erior one irregularly dentate, forming a bold arc round the reniform stigma, touching the lower angle of same 
and then extending almost vertically in 3 small dentations to inner margin. Stigmata white with fine black 
surrounds and brown centres, the reniform stigma is almost rectangular. Marginal area pale brown with pale 
grey dusted veins. Subterminal line very irregularly dentate, parallel to margin and with grey inner edge. 
Bold black triangular marks along margin. Fringes outwardly with checks. Hindwings whitish, peppered 
with grey-brown towards margin, with brownish marginal line and whitish fringes. Palestine and Syria. 
18. Genus: ITloclilacna Led. 
U. hirta Hbn. (Vol. 3, p. 119, pi. 29 d). The illustration is rather clumsy and colours too dark. We 
are giving a better illustration here (16 1), also of the wingless 
19. Genus: 8>er(liisa Wkr. 
D. sareptana Alph. (Vol. 3, p. 119, pi. 29 e). The illustration was a copy from Hampson, which does 
not truly represent this species, that is very like lederi. We are giving a fresh picture here (16 1). During the 
last years this species has been captured in quantities by Fritz Wagner at Akshehir, where it comes to light 
at night at end of September/October. The $$ fly at dusk, the <$<$ only at dawn. It is subject to great 
variations. The colouration of forewings varies from yellowish or pale reddish sandy to bold deep fuscous. - 
rubellina Wejnr. is a red form, somewhat of the shade of Antitype argillaceago. The distinctness of the markings 
also varies as in lederi. The dark thorax is not so characteristic, as stated in Main Volume, as the constricted 
orbicular stigma, the lower half of which is situate below the mediana. 
D. trimacula Schiff. (Vol. 3, p. 119, pi. 29 e). This is rather a difficult species, it seems to embrace 
two species, which are not easily distinguishable, trimacula is larger on the average and is more robustly built 
with darker grey-brown hindwings. The dark undulate marginal line, which is absent, according to Zerny, 
seems nevertheless to occur equally frequently in both species, if I may judge from the large number of speci¬ 
mens before me. The genitalia differ from those of ramburi. trimacula is exceedingly variable. The forms 
enumerated in the Main Volume probably all refer to trimacula , excepting gruneri, which should be placed 
to ramburi, unless it should prove to be a genuine species. According to Culot the type is the yellowish or 
reddish blue-grey form with the blackish grey patch between the stigmata. — tersina Stgr. is ashy grey with 
2 black patches before the orbicular and reniform stigmata (16 1). — dentimaeula Hbn. (17 a) is dark grey-black, 
the orbicular stigma has a single cuneiform projection below the mediana, whilst below reniform stigma there 
are 2 such projections. — hispana Bsd. (= meridionalis Calb.) is similarly marked, but paler lilac grey. - 
ruscinonensis Obth. (17 a) also similarly marked but much paler, especially hindwings. — cinerascens Obtk. is 
quite pale yellowish grey, whilst — unicolor Hup. (17 a) is more reddish brown, both completely devoid of 
markings. — alba Fdz. (17 a) is a pure white form with markings merely indicated and dark hindwings. - 
culoti Ragusa is a deep red form, quite unicoloured and almost devoid of markings. Navarra. Probably the 
same as the subsequent teriolensis, which would then become a synonym. teriolensis Hartig (17 a) is such 
a rich dee]) red-brown that the black markings almost merge in ground colour. This is the most extreme of 
the red forms. South Tyrol, but I also have a specimen from Chodau (Bohemia). — griseoviolacea Wgnr. is 
a peculiar violet-grey with reddish fringes, markings although only indicated as in the usual red forms, 
classified as glaucina. S. Dalmatia. — lilascens Schaw. is probably very like the former, ground colour a nice 
pale grey-lilac, stigmata and veins reddish, fringes of forewings rufous. Generally also there are interspersions 
of rufous scales, especially towards base. Hindwings grey with whitish grey fringes. Albarracin. — flavosignata 
Trti. is a form of the above mentioned rufous glaucina, which has stigmata finely but definitely outlined by 
yellow. From the Apennines of Modena, also from around Como. 
D. ramburi Zerny (= hispana Rbr. nec Bsd.) (17 a). This is the second species, rather smaller and more 
daintily built, with paler and purer white hindwings and different genitalia. To be classified here are: - elvira 
Schaw. with pale ochreous yellow, reddish dusted forewings, orbicular and reniform stigmata with red sur¬ 
rounds, reddish fringes and a row of red dots before margin, anterior to which there is a rufous transverse 
line. Hindwings pale yellowish white with rosy fringes. Albarracin. — osseata Culot (17 b) is a pale yellow 
form with small brownish patches before and beyond the orbicular stigma. — gruneri Bsd. (= albida Obth.) 
(17 b) is pure white with 2 brown cell spots. — rubrescens Culot is almost devoid of markings and a pale cin¬ 
namon brown form. All these forms are found especially in N. Africa (Algeria and Tunisia). 
D. haemapasta Hmps. Thorax fulvous, abdomen inclined to buff. Forewings yellow-white, dusted 
with fulvous, bright red in basal area with a dark streak along inner margin. The blackish antemedian is 
faintly undulate, the cell deep red between and beyond the stigmata. The stigmata yellow-white with red 
centres and laterally edged by black, both of the same shape as in trimacula i. e. extending below the cell. 
The black posterior transverse line somewhat dentate. The white subterminal line has a deep red inner edge
