REMEDIAL TREATxMENT. 



It lias been stated that hand picking can be made to 

 check the injuries of the small beetle last mentioned, but 

 to anyone who has witnessed its attacks in eastern Ken- 

 tucky this will seem incredible . The larger part of the 

 leaves of all the trees of a neighborhood may be occupied 

 by mines made by one or more of the above insects. 

 Since they are ordinarily concealed within the leaves it 

 might seem that it would be impossible to reach them by 

 spraying, but when it is remembered that this method 

 has proved very satisfactory in dealing with the codling 

 moth, and that the adults of the beetles feed to some ex- 

 tent on the leaves, it will not appear impracticable. I 

 am inclined to believe it can be made to answer the pur- 

 pose if it is supplemented by raking up and burning the 

 fallen leaves in the fall of the year, so as to catch the 

 species which spend the winter among them. 



The liocust Leaf-Skeletonizer. 



{Gelechia pseudacaciella) . 



This is another moth closely related with the three 

 leaf miners mentioned above, which, associated witlj them 

 or alone, has a very injurious effect on the trees. The 

 young of this is larger than the others, cylindrical, with 

 striped body, and lives between the leaflets, which it 

 fastens together with silk, and then gnaws away the sur- 

 face of the leaf, exposing the skeleton. It has proved 

 most injurious during August and September. 



The same treatment is to be recommended as for the 

 preceding. 



The LiOcust Skipper. 



{Eudanuis tityrus). 



The skipper of the black locust is a brown butterfly 

 with wing expanse of a trifle less than two inches, and
