This is the second of these guys I have seen in my basement. It made so much noise climbing through some files I thought it was a rat. Even lifted a plastic cup and got out of it. Has pinchers in the front and this one is prob about an inch long give or take a bit.
This is one of the Ground Beetles in the genus Scarites, probably Scarites subterranus, the Big Headed Ground Beetle. According to BugGuide, the Big Headed Ground Beetle has a “Distinctive body form and huge jaws, elytra deeply striated.” Like other Ground Beetles, they are predatory and considered beneficial.
