tj. Distal margin of forewing straight. Discal line of hindwing below curved, 

 about 2 mm. distant from cell at W. 



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

 does not seem to be a constant diiference 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.

Bntler, I.e., mentions a " d " as marginalis ; as there is no S in the British 

 Museum, he meant perhaps another species.
