. Economic entomology for the THE INSECT WORLD. 157 very strong mixture is necessary, and not more than six or seven parts of water can be added if a good effect is expected. In the case of the four-Hned bug already mentioned, the knowledge that it lays its eggs near the tips of currant and other twigs suggests a careful winter pruning, the cut twigs and branches to be burnt, and in this way injury may be prevented during the year following. This measure is successfully used where shrubby Fig. Pcecilocapsus lineatiis, four-lined plant-bug, natural size and enlarged : also egg mass in currant, and, at e, a single egg, greatly enlarged. or woody plants are attacked ; but on succulent annuals, collect- ing the insects in the morning, before they have become active, by shaking them into some sort of receptacle, is the most satis- factory method. In the Cotton belt there was no more troublesome insect, some years ago, than the red-bug," or cotton-stainer," Dysderciis suturelhis, so named from the fact that its excrement, voided in the opening bolls, stained the cotton red, and thus caused it to become of inferior value. Since cotton-seed has become almost as valuable as the cotton itself, and is now completely used up, it has been found that these insects have become practically harm- less. It seems that they were enabled to multiply unduly in the heaps of decaying cotton-seed, and since at present no such heaps exist they cannot increase so rapidly. They also attack oranges in Florida, and Professor Comstock recommends that they be.
