of about one half inch ; the fore wings are dull yellowish or 

 greenish-brown with irregular Hghter markings crossing the 

 wing obhquely ; the hind wings are ashy brown. The eggs 

 are unknown. There are probably two broods annually, the 

 winter being passed in the egg state. While generally dis- 

 tributed over the Eastern states, this insect rarely causes notice- 

 able damage ; it also feeds on the wild blackberry, hazel, meadow 

 sweet and hickory. 



In small plantings this insect can be controlled by hand- 

 picking the infested tips and crushing the larvae. On a larger 

 scale it would be more economical to use some arsenical spray 

 when the larvae first appear in the spring.

The Blackberry Phyllid 

 Trioza tripunctatd Fitch 



This jumping plant-louse, a near relative of the pear psylla, 

 occurs in the Atlantic states from Virginia to Maine. It has 

 been recorded as injuring the cultivated blackberry in New 

 Jersey and Maine, and on Long Island. Its native food-plant 

 is the wild blackberry. Its reported occurrence on pine is 

 doubtless purely accidental. 



The adult insect is about ^ inch in length; the body is 

 yellowish-brown, the eyes dark brown and the wings marked 

 by three yellowish-brown bands. The insect hibernates as an 

 adult. The flies appear on the blackberry soon after growth 

 starts in the spring and deposit their minute, Hght yellow eggs 

 in the pubescence of the leaf petioles and young canes. On 

 Long Island adults, eggs and newly hatched nymphs were
