In Raigarh the Kharias have only two subtribes, the Dudh, or milk
Kharias, and the Delki. Of these the Delki are said to be of mixed
origin. They take food from Brahmans, and explain that they do so
because an ancestress went wrong with a Brahman. It seems likely
that they may be descended from the offspring of immigrant Hindus in
Chota Nagpur with Kharia women, like similar subdivisions in other
tribes. The Delkis look down on the Dudh Kharias, saying that the
latter eat the flesh of tigers and monkeys, from which the Delkis
abstain. In Bengal the tribe have two other divisions, the Erenga
and Munda Kharias.
