BOGOTA, Colombia (AP) _ Maria del Rosario Casas Ames, who was arrested this week with her CIA husband on spy charges, comes from an elite Colombian family and socialized with such literary figures as Gabriel Garcia Marquez.

Her arrest made headlines in Colombia, where the local press dubbed her a ''Colombian Mata Hari.''

The daughter of a former governor of Tolima state, Mrs. Ames earned a graduate degree in philosophy and taught literature and classical Greek at Bogota's University of the Andes during the late 1970s and early '80s.

In 1982, she was appointed cultural attache in Colombia's embassy in Mexico City.

There, she reportedly met her husband, CIA counterintelligence expert Aldrich Hazen Ames, and got on the agency's payroll.

The Colombian government issued a formal request Wednesday asking the United States to clarify whether Mrs. Ames was working for the CIA while in the Colombian embassy and explain what her husband did while in Colombia.

It added that Colombian judicial authorities have been ordered to investigate whether Mrs. Ames violated any Colombian laws.

El Tiempo, Colombia's largest-circulation newspaper, showed a front-page photo of a haggard Mrs. Ames being escorted into a car in Virginia, trying to shield her face from photographers with a sheaf of papers.

''Colombian Mata Hari Falls in the U.S.,'' the paper declared in a headline.

El Espectador showed a photo, apparently taken years earlier, of a smartly dressed Mrs. Ames, her hair cut into a bob, gazing at the camera.

''The person whom I would have least suspected of something like this was Doctor Rosario,'' said former Colombian ambassador to Mexico Ignacio Umana de Brigard, who had been Mrs. Ames' boss in Mexico City.

''She was extremely diligent, very efficient and, during her tenure in the embassy, showed herself to be very intelligent,'' Umana de Brigard told El Espectador.

Mrs. Ames' former colleagues described her as a quiet academician whose acquaintances included such renowned Latin American authors as Gabriel Garcia Marquez and Alvaro Mutis.
