Entomological Society of Ontario; Insect pests; Insects. 43 of their vital principle by this dreadful enemy. * * * It is far more destructive to fruit trees than any other insect, infinitely more so than the canker-worm, but unlike the other depredators of our orchard trees, it is easily kept in check, and at small expense permanently ; Figure 5 (after Riley), represents both the larva and perfect state of this insect. The moths appear during July and August, and expand about an inch and a half. Mr. Harris describes messoria as follows:— "The fore wings are reddish gray, crossed by five wavy blackish bands, the first two of which, and generally the fourth also, are double; the Fig. 5. two ordinary spots, and a third oval spot near the middle of the wing, are bordered with black. The hind wings are whitish, becoming dusky brown behind, and .have a small central crescent and the veins dusky. The head and thorax are chinchilla-grey; the collar is edged with black; and the abodomen is light ; Agrotis scaxdexs.—Riley. The Climbing Rustic Moth—Larva—Tlie Climbing Cut-worm.—Riley. This moth, described by Mr. Riley in his First Report, is also on the list of the Entomological Society of Ontario. It is very common in the Western States, and the larva is very injurious to apple and other fruit trees, devouring the blossom and leaf buds in early spring, in the same manner as the species last described. Even though it may not be common in Ontario, a knowledge of its habits is necessary, as our fruit-growers are often not aware of the reason why so many of their trees dwindle away and at last perish; and in many cases the loss may be caused by the attacks of this cut-worm, or others of similar habits. The full-grown worm is nearly an inch and a half in length, and of a very light yel- lowish grey colour, variegated with dirty bluish green spots, and when filled with food it has
