coloured and marked as in rumicis and carbonaria, brownish grey-black sprinkled with black; orbicular stigma 
larger than in rumicis with darker centre and below beyond same a light spot. Hindwings ochreous with wide 
black-brown marginal band with light marginal spot before the anal angle. Corea. 
A. niveosparsa Mats. (1 d) is a very small species reminding one of certain Erastria species. Bore wings niveosparsa. 
dark brown, sprinkled with white and black, all transverse lines fairly suffused or obscured, only indicated 
by small spots; orbicular stigma white with grey-brown centre, outlined in black on both sides, indistinct 
reniform stigma dark grey with black and white markings, space between the two stigmata darkened; marginal 
area white sprinkled with small black spots; a white longish spot on costa anterior to orbicular stigma. Hindwings 
grey, veins darker, head white. Honsho (Kyoto), also mentioned by Draeseke as from Szechuan. 
A. omihsiensis Draes. (1 d) resembles niveosparsa in outline, but is V^t'd larger. Forewings whitish omihsiensis. 
grey, subbasal line only distinct at costa: both transverse lines whitish bordered with black on both sides, 
most distinct on folds; both transverse lines are conjoined in the submedian by a fine curved line; the large 
round orbicular stigma is whitish bordered with grey on basal side and with grey centre, the indistinct reniform 
stigma similarly; the whitish fringes are checked with black between the veins. Hindwings grey-brown with 
faint broad median band and pale yellowish fringes. Omihsien (Province Szechuan). 
A. subornata Leech. —- brunnea Hmps. forewings are browner and less grey. The illustration in Vol. III. brunnea. 
pi. 3 f is a very bad copy according to Leech and quite unrecognisable. The species closely resembles rumicis 
on forewings. Unfortunately we have not been able to obtain a suitable type for a better illustration. 
A. pruinosa Gum. 
A. consanguis Btlr. 
A. Jozana Mats. (1 d) somewhat resembles consanguinis and also phaedriola, differing from same by jozana. 
the more brownish ground colour. Forewings grey-white, marbled with black and brownish; 10 small black 
spots on costa; the small round orbicular stigma has a suffused dark centre and is circumscribed with black, 
the large reniform stigma has dark grey centre and is circumscribed with brown-black; below the median nervure 
a long basal streak, both transverse lines double with whitish between, anal dart-shaped mark narrow. The 
illustration from Matsitmura shows both longitudinal streaks conjoined in discal area by black at submedian 
nervure as in strigosa. Hindwings pale brown-grey, darker at margin with extinct postmedian and white 
fringes. Hokkaido (Japan). June and August. 
A. albistigma Hmps. (1 d) is a very large species from Japan with forewings sprinkled with grey-brown albistigmcc. 
and brightly contrasting white orbicular stigma of somewhat oblique elliptical form; the grey reniform stigma 
is outlined with black at sides and marked with white spots, the double postmedian is filled with white between 
subcostal and upper median and lower median and submedian nervines, the undulate subterminal is white. 
Hindwings light brownish yellow, veins and marginal area brown with indistinct curved postmedian. 
A. rumicis L. — ab. marginata Lambill. corresponds to the virgata forms with dark marginal area. — marginata. 
meridionalis Dannehl (1 d) from the S. Tyrol are more brightly marked summer forms with ochreous tone on meridio- 
hindwings. — suhriana Gillm. closely resembles marginata, but basal area is also adumbrated, discal area on . 
the other hand remaining light. — polonica Pruffer is not grey-black, but uniform dark brown with black polonica. 
shading without the inner marginal white spot. Hindwings dark brown like the forewings with wider marginal 
band. The following is probably synonymous: — priifferi Mast, with darker upperside of forewings without prufferi. 
the inner marginal white spot. — subsp. oriens Strd. (1 d) from Japan and V/. China is much larger and darker oriens. 
than the european name type, whilst the northern african form. — pallida Rothsck. (1 d) is pronouncedly pallida. 
paler, but not as light as the central asiatic — turanica 8t.gr. (I e) of which we are illustrating a cotype of turanica. 
Staudinger ex the collection of Pungeler. According to Oberthur the race from Tunis is said to be somewhat 
darker again than mid-european specimens with less brownish being purer grey with spots and markings on 
paler ground. As against what has just been said under oriens Obertiiur says that specimens from Ta-tsien-lu 
are still paler and more whitish; according to this matters are not very clear; unfortunately I have no specimens 
of this pale nature from W. China at my disposal. 
A. lutea Brem. & Grey — ab. aurantior Strd. has deeper orange yellow hindwings. — leucoptera Btlr. is aurantior. 
not a separate species according to Hampson, but only a form of lutea having more whitish hindwings with 
only faintly yellowish tone. Both forms occur in east Asia.
