Extract

On August 22, 1933, while the members of the Montreal staff were inspecting a nursery in Montreal, P. Q., a small number of sawfly larvae was observed feeding on the mugho pine trees. These were submitted to Ottawa and were identified as the larvae of Diprion simile Htg. This was the second record of the appearance of this species in Canada; the first being a record from Oakville, Ont., in 1931. This insect had previously been studied in the Northeastern United States by Britton and Zappe (1917) and Middleton (1923).
