3 importation of rose bushes rrom eastern nurseries to western gardens. Owing to the sluggish habits of the female, its distribution by flight i has undoubtedly been very slow. Its occurrence in New York, New Jersey, Ohio, Illinois, Michigan, and Missouri has been known for a 1 number of years, and it undoubtedly occupies intervening States. In 1904 we received reports of injuries by it in Pennsylvania, New York, Maryland, and Kansas; in that year it also appeared at Char- lottesville, Va., and the following May reached the District of Colum- bia, where it has been quite abundant since. In 1908 it was reported injurious at Cincinnati, Ohio.

(Original.) LIFE HISTORY. The parent saAvflies issue from the earth at varying times from about the 1st of April, or earlier in the District of Columbia, to the third week in May, or, according to Harris, until the middle of June in Massachusetts, beginning at about the time when the roses first unfold their leaves and continuing until they are in full leaf. During this period pairing takes place and eggs are deposited. The females are particularly sluggish in the cool of morning and are not often seen in flight, resting during the greater part of the day on the leaves. When disturbed they draw up their legs and fall to the ground. The males, however, are quite lively, flying from one rose bush to another and hovering around their less active partners. (Cir. 105)
