A big beetle that was attracted to our porch lights. I found the following, remarkable information about this species on bugguide.net: "Notorious for emerging from furniture after as many as 10-40 yrs. Delayed emergence of E. quadrigeminata was discovered from a birch bookcase 40 years old (Jaques 1918)." The small photo below shows a magnified view of the large picture.
