LIMENITIS I. 



last seven or eight years I have found Proserpina in company with Arthemis, but 

 they are never plenty. Four years ago, 2d July, I tried sugaring in the day- 

 time, and among the insects Avhich came to the sugar were four Arthcin/s and 

 one Proserpina. On the tree one of the Arthemis was trying to mate with the 

 Proserpina, when I disturbed them." Hamilton is about fifty miles to the south 

 of Toronto, and nearly in line with the southern boundary of Vermont. So in 

 Can. Eut., IX., p. 140, Mr. Moffat states that Prosetpina has been taken near 

 Hamilton occasionally, and always in company with Arthemis. 



In Can. Ent., VII., p. 208, is a list of butterflies taken at Godbout River, on 

 the north side of the lower St. Lawrence, in the seasons 1873 and 1874, in which 

 Arthemis is included, and said to be common, but neither Proserpina nor Ursula 

 are mentioned. 



I formerly received a large invoice of butterflies collected by Mrs. Christina 

 Ross, at Fort Simpson, Mackenzie's River, and among them were many Arthemis, 

 but no Proserpina. But to the west of Fort Simpson, Mr. Dall did not find the 

 species on the Yukon River. Nor did Mr. Crotch meet with it in British Colum- 

 bia. I have never seen an example taken in the Rocky Mountains, and I think 

 the statement of Mr. Reakirt, Proc. Ent. Soc, Phil., VI., p. 143, that Arthemis 

 has been taken in Colorado, must be erroneous. 



The westerir limit of the species seems to be to the east of the Rocky Moun- 

 tains, and the southern coincides nearly with latitude 43°, but where high moun- 

 tains cross that line the limit lies a degree or two farther south. Proserpina 

 appeal's in certain localities along, the southern area between latitude 44° and 

 43°, and in the Catskills, 42°. 



The southern limit of Proserpina coincides with the northern limit of Ursula, 

 and in some regions, as in Michigan, probaljly overlaps. And \\\\qi'&\qv Proserpina 

 appears there are found individuals banded almost as conspicuously as Arthemis, 

 and from tlrese there is a regular o:radation to what has been considered a north- 

 em form of Urmila, showing no band or traces of one, and these last, as we go 

 south, grade into the typical Ursula. Below the line of Arthemis there is a belt 

 of several degrees of latitude in which many Ursula closely resemble Proserpina, 

 with the exception of the band. In other words, the northern form of Ursula 

 lives througliout this liroad belt, side by side with the southern form. The former 

 are blacker on upper side, the latter are suffused with blue or green, and the 

 lustrous area is not confined to the margins of secondaries, but often runs quite 

 to the base. The former have the under surface either dark or light brown, run- 

 ning into ferruginous, and the apex of primaries is of the same hue with second- 

 aries. In the latter a blue or green sheen hides the ground of secondai'ies, and 

 the apex is of a light shade of brown, and often more or less suft'uscd with a
