are rendered specially couspicuous by the interrupted black border to the bind 

 wings, the interruptions extending along the hind margin of the fore wings. A 

 white butterfly with such a border becomes an extremely conspicuous object, and 

 this appearance of Mylothris is mimicked, more or less perfectly, by species from 

 a number of Pierine genera, such as Nepheionia, Belonois, Callosune, &c. This is 

 usually explained as an example of true Batesian mimicry, but it is, perhaps, more 

 probable that the Pierince are very largely a specially protected group, many of 

 thfi genera of which, so to speak, combine their advfrtisements, and thus share 

 between them the loss of life which must necessarily ensue during the education 

 of each generation of their enemies. 



I think sufficient evidence has been brought forward to show that the theory 

 of mimicry, or rather of common warning (synaposematic) colours, which will 

 always be associated with the name of Fritz Miiller, may claim abundant examples 

 in Africa as well as in the other parts of the world in which it has already been 

 proved to hold.
