As in the Dyticus, there is a remarkable enlargementin the fore tarsus of the male Hydrophilus, the last jointforming a large triangular plate, furnished with second pair of legs is also spinous, as in theDyticus the tarsi of the second pair correspond withthose of the first in being furnished with suckers. * It is supposed to arise from the voluntary emission of a volatile same thing occurs in many other beetles, as in the Carabus, the Bom-bardier, and 72 INSECTS. The larva of this beetle is one of the fiercest huntersof the water. The Hydrophilus has a habit, singular among beetles,of spinning a flexible silken sac, in which to enclosep.^ g^ her eggs (fig. 34). This is described as resembling a turnip upside down ; acurved, pointed horn, about one inchlong, rising from the upper side of thesac, which, being compressed on twosides, measures about three-quarters ofan inch at its widest, and half an inch atits narrowest of egs of Hy- There are several other families ofdrous piceus. non-predaceous beetles both aquatic andsemi-aquatic. Some live in the moss and grass by theside of pools and streams, at times freely entering thewater and running on the bottom.
