24,9 [November, 



Returning along the same path nearly all the Zygeenida? that I 

 saw were paired, the time would he about the same as adopted by the 

 genus Ino. The llelitcece that I took along this same valley were all 

 of interest, the best being some beautifully fresh maturna-wolfens- 

 bergeri, which occurred not uncommonly among the honeysuckle before 

 the first bridge; a nice pair of fairly typical aurinia also fell to my 

 net, and one or two merope occurred further up the Valley. On the 

 other side just beyond the bridge, parthenie-varia was not uncommon 

 with a few dictynna. Of the Argynnides, pales was as usual common ; 

 amathusia had seen its best days and was not common, I also took it 

 on the Alp Grumm over the Beruina Pass ; just near the delius ground 

 a very dark Argynnis flew rapidly past which I thought might be a 

 prize aberration, so I gave chase, with the result that a fine fresh dark 

 tlwre was added to my list ; niobe, and its form eris, were not rare in 

 the meadows by the Bernina stream at the end of the village, eris being 

 the commoner of the two. 



On another day by the Tschierva Glacier one or two (Eneis aello 

 allowed themselves to be captured, and one Pararge liiera near the 

 Hotel de lioseg. Ccenonympha arcania v. satyrion occurred every- 

 where, whilst one or two between it and darwiniana were also taken. 

 With the Lyccenidce in this valley I was disappointed. Chrysophnnus 

 hippothoe was not common, and one or two virgaurecs were seen but 

 not captured. Lyccena argus was not uncommon ; optilete rare in the 

 Roseg Valley, but very common in the Bernina Valley, and up 

 towards the Morteratsch Glacier ; pheretes I only took around and 

 above the Roseg Hotel, whilst orUtulus occupied much the same 

 ground, but was commoner ; eros was taken, also nearer the village 

 but not commonly ; icarus was decidedly rare, eumedon being fairly 

 common ; I took a few bellargus near the village in the meadows; 

 semiarqus and minima were common nearly everywhere, but avion very 

 rare, only two var. obscura falling to my net. Of the Pieridce, P. 

 napi-bryonice occurred sparingly, and one callidice was stopped in 

 her mad (light. In the Bernina Valley I took one Lyccena donzelii, 

 but along the horizontal path towards the Schafberg it was plentiful 

 on the last day of my visit, being unusually late in its appearance. 



The locality " par excellence " where I should collect in the future 

 would, however, be the Heu Thai, where I only spent three days, none 

 of which were downright real butterfly days, however, the results 

 showed that systematic collecting would be most fruitful. On the 

 best day I had in the valley the sun shone with intense heat during 

 the morning, and at the many rivulets insects assembled on the moist
