It seems to me that tliis form is very primitive. 



I saw in some unpublished drawings of Prof. J. F. van 

 Bemmelen after specimens of Papilio podalirius froni the collec- 

 tion Kallenbach (which I could compare with the original objects) 

 that the pigmental spots of the fuU-grown caterpillars are arranged 

 in a definite pattern. In my opinion they agree with v. dorsalis^ 

 e. supyastiguialis^ c. suhdormlis suj). and inf., r. prostiginalis^ 

 r. poststigmalis and r. infrastigmalis. The presence of v. subdor- 

 s(dis infenor and of v. prostigmalis is remarkable, as they do not 

 occur in Gruber's figures of instar I. 



On the pupa of Papilio machaon (J. F. van Bemmelen 1912, 

 fig. 5) a tiibercle stands in the position of v. dorsalis. Between the 

 stigma and tliis tubercle there are two spots which therefore 

 agree with r. suprastigmalis and v. dorsoJateralis. So here too a 

 c. dorsolateralis occurs on the pupa which is not developed on the 

 abdomen of the caterpillars. Further there are spots on the pupa 

 which agree with v. prostigmalis^ v. p)OststigmaUs y r. basalis and 

 often V. pedalis. 



As a larva, P. macliaon varies very much in pattern. In 

 most cases, however, the above mentioned spots are present.
