The illustration shows the adult of the common round-headed 

 apple-tree borer, Saperda Candida, which attacks apple trees and 

 tunnels in the trunk near to the surface of the ground. It is 

 dark grey in color, with two white stripes along the back. 

 Three years are required to complete its life history. The only 

 sure remedy is to dig them out. Sometimes w^e can kill them 

 by injecting a little bisulphide of carbon in the tunnels and 

 stopping up the holes. This will kill them by su-ffocation.

 natural size. Eats the foliage of the apple and pear. 



Tlie apple-tree tent caterpillar, Clisiocampa Americana, forms 

 nests or tents on the trees in May. The young come out in 

 the morning to feed and later go back into the nest, where they 

 remain at night and in stormy weather. It sometimes does 

 considerable damage by defoliating trees. It is well to destroy 

 the nests if it can be done at a time when the young are in 

 the nests and before they have done much injury. This insect 

 can be readily controlled by spraying the foliage with Paris 

 green or arsenate of lead.
