with it has overcome the ravages to some degree 

 in most sections, and in some cases the farmers 

 have almost reached the original production. 



The cotton boll weevil is a member of the 

 beetle family. In size it varies from one 

 eighth to three eighths inches in length and 

 the breadth of its body is about one third its 

 length. The color varies from a light yellow- 

 ish brown to a chocolate brown. 



The members of the group of insects to which 

 the boll weevil belongs are characterized by 

 having part of the head in front of the eyes 

 greatly extended to form a long slender snout. 

 The snout of the boll weevil is slightly curved 

 and is about one half as long as from the head 

 to the tip of the body. The distinguishing 

 feature of the cotton boll weevil is two tooth- 

 like projections on inner side of the fore-legs, 

 at the lower end of the thigh, the inner or one 

 nearest the body being longer than the other. 

 There are four stages in the life of the weevil, 

 the egg, the larva, the pupa, and adult weevil. 



Three of these stages, egg, larva, and pupa 

 are passed inside the cotton square or boll. 

 The egg is deposited by the female weevil in a 

 cavity formed by eating into a square or boll.
