Catus, Firmius
a senator, was the accuser of Scribonius Libo Drusus in A. D. 16. A few years afterwards (A. D. 24), Catus was condemned by the senate to be banished to an island, on account of a false accusation of majestas which he brought against his sister; but in consequence of his former service in the accusation of Drusus, Tiberius remitted his banishment, but allowed him to be expelled from the senate. (Tac. Ann. 2.27, 4.31.)
