stigma has a black dot in centre. Posterior transverse line is similarly white, edged inwardly by a black 
dentate line. There are 2 black spots before the white subterminal line, one at costa, the other in centre. 
Fringes with black checks. Hindwings like those of speciosa with 2 black-brown undulate bands near margin. 
Wing expanse: 32 mm. N. Saghalin.

A. adducta Herz was omitted from Main Volume. W. Petersen has made a study of the species and adduda. 
states that same is a genuine species and not a form of sincera, as was presumed by Herz. Ground colour 
of forewings is rufous, more or less dusted with whitish grey. Both stigmata, especially the reniform, are 
smaller. The transverse lines are scarcely discernible. The black basal streak is distinct in merely indic¬ 
ated in $. Subterminal line and sagittate marks before same are barely visible or not visible at all. Hind- 
wings uniformly dusky yellow-grey without the grey-white hue of sincera. From Vilui. 
A. tamaiiukii Mats, is like sincera but differs by the dark grey colour, larger and somewhat oblique tamanukii. 
orbicular stigma. The latter is larger than the reniform stigma which has a brownish centre. Costa and 
fringes with reddish tinge. Hindwings with wide black-brown marginal band. antennae serrate with sessile 
fascicles of cilia. Underside dusted with reddish brown. Wing expanse: 38—40 mm. N. Saghalin. 
A. griseola Mats, resembles tamanukii, differing by the longer and narrower formation of wings and griseola. 
paler ground colour. Anterior transverse line distinct, with white inner edge. Orbicular stigma larger but 
extinct, the reniform stigma similarly, especially outwardly. Postmedian line narrower, a distinct black sub¬ 
terminal line. Costa and fringes without the reddish tinge. Hindwings paler, abdomen longer. Wing expanse:

species (12 g) from a typical specimen from Muonio (finnish Lapland). 
A. vega Herz (Vol. 3, p. 59) (12 g) occurs in the Malchan Mountains. The description of forewings in vega. 
Main Volume: “elongate” was an error. It should have read: forewings bluish, ashy grey. It resembles gelida, 
but markings are more diffuse. The transverse lines are certainly not, as was previously stated, only plain 
towards inner margin. They are delicately and not conspicuously dark. The posterior line is much less 
sharply dentate. Both lines have whitish edges on averted sides. The distinct black patch above the median 
nervure is absent. Reniform and claviform stigmata are obscurely marked with brownish centres. 
A. excavata Mats, somewhat resembles vega. Forewings ashy grey with black basal streak. On costa excavata. 
there are conspicuous black-brown marks caused by an enlargement at the commencement of the transverse 
lines. The large orbicular stigma is elliptical on top and has a black circumscription. Reniform stigma more 
obscure, the space between the two is filled with dusky brown almost in the shape of an “X". The trans¬ 
verse lines are delicate, the posterior line has a parallel row of dots on the veins. At subterminal line there 
are 3 dark sagittate marks inwardly on costa, in centre and at anal angle. Hindwing with central and sub¬ 
terminal bands. Wing expanse: 38 mm. N. Saghalin. It appears to me from the illustration and descrip¬ 
tion that this species, subgrisea respectively albuncula are one and the same. 
A. acuminata Mats, is said to resemble tamanukii, differing by the narrower and more pointed fore- acuminata. 
wings. Stigmata somewhat larger, claviform stigma however smaller, but distinctly circumscribed by black. 
The distinct postmedian line has a white outer edge. Wing expanse: 42 mm. N. Saghalin in August. 
A. brunneopicta Mats. Forewings are darker grey-brown than those of the preceding species, with brunneo- 
undulate basal line and a black line that extends from base to postmedian along the submedian fold. Ante- pi da. 
median line is undulate. The oval orbicular stigma is pale brown, elliptical at top, the auriform shaped 
reniform stigma has a rufous centre. Central line indistinct, brownish, posterior transverse line is delicately 
marked and undulate. In place of the subterminal line there are brownish dots which are more distinct 
between veins 4 and 6. Marginal area reddish brown with small black marginal lunules. Hindwings dark 
grey, paler at base and with black-brown discal spot. Wing expanse: 35—36 mm. N. Saghalin. 
A. filipjevi Shelj. (= nigrotecta Corti i. 1.) (12 g). Whilst the author placed this species next to sigma, filipjevi. 
Corti classifies it here. It has the widest wings of any species of this group and is the duskiest. Thorax 
and hindwings sooty black with faint reddish sheen. The transverse lines, especially the posterior, are scarcely 
discernible in the dark ground. They are sharply dentate and have slightly paler edges on averted sides. 
On costa they expand slightly forming whitish spots. The small stigmata have black circumscriptions. No 
subterminal line is visible, however veins in marginal area are somewhat deeper black and terminate at base 
of fringes in a light spot. Hindwings dark grey-brown with heavy black marginal line. From the river Djelinda 
in E. Siberia and from the Sajan district.
