We were on the TYSSN3 arrival into LAS; ATC kept giving us directs; taking us off the arrival. They asked if we had the field in sight and we confirmed that we did have it in sight and they cleared us direct SHAND and the visual 25L. The First Officer asked for 5;000 FT; the published altitude for SHAND. He continued his gradual descent to 5;000 FT and maintained 250 KTS; intending to slow down at 5;000 FT to help expedite our late arrival into LAS. It was a clear night with a half moon; I believe. At no point did I consider terrain separation an issue. However; on our dog leg to final; I noticed after we landed that on the [Commercial chart] page it does show a rising terrain with a top elevation of 3;738 FT just south of LARRE. I believe this is what we flew over and my guess is that the rapidly rising terrain is what caused the EGPWS to activate the 'Too Low; Terrain' call. He disconnected the autopilot and autothrottles and climbed to approximately 5;600 FT; again with everything in sight (airport; city lights; terrain). I do believe the long day we had; being 2 hours late and it being after XA00am also played a factor.
A320 Captain reported receiving a EGPWS Terrain alert on night visual approach into LAS while being vectored off arrival routing. Fatigue was mentioned as a factor.
