NOTES ON SWISS RHOPALOCERA. I. 229 



10. Melitaea cynthia, Hb. 



SoiTth of Diavolezza Hut even in August if the summer be hot (one 

 worn, 24 viii. 01). Between Bernina Haus and Hotel, top of pa^:s, on 

 flat south-west of road. Took several there 11-18 vii. 01. 



N.B. — There were also many 3i. parthcnie, Brkh., var. varia, M.D., 

 M. aurinia, Rott., var. )iierope, Prunner, Latiorina orbitnltis, Prunner, 

 and Parnasftii(s delius, Esp. 



A/, asieria, Frr., is also reported from there, and from the Heuthal, 

 but I did not see it. 



11. Coenonympha satyrion, Esp., var. unicolor, Wh. 



12. Polyommatus semiargus, Rott., var. montana, Frey, and 



13. Pleheins argyroynomon, Bergst. (argus, L.), var. aegidion, Meiss. 



I found all these on path along west side of Morteratsch glacier. 

 The first 80-150 yds. above the path, just after leaving woods. The 

 attraction seemed to be little bits of black or boggy ground in sheltered 

 corners, as on Alp Grum. 



The second and third I found at corners on path, almost touching 

 moraine, near last dead trees ; some water ran through this tiny 

 hollow. 



N.B. — Further on, below the club hut, I took Erebia gorge, Esp., 

 var. triopes, Spr., and E. alecto, Hb., var. glacialis, Esp. 



14. Erebia fiavofasciata, Heyne. 



I took six on zigzags, 20 metres above the first or lower restaurant, 

 on the Schafberg, 24 vii. 01. I saw none at that point in 1904, but 

 Professor Thieme, of Berlin, and a friend, got 55 from 1-16 vii., on flat 

 path leading south-east from first restaurant towards Languard Alp. 

 The point where they were found has a longer slope of grass (not so 

 steep as most) above path, whilst below it is a rulge descending to just 

 north of Pontresina Old Church. Professor Thieme said that after 

 July 16 was too late iov fiavofasciata. 



N.B. — -The Erebia mnestra, Hb., I took ascending this ridge, 

 28 vii. 04, are a little like E. christi, Ratzer. 



I also took a flacofasciata, 10 viii. 01, on steep slopes east of 

 Tscherva Hut, and another ascending to it on grass slopes above 

 junction of the two glaciers. f 



N.B. — E. epiphron, Enoch, var. cassiope, Fabr., was very abundant 

 on both these slopes. A dark form at that date (10 viii. 01), absent 

 in August, 1904. 



15. Erebia gorge, Esp., var. triopes, Spr. 



High up (with E. glacialis) towards second restaurant, on Schaf- 

 berg, and going towards Piz Languard. However, most abundant at 

 top of Bernina Pass. I took 25 there, 18 vi. 01. 



On Fuorcla Surlej (between Rosegg glacier and St. Moritz. No 

 triopes, but the type with two eyes, 17 viii. 01. 



One of these two specimens has the yellow band, underside hindwing, 

 broken up into spots something like melampus but of irregular shape. It is the 

 specimen to which I referred in the 2nd Obs. on p. 124 in my " Butterflies of 

 Switzerland." — G. W.
