The aquatic genera are all harmless to young fishes and constitute a part of their natural food. Order Coleoptera. Of this order a number of families are aquatic. They have a pair of veinless horny wing covers or elytra, occupying the position ofthe fore wings, folded and meeting in a straight line down the back, under which is a single pair of membranous wings, though some species have the rudiments of fore wings under the elytra. More than 80 families ot Coleoptera occur in America north of Mexico and over 11,000 species have been described. The most generally distributed genera and species of the Eastern section of the United States, which for either a part of, or their entire existence, inhabit the water,are the Predaceous Diving-beetles or Dytiscids; the Water-scavenger beetles and Great Water-beetles or Hydrophilidae, the Whirligig-beetles or Gyrinidse; the Pond-beetles or Haliplidse; and many other smaller beetles belonging to these genera. Predaceous Diving-Beetles or Water-Divers belong to the family of Dyti
