ing thicker towards the outward termination, are eleven 

 feelers, composed of joints. The feet are strong, pro- 

 vided with four jointed toes. Both the perfected insect 

 and larvae live in different portions of plants, which, 

 partly fresh and partly withered, are yet not really de- 

 cayed. They make a cocoon of resin or silk, into which 

 they retire to accomplish their metamorphosis. They do 

 great injury in gardens, forests, and fields. 



The Beech Beetle or Springer (orchestes fagi), plate 

 24, fig. 1, is one-tenth of an inch in length ; black, with 

 feelers of reddish-brown ; segments of the legs the same ; 

 wing-coverings, or elytra, arranged in rows and dotted. 

 Their legs are constituted for leaping, and they live on 

 the beech trees, where they devour the leaves and fruit. 



The Orchard Beetle (anthonomus pomorum), is rather 

 more than a line in length ; the body enveloped in a coa.t 

 of grayish down ; general color brown ; covering of the 

 back white ; and feeds on the blossoms of the fruit trees. 

 The larvae, which are peculiarly abundant in wet sea- 

 sons, live in the buds, mostly choosing those of the 

 weaker trees, to which they do great injury. Their 

 metamorphosis takes place at the end of May, after the 

 larvse have destroyed the germs of fruit. 



The Pine Beetle (rhynch genus pini) is above half an 

 inch in length, with a very long, thick trunk, and short 

 feelers ; of a brown color, dotted and striped with black. 

 It is very injurious to pine forests, particularly to young 

 or sickly trees, as it pierces the bark and buds with its 

 trunk. The larvae make great havoc, as they penetrate 

 to the alburnum or sapwood. The best way of exter- 

 minating these vermin is to cut down the declining trees, 

 clear off all fallen timber from the ground, and spare the 

 certhia, or creepers, which are their natural enemies.
