Psilogramma menephron, the privet hawk moth or large brown hawkmoth, is a member of the family Sphingidae.

It is usually found in Sri Lanka, India (including the Andaman Islands), Nepal, central and southern China, Thailand, Vietnam, Indonesia and the Philippines.

Psilogramma casuarinae from eastern Australia was long treated as a synonym but is now thought to be a distinct species.

Dark brown bands along the sides of palpi and thorax meet on metathorax, where there are a few blue and yellow scales.

[3] Larvae have been recorded on Clerodendrum fortunatum, Ligustrum species (including Ligustrum sinense), Fraxinus, Jasminum, Tectona grandis, Vitex negundo, Callicarpa arborea, Lonicera, Perilla and Osmanthus sesamum.
