scarab beetle

6109  Measuring 3 cm in length, we found this bug (a beetle?) in our finished basement, in Toronto, ON, in August. It has been a rain-filled summer and the basement has definitely felt damp. Can someone help me identify what it is?  Thanks,  Laura

Like no. 6105, this is a scarab beetle (Coleoptera: Scarabaeidae) in the genus Osmoderma; see https://tinyurl.com/ycmskym6 for an example. It is strictly an accidental ‘visitor.’  Ed Saugstad, retired entomologist; Sinks Grove, WV.
