We present a list of candidate gravitationally lensed dusty star-forming galaxies ( DSFGs ) from the HerMES Large Mode Survey ( HeLMS ) and the Herschel Stripe 82 Survey ( HerS ) . Together , these partially overlapping surveys cover 372 deg ^ { 2 } on the sky . After removing local spiral galaxies and known radio-loud blazars , our candidate list of lensed DSFGs is composed of 77 sources with 500 \mu m flux densities ( S _ { 500 } ) greater than 100 mJy . Such sources are dusty starburst galaxies similar to the first bright Sub Millimeter Galaxies ( SMGs ) discovered with SCUBA . We expect a large fraction of this list to be strongly lensed , with a small fraction made up of bright SMG-SMG mergers that appear as Hyper-Luminous Infrared Galaxies ( HyLIRGs ; L _ { IR } > 10 ^ { 13 } L _ { \odot } ) . Thirteen of the 77 candidates have spectroscopic redshifts from CO spectroscopy with ground-based interferometers , putting them at z > 1 and well above the redshift of the foreground lensing galaxies . The surface density of our sample is 0.21 \pm 0.03 deg ^ { -2 } . We present follow-up imaging of a few of the candidates confirming their lensing nature . The sample presented here is an ideal tool for higher resolution imaging and spectroscopic observations to understand detailed properties of starburst phenomena in distant galaxies .
