than rest of wing. Hind wing, pattern and colour as fore wing. Sc+R x and Rs free, colour 

 and pattern as fore wing, position of dark spots variable. Underside paler than upper, sub-

Genitalia o* (PI- 44. fig. 252). Gnathus weakly sclerotized. Minute spines on manica of 

 aedeagus. 



$. Wing, 12-14 mm - Third segment of labial palp over 1/2 length of second. Colour and 

 pattern as male. 



Genitalia $ (PI. 66, figs 427, 428). The spines on the signum vary in length in different 

 specimens. 



Discussion. Very little variation of pattern is present although the number of 

 black subterminal spots on the fore wing varies between specimens. The single 

 Uganda specimen is slightly larger than the West African specimens but otherwise 

 is similar. This species has been bred from rice in Nigeria, where it was feeding on 

 the leaves.
