. Economic entomology for the farmer and the fruit grower, and for use as a text-book in agricultural schools and colleges; . A pomace fly and its larva, Drosophila species; enlarged. ing or decaying mass, and a few hours after- wards there will be an abundance of small, white, wriggling mag- gots. These become mature in three or four days, and after another day or two in the pupa state, they develop into adult "pomace flies," species of Drosophila. The insects are sometimes annoying and a little troublesome, but scarcely injurious, and it is only because they are so common and occur so suddenly in large numbers that they are mentioned here. Little attention is paid to the larvae either in wine or cider making, because they are thrown out in the process of fermentation, and do not in any way affect the quality of the resulting product. To this same family belong the " skippers" which are found in cheese and sometimes in other kinds of provisions. The term is derived from the habits of the larvae, which move about by a series of little jumps somewhat resembling those of the larvae
