How do I restore my mobileme mailboxes in iCloud's mail on iMac??

Question

I've gone through the migration process fairly smoothly except for the loss of access to my mailboxes/folders for what was my mobileme account and that is now my iCloud one. The folders are all intact and accessible via iCloud.com, but I would really like to have them again in Mac Mail. Thanks.

Triple-click anywhere in the line below on this page to select it:
~/Library/Mail/V2/MailData
Right-click or control-click the line and select
          Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Quit the application if it's running. Restore the selected item from a backup that predates the problem.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
