During its EUV all-sky survey, the wide field camera (WFC) on the ROSAT satellite discovered several new AM Herculis type stars. In this paper, we present observations of RE0751+14, RE1149+28, RE1844-74, RE1938-46, and RE2107-05. Using the International Ultraviolet Explorer (IUE), spectra were obtained of these systems over a band pass of 1200-3400 angstroms. These AM Her stars, discovered in the EUV, and faint at optical wavelengths, proved to be bright UV emission line sources. The intensities of the individual emission lines due to CIV, CII, NV, HeII, and SiIV are 1.5-3 times stronger then usually seen. However, the equivalent width ratios of these same emission lines are similar to those seen in typical AM Hers. Using additional observations of these stars in the EUV, we compare the continuum flux of the new AM Hers at optical, UV, and EUV wavelengths to previously studied AM Hers, and discuss some of the implications of these data.
