Asbolus

In Greek mythology, Asbolus (English translation: "sooty" or according to Dieter Koch, "carbon dust") was a centaur. He was a diviner who read omens in the flight of birds. When Heracles came to visit the centaur Pholus, Pholus opened a jug of wine for him which belonged to all the Centaurs; Asbolus saw Pholus do this and brought the other Centaurs running. The party got rowdy and a battle ensued in which Pholus and Chiron, as well as Nessus, met their deaths at Heracles' hands.
