"I can quite imagine a tendency of planemoides to crop up 

 occasionally in the progeny of the S. African sub-species, 

 notwithstanding the remoteness of the equatorial model. 

 Indeed, something of this kind is noticeable in Cape Colony, 

 where the hippocoon form is occasionally met with as far as 

 /'. cenea extends, although its model Amauris dominicanus 

 is wholly absent." 



An East African variety of the female durdanus, described 

 and figured by Aurivilliufl as mixtus (Arch. f. Zool. l>d. 3, 

 No. 23 | !'- ,|j 7), T. l', f. 2), presents many points of resemblance 

 to leighi, but is intermediate between this form and the Hast 

 African planemoides described below. Mixtus differs from 

 leighi and approaches the example of pla in the 



iter development of the fulvous marking along the inner 

 margin of tin- fore-wing, in the greater length and size of 

 spot 5 (within tlic cell), ami in the whiteness and the much 

 greafo r of the hind-wing patch. Mixta* also apparently 



differs in the far paler tint of the fulvous markings. 



In such a protean w I do not think it is 



convenient to give separate names to all the single varieties 

 and transitional specimens, hut in leighi we have a form that 

 is not only distinguishable bu1 | I of sufficient stability 



to appear again and again over a very wide area. Furtherm 

 it i- the only planemoides-hkB form known in Natal.
