a week later in Maine. The caterpillar state lasts about a 

 month, and the chrysalis state two or three weeks. It is 

 probable that while the majority of the moths appear in the 

 late summer or early autumn, according to the latitude of 

 the place where they live, a few may hybernate in the pupa

 England States." This suggestion seems to be strengthened 

 by the fact, which seems to be established, that in Australia 

 it emerges from pupa in March. 



Perhaps upon the whole it is as well that this species does 

 not appear able to effect a permanent settlement in these 

 Islands. 



Slight variations from different parts of the world have 

 received the names of saccharioora^ trifolii, anfica, connccta, 

 and separata.
