Right now, these small bronze metallic beetles are fairly common on new Yerba Santa (Eriodictyon trichocalyx var. trichocalyx) sprouting up in a recently burned area of coastal sage scrub at the Claremont Colleges' Bernard Field Station. I recently posted a photo of one, which was tentively identified as Hemiglyptus basalis. When I saw, however, that BugGuide has few photos of this species, I collected a few and chilled them before photographing them in order to contribute some clearer photos to the Guide. This one is still on its Yerba Santa leaf. I'd appreciate confirmation that I have them placed in the correct species!

Here's another individual collected from the same plant:
