In a search for lensed infrared galaxies, ISOCAM images have been obtainedtoward the rich clusters Abell 2218 and Abell 2219 at 15um. Nine galaxies (fourin Abell 2218 and five in Abell 2219) were detected with flux levels in therange 530-1100 microJy. Three of the galaxies detected in Abell 2218 havepreviously known redshifts; of these one is a foreground galaxy and the othertwo are lensed background galaxies at z=0.474 and z=1.032. One of the objectsdetected in the field of Abell 2219 is a faint, optically red, extremeinfrared-dominated galaxy with a probable redshift of 1.048.Comment: 10 pages of text, 6 figures. Requires aaspp4.sty. To be published in the Astronomical Journal, July 199
