Another new one!
These bombadier beetles are one of my favorite genus, and I'm glad they're getting identified. Thanks Peter.

Brachinus vulcanoides
based on my microscopic examination of this specimen. Helpful clues to identity include location (northeastern USA), the color pattern of antennae and an especially deep constriction of the pronotum. Hidden in this image are protibiae with smooth surfaces, i.e., the absence of minute linear ridges seen in similar species. Thanks Tom.
