All available observations of the energy distributions of 53 Tau and κ Cnc from the wavelength interval between Lα and the Paschen jump are compared with a series of model atmospheres in which temperature, microturbulent velocity and chemical composition were varied. Good agreement is obtained if effective temperatures of 53 Tau and κ Cnc are 11,250 K and 12,800 K, respectively, and the chemical compositions are taken from Strom (1969) and Kodaira (1965). New chemical compositions obtained by Heacox (1979) produce too much blanketing in UV, particularly for κ Cnc. For 53 Tau the set with υmicr = 0 gives equally good fit as the old abundances and the resulting temperature is 11,400 K. Observations of both stars show a slight excess of radiation in the red. It is suggested that this excess may be caused by the circumstellar matter.
