Herz says of those taken by him on the Vitim, which he 

 describes as rather small, above very dark, I presume they 

 are the same as mine ; I have none from Eastern Asia, 

 but Herz says that three specimens sent by Leder from 

 Mongolia were very light in colour on the upperside.

I only took one in the Tchulishman Valley on July 28th 

 at 5000 feet, but received three or four more from Ongodai. 

 All of these are smaller and paler in colour than usual in 

 Europe, but females from St, Petersburg, which appears 

 to be its most northern range, are also small and pale. 

 They are the same as what Staudinger describes from the 

 Kentei Mountains in Mongolia (cf. Iris, v, p. 330) as var. 

 sihirica. A series from the Ural Mountains, taken by 

 Grum-Grshimailo, were placed under this name in his 

 collection, but I liave some from Modane and Briancon in 

 the Western Alps which I can hardly distinguish from 

 these latter. 



108. A. angarensis, Ersch. 



Two males, both much worn, and a fresh female, were 

 taken by Fletcher on July 28th at about 6000 feet in 

 the Tchulishman Valley, and like those found by Herz 

 on the Vilui and Vitim, average smaller and somewhat 

 darker than those from Kentei and the Amur. The species 

 occurs as far north as the Olenek and Jaua rivers in North- 

 East Siberia, where Czekanowsky seems to have found it 

 abundantly. His collections seem to have been principally 

 made in the district of Verchojansk considerably north of 

 Yakutsk, and when worked out, as I hope they will be 

 shortly, will form a valuable addition to our knowledge of 

 that very remote region. 



109. A.frigga, Thb., var. alpcstris, var. nov. 



This was to me a very unexpected discovery on the high 

 Tchuja Mountains at from 7000 — 8000 feet elevation, where 

 it was common during the first half of July on wet alpine 

 meadows high in the mountains. A bog-loving species 

 like its congener A. freija in Europe and America, it finds 

 here no real peat, and I presume in consequence of this has 

 developed a variety constantly different from all those in 

 my collection both in its paleness and the comparatively 

 slight development of the dark colour at the base of the
