to each other, between the bark and the wood." The 

 name given it is the Tomicus exesus. SAY. 



Gurculio Pales. HERBST. 



(COLEOPTERA CURCULIONID^.) 



The larvae of this beetle is found under the bark of the 

 pine, sometimes doing much damage. Even the maturfe 

 insects prove destructive by puncturing the buds and tender 

 bark of the small branches, feeding upon the juice; the 

 young shoots break off or die at the wounded part, so 

 great is the injury. It is only when the larvae is found in 

 great numbers under the bark that the tree receives a 

 permanent injury. Woodpeckers prove of great assistance 

 in destroying them. Wilson, the ornithologist, describes 

 this insect when speaking of the ivory-billed woodpecker, 

 and urges the protection of the bird. 



The Buprestes Virginia, Drury, is the largest beetle we 

 have treated of infesting the pine trees. It measures from 

 eight-tenths of an inch to one inch or more in length. 

 The larva bores into the trunk of the trees, oftentimes 

 proving very injurious. 



According to Packard, the larvae of the Pine saw-fly, 

 Lophyrus abietis, Harris, are found upon the fir and pitch 

 pine. They are social in habit, and may be found in 

 considerable numbers on a single needle of the pitch-pine. 

 The larvae spin tough cocoons among the leaves, and the 

 flies appear in the spring. The larvae can be easily des- 

 troyed by showering them with a solution of carbolic acid 

 or whale oil soap. The eggs are laid singly in the side of 

 a needle of the pine; though sometimes an egg is inserted 

 on each side of the leaf. 



Mr. Riley has described the habits of the white pine 

 saw-fly, Lophyrus abbotii Leach. The flies appear in 

 June, and there is but a single brood of larvae, which 

 remain on the tree, in Illinois, until November, and 

 hibernate before changing to pupae.
