It seems to me that this form is very primitive. 



I saw in some unpublished draw^ings of Prof. J. F. van 

 Bkmmelen after specimens of Pajtilio fjodalinus from the collec- 

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

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

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

 r. suproidigmalis, r. siibdormlis sup. and im/., r. prostigmalis, 

 r. jtoststigmalLt and r. infrantigimdis. The presence of v. subdor- 

 gaiis inferior and of v.prosfigmalis 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 tubercle stands in the position of v. dorsalLt. Between the 

 stigma and this tubercle there are two spots which therefore 

 agree with r. suprastigmalis and r. dorsolateral is. So here too a 

 r. 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 r. prostig malts, v. jwststigmalis ^ v. basalts and 

 often V. pedaiis. 



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

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