DESCRIPTION. 
The egg was not found, it being too late in the season. 
The larva is represented in the accompanying illustration (Fig. 30, c). 
It measures 6 to 7 mm when curved, 9 to 10 mm when 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 b 7 measures from 4 to 7 mm . It is 
entirely whitish, with the eyes black. The elytra, when partly formed, 
are bluish. More mature pupae are tinged with brownish on the tho- 
racic dorsum and beak. 
The adult is represented at a. It measures 5 mra in length. Newly 
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 known 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.
