protiudiii^ from llic Itaik. it is well to investigate with a stifV pin. and if a cavity 

 is found, to extract the occupant before he goes so deeply into the wood as to be 

 beyond oiir voaeh. A little time spent each fall in this way will be well repaid by 

 increased vindr of our orchards. 



THK CIIKUKY LEAF-BEKTLK. 



(Galcrucella cavicollis, Lee.) 



The cherry leaf-beetle is an interesting species, because of its known change of 

 habit. It ordinarily feeds on pin cherry and was found in numbers on that host- 

 plant at Au Train Falls. At least twice it has attacked the cultivated cherry in 

 Michigan, each time doing appreciable injury. Mr. (',. C. Davis mentions it in the 



ChiMiy Leaf-Beetle (Galerucella cavicollis), from author's Bulletin IGO. 



Report of the Michigan Board of Agriculture for 1894, as occurring at Bellaire. and the 

 writer has noticed it once in bulletin 160, as being injurious in 1897. At that time 

 it was at Traverse City on June 8. The beetle readily responds to a spray of paris 

 green whenever it becomes troublesome.
