I only know of a few. My cousin's a member of PSA, which is a political science honours society. I don't think their members do much, as he and his class were inducted just before he graduated. On my campus we have chapters of HSF, LS, PSA Mortar Board, FBK and PKL. HSF is an honours society for Latin and Greek scholars. As far as I know, people of any year can be inducted. They help with Classics week every spring. LS is a sophomore honours society; members are inducted at the end of their freshman year and they do quite a bit in terms of campus/community service and fundraising. Mortar Board is more or less the same, but it's for seniors. Along with campus/community service, they sponsor a lecture series. As for FBK and PKL, they're both groups for outgoing seniors (PKL is an honours society for music majors), so they don't really do much on campus.

Hope this helps a little...
