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 which came to the sugar were four Arthemis 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. Ent., IX., p. 140, Mr. Moffat states that Proserpina has been taken near 
Hamilton occasionally, and always in company with Arthemis. 
In Can. Ent., \ II., 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 
Artemis, is included, and said to be common, but neither Proserpina nor Ursula 
are mentioned. 
* 1 formerl T 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. Hall 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. 
I he western 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 
appears 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 m some regions, as m Michigan, probably overlaps. And wherever Proserpina 
appears there are found individuals banded almost as conspicuously as Arthemis, 
and from these there is a regular gradation to what has been considered a north¬ 
ern form of Ursula, showing no band or traces of one, and these last, as we <m 
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 throughout this broad 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 
ustrous 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 secondaries, and 
ie apex is of a light shade of brown, and often more or less suffused with a
