Demophile, Fit. 439, 3, 4 (1844). — Smaller than the type, and 
lighter in colour ; the ocellated spots either very small or 
altogether wanting. Judging from the specimens sent to me 
by Dr. Standinger, it very closely resembles the British variety 
Laidion. PI. LXXVII., 4. 
Time of Appeakance. — June and July. 
Habitat. — Lapland and Sweden ; also the Amur (Meiietries, 
Schrencks’ Eeisen, p. 34). 
Obs. — It should be mentioned that Wallengren’s descriptions 
of the varieties occurring in Scandinavia seem to he very close to 
all the forms of the species described above, except the var.

Earlier stages unknown. Small butterflies, having the general 
aspect of the last genus. The wings are rounded, and have the hind 
margins entire ; they are somewhat narrower in the female than in 
the male. The sexes differ remarkably in the colouring and in the 
neuration of the wings : in the male the colour is dark brown, 
whilst that of the female is greenish or greyish white ; the male 
has only the costal and median nervures dilated at the base, in the 
female the submedian has likewise the basal dilatation. The 
discoidal cells are closed. The shafts of the antennae are propor- 
tionately shorter than in Ccenonympha ; the clubs are ovate and 
flattened. The neuration is marked with silvery white, especially 
on the hind wings. All the wings have, beneath, a submarginal 
row of black spots, with silvery centres, and with marginal leaden 
lines, like those in Ccenonympha. 
This genus belongs rightly to the Siberian and Manchurian 
subregions of the Palsearctic fauna. The occurrence of T. Fhryne, 
Pall., in South-East Eussia, at Sarepta, and elsewhere, entitles it 
to stand as a genus of European butterflies, though it is as truly 
Asiatic as Charaxes is African. Only one species is known besides 
that found in Europe, T. Nervosa, Motsch., iiihahiting Japan.
