Goliath Beetle (Goliathus), a genus of tropical Lamellicorn beetles, in the sub-family Cetoniidae. They are distinguished by their large size, by the horny processes on the heads of the males, and by the toothed lower jaws or maxillæ. Several species frequent tropical and South Africa, and related genera occur in tropical Asia. The male of the largest form, Goliathus druryi, from the Gold Coast, measures about four inches in length. In colour, as well as size, these goliaths and their relatives are splendid insects. The family Cetoniidae is familiarly represented in Europe and Britain by the Rosechafer (Ctonia aurata).
