die of each wing there is a pale band edged with zigzag, dark 

 brown lines. The larva lives upon apple, cherry, oak, birch, 

 maple, and ash. When full grown it measures two and 

 one half inches in length and one half inch in breadth. 

 The upper side is slate-gray, mottled with black, with two 

 transverse scarlet bands, one on the second and one on the 

 third thoracic segments. There is a black spot at each end 

 and in the middle of each of these bands. The larva is 

 found during July and August. It is said that the cocoons 

 are attached to limbs like those of Tolype ; but the larvae of 

 this species which we have bred made their cocoons between 

 leaves, or in the folds of the muslin bag enclosing the limb 

 upon which they were feeding. The species passes the 



winter in the pupa state ; 

 iflis and the moth appears in 

 Y' June, when it lays its 



eggs upon the leaves of 

 « the trees it infests.

The Skippers. 

 The Skippers are so 

 called on account of their 

 peculiar mode of flight. 

 They fly in the daytime 

 and dart suddenly from 

 place to place. When at 

 rest most species hold the 

 wings erect in a vertical 

 position like butterflies; 

 in some the fore wings 

 are thus held while the 

 hind wings are extend-
