Dear Sir/Madam:

     On  behalf  of  the  IDEX  Series  Fund  (the  "Fund"),  we  are  filing  a
certification  pursuant to paragraph (j) of Rule 497 under the Securities Act of
1933.  In this  regard,  we  certify  that the form of  Prospectus  for the Fund
otherwise  required to be filed under  paragraph  (c) of Rule 497 would not have
differed  from the form of  Prospectus  contained in the Form N-1A  registration
statement  for  the  Fund  (the  "Registration  Statement").   The  Registration
Statement was filed  electronically  with the Securities and Exchange Commission
on February 27, 1998 via EDGAR.

                                              Sincerely,


                                              /S/
                                              Gayle Morden
                                              Compliance Supervisor
