New almost-degenerate charged and neutral heavy leptons are a feature of anumber of theories of physics beyond the Standard Model. The prospects fordetecting these at the Large Hadron Collider using a time-of-flight techniqueare considered, along with any cosmological or experimental constraints ontheir masses. Based on a discovery criterion of 10 detected exotic leptons weconclude that, with an integrated luminosity of 100 fb-1, it should be possibleto detect such leptons provided their masses are less than 950 GeV. It shouldalso be possible to use the angular distribution of the produced particles todistinguish these exotic leptons from supersymmetric scalar leptons, at abetter than 90% confidence level, for masses up to 580 GeV.Comment: 15 pages,8 postscript figure
