specimens: all veins, especially those of the hindwings are scaled and surrounded by black. Base of wings 
heavily powdered with black. Underside of hindwings looks dark yellow green owing to the heavy black scaling. 
Broad yellow scaled streaks appear internervally in the wide and pale margin of the wings. 
C. nebulosa Oberth. (Vol. 1, jdate 25 f). Verity describes a form niveata from the Kuku-Nor district. 
These are very white $$ which seem to form a transition to sifanica, especially the forewings are very similar 
to this species. Based on ample material 0. Bang-Haas declares that this form constitutes a subspecies. 
C. christophi Gr.-Grsh. (Vol. 1, plate 25 g) ab. novosiltzovi Avin. (= simplicissima Avin.) is a 2 from 
Ferghana in which the reddish streak on the forewings is entirely absent. — A further variety of the $ is 
bang-haasi form. nov. from the collection of 0. Bang-Haas. The hindwings are richly scaled with brown. A 
wide streak extends from the base over the disc to nearly the edge of the wings which is somewhat paler than 
the brown of the forewings. 
C. ladakensis Fldr. (Vol. 1. p. 65) (7f). flava Bit. emanates from Laptel, Kumaon and Thibet: they 
are <3$ with yellow uppersides and the forewings have a yellow disc on the underside. 
C. hyale L. (Vol. 1. plate 25 g). Verity names the spring generation vernalis, they are smaller on the 
average and generally paler in colour, being not so richly coloured as the summer form. The third generation 
is called supervacanea Krul. : it is mostly paler than the name type and has a wider black margin: the forewings 
show heavy black dusting on the upperside. The underside is greenish. It was observed in the provinces of 
Wiatka and Kasan. Varieties of the <$ are: sieversoides Vrty. almost unicoloured, canary yellow. Only a 
small inner band is weakly developed at the apex, the median spot is heavy and deep black (whether = apicata 
Tuttl). albescens Metschl. are very pale <$<$, the ground colour of which scarcely differentiates from that 
of the $2. — fulvocoma Krul. are GS from Wiatka with pale golden yellow uppersides. — ab. viridis Mellaerts 
have the ground colour of all wings greenish instead of yellow. ochrocretacea Fritsch have chalky ochre 
coloured ground colour with dull black apical mark. melanina-,^ Vrty. (= melaina Mueck ) are very adum¬ 
brated and of dusky appearance. The marginal band is very wide and clearly outlined without any pale spots 
and stretches to the inner margin. The discoidal spot of the hindwings is quite black, all the veins are scaled 
with black. — gartneri Skala originally described as a form of myrmidone is synonymous with atava Beutti. — 
2 aberrations are: flavoapicalis Metschl with apex heavily dusted with yellow. - ab. canarina Std. is an extreme 
inversa form with buttercup yellow ground colour. — argentea Fritsch is pale silvery white on the forewings, 
hindwings similarly coloured but with grey dusting. The base of the wings lustrous greyish blue. Underside 
of the wings similarly coloured with a bold streak from the base to the median spot. - - pseudohelice Metschl 
is a $ of yellowish white ground colour, the hindwings covered with greyish black except for the anal fold. In 
appearance it reminds one of edusa helice. — ab. argyphea Lowe has the underside of the hindwings completely 
grey white, also the apex of the forewings instead of dark yellow. — rufa Vrty. shows the underside of all wings 
with reddish tinge. mellaertsi Lamb, are specimens smaller than normal, of a nice lemon yellow ground colour, 
both on upper and undersides and the hindwings on the upperside have an orange red spot. — ab. miner Vorbr. 
and pygmaea Lamb, is a dwarf form not larger than a Lycaena. In ab. gloriciana Fritsch the black median 
spot of the forewings is enormously large extending in cuneiform shape towards the apex of the wings: the 
orange spot of the hindwings is also abnormally enlarged. elongata Vorbr. has an enlarged median spot of 
the forewings and besides it is conical anteriorly and posteriorly. — bipupillata Cab. has the spots of the hindwings 
double. flavoradiata Ostli. shows the black margin of the forewings completely traversed by the yellow r scaled 
veins. -- In galvagni Std. a brown spot occurs through the mixing of yellow scales with the black in the 
apex, but without creating sharply outlined yellow spots. - In ab. brevis Crombrugghe the black marginal 
band of the forewings ceases already at the first branch of the media. — $ ab. brabantica Stdr. has a wide 
yellowish-white band in the black band of the forewings, which is interrupted shortly below r the costa, In 
striata-^ Zusanek the yellow^ submarginal spots of the fore wings are so increased in size from the apex to the 
middle of the wings that thereby the black of the submarginal band is almost completely extinguished and the 
veins of the forewings are dusted with black proximally. — In flavofasciata Lamb, the yellow submarginal 
spots merge forming a continuous band in the black marginal band of the wings from the costa to the inner 
margin. — In flavofasciata-crassipunctata le Charles the yellow band continues over into the hindwings and the 
discoidal spot of the forewings is excessively enlarged. — ab. immaculata Der. (= inornatura Der.) differs from 
obsoleta Tutt (Vol. 1, p. 65) in that all the dark markings have disappeared. omnimarginata Hafn. (= schon- 
feldi Metzn.) shows unusually wide marginal bands on the upperside of the hindwings. — ab. opposita Zusanek 
has on the underside of the forewings a row of soft brown spots on the extremities of the veins. — In demarginata 
Nitzsche all the antemarginal spots on the underside of the hindwings are absent. hybr. myrmhyale Meeke 
is said to be a hybrid between hyale x myrmidone. — The following local races and varieties have still to be 
mentioned: uber Vity. a very large form of 45 mm expanse, from the maritime alps: it is very pale with wide 
black bands reminding thereby of alta Stgr. (Vol. 1, pi. 26 a). For the very fine and large summer generation
