## Abstract:

The dimension of the vector space of hermitian modular cusp forms on the hermitian upper half plane can be obtained from the Selberg trace formula; in this paper we shall compute the contributions from conjugacy classes of regular elliptic elements in hermitian modular groups by constructing an orthonomal basis in a certain Hilbert space of holomorphic functions. A generalization of the main Theorem can be applied to the dimension formula of cusp forms of $SU(p, q)$. A similar theorem was given for the case of regular elliptic elements of ${\text {Sp}}(n, {\mathbf {Z}})$ in [**5**] via a different method.
