98 Explanation of Plates. 



The specimens from ]\It. IMIanje, Nyasaland, are of great interest 

 as showing a local variety of the Planema with the pale areas on 

 fore- and hind-wings larger than in the typical S. African form; 

 this variety is faithfully copied by the local race of Fseudacraea 

 which shows a beautiful transition between the typical Southern 

 form imitator and the northern and most eastern of the forms of 

 euryius, namely rogersi, and also the Uganda and west-coast form 

 tirikensis. In the female the white subapical patch on the fore- 

 wing, larger than in typical imitator, is very like that in some of 

 the specimens of tirikensis most resembling their model {mamrista, 

 $), in which the posterior end of the white fore-wing bar is sup- 

 pressed (cf. fig. 7 and 8, jPlate II). On the hind-wing the Mlanje 

 females have a much larger white area than do the typical 

 Natal imitator, in this resembling the female rogersi. On the under 

 surface of the hind-wing the Mlanje specimens, both o and $, show 

 a basal red patch which in shape and tint is transitional between the 

 nanow but long piuplish red ])atcli of Natal imitalor and the more 

 triangular umber patch of tirikensis. 



The general apj)earance of these forms is sufficiently indicated by 

 the plates. I propose the name nyasae for the Mlanje race of 

 Planema aganice, and mlanjensis for the corresponding form of 

 Pseudacraea eari/tus.
