Styling the last 5th li in my list

I’m running this website on wordpress and the list is generated by a plugin, however I can’t seem to change anything any of the styling on the last li tag.

HTML

<div class="home">
    <p></p>
    <h4><li><a class="wp-super-faq-question-closed" id="wp-super-faq-question--0" href="http://www.statics-wanted.co.uk/statics4cash/?wp_super_faq=earn-an-extra-750-for-your-static-genuine-additional-bonus" title="…Earn an Extra £750* for your static, Genuine Additional Bonus!!!”" rel="question"><span class="wp-super-faq-triangle">▶</span> …Earn an Extra £750* for your static, Genuine Additional Bonus!!!”</a></li></h4>
