When you're working with a set of definitions and not merely an list of unordered items.
A <dl> is a definition list. It should be used in such a case as, perhaps, a dictionary:
Use-case:
<dl>
<dt>Thesaurus</dt>
<dd>A book for finding synonyms of other words, often alphabetical. Similar to a dictionary.</dd>
</dl>
Result of the above:
<dt> element, and the definition of that term is given in the <dd>.
A <ul> is an unordered list. Now, a <dl> does not imply any order to its contents, but it does imply a semantic relation between its children. A <ul>, however, could contain anything that is not ordered.

Here are two (from here):
