 and d represents the pupa within the cocoon. At e a per-

 is represented with its wings spread. At g a small apple 

 is shown, with the young larva just entering the fruit. In 

 many instances, when apple-trees are growing where the 

 soil is rich in apple-producing material, the expansion of the 

 fruit will often exceed the ravages of the larva that is eat- 

 ing its passage to the core. If they can not reach the core, 

 the fruit, in most instances, continues to grow, and the lar- 

 va dies. We frequently see apples that are imperfect and 

 much depressed on one side of the basin, the cause of which 

 is usually attributable to the working of a larva when the 

 fruit was very small. As the apple grew faster than the
