APPENDIX II 



The genus Papilio is a large and heterogeneous collection. 

 It was pointed out by Haase^ that it falls into three distinct 

 sections, of which one — the Pharmacophagus section — ^provides 

 those members which serve as models in mimicry; while in 

 the other two sections are found mimics, either of Pharma- 

 cophagus Swallow-tails, or of models belonging to other groups. 

 Though Haase's terms have not yet come into general use 

 with systematists, there is little doubt that the genus Papilio 

 as it now stands must eventually be broken up on these lines. 

 To say that one species of Papilio mimics another is therefore 

 somewhat misleading ; for the differences between the Pharma- 

 cophagus group and the other two are such as to constitute at 

 any rate generic distinction in other groups. For convenience 

 of reference a table has been added in which the various 

 Papilios mentioned in the text have been assigned to then- 

 appropriate sections, and referred to their respective models.
