another one of these:

 
Yes
That is probably male in the Stenodynerus anormis-group. We have seen several come in from California this year. We're waiting for Dr. Buck or another expert to review them, before placement in that group. (most likely)

 
so i guess this median macula rules out Euodynerus
makes sense, thanks

Female
She looks basically the same as the first one:

 
Yes...
...and, really, the only noticeable difference to me is the clypeal markings (this one has a small black triangle in the middle of an otherwise yellow clypeus, while the other specimen has a much larger, quadrate black zone surrounded by yellow). I wasn't sure if this small difference would make them different species (or genera, for that matter). But I would think they are at least the same genus.
