This is an European species attacking elm trees, which is now 

 quite abundant in this country, causing injury to small trees. The 

 females usually settle in the cracks of the bark, and are quite con- 

 spicuous. The young are born alive about the middle of June in 

 Connecticut. ' At first they settle along the veins of the leaves, 

 chiefly on the under side, and later return to the crevices of the 

 bark on the trunk and larger branches. There is one generation 

 each year. Spraying with kerosene emulsion is the remedy.
