Histeridae?
Didn't measure it but my guess is approx. 5-10mm.
Resembles Platysoma at Cedar Creek here.

I now agree :-)
Obviously I was lower on the learning curve in Dec. 2005 but found my own P. gracile six-plus months later.

How about 4mm?
That would make it Cylistix sp., an histerid.

Platysoma is not elongate enough to be your beetle.

Synonyms
Don Chandler pointed out to me the following May that Cylistix and Platysoma are synonymous for this and other related "cylinderical" Histeridae.

4mm
Yes, it could easily have been 4mm. In this photo is was at the tip of a broken stem of a maple leaf I think, and that doesn't have a very large diameter.
