The branch is evi-dently poisoned by their operations, and frequently dies down to the wood of the previousgrowth. If the tree is abandoned to the insect, the young wood is soon all killed. The other insect to be noticed resembles the squash bug, and is called by the entomolo-gist of the Department of Agriculture, Euthoctha gakalor. These insects are very bold in theirattacks. I have watched them frequently in their operations as they were lying in the hotBun basking, while their probosces were inserted in the tender shoots. I have held my mag-. THE SHARPLESS SEEDLING.

As this insect is larger than the spider, theinjury inflicted by it is much more speedy. But when the shoot is older and more vigorous,the effect is very similar to that produced by the spider. As no natural enemies to either of these insects are known, watchfulness on the part ofthe orange grower is alone to be relied upon for their destruction. They should be caughtby hand, or in a net, and killed. The insect last described is very apt to conceal itself underlitter during the winter. Pieces
