One of these flies {Aleiodes lideyi, Cresson) is of a uniform red- dish yellow colour. The other is a black fly of about the same size, but belonging to an entirely different genus, ; The only artificial remedy which has been recommended is that of hand-picking. 10. The Stawberry Falseworm, {Emphytus maculatus, Norton). This insect, although it has not j'et been observed in Canada, will very probably be with us before long. It has been common in the adjoining Western States for some time past, and as the perfect insect is winged, and during the hotter portion of the day quite active, and since the strawberry now is so widely cultivated, there is nothing to hinder the spread of this destructive insect, the habits of which it will be well for us to fully under- stand, so that we may know how to treat the enemy on its first Tippearance. We know that a near relative of this insect, the gooseberry saw-fly {Ncmalus ventrkosus) has spread in a short time over a large section of our Province. Since we have had no personal ex- perience with this foe to the strawberry grower, we shall avail ourselves of an excellent description of its life, history and habits, written by Mr. C. Y. Riley, of St. Louis, Mo., and pdblished in the first volume of the " American Entomologist," p. 90. The adjoining Figure 14, draw
