colour otherwise pale yellow-grey, the transverse lines dissolved into dots. Underside almost white with 
heavily blackened velvety outer bands. Syria (Marash). 
D. peperida Limps. (Vol. 3, p. 34, pi. 7 e) and peperida. 
D. xanthiodes Hmps. (Vol. 3, p. 33, pi. 7 c) are classified in this group by Corti. xanthiodes. 
II. Group: Underside of wings without pronounced marginal bands. 
D. pudica Stgr. (Vol. 3, p. 56, pi. 13 f). The illustration is fairly recognisable, only the transverse pudica. 
markings should be less heavily black, the figure on 7 h is better in this respect. — griseola Stgr. the greyer griscola. 
form, which also has much paler hindwings, is now being illustrated 7 h. 
D. despecta B.-H. (7 h) is a larger sleeker species with elongate yellow-grey wings having a faint red- despecta. 
dish tinge. Markings similar to those of clara, but transverse lines are paler and less distinct; irroration heavier 
than in clara ; fringes faintly checked at base. Hindwings whitish, veins and margin faintly dusky. Aksu. 
D. clara Stgr. (Vol. 3, p. 34) (7 h) has, as mentioned in the respective species, no connection with clara. 
celebrata and verecunda, as was assumed in Main Volume. A nice pale, clearly and boldly marked species.

verse lines, the fresh illustration given here (7 i) is better; ignara is a much darker, almost brown species, 
subterminal sagittate marks distinct. From Mongolia. 
D. verecunda Pglr. (Vol. 3, p. 34, pi. 7 e) (7 i) is a genuine species, smaller and with narrower wings verecunda. 
than clara, much paler in its general colouration, pale reddish grey or even purer grey, all transverse stripes 
are absent except for faint indications on costa; before margin there is a band-like very faint grey shade. 
Hindwings pure white. Issyk-kul. — bisigoata Kozh. (7 i) is a darker form with bolder markings and especially bisignata. 
well defined transverse lines with a faint median shade. Ground colour is rather too dark on our illustration. 
D. himalayensis Trti. only recently described, yellowish grey-white, stigmata quite absent, trans- Mmalayen- 
verse lines consisting of blackish conjoined lunules, near the outer a faint median line, which is slightly s i s - 
angulated at end of cell; a black spot basally on costa, at margin a fine dark line, fringes of same colour 
as ground. Hindwings paler than preceding species, devoid of markings, faintly dusky at margin. Underside 
without dark marginal band. From Karakorum (Pashwan). 
D. singularis Stgr. (Vol. 3, p. 34, pi. 12 g) (lOi) certainly belongs here according to the researches of singularis. 
Alpheraky ; the Genus Orbifrons is superfluous. As this rare species, that has hitherto only been sparsely 
caught in Palestine, was not well illustrated in the Main Volume, we are giving a better illustration here. 
Subgenus: Chersotis Bsd. 
Type: Ch. rectangula Schiff. 
Ch. rectangula Schiff. ( = exclamans Ev., subrectangula Stgr.) (Vol. 3, p. 48, pi. 10 i) (8 b). This species rectangula. 
is often difficult to distinguish from multangula owing to superficial resemblance but can certainly be recognised 
by the antennae. In rectangula there are scale-like protuberances outwardly on the antennae, which are absent 
in multangula. rectangula is generally somewhat larger, also more monotonous and redder in shade. — ande- andereggii. 
reggii Bsd. (8 b) is somewhat smaller, the colouration a shade redder, markings clearer and darker. The Alps, 
Pyrenees, Basses Alpes, Crimea, Kamchatka. — acutangula Stgr. (8 b) is as large as the type form, with acutangula. 
somewhat narrower wings. These are darker grey in colouration and more clearly marked, the 3 stigmata have 
a more distinct pale outline. This is the central asiatic form. 
Ch. multangula Hbn. (Vol. 3, p. 48, pi. 10 h) (7 k). The differences from the preceding species are multangula. 
mentioned above. A nice aberration is illustrated (7 1) with darker median area. — dissoluta Stgr. (= tra- dissoluta. 
vunia Schaiv.) are lighter specimens with outstanding black markings and sharper pale transverse lines. It 
occurs everywhere concomitantly, in Switzerland, Italy, Spain and also in Baden, Transylvania etc. Transi¬ 
tion forms are frequent. Corti has given his reasons why he cannot consider travunia, which has been descri¬ 
bed as a constant race from Herzegovina, as distinct. — subdissoluta Wgnr. ( Corti i. 1.) (8 a) is an interesting subdissolu- 
race from Inner Anatolia (Akshehir) which occurs in the 2nd half of June and differs by having strikingly ta ' 
white hindwings, much paler than any other known multangula race; the underside is glossy blue-black, the 
arched stripe is much more distinct; it approaches both neara and capnistis. 
Ch. gratissima Corti (11 c). As nothing is yet known in regard to the systematic position of this gratissima. 
peculiar species, it is meanwhile being placed here on account of the resemblance in the markings. It is
