Long Horned wood boring beetle

5618     Good Morning,   I found this bug in my kids bedroom crawling across the floor. Could you please identify for me?  Is it harmful? Thanks.
This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae) in the genus Monochamus. Known as sawyers, some species in this genus can be serious timber pests, but unless you count being nipped by their strong jaws, they are harmless to humans.
