I think the word you want is apophasis.

a·poph·a·sis (ə-pŏf'ə-sĭs)
n.
Allusion to something by denying that it will be mentioned, as in I will not bring up my opponent's questionable financial dealings.

[Late Latin, from Greek, from apophanai, to say no : apo-, apo- + phanai, to say.]

From Atomica
