. Agricultural zoology. Zoology. INSECTS. 165 condition in cellars, barns, etc. The female lays to 300 eggs on any floating object in stagnant water (pools, ditches, water-vessels). The larvae (with large head, well-developed prothorax, and a breathing-tube on the abdomen) live in water, as do the pupae. Several generations annually; especially in damp summers and districts where the draining of the soil leaves much to be desired. Although sand-flies torment our domestic animals more than gnats, yet these also may be very troublesome to them. They principally attack the less hairy parts of the body (inner side of the ears, nose, mouth, corners of the eye, arms, sexual parts). Meviedies: Thorough drain- ing of the soil. Washing the domestic animals to be protected with a vinegar extract of walnut leaves; rubbing with walnut-leaves. Wherever possible, any sores should be covered up, as they attract gnats, sand-flies, and flies ; or the skin near them may be painted with turpentine or very dilute carbolic acid. This is the less to be neglected, as several kinds of flies eagerly lay their eggs in the sores of domestic animals. Family : Gallieolae (Gall Gnats). Small gnats with large broad wings, much narrowed at the root, rounded at the tip, and gene- rally rough with hairs. Feelers made up of a large number of spherical or cylindri- cal joints, covered with spreading hairs. Proboscis short, legs long. The female has an ovipositor, with which she inserts eggs in any part of a plant. .. ,!• i- 1 J.
