CERATOMIA AMYNTOR 167 



In six days they molted for the third time, and were 

 unchanged, except that they had grown to a length of 

 one and a quarter inches. Four came out a dirty 

 greenish brown, with light brown marks. 



The first brood molted in seven days, the second in

It was just a week before the pupie came from the 

 larva-skins. They were an inch and three quarters

 a dark red-brown, showing no tongue-case, and had on
