The sub-family Languriides ((juite wanting in Europe) consists of more elongate Insects, with front acetabula open behind ; tliey have different habits from Eroty- lides proper; some are known to live as larvae in the stems of herliaceous plants. They possess a highly developed stridulating organ on the front of the head. The Clavicorn Polymorpha are very closely connected with the Phytophaga by Languriides. Fam. 37. Mycetophagidae.—Torsi four-jointed, slender, the front feet of tlie male only three-jointed; coxeie oval, not deejily embedded; abdomen ivith five ventrcd seg- ments, all movable. A small family, of in- terest chiefly because of the anomaly in the feet of the two sexes, for which it is ini- piossiljle to assign any reason. The species are small, uninteresting Insects that live chiefly on Cryptogams of various kinds, especially in connection with timber ; the larvae being also found there. There are ab(jut a dozen species in Britain, and scarcely 100 are described from all the world. The Diphyllides, placed by Leconte and Horn in tliis family, seem to go better in Cryptophagidae. Fam. 38. Coccinellidae {Lady-birds).—Tarsi apj^ccrently three- jointed; the first two joints j^ubeseent beneath; the third joint consisting recdly of tivo joints, the smcdl true third joint being inserted near the base of the second joint, the upijcr surface of which is grooved to receive it. Head much concealed by the thorax. Antenncte feebly clubbed. The lady-birds number fully 2000 species. The structure of their feet distinguishes them from nearly all other Coleoptera except Endomychidae, which are much less rotund in form, and have larger antennae. One genus of Endomych
