like feelers, and their whole body ornamented with 

 the most splendid colours. They may be seen running 

 upon dry, sandy ground, particularly at noon on sunny, 

 warm days, but when one approaches them they fly 

 away so quickly that it is quite difficult to catch them ; 

 they however soon alight again. When taken be- 

 tween the fingers, they discharge from their mouth 

 a brown, fetid liquid, which has the odour of rancid 

 grease. Their strong, pointed, and crossing jaws 

 enable them to kill other insects with ease. 



Their grubs are soft and white, but are provided 

 with powerful jaws, and have the same rapacious 

 nature as their parents. They dig perpendicular 

 holes in the ground, and when driven by hunger 

 come up just so as to have their round heads cover 

 the entrance of their retreat, and here they wait until 

 some insect passes over the hole, when they seize 

 him in a moment, and drag him into their cavern. 



The Tiger-beetles, of which there exists many 

 species in the United States varying in colour and 

 size, destroy a great multitude of noxious insects, 

 and hence deserve to be respected and protected. 



The two species of Tiger-beetles represented in 

 the first Plato, Figs. 1 and 2, Cicindela repanda, and 

 C. sexguttata, were found near Cranston, R. L, upon 

 the sandy plains in the vicinity of the Stonington.
