This moth is a cosmopolitan, being injurious in Europe, and inhab-iting Japan and even Australia. It feeds on a variety of plants, not only devouring the calyx of the flowerbut the boll, and corn in the ear as wellas the stock, unripe and ripe tomates,green pease, string-beans, and youngpumpkins. It bores into the stalks ofthe gladiolus, and in Europe is known todevour the heads of hemp and leaves oftobacco and of lucern, as well as chickor coffee pea.—(Eilcy.)

It is usually deposited singly on the outside of theiu volucel or outer calyx of the flower or young boll, and each female mothis capable of thus consigning to their proper places upward of five hun-dred eggs.—(Kiley.) Some eggs of the boll-worm hatched in three or four days after beingbrought in from the field, the inclosed worms gnawing a hole throughthe shell of the egg, and then escaping. They soon commenced feedingupon the tender, fleshy substance of the calyx near the place where theegg had been deposited. When they had gained strength, some of theworms pierced through the calyx and others through the petalsof the closed flower-bud, or even penetrated into the young andtender boll itself. The pistils and stamens of the open flower arefrequently found to be disturbed and injured without
