The back is arched, and not capable of being extended in a straight line ; so that these grubs, of which that of the common cockchafer affords a ^ood ex- ample, walk bat badly on a smooth surface, tumbling over at every step. Some species do not change to pupae until they have passed three or four years as larvae. They form for themselves a sort of oval casing, in their retreats, with earth or the debris of the materials they have gnawed, of which the particles are united together by a glutinous secretion. Their food consists of dung, manure, tan, and particularly (in some species) of the roots of vegetables ; whence these insects, especially in their larva state, often occasion great loss to the cultivator. This family receives its name from the peculiar conformation of the antennae, which terminate in a mass formed of the three last joints ; these are flattened into plates or lamella ; and somtimes arranged like a fan or the leaves of a book, sometimes in the manner of a comb, and sometimes enclosing each other. The family is distributed into two principal sections, the Scarabdei and the Lucani. 520. Of the Scarabdei, one subdivision, including the sacred beetle of the Egyptians, feed principally upon the excrements of various animals ; and they enclose their eggs in balls of the same (whence they have been called Pilularii), which they roll along with their hind feet (several often being in com- pany), until they reach the hole in which they are to be deposited. To this group also belongs the geotrnpes slercorarius, the com- mon dor or shardborne beetle, which is one of the commonest British insects. A most remark- ably-formed species is the dyiias-. Aieuehus (Scarabaeus) ^Egyptiorum. 5(i2. How is the sixth family characterized ? 563. What of their various habits? 564. Name the varieties of this Please note that these images are extracted from s
