HOP-VINE SNOUT MOTH; RED SPIDER. 135 Prevention AND Eemedies.—Strong syringing, by means of tlie engines with some of the regular Hop-washes, or with the common hsh-oil soft-soap procurable at ten to twelve shillings per farkin of sixty pounds, appears to be one of the best remedies known. The soft-soap makes the Hop-bines unpleasant to the caterpillars, and, if applied as soon as any large number of the moths were seen about early in the season, would probably deter a large proportion from laving eggs on the syringed plants. Jarring the poles is also recommended, so as to make the caterpillars (which loose hold on a slight shake) fall to the ground; but the difficulty in this method of treatment is to keep them from going back again up the plants. Trampling on them throwing soot, lime, &c., or, in bad cases of attack, shaking them into something placed below or on to tarred boards, are recommended. Hand-picking the lea^ves with the moth-cocoons inside gets rid ot much of the second brood, and these cocoons are also to be lound about the stems of their various food-plants, on the surface of the ground, or in sheltered nooks. Clearing away plant-rubbish generally, and more especially the Nettle on which this caterpillar feeds, would be of service. Eed Spider. Tetranychus telarms, "Bed Spider," and hairs on the foot (from Claparede), magnified. (Nat size ordinarily invisible to the naked eye.) The "Eed Spider," which causes enormous damage in dry seasons to the Hop-crops, is neither an insect nor (properly speaking) a spider. Strictly speaking, it belongs to the Spinning Mites," * and the figure give
