Comments. Ch. (P.) leucops is very close to Ch. australis Dejean, 1831 in general habitus and colouration. It differs on the basis of pronotum more convex, densely covered with slightly smaller sized setiferous puctures; elytra slightly elongated; head and pronotum metallic blue green with slight tinge of bronze colour; elytra slightly greenish black and densely covered with golden pubescence. In Pakistan, leucops is recorded from the Islamabad and Attock areas. This is the first time this species is reported from Pakistan. It is widely distributed from Pakistan to all other south-east Asian countries.
