DESCRIPTION. 



The egg was not fouud, it being too late in the season. 



The larva is represented in the accompanying illustration (Fig. 30, c). 

 It measures 6 to 7'""^ when curved, 9 to 10""" Avhen nearly straightened 

 out. It is a curved, whitish grub, of robust form, tapering a little at 

 each end, more so at the anal end. The head has a brownish or yel- 

 lowish tinge. 



The pupa, shown in the figure at &, measures from 4 to 7""". It is 

 entirely whitish, with the eyes black. The elytra, when partly formed, 

 are bluish. More mature pup;B are tinged with brownish on the tho- 

 racic dorsum and beak. 



The adult is represented at a. It measures 5""" in length. Xewly 

 transformed weevils in the bolls are reddish. When first issued, they 

 are usually covered with a yellowish bloom, which becomes grayish as 

 they mature. 



In the eastern and northeastern districts ot Coahuila, Mexico, this 

 insect is kuown as the ^'picudo," and in the infested regions of Texas 

 as the " sharpshooter," in allusion to the effect produced by it upon 

 the bolls, small exit holes through which the beetles issue being left in 

 them.
