I have just received from Mr. James Fletcher a small bottle of scales found on plum at Queenston, Ontario. He writes concerning them: “Dead scales picked from a plum tree in the Niagara district, where it was very abundant on plums and much rarer on peach trees growing amongst the plums”

Directiy I saw these scales, they struck me as something unusual, and yet I rather expected they would prove to be some form of L. persicœ. Unfortunately they were full of the mycelium of a fungus (doubtless Cordyceps), as well as in some cases containing a Chalcidid parasite, so that their specific characters were very hard to make out. The fungus, which must be a very important check to their increase, was not noticed on examination with a lens; but on boiling the sacles in liquor potassæ, they stained the liquor brown, and a microscopic examination showed the fungus quite plainly. Of course, from mere mycelium no determination could be made. I saw in one case what looked like germinating spores, but perhaps in this I was mistaken.
