REVISION OF AFRICAN SPECIES OF CLEORA 87 



cj. Genitalia (Text-figs. 115, 116). Uncus with minute thorn-like tip ; scobinate medial plate 

 of gnathus about two-thirds as wide as cucullus ; apex of juxta broadly Y-shaped ; sacculus 

 setose at apex, sometimes minutely produced ; a slender, setose, digitate process at mid-valve, 

 longer on left valve than right, and another shorter one, midway between first and ventral 

 margin ; vesica with two tapered cornuti fused at base, one three-fifths as long, and one one- 

 half as long as aedeagus, the shorter cornutus sparsely spined along one side. 



$. Differs from male in the vinaceous buff ground colour of the wings and in reduction of the 

 fuscous irroration ; a broad snuff brown fascia is situated proximad of the antemedial fascia on 

 the fore wing and a similar fascia is situated distad of the postmedial fascia on each wing 

 (PI. 11, fig. 343). Underside differs in the greyer ground colour of the wings and less well 

 defined pattern (PI. 11, fig. 344). 



9- Genitalia (Text-fig. 114). Lamella postvaginalis almost circular, weakly sclerotized except 

 medially ; anterior fourth of bursa copulatrix membranous, remainder cylindrical, ribbed and 

 very weakly sclerotized. 



Measurements. <J 32-37 mm. ; $ 35-41 mm. 



Externally variable in degree of development of transverse fascia. Variable also 

 in neuration ; in the fore wings of six of the 15 examples studied Sci and SC2 are 

 stalked ; in a further example they are coincident, and in two other examples SC2 

 anastomoses with the stalk of SC3-5. 



The genitalia of both sexes also show a degree of variation. In the male of the 

 type series the short digitate processes at mid-valve are asymmetrical in two 

 examples and absent in a third, they are absent also from a Vredendal specimen. 

 In the female from Ceres the medial sclerotized area of the lamella postvaginalis is 

 tapered posteriorly. 



Externally similar to some forms of quadrimaculata, but distinguished by the 

 lightly marked under surface of the wings. Structurally the male genitalia indicate 

 a close affinity with angustivalvis and serena, but are distinguished by the scobinate, 

 shorter cornutus on the vesica. In the female genitalia the weakly sclerotized 

 sterigma is diagnostic.
