 (1) Peach-tree Borer — Buprestis divaricata : Say. 

 This derives its name from the fact that the wing- 

 covers are spread apart a little at the tips. " The 

 beetles are copper colored, covered with punctures. 

 They are from seven to nine-tenths of an inch in 

 length." The larvae bore the trunks of the peach 

 and cherry. When they are found in the tree, a 

 flexible wire should be run into the hole, so as to 

 stab the worm. 



(2) Snapping Beetle — Chgrsobothris femorata.
