We have only six species in Britain, and tiie wliole of Europe has only about two dozen, most of them insignificant (and in the case of the Dacnides aberrant, approaching the Cryptophagidae very closely). The sub-family Languriides (quite 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 lierbaceous plants. They possess a highly developed stridulating organ on the front of the head. The Clavicorn Polymorpha are very closely connected w-ith the Phytophaga by Languriides. Fam. 37. Mycetophagidae.—^Vw-si four-jointed, slender, the front feet of the mcde only three-jointed; coxae ovcd, not deeply enbcdcled; abdomen with five 'centred seg- ments, cdl movable. A small family, of in- terest chiefly because of the anomaly in the feet of the two sexes, for which it is im- possible 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 about a dozen species in Britain, and scarcely 100 are described from all the world. The Diphyllides, placed by Leconte and Horn in this family, seem to go better in Cryptophagidae. Fam. 38. Coccinellidae (Lady-birds).—Tarsi cqjj^arently three- jointed ; the first ttvo joints ifubeseent beneath; the third joint consisting recdly of two joints, the smcdl true third joint being inserted near the base of the second joint, the upper surface of which is grooved to receive it. Head much concecded by the thorax. Antennae 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 ha\'e larger antennae. One genus of Endomychids—Fano
