Economic entomology for the farmer Economic entomology for the economicentomolo00smit_0 Year: 1896 THE INSECT WORLD, 203 A beetle that sometimes does considerable injury to sugar-cane and corn in the Southern States is the ' sugar-cane beetle,' Li- gyrus rugiceps. Unfortu- nately, we do not yet know '^^^ its entire life history, and, as the injuries seem to have been rather local and occa- sional, it may be that it will not prove of wide or gen- eral importance. No satis- factory method of dealing with it is known at present. In the genera Xylo^yctes, Strategics, Dynastes, and Phileurus, we have a series of species more or less bizarre in form, with curious horns and processes on head or thorax or both, but not of economic interest, since neither beetles nor larvae are found on culti- vated plants. Ash furnishes food for several of the spe- cies in both larval and adult form. Beginning with the genus Aliorhina, we have a series of beetles that frequent flowers, feeding on pollen, but largely repaying what they devour by the benefit they confer in pollenizing. Sometimes, however, they prefer ripening fruits or even corn when in milk, and then become troublesome. Belonging to this genus Allorhina are velvety-green and dull-brown beetles, an inch or more in length, which fly during the day with a buzzing sound somewhat like a bumble-bee, and usually close to the sur- face of the ground, except where they attack fruit. Yet I have Ligyrus rugiceps.—The beetle and its work.
