The writer has already pointed out (1927, Can. Ent. LIX, 66) that 
Hampson’s usage of this generic term was incorrect and that Eurois should 
include occulta Linn., astricta Morr., and nigra Sm. The latter two species 
agree very closely with the genotype in all features except palpal vestiture, 
having a heavy fringe of hair beneath which is lacking in occulta. To these 
species is added, for the present, docilis Grt., which is decidedly atypical in 
form of genitalia but otherwise agrees pretty closely; the genitalia of this 
species, in fact, are more like those of Richia, but such an association is 
scarcely advisable and, rather than create a new generic term, it is left in 
Eurois. Praefixa Morr., which the writer does not know, may also fall here; 
Smith suggests that it is identical with docilis (Jour. N.Y. Ent. Soc. XV, 
148, 1907). 
Ochropleura Hbn. 
1822, Verz. bek. Schmett. 223 (type, plecta Linn.). 
Eyes naked. Palpi upturned, with third joint conical, slightly por- 
rected; second joint heavily but smoothly scaled. Front smooth. Male 
antennae fasciculate. Tibiae all spined; fore tibia longer than first tarsal 
joint, smooth-scaled, with a complete inner row of lateral spines, but with 
the outer row reduced to two or three apical ones; all these spines rather 
weak. Fourth row of tarsal spines lacking. Thoracic vestiture smooth, 
scaly, with no appreciable tufting. 
Figure 19. Male genitalia of Ochropleura plecta Linn. 
Male Genitalia. Clasper long, narrow, with corona; harpe a recurved 
hook, situated slightly beyond apex of sacculus, but connected with it by 
an oblique bar of chitin; at the connecting point a small spine near ventral 
margin of clasper. Uncus rather shorter than in Agrotis. Clavus moder- 
ately well developed, broad at base, tapering apically. Juxta weak, slightly 
pointed at base. Vesica armed with a huge cornutus.
