gives an account of exceedingly interesting results he had obtained 

 in breeding this insect, known under the names of Papilio Ajax, 

 Telemonides, and MarceJhis. This is a very complicated case, 

 Dimorphism and Horeomorphism existing in the same species Mr. 

 Edwards uses the old name of Ajax to include all the variations; 

 tvaJskii, and its sub-variety ahloUii, for the spring emergence, and 

 retains the name of telemonides for the intermediate fonn, and 

 that of marcellus for those of summer emergence. 



In conclusion I have to add that in each of the classes I 

 could have given many more instances of the different conditions 

 of variation, but I have restricted myself to a few cases only, 

 which I deem sufficiently marked to illustrate the subject.
