chiasmus

In rhetoric, chiasmus is the figure of speech in which two clauses are related to each other through a reversal of structures in order to make a larger point; that is, the two clauses display inverted parallelism. Chiasmus was particularly popular in Latin literature, where it was used to articulate balance or order within a text. [from http://en.wikipedia.org/wiki/Chiasmus]
