Nest of Tree Wasp, after sketch from original specimen by Eleanor A. Ormerod. 

 Dimensions eight inches across by seven and a half deep." 



The injuries to fruit and losses to fruit-growers and gar- 

 deners by Wasp depredations on the ripe or ripening props 

 are to a greater or less extent a yearly troul)le, but in no 

 season for many years has this been so great as in 1893, 

 when the visitation was so numerous and severe that it was 

 known as the " Wasp plague," and may be taken as an 

 example of the loss and mischief which a great Wasp infes- 

 tation can cause. 



* As the tenants of the nest were not identified at the time, I cannot s%f 

 with certainty whether it is that of Vesim sijlveatris or V.noricgica.
