When observed on a tree they are usually in immense numbers, thickly clustered together and often overlapping each other. In shape and markings they bear some resemblance to a turtle and have therefore received the name of "the Terrapin ; The specimens that we have seen were sent in from St. Catharines, Windsor and Walker- ville, and in each case were found on Maple trees. Many of them were perforated, showing that they had been destroyed by a minute parasitic insect. This scale is widely prevalent in the Northern and Eastern States, but is not common yet in Ontario. It attacks a large number of wild and cultivated trees and shrubs, and is especially injurious to peach trees. As it will readily spread from one tree to another, it is important that any wild trees found to be infested should be cut down and burnt at once. The only remedy for the insect when it attacks fruit trees is to spray with kerosene emulsion in the fall and winter or in early spring before the leaves come out.

Next to the San Jose Scale, it takes rank as the worst enemy that the peach-grower has, and prior to the arrival of the scale destroyed more trees than all other causes combined. The parent moths are very pretty creatures; the male has a steel-blue body with golden-yellow markings and clear transparent wings which expand about an inch ; the female is considerably larger and totally different, the body being more than twice as thick, of a similar glossy steel-blue color but crossed with a brilliant band of orange; the fore wings, which expand an inch and
