Catocala grotiana : the original description states “My specimen is a ♁ in good condition, and was taken in Colorado .” We have been unable to locate a specimen labeled as type, and the Bailey collection is apparently lost. Although usage of the name grotiana has been largely consistent during the last century, since the name refers to a member of the taxonomically diffi cult and variable western Nearctic species, we designate a female from the AMNH as neotype to clarify application of the name grotiana . Th e neotype bears the labels “ Colorado .”, “No. 12652 / Collection / Hy. Edwards.”, “Edw. Coll.”, “Catoc. / grotiana / Bailey.” Type Locality: remains Colorado , [ USA ] on the basis of the neotype labels.
