Blue Bycid: Callidium species

Dear Steve,
This is a gorgeous beetle in the family Cerambycidae, the Long-Horned Borer Beetles or Bycids.  We have it narrowed down to two genera.  Our first choice is the Blackhorned Pine Borer,
Callidium antennatum, which is pictured on BugGuide, or possibly Semanotus amethystinus, a species with no common name and also pictured on BugGuide.  We are contacting Doug Yanega at UC Riverside for assistance.

Blue Bycid: Callidium species

Doug Yanega responds.
Hi. I can confirm that it’s a female Callidium, but can’t be sure of species.
