 Hampson. The insect 

 occurs in southern Texas, 

 Arizona, and Mexico. The 

 writer has a large series collected for him in the neighborhood of

This very common insect, which sometimes proves a 

 veritable plague by the depredations which it commits upon 

 the foliage of the Ampelopsis, 

 which is extensively grown in 

 our cities as a decorative vine,

 northern Atlantic States, and 

 ranges westward beyond the

 the larvae of this moth from the 

 vines with which his home is 

 covered.
