I have examined a number of specimens of Dionyza, Hy. Edw., from 

 Arizona, through the kindness of Mr. Poling, and see no reason for calling 

 it a variety of Piatrix, Grote. The wings are constantly lighter and 

 somewhat differently marked, and it is a smaller insect. 



Desdemona, Hy. Edw., is quite a distinct form from Delilah, Strecker. 

 While the mesial band of hind wings shows that it belongs to the same 

 group, the general aspect and markings of the fore wings are quite 

 different. The Eastern form Delilah has the general tone of the fore wings 

 a distinct brown, while the Western form is gray, with lighter hind wings. 

 All the Eastern forms I have seen agree with Dr. Strecker's figures, 

 plate 1 1. 



I do not know Henry Edwards's species Calphurnia and Andromache, 

 except in the descriptions. As to Badia and Coelebs, there is quite a 

 difference of opinion. From all the examples I have seen, I should regard 

 them as distinct. Mr. C. M. Dodge, of Louisiana, Mo., says that, on the 

 authority of his collectors, they fly at different times. I have seen no 

 intergrades, and will leave them as distinct till breeding settles the 

 question. 



Abbreviatella and Whitneyi are very close, but from all the examples 

 that have come to me, they seem distinct. They fly at different times, and 

 Abbreviatella is the more northern form. I would suggest that Mr. Dodge 

 should make an effort to breed Whitneyi, which occurs in his locality, 

 and thus settle the question. 



It seems to me that there is little excuse for the name Blandula. 

 Our specimens of Polygama agree as well with Guenee's figure and 

 description as we can expect of any of the figures and descriptions of the 

 period in which they were made. With regard to Cratcegi and Mira,
