Scientific paper

VBLUW photometry of the long-period Cepheid in the LMC G458 = HD270100 with a period P of 74.0 d is presented. The characteristics in the two color diagrams suggest that its metal abundance is higher than that for the other LMC Cepheids. A theoretical HR diagram is presented which indicates the fundamental blue edge, some P = constant lines for the second crossing, and the position of the two Cepheids G 458 and HV 2827.
