Agreed.
This beetle appears to be out of range, i.e. not in California or Oregon, and exhibits three physical traits more in line with T. femoratus:

1. Red femur, not black
2. Hairyness, instead of being smooth.
3. Small spots near end of elytra, as opposed to large spots

While not an expert, I've shot a lot of T. basalis recently. We have one other post that seems to be similarily mis-identified, and I've notified the contributor.
