302 THE ENTOMOLOGIST. 



and, flying about in the long grass, Coenonympha Salyrion 

 and P. Eurydice. As we ascended, Erebia Cassiope, Euryale 

 and Mnestra appeared ; at one spot Lycajna Acis was taken. 

 Now and then, and gelling more numerous as we ascended, 

 specimens of two of" the mountain "clouded yellows," Colias 

 Palaeno and Phiconione, flew across the paih. These two 

 species, together with Pieris Callidice, Argynnis Pales, and a 

 jirofusion of Erebia -Tyndarus, were to be found at the 

 highest parts of the pass; for although patches of snow lay 

 about near the road, the day was a hot one, with a bright sun. 

 Psodos trepidaria also occurred here abundantly, settling 

 generally on the roads, together with a few of E. Cassiope, 

 which, however, was not so abundant at this elevation as it 

 was slightly lower down. I have found this Erebia and 

 pj. Tyndarus at a greater elevation than any of the other 

 Erebia? : a considerably elevated position seems to be neces- 

 sary for their existence, as also for E. Mnestra. E. Ligea and 

 Euryale seem to prefer situations comparatively but little 

 elevated from the valleys, disappearing altogether above the 

 height of 3000 feet or so; while E, Medea and Goante may 

 sometimes be taken in the valleys, or but a very short distance 

 up the mountain sides. The commonest of all the Erebia was 

 E. Medea. 



The next day, on the journey from the Rhone Glacier to 

 Meyringen, over the Grimsel, we saw very few insects, chiefly 

 on account of the bad weather, and partly owing also to the 

 fact that the grandeur of the scenery claimed a large share of 

 one's attention. We saw a few E. Cassiope, Colias Pahdeno, 

 and Psodos trepidaria, on the higlier ground ; lower down, 

 P. Rapae, Arge Galataea, and P. Cardui. Though we met 

 only with these, 1 should imagine that this pass, so varied in 

 all its natural Jealures, was particularly rich in insects. 



In the evening we reached Meyringen, after a hard day's 

 walking; and spent the next day, and part of the 18th, at 

 this village. The weather was intensely hot, — too hot, in 

 fact, for active work in the way of collecting insects. Lepi- 

 doptera were very abundant, especially in the valley : here I 

 met with unusual numbers of E. Janira, P. Megaera, P. Bras- 

 sicae, Rapae and Napi; also with P. Machaon, C. Edusa and 

 Hyale, V. Anliopa, Urtica3 and lo, P. Cardui, A. Paphia and 

 Lathonia, L. iEgon, Corydon, Tiresias and Alexis, P. Dorilis, 

 P. Linea and Sylvanus. In the slightly elevated woods,
