COLEOPTERA. 73 



Some of the beetle pests whose enemies ought to be 

 protected, and whose effective destruction ought to be 

 sought with every appearance of the pests are : 



Fruit and grain weevils The Borers 



Rose chafers Flea beetles 



Potato beetles June bugs 



White grubs Wire worms 



Carpet beetles Cutworms 



Curculios Leaf chafers 



The elm-leaf beetle is one of the most destructive 

 enemies of forest trees, and it should be recognized and 

 destroyed wherever found. The beetle is yellowish with 

 some black spots on the thorax and one black stripe on 

 the inner edge of each elytron. The prosternum and the 

 legs are yellow; the remaining under parts are back. It 

 is about a quarter of an inch long. Its yellow eggs are 

 to be found on the under sides of the leaves in masses, and 

 these should be crushed whenever found. From these 

 eggs hatch larvae or grubs, marked with black or yellow; 

 these skeletonize the leaves, or eat out the green paren- 

 chymatous parts of the leaves, leaving the veins and part 

 of the epidermis. They then pupate, and when ready 

 to do this they crawl down the trunk of the tree and 

 burrow a short distance beneath the surface but close to 

 the roots, or rather to the trunk of the tree. The adult 

 beetle winters over, under old leaf piles, in other rubbish, 

 or in the hollows of trees. Domestic fowls, robins, blue- 

 birds, thrushes, cedar birds, and catbirds are the most 

 effective enemies in getting rid of these, pests, both in the 

 adult and the larval stage. There is always, in such 

 cases, some effective bird ally which can be relied upon to 

 accomplish the destruction of the insect pest. Encourage,
