ever upon which to base such a decision, and therefore, in 

 spite of its affinity to the Angolan race of T. evippe, I am 

 constrained to consider it a distinct species. 



The argument on which Mr. Marshall bases his synonymy 

 of T. evippe and T. omphale, which he regards as one variable 

 species, is based upon the confusion which existed previous 

 to its rearrangement in the drawers of those species in the 

 Museum collection a confusion largely due to the incorpora- 

 tion of accessions since the date of the first arrangement of 

 the genus about the year 1876 or 1877. He says that in 

 Eastern Africa T. evippe is " an intermediate seasonal form 

 of theogone-omphale " ; but this is certainly not the case, for 

 T. evippe is essentially, in all its characters, a wet-season 

 phase ; nor does it appear to extend in the East further north 

 than Natal.
