella antevaginalis an almost rectangular plate, but 

 with right posterior corner produced. Posterior margin of lamella postvaginalis irregularly 

 crenulate. Corpus bursae strongly sclerotized and minutely scobinate posteriorly. 



Measurements. Fore wing: <$ 12-13 mm; ? 13 mm. Antennal pectinations: J - 

 $ 3 X diameter of shaft. 



Distinguished externally by the presence of a --1< mlcr amber-yellow band along 

 the terminal area between veins M 3 and Cu lb on each wing. In the male genitalia 

 the form of the tapered valve and of the cornuti and in the female the form of 

 the sterigma are diagnostic. 



Distribution. Cameroun, Gabon.

Zamarada ariste sp. n. 



(Text-figs 199, 200; PL 41, figs 615, 616; PI. 107, fig. 957) 



O* 9 (PI- 107. fig- 957)- Closely similar in colour and pattern to aglae; distinguished by its 

 smaller size, by the presence of grey irroration in the hyaline area, especially its concentration 

 at the middle of the posterior margin of the fore wing, and by the larger discal spot on the fore 

 wing. The underside of the non-hyaline terminal area is more intensely greyish brown, 

 markedly so at the tornus of the fore wing and the anal angle of the hind wing in the Cameroun 

 specimens. 



3* genitalia (Text-figs 199, 200). Valve with weakly developed, longitudinal, medial ridge; 

 a tapered, digitate projection, two-thirds as long as uncus, extends posteriorly from mid- 

 apical margin. Aedeagus finely tapered to strongly sclerotized tip. Vesica scobinate medially 

 and having a short, sinuous cornutus with a thorn-like tip.
