Note.

Say (1830c: 19) noted that " H[arpalus] iricolor , Say, has been recently described by Dejean under the name of dichrous." I have not found any species described by Say under the name Harpalus iricolor . Say’s name has been listed as a junior synonym of Trichotichnus dichrous (Dejean) in several checklists but it is a nomen nudum as pointed out by Lindroth and Freitag (1969: 353).
