Omoglymmius, wrinkled bark beetle (Rhysodini). California.

Rhysodine beetles make their living feeding on slime molds under the bark of decaying trees .  They are instantly recognizable from the grooves on their backs and from their distinctly moniliform (bead-like) antennae.  The taxonomic placement of these insects is controversial, but genetic evidence suggests they are a highly specialized lineage of Carabidae, the ground beetles.

    I have these crawling around one of my cupboards and in a dresser drawer.

    Any way to rid them? I have no idea how they came to me, since I live on the 10th floor of my building.
