We investigate the charmless decays of excited P-wave charmonia 
and 
via intermediate charmed meson loops, where V and P denote the light vector and pseudoscalar mesons, respectively. Within the model parameters, the charmed meson loop contributions are evaluated by using the effective Lagrangian approach. For , the partial widths of the 
, 
, and 
channels can reach to the order of MeV, while the partial width of the 
channel is very small and in the order of keV. For 
, the partial widths of 
turns out to be sizeable, while the partial widths of 
is found to be much smaller than the 
channel. Our calculations may be examined by the future BESIII experiments.
