38 THE CANADIAN ENTOMOLOGIST. 



It should be added that the males approach each other more closely 

 than the females. 



Alcestis is quite abundant on the prairie west and north of this city in 

 July and /vugust ; it seems to be quite local, as examples taken a few miles 

 north in a timbered region are almost uniformly aphrodite. I have been 

 greatly surprised at the readiness with which a strong aphrodite upon the 

 prairie can be distinguished while on the wing from the surrounding 

 alcestis, owing mainly to a slight difference in its manner of night, which 

 resembles that of cybcle. 



The difference of time of the appearance of the sexes in alcestis 

 appears rather to exceed that in other species, the order of capture of the 

 first examples of the larger Argynnidce being as follows : Alcestis £ , 

 idalia £ , aphrodite £ , aphrodite % , cybele £ , cybele °. , alcestis % , 

 idaiia °. . 



The habitat of alcestis extends farther west and not so far south as that 

 of aphrodite. Since the publication of Mr. Edwards' Catalogue I have 

 received good examples from Michigan, and am informed that it has been 

 taken in New York. 



In faded examples of alcestis (Sept.) a faint shade is observable in 

 certain lights between the outer rows of silver spots on secondaries, but 

 broad and regular like the band of cybele, and not in the least resembling 

 that of aphrodite.
