144 ENTOMOLOGICAL NEWS. [May, '03 



and although one larva died without tasting food, the others 

 were reared to maturity. One emerged on August 27th, the 

 other on August 31st, and both were females and umbrosa. 

 This I think is a very unusual occurrence. 



I might add that, while the appearance of almost every spe- 

 cies due after the first of June, was delayed from one to six 

 weeks, the broods of Feniseca tarquinius were thrown into the 

 most hopeless confusion of all. In this locality there are three 

 broods anually appearing at fairly regular intervals ; but last 

 season while collecting the larvae I found on the same day 

 (August ist) eggs, small, medium sized and full grown cater- 

 pillars, chrysalids and butterflies; on August 21st the same 

 state of affairs was noted except that no eggs were found and 

 fewer butterflies, and these all females. 



It seems to me that the coming season should be prolific in 

 captures of the unusual, especially among the hibernating in- 

 dividuals of such species of Polygonia as appear in distinct 



seasonal forms.
