Z. aricia Gr.-Grsh. from Szechuan resembling prosecusa Ersch. (Voi. 1, p. 296) also in the size. Wings 
are brown-black on upperside, a blue sheen at base and in disc. Fringes are dull brown. The underside pale 
brown. Submarginal ocelli very light, other spots and eyespots small, brown-black. No basal eyespots. 
only 22 mm expanse. 
Z. gisela Pung. (Vol. 1, p. 296). Types are now illustrated on pi. 16 b. 
Z. draeseckei Schawerda is closest to gisela Pung. (16 b) (Vol. 1, p. 296). It is also related closely to 
prosecusa Ersch. (Vol. 1, p. 296). Size is like gisela-, underside brown with diffuse marginal striations. Blue 
of upperside is glossy like that of L. orion L. The 2 mm wide black margin is very striking for this small 
insect, it transfuses into the blue without any harsh outline. In certain light the entire outer %rd of the 
forewing is dark. Outer margin of forewing is straight as in gisela. Tn front of the outer margin of hindwing 
there are no perceptible dots on the upperside. Fringes are dark grey-brown, somewhat darker than the pale 
brown of gisela. Ocelli are quite well developed, with white borders like in Lyc. semiargus but somewhat 
smaller. The arc of ocelli of forewings is more extended than in semiargus. Basal eyespots are absent on 
forewings, there are 2 on hindwings. There are 2 rows of quite pale marginal striations towards the border on 
both wings besides the white edged streak at close of cell on the underside of both wings and the 2 arcs of 
ocelli. No blue scaling at base of wings. The species has an expanse of 21—24 mm and occurs at Wasseku, 
Kwanshien in Szechuan. 
27. Genus: Cliiladcs Mr. 
C. troehylus Err. (Vol. 1. p. 297, pi. 77 k). Only few of the usual aberrations have been observed: ab. 
caeca has the entire arc of eyespots and occasionally also the discoidal and marginal lunules extinct. —ab. subtus- 
obsoleta Graves from Gezirah in Egypt has the black spots and markings on the underside of all wings entirely 
or chiefly extinct. — Similarly from Gezirah and Maadie in Egypt we have ab. mandersi Graves in which the 
submarginal band is reduced to a faint, scarcely perceptible orange-red spot. — From the boundary of the 
palaearctic region around the reservoir at Assouan in Egypt, Hayward describes the ab. albolunuiata which 
has the discoidal lunule on upper and undersides of hindwings coloured white. — The variation grisea described 
by Aigner is smaller than the name type form, grey-brown inclining more to grey, with pale grey almost white 
underside and appears to occur in the island of Cyprus as a race. 
C. yunnanensis Watkins from Yungchang in N. W. Yunnan at an altitude of 5500 ft. occurring in May. 
It is therefore only a boundary form and has not yet been found on genuine palaearctic territory. The only 
known reminds one of a small Euchrysops ( Catochrysops ) pandava Horsf. (Vol. 1, p. 292, illustrated in Vol. 9, 
pi. 153 k) with its black-brown colouration and faint bronze green sheen. The fore wings show at base and the 
entire hindwings with the exception of the margin, pale blue metallic glossy scales. The black discoidal 
lunule of the forewings has a faint light edge. On hindwings in cellules 1—3 there are also black marginal 
spots without any admixture of orange. Tails are scarcely perceptible. On the underside the only known 
which is unfortunately considerably damaged, resembles a pandava of the rainy season. 
28. Genus: Everes Hbn. 
E. argiades Pall. (Vol. 1, p. 297, pi. 78 a). Tutt has created innumerable little forms of this species 
in the same way as of those species which he has treated in his extensive researches, and whatever one may 
think of the matter, these forms should be mentioned. They are chiefly variations in colouration. — ab. 
ardescens Tutt, of pale grey-blue ground colour ab. purpurascens Tutt ground colour purple-blue. — ab. 
ardescens-marginata Tutt and purpurascens-marginata Tutt the same as the above but with wider dark margin 
than the name type form. — ab. bergstraesseri Tutt is a I’are $ aberration of the spring form with blue colour 
and dark margin. Marginal spots in hindwings are surrounded by pale blue crescents. — ab. $ jodina Aigner 
resembles the former closely but the marginal spots of hindwings are enclosed by orange-brown crescents. —- 
ab. ardescens-fulva Tutt the pale blue-grey crescents in marginal spots on hindwings as in ardescens but orange- 
yellow in this case. — ab. ardescens-restricta Tutt has the delicate grey-blue restricted to the base of the wings, 
also the orange coloured lunules are absent, whilst in ardescens-completa Tutt the lunules are a nice orange 
colour. — ab. pallida-fulva Tutt is pale brown with blue sheen and orange coloured lunules, whilst ab. pallida 
Tutt is without these orange lunules and simply pale brown without the blue sheen. — ab. coerulescens Tutt 
is brown, forewings with blue scales as far as behind the disc and on the hindwings as far as the outer margin. 
In exceptionally richly marked specimens an almost parallel blue band is created to the black outer margin. — 
If there are orange coloured lunules in the marginal spots then we have ab. coerulescens-fuiva Tutt. — coeralescens- 
restricta Tutt has blue scales only at base of wings, however when with orange coloured lunules we have
