Collected at UV light in deciduous woods. The elytral margins are coppery red but this did not come out in the picture. I do not know of a good key to the genus. I identified this beetle by going through drawers of Lebiini at the Smithsonian. Note the squared-off elytral tips, bright metallic color, thin green pronotum, and general elongate form. (I can't believe I was in high school when I found this beetle. How time flies!) Also, see the comments at the bottom of image below for more info on the identification and ecology of this neat beetle.
