Economic entomology for the . economicentomolo00smit_0 Year: 1896 THE INSECT WORLD. 223 miJ'ichalcea, so named because of its resemblance to a drop of molten gold. The injury is done by these species just after the plants are set out and before they get a start. Where the season is unfavorable to rapid growth, some plants may be killed, but under ordinary conditions they are soon out of danger. Good practice is to set only large, weU-developed plants, or to dip everything before setting out in the arsenate of lead mixture recommended against the flea-beetles. Finally, it has been found that chickens are fond of the insects in all stages, and by turning loose a sufficient number in the fields after the plants have been set out practical exemption is secured. The bean- and pea-weevils constitute a little family by them- selves under the term BruchidcB. They agree with the leaf- beetles in general structure, but have a small head, prolonged into -^2- a blunt snout, a very obese abdo- men, exposed at the tip by the short, square wing-covers, and much enlarged hind legs, which are not used for leaping. They are always small and usually more or less ashen-gray in color, covered with whitish hair or scales, which Bean-weevil, Bruckus fabce much enlarged; 5, an infested bean. form variably evident markings on the wing-covers. The beetles are often found in dried seeds of leguminous plants,—peas, beans, lentils, or the like,—and are sometimics seriously injurious in the stored product, lessening also or destroying the germinating power. The beetles come out normally in the spring, and after pairing the females lay their eggs in the young pods of the plants affected by them. The larvae work their way into the forming seed and grow very slowly, the species varying somewhat in the details of their life history. Our only method of controUing the insects is in the stored product, or seed, and here by means of bisulphide of car- bon we can kill lan^ae as well as adul
