nor as to whether the systematic position here is correct. Hampson places nomas among the species not dealt 
with by him, as a doubtful Orosagrotis (protuberant frons, all tibiae with spurs, head and thorax covered with 
hairs). These characteristics are certainly present and nomas also resembles quieta Him., but still more Agroti- 
phila staudingeri Mschlr., with which perhaps it is related. Kozhantsciiikov has examined the <$ genitalia and 
places nomas in the Genus Euxoa, but according to the illustration nomas appears to be a genuine Meseuxoa. 
The species is a small one of abt. 22—23 mm expanse, 26—27 mm according to Erschoff. Forewings and 
fringes dark ashy grey, basal line indicated by dark spots, the inner and outer transverse lines darker and more 
distinct with light edges, orbicular and reniform stigmata whitish with brownish centres, marginal area between 
the outer transverse line and the distinct sagittate marks much paler. Hindwings ashy grey, somewhat darker 
towards margin, fringes white. Underside pale ashy grey, a distinct band over both wings, more pronounced 
on forewings. Antennae of <$ shortly clavate instead of serrate and with long, dense pencillo-fibriatae. Ferghana, 
Turkestan in July. 
M. complicata sp. n. (5 d £ type). A larger species, abt. 42 mm. Antennae of $ very heavily serrate and complicala 
ciliated. Forewings almost uniform grey-brown, thorax similarly. No collar. Claviform stigma obsolescent also 
the basal transverse line, inner line distinctly double and pronouncedly concave, orbicular and reniform stigmata 
are scarcely visible being of the same colour as the wings with faint dark circumscriptions. A very pale faint 
subterminal line is present, marginal area being slightly darker. A clear yellow marginal line in front of which 
are small black lunules. Fringes somewhat paler than the wings. No sagittate marks. Hindwings monotonous 
brownish white, somewhat darker towards the margin; a yellow marginal line, fringes impure whitish. Underside 
of forewings glossy grey-brown, hindwings impure whitish, a band is indicated on same by dark streaks along 
the veins. Naryn, Turkestan. 
M. determinata sp. n. (5 d type). Slightly smaller than the previous species. Antennae of £ serrate deter- 
and ciliated. Thorax and forewings pale grey-brown, basal area and costa grey. Basal line indicated by a few minala 
distributed spots, inner and outer transverse lines distinctly visible, double, the outer one curving sharply 
inwards at inner margin. Claviform stigma scarcely visible, orbicular and reniform stigmata pale with blackish 
surrounds, the former round, the latter with black inner edge, almost open outwardly. Long and distinct 
sagittate marks. A blackish marginal line. Hindwings uniformly dull brownish grey with distinct angulated 
discoidal spot. Fringes impure white. Underside pale, dusky grey-brown with heavy discoidal arc on fore¬ 
wings. Tien-shan. 
M. fissa Stgr. (Vol. 3, p. 28, pi. 6 b). The illustration was poor, it is being repeated on pi. 5 e. A medium fissa. 
sized species, antennae of bipectinated, somewhat like in distinguenda Led. In colouration fissa seems to 
vary considerably. Staudinger speaks of a dusky dark grey colour of forewings, specimens from the Province 
Irkutsk, of which one is being illustrated, are brown to red-brown. The inner transverse line is double, very 
distinctly marked, sagittate marks are absent, median nervure pale. For other remarks compare Vol. 3. Apart 
from the antennae it might easily be mistaken for a small recussa Him., which possibly has induced the synonv- 
mising of decussa Stgr. with recussa Hbn. by Hampson. However decussa is neither an Euxoa nor a Meseuxoa. 
Wing expanse 31—35 mm. Uliassutai, Siberia, Turkestan. 
M. foeda Led. This species which I erroneously classified under Euxoa (Suppl. Vol. 3, p. 30) should be focda. 
placed with the subgenus Meseuxoa according to the structure of the copulation organs. 
M. hilaris Err. (= conifera Chr.) (Vol. 3, p. 31, pi. 6 i). Although this species varies considerably, the hilaris . 
illustration in the main Volume is not satisfactory and it is being repeated here (5 e). To be added to Warren’s 
description in the main Volume is that the transverse lines are usually very distinct. Forewings are inclined 
to reddish-brown rather than grey, claviform stigma generally distinct, hindwings pale grey-brown. Underside 
with distinct lunules and more or less pronounced bands on both wings. Freyer’s type originated from 
Constantinople. Specimens from Persia, which are somewhat darker are denominated by Strand as ab. persiae. persiae . 
Their claviform stigma is extinct, but this also occurs in hilaris and this designates Hampson’s ab. 2. The forms 
denominated by Warren from the Urals and having white hindwings must refer to some other species. In 
regard to the — ab. incognita Stgr. mentioned in the main Volume, both Hampson & Warren have erroneously incognita . 
classified same with hilaris ; incognita is a genuine species and synonymous with seditiosa Pglr. and elaborata 
Corti i. 1. This is a genuine Acjrotis (Feltia ) and is dealt with in that Genus. Asia Minor, Armenia, Persia, 
Turkestan, Altai, Siberia, Amur. It flies by day in June-Augusf. Early stages unknown. 
M. biscajarsa sp. n. (5 d, <§ cotype). Antennae of finely pectinated and ciliated. Similar to a tritici L.. biscajana . 
differing from same however by the entirely differently formed antennae. Fore wings pale reddish brown (it 
may be presumed that darker specimens also occur) intermixed with brown, basal line not visible, a dark basal 
streak is present, inner transverse line faint, claviform stigma distinct and from same to anal angle there is a 
wide pale streak. Orbicular stigma smaller than the reniform stigma, both with pale centres and somewhat 
dark circumscriptions. Outer transverse line faint, darkly indicated on veins. A marginal line formed of dark 
lunules. Hindwings impure white with dusky dustings on veins and at margin. A darker brown marginal line.
