 name for the common P. armoricce of Europe. From its activity 

 in New Jersey, it can easily do considerable damage, feeding as 

 it does, in both larval and adult stages, but, of course, can undoubt-

 sent me word that the bat-fleas of which I gave an account in the

In connection with an investigation of the introduction of 

 the San Jose Scale into Ontario, I called on the 16th day of August, 

 1899, upon a farmer who, the neighbours said, was the first man

 Niagara River. A grove across his property cut ofT the view of 

 the lake. In conversation, he mentioned the fact that this grove 

 was then swarming with red butterflies. I went back through it 

 and found that he had not exaggerated, for, verily, there was a 

 multitude of "monarchs" there "that no man could number."
