We found this Beetle in our garage. It is May 2016, about 445p in Whittier, CA.
It was between some boxes on the floor.
We looked at your site and think it’s a Stink Beetle but weren’t 100% sure.

Dear Cunningham Family,
This is one of the Caterpillar Hunters in the genus Calosoma, and interestingly, we just posted a gorgeous image of a relative known as the Fiery Searcher. We have always considered the black Caterpillar Hunters found in Southern California to be Calosoma semilaeve, though the species is not represented on BugGuide. BugGuide now has a posting of a black member of the genus from Southern California that is identified as Calosoma parvicolle and we would not entirely rule out that as your species.
