Earlier in the thread I guessed Aster, because that was a name on the Wikipedia site for tricycles powered by de Dion motors. I notice on the Georgano entry for Phebus that the company's full name was Phebus-Aster. Don't worry, I'm not claiming anything, but does anyone know the full story here? The posted period advert for the Phebus shown above does not even mention the Aster name.
