HOP FLEA (Haltica condnna), a very smallcoleopterous insect, not quite one-tenth of an inchin length, which often does much mischief in hop-plantations in spring, devouring the tender tops ofthe young shoots. It is of the same genu5 with theturnip-flea (sometimes called turnip-fly), so destruc-tive to 1. nop Flea [Haltica concinna) : a, natural size; b, magnified; c, a fore-leg; d, a hind-leg. 2. Hop Fly [Aphis Ilumuli) : a, natural size; h, magnified. HOP FLY [Aphis Humuli), a species of Aphis() or plant-louse, important on account of theinjury which in some seasons it does to hop-planta-tiuus. It is, indeed, the principal cause of the gi-eat difference between the hop crop of one jear and ofanother, caiusing the variations in price and thespeculations for which the hop trade is notable.—The winged female is green, with a black head, andspots and bands of black on the body ; the legs arolong. A few winged females appear about the endof Slay, and wingless multitudes are sometimes tobe seen by the middle of June, on the under side ofthe hop-leaves and on the stems.
