Luminous, massive star are tracers of recent star formation in our Galaxy; they map out the spiral arms and reveal young clusters. Given their high luminosity, massive stars could, in principle, be observed in the optical passbands across the Galaxy were it not for the presence of obscuring interstellar dust. Because of this dust, the census of massive stars in our Galaxy is woefully incomplete (~ 90 % are undetected). In the near infrared the extinction is much lower, and the presence of strong emission lines allows the identification of evolved massive stars. We have obtained images in the inner Galaxy and near the Scutum arm with narrow band filters on the lines of He I, He II, Br (gamma), and C IV, which are most effective at identifying evolved massive stars in the 2(micron) window. We have obtained follow-up spectroscopy for the inner Galactic sample, and have discovered 4 previously unknown WR stars. Here we propose to obtain follow-up spectroscopy for our images near the Scutum spiral arm (l=316), thus completing follow-up observations for our photometric sample.
