Type. Cat. No. 20303, U. S. N. M. 



DIPRION SIMILE IN NORTH AMERICA. 



BY S. A. EOHWER, 

 Specialist in Forest Hymenoptera, Bureau of Entomology, Washington, D. C. 



In June, 1915, Dr. W. E. Britton recorded the European pine 

 sawfly, Diprion simile as occurring in nurseries at New Haven, 

 Connecticut. At this time the determination of this species 

 vvas tentative and the following note is presented to make this, 

 determination authentic. Since making this tentative determi- 

 nation for Dr. Britton we have received additional material 

 from European specialists and have carefully gone over all the 

 European species and studied them in detail, so do not believe 

 that there is any doubt that the insect occurring in our nurseries 

 is the European Diprion simile. 



In his annual report for 1916 Dr. Britton states that this species 

 is established in nurseries at five towns in Connecticut; and we 

 have received it in shipments from inspectors in Massachusetts, 

 Pennsylvania and New Jersey but have no record of its having 

 become established in any of these localities. We have, however, 

 received it from one nursery in New York under conditions 

 which indicate that it is established.
