Precise eigenvalue asymptotics for a self-adjoint maximally hypoelliptic (with the loss of m/2 derivatives) operator \(A\in L^{M,m}(X,\Sigma,E)\) is presented where X is a compact closed manifold with a density, E is a fibering over X, \(\Sigma\) is a conic symplectic submanifold of \(T^*X\), m is an order of zero at \(\Sigma\) of the principal symbol a of A, a is of Mth order positively homogeneous symbol and lower order terms of A satisfy natural vanishing conditions at \(\Sigma\), \(M>m/2\).
