decidedly longer and narrower, and the armature of the vesica consists of a 
single short bulbed cornutus. The clavus is small but rather broad. 
Under this generic heading are included the species: ducens Wlk., 
hudsoni Sm., evanidalis Grt., subgothica Haw., herilis Grt., pectinicornis 
Sm., edentata Sm. (not examined), annexa Tr., and geniculata G. and R. 
The genus could readily be sunk to Agrotis; it is retained, however, for the 
ducens group on the strength of the slight genitalic differences, as well as 
modifications of the palpi and male antennae. 
The two last species are aberrant. A}inexa shows a roughened front 
and the fore tibia has stronger terminal spines; in the genitalia the 
aedoeagus does not appear to possess any armature. Geniculata is only 
doubtfully placed here, as the antennae are not bifasciculate; however, 
taking into consideration the armature of the aedoeagus and the shape of 
the clavus no better position could be found. The genitalia are very 
close to those of manifesta and acarnea.

Eyes naked. Palpi upturned, with conical third joint slightly por- 
rected; second joint heavily but smoothly clothed with scales beneath; 
third joint smooth-scaled. Front smooth. Male antennae ciliate. Tibiae 
all spined; fore tibia slightly longer than first tarsal joint, smooth-scaled 
with a complete row of well-developed spines on each side, terminating 
in a stronger spine. Mid tarsi with a fourth row of spines as in Agrotis . 
Vestiture of thorax scaly, smooth, with slight median anterior and divided 
posterior tufts. Abdomen rather flattened.
