  We report multifrequency radio continuum and hydrogen radio recombination
line observations of HII regions near l=24.8d b=0.1d using the Giant Metrewave
Radio Telescope (GMRT) at 1.28 GHz (n=172), 0.61 GHz (n=220) and the Very Large
Array (VLA) at 1.42 GHz (n=166). The region consists of a large number of
resolved HII regions and a few compact HII regions as seen in our continuum
maps, many of which have associated infrared (IR) point sources. The largest
HII region at l=24.83d and b=0.1d is a few arcmins in size and has a shell-type
morphology. It is a massive HII region enclosing ~ 550 solar mass with a linear
size of 7 pc and an rms electron density of ~ 110 cm^-3 at a kinematic distance
of 6 kpc. The required ionization can be provided by a single star of spectral
type O5.5.
  We also report detection of hydrogen recombination lines from the HII region
at l=24.83d and b=0.1d at all observed frequencies near Vlsr=100 km/s. We model
the observed integrated line flux density as arising in the diffuse HII region
and find that the best fitting model has an electron density comparable to that
derived from the continuum. We also report detection of hydrogen recombination
lines from two other HII regions in the field.
