REVISION OF AFRICAN SPECIES OF CLEORA 79 



white, irrorate with drab and fuscous and, distad of postmedial fasciae, with pale smoke grey ; 

 transverse fasciae fuscous ; some warm buff irroration proximad of antemedial fascia on fore 

 wing and distad of postmedial fascia on each wing, well-defined on fore wing between veins Mi 

 and A/3 ; cubital veins and other veins distad of postmedial fasciae interruptedly warm buff ; 

 a lateral fuscous streak between veins A/ 2 and M 3 on fore wing, extending from postmedial 

 fascia to termen (PI. 10, fig. 313). Underside white patterned with fuscous (PI. 10, fig. 314). 



o*. Genitalia (Text-figs. 103, 104). Tip of uncus tapered and depressed ; scobinate medial 

 plate of gnathus slender and tapered ; apex of juxta broadly Y-shaped and rugose ; apical 

 process on sacculus short and digitate ; two minute, setose digitate processes arise at mid-valve ; 

 a further similar, but slightly larger process is situate midway between first pair and ventral 

 margin of valve ; apex of aedcagus incised ; vesica with two stout, tapered cornuti fused at base, 

 one one-half and one three-eighths as long as aedeagus. 



$. Pattern similar to that of male, but drab and fuscous irroration of ground colour greatly 

 reduced ; the slender and sharply marked transverse fasciae and the pale smoke grey irroration 

 distad of the postmedial fascia on each wing and the warm buff irroration and fuscous lateral 

 streak in the discal area of the fore wing distad of the postmedial fascia are conspicuous (PI. 10, 

 fi gs- 3*5- 3i6). 



$. Genitalia (Text-fig. 102). Lamella postvaginalis strongly sclerotized medially ; posterior 

 margin of colliculum sharply defined ; anterior sixth of bursa copulatrix dilate and membranous, 

 remainder cylindrical, ribbed and sclerotized. 



Measurements, o* 36-42 mm. ; $ 44-49 mm. 



In addition to the most common form described as the typical, this polymorphic 

 species displays a range of forms similar to those found in tidbaghata ; forms occur 

 in which the antemedial fascia on the fore wing and postmedial fascia on each wing 

 are broad and heavily marked (PI. 10, fig. 317) ; in another form the proximal 

 third of the fore wing and the distal third of each wing are densely fuscous (PI. 10, 

 figs. 318, 319) ; forms comparable with tidbaghata abs. flavipleta and fumata also 

 occur. 



In the typical form the pale smoke grey irroration distad of the postmedial fascia 

 on each wing, the warm buff irroration and the fuscous lateral streak in the discal 

 area distad of the postmedial fascia on the fore wing are distinctive. In the male 

 genitalia the depressed tip of the uncus, the rugose juxta, the structure of the sacculus 

 and the incised tip of the aedeagus and in the female the shape and development of 

 the sterigma are diagnostic.
