S. maculifera Mats. (18 h). Forewings grey-brown, paler above mediana in costal half, with dark trans- maculifera. 
verse lines. The mediana is widely velvety black-brown, conjoined with orbicular and reniform stigmata, which 
are of the same shade. The former is round, the latter triangular, both finely edged by yellowish. The undulate 
transverse lines are only visible below mediana, the posterior line has yellowish outer edge. Subterminal line 
is undulate, yellowish with outer black-brown shade forming spots in cellules 3—5. Hindwings grey-brown. 
Wing expanse: 36—39 mm. Honsho (Japan). The species closely resembles Blepharidia costalis Btlr. (Vol. 3, 
p. 141, pi. 34 f) and it is impossible to judge from the rather rough copy of HamFson, whether it is not identical. 
51. Genus: Dasysteriiiim Stgr. 
D. lea Pglr. (Vol. 3, p. 142). This was not illustrated in Main Volume and an illustration is now being lea. 
given (18 h). 
D. colluta Pglr. i. 1. (?) (18 h) is very like juditha (Vol. 3, p. 142, pi. 34 i) but paler, greyer, markings collula. 
sparser and less distinct, the median area wider and not so dark, stigmata barely indicated. Askhabad. 
D. variabile Stertz is closest to bacheri Pglr. (Vol. 3, p. 143, pi. 34 i). Forewings impure ashy grey or variabile. 
reddish brown, paler in $, inclined to impure whitish grey, coarsely and densely scaled. Fringes faintly checked. 
Transverse lines blackish, dentate, the discal area between same faintly darker or unicolourous, narrower in 
lower half. Stigmata fairly large, roundish, pale but indistinct. Hindwings yellowish white with thin black 
marginal line and fainter central line that does not extend to costa. Antennae of $ with shorter pectinations 
than bacheri. Wing expanse: 34 mm. Algeria (Guelt es Stel). 
D. faroulti Rothsch. seems somewhat similar. Thorax and forewings cinnamon-grey, orbicular stigma faroulii. 
punctiform. Large reniform stigma white with brown inner edge. Transverse lines dark cinnamon-brown, the 
anterior section with 3 angulations, the posterior part boldly undulate extending obliquely inwards. Both 
lines edged with white on averted sides. Subterminal line white. Fringes with whitish checks. Hindwings impure 
whitish grey, whiter towards margin with delicate brown marginal line. Wing expanse: 44 mm. Algeria (El 
Messrane). 
D. anceps Stgr. (Vol. 3, p. 143). We are now giving an illustration of this species, that looks just like anceps. 
Antitype rufocincta mucida (18 i). 
D. glaux Pglr. i. 1. ( ?) (18 i) resembles D. tibetanum (Vol. 3, p. 143, pi. 35 a) but has narrower wings glaux. 
with more oblique outer margin. Forewings slate-grey, the lines and stigmata only apparent through an inter- 
spersion of ochreous yellow. Fringes mixed with ochreous brownish. Hindwings dark grey-brown with pale 
yellow fringes. Central Asia (Aksu; Lob-nor). 
52. Genus: Dasythorax Stgr. 
D. rofroui Rothsch. It is not quite certain whether this should be classified here. It has cinnamon-brown roiroui. 
thorax and forewings, the latter peppered with black and with incomplete anterior transverse line that extends 
obliquely outwards to vein 2. The posterior line is black, curved and dentate. Orbicular stigma with black 
surround and centre, the large reniform stigma whitish. Subterminal area boldly peppered with black. Hind¬ 
wings milky white. Wing expanse: 34 mm. Messer in Algeria, in September, based on a single $. 
D. hirsute Stgr. (Vol. 3, p. 143, pi. 35 b). The illustration was not good, we are giving a better one here hirsuta. 
(18 i). This very rare species also occurs in the Tyrol and according to Bottrsin it is found in France (Bessee- 
sur-Durance) in the Hautes Alpes at an altitude of 1000 m. 
D. rasilis Pglr. (Vol. 3, p. 143, pi. 35 b) can also scarcely be recognised from the illustration in Main rasilis. 
Volume and a better picture is given here (18 i). 
D. draudti Osth. (18 i) is possibly a larger more westerly local race of glebicolor Ersch. (Vol. 3, p. 143, draudti. 
pi. 35 b). It is much larger, less olive, more grey-brown with a yellowish, reddish or greenish hue. Transverse 
lines more boldly dentate. Orbicular stigma absent, reniform stigma with only faintly darker centre or uni¬ 
coloured. Hindwings uniform blackish grey. Taurus (Marash). According to Osthelder's views possibly also 
a form of the red Autophila libanotica Stgr., which with Autophila subjusca Clir. would also probably have been 
better classified with the Dasythorax. It would seem a difficult task to draw a definite distinctive line between 
these so closely related Genera. In my opinion the species is really very similar to depressa Pglr. described as 
a Spintherops and it is questionable whether they are not identical. The latter is from Askhabad. Description 
and illustration seem to tally exactly, only depressa is said to be a more ashen grey.
