Male Genitalia. Clasper moderate in width with slight bulge about 
the middle of costa; apex rounded, without corona, but with a strong 
pollex projecting forward from lower angle; sacculus strong; harpe weak, 
much as in Pachnobia, with the distal portion of the foot-like attachment 
obsolescent; editum present. Clavus obsolescent. Juxta armed with a 
strong apical spine. Uncus narrow. Tegumen with its base (ventral side) 
broadly truncate. Aedoeagus long, narrow, armed apically with a spined 
chitinous band ; vesica with small bulbed cornutus. 
This genus, which is erected for monochromatea, is distinctly allied to 
Pachnobia and Anomogyna in type of genitalia, the harpe and aedoeagus 
being notably similar. The complete spining of the fore tibia, however, 
and the presence of the fourth row of tarsal spines make the separation 
from both of these genera advisable. 
Paradiarsia gen. nov. 
Type, Agrotis littoralis Pack. 
Eyes naked. Palpi upturned, with third joint somewhat porrect; 
second joint with long rough fringe of hair beneath; third joint smooth- 
scaled. Front smooth. Male antennas bipectinate. Tibiae all spined; 
fore tibia longer than first tarsal joint and with a complete row of spines 
on the inner side; several apical spines and a fringe of hair on the outer 
side. Mid tarsi with a fourth row of spines on outer side laterally. Thor- 
acic vestiture hairy and rough, without distinct tufts. 
Figure 27. Male genitalia of Paradiarsia littoralis Pack. 
Male Genitalia. Clasper narrow with very pointed apex and neither 
corona nor pollex; harpe well developed; connected more or less with apex 
of sacculus by a curved rod of chitin; a small chitinous mound with patch 
of hair at inner base of harpe probably represents the editum. Clavus 
obsolescent. Juxta with strong finger-like projection. Uncus very thin 
and long. Vesica armed with a long spiculate chitinous band. 
The sole species, littoralis Pack., seems sufficiently distinct from other 
members of the Graphiphora group to warrant the new generic name. The 
four rows of tarsal spines, the hairy vestiture, and the bipectinate male
