OBSERVATIONS. 



This is by far the most beautiful species of 

 the genus, yet discovered. When the rays of 

 light fall perpendicularly on the surface of the 

 elytra, a highly brilliant reddish-coppery colour 

 is exhibited, but when the rays are reflected at a 

 considerable angle, the tint changes to a fine po- 

 lished green. The specimen was brought from 

 the Missouri, by Mr. Thomas Nuttall.
