  which time must be not more than 4 months after the date of issuance.

  general description of all other persons belonging to the class, showing

    (b) Where the persons to be served are unknown, a general  description
  of such persons, showing their interest in the proceeding.
    In  either of such cases, where the petitioner is ignorant of the name
  of a person to be served, he may designate that person in  the  citation
  by a fictitious name or so much of his name and identity as is known.
