These notes refer to a small but interesting collection of Hemiptera taken about Lake Temagami in August, 1906, by my friend, Mr. William J. Palmer, of Buffalo. Before starting for a brief vacation trip to northern Ontario, Mr. Palmer very kindly offered to collect Hemiptera for me as time and circumstances would permit. On four days only was he able to do any collecting, but considering the unfavourable conditions, the results were remarkably good, both as to the amount and character of the material brought home.
