3. — The dark Satyrus which inhabits Illinois and westward has gone 

 by the name of Nephele, though differing somewhat from Nephcle of the 

 east. I was struck by the difference between a series sent me by the late 

 Mr. Walsh from Galena, years ago and when I first began collecting 

 butterflies, and a series of Nephele taken in the Catskills, and I have 

 always kept the two apart in my cases, considering the Illinois form as at 

 least a well marked variety. Mr. Worth ington has recently written me : 

 " I have received a lot of Nephcle from New Hampshire and am surprised 

 at the difference between them and the Illinois Nephele." 



The males of this last are almost black, the ocelli are very small and 

 without rings. But in some examples there is a faint russet or yellowish 

 tint about the ocelli, and perhaps on the space between them. On the 

 under side the rings are russet or ochraceous, on both wings. The females 

 are almost invariably and uniformly dark, and only occasionally is there a 

 paler shade over the extra discal area of fore wings. Out of a number 

 of females I find but one in which there is a clouded yellow space about 

 the ocelli, and only three on which there are yellow, though hazy, ocellar 

 rings. Of 16 g , 14 have 6 small ocelli beneath, 1 has 5, 1 has 2. Of 

 19 °_ . 2 have 6, 2 have 5, 6 have 4, 2 have 3, 6 have 2, 1 has 1. This 

 form prevails exclusively to the Rocky Mountains. I have received it 

 from Nebraska, Montana, Colorado and New Mexico, but Alope is un- 

 known to me from that region. 



In Can. Ent., ix., 141, 1877, I gave the history of Nephele, bred from 

 eggs laid by a typical female from the Catskill Mountains, Hunter, N. Y. 

 In fall of 1878, I wrote to several correspondents for eggs, and by their 

 good will obtained many. Prof. Lintner and Dr. Bailey sent eggs of Alope 

 from Albany, N. Y. Rev. Mr. Hulst, with the zeal and kindness which 

 distinguishes him, crossed the rivers from Brooklyn to Hoboken, and
