Notes on some Chalcid Parasites of Lac-Insects

Abstract

Many parasitic Hymenoptera are already known to live on lac-insects, and they are of importance either as noxious insects by destroying the Coccid (Tachardia lacca (Kerr)), or as useful insects when parasiting the predators of lac. As a result of the studies of Cameron, Imms, Misra and Mahdihassan, something is already known about them, but the systematic position and the identity of many of the species are still uncertain.
