Abstract:
    In this paper, we have searched for the Two Micron All Sky Survey
    (2MASS, Cat. II/246) counterparts of 1434 BL Lacs. 833 of 1434 BL Lacs
    (58%) have spatially coincident 2MASS counterparts. Fermi-detected BL
    Lacs (FBLs) have a much higher 2MASS detection rate than
    non-Fermi-detected BL Lacs (non-FBLs) (95% vs 49%).
