THE FALL CANKER-WORM. 



Anisopteryx pometaria, (Harris.). 



This species was considered and illustrated in Station Report, 

 1888, to which the reader is referred for an account of the life 

 history and remedies. We expressed there a want of information 

 regarding its distribution in the State and damages. Sioce then 

 we learn it is widely distributed and does considerable damage to 

 the foliage of orchard and shade trees. About Orono it has 

 steadily increased for the past two years and this season did con- 

 siderable damage. We think that by spraying with Paris greeu or 

 London purple in the usual way, when the worms are small, they 

 could be readily destroyed. This worm is known by the farmers 

 about Orono as the "Green Inch-worm." Last November we 

 received the following letter, which with the answer, we place on 

 record.

 F. L. Harvey : 



Enclosed find specimens of Lepidoptera, Anisopteryx, I think 

 female, with eggs accompanying. They are to-day found in 

 large numbers on the outside of the froqt door of my dwelling 

 house in this city. 



Are they A. eseularia or A. pometaria? I was not aware before 

 that they deposited their eggs oq buildings. Perhaps they are a 

 new insect. Can you tell ? 



Haste, 



Geo. E. Brackett. 



Mr. Geo. E. Brackett : 



Dear Sir: — Your letter containing insect specimens was 

 received during my absence from home. It now claims attention. 

 The specimens enclosed are the females and eggs of Anisopteryx 

 pometaria, Harris, the Fall Canker-worm. This species usually 

 deposits its eggs upon the branches or twigs of trees. The 

 females being wingless, when they emerge from the ground,
