Male Genitalia. Clasper rather short and broad, rounded apically, 
without corona; digitus present, situated subapically near costal margin; 
sacculus strongly developed, asymmetrical, continued from about the middle 
of the ventral margin to just before apex of clasper by a broad chitinous 
band somewhat recurved and free at apex; harpe a strong, obliquely placed 
chitinous rod, rounded apically and attached at base, not to the sacculus

direct, but to the chitinous band forming the extension of same. Uncus 
rather short, broader than usual, and truncate apically. Clavus absent. 
Juxta strongly chitinized, rear margin of plate strongly convex, apical 
margin concave. Aedoeagus with apical edges strengthened by a thicken- 
ing of the chitin; vesica with minute apical spine. 
The great divergence in the genitalia of balanitis , the sole included 
species, from those of either Chorizagrotis or Euxoa, makes a new generic 
term advisable. In some w'ays the species seems to be a connecting link 
between Chorizagrotis and Graphiphora, but sufficient characters in the front- 
al and palpal structure on the one hand and in the spining of the tibise and 
tarsi on the other hand may be found to separate the present genus from 
both of the others.

Type, Agrotis proclivis Sm. 
Eyes naked. Palpi upturned, the third joint more or less porrect; 
second joint fringed with hair below, tending to form a triangular tuft 
apically; third joint smooth-scaled. Front bulging and roughened, but 
without central tubercle. Male antennae typically serrate and fasciculate 
(often merely ciliate). Tibiae all spined; fore tibia slightly shorter than 
first tarsal joint, smooth-scaled, with a complete row of spines on each 
side, these rather weak except the apical ones which are strong and claw- 
like. Mid tarsi with at least a partial fourth row of spines laterally on the 
outer side. Vestiture of thorax largely scaly with the tufting generally 
improminent.
