You did it wrong. You don't have to put a local name if you are using public box (e.q. named with a slash like "<account>/<box>").
Try to do this and confirm that it completes without error:
Code:
vagrant init parallels/ubuntu-14.04
vagrant up
But in case if you are using your custom box, then the command you've provided is correct: "vagrant init <local_box_name> <box_url_or_path>"
So, seems like you have an error while working with your own custom box. It might be caused by a syntax error in another Vagrantfile, which is bundled with a box. Please, find it and show the content:
Code:
cat ~/.vagrant.d/boxes/analytics/0/parallels/Vagrantfile
