This is an insect varying in color from light yellow to dark brown, and much more active in its movements than the Green-Fly, and more difficult to destroy; when it once gets a foothold it is very destructive. It succumbs to tobacco, in any of the forms recommended for the destruction of Green-Fly, but not so readily. It luxuriates in shaded situations, and generally abounds where plants are standing too thickly together, or where ventilation or light is deficient. It may be safely asserted that in any well regulated place where plants are kept, no injury from insects will ever become serious if due attention has been given to keeping the atmosphere of the place moist, and using tobacco freely in any of the forms we have recommended.
