Gardening; Fruit-culture; Vegetable gardening. Fig. 16. Parasite of the Soft Brown Scale {Encyrtus flavus Howard [Family Bncyrti- dae]). A small parasite scarcely one-six- teenth of an inch long-. The general color of the female is ochre; compound eyes brown; ocelli red; antennae yellow with tips black; the tips of the feet black. The basal third of the fore wings are clear with the remainder clouded with brown; the hind wings are clear. The males are consider- ably smaller than the females, and shiny metallic green in color with legs and anten- nae very light; wings clear with brown veins. Quite common throughout California, but especially abundant in the southern part. The soft brown scale (Coccus hesperidum) is often very effectually checked by its attacks. The beetles are now in their final pack- ages ready for distribution. But the time when they are needed will not ar- rive for six months, and meanwhile they must be kept alive and in first class condi- tion. This, indeed, is the most difacult part of the whole business, the great problem being, as will be understood, to extend by artificial means, the natural hibernating period of the beetles in such a way that they may not lose any of their vitality. In order that this may be accomplished they must be kept cold, without exposure to any marked change in temperature. If they are allowed to become warm, even for a little while, or moisture comes in contact with them, they will heat and cake into a solid mass, thus killing the entire colony in a remarkably short time. A temperature slightly under 40 de- grees Fahrenheit and plenty of ventilation is an absolute necessity, and the air must also be slightly moist, and the "crop" requires continual attention and at times the conditions must be changed quic
