Economic entomology for the farmer Economic entomology for the farmer and the fruit grower, and for use as a text-book in agricultural schools and colleges; economicentomol00smit Year: 1906 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- •rynis rugiccps. Unfortu- nately, we do not yet know- its entire life history, aiul, as the'injuries seem to have been rather local and occa- sional, it may b^ 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 Xyloyctcs, Strategus, Dynastcs, and Philcuriis, 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 Allorhina^ we have a series of beetles that frequent flowers, feeding on pollen, but largely repaying what they devour by the benefit they confer in poUenizing. 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 \.U\GUO\-S. Ligvvus rugict'ps.—The beetle and its work.
