are sharp and black, the red area around the black anal spots united into an orange band. The smaller 



amurensis. and above less bright form from the North has been separated by Ruhl-Heyne as ab. amurensis. The larger 



southern specimens, occurring from Shanghai or there abouts southward and resembling the Indian form, 



hellotia. have long been made known as hellotia J/cm. (^ praxiteles i^Wr.): some of the summer-specimens from 



l)an-}iasius. the North are similar to it. — parrhasius F. {= dipora Moore, amj-ntas Koll.) is the Indian form, which 



extends into Kashmir; its underside is uniformly white-grey, the anal orange-band broad, the black margin 



of the upperside of the o also broad, and the upperside of the $ is very strongly blue-grey. — Many 



of these forms have been and some are being considered as distinct species. Among nearly all occur 



caeca, individual aberrations; the black spots of the underside for instance may be absent — ab. caeca Aign. — 



depuncta. or but represented by vestiges (these generally in cell 2) : ab. depuncta Hirschke. The anal red of the 



hindwing may also be feebly repeated in the anal angle of the forewing. etc. — Egg very small, not larger 



than that of Zizera minima, light blue-green, with whitish reticulation. Larva green, in the centre and 



on the sides of the back with dark longitudinal lines, head and spiracles blackish, on segment 10 a gland 



surrounded b}- short ciliae, which attracts the ants: in Juh" and the autumn on species of trefoil; carni- 



verous. Pupa rounded, with the head anteriorly truncate; always fastened on the midrib of a leaf by 



a thin belt and the cremaster, very similar to a rolled in leaflet of trefoil, green, with lighter wing-cases, 



which have whitish veins. It is not known to me whether also the hibernating pupae are always green. 



The butterflies of the first broad (polysperchon) in April and May, those of the second from Juh' onwards, 



almost everywhere, but in many places but singlj'. The}- have a somewhat flapping and rather weak 



flight and are found especially at the sides of main-roads and on roads between fields, settling always 



with the wings half open and not often rising high above the ground. 



fischen. E. fischeri Ev. (78 b, c). Above both sexes black-brown, the q with a chain of very thin blue-white 



dashes before the margin of the hindwing. Beneath very similar to the preceding, but the ground-colour 

 darker grey, the dots more distinct and coarser, and the orange anal band of the hindwing not so promin- 

 ent. — From the Ural throughout Siberia to the Pacific, in Corea and on Askold, in June and again 

 in August; mostly- singly. 



potanini. E. potanini Alph. (= umbriel Doh.) (78 b). Above uniformly black-brown; beneath similar to 



argiades, but the black-brown spots more distinct, bordered M'ith white .and somewhat differently arranged; 

 before the margin a dark band-like shadow. — In the interior of China, southward across Yunnan far into 

 eastern India. On Palearctic territorj- obtained in June. 



davidi. E. davidi Pouj. (78 b). Above black-brown, the $ with a row of bluish white ocelli before the 



margin of the hindwing. Beneath almost white, with a feeble yellowish grey tint, without distinct orange 

 band in the anal area of the hindwing; the black dots distinct, but rather irregularlj- arranged. — West 

 China, apparently rare (Leech). 



filicaudis. E. filicaudis Pryer (78 b). Similar to the preceding, but beneath darker grey, the black spots 



heavier and more strongly coming through above, before the anal area of the hindwing beneath distinct 

 orange colouration. — In Northern and Western China, in the mountains, in May and June, not rare. 



ion. E. ion Leech (78 b). Above very similar to fischeri, but the hindwing beneath is darker grey, 



with brownish bands, without distinct deep black dots and without any orange before the margin. — 

 In West China, in June and July, at 5000—8500 ft. 



zuthus. E. zuthus Leech (78 b). Above similar to fischeri, but the fringes of the forewing darker and 



somewhat chequered, the hindwing with a row of heavy, black, pale-bordered dots before the margin. 

 L^nderside grey-brown, with numerous blackish ocelli; before the anal angle a very little orange scaling. — 

 In West China, in July and August at 5000—8500 ft. 



arcana. E. arcana Leech (78 c). Larger than the previous, the ? similar to the ? of PoUjomm. baeticus. 



above black-brown, the base of both wings shaded with blue; the hindwing has before the outer margin 

 a row of yellowish ocelli with heavy black centres. The underside with pale-bordered lines composed of 

 small brownish spots and with a few dark dots. — Central China, found in June and September.

Although this genus with its multitude of species is widely distributed over the globe, its main 

 development obtains in the Plaearctic Eegion, whence we enumerate here more than 200 forms. The
