A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTER A) 121 



lustrous scales; anterior third of wing orange ; area between lines of antemedial fascia darker, 

 proximal line bordered proximally with highly lustrous white scales, distal line similarly bordered 

 distally. Arrangement of hyaline patches on fore wing as in holotype of prolixa (Plate 12, fig. 

 318) except that the patch between Cu la and Cw lb is twice as broad. Under surface of fore wing 

 buff (holotype), orange or yellow anterior and posterior to cell in basal two-thirds of wing, lightly 

 speckled with black ; cell and distal third of wing pink (holotype), orange, or reddish brown, or 

 very dark brown in those specimens with dark upper surface coloration. 



<J genitalia (Text-figs. 194-196) : valve with two basal processes, more distal process arcuate 

 apically ; aedeagus with two cornuti, vesica scobinate ; posterior margin of eighth sternum as in 

 figure. 



$. Unknown. 



Measurements. A.P.R. : $. n. Wing : <J. 115, 110-12-5 mm. ( IO )- 



Discussion. This species is externally similar to the closely related prolixa 

 except for the straight outer margin to the fore wing. The differently shaped valve 

 processes and the presence of two cornuti on the vesica distinguish the male genitalia 

 from those of prolixa. 



There is remarkable individual variation in the coloration in this species. Except 

 for an anterior orange or yellow area on that part of the hind wing probably normally 

 overlapped by the fore wing, the upper surface of both wings may be pale buff, pale 

 reddish brown, reddish brown, dark purplish brown or reddish brown, nearly black, 

 or buff heavily speckled with black (Plate 12, fig. 317). In one buff example the 

 area on each wing between the transverse fasciae is heavily speckled with black, 

 and the area distal to the postmedial fascia on the fore wing slightly less heavily 

 speckled. There is striking variation, too, in the size of the hyaline patch on the 

 fore wing which may be slightly larger than in the holotype (Plate 12, fig. 318) or 

 entirely absent (Plate 12, fig. 317). 



Distribution. Known only from east Madagascar. Apparently sympatric 

 with prolixa in this part of the island.
