Something that is allusive contains (or is characterized by) indirect references. Someone or something that is elusive is hard to describe or skillful at avoiding capture. See Allude & Elude.
Examples:
Merdine called attention to the biblically allusive title of the White Stripes' CD Get Behind Me Satan. The lyrics to some of their songs are fragmented, mysterious, and elusive.
Practice:
(a) Bob Lind sang about "the bright _____ butterfly of love."
