Just because Catholics don't have a Mass for Mary doesn't mean that they aren't guilty of worshiping her, by praying to her for help, succor, and salvation, and ascribing powers, glory, praises, and some titles to her, that rightfully belong ONLY to her Divine Son! Catholics are NOT off the hook about this, just because they don't do Masses for Mary
A Mass "in honor of" Mary is certainly allowed.
