larger and sleeker, antennae almost without pectinations, with dense ciliate bristles; frons rough grained, 
no crater. Forewings dark grey-brown with similar stigmata and markings as the preceding species. Differ¬ 
ing however distinctly by the pure white hind wings in which the veins are scarcely darkened at all. Hi¬ 
therto only 1 $ specimen known from Akshehir. 
Ch. capnistis Led. (Vol. 3, p 48, pi. 10 i). The illustration in Main Volume is unsatisfactory both as 
regards shape and colour. It is much too large, wide winged and too grey, the markings are not recognisable. 
We are therefore giving a good illustration (7 1) in which however the outer transverse line might be a shade 
whiter. The species is of paler colouration than multangula, hindwings quite white. 
Ch. hahni Chr. (Vol. 3, p. 54, pi. 12 i). The description in the Main Volume is not quite correct. The 
claviform stigma is not joined to outer line by a black streak. It extends as a fine black streak to the 
inner collateral of the post median line. The illustration is much too pale and yellow, the stigmata should 
he more prominent, the pale transverse line is too dark and the blue line before the margin should be re¬ 
moved. Merv, Askhabad, Arwas, Shahku; Ordubad. 
Ch. calorica Corti (8 a). Resembles hahni closely in superficial resemblance, but is somewhat smaller. 
Thorax is covered with long thin hairy scales, whilst in liahni it has coarse wide scales. Ground colour of 
forewings a very glossy mouse-grey with violet sheen, darker towards margin, less brightly marked than hahni, 
with whitish dusted veins; subterminal sagittate marks are distinct, which are absent in hahni. Hindwings 
darker. The fascicles of cilia on antennae of $ are longer than in hahni. Djarkent, Ili. 
Ch. guberlae Corti (8 a). Forewings glossy, velvety mouse-grey with deep black basal streak, the 
transverse lines partially formed of velvety black spots; orbicular stigma in between two black squares, reni- 
form stigma large, mouse-grey; subterminal line pale, no sagittate marks. Hindwings whitish, dusky at margin 
and along the veins. The $ is a darker blue-grey. Certainly related to capnistis, but differing in the genitalia 
and easily distinguishable by the transverse lines which are not paler. From the southern Urals (Guberla). 
Ch. vicina Corti (7 1) is similarly marked to the following neara, but the transverse lines are less den¬ 
tate; vicina is much smaller and with narrower wings, the hindwings are brownish to brown. The <$ antennae 
show indications of pectinations, whilst in neara the fascicles of cilia join directly on the shaft. Issyk-kul, 
Alexander Mountains, Kuku-Nor. 
Ch. neara Pglr. (7 1) is larger than vicina and with wider wings. Forewings show a warmer brownish 
tone, the transverse lines are somewhat more dentate, otherwise the markings are the same. Hindwings are 
pure white. The genitalia differ considerably. Transcaspia (Merv). 
Ch. juvenis Stgr. (= coelebs Stgr.) (Vol. 3, p. 48, pi. 12 c). The hindwings are not pure white as in 
the closely related capnistis, but they are darkened towards the margin and along the veins. The illustra¬ 
tion in the Main Volume is somewhat too reddish, otherwise it is good. The relatively small reniform stigma 
and a black sagittate mark along the inner margin before the anterior transverse line and extending almost 
to the outer line, are characteristic. A somewhat doubtful species, which perhaps should be classified with 
capnistis. Described from Zeitun. 
Ch. mediorufa Corti ined. (11 d). This apparently should be classified here. Thorax blackish crimson, 
interspersed with whitish hairs. Forewings of coppery red-grey ground colour, densely scaled with black with 
the exception of the median area, transverse lines double, black, interfilled with somewhat paler reddish, simi¬ 
larly the stigmata, which are submerged, but delicately outlined with blackish. The ground between them is 
black. From the inner lower lobe of reniform stigma a blackish shadow-like median line extends to the inner 
margin. The posterior transverse line is boldly dentate. Subterminal line faintly paler, edged inwardly with 
faint sagittate marks. Hindwings uniformly brownish grey with faint diffuse central shade, a somewhat 
darker subterminal and darker marginal line. Type one from Sutchanski-Rudnik in the collection of Corti. 
Ch. tragica Corti ined. (11 d) is very close to the preceding species, but much larger and more robustly 
built, the wings are wider and regularly superdusted with black, so that the reddish ground colour is only 
visible at rubbed patches. The transverse lines are similarly marked as in mediorufa, but they are not double 
and scarcely have paler edges on the averted sides. The posterior line is very regularly sharply dentate. The 
stigmata are not paler than the ground, have fine black circumscriptions, the orbicular stigma is quadrangu¬ 
lar upstanding on an angle, the outer tip almost touches the reniform stigma. Above the ground of the cell, 
is interfilled with black in triangular shape. The large claviform stigma has a black outline. Subterminal 
lines somewhat more distinct, base of fringes paler. Hindwings dark grey-brown and marked as in mediorufa. 
Type one <$ from Irkutsk in the collection of Corti. 
Ch. moerens Stgr. (Vol. 3, p. 48, pi. 12 h). The illustration was a copy and is not natural, as it is 
much too large and pale. We are now giving a better illustration (11 d). 
Ch. secreta Corti ined. (11 d) is similar to moerens, differing anatomically in the formation of the anten¬ 
nae, there being sleek serrate pectinations with fascicles of cilia on the shaft, which are absent in moerens.
