Vermillion County; rare. July 21. Dury has taken this hand- 

 some beetle in numbers near Cincinnati on the spiderwort, Trades- 

 cantia virginiaiia L. He states that it is the most active Chryso- 

 melid known to him, flying like a Cieindela 50 to 100 feet before 

 alighting, and that it occurs only in late June and July, the males 

 disappearing by July 15th. It probably occurs throughout the 

 southern third of Indiana.
