  We report the discovery by the WASP transit survey of two new highly
irradiated giant planets transiting moderately bright stars. WASP-64b is
slightly more massive (1.271+-0.068 M_Jup) and larger (1.271+-0.039 R_Jup) than
Jupiter, and is in very-short (a=0.02648+-0.00024 AU, P=1.5732918+-0.0000015
days) circular orbit around a V=12.3 G7-type dwarf (1.004+-0.028 M_Sun,
1.058+-0.025 R_Sun, Teff=5500+-150 K). Its size is typical of hot Jupiters with
similar masses. WASP-72b has also a mass a bit higher than Jupiter's
(1.461-0.056+0.059 M_Jup) and orbits very close (0.03708+-0.00050 AU,
P=2.2167421+-0.0000081 days) to a bright (V=9.6) and moderately evolved F7-type
star (1.386+-0.055 M_Sun, 1.98+-0.24 R_Sun, Teff=6250+-100 K). Despite its
extreme irradiation (about 5.5 10^9 erg/s/cm^2), WASP-72b has a moderate size
(1.27+-0.20 R_Jup) that could suggest a significant enrichment in heavy
elements. Nevertheless, the errors on its physical parameters are still too
high to draw any strong inference on its internal structure or its possible
peculiarity.
