112 THE CANADIAN ENTOMOLOGIST. 



list of those taken at Grinnell, la., 1870, in Am. Ent, 2, 175 ; also a 

 recent list of butterflies of Illinois by Mr. C. E. Worthington, in Can. 

 Ent. Manuscript lists of butterflies of Illinois and Nebraska have been 

 in my possession for some years, made by Mr. G. M. Dodge. Prof. S. H. 

 Peabody also wrote me of the occurrence of Alope in Wisconsin, and sent 

 me examples so labelled, which were taken by him at Madison. I have 

 written to the authors of these lists and had replies from each one, and in 

 most cases examples of the butterflies called Alope were sent me. And 

 in every instance what had passed as Alope was what I call Nephele, nearly 

 always female, a little off type, in some cases considerably so, but never 

 closely approaching the typical Alope. There has in no case been a clear 

 colored yellow band, but always either a slight discoloration about the 

 ocelli on fore wing, or a more or less hazy, ill-defined, obscure yellow 

 area, such as appears frequently in the dimorphic belt in New York, and 

 which there represents the intergrades between Alope and Nephele. In 

 the west, they are ?iot intergrades, because there is no Alope to intergrade 

 with, but what I should call examples of reversion. I limit the name 

 Alope to the typical form. These intergrades, or what would be so char- 

 acterized in the dimorphic belt, are never found where Alope flies alone, or 

 before it has entered the belt ; but they appear in greater or less degree 

 wherever Nephele flies, whether in Canada or Illinois and westward. Even 

 in California, in Boopis, we find occasional examples of same character. 



Dr. J. P. Hoy, of Racine, Wisconsin, writes thus: " Nephele is the 

 most abundant butterfly on the prairies four miles west of Racine. I 

 have taken many hundreds and never saw a single Alope. I took a num- 

 ber of Alope in Berkshire Co., Mass., some years ago, and they are all I 

 have. The Wisconsin specimens correspond precisely with those in 

 Ills. When Professors Kirtland and Baird visited me in 1859, we travelled 

 over a considerable portion of the State, taking specimens of natural 

 history. Prof. Kirtland was greatly interested in our species of Satyrus. 

 He first thought it was Alope, but under a peculiar form. But when we 

 found a lot of the larvse he said it was not Alope. After, he wrote me that 

 it was Nephele, Kirby. You may say that Alope is unknown in Wisconsin, 

 and that the form Nephele is greatly abundant on the prairies, the most 

 common species in midsummer." 



I asked Mr. Putnam whether he had ever seen a typical Alope in Iowa, 

 and he replied that he never had, adding : " those which I considered 

 Alope in my list are probably intergrades " ; and the examples which Mr.
