1. n. A chronic disease of the feet and hands occurring in Hindustan. The foot (or hand) becomes riddled with sinuses which discharge pale-yellow masses of minute bodies resembling fish-roe (pale or ochroid form of mycetoma), or dark masses resembling gunpowder (dark or melanoid form). In the latter the fungus Chionyphe Carteri has been found. The disease lasts for decades, and the only relief seems to be in the amputation of the affected member. Also called Madura foot, Madura disease, fungus disease, and fungus-foot of India.
2. n. [capitalized] In entomology, a genus of coleopterous insects.
