 trees, and are exceedingly rapid in flight. 



CiCINDELA, Linn. 



The species of this genus are remarkable for the perfection and sym- 

 metry of their structure, the lightness and velocity of their motions, 

 both on the earth and in the air, and for the splendor and brilliancy of 

 their colors. They prefer arid and sandy places exposed to the sun ; 

 their flight is of short duration, rarely exceeding ten or a dozen yards 

 at a time; they are easily alarmed, and generally difiicult to capture.
