This word is a reflexive pronoun, normally used in a sentence with I as the subject (I hurt myself). The use of myself for me as the object of verbs or prepositions is nonstandard; say "The supervisor spoke to Jane and me (not myself)." Also, do not use myself as the subject of a verb; say "The policeman and I saw the accident," not "The policeman and myself saw the accident." See also him.
