was a colleague of Cicero in the praetorship, B. C. 66, and presided over cases of peculatus. He is called by Q. Cicero "civis ad anmitionem gratiosissimus" (Cic. Clu. 34, 53; Q. Cic. de Pet. Cons. 5.19). The name is also written Orchicius and Orcinnius, but Orcivius seems to be the correct reading. (See Orelli, Onom, Tullian. s. v.)
