Origin and Etymology of cephus
borrowed from New Latin, perhaps extracted from Greek kēphḗn “drone bee” ◆Genus name introduced by the French entomologist Pierre André Latreille (1762-1833) in Histoire naturelle, générale et particulière des Crustacés et des Insectes (“Sonnini’s Buffon”), vol. 3 (Paris, An X ), p. 303. Latreille gives no clue to the origin of the name, which replaces Sirex pygmaeus of Linnaeus.
