Flea-beetles (Halticini).— Small, dark-colored jumping beetles that riddle the leaves with holes. See p. 303.

Preventive. — Bordeaux mixture as applied for potato blight acts as a repellent. Potato Tuber-worm (Phthorimaea operculella). — A small caterpillar burrowing in the stems and tubers both in the field and in storage. Preventives. — Clean cultivation, sheep and hogs to destroy the small potatoes left in the field after digging. Crop rotation over a considerable area. On digging remove the potatoes at once to an uninfested storeroom. Do not leave them on the field over-night. Wire-worms. — See p. 305. Privet or Prim. Privet Web-worm (Diaphania quadristigmalis). — Small larva feeding in webs on the young shoots of the privet, appearing early in the season ; two to four broods.

Remedies. — Trim the hedge as soon as the worms appear, and burn the trimmings. Probably the arsenicals will prove useful. Quince. Gound-headed Borers. — See under Apple, p. 308. Slug. — See under Cherry, p. 313.

Quince-curculio (Conotrachelus crataegi). — This curculio is somewhat larger than that infesting the plum, and differs in its life-history. The grubs leave the fruits in the fall, and enter the ground, where they hibernate and transform to adults the next May, June, or July, depending on the season. When the adults appear, jar them from the tree on to sheets or curculio-catchers and destroy them. To determine when they appear, jar a few trees daily, beginning the latter part of May. Arsenicals. Radish. Maggot (Pegomya brassicae). — Treated the same as the

Cabbage-maggot, which see (p. 312). Raspberry. Cane-borer (Oberea bimaculata). — Beetle, black, small, and slim ; making two girdles about an inch apart near the tip of the cane, in June, and laying an egg just above the lower girdle ; the larva, attaining the length of nearly an inch, bores down the cane. Also in blackberry.

Remedy. — As soon as the tip of the cane wilts, cut it off at the lower girdle and burn it. Raspberry Root-borer {Bembecia marginata). — Larva about one inch long, boring in the roots and the lower parts of the cane, remaining in the root over winter. Remedy. — Dig out the borers. Raspberry Saw-fly {Morwphadnus rubi). — Larva about three-fourths inch long, green, feeding upon the leaves. Remedies. — Hellebore. Arsenicals, after fruiting. Root Gall-fly (Rhodites radicum).—A small larva which produces galls on the roots of the raspberry, blackberry, and rose, causing the bush to appear sickly, and eventually killing it. The swellings are probably often confounded with the nematode root-galls, for which see p. 303.

Remedy. — There is no remedy except to destroy the galls ; if plants are badly affected, they must be dug up and burned. Snowy or Tree-cricket ((Ecanthus niveus).— Small and whitish cricket-like insect, puncturing canes for two or three inches, and depositing eggs in the punctures.

Remedy. — Burn infested canes in winter or very early spring. Rhubarb. Rhubarb-curculio (Lixus concavus). — A grub three-fourths inch long, boring into the crown and roots. It also attacks wild docks.

Remedy. — Burn all infested plants, and keep down the docks. Hand-picking. Rose. Root Gall-fly. — See under Raspberry, above.

Mealy-bug. — Tobacco extracts. Syringe the plants in the morning, and two hours later syringe again with clean water. See also p. 303. Rose-chafer, Rose-beetle, or " Rose-bug." See Grape, p. 322. Rose Leaf-hopper (Typhlocyba rosae). — A very small hopper, white, often mistaken for thrips, living on the leaves of roses.

Remedies. — Whale-oil soap. Kerosene. Kerosene emulsion. Dry pyrethrum blown on bushes when leaves are wet. Tobacco extracts.
