 day found principally under stones and timber, at 

 the roots of grass, in the sand of gravel -pits, &c. ; 

 sometimes flies, but not to avoid pursuit. Ela-

 Brachinus, Dromius, Odocantha, Drypta. 



768. Tiger-beetles (Cicindelites}. Larva with 

 strong arcuate mandibles, and frequently with two
