Fig. Closely associated with the insect I have just referred to is "the Lesser Apple-leaf Folder" [Teras minuta, Robs), which has also been very abundant this year, (Fig. 2), The caterpillars of this insect appear in early spring and commence their de- predations upon the tender foliage which has just come forth from the opening buds. They draw the opposite sides of the leaves together to form a habitation, and devour the foliage nearest to them. When they occur in large numbers they cause the trees to look as if they had been scorched by fire at the extremity of the branches. The moth is about a third of an inch long, with bright orange fore wings and silky white hind wings. There are two bi-oods in the year, the first moth appearing early in spring and the later ones towards the end of July. The larvie of another and larger moth, " the Oblique-banded Leaf-roller," (Cacossia rosaceana, Harris), have also been very numerous and destructive. This insect feeds upon a large variety of plants, both fruits and shrubs, but has been especially injurious to the apple during the past season. Like the two species already mentioned, it begins its attack in early spring by rolling up the young leaves of the plant and fastening them with silken threads. In the hollow cylinder thus formed the caterpillar (Fig. 3) takes up its abode, and when disturbed at one end quickly slips ?ut at the other and lets itself down and away from the threatening danger by means of a silken thread. There are a great many species of leaf-rollers known to entomologists—they belong to the family of Tortrices and are well repre- sented everywhere. Their habits are much the same in all cases, and when numerous they become a positive injury to the plants they attack. The moths may be at once recognized by their peculiar fiat shape, lesembling the outline of a bell when the wings are cl
