AQUATIC INSECTS OF FRESHWATER ing patterns and shades in brown. It may be seen on the wing in early summer, deposits its eggs, encased in a gelatinous capsule, on the under side of floating leaves near the edges. The larvae burrow into the leaf until too large to find a refuge, when they bite off oval pieces and fasten them to other parts of the leaf with a gelatinous secretion or silk; and in this secure retreat the molts take place. The more general species are H. obliterans, Fig. 232, which lives on water plants in greenhouses, rarely out-of-doors, H. albalis, H. allionealis, A. ekthlipsis, H. icciusalis, H. obscuralis, H. stenialis, and six other species on the Atlantic slope of the United States. China-Marks or Cataclysta are small moths, rarely over ^ inch spread of wings, of which those of the male are white, with bkck mark- ings and of the female brownish with darker markings. The larva is brownish and is most often found among the duckweed, of which it spins together the leaves to form a casing. The more general species are C. fulicalis. Fig. 232, and C. bifascialis, with three other species not so generally distributed in the United States. There are several other genera of Lepidoptera which are semi-aquatic but which are not generally distributed and need not be mentioned here. Order Arichnid^. This order, consisting of the spiders, scorpions mites and harvest-men, possesses certain characteristics in common with the Crustaceans with which it is allied. All the families have a com- bined head and thorax, a globular, ovate, cylindrical or triangular abdomen connected by a slender waist; eight legs attached to the thorax, and simple eyes, varying from 2 to 12 in number, placed in two trans- verse rows. The mouth parts are armed with powerful forceps to seize, hold and poison their prey, be
