Whoever has s*xual intercourse with a person who is and whom he knows or has reason to believe to be the wife of another man, without the consent or connivance of that man, such s*xual intercourse not amounting to the offence of rape, is guilty of the offence of adultery, and shall be punished with imprisonment of either descripttion for a term which may extend to five years, or with fine, or with both. In such case the wife shall be punishable as an abettor.
