especially near the ground. So destructive is this pest in some 
regions as to have caused the abandonment of peach growing. 
ACgeria tipuliforme. 
The currant borer, JEgeria tipuliforme , is scarcely less destructive 
than the preceding, and, as its name implies, the larva bores in the 
stems of tiie currant. The larva feeds on the pith of the plants, 
causing the leaves to turn yellow and eventually the plant to die. 
The moth is smaller than the preceding, expanding about three- 
quarters of an inch, is blue-black in color, the wings being trans¬ 
parent, with a coppery colored bar at the tips of the forward pair. 
The shoulder covers and three lines across the abdomen are yellow. 
The moth makes its appearance in June. 
Ageria pyri. 
A small species, whose larva bores under the bark and in the 
young wood of the pear tree, is JEgeria pyri. The insect expands 
half an inch. Its general color is purplish-black above and yellow 
beneath ; but the wings are transparent, with a band of copper-brown 
at the tips of the forward pair, and the body is crossed with two nar¬ 
row lines and one broad band of yellow, while the fan-shaped tuft of 
hairs at the end of the abdomen is yellow.
