Extra space in header (left of logo and right of search bar).

I am certain that I've overlooked something obvious. But after substantial time rooting around in the theme options, I can't figure out how to get rid of the extra space at the left and right at the very top of the header (left of the logo and right of the search bar). You can see what I'm referring to here.

Thanks for any pointers about how to get rid of the extra space.
