Extract

452. Rachela Bruceata, Hulst.— Not observed previous to 1898. It appeared in millions in 1902, and in the following year was still more abundant. In those two years hundreds of acres of Populus tremuloides were completely denuded by the larv♀ during June. It appeared to be aided in its depredations by a Tortix, the name of which I have not yet discovered, but subsequent observation brings me to belive that by far the greater part of the denudation was caused by this species.
