material, we may refer to the case of the tiny acorn moth, 
which Mr. Eiley tells us takes up its abode in the deserted, 
worm-eaten acorn, feeding upon the crumbs left by the 
young weevil. The caterpillar “secures itself against in¬ 
truders by closing with a strong covering of silk the hole 
which its predecessor had made in its egress.” 
The locust tree has, among a dozen or more insects known 
to prey upon it, been nearly exterminated by the well- 
known “borer.” The beetle (Fig. 187, Clytus robinice; a, 
larva; 6, pupa) is known by its bright yellow trappings, 
and the yellow W on the base of its wing-covers. It is very 
abundant on the flowers of the golden rod in September. 
The beetle lays its eggs on the bark and the young borer

makes its way under the bark upwards into the wood, eject¬ 
ing the chips and castings through an orifice in the bark. 
Eternal vigilance should be the watchword in dealing with 
the locust borer. Its presence may always be known by the 
little pile of dust at its door, and a wire thrust up its burrow 
will destroy the worm. It w^ould be an excellent plan to 
have a growth of golden rods near the locust grove. These 
will toll the beetles in great numbers, when they can be 
plucked off and destroyed. In the middle states the locust, 
which there thrives better than in the north, is often defoli¬ 
ated by a leaf-mining beetle, a kind of Hispa. 
But the pride of our lawns and roadsides is the elm. 
This tree we regard with a special reverence. Not so the
