m] OLD-WORLD MIMICS 35 



Pseudacraea eurytus hobleyi (PL VII, figs. 6 and 7) shews 

 a similar difference in the sexes, the male and female of 

 this species mimicking respectively the male and female 

 of Planema macarista. The case is made even more 

 remarkable by the fact that both of the sexual forms 

 of Planema macarista are mimicked by the Satyrine 

 Elymnias phegea (PI. VII, fig. 9), though in this species 

 either the black and white, or the black, white, and 

 orange form may occur in either sex. Among the best 

 Papilionine mimics of the Planemas is Papilio cynorta 

 whose female is extraordinarily like the common 

 Planema epaea (PI. VII, figs. 5 and 10). The re- 

 semblance of the planemoides female of P. dardanus 

 to P. poggei has already been noticed. 



A striking feature of the African continent is 

 the frequency with which mimetic forms are found 

 among the Lycaenidae. As a rule the "blues" rarely 

 exhibit mimetic analogies, but in Africa there are 

 several species, especially those of the genus Mim- 

 acraea, which closely resemble Acraeines. Others again 

 bear a marked resemblance to certain small Pierines, 

 Citronophila similis from S. Nigeria for example 

 being extraordinarily like the common Terias brigitta, 

 a small bright yellow Pierine with black-edged 

 wings. 



A remarkable feature of the African continent 

 is the absence of the Pharmacophagus Swallow-tails. 

 Of such Papilios as exhibit mimicry, and as compared 

 with the total number of the group present the pro- 

 portion is large, the majority resemble one or other
