This sample has been singled out from 10861 ATLASGAL clumps. All of these sources are not associated with any known star-forming activities collected in SIMBAD and young stellar objects identified using color-based criteria. We also make sure that the HMSC candidates have neither point sources at 24 and 70 \\micron~nor strong extended emission at 24 $\\mu$m. Most of the identified HMSCs are infrared ($\\le24$ $\\mu$m) dark and some are even dark at 70 $\\mu$m.
