Description/
Field Marks:
FW middle portion of st. line or shade is more widely separated from the pm. line than in cochrusalis. The HW pm. and st. lines of cochrusalis tend to be more narrowly separated with pm. line bending more toward the apex. The HW pm. line tends to align with the FW st. line in cochrusalis and with the pm. line in trapezalis.
Genitalia: See Landry (2016); figs 109a-b, 158 and USNM illustrations.
