We report the discovery of two new transiting planets from the WASP survey. WASP-42 b is a 0.500±0.035M_J planet orbiting a K1 star at a separation of 0.0548±0.0017AU with a period of 4.9816872±7.3x10^–6-days. The radius of WASP-42 b is 1.080±0.057R_J while its equilibrium temperature is T_eq=995±34K. We detect some evidence for a small but non-zero eccentricity of e=0.060±0.013. WASP-49 b is a 0.378±0.027M_J planet around an old G6 star. It has a period of 2.7817387±5.6x10^–6 days and a separation of 0.0379±0.0011AU. This planet is slightly bloated, having a radius of 1.115±0.047R_J and an equilibrium temperature of T_eq=1369±39K. Both planets have been followed up photometrically, and in total we have obtained 5 full and one partial transit light curves of WASP-42 and 4 full and one partial light curves of WASP-49 using the Euler-Swiss, TRAPPIST and Faulkes South telescopes.
