A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTE RA ) 135 



(Text-figs. 219, 220). The shape of the dorsal region of the eighth abdominal segment in the 

 female genitalia is also diagnostic (Text-fig. 223). 



Measurements. Wing : q*- I 4'°. 120-18-0 mm. (34) ; $. 160, 140-19-0 mm. (7). 



Discussion. The high degree of colour variation has been mentioned in the 

 species description. Two females examined belong to the grey form (Plate 14, 

 fig. 326) (including the holotype of glaucinoe), two to the brown-spotted (Plate 14, 

 fig. 329) (one of the latter has pink fore wings), and the remainder (including the 

 holotype) to the yellow form of the species (Plate 14, fig. 328). Two of the males 

 belong to the brown-spotted form, five to the pink and yellow form (Plate 14, fig. 327), 

 three to a form similar to the latter but with the whole of the hind wing pink or 

 brownish pink, and the remainder to the yellow form. 



Distribution (Map 6). Known from the Ivory Coast, Ghana, Nigeria, 

 Cameroun and the Central African Republic.

Isospidia angustipennis torulus ssp. n. 



(Text-figs. 222, 224 ; PI. 14, fig. 329 ; Map 6) 



Diagnosis. $, $. Distinguished from the nominate subspecies by the genitalia. The lobe 

 at the base of the valve is smaller than in the nominate subspecies and two small digitate processes 

 are present at the posterior margin of the eighth abdominal sternum (Text-fig. 222) unlike the 

 nominate subspecies. In the female the shape of the dorsal plate of the eighth segment separates 

 the two subspecies (Text-fig. 224). 



Measurements. Wing : <$. 16-0, 15-5-16-5 mm. (5) ; $. i8-omm. (1). 



Discussion. The holotype, a male paratype, and the only female paratype 

 belong to the brown-spotted form of the species (Plate 14, fig. 329) ; the remaining 

 two male paratypes to the yellow form (Plate 14, fig. 328). 



Distribution (Map 6). Known only from Uganda.
