Land Scavenger Beetles.—These insects areterrestrial in their habits, and feed upon decaying or deadanimals, upon fungus, etc., and a few kinds are found beneaththe bark of dead trees. They may be divided into two Sub-tribes, as follows : * The larva (a) and pupa (c) are not those of the beetle figured at b; e is an egg case ; d, thesame cut open ; /, an antenna ; g, anterior foot of a female; h, same of a male ; i, side view ofthe spine on the breast. CLASSIFICATION OF INSECTS INTO FAMILIES. 85 Fig. 247. Sub-tribe I.—In these insects the body is rather broad, andthe antenna are clavate or capitate, with three or more piecesin the club. The principal Families are as follows: Burying Beetles (Silphidx).—These insects are mostly ofa large size, usually over half an inch in length; the hind tro-chanters are large, and the thorax has a thin margin. These Beetles feed upon dead animals, which, if not toolarge, they usually bury in the earth, to serve as food for theiryoung.
