THE MEXICAN COTTON-BOLL WEEVIL. 



Many of the weeds in the vicinity of the cotton fields are attacked 

 by different species of weevil's which may in some respects resemble 

 the boll weevil. Some of these weevils are of a general dark color and 

 have beaks with which to puncture their food plants. On close observa- 

 tion it will be found that the weevils which are discovered on other 

 weeds are breeding in those weeds. They are not the boll weevils 

 and will not attack the cotton. Many of these native weevils are also 

 found on the cotton plants at the nectar winch is produced by the 

 squares, blooms, and leaves. These weevils simply visit the cotton 

 plants in order to feed upon this nectar and do not injure the plant 

 in any way. The following list contains the names and references to 

 the habits of some of the most common weevils winch occur in and 

 about cotton fields:
