Distribution. 



Our attention was called to this , insect in 1906, -and Barnes 

 Brothers observed its work in 1905. Since then we have 

 received no complaint from other orchardists of injury that 

 could specifically be laid to this pest. Observations regarding 

 the distribution of the peach sawfly have been made as follows, 

 the larger orchards having been visited especially to look for 

 the insect or its work: 



Places Where the Insect has been Found. 



New Haven, June, in three city gardens and in garden of 

 Experiment Station. 



Meriden, July 9th, small peach orchard of E. M. Ives; occa- 

 sional leaves had been eaten, and a few full-grown larvae were 

 found. 



Centerville, July 12th, orchard of George C. Neal. A number 

 of larvae. The pest evidently well established. 



North Haven, July 12th. The insect was present upon a few 

 peach trees in a henyard.
