Up to the present time, the red spider has not been 

 sufficiently abundant to render the application of insecti- 

 cides necessary. 



THE BOLL WEEVIL (Anthonomus grandis, Boh.). Coleoptera. 



The boll weevil of cotton is not known in the Lesser 

 Antilles, and it is greatly hoped that it may never be in- 

 troduced. Since this insect made its entrance to the United 

 States from Mexico in 1894, it has developed into one of the 

 most serious pests on record, and there seems to be no 

 possibility of stopping its steady progress eastward to the 

 Atlantic Coast. 



The accompanying figures (58 and 59) are given 

 in order to show what the insect is like in its different 

 stages of growth. The fine line in Fig. 58 shows the exact 

 length of the weevil.
