Abstract
Four species belonging to genus Theretra Hübner of family Sphingidae have been collected and explored from north-west Himalaya, India during different seasons. These species were examined on the basis of their distribution, synonymy, morphological characters (antennae, labial palpi, legs, wing venation) and their genitalic characters.
