S. Distal margin of forewing straight. Uiscal line of liindwing below curved, 

 about 2 mm. distant from cell at W. 



?. Discal line of hindwiug as in S. We have seen four specimens ; there 

 does not seem to be a constant difference between these ? ? and the East African 

 ones, as the position of the discal line of the hindwing is variable in the Eastern 

 individuals (see above). A longer series of East and West African specimens must 

 be compared side by side in order to find out the difference, if there is one.

One of our c?(? is very pale, having lost nearly all the markings. 



Butler, I.e., mentions a " c? " as marginalis ; as there is no S in the British 

 Museum, he meant perhaps another species.
