the black spots larger ; two additional spots to the discal series of 

 primaries, the lower half of the submarginal stripe of primaries 

 blackish, and that of the secondaries commencing with two short 

 black bars placed angle to angle ; a few black scales are also 

 sprinkled on the other divisions of this stripe.

An extraordmay specimen of what I take to be a very melanistic 

 form of this species, in which the spots on the primaries above are 

 greatly reduced in size and the white area of the secondaries is only 

 represented by an irregular central band : on the under surface 

 the markings are slightly thicker and blacker, but otherwise are 

 identical with those in South-African specimens. We are so badly 

 off for this species that it is possible that similar varieties of 

 the species may occur also in Natal. Until I compared the under- 

 surface pattern in the two insects, I imagined that they would 

 prove to be quite distinct.
