  Ro-vibrational spectra of different electronic states of molecules are often
used as absolute wavelength or frequency standards. These standards are also
used to mitigate any slow drift of laser frequency during an experiment. In
precision experiment, the two most commonly used molecular standards are iodine
and tellurium, both are homo-nuclear diatomic molecules. The former is mostly
used as standard for the long wavelength ($600-900$~nm) region, while the
tellurium spectrum is widely used in short wavelength ($400-550$~nm) including
near ultra violet. A comprehensive data on tellurium spectra can be obtained
from the tellurium atlas~\cite{Te2atlas:80}. However near the $455~$nm range
where a number of important atomic resonance line, the atlas provides no
significant data. We have performed high resolution modulation transfer
spectroscopy~(MTS) on tellurium molecule in a hot cell in the region close to
$455~$nm wavelength thereby obtained more than $100$ new spectral lines which
were not observed before. The resolution of each of these peaks is about few
MHz, making them suitable for laser frequency locking.
