There has always been a fascination for me in breeding 

 from the egg Papilio ajax, and repeating in various combina- 

 tions Edwards' classical experiment with this species. Doubt- 

 less everyone who has bred this fly has noted the varied length 

 of pupation in individuals of the same brood, has had early 

 spring eggs produce one form in a few weeks, others of the 

 same brood bring forth another form in midsummer, still 

 others disclose imagines of a third form in the late fall and 

 some pass over one or even two winters and produce the dif- 

 ferent forms the second or even the third spring, summer or 

 fall. In a large series bred from eggs laid in June, 1902, which 

 gave walshii, telamonidcs and marccllus at appropriate periods, 

 I had- one pupa among others last over until April, 1903, when 

 it disclosed a biformed female, the left side of which had only 

 the small white spot at the end of the tail (shall I call it ajax
