This is Grammia phyllira. Here are some ways to distinguish the two:

In G. parthenice the transverse line (pale bar) at the end of the discal cell is bent toward costa, whereas phyllira has a straight transverse line leaning more toward the apex.

Also, phyllira has deeper pinkish red hindwings than parthenice, whose hindwings are a lighter salmon color. The thin lines (which are veins with light colored scaling) can be present or absent in phyllira. G. parthenice also has a fairly thick pale fringe (concolorous with transverse lines) on the terminal border of FW, whereas phyllira does not.

Lastly, parthenice has a strong pale border (concolorous with transverse lines) along the entire FW inner margin (even merging with terminal fringe), whereas in phyllira this border tapers off just past half way from the base, before reaching the FW tornus.

Hope that helps. :)
