THE I'KAK TIIHII'S. 9 incision, of the head Avitli its hriiiht red eves, l^ittlc by little, and swayinji; backward and forward, the larva forces itself out until about one-half of the body is exposed, when first the antenna^ and then one l)y one the ])airs of leo;s are made fi'ee fi-oni their I'estinu; position a(i;ainst the body.

From foin- to ten minutes are required for the insect to free itself from the egg. The young insect is almost transparent and the green chlorophyll ])articles taken into the stomach can ])e seen through the ])ody wall. Growth is rapid from the beginning. A very decided change takes place during the second larval stage (fig. 4). In about three weeks the insect reaches a size often larger than that of th fully matured insect. It then to feed, falls to the ground, and enters the ground by some crack or wormhole. It goes down from 3 to 10 inches, according to the structure and condition of the soil, the usual depth being about 4 inches. Upon reaching a secure depth, the larva hollows out for a tiny spherical or oblong cell or it finds an exceedingly small natural cavity and shapes this for its convenience. The completed chamber has a hard, smooth inner wall, and it is about one-twelfth of an inch long, or just a little longer than the insect itself.
