Near midair collision between a beech 35 bonanza descending to land behind another aircraft on final and a C172 coming in the opposite direction. The reporter took evasive action in order to reduce a potential collision. When the tower controller was advised of near midair collision, he advised that the C172 was 1 mi south of where the location was reported to the tower.

Narrative:
I (small aircraft) had flight following to boise. I had been handed off to boise tower by boise approach. Boise tower cleared a king air for landing on runway 10L. I was cleared by boise tower for #2 behind the king air. My passenger shouted, I looked directly ahead and saw a cessna single. It had already started evasive action. I informed the tower and they asked me what a new C172 looked like and that he was 1 mi south of his reported position. His heading at the time was 280 degrees, mine was 100 degrees.
