M ORDER COLEOPTERA. 



From the great and increasing value of the forests in New- York and Pennsylvania, it 

 beoomes necessary to direct attention to these destroyers, that proper care may be taken to 

 prevent their increase. Although living trees are subject to attack, these insects have the 

 peculiarity of flocking to recently cut timber. On this account, infected trees should be 

 out down and the bark subsequently removed and burnt, and the wood cut up and applied 

 as fuel, turned into charcoal, or immersed in water. Some European authors contend that 

 healthy trees are not attacked by these insects ; and that when the attack has been com- 

 menced, it is an indication that the tree is in a state of incipient decline.
