Narrative:

We were arriving into lax at XA00 am. I was captain and the PNF. We were flying the redeye 2 arrival. We were then cleared direct to smo. Cross smo at 8000 ft, then descend to 4000 ft. As we approached smo, approach asked us our speed. I responded 300 KTS. It was at this time that I realized that we were level at 8000 ft. I had been so concerned with the descent profile and the crossing altitudes, that I did not notice the speed leaving 10000 ft. Some factors that may have led to this include: our flight was delayed leaving chicago, leading to our being approximately 2 hours late. We were both becoming very tired. I live on the east coast. This led to our XA00 am lax arriving being more like XD00 am on my body clock. Due to being tired, it was becoming very easy to lose the scan, and to zone in on 1 or 2 items. Flying on the back side of the clock or the back side of your body clock, can have some very insidious consequences.
