The larvæ of several species have been described by Bouché (Naturgesch. derlns. 1834, 44, Tab. IV, Fig. 11—15) and Beling (Archiv fur Naturgesch. Jahrg. 41, 1875, 48—52, and Jahrg. 48, 188:2, 190-93.) They are elongated, nearly cylindrieal, of white or yellowish colour, with some brown fieids and spots on the dorsal surface of tho two firsl thoracic segments. The body consisls of twelve segments. The mouth parts consists of a median labrum, rather strong mandibles, which are hookformed, truncate at the ends and somewhat diverging, and maxillæ which are somewhat scaleformed and less chitinised, with two-jointed palpi. There are two-jointed antennæ, sitting on a spined piece. The abdominal segments have each a transverse, furrowed swelling on the ventral surface at the anterior margin. The last seg- ment terminates in four, conical, pointed warts. The larva is amphi- pneustic with small prothoracic spiracles and a pair of larger ones on the last segment between the warts. — The pupa has the antennal sheaths lying on the under side of the head, directed to each side; the sheaths of the wings and legs reach to the posterior margin of the second abdominal segment. There is a pair of small, round pro- thoracic and seven pairs of somewhat protruding abdominal spiracles. The abdominal segments have each, except the first, at the hind margin a girdle of sliort, strong spines, these being shortest on the ventral side; on the dorsal side there is a pair of stronger spines in the middle of the segments; the last segment terminates in six conical spines, four in a curved line above and two below. The larvæ live in the earth, they are carnivorous and devour other larvæ or penetrate into beetles which they devour; they also feed on earth-worms as stated by Marchal with regard to L. tringaria (Hull. de la Soc. Ent. de Fr. 11103
