The Tribes and Castes of the Central Provinces of India,...

The Korwas do not admit outsiders into the tribe. They will take food from a Gond or Kawar, but not from a Brāhman. A man is permanently expelled from caste for a liaison with a woman of the impure Gānda and Ghasia castes, and a woman for adultery with any person other than a Korwa. Women are tattooed with patterns of dots on the arms, breasts and feet, and a girl must have this operation done before she can be married. Neither men nor women ever cut their hair.
