Fernald, writing on the same, states that it has an extended distribution in the Orient, occurring in Japan, on the Island of Yezo and southward at least as far as Yokohama. It also occurs in China near Pekm, where it is very abundant, and it has been reported as far south as the Yiangtse-Kiang river, just north of the 30° of latitude.

It also occurs in China near Pekm, where it is very abundant, and it has been reported as far south as the Yiangtse-Kiang river, just north of the 30° of latitude. This distribution would indicate that the insect will probably be able to exist all over the United States except the peninsula of Florida, north of Mexico and in southern Canada. Its eastern food plants are Celtis, birch, elm and Japanese persimmon. It was found mostly in this country on Norway maples, pear, apple and cherry, though it also occurred on crab apple, willow, black birch, oak-leaved white birch, oak, American elm, Wahoo elm, black- berry, beech, poplar, mountain ash and buckthorn. This data is culled from a recently issued bulletin by Dr Fernald.^ The cocoon is an oval structure with peculiar broad white stripes [fig. i]. One specimen was found on a recent importation of Japa- nese maples in a greenhouse at Albany, though there is no evi- dence to show that the insect has become established in the open in Fig. I Cocoons of oriental slug caterpillar; this viciuity.
