IT MUST XUT BE <ONFU8ED WITH THE SHARPSHOOTER. 



In Mexico the insect is known to cotton growers as the ''^n'cMf/o," and in the 

 Brownsville region cotton planters have named it the "sharpshooter." From the 

 fact that this term has been used by the Brownsville cotton planters, some confusion 

 has arisen among planters living farther north, and many of them have supposed 

 that the insect is nothing but a species which has beeu known for many years in

Texas, and to which this same popular name of "sharpshooter"' has beeu applied. 

 In general, it may be said that whenever bolls or squares have been pierced by any 

 insect, and wilt in consequence, the work is called "sharpshooter work," not only 

 in Texas, but in Louisiana, Mississippi, and other portions of the cotton belt. 

 While several insects are engaged in this so-called sharpshooter work, the most 

 abundant one is that shown at fig. 3. This is the so-called "glassy-winged sharp- 

 shooter" (Homalodisca coagnlafa), belonging to an entirely different group of insects 

 from the Mexican cotton-boll weevil. 



The glassy-winged sharpshooter has been present in Texas cotton fields ever since 

 the cultivation of cotton began, since it was originally not a cotton insect, but 

 fed upon the poplar tree. The Mexican cotton-boll weevil is not only quite a dif- 

 ferent insect, but it is a far more dangerous one. It is much more abundant and its 

 attacks upon bolls and squares are much more serious, since not only are the bolls 

 punctured with the beak, as is the case with the glassy-winged sharpshooter, but 

 eggs are inserted and larv;e hatch, which feed upon the interior substance.
