of the same colour and edge. A pale marginal line, fringes of same colour as wings. Hindwings almost uni¬ 
coloured, heavily adumbrated, somewhat paler in median area. Distinct discoidal spot. Fringes impure white. 
Underside almost plain grey-white. Fore wings with a shade, discoidal spots indistinct. Altyn-tag, Alexander 
Mountains, Aksu. 
E. (?) achyricola sp. n. (4 d type). Similar to decora but smaller. Forewings narrower, more pointed, 
inner transverse line situate further outward. Hindwings impure white, thorax pale grey. Underside of wings 
much paler than in decora, arched stripe almost completely absent. Northern Syria, Marash; July (Peiffer). 
The following species classified as Euxoa in the main Volume under Section IV, p. 28 etc. do not belong here but 
to subsequent Genera: submolesta Ev., cursoriodes Hmps., viguraea Pglt., moechilla Pglr., subdecora Stgr., clauda Pglr., gri- 
sescens F. , parnassiphila Stgr., cucuna Pglr., decoratci Stgr., simploma Stgr., constanti Mill., trux Hb., seditiosa Pglr., nili 
Baker, nigrita Graes., solida Ersch., iristis Stgr., sulcifera Chr., arenosa Stgr., lidia Cr., xanthoides Hmps., honesta Stgr., duo- 
sigma Hmps., informis Leech and exclamationisL.: on the other hand oberthuri Leech, intracta Wkr. and impexa Pglr. are 
Euxoa of the following Section: 
Section VI: antennae of the <$ with short pectinations with cilia. 
The following species without a direct transition from the last species of the preceding Section. 
E. intolerabilis Pnglr. (Vol. 3, p. 31, pi. 6 h) (= percurrens Corti i. 1.) The illustration is good, only 
as a rule the markings are less distinct and the colouration more monotonous. Early stages unknown. 
E. predotae Schaw. (4 d $). Somewhat like intolerabilis Pnglr. and still more like fissa Stgr. but dif¬ 
fers from the latter by the more pronounced markings and a violet golden colour tone. Antennae are coarser 
and thicker than in intolerabilis and fissa. Transverse lines double, a dark marginal band is present, that 
is absent in intolerabilis. Claviform stigma scarcely indicated. A few small yellowish spots on costa of fore¬ 
wings. Hindwings grey-brown with distinct discoidal lunule. Underside of wings almost unicolourous dark 
grey with distinct arched band and dark discal lunule on hindwings. Ussuri, Siberia, Mongolia (Urga, Kozh.). 
August-September. Early stages unknown. 
E. nigricans L. (Vol. 3, p. 30, pi. 6 h). (= fumosa Him., rustica H.-S., ursina God., fuliginea Hbn., 
carbonea Hbn., uniformis Rgt., oppidicola Krul. sec. Koziiantschikov and Filipjef). The specimen illustrated 
in the main Volume is a relatively reddish one, as a rule nigricans is much darker, very often quite black, 
so that the markings are scarcely discernible, nigricans varies in colour and marking quite considerably, so that 
a large number of aberrations have been denominated (vide main Volume). Chiefly it is the transverse bands 
and the stigmata that vary, sometimes they are absent, sometimes more or less visible, now black and again 
white or orange or prominent in some other way. The most striking form is — ab. (ab. et var. sec. Stgr.) 
rubricans Esp. with pale reddish wings. This form occurs everywhere among nigricans and is therefore simply 
an aberration. Perhaps the japanese nigricans forms a genuine subspecies. They are larger, darker, very 
often with reniform stigma with red or reddish centre. It occurs besides in Central Europe, in England and 
W. Asia, also in Spain, Italy, the Balkans, PTrals and E. Asia. Of the early stages, the ova are not described. 
The brown pupa in an earthern cocoon with 2 cremaster spines. 
E. (sec. Tams) nyctopis Hmps. (Vol. 3, p. 31, pi. G i). The illustration is too grey, the colour should be 
much more red-brown, the markings are too distinct. The species is perhaps only a reddish nigricans race 
from Kashmir. The form mentioned by Hampson as ab. 1 with dark brown forewings and transverse lines edged 
with whitish has been named - kuijat’ensis by Strand. 
E. adumbrata Ev. (Vol. 3, p. 28, pi. 6 b). Related to nigricans and tritici. Kozhantschikov considers 
adumbrata to be a subspecies of lidia Cr., which is erroneous, lidia has quite different antennae and entirely 
different genital organs than adumbrata. On the other hand I am of the same opinion as Christoph and 
Sptjler that the v. polygonides Stgr. (Vol. 3, p. 28) is a genuine separate species. — vaga Stgr. (Vol. 3, p. 30) 
(4 d C) (— Integra Corti i. 1.). This form, hitherto always classified as a variety of cursoria, should actually 
be classified to adumbrata. It is a completely pale brown, almost luteous form of adumbrata. Staudinger already 
questioned whether vaga should be placed with cursoria. The variety originates from the Ulias and also Thi¬ 
bet. The early stages of adumbrata are unknown, Graeser thinks he can remember that the larvae have 
great similarity to those of fennica Tausch. Flight: June-July. 
E. latebrosa sp. n. (4 d <$ type). Similar to adumbrata but much paler, almost pale grey, the mark¬ 
ings much more distinct, stigmata with white centres, margin of forewings grey, of hindwings white. The 
latter also in $ sex much paler, sometimes completely white in <$. Claviform stigma almost always distinct, 
blackish to black, the cell between orbicular and reniform stigmata filled with black creating a likeness to 
recussa. No sagittate spots present. Naryn, Turkestan. Early stages unknown. 
E. goetria Kozh. (4 d <$). Antennae of with rather frailer cilia than adumbrata. Very similar to this 
species, has a dark, sharply outlined streak from base of forewings to beyond claviform stigma. Orbicular 
and reniform stigmata edged with black outwardly, with white inwardly, orbicular stigma is open at upper 
end. Transverse lines more or less distinct, sagittate spots almost always present. Hindwings grey, at base
