This was actually discussed on this list only two weeks ago, funnily enough.

The solution that seemed satisfying was an :nth-match(num, selector)
pseudoclass, which would work exactly like :nth-child except it would
only 'count' elements that also matched the selector.

Your example would be handled as "li:nth-match(2, .new)".
