Surrounding Custom Post Type with Custom Div

Hi VedaThemes
I am trying to surround a widget output of Custom Post Types with a div with a few custom classes that vital to the appearance of my theme. How would I go about surrounding the following code:

<section id=”dpt_display_post_types-4″ class=”widget display_posts_types clearfix”>…</section>

I looked at all the plugin files and can’t figure out which hook would display Custom Post Type as a widget.
