The selvage edge of the wire netting should be used for the top of the cage and care should be taken that the circumference at the top and the bottom are the same. A cover similar to the ones used on the glass jars may then be placed on the top of the cage. These cages should be set 8 inches in the ground. After the larvae become full grown they de- scend into the ground and form their pupal chambers Cages of this.

(From Burgess.) sort should not be disturbed until the following spring. For hiber- nating quarters for beetles, boxes with bottoms made of wire screen can be used (PI. IV). They should be sunk into the ground from 18 to 20 inches, the earth inside the box being the same level as that on the outside. A hinged cover provided with wire netting should be placed on the top of the box and if convenient this cover should be padlocked so that the contents of the box will not be disturbed. Beetles may be placed in hibernation in cylinders (fig. 3) made of galvanized iron wire having a j-inch mesh. These can be constructed in the same manner as the small cylinders already mentioned. If larvse are to be placed in these cylinders it will be necessary to line them with fine wire screen in order to prevent their escape. This.
