c. Only two setae of type 2. 
Gonodontis ( hidentata , formosa, ocellaria), Abbotana, Himera, 
Campcea ( Metrocampa ), Ellopia (not Therina), Selenia , Hygro- 
chroa, Stenaspilates, Hypoplectis, Scodiona, Hulstina, Amblychia 
(angeronaria ) , Xandr antes ( dholiaria ), Arichanna (transitional to 
Melanolophia group), Sarcinodes (unipectinate), Achlora (4- 
pectinate). 
Series II : Pectinations naked, cones at their apex. 
This series like the first is composed of three main groups, 
of which two are more like each other than to the third, and 
has some anomalous genera of uncertain position. Nacophora 
makes a group by itself, much like the Biston group, but differ- 
ing in egg-type as well as antenna. 
1. Basal segment of antennal shaft with well-marked pec- 
tinations; posterior series of longer pectinations than anterior, 
especially toward apex; cones very few, sometimes irregular in 
position and deformed. Apical setae of pectinations strong, 
strictly apical, and not obscured by setae of type 3; sub-apical 
seta strong, often arising well back from apex. Pectinations 
stout and long, tapering, with tips turned distad; strongly 
chitinized, especially at base, and longitudinally striate; shaft 
smooth or slightly granular. 
Nacophora (including u Amphidasys ” arnobia ), Phceoura. 
2. Cones numerous, normally on both series of pectinations; 
apical setae usually two, and well-marked. Tropical species fre- 
quently very heavily chitinized. American genera. 
Therina (including quercivoraria and Iceta), Nepytia, Zerene , 
Sicya, Philtrcea, Philedia, Nipteria (in part), Lissochares ( ni - 
grovenata), Deutophlebia ( radiata ), Emplocia (bupaloides) , Leucula 
(cillenaria) , Carpella ( distrida ), Sangalopsis ( beata ), — also “ Diop - 
tis” hesperioides, for which I have not happened to see a valid 
generic name, — Metanema {inatomaria and deter minata, transi- 
tional to group lie). 
3. Cones numerous on one series of pectinations, normally 
the posterior, usually absent on the other series, but present
