John J. Droney, district attorney of Middlesex Country, said yesterday that last night's screening of "The Devil in Miss Jones" at Quincy House represents a criminal offense, calling the film "an obscene movie which of course shouldn't be shown."

Droney said, however, that he would take no action to prohibit Quincy House from showing the film.

Massachusetts State Superior Court Judge Vincent Brognia yesterday ordered a temporary ban pending an appeal on the showing of "The Devil in Miss Jones," "Behind the Green Door" and "Deep Throat" in Boston, Fitchburg and Stoneham.

Borgnia's order came in a 12-page decision that concluded that according to present Supreme Court standards the films are not obscene.

George Byrne, district attorney of Suffolk Country--who along with Droney and the Worcester Country district attorney brought the suit--said yesterday that the district attorneys will appeal Brognia's decision to the U.S. Supreme Court.

A spokesman for the Quincy House Film Society, who refused to be named, said yesterday that the society categorically advocates college-level sex education, and added, "I just hope we get through this."
