The antennae are definately distinctive on this little beetle. I'm interested to find out what this might be. Thanks

Scirtidae
I'm pretty sure this is a "marsh beetle", family Scirtidae, but without a good match here in our collection or a good look at its ventral surface, I can't guesstimate a generic assignment. A pretty critter, though!

cheers,

 
Helodidae.
Ok, I was thinking of the Helodidae, which is what Scirtidae used to be called (Scirtidae is actually a conglomeration of at least two prior families). This particular beetle is a male Prionocyphon, probably P. discoideus. There are only two species in the genus, and apparently only discoideus has the feathery antennae in the male.

Brain cramp:-)
A-a-a-ugh! I recognize tihs, and it is a new family for Bugguide I'm pretty sure, just can't recall which one. Need find!
