:last-child

Matches all elements that are the last child of their parent.
While :last matches only a single element, this matches more then one: One for each parent.
Examples:

Finds the last span in each matched div and adds some css plus a hover state.

    $("div span:last-child")
        .css({color:"red", fontSize:"80%"})
        .hover(function () {
              $(this).addClass("solast");
            }, function () {
              $(this).removeClass("solast");
            });
