and deserve to be cherished and protected for their services. Rose 

 bugs are also eaten greedily by domesticated fowls ; and when they 

 become exhausted and fall to the ground, or when they are about to 

 lay their eggs, they are destroyed by moles, insects, and other ani- 

 mals, which lie in wait to seize them. Dr. Green informs us that a 

 species of dragon fly, or devil's needle, devours them. He also says 

 that an insect which he calls the enemy of the cut worm, probably 

 the larva of a Carabus, or predaceous ground beetle, preys on the 

 grubs of the common dor bug. In France, the golden ground beetle, 

 ( Carabus auratus,} devours the female dor or chafer at the moment 

 when she is about to deposit her eggs. I have taken one specimen 

 of this fine ground beetle in Massachusetts, and we have several other 

 irinds, equally predacsous, which probably contribute to check the 

 increase of our native Melolonthians.
