This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae) in the genus Monochamus, it looks like a northeastern pine sawyer, M. notatus – see https://tinyurl.com/y9huk6a3 for an image. This does not appear to be a serious pest, as its larvae bore in trees that already are dead or dying. Ed Saugstad, retired entomologist; Sinks Grove, WV.
