[3.3.3] B2Evo Generated 404 page - how to edit?

My b2evolution Version: 3.3.3

Afternoon,

I just noticed that B2evo generates it's own 404 message if it can't find something - http://geeg.info/index.php/eee

The error is plenty sparse - and I'd like to edit it - does anyone know where this code is located?

/skins/_404_something.php

Thanks - I don't know how I missed that .....

much obliged.
