Simultaneous UBVRI and MNQ photometry is combined with existing JHKL data to determine flux distributions for several southern R Coronae Borealis (RCB) stars. Blackbody approximations to the flux distributions indicate circumstellar material temperatures in the range 650-900 K for most RCB stars. The hot candidate RCB star, MV Sgr, has strong infrared excess at 10 microns and displays evidence for a cool (less than about 500 K) as well as hot (approximately 1600 K) component to its circumstellar shell. DY Cen appears to be hotter (approximately 10,000 K) than normal RCB stars and may be more closely related to MV Sgr.
