sagittate marks generally also. Hindwings white, sometimes impure white and occasionally with dark margin. 
A dark marginal line, fringes white. South France, Spain, Caucasus'?, Sarepta ? Early stages unknown. 
E. rangnowi sp. n. (4 f £ type). Larger and of greater expanse than tritici. Similar to vitta Him. Fore¬ 
wings pale red-brown intermixed with white. Costa dusted with white, also orbicular and reniform stigmata, 
white spots on costa. A black basal streak, the cell below same dark brown, attached to same the very dark, 
large claviform stigma. Outer transverse line faint, double. Subterminal line whitish, distinct sagittate marks. 
Hindwings of almost pure white, abdomen grey-white. No discoidal spots. L T nderside without bands and 
markings. South Urals, Guberli, July. Early stages unknown. 
E. diaphora Brs. (= capita Corti i. 1.) (4 g type). Stouter and more compactly built than tritici L. 
Fore wings much wider, dark red-brown, markings distinct, median nervure dusted whitish. Orbicular and 
reniform stigmata small, filled with pale brownish, inner and outer transverse lines, dark claviform stigma, paler 
subterminal line. Sagittate marks present. Hindwings pure white with scarcely any black margin, sometimes 
however margin very dusky. Underside of wings pale, hindwings almost white, both with a marginal line 
consisting of small lunules. Sarepta, southern Urals, Sebastopol. Early stages unknown. 
E. riphaea Bart. (4 k rf). Similar to tritici, but still more so to deserta Stgr. and homicida Stgr. in size, 
colour and marking. Forewings uniform grey-brown, transverse lines very indistinct, marginal line yellowish. 
Antennae as in tritici. Hindwings almost pure white with very faint dark marginal line. Underside of wings 
as in tritici but paler, homicida Stgr. has more heavily pectinated antennae. Urals, August. Early stages unknown. 
E. philippsi Corti (5 a C type). Similar to the previous species and to homicida Stgr. Antennae like 
homicida. Hindwings pure white as riphaea Bart. Underside of forewings with distinct and rather large brown 
central spot, homicida and riphaea have hairy scales and scales on thorax, whilst philippsi has mainly only 
scales which widen considerably upwards and have a short protruding spine in the indentation. Sarepta. 
E. cortii Wgnr. (4 g £ cotype). Similar to homicida Stgr. Differing from same by the pure white hind¬ 
wings in both sexes. Antennae much less heavily ciliate and pectinate than in homicida and deserta. Forewings 
paler or darker sand (or clay) coloured, sometimes as if powdered over with flour. Extinct transverse lines in 
basal and marginal areas. Stigmata outlined by fine but distinct dark lines. Reniform stigma always filled 
with dark scales at its lower extremity. In marginal area a pale subterminal line which is shaded with brownish 
towards the base. Marginal line yellowish; sharply, defined sagittate marks. Undersides of fore and hindwings 
whitish with silky gloss. Central lunule shadowlike or absent. Early stages unknown. Inner Anatolia. August 
and September. 
E. fallax Ev. (Vol. 3, p. 33) (4h $). Palpi white, underside white with inclination to dusky grey, 
forewings whitish grey. 
E. sulcifera Chr. (Vol. 3, p. 33). According to Kozhantschikov, this is no genuine Euxoa. 
E. costaevittata Wgnr. (4 g $ cotype). Varies to a considerable degree. Grey to blue-brown. Forewings 
with wide pale costal streak, distinct blackish spots between orbicular and reniform stigmata. In place of 
claviform stigma, a small black spot displaced towards the base and a row of distinct blackish sagittate marks 
in front of margin. Hindwings in both sexes pure white with very fine marginal line which may be absent. 
Underside white with silky gloss, darker specimens with brown suffusion at apex and at marginal area of fore¬ 
wings, as well as a shadowy arched line there. Central lunule only indicated, generally quite absent. Resembles 
vitta Him. Early stages unknown. Inner Anatolia. 
E. claricostata Corti (4g J type). Similar to tritici L. Grey to blue brown; paler costa; reniform and 
orbicular stigmata with whitish circumference and pale centres, claviform stigma large, but generally rather 
obscure. Median nervure whitish from reniform stigma to base. The oblique pale stripe downwards from 
claviform stigma, which is generally characteristic of aquilina forms, is nearly always distinct. Sagittate marks 
present, they are situate in a paler patch and are edged by a whitish undulate line outwardly. A fine yellowish 
marginal line, fringes dark. Hindwings of $ almost white, somewhat darker at edge and along veins, in $ 
considerably darker. Underside of forewings dusky, of hindwings whitish with a fine discoidal dot on same. 
Early stages unknown. Urals, Sarepta, July and August. 
The classification here of the following 3 species is perhaps not correct, possibly they should be placed 
to islandica Stgr., but more probably they are related to north american species. 
E. opipara Morr. (Vol. 3, p. 32, pi. 6 i). This is not synonymous with norwegica Stgr. Warren’s de¬ 
scription can be supplemented as follows: reminds one of well marked specimens of vitta. Basal area often with 
heavy white patches, inner transverse line undulate, double, edged with whitish inwardly; outer transverse line 
clearcut, dentate outwardly. The area between the two transverse lines dark, the outer area is then pale like
