  We present an analysis of UVES and MIKE (ground based) high resolution and
Far Ultraviolet Spectroscopic Explorer spectra of two novel and photometrically
variable bright blue stars in the SMC; OGLE004336.91-732637.7 and the
periodically occulted star OGLE004633.76-731204.3. The light curves of these
stars exhibit multiple frequencies, and their spectra are similar. The latter
are dominated by absorption/emission features produced in a circumstellar (CS)
envelope whereas photospheric features are barely visible and forbidden
emission lines are not visible. Modeling of spectral features indicates similar
physical conditions for the CS envelope in both stars. An optically thick,
slowly and thermally stratified disk. OGLE004633.76-731204.3 is noteworthy in
showing blue discrete absorption components ("BACs") in their spectra possibly
indicating the shock interaction between high velocity and low velocity
material. Optical spectra from two spectra separated by 5 years show little
change in the radial velocity over this period. However because these
observations happen to be made in roughly similar phases over their long
period, these suggest only that the stars are not in close binaries. We
interpret the occultations and additional photometric nearly periodic
variability in OGLE004633.76-731204.3 as due to covering of the star by a
density modulation in a sector of a quasi-Keplerian circumstellar disk.
Altogether, we suggest that these stars are prototypes of a larger group of
stars, which we dub the "bgBe's" and discuss their similarities and differences
with respect to the well known sgB[e] variables. Although
OGLE004336.91-732637.7 appears to be a member the open cluster NGC 242, the
evolutionary context of these stars is unclear.
