This arrangement is by no means perfect,for there are beetles which are car-nivorous in the larva and herbivor-ous in the imago state; while some ofthe NECROPHAGA are actually para-sitic. Yet, it is not more artificial than others which have been carnivorous species, broadly speaking, are Pentamerom, the onlystriking exception being the Coccinellidae (Lady-birds), which arePseudo-trimerous. The carrion-feeders are also Pcntamerous; but veg-. FIG. 12.—A Soldier-beetle, Chaulioynathuspennsylvanicus. a, larva; b-h, parts oflarva enlarged; i, beetle.
