Tachysphex?
Most likely a male Tachysphex, but not positive. Genera are determined in large part by the shape of the ocellar scars (ocelli are rudimentary if not entirely absent, but there are 'scars' where they used to be). I can't make that out in these images, obviously:-)

Thank you Eric
for the genus ID, I've added a head-on shot that might help confirm the ID.
