ORIGIN AND DISTRIBUTION. 



The green-striped maple worm is a native North American species 

 and is more abundant in the West than in the East, although it enjoys 

 a considerable range. It abounds especially in Kansas, Nebraska, 

 Missouri, Illinois, and Iowa, occurring also in the Gulf States, occa- 

 sionally doing considerable damage in Mississippi. It extends some- 

 times in injurious numbers North and East, and has attracted some 

 attention by its ravages in West Virginia, the District of Colum])ia, 

 New Jersey, and in a limited portion of New York State. Instances
