. Annual report of the Agricultural Experiment Station. Cornell University. Agricultural Experiment Station; Agriculture -- New York (State). A Plum Scale. 683 When the large shells are found, closely examine the bark in their vicinity for minute, verj^ flat, spindle-shaped, dark brown scales. Many of these are shown, natural size, on the plum branch in figure i ; when these young scales occur as numerously as shown in this figure, they are easily seen in the winter. It is this stage of the insect that now portends danger to some of the best orchards in the state. They are to be found snugly tucked away into almost every crevice on the trees from the trunk near the ground to the topmost twig How they got there, and what they will do in the spring (they are now doing no harm) is discus- sed further on under the life history of the pest. The male insect is also dis- cussed under the same neacling. Fig. i.—Plum branch containing many young scales in hibernation near the large mother-shells ; and phim leaves with many of the young scales along the veins, as they appear in sum,mer. All natural size, ITS NAME. This plum scale is allied to the well-known Mealy Bugs on green house plants, to the Oyster-shell Bark-louse so common on some unhealth}' apple trees here in the east, and to the very destructive San Jose Scale recently introduced into our state. However, the pest belongs to a different group of the scale known as the I^ecaniums ; several species of Lecaniums are serious pests in California orchards. As this difficult group has received compara-.
