Hobgoblins

Hobgoblin was a name "for the larger kinds" of Orcs found in Middle-earth in the Third Age. The term perhaps, but doubtfully, refers to the large soldier-orcs known as Uruk-Hai.

The term appears so rarely that there is little clear basis for a definition. Its only other occurrence is later in The Hobbit (Chapter 7: "Queer Lodgings") where Gandalf warns Bilbo Baggins that the Grey Mountains are 'simply stiff with goblins, hobgoblins, and orcs of the worst description'.
