material, "we may refer to the case of the tiny acorn moth, 

 which Mr. Riley tells us takes up its abode in the deserted, 

 worm-eaten acorn, feeding upon the crumbs left by the 

 3''oung 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 rohinioe; 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 ])ark 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 would be an excellent plan to 

 have a growth of golden rods near the locust grove. These 

 will toll the beetles in great numbers, when the}^ can be 

 plucked off and destroyed. In the middle states the locust, 

 which there tln-ivcs better than in the north, is often defoli- 

 ated by a leaf-mining ])eetle, 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
