 ( Continued from page 315.) 

 Eulecanium Fitchi, Sign. This seems to be a very serious pest. 

 The specimens sent by Dr. Fletcher came from Mr. J. I). Evans, of 

 Trenton, Ont., and the scales were infesting a plot of six acres of black- 

 berry bushes, just as they were about ready for the market. Fortunately, 

 however, of the first lot received, over one half of the scales were de- 

 stroyed by a fungus, and of the second lot, about one third at least. 

 Trenton is a new locality for this scale. In addition, the scale insects 

 were infested to a remarkable extent by two species of Hyperaspis and 

 two species of Chalcid parasites.

 in Nova Scotia. Coll., Prof. Mackay. This is a new locality.

 elm at Arnstein, Ont., which is a new locality.

 willow growing at London, Ont. Coll., J, Dearness. 



Aspidiotus ancylus, Putn. This was sent by Mr. Dearness, on plum 

 arid shell-bark hickory from East Essex Co., Ont.

 palustris) growing near the shore of Lake Huron, in mixed woods, about 

 40 miles from London, Ont., May, 1899. Coll., Mr. Dearness. The
