  We give a combinatorial description of the rational cohomology of the moduli
spaces of pointed genus 1 curves with $n$ marked points and level $N$
structures. More precisely, we explicitly describe the $E_2$ term of the Leray
spectral sequence of the forgetful mapping
$\EuScript{M}_{1,n}(N)\to\EuScript{M}_{1,1}(N)$ and show that the result is
isomorphic to the rational cohomology of $\EuScript{M}_{1,n}(N)$ as a rational
mixed Hodge structure equipped with an action of the symmetric group
$\mathfrak{S}_n$. The classical moduli space $\EuScript{M}_{1,n}$ is the
particular case N=1.
