The act of preparing the cavity and depositing the egg appar¬ 
ently requires considerable energy, for, after depositing an egg, 
the weevil requires a period of rest before repeating the operation. 
SEALING THE CAVITY. 
After the egg has been deposited, but before the ovipositor has 
been withdrawn, the substance with which the cavity is sealed 
may be seen flowing through the translucent ovipositor into the 
cavity. The ovipositor is then withdrawn, and its trowel-like 
tip is used to work the fluid into place. This consists of a thorough 
tamping of the material and smoothing of the surface, and con¬ 
tinues until the fluid solidifies. This process being completed, 
the weevil, without changing position, usually deposits a second

mass of material over the first. The second discharge is much 
less plastic than the first, and is not usually very thoroughly worked 
with the ovipositor, except when the surface of the first discharge 
lies below the surface of the corn. Frequently a third mass of 
material similar to the second, but much smaller, is discharged. 
This is rarely tamped. After this, the weevil pays no further at- 
tion to the egg, but immediately abandons the place. 
DESCRIPTION OF THE PLUG. 
The plug that seals the cavity may be described as a rather 
uneven disc-shaped body about .12 mm. thick, the diameter cor¬ 
responding to the diameter of the mouth of the cavity. The inner 
surface is somewhat hemispherical, with a minute pit in the centre
