REVISION OF AFRICAN SPECIES OF CLEORA 89 



fascia of each wing sharply defined ; discal spots heavily ringed with bister ; a broad, ill-defined 

 band of pinkish buff to cinnamon brown proximad of antemedial fascia on fore wing and a 

 similar band distad of postmedial fascia on each wing ; cubital veins and other veins distad of 

 postmedial fasciae interruptedly light buff (PI. n, fig. 330). Underside of wings white, heavily 

 patterned with fuscous (PI. 11, fig. 331). 



<£. Genitalia (Text-figs. 118, 119). Uncus short and stout with a thorn-like tip ; scobinate 

 medial plate of gnathus of even width and rounded at tip ; apex of juxta broadly Y-shaped and 

 rugose ; sacculus strongly sclerotized, fused with and extending to three-fourths ventral margin 

 of valve then extending to a tapered tip, level with seven-eighths ventral margin ; a short, 

 setose, digitate process at mid-sacculus and two similar but minute processes nearer mid-valve; 

 aedeagus long and slender, one and one-half times as long as sacculus ; vesica with two stout 

 tapered cornuti fused at base, one one-half as long, the other slightly less than one-half as long as 

 aedeagus. 



$. Similar to male, but upperside of wings usually less densely irrorate (PI. 11, figs. 333, 334). 



$. Genitalia (Text-fig. 117). Sterigma asymmetrical and contorted ; posterior medial area 

 weakly sclerotized ; anterior fourth of bursa copulatrix membranous with two small projections ; 

 remainder of bursa ribbed and sclerotized. 



Measurements, o* 3°-4° mm. ; $ 39-50 mm. 



Variation in pattern similar to that of legrasi ; among a series of 160 specimens 

 are nine examples (PL 11, fig. 332) comparable with tulbaghata ab. fumata, one male 

 has the band distad of the postmedial fascia and the posterior half of the fore wing, 

 except terminal sixth, suffused with warm buff and one female combines the 

 characters of both forms. Distinguished externally from other known Madagascan 

 species of Chora by the clear white ground colour and sharply contrasted and heavily 

 marked pattern on the underside of the wings. In the male genitalia the develop- 

 ment of the sacculus and in the female genitalia the asymmetrical sterigma are 

 diagnostic. 



The strongly developed, rugose juxta, the development of the sacculus and the 

 long smooth cornuti indicate a close affinity with rostella ; the asymmetrical 

 sterigma, however, remains a unique curiosity in the genus.
