THE LARVA. 
The white grub-like larva hatched from the egg@ at once begins feed- 
ing on the tender inside portions of the square, form, or boll into 
which the egg has been laid. It feeds here for its entire life period, 
protected from all exposure. In full-grown bolls these larvee are 
often found feeding inside the 
maturing seeds. The egg is 
occasionally deposited so late 
in the season that the larva 
barely has time to eat into the 
seed before the boll opens. 
Hence the cotton is sometimes 
gathered and ginned before the 
larva has become full grown, 
passed through the pupalstage, 
and issued asa weevil. Itcon- 
sequently often happens that 
adult weevils are found in the 
seeds later on. (See figs. 2 
: and 3.) 
Fic. 3.—a, Newly hatched larva in young square; )b, It requires fourteen to sev- 
nearly full-grown larva in situ; ¢, pups in young enteen days from the time of 
boll picked from the ground. (After Howard.) hatching far the darvasties 
come full grown. It is a white footless grub, with a brown head. 
When full grown it is from a quarter to three-eighths of an inch in 
length, usually slightly curved or doubled upon itself. 

THE PUPA. 
When the larva is full fed it passes into the third or pupal stage. 
Here it transforms into a robust, short, compact form, showing the 
wing pads, legs, and snout. The abdominal end is free and is wriggled 
about very actively when disturbed. It is white until just a short time 
before the weevil is ready to come out of this pupal transformation 
state. Then it turns darker and the weevil escapes or hatches. The 
time occupied in this stage is seven to ten days. After the weevil 
leaves the pupal skin it requires a couple of days to color and harden 
up and to appear, as does the adult weevil already described under that 
heading. When fully colored up, the adult eats a small round hole out 
of the square or boll it has been in all its lifetime, and escapes to the 
open air. . 
It should be carefully noted that the egg is laid nowhere else than 
in the squares, forms, or bolls. The larva grows and matures inside 
these, and there changes into the third or pupal stage. This stage is 
also passed in the same squares, as also the first few days of the adult 
stage. This is important, as will be noted from the recommendations 
based upon it further on in this report.
