Euagrotis gen. nov. 
Type, Noctua lubricans Gn. 
Eyes naked. Palpi upturned, with short, conical, somewhat porrected 
third joint; second joint heavily but smoothly scaled beneath with normally 
no indication of a triangular apical tuft; third joint smooth-scaled. Front 
smooth. Male antennae ciliate. Tibiae all spined; fore tibia subequal in 
length to first tarsal joint, smooth-scaled, with a weak hair-fringe on 
outer side; inner row of spines complete, outer row limited to two or three 
weak apical ones. Mid tarsi without fourth row of spines. Thoracic 
vestiture smooth, scaly, with practically no indication of tufting. 
Figure 21. Male genitalia of Euagrotis lubricans Gn. 
Male Genitalia. Clasper long and narrow, costa somewhat bulging at 
base and curving upward apically forming a blunt point with the apical 
margin; corona present and well developed; sacculus rather weak; harpe 
recurved, with slight bulbous base and with faint editum; occasionally 
traces of an ampulla. Uncus long and narrow, with recurved apical portion. 
Clavus strongly developed, broad. Juxta weak. Aedoeagus armed with 
a stout latero-apical spine, projecting from a chitinous plate of variable 
shape; vesica frequently armed with a finger-like chitinous rod. 
The following species are included in this rather homogeneous group 
which is probably a forerunner of, or an offshoot from, such species of the 
Agrotis group as ypsilon and malefida: lubricans Gn., illapsa Wlk., beata 
Grt. (both distinct from lubricans on genitalic characters), exuberans Sm., 
bairdi Sm. (the writer has not examined this but the figure indicates a 
close relationship to exuberans), simplicia Morr., digna Morr. (and prob- 
ably tenuescens Sm. which has not been seen), and finally tepperi Sm. 
which has very similar genitalia but has a strong fringe of hair on underside 
of second palpal joint and a better-developed fringe on outer side of fore 
tibia.
