In this article, we study the charmed baryon states and with the spin-parity 
by subtracting the contributions from the corresponding charmed baryon states with the spin-parity 
using the QCD sum rules, and suggest a formula 
with the effective mass 
to determine the energy scales of the QCD spectral densities, and make reasonable predictions for the masses and pole residues. The numerical results indicate that the and have at least two remarkable under-structures.
