Species of Rodolia Mulsant (1850) are important as predators of mealybugs, some of which are notorious for their injury to plants. Rodolia cardinalis Mulsant is a classical example of a species that has been successfully introduced into several countries against the cottony-cushion scale, Icerya purchasi Maskell. A campaign against the latter, in South India, has be.en in progress for some time, and a number of local Coccinellid predators, collected by the staff responsible for the work, were sent for identification to the Commonwealth Institute of Entomology. The present study is based mainly on this material, and also on that in the British Museum (Natural History). All the known Indian species are redescribed and three new ones added to the list.
