excurved above, incurved below vein 4; subterminal line defined only by a black costal patch before it and 
another beyond it at middle; orbicular and reniform with black centres and ochreous annuli outlined with 
black; the former small, produced externally to a slight point; a black streak in cell between them; hindwing

minal area beyond it dark; claviform stigma black, extending from base to middle of wing; orbicular and reni¬ 
form black or with the centres black, the grey annuli with black outlines; the orbicular elongate, produced 
to a point, confluent with reniform or connected by a black streak; hindwing fuscous; fringe ochreous with 
brown line at base; the ab. rufescens (= ab. 1 Hmps.) has the head and thorax and forewing more uniform rufesccns. 
reddish brown; the base of tegulae not dark, as in the type; the veins of forewing concolorous, not grey; the 
claviform stigma not filled in with black. Hawaii. 
E. dislocata Walk. (6 h). Forewing pale ochreous; the costal and inner marginal areas brownish grey; dislocata. 
veins black interlined with white; the lines absent; a dark point in cell; claviform stigma brown outlined with 
black, elongate, and continued backwards to base as a narrow streak; orbicular and reniform brown outlined 
in black; the orbicular elongate and confluent with reniform, which is somewhat tridentate, being produced 
to a point above vein 5; slight dark streaks sometimes present above bases of veins 2 and 3; a terminal series 
of black points; hindwing fuscous; fringe whitish with a brown line at base. Hawaii. 
E. aulacias Meyr. (6h). Forewing brown suffused with reddish, the veins greyish white; the inter- aulacias. 
spaces with obscure blackish streaks; a series of terminal black points; hindwing brown; fringe brown with 
pale basal line. Hawaii. 
Sect. V. Antennae of <$ simply ciliated. 
E. reclusa Walk. (6 h). Forewing reddish brown, irrorated and striated with fuscous; the lines indistinct; reclusa. 
the inner double, waved, marked with dark spots at costa and on submedian fold; the outer minutely waved, 
excurved to vein 4, thence oblique; subterminal preceded by fuscous suffusion which is strongest at costa; 
orbicular and reniform with fuscous centres, their annuli defined by brown, the former round and indistinct; 
hindwing brown, whiter towards base; fringe whitish, with a brown line through it. Australia. 
E. nyctina Hmps. (6i). Forewing narrow, the margins subparallel; fuscous redbrown with dark irrora- nyctina. 
tion; inner and outer lines both indistinct; the inner oblique, angled on submedian fold, the outer outcurved 
to vein 4, then incurved; subterminal line curved, defined by a dark shade preceding it; stigmata with dark 
centres and outlines; hindwing fuscous grey. Described from a single $ from Kumaon in the Ralam Valley. 
2. Genus: Khyacla Hbn. 
Differs from Euxoa in having the frons smooth, without any corneous processes; as in that genus, it 
is divided into sections according to the differences in antennal structure; it includes Hampson’s three genera. 
Agrotis, Epipsilia, and Lycophotia, the differentiation of which depends in the main on the character of the 
clothing of the thorax. Type R. lucipeta Schiff.
