Birds observed at Montreal. 417 
Of three summer warblers obtained on the same date, the 
stomach of one contained specimens of Syneta triplax, a leaf- 
eating beetle, and although not sufficiently numerous to do 
much harm, is certainly to be classed as injurious. The 
second had been eating a species of Paria, also injurious. 
The third contained some triplax, same as first, also some 
of a species of Aphodius, a beetle living in cattle droppings, 
and may be set down as neutral.
