 The larvse are fleshy, white and cyl- 

 indrical. They live in holes in the 

 ground^ and from the mouths of these 

 burrows capture other insects. They 

 are held in the holes by a forward pro- 

 jecting hook on the abdomen near the 

 posterior end. Tiger-beetle holes may 

 be found in great numbers in banks 

 or even in level ground. The adults 

 are also predaceous and capture other 

 insects. Tiger beetles have five-jointed 

 tarsi on all legs and thread-like antennae.

 also five-jointed tarsi and thread-like 

 antennas. They are, in a very general 

 way, flattened and have long legs, like 

 the tiger-beetles. No one acquainted 

 with the tiger-beetle form will mistake 

 them for ground-beetles and other fam- 

 ilies are easy to distinguish from these 

 two. Ground-beetles are generally black, 

 but some are bright colored, metallic 

 green and some shades of red and yel- 

 low being present in many species. 

 They range from small to very large. 

 As the name implies, they are found on 

 the ground, under logs, stones and 

 trash piles. They are attracted to lights
