Demonology is the study of demons and the Devil.

It is often connected with witchcraft, such as in The Encyclopedia of Witchcraft and Demonology. (TXF: "Sanguinarium")

For two days in 1999, Frank Black was logged on to websites dealing with possession, demonology, exorcism and millennial prophecy. Special Agent Del Boxer learned this by spying on Frank Black and later told Agent Emma Hollis the same information. (MM: "Seven and One")
