The upper side of the head is flat, with a brown, triangular mask, in which the ocelli are placed. They are found in flowers. Many of their larvae mine the interior of vegetables, and some are very injurious to agriculturists, destroying various cereal plants previous to their fructification. The larvas of Muica Frit sometimes destroy the barley crops in Sweden, to the amount of 100,000 golden ducats in a year, being one-tenth of the produce. The larvae of Oscinit pumilionis and Uneata, Fab., are equally obnoxious. They constitute our genus Oscinis, Latr., to which we add the genus Chloropt, Meig., and Piopkila, Fallen. The fifth division (Dolichocera), which em- braces the genus Telanocera, Dum., is closely allied to the preceding, but the length of the second joint of the antennae, which equals or surpasses that of the third, at once distinguishes it. These organs are porrected, as long as, or longer than, Fi|{. ^^g j^g^^j^ ^^^ pointcd at the tip. The upper surface of the head forms a triangle, obtuse at the tip. Some have the antennae shorter than the head. Otites, has the seta simple, and the lower part of the face is not produced. Euthycera, Latr., has the seta plumose, and the lower part of the face produced into a truncated muzzle. The others have the antennae as long as, or longer than, the head. fiepedon, Latr., has the antennae evidently longer than the head, and the seta simple. Tetanocera, Dum., has the antennae as long as the head, and the seta sometimes plumose. The SLxth division, Leptofodites, is remarkable for the length and slenderness of the feet, the hind ones being at least as long again as the body, which is also slender and fiUform ; all t
