This is the second fascicle treating a portion of the New World apameine moth fauna. The North American species of the genera Amphipoea Billberg and Hydraecia Guenée are reviewed, and the genera Cherokeea Quinter & Sullivan, Franclemontia Ferguson, Papaipema Smith, Parapamea Bird, and Selicanis Smith (Noctuidae: Noctuinae: Apameini) are fully revised. Three new genera are described: Arundinariaphila Quinter (type species: Arundinariaphila hayesi Quinter), Fibigeria Quinter (type species: Gortyna erepta Grote), and Sarita Quinter (type species: Acrapex relicta Ferguson).
Seventy-seven species are treated, eleven of which are described as new: Arundinariaphila hayesi Quinter; Cherokeea gabrielleae Quinter; Cherokeea odonnellae Quinter; Cherokeea slotteni Quinter; Papaipema albimontana Quinter; Papaipema amianthii Quinter; Papaipema blackorum Quinter; Papaipema hesseli Quinter; Papaipema matheri Quinter; Papaipema sablensis Quinter; Papaipema sullivani Quinter. Three new combinations are created: “Resapamea” trigona (Smith) is transferred to Cherokeea, “Amphipoea” erepta (Grote) to Fibigeria, and “Acrapex” relicta (Ferguson) to Sarita. Two neotypes and three lectotypes are designated. Three species are raised from synonymy: Papaipema rubiginosa Bird, Papaipema birdi (Dyar), and Papaipema depictata Benjamin. Gortyna aerata Lyman is deemed to be a hybrid of P. cataphracta × necopina and is placed into synonymy as an unavailable name.
Numerous new life histories are reported. Adults and genitalic structures of all species are illustrated in colour, and their larvae, where known, are as well. Keys to all genera are included, and species keys to adults, where practical, are included. Keys to larvae are included wherever sufficiently known. Selected images of habitats and host plant symptoms of larval damage are presented in colour.
