  A rare group of high mass X-ray binaries (HMXBs) are known that also exhibit
MeV, GeV, and/or TeV emission ("gamma-ray binaries"). Expanding the sample of
gamma-ray binaries and identifying unknown Fermi sources are currently of great
interest to the community. Based upon their positional coincidence with the
unidentified Fermi sources 1FGL J1127.7-6244c and 1FGL J1808.5-1954c, the Be
stars HD 99771 and HD 165783 have been proposed as gamma-ray binary candidates.
During Fermi Cycle 4, we have performed multiwavelength observations of these
sources using XMM-Newton and the CTIO 1.5m telescope. We do not confirm high
energy emission from the Be stars. Here we examine other X-ray sources in the
field of view that are potential counterparts to the Fermi sources.
