Thanks for the second shot.
I can't say I'm certain, but I'm still leaning strongly toward a Tenthredinid with broken antennae.

I suspect it's a Tenthredinid
A clearer view of the venation might settle the matter. Any other angles?

Acordulecera?
Probably identifying way deeper than my level of expertise can excuse. Definitely a hymenopteran, but the extremely heavy wing venation and constant-width abdominal segments makes me think this is a sawfly rather than a wasp. BugGuide claims that 6-segmented antennae are diagnostic of Acordulecera.

I agree with sawfly...
but I wonder if these antennae aren't just broken. They seem much thicker than those of any Acordulecera I've seen.

Makes sense
Especially given the flared appearance of the tips

Antenna
I believe the antenna are broken, one has more segments than the other. Looking through a key, I ended up with Pergidae
