Note 46 — Chapter VII

The only other experiments comparable with these on P. polytes are some made by Jacobsen on Papilio memnon in Java[46]. Here again there are three forms of female, one of which, laomedon, is something like the male, while the other two, agenor and achates, are quite distinct. Of these three achates, unlike the male and the other two females, is tailed, and resembles the species Papilio coon which belongs to the same presumably distasteful group as P. aristolochiae. These experiments of Jacobsen's are not so complete as the series on P. polytes, but Professor de Meijere and Mr Fryer have both pointed out that they are capable of being interpreted on the same simple lines.
