(1) Vanessa antiopa (Linnæus), [Plate XXX], ♀ (The Mourning Cloak, The Camberwell Beauty).
This familiar insect needs no description. It occurs everywhere in the north temperate zone. Eggs laid in large masses on willows, poplars, and elms. There are two broods in the Middle States, the second hibernating under eaves and in hollow trees. Expanse 2.75-3.25 inches.
There is a rare variety of this insect in which the yellow border becomes broad, reaching the middle of the wings. Only two or three such “sports” are known, one in the possession of the author. There are some collectors who set great store by such “freaks” or “aberrations,” as they are called.

(2) Vanessa j-album Boisduval & Leconte, [Plate XXXI], ♂ (The Compton Tortoise).
No description is necessary as our figure will enable it to be immediately recognized. A close ally of the European Vanessa vau-album. Expanse 2.60-2.75 inches.
Larva feeds upon willows. Confined to the northern parts of the country, only occurring in Pennsylvania upon the summits of the higher mountains, and ranging thence to Labrador in the east and to Alaska in the northwest.
