The female lays her eggs(Fig. 138,1) in August under the scale protectingher body, and the young (2) hatch out in June,when they may be found running over the the middle or last of the month they becomeanchored by their long hair-like beak, and the S^ieinsect,day after, as Riley states, a white waxy secretionbegins to issue from the body, as seen in 3.

By the first of August thegrowth of the scale insect is completed, and it has theappearance of an oj^ster shell, as seen at 7. By the August in the western states, where Mr. Riley studiedits habits, the female lays her eggs, which do not hatch tillthe following June. It will be seen that the best methodof warding off the attacks of this pest is to thorouglilyscrape the bark of the tree in the early autumn and againin the beginning of June, when the 3oang are swarmingover tlie surface of the bark. At this time the bark shouldbe washed with whale oil soap. But it is to the naturalinsect parasite when reared and set loose in the orchardthat we are to look for the means of restraining withinproper limits this insect. This is the minu
