D. jacobsoni Kozh. has been overlooked. Ground colour of forewings rosy whitish, peppered with black, 
with black and very sharply distinct markings. Fringes pale with dark striations. Hindwings pale with a wide 
dark outer band. Underside pale, glossy with dark margin. Wing expanse: 35—40 mm. Transcaspia (Surnbar; 
Kisil Art). It differs from the similar umbrifera Alph. (Vol. 3, p. 56, pi. 13 f) by the paler ground colour, more 
diffuse postmedian, but more distinct subterminal line; on hindwings marginal band is more distinctly outlined. 
D. assimilata Kozh. resembles clara 8t.gr. (Vol. 3, p. 34; Suppl. Vol. 3. p. 59), differing by the markings 
and the size. Colour is pale ashen grey, peppered with black. Stigmata are faint, as in clara. Both transverse 
lines are more widely separated from one another on costa. Subterminal line distinct, wide and boldly dentate. 
Central shade in the form of a square on costa, wider than in clara. The central area is only half as wide at 
inner margin as in its upper half. The posterior transverse line is only very faintly excurved. Hindwings dark, 
paler towards base with almost white fringes. Wing expanse: 32 mm. Caucasus (Arash). 
D. armeniaca Kozh. is also like clara, but considerably smaller and of ashen grey colour densely speckled 
with black. Markings are only poorly developed. Stigmata practically absent, transverse lines however are 
present. The black subterminal line is somewhat diffuse and with big dentations. Fringes pure white. Hind¬ 
wings somewhat dusky from margin to centre. Underside whitish grey with tips of fore wings blackened. An¬ 
tennae of 8 with short and fine cilia. Wing expanse: 34 mm. armeniaca differs from the also somewhat similar 
celebrata Alph. by the more distinct subterminal line and from assimilata by the much wider central area. From 
Armenia (Migry). Described from one specimen. 
0. nigrolineata Kozh. (pi. 25 i) closely resembles the squalorum group. Ground colour grey-brown, be¬ 
strewn with black. The black markings are well developed, the postmedian is markedly displaced inwards, so 
that the outer area is very wide and occupies nearly half the wing. In this way great similarity to squalidior 
is created. Outer area is dark, cuneiform marks on subtermina-l line are only faintly indicated. Hindwings 
dark in $, pale in disc in Wing expanse: 32—35 mm. N. Persia (Shahkuh). 
D. eremicola Stfs. (Vol. 3, p. 34, pi. 12 f; Suppl. Vol. 3, p. 57). — nigrolineata Cti. (Suppl. Vol. 3, p. 57) 
should not be mistaken for the preceding genuine species and should be renamed — dubiosa f. n., as Dr. Corti 
only gave his name in 1933, whilst the preceding species was denominated in 1930. 
D. squalorum Ev. (Vol. 3, p. 49, pi. 10 i, k; Suppl. Vol. 3, p. 57). crimaea Kozh. denoted as a form 
by Dr. Corti, is a genuine species according to Kozhantschikov, and is closer to valesiaca than to squalorum, 
but differs from both in the genitalia. Generally the orbicular stigma is smaller than in the other two species, 
the colouration has a yellowish tinge and dark or brown shades are quite absent. The large reniform stigma 
is elliptical outwardly. The distance between the postmedian and reniform stigma is always greater than the 
width of the latter. Discal and marginal areas are about equally wide. Subterminal line has a white inner edge. 
Hindwings as in valesiaca. The species also occurs in the Kara-dagh. 
D. inexpectata W. Kozh. (Suppl. Vol. 3, p. 57) was introduced as a form of valesiaca , but according to 
Kozhantschikov it is a genuine species, the genitalia of the two species showing considerable divergences. 
Forewings pale to dark grey-brown, those of the $ being constantly distinctly darker. All transverse lines are 
deep black, the dark central shade is intersected in the middle. Subterminal line has a few black sagittate marks 
inwardly. Orbicular and reniform stigmata are not large, round. Claviform stigma with sharp black circum¬ 
scription, but very small. Hindwings of grey-white, of $ dark grey with dusky veins and margin. Minus- 
sinsk, also reported from the Altai. 
D. venosa Kozh. (Suppl. Vol. 3, p. 58). This was also enumerated as a valesiaca form, it is however a 
genuine species and it was a mistake to state “Corti ined. ". It closely resembles the forms of the squalorum 
group and also tyrannus, hut it can be easily differentiated bv the pale colour of the hindwings of <$ (white). 
Markings as in squalorum , but more distinct and with white outline, in squalorum they are simply dark. Sub- 
terminal cuneiform marks are more bold, veins distinctly prominent and dark. Wing contour rather more 
protracted and pointed than in any of the other species. Pamir and Semiretje, not from Sarepta. 
D. melarsuroides Kozh. (Suppl. Vol. 3, p. 58) is a genuine species with different genitalia. It occurs in 
Turkestan and W. Bokhara. 
D. griseotincta Wgnr. (Suppl. Vol. 3, p. 58) is also not a form of valesiaca, but according to Bourses 
a genuine species. Whether brunneotincta should lie classified with it, is not certain. 
D. tyrannus 0. R.-H . (Suppl. Vol. 3, p. 58) is an entirely separate species from celebrata. Alph. and readily 
distinguished. According to Ko zhantschiko v, the latter does not belong among the Dichagyris, but to the 
Subgenus Ochropleura. The most important and characteristic difference is that in celebrata, the two upper 
stigmata are entirely absent, whilst in tyrannus they are present and between them there is a distinct and bold 
black quadrate mark. — striatus Kozh. is a form from N. Persia (Shahrud), which is marked with bold and 
well developed longitudinal streaks.
