166 ARTICULATES: INSECTS. 



Pine Weevil, in the larva state, lives in the trunk of 

 the pine, in which it cuts passages in various direc- 

 tions. The Long-snouted Nut Weevil, in the larva state, 

 lives in nuts. The Plum Weevil, when shaken from 

 the tree, looks like a dried bud. This weevil makes a 

 crescent-shaped wound on the surface of the plum, in 

 which it lays an egg ; from the egg there hatches a 

 whitish grub, which burrows into the plum, even to 

 the stone. The Rice Weevil feeds upon rice, wheat, 

 and Indian corn. It is about one tenth of an inch 

 long, with two red spots on each wing-cover. 



LONG-HORN, OR CAPRICORN BEETLES. 



These beetles have very* long and generally curved 

 antennae. When we catch them they make a squeaking

sound, by rubbing together the joints of the thorax 

 and hind body. In the larva state they live in the 

 trunks of trees and in timber, and are called borers. 

 As they eat their way in the timber they fill the pas- 

 sages behind them with their cuttings, which the car- 

 penters call powder-post. Some, however, as the Ap- 

 ple-tree Borer, keep the end of their burrow open, 

 out of which they cast their chips. They remain in 

 the larva state from one to three years.
