Varro does not feature for the remainder of the Second Punic War, though later held two roles in the year 200 BC. He was part of a three-man diplomatic legation to North Africa, tasked with visiting Carthage, and senior Numidians. The ambassadors were instructed to inform Carthage that, despite the conclusion of the war in 201, the general Hamilcar was continuing operations in Gaul and that Romans who had deserted to Carthage had not been repatriated. Furthermore, they took gifts and congratulations to Masinissa, whose alliance with Rome had proved pivotal at the Battle of Zama, on his becoming King of Numidia.
