have disappeared: immaculata Vrty. denticulata Vrty. always has dentate, deep black marginal bands and irnmacula- 
all the other markings both of <$ and $ are large and striking: from Korla and Ararat.— Verity received 
specimens of the race urumtsiensis from Urumtsi in the Thian-Shan. They are larger than normal with brighter urum t s ien- 
colours and heavier markings. The have the discoidal spot united with the submarginal band by a sis. 
particularly heavy black streak. 
C. viluiensis Men. (Vol. 1, plate 26 f). A variety of this rare species sulphureaflava Shelj. comes from the viluiensis. 
Dzhugdzhuz Mountains. The upperside is sulphur yellow with greenish subapical marks. The underside of the 
forewings yellowish green and inner margin white. - - ab. alba Vrty. is an albino $. The orange coloured areas a lba. 
of normal specimens are white with a tinge of bluish green. The marginal bands show brownish black colouration 
with sparse and small white spots. On the other hand specimens have also been found with these spots so 
enlarged that they form an almost continuous pale band. Base and inner area of wings is grey dusted with 
greenish white scales. The median spot of the hindwings is white. 
C. tunkuna Aust. from Tunkun in the Sajan district resembles viluiensis more closely than hyperborea tunlcuna. 
and can certainly be taken to be a subspecies of one of these species. The forewings of the are sulphur yellow 
and show a very wide, black marginal band which is fairly straight on the inner side. On the costa of the 
hindwings there is a longish “meally spot” tinged with reddish. The marginal band is wide and has a large, 
clearly outlined dentation jutting out in the middle into the area of the wing. The general impression is a 
dusky one through the dark dusting and especially through a streak that extends from the base to the lower 
outer marginal angle. The underside shows no especially characteristic differences from viluiensis. 
C. lada Gr.-Grsh. (7 g) (Vol. 1 , p. 67). Only one variety has become known as oreas Gr.-Grsh. 
white form of the $ with faint orange tinge. 
This is a lada. 
oreas. 
C. hyperborea Gr.-Grsh. (7 g) (Vol. 1, p. 67). Verity describes a form as viluiensoides from the hyperborea. 
Province of Jakutsk, which is very close to viluiensis , so that one feels almost inclined to doubt whether same r^uiensoi- 
^ dcs. 
should be ascribed to hyperborea. 
C. sulitelma Auriv. (Vol. 1, plate 26 f). A number of varieties of this species that occurs in profusion sulitelma. 
in many of its localities has been denominated. Most of these variations are of such immaterial nature that 
they scarcely justify nomination. $ ab. citrina Stgr. has the upperside of the wings a nice lemon yellow and cilrina. 
looks very like ladakensis (7 f). Probably identical with it is joera Rosa, which has a canary yellow upperside. 
— Specimens that have the base of the forewings particularly darkly adumbrated are called obscura Sheld. — obscura. 
ab. holmbomi 0. B.-H. are of pale green colour; only the median spot of the upperside of the hindwings holmbomi. 
is coloured orange and the fringes are a bright rose. The undersides resemble normal specimens, except for 
the inner area of the forewings, which is also green instead of orange. Lule (Lappish March). — rosea Sheld. rosea. 
are SS characterised by a rosy hue on the uppersides of all wings. — (J-ab. suppressa Sheld. have black marginal suppressa. 
bands without traverse white veins. — Sheldon names nigropunctata specimens which have no orange nigropunc- 
centre in the discoidal black spot of the forewings and distincta Sheld. $$ which have the yellow submarginal f . f . J^ a ' 
spots particularly large and clearly outlined. — ochreasuffusa Sheld. are specimens with the lower four sub- ochreasuffu- 
marginal spots of the hindwings merged in the ochre coloured ground colour so that they are indistinct. sa. 
C. chrysotheme Esp. (Vol. 1, plate 28 f). The 1st generation is smaller with less lively colours on the 
upperside. On the underside the green colouring is more intensive and extensive: Skala has named it minor. 
— Verity’s proposal to call the summer generation aestiva is unnecessary, as chrysotheme Esp. is sufficiently 
warranted. — The quite white form of the $ is called alba Vrty. (= alba Bayer, alba Bienert, nom. mid.). — 
$-ab. standfussi Gr.-Grsh. has a reddish hue to the wings, the disc of the forewings is orange, the base of the 
wings dusted with greyish and the antemarginal spots white. The hindwings are grey with faint reddish tinge, 
base and inner margin light sea-green, outer margin greenish yellow. The underside shows a reddish white 
colour. -— jlavescens Vrty. is synonymous with hurleyi Aign.: malmyzhensis Krul. is the same as schugorovi Krul. 
■— albicans Skala are dd 1 with yellow ground colour with an inclination to green, somewhat as in rhamni- $. 
They show little dark powdering and have a dull orange spot in the middle of the hindwings. This seems to 
be a partially albinotic form. — ab. praeclara Sterzl. shows a uniform deep orange colouration on all wings. - 
striata Pieszczek inclines to adumbration in both sexes: black streaks extend into the area of the wings from 
the marginal band. -— In $ ab. obscura Skala the dark marginal band on the forewings extends and inclines to 
suppress the yellow antemarginal spots-: however on the hindwings the pale marginal and antemarginal spots 
stand out more boldly. — hecloides Vrty. is a form of the in which the inner edge of the marginal band 
appears diffuse in an apparent endeavour to form numerous yellow spots, such as is frequently the case in 
hecla. — In $-ab. flavoradiata Pieszczek the marginal band is strikingly traversed by yellow veins. — Around 
Poltava in S. Russia a form of the 2 flies that is like schugorovi Krul., but which is lighter and paler orange. 
The forewings have cuneiform lower yellow antemarginal spots with the points outwards. The spots of the 
hindwings are pale yellow in acuminata Vrty. — In ab. lutea Skala the yellow submarginal spots are increased
