One similar species from this genus (found in India) is Hemaris tityus, but the moth in your picture doesn't look exactly like this particular species. Another similar species is Hemaris saundersii, which is found in and around India.

As suggested by @fileunderwater this moth belongs to the Sphingidae. It is Cephonodes hylas the Coffee bee hawkmoth, aka the pellucid hawk moth or Coffee clearwing. It is a largely distributed moth, found from the Middle east to Autralia.
