Physocephala tibialis or Thick-headed Fly

Identification is tentative but probably correct or very close. It’s a wasp-mimic, but the eyes are distinctly those of a fly. It was strikingly beautiful in the field. It’s not a great photo, but its one of only two I got before it flew away. The colloquial name, while amusing, is not a pejorative but instead originates from the fact that the heads of these flies are always wider than the thorax.
