GENUINE SNOUT-BEETLEvS. 



Ill about a month it attains its full size, when it presents the ap- 

 pearance shown in Fig- 209, which represents the larva and the 

 pu])a highly niagnihed. Fig;. 210 shows an infested apple, the

"The larva is a soft white grub, nearly half an inch in length, 

 with a yellowish-brown head and jaws. Its body is much wrinkled, 

 the spaces between the folds being of a bluish-black color; there is 

 also a line of a bluish shade down the back. Having no legs, it is 

 incapable of much movement, and remains within the fruit it 

 occupies, changing there to a pupa of a whitish color, and in two 

 or three weeks, when perfected, the beetle cuts a hole through 

 the fruit and escapes.

"When feeding this insect makes a number of holes or punc- 

 tures, and around these a hard knot or swelling forms, which mucli 

 disfigures the fruit; pears, as well as apples, are injured in this 

 way. The infested fruits do not usually fall to the ground, as do 

 apples affected by the codling worm, but remain attached to the 

 tree, and the insect, from its habit of living within the fruit 

 through all its stages, is a difficult one to destroy. Picking the 

 affected specimens from the tree, and vigorously jarring the tree 

 during the time when the beetle is about, will bring it to the 

 ground, where it can 1)e destroyed in the same manner as recom- 

 mended for the plum curculio. F\)rtunately it is seldom found 

 in such abundance as to do much damage to the fruit-crop. In 

 Sf)Uthern Illinois, and in some ])ortions of Missouri it has proved
