Hobgoblins

Hobgoblins were larger, stronger and more menacing Goblins, mentioned by Gandalf the Grey when he describes the creatures inhabiting the Wilderland.

Many of them are probably some form of Uruk-hai or simply larger and thougher Orcs living in the wilderland. There is however no specific orc-race called Hobgoblins but it is simply the name for all larger kinds of Orcs, used in The Hobbit.
