Some of the specimens are labelled " wet " and some " dry," but 

 I see no appreciable difference between them. As before, the 

 whole are labelled with a varietal name, apparently because in the 

 Mashunaland and Swaziland examples the black spots on the 

 upper surface tend to become smaller than in examples from Natal. 

 I must confess I do not think the name is needed.

In this form (the seasonal phases of which do not seem to me 

 to differ) the two or three submarginal dots which usually occur 

 on the primaries of typical A. doubledayi are replaced by a con- 

 tinuation of the interuervular streaks ; the female also rarely shows 

 the subapical white bar of typical A. doubledayi ; it would there- 

 fore seem that A. axina is a smaller and localized form of A. double- 

 dayi, but intergrades between the two types occur in our Museum 

 series.

I see nothing to distinguish the " intermediate " from the wet 

 form ; our intermediate form from Nyasaland shows the fulvous 

 submarginal spots of typical (dry-season) A. anacreon. lam, how- 

 ever, grateful to Mr. Marshall for sending us examples of the wet 

 form in each collection, inasmuch as we did not possess it at all 

 until 1895. One of the males now sent has almost lost the 

 black spots on the primaries ; a similar but smaller female example 

 was obtained by Mr. Marshall on the 14th August, 1895, atGijima 

 (imZP.Z.S. 1898, p. 191).
