 light yellow to deep golden yellow, witli blackish, yellow-veined central 

 irregularly semicircular band, which is mostly interrupted between anal

 extent, in some specimens not larger than that above described in the

Found in all parts of inter-tropical Africa. The type-specimen 

 came from Algeria, but the species has uot been found there again 

 for more than seventy years. In the 9 from luhambane the basal 

 spot in hind wings is excej)tionally small and the yellow colour very 

 light.
