attacked by this insect, which causes great havoc before it is 

 discovered. Little can be done in this case, and it is better 

 not to plant the infested land or land near it with straw- 

 berries again for some time. 



It may be observed that the Otiorrhynchus picipes, with its 

 allies Otiorrhynchus sulcatus and Otiorrhynchus tenebricosus, is 

 one of the troublesome insects of which the numbers and 

 ravages have materially increased in late years, probably 

 owing to the extended cultivation of fruit trees. 



The Fruit Tree Beetle [Scolytus rugulosus)* 



1. Beetle magnified; line showing natural length. 2. Larva, natural Isize, and 

 much magnified. 3. Piece of apple branch, showing holes in bark made by the 

 beetle, and channels made in the wood. 



This little beetle has been somewhat troublesome lately, 

 and shows a disposition to increase. It may be that on 

 account of its small size it has escaped observation, and its 

 mischief may have been attributed to other causes, but it 

 certainly is much more in evidence than formerly. Not only 

 has it attacked apple, pear, and plum trees, but peach and 

 nectarine trees have also been injured by it, as well as 

 flowering shrubs, in gardens, of the Ma/us and Prunus tribes.
