The larva (Fig. 247, a) is about one-tenth of an inch long, of a pale pinkish-yellow color, glossy Fig. 247. and semi-transparent, with a dark line down the back on the two anterior and some of the posterior segments. On the terminal segment there are two short, fleshy horns united by a slight ridge; the horns are tipped with brownish black, and have a minute cluster of spines at their summit. The chrysalis, shown at h in the figure, is a little less than one-tenth of an inch in length, of a reddish-brown color, with a few short hairs scattered over its surface, and two blackish horns united by a ridge near the hinder extremity. Both the chrysalis and the larva are-magnified. The perfect insect escapes in about a fortnight after the chrysalis is formed. It is a very pretty little two-winged fly, shown much magnified at c in the figure, and of its natural size at d. The Phylloxera is also preyed on by the larva of a dull- colored lady-bird, a species of Scymnus, by several other species of the lady-bird family, and by the larvae of the lace- wino; flies referred to under JSTo.^T. To guard against its introduction Jnto new vineyards, the roots of young vines should be carefully examined before being planted, and if knots and lice are found upon them these latter may be destroyed by immersing the roots in hot soap- suds or tobacco-water. Our native American vines are found to withstand the attacks of this insect much better than do those of European.
