Not illustrated. 1879 Excerpt: ...on the farmers of the West. In the year 1864, the losses occasioned by the chinch-bug in the corn and wheat crop of the valley of the Mississippi amounted to upward of $100,000,000. It is estimated that the average annual losses in the United States from insects is about $100,000,000. On the other hand, hosta of ichneumon flies and Tachina flies reduce the numbers and prevent undue increase in the numbers of injurious insecte. The number of species of insects is estimated to be about 190,000. Of these there are about 25,000 species of Hymenoptera (bees, wasps, etc.); about 25,000 species of Lepidoptera (butterflies and moths); about 24,000 Diptera (twowinged flies), and 90,000 Coleoptera (beetles); with about 4600 species of Arachnida (spiders, etc.), and 800 species of Myriopoda (millepedes, centipedes, etc.) Insects are distributed all over the surface of the earth. Most of the species are confined to the warmer portions of the globe, becoming fewer in the number of species as we approach the North Polar regions. Many are inhabitants of fresh water; a very few inhabit the sea. Insects, so far as the records go, first appeared in the Devonian rocks: these were Neuroptera and Orthoptera, such as May-flies aud other forms which seem generalized in structure. But if highly developed flying insects, belonging, at least the May-fly, to existing families, appeared in the Devonian period, it is reasonable to suppose that insects must have inhabited the dry land of the Silurian period. Insects are divided into four Bub-divisions or sub-classes--i.e., the Malacopoda, the Myriopoda, the Arachnida, and the six-footed, winged insects, or Hexapoda. All agree in breathing by air-tubes, and in having in most cases a triregional arrangement of the segments of the body. By...
