Genus Prochloridea B. & McD. This genus has been placed in the Heliothiinae but after a study of the genitalia of a male of madonna B. & L., which is probably only a form of the genotype, modesta B. & McD., I believe it should be either placed next or sunk to Rhizagrotis as the genitalia show an extraordinary similarity to those of cloanthoides Grt., the genotype. I have already commented on the position of Rhizagrotis in the “Canadian Entomologist”, 1927, page 64, and restricted it to the species cloanthoides Grt. and albalis Grt.; the structural details of these two species fit in very well with the characterization of Prochloridea.
