REPORT OF TI-IE CURATOR. 



The collections of the Society have been examined from time to time during 

 the past year and kept free from museum pests. 



With a view to supplying in a small way the sa:d need of Diptera, Hemiptera 

 and Hymenoptera, special collections were made this summer and, as soon as the 

 material can be identified and labelled, it will be added to the collections. 



Contributions of thc^se orders to the Society collections from members will be 

 greatly appreciated. 



G. Spencer, Curator.

 young locusts began to appear towards the end of May, but owing to dull, cool 

 weather conditions did not become active until the first and second weeks of June. 

 The Lesser Migratory Locust {2lelanoplus aUanis) was the chief destructive 

 species. It was accompanied in noticeable numbers by the Pellucid Locust 

 {Camnula pellucida). These two species are frequently found Avorking together. 

 Near Bowesville, Ont., where we continued our work on control with poisoned 

 baits, the insects were present in countless thousands. The crops attacked were 

 chiefly oats, barley, timothy, buckwheat, clover, tobacco, potatoes, and corn. In
