The only ones of that list I've never used are the Intellect Devourer and the Tarrasque.
As for the rest:
Black Pudding - was in the adventure just completed; the party saw it as a "pool of oil", got suspicious, and intentionally avoided it.
Gelatinous Cube - is in the next adventure, and appears anywhere I need to spice up a trap.
Carrion Crawler - haven't used for a while as they don't present much of a threat; last seen maybe 6 years ago.
Mind Flayer - are the foot-soldiers of some major behind-the-scenes villain(s) in this campaign, so can appear at any time.
Roper - last seen maybe 11 years ago (maybe the Storoper version?). I really should toss a few more of these in now and then.
Umber Hulk - was in the adventure just completed; the party learned of it before getting to its location, and intentionally avoided it.
Mimic - was in an adventure about a year ago but by sheer luck the party completely missed it. It was very disappointed.
Rust Monster - last seen about 2 years ago when I jumped to running a low-level party for a while.
Displacer Beast - I know I've run these within the last decade but can't honestly remember when.
Beholder - last seen about 4 years ago.
Marilith (or other big-ass demon that can really bring the nasty) - last seen about 5 years ago when Pazuzu showed up.
