  We propose and prove a mirror theorem for the elliptic quasimap invariants
for smooth Calabi-Yau complete intersections in projective spaces. The theorem
combined with the wall-crossing formula appeared in paper (arXiv:1308.6377)
implies mirror theorems of Zinger and Popa for the elliptic Gromov-Witten
invariants for those varieties. This paper and the wall-crossing formula
provide a unified framework for the mirror theory of rational and elliptic
Gromov-Witten invariants.
