If all controversial writings were as happy as Mr. Ashmead's last, readers of the Canadian Entomologist would not regret the space occupied, and I am glad that one side of the controversy in interesting reading. I hope I may be allowed space to say that Mr. Ashmead admits in conversation that he has erred in his statement that my first publication of the description of Rileya was in Canadian Entomologist for Oct., 1888, as I have shown him the last page of Entomologica Americana for July 1888.
