OBSERVATIONS. 



A handsome species, easily distinguished from 

 others by the rugous thoracic line, combined 

 with the O O at the base of the elytra. It 

 inhabits this state, and Mr. T. Nuttall presented 

 me with many specimens which he found in 

 Arkansaw. The bands of the elytra are some- 

 times white.
