[Newbie] Deleting maven archetype

I created a new Maven archetype by choosing File | New Project ...| (Maven) then clicking the "Add archetype..." button.  However, I made a typo in filling in the archetype form fields.  I didn't see a way to edit the archetype after I created it, so I created a new (second) one with the correct info.  Is there a way to delete the bad archetype I created?  (Right clicking it nor pressing delete on it seemed to do anything).

Thanks in advance,
Rogelio
