Can't seem to put a name on this one.
Do you have a ventral (wings closed) shot or even a dorsal shot (wings open)? What I'm seeing makes me think male Zabulon or Poanes zabulon. I think you had a female photo you posted not too long ago.
This poor photo is the only one one I have.
Thanks for posting the second photo. I'd definitely say Poanes zabulon. I've included a link from Bugguide. There are quite a few pages of pictures. I looked for images that matched yours as nearly as possible. I found several for both photos.
Here is a link that might be useful: Poanes zabulon dorsal view
