234 THE COLOURS OF ANIMALS 



of Swallow-tailed Butterflies (Papilio) were also re- 

 sembled. He gives a list of eighteen examples of 

 mimetic resemblances from among the Swallow-tails 

 alone. Among these was an interesting case in which 

 the males of a Malayan species (Papilio paradoxd) 

 mimicked the males of one Euplcea (E. Midamus), 

 while the females mimicked the females of another 

 Euplcea (E. Rhadamantlms). A. special section of 

 Swallow-tails are also the objects of Mimicry in 

 South America. 



The African Papilio merope as an example of Mimicry 



By far the most remarkable example of Mimicry 

 is that alluded to in the passage quoted from Bois- 

 duval, and which has been worked out, together with 

 many other cases of Mimicry, by Mr. Roland Trimen 

 in South Africa. This wonderful example does not 

 appear to be sufficiently well known, although it is 

 excellently described and illustrated in Mr. Trimen's 

 paper, 1 from which this account and the figures upon 

 the coloured plate are taken. Each of the figures 

 has been reduced to half the natural size. 



2 Fig. 1 closely resembles the male, while fig. 2 re- 

 presents the female, of a beautiful pale yellow and 

 black Swallow-tailed" Butterfly (Papilio meriones) which 

 is found in Madagascar. The only marked difference 

 in colour between the sexes is the larger amount of
