they seem to me to be varieties of Polygama. None of the forms occur 

 here, but many times I have been called upon to identify them, which I 

 have done with hesitation. Last summer a lot of bred specimens were 

 sent me which contained all three of the forms, but the larvae seemed to 

 the one who bred them to be identical. Of course, this is not as con- 

 clusive as breeding from one brood of eggs, but from this and other 

 observations I should place them together. 



I append here three figures, one of Amasia, A.-S. (Fig. i), as it flies 

 in our woods in July. The second is a copy of Abbott's figure of Amasia 

 (Fig. 2). The third is a figure of Cordelia, Hy. Edw. (Fig. 3), as it also 

 occurs here in the same month. As to the latter, my first examples were 

 identified by Henry Edwards soon after he described the species, so that 

 I have no hesitation in thinking that I know his species. I have taken 

 both forms for a number of years and have never found any variation of

one towards the other. Amasia is rather a variable species, the variations 

 consisting in some being lighter than others, and in some showing a green- 

 ish tinge as in var. Virens. On the other hand, Cordelia varies but little. 

 As to which one Abbott had before him when he made the figure, I think 

 no one who sees these figures will doubt. I have shown these figures to 

 several who are well versed in the genus, and without hesitation they said 

 Amasia as I have it here and not Cordelia. Dr. Strecker's figure 12, plate 

 9, is a very good copy of either Abbott's figure or of a specimen of Amasia. 

 I have many times had Alabaime from the South for identification, 

 and I can see no reason for regarding it as a variety of Grynea. The
