species are often but poorly known. Records of the trees and 

 shrubs upon which the beetles occur are always valuable, and 

 especially so if it be ascertained that they have emerged from 

 such plants, or if they are bred from them. By carefully ex- 

 amining injured or fallen trees these beetles may often be found, 

 or their larvae and pupae be obtained. Many species also occur 

 during the summer upon flowering plants, especially trees and 

 shrubs, such as Elder, Sumach, Goldenrod, Spiraea, etc. The 

 smaller species, as well as some of the larger, may be most 

 successfully obtained by using a beating-net under the branches 

 of such trees as they infest. While nearly ever tree and shrub 

 is attacked by one or more species, the Maples. White Pine and 

 Hickory are most subject to their depredations.
