Ranges from Nova Scotia to Alaska and southward as far as the mountains of the Carolinas.
(2) Brenthis montinus Scudder, [Plate XVII], Fig. 3, ♀, under side (The White Mountain Fritillary).
Upper side fulvous, the wings at base darker than in B. myrina, the black markings heavier. Hind wings below much darker than in B. myrina, the silvery spots being quite differently arranged, the most conspicuous being a bar at the end and a round spot at the base of the cell of the hind wing. Expanse, ♂, 1.50 inch; ♀, 1.75 inch.
PL. XVIII
A small species living on the summit of Mt. Washington, New Hampshire, where a little colony has survived the glacial epoch, when the northeastern parts of the United States were covered with glaciers, as Greenland is to-day.
(3) Brenthis bellona (Fabricius), [Plate XVIII], ♂ (The Meadow Fritillary).
The only species of the genus, except B. myrina, found in the densely settled portions of the continent. Easily distinguished from myrina by the absence on the under side of the wings of the silvery spots, which make the Silver-bordered Fritillary so attractive. It is generally found upon the wing in the late summer and the fall of the year. In Pennsylvania it may be found when the asters are in bloom.
Common throughout Canada and the northern United States as far west as the Rocky Mountains and as far south as the Carolinas. Expanse 1.65-1.80 inch.
