How to import category descriptions?

I'm moving a site to a different location, and wanted a fresh clean database to start with (after some problems with the previous one.) I exported everything from the original install, moved the site, and then imported the various xml files I had exported. All of that went fine.

Where I'm having a problem is with the category descriptions. They did not import. Everything else did. I have a directory that has about 80 categories, so I don't want to have to redo all of those. Is there a way to just import the category descriptions now that everything else has been imported?
