Family CARABID^. 



The "ground beetles," as the members of this family are popularly 

 known, are usually black or dull brown in color, sometimes bronzed or 

 metallic, and, exceptionally, usually on flower-loving forms bright blue, 

 green and yellow. Many of the species hide during the day under stones 

 or bark, among roots of plants, in grass at the base of trees, in burrows 

 under ground or in other places of concealment. They fly at night, are 

 often attracted to electric light, and in general are predatory in habit. 



The larvse are more or less fusiform, somewhat flattened above, gray 

 or dusky in color, and they live in similar localities though even more 



concealed. They also are 

 predatory and of decided 

 r - economic importance, feed- 

 ing upon many of the leaf- 

 feeders that go under- 

 ground to hibernate or to

feed on eggs, caterpillars and slugs of herbivorous forms. 



All the species have slender, filiform antennae, 5-jointed tarsi on all 

 feet and are somewhat depressed or flattened; those that live under bark 

 sometimes very much so.
