it approaches nearer T. evarne. T. vulnerata, Stand., is clearly the 

 dry-season form of the same species.

This is the northernmost African species in this group, being 

 recorded from Upper Egypt, Abyssinia, and Somaliland, southward 

 to Kilimanjaro. T. xanthevarne represents the fullest developmeiit 

 of the \^ et-season form, and approaches T.incretus ; typical T. evarne 

 is a little less strongly marked ; the specimens placed with T. syr- 

 tinus in the British Museum constitute an exactly intermediate 

 seasonal form ; and T. citreus is the full dry-season form. T.^hilipsii 

 is founded on dwarfed specimens from the Somali deserts, and, as is 

 always the case in such instances, it shows an unbroken gradation 

 into the typical form. 



Apart from other characters, T. evarne seems to differ constantly 

 from T. auxo and incretus in the more rounded shape of the fore 

 wings at all seasons of the year.

!r.^jseuc?efa«f/ie exhibits the strongly marked wet-season color- 

 ation ; T. aurora and titea are intermediates ; and T. eueharis and 

 pallens are the dry-season form, the latter showing a very close 

 relationship to T. evarne (Klug). This species frequents Central and 

 Southern India and Ceylon.

A curious species, linking the T. evarne and evij)pe groups ; 

 peculiar to Madagascar. T. ena does not seem to present any 

 characters entitUng it to specific rank.
