November, 1908.] 24] 



We return again dissatisfied ; but with our faces homewards, the 

 sun greets us once more, and as w r e make our way across the Campfer 

 meadows towards the " Bad," having resolved to take the lower road, 

 ahout 4.30 to 5 p.m., Ino statices v. heydenreichii could be boxed by 

 the dozen, nearly all in copula, and even more commonly geryon v. 

 chrysoccphala, also in the same position ; evidently this is the time 

 of copulation, for another morning and earlier in the afternoon they 

 were feeding, dying, and ovipositing ; I also took one Zygcena v. manni 

 near this spot. 



The time had come, however, to move on to Pontresina, hoping 

 for better results. Our first afternoon's walk was up the hill on the 

 right side of the stream as we go up it, but beyond one Vanessa io 

 taken at rest below a vast overhanging rock, very little was seen ; 

 however, an occasional Gnophos mendicaria, two glaucinaria, and one 

 or two Psodos quadrifaria, enlivened the walk. 



Many were the days spent in the Roseg Valley, so they will there- 

 fore be better considered altogether. Parnassius delius was common 

 in both sexes iu a stony spot surrounded by the rushing Roseg streams, 

 where the ¥ could be seen ovipositing on the saxifrage that was in 

 abundance among the stones ; all the specimens I took were very pale 

 indeed, quite different to those on the Bernina Road by the Heu 

 Thai, and also in the Heu Thai itself ; here they were much suffused, 

 but I fear the marshy laud on the Bernina Road will be no more, for 

 the electric railway over the Pass goes through the very ground they 

 love, and it will no doubt be drained by this time ; with delius, Colias 

 phicomone was dying abundantly, and Erebia pharte often strayed over 

 the stones from the grassy side of the stream ; here also it was that 

 I found just emerged from the pupa a male If. rubi within an inch of 

 the water, its cocoon I could find nowhere, and I wondered whether 

 a heavy thunderstorm that raised the height of the streams con- 

 siderably had not placed it under water. 



Up to this point in the Valley Erebia euryale was common ; tyn- 

 darus was by no means common here, but on the mountain on the way 

 to the Piz Languard both it and melampus occurred, whilst further 

 along the Roseg towards the Tschierva Glacier lappona was in good 

 condition there, I also took a few specimens of mnestra ; Zygcena 

 exulans-vanadis swarmed, both sexes flying briskly in the hot sun or 

 feeding on the flower heads ; Zygcena v. manni also occurred on the 

 same ground. Plusia hochenwarthii was often stopped in its rapid 

 flight and found resting places in my boxes, whilst one P. ain did 

 likewise.
