This insect belongs to a family closely related to the Aphides,differing in the veining of the wings, and in having antenmeknobbed at the end. They jump as readily as a flea. The fol-lowing account of their injury was given by Charles Parry, ofCinnaminson, New Jersey, in 1869: The suckers upon which this insect occurs in the springcommence to twirl around, and, when not interfered with, make THU BRAMBLE FLEA-LOUSE 255 a complete revolution before they resume their usual leaves curl up, and become matted around the curl, so as tomake a safe harbor for the lice-like larvaB, which during thesummer appear on the under surface of the leaves. I presume. Mistletoe of the blackberry. we can get clear of this insect, after the larvae are producedby cutting off the curls and burning them. In 1880 A. S. Fuller calls attention to the rapid increase ofthis insect, and to the great injury to blackberry plantationscaused by it. It is also mentioned by W. C. Strong, in his workon fruit culture, as doing great damage in some localities. The 256 BUSH-FRUITS injuiy caused by it has been mistaken for a fungous disease attimes, and in parts of Delaware it is known as Mistletoe.(See Fig. 33, from Bull. 117, Cornell Exp. Sta.) Remedies.—Thorough work in cutting out and destroying theinfested tips, taking care that none of the insects escape, woulddoubtless prove effectual. Mr. Strong recommends strong to-bacco water. Kerosene emulsion may prove to be the mostefficient and practicable remedy. The Bud Moth Tmetocera o
