A scarecrow. Bug is the Welsh bwg, a hobgoblin, called in Russia buka. Spenser says, “A ghastly bug doth greatly them affear” (book ii. canto 3); and Hamlet has “bugs and goblins” (v. 2).
Pope: Satires, iii. 67–68.
⁂ The latter half of this word is somewhat doubtful. The Welsh bár = ire, fury, wrath, whence barog, spiteful, seems probable.
