L. this vast nmnber can be included mthin a relatively small number of families, of which the salient general characteristics will here be considered. The running beetles are characterized by a more or less slender body, long, delicate legs, and quick movements. They are found chiefly on or near the ground. There are t^vo principal famihes. The first includes the tiger-beetles (Cic"inderid£e'), which are colored bright brown or green (Fig. 66). They are light-lovers, heat and moisture lovers. Conseciuently they are found in sunny places, especially on paths or sandy shores which reflect the sun's rays, and almost always in the vicinity of water. In their flight they are among the swiftest of insects; ^ Derived from caudela, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Davenport, Charles Benedict, 1866-1944; Davenport, Gertrude Anna Crotty, 1866- joint author.
