Our method for selecting white dwarf candidates is based on a combination of theoretical color-magnitude relations and reduced proper motion diagrams. We reported in an earlier publication the discovery of nearly 200 new white dwarfs, and we present here the discovery of an additional 133 new white dwarfs, among which we identify 96 DA, 3 DB, 24 DC, 3 DQ, and 7 DZ stars. We further identify 178 white dwarfs that lie within 40pc of the Sun, representing a 40% increase of the current census, which now includes 492 objects. We estimate the completeness of our survey at between 66% and 78%, allowing for uncertainties in the distance estimates. We also perform a homogeneous model atmosphere analysis of this 40pc sample and find a large fraction of massive white dwarfs, indicating that we are successfully recovering the more massive, and less luminous objects often missed in other surveys. We also show that the 40pc sample is dominated by cool and old white dwarfs, which populate the faint end of the luminosity function, although trigonometric parallaxes will be needed to shape this part of the luminosity function more accurately. Finally, we identify 4 probable members of the 20pc sample, 4 suspected double degenerate binaries, and we also report the discovery of two new ZZ Ceti pulsators.2015ApJS..219...19Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/219/19CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/235 : Spectroscopically Identified White Dwarfs (McCook+, 2008)I/298 : LSPM-North Catalog (Lepine+ 2005)II/299 : GD blue stars from Lowell proper motion survey (Giclas+ 1980)J/MNRAS/446/4078 : New white dwarf stars in SDSS DR10 (Kepler+, 2015)J/AJ/147/129 : White dwarfs within 25pc of the Sun (Sion+, 2014)J/ApJS/204/5 : SDSS DR7 white dwarf catalog (Kleinman+, 2013)J/MNRAS/435/2077 : Properties of Sirius-like binary systems (Holberg+, 2013)J/ApJ/765/12 : Carbon stars & DQ white dwarfs from SDSS-DR7+DR8 (Green, 2013)J/AJ/145/136 : Astrometry & phot. of nearby white dwarfs (Limoges+, 2013)J/AJ/145/102 : Bright M dwarfs spectroscopy in northern sky (Lepine+, 2013)J/AJ/143/103 : New white dwarfs (Sayres+, 2012)J/AJ/143/50 : White dwarfs in 47 Tuc (NGC 104) with HST (Woodley+, 2012)J/ApJ/760/26 : DA white dwarfs infrared photometry (Barber+, 2012)J/ApJ/743/138 : Spectroscopic survey of bright white dwarfs (Gianninas+, 2011)J/AJ/142/138 : All-sky catalog of bright M dwarfs (Lepine+, 2011)J/ApJ/730/128 : Spectroscopy of DA WD from the SDSS-DR4 (Tremblay+, 2011)J/ApJS/190/77 : Detailed analysis of cool WDs in the SDSS (Kilic+, 2010)J/MNRAS/402/620 : SDSS WD main-sequence binaries (Rebassa-Mansergas+, 2010)J/A+A/505/441 : UVES/VLT spectra of white dwarfs (Koester+, 2009)J/AJ/135/1225 : Parameters of the local white dwarfs (Holberg+, 2008)J/MNRAS/382/515 : SDSS ultracool and halo WD candidates (Vidrih+, 2007)J/A+A/470/1079 : UVES/VLT spectroscopy of white dwarfs (Voss+, 2007)J/ApJ/663/1291 : DZ stars in SDSS DR4 (Dufour+, 2007)J/AJ/132/1221 : VJHK and SDSS photometry of DA white dwarfs (Holberg+, 2006)J/ApJ/643/402 : Cool white dwarfs in the solar neighborhood (Kawka+, 2006)J/AJ/131/582 : Cool white dwarfs in the SDSS (Kilic+, 2006)J/ApJS/167/40 : SDSS4 confirmed white dwarfs catalog (Eisenstein+, 2006)J/ApJS/156/47 : DA white dwarfs from the Palomar Green Survey (Liebert+, 2005)J/AJ/124/1190 : Northern high proper motion stars in DSS (Lepine+, 2002)J/A+A/378/556 : UVES/VLT spectra of white dwarfs (Koester+, 2001)J/ApJS/133/413 : BVRIJHK photometry of cool white dwarfs (Bergeron+, 2001)http://www.astronomy.villanova.edu/WDCatalog/ : White dwarf cataloghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/219/19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/219/19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/219/19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/219/19https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/219/19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/219/19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/219/19/table2 (Spectroscopically confirmed new white dwarfs from SUPERBLINK -
