He was also called Hybrida (of mixed race) because his mother was from Hispania.
[1][2] Quintus Varius Severus Hybrida was from Sucro, Hispania (in eastern Iberian peninsula, in the contemporary municipality of Albalat de la Ribera) and was the first senator of the Republic to come from the province of Hispania.
He wrote a law, the lex Varia, in order to punish all those who had “assisted” those who took up arms against the Roman people.
[3] In practice it was used to prosecute those who had supported giving the Socii citizenship.
[3] As a result, many distinguished senators, among them Gaius Aurelius Cotta, were sent to exile.
