 markings, is also of a greyish colour. Scandinavia, North Russia, as far as Central Asia. — viluiensis Miii. viluiensis. 

 (= grisescens Christ. ), from the Vilui river in Siberia and from the mountains of Werchojansk, north of 

 Jakutsk, is on both sides bright grey, not yellow; the whitish median band of the underside of the hindwing 

 shines through above and is shaded with grey towards the base; the base of the hindwing beneath washed 

 with green. — caeca SI;/)-., from the Namangan Mts., is a small form without a trace of ocelli, so that it is caeca.

 schatka, and is without ocelli on both sides, like the American ochracca, but instead of being pale yellowish 

 brown, like the latter, is jiale grey above; on the underside the hindwing is grey, the forewing ochre- 

 yellow with a grey margin. — Across the Behring Sea, in Alaska, the species is represented by the closely 

 allied form kodiak Edir. — The most western old-world form is scotica Stgr., which above has a dull grey scotica. 

 ground-colour and dark edges, and beneath is without ocelli; from Ireland and Scotland. — subcaecata subcaecata. 

 Biihl, from the higher Altai, is an intermediate form, closely allied to ochrac.ea from Colorado; it is darker 

 and larger than caeca, but paler than «.s/.s-; single specimens show vestiges of ocelli. — rhodopensis F.lic is rluniofw/isis. 

 a form from the Danubian countries, closely allied to isis, but yellowish brown on the upperside and rarel}' 

 darker in the cf . Of the ocelli on the underside only the pupil of the apical one and sometimes of one of 

 the eyes on the hindwing shines through above. But on the underside of the hindwing this form mostly exhibits 

 a complete row of ocelli, while in an otherwise closely related form, occupata Ii'eh., they are entirely absent; occupata. 

 the latter form occurs in Bosnia and Herzegovina. — Larva pale green, covered with minute dot-like warts, 

 with a globular green head and yellow mouth, dark light-edged dorsal line, whitish subdorsal lines and pale 

 yellow lateral stripe; anal claspers and anal fork rosy red. From September until May on rushes and reeds, 

 such as Carex, Rhynchospora, Festuca, etc. Pupa pale green, abdomen whitish. — The Inittertlies are on 

 the wing in June and July, singly, and on most thght-places not common. Sometimes quite fresh specimens 

 are found in places where no single individual had been met with before in spite of decades of ardent 

 collecting, and from where the species again disappeared for a long time. The flight-places are usually peat- 

 bogs and meadows flooded from time to time, according to Rl'hl, especially such on which Eriophorum grows. 



C. sinica Alph. {= tydeus Leech) (48 h) is doubtless very closely allied to tiphon and might perhaps sinica. 

 be better united with it. Upperside exactly like that of the njinotypical tiphon, but with long bluish white 

 fringes (the latter are yellowish white in tiphoii). Underside of the hindwing mouse-grey with few unequal 

 ocelli; from the apex of the cell a longish white oblique smear runs in the direction of the middle of the 

 distal margin, which, however, it does not reach. — Common in Tibet, in Juh and August, up to 10000 feet. 



C. semenovi Alph. (48 i). One of the smallest forms, dull ochre-yellow above in the cf and dirt}' scmenovi. 

 white in the ?. On the underside of the hindwing a number of vei'y conspicuous white spots, which shine 

 through above. — In Tibet and Western China, in July and August. The butterflies are very common in 

 their flight-places, and in Central Asia are found as far up as 10000 feet. According to Leech they vary 

 very little, but ?? occur which are dark on the upperside like the cf cf. 



C. sunbecca Ei\ (48 h, i). Above, both sexes a dull milky white colour, through which the pattern sunhecca. 

 of the underside shines; this pattern consists of a large number of white spots on a grey green ground, 

 which in the nymotypical form cover the whole hindwing, but which in the form alexandra lUihl from Tur- alexandra. 

 kestan are greatly reduced in number and size. From Ferghana, Tian-shan and Ala-tau, at a considerable 

 height, in June and July. 



C. mongolica Alph. (481i). By far the largest Coenomjmpha. All the wings thickly dusted with mongolica. 

 bluish white, so that the sooty brown ground-colour only appears in the distal margin of the forewing and 

 the apical area of the hindwing. Both wings bear several ocelli on the upperside. Underside lead-grey; 

 a white smear runs from the ajiex of the cell of the hindwing towards the distal margin. — In the Tian-shan, 

 in the Kuldscha district and the neighbouring districts of Mongolia; not rare. 



21. Genus: Triphy^a Z. 



Similar to the preceding in size and shape, the bladder-like inflation at the base of the veins of 

 the forewing is also present. But the antennae are quite short and terminate in a sharply defined heavy 

 knob. The palpi are transformed into brush r like tufts. The anal angle is never produced, but on the 

 contrary quite rounded oif, its outline being but slighly arched, so that the hindwing is longish oval in 

 shape instead of being almost circular. The forewing, moreover, is more elongate, especially in the ?. The 

 colouring in the c/' is a dark sooty brown, in the ?? a dull pearly white: the underside in both sexes is 

 grejish brown, traversed by a network of the pale veins, n forms only are known, which are very similar 

 to each other and are restricted to the Palearctic Region. 



T. phryne Pall. (= tyi-cis Cr.) (48 i) is blackish brown-grey, the wings of the cf having a fine golden phryne.
