OLIGIA. By Dr. M. Draudt. 
unicolor. — unicolor Tutt is devoid of markings, unicolonred dark reddish brown, often coppery to sooty black. The 
victiuncula. black oblique streak is absent, differing thereby from the dark versicolor forms. — - victiuncula Heydem. belongs 
to the dusky unicolor, but has still a deep black angulated central band to inner margin, as in the bicoloria form. 
grisescens. —- grisescens Heydem. is monotonous grey-brown, basal and discal areas somewhat darker, with brown irrorations 
and with the deep black oblique streak. Stigmata with pale grey-yellow surrounds, the grey-brown postmedian 
band is especially pale and is intertilled with white above the inner margin. It occurs as a race on the Lebanon, 
but is also found as a form in central Italy. Wing expanse: 20.5—23.3 mm and thus the smallest species. It 
is common everywhere in Europe and extends southwards as far as Sicily. 
albiluna. 0. fasciuncula Haw. (Vol. 3, p. 172, pi. 40 k). —- albilutia Kozh. Whether this is actually a form of fasci- 
uncula is questionable, as hitherto the latter is only known to occur in western Europe; albiluna only differs 
by a golden sheen on the brown forewings and an outstandingly white crescentiform spot in place of reniform 
stigma. From around Minussinsk. —- erratricula Rmbr. (nec Him.) mentioned in Main Volume as synonymous, 
grandis. is named by Turner: •—- grandis, as according to the illustration it is more than twice as large as typical fasci¬ 
uncula. From Andalusia. 
leuco- 0. leuconephra Humps. (Vol. 3, p. 174, pi. 42 a). The illustration is too much reduced in size, the wing 
nephra. expanse is almost 20 mm. It is uncertain whether the species should be classified here, it has apparently con¬ 
siderable resemblance to the form albiluna of the preceding species. 
iaroulti. 0. faroulti Rothsch. (= powelli Obth.) (19 i) is a grey species, that is related to literosa Haw. (Vol. 3, 
p. 172, pi. 40 1c) but without the red hue. However it must not be confused with subarcta. The central line 
and posterior transverse line are differently shaped, they are not so steeply oblique and do not converge in 
a rectangle on inner margr According to the details given by Rothschild, it is deemed to be a genuine species 
and Heydemann’s investijcations confirm this. Algeria (Guelt es Stel).

minor. O. bicoloria Vill. (Vol. 3, p. 173, pi. 401). — minor Cabeau and —- mimuscula Cabeau are superfluous 
minuscula. names for small specimens in the colouration of rufuncula. —- reisseri Schaw. is a striking variety from Corsica. 
Ground colour of forewings grey-brown with darker brown central area, which is edged on both sides by double 
lines with white interfilling. Orbicular stigma with pale surround; reniform white, appearing larger than it is 
actually owing to a white costal spot immediately above. The faint subterminal line is whitish, fringes checked. 
Hindwings darker grey than in type. HeVdemann states that it is similar to the reticulata forms. I have a 
specimen very like the original illustration of the author from East Prussia (Rauschen). 
rnfata. 0. rufata Kurd, resembles fasciuncula. Forewings yellow-red, the central area barely darker, rather 
paler towards inner margin. The white crescent posterior to the outer transverse line is absent. Reniform stigma 
pale yellow, other markings as in fasciuncula. Hindwings pale brown, 2 parallel lines before margin, margin 
itself dusky. Fringes of forewings fuscous, those of hindwings paler. Wing expanse: 23 mm. Ussuri (Narwa 
Island). 
lignea. 0* lignea Trti. is a small, quite monotonous brown species, devoid of any markings on forewings except 
perhaps for vestiges of the somewhat darker commencements of the two transverse lines on the costa. These 
seem to have a paler edge on averted sides, but the transverse lines themselves are not visible. Hindwings 
monotonous dusky brown inclusive of the fringes, anterior to which there’is an extremely fine black line. Head 
and collar somewhat paler and more yellowish than thorax, which is of the same colour as the forewings. Ab¬ 
domen dark grey. Wing expanse: 21 mm. From a $ from Ain Mara (Cyrenaica), in October. 
kara- 0. karafutonis Mats, resembles a P. secalis, but according to the assurance of the author it is an Oligia. 
/atoms. Forewings brown, darker markings diffuse. The undulate anterior transverse line has somewhat paler inner 
edge, boldy excurved at submedian, central line is wide, darkened at lower angle of cell. Postmeclian with 
short dentations and narrow grey inner edge, outwardly with black dots on veins. Subterminal line pale grey. 
The round orbicular stigma is elliptical above and below with fine white surround. The elongate reniform stigma 
similarly. The small claviform stigma is rather darker than the ground colour. Hindwings dark grey. Wing 
expanse: 30—34 mm. N. Saghalin, in August. 
O. captiuncula Tr. (Vol. 3, p. 174, pi. 41 b). According to Heydemann the name for this species should 
minima, be: —- minima Haw. (1803) and this name deleted under Petit. arcuosa. Recently Warnecke has gone carefully 
into the distribution of this small species and seeing that it is absent from the arctic North and the high alpine 
territories, he questions the thesis established elsewhere that this species is a glacial relic i. e. a boreo-alpine 
species. To be added to the localities mentioned in the Main Volume are: Spain (Sierra de Alfacar), the Pyrenees, 
capti- bavarian Alps, Moravia, Sudetes, Swabian Alps, Vosges, Jena (!), Bulgaria, — captiunculoides Strd. has a red 
unciduidcs. p 0S tmedian area, without any trace of white posterior to postmedian line. —- albosuffusana Strd. has ante and
