Economic entomology for the farmer and fruit-grower : and for use as a text-book in agricultural schools and colleges . THE INSECT WORLD. 171 The family Silphidcs, containing what are popularly known ascarrion and burying beetles, is in sharp contrast to any-thing heretofore spoken of, and here the antennae are capitate,—, terminated by a spherical or ovate knob abruptly formed,like a head. The beetles are usually found on or about carrionof all kinds, though some of the smaller forms live in decayingfungi. In the large species there are two distinct types, repre-sented on the one hand by the genus Siipha, in which the species FiG. Carrion beetles.—a, Necrophorus amcricana ; b, larva of Siipha lapponica ; c, Siipha americana. are much flattened and proportionately very broad, with smallheads, and on the other by the genus Necrophorus, in which thespecies are much more heavily built, narrower, not flattened, andwith large heads. These are the true burying beetles, andderive the name from their habit of excavating beneath smalldead animals and gradually sinking them below the surface the females lay their eggs in and the larvEe live upon theburied and decaying creatures. The other carrion beetles makeno pretence of burying their prey, but lay their eggs at once,and the larvae feed upon it from below, usually making a shortburrow in the soil for shelter, though this is not universal. Inboth types the larvae are black, flattened, broadly oval, and with
