LBIENITIS I. 



which last the blue flush is much less than usual in examples here, and the two are 

 scarcely if at all distinguishable from each other. Therefore I cannot say that 

 all these Milford examples are not Proserpina; and indeed I do not know where 

 Proserpina ends and Ursula begins, though a typical example of each is distinct 

 enough. Mr. Scudder, in the report before cited, speaking of Ursula [Asbjanax), 

 sa3^s : "It is tolerably abundant in the southern parts of New England, and 

 occurs about as fir north as the annual isotherm of 4:5% the northernmost points 

 recorded being Did din and Milford, N. H." 



Arthcmis must rarely cross the southern line of New Hampshire, or of Ver- 

 mont except at the Hoosac Mountains, which are a continuation of the Green 

 Mountains. Dr. Harris states that it is rare in Massachusetts; and Prof. H. W. 

 Parker, of Amherst, writes that he has never seen it in his district, or on Mounts 

 Tom and Holyoke, or on the hills about Chester. 



Mr. Anson Allen, of Orono, central Maine, says, " Arthemis is common here, 

 but I have never known of Proserpina being taken. Ursula is not found 

 here." 



Mr. H. H. Lyman, Can. Ent., VI., p. 38, speaks of Ursula {Ephestion) as bav- 

 in"- been taken at Portland, Me. ; but I learn from him that he is now satisfied 

 that the butterflies were Proserpina. 



To the eastward, Proserpina is recorded by Rev. C. J. S. Bethune, Can. Ent., 

 II., p. 55, as having been taken in Nova Scotia. 



Mr. Robert Bunker, of Rochester, N. Y., says that Proserpina has not been 

 taken in that part of the State, so far as he knows, but that Arthemis is taken 

 about Rochester every sunnner. Also that Ursula is not common. 



At Albany, N. Y., which is nearly in the latitude of the southern line of Ver- 

 mont and New Hampshire, and is half a degree north of the Catskills, and not 

 more than thirty miles from them, Arthemis- is usually rare, but in some sea- 

 sons has appeared in considerable numbers, according to Mr. Lintner. He has 

 sent me two males of undoubted Proserjnna, with traces of the band on both sur- 

 faces, and another like these, but with no trace. As these graded from Proser- 

 pina to what seemed to be Ursula, Mr. Lintner was led to the same conclusion 

 that other observers had reached, that Ursula orginated with Arthemis, through 

 Proserpina. This apparent Ursula is precisely like the imbanded examples 

 from Milford, with the coloration of under surface as in Proserpina. 



Mr. Robert M. Grey, residing at Kenwood, near Albany, writes that he has 

 taken examples of Proserpina three miles below Albany in company with Ur- 

 sula. And of three males sent me by Mr. Grey, one was somewhat banded, 

 while the other .two showed no trace of the band, and were of same type as the 

 supposed Ursula of Mr. Lintner. Mr. Grey states further that he has taken Proser-
