He was suffect consul in the nundinium of September to December 124 as the colleague of Gaius Julius Gallus.
[3] Due to the lack of information about Severus, experts have attempted to identify him with the subject of less well preserved inscriptions.
For example, Ronald Syme noted that an inscription from Thubursicum concerning [...]rius Severus could detail an otherwise unknown portion of his career, which lists offices that include "Legate of Lycia-Pamphylia, consul, legate of one of the two Germanies, proconsul of Africa ....
A priesthood, that of sodalis Hadrianalis, standing in the praetorian posts of his cursus along with XV vir s. f.." However, Syme admits that the first part of his name could be restored another way, such as [Elf]rius Severus, the name of two other attested men of this period.
"[4] A second proposed identification is by N. Lamboglia, who restored Severus' name in a fragmentary and mutilated inscription from Albenga.
