PL. XXXI 



(2) Vanessa j-album Boisduval & Leconte, Plate XXXI, cf 

 (The Compton Tortoise). 



No description is necessary as our figure will enable it to be 

 immediately recognized. A close ally of the European Vanessa 

 van-album. Expanse 2.60-2.75 inches. 



Larva feeds upon willows. Confined to the northern parts 

 of the country, only occurring ift Pennsylvania upon the sum- 

 mits of the higher mountains, and ranging thence to Labrador 

 in the east and to Alaska in the northwest. 



(3) Vanessa milberti Godart, Plate XXXII, 9 (Milbert's 

 Tortoise-shell). 



Easily distinguished by the broad yellow submarginal band 

 on both wings, shaded outwardly by red. Expanse 1.75 inch. 

 The larva feeds upon nettles (Urtica). 



Found at high elevations in the Appalachian highlands, 

 ranging northward to Nova Scotia and Newfoundland, thence 

 westward to the Rocky Mountains and the Pacific Coast, its 

 distribution being determined by temperature and the presence 

 of its food-plant, though its distribution seems to be more de- 

 pendent upon climate than upon food, as nettles abound in the 

 Southern States, where the insect is never found.
