Before 333,[4] Adelphius was corrector of Apulia et Calabria, with the see of his office at Beneventum, where he was a patron too. In 351 he was proconsul of an unknown province, probably Africa, and he was already married to Proba. From 7 June to 18 December 351 he is attested as praefectus urbi of Rome, under the usurper Magnentius. In this period he was accused by some Dorus of conspiring against Magnentius; it is probable that this accusation was true, as shown by the fact that Proba wrote a poem celebrating Emperor Constantius II's victory over the usurper.
