The larvae of the Clerics; are elongate,usually of a reddish, reddish-brown orpinkish colour, or somewhat variegated, withrather thick pubescence. The larvse of Trichodes were called red-worms by Swammerdam, who first described their habits ; theyare furnished above with chitinous plates on the thoracic segments,and the last segment is chitinous and bears at its apex twoprojecting points, and a short anal appendage ; there are five ocellion each side of the head. These krvse are parasitic and derour. Fig. 61.

The} are thereforedecidedly useful insects. Certain of the are very like bees (this is especially thecase with Trkliodes), while others bear a strong resemblance tolarge ants; these resemblances are probably very useful in theeconomy of the insect. The species of Necrobia and its allies are in many cases foundin old bones, hides, etc., and have been widely spread by commerceuntil they are now cosmopolitan. The following are the chiefdivisions of the family as given by Lacordaire, and in substance byLeconte and Horn, and recently by Schenkling(Wytsmans GeneraInsectorum I.
