Syrichthus alveus and -S. cacalicB, were both common on dry slopes up to 

 750O feet. 



Hesperia comma (a dark form) and H. lineola, a few, Suvretta Valley. 



Zygana exulans, yery abundant at the higher part of the Cavloccio Valley, also 

 at about 7500 feet near Sils Maria. 



Setina aurita var. rainosa, this Alpine and interesting species (allied to our 

 irrorella) was fairly common on the mountain sides at about 7000 feet. 



Arctia flavia, a connecting link between A. Caja and villica. Mr. Penn found 

 a male and female at rest on the wall of the Hotel d'Angleterre ; the female de- 

 posited eggs freely, and I have now about 70 larvae half grown. Q-erman authors 

 state that the larvffl hibernate two winters, but I should think those I have under 

 the altered conditions will produce moths next summer. 



Gnophos obfascaria var. canaria (similar to Scotch specimens, but larger) dis- 

 turbed from rocks, also at light. G. diluoidaria, one or two, not fine. 



Psodos alpinata, sparingly in the woods between Campfer and St. Moritz. P. 

 quadrifaria, occasionally, up to 7500 feet. 



Fidonia hrunneata (larger than Rannoch specimens) and Acidalia fumata, single 

 specimens of each, Campfer. 



Lolophora sabinata, two, Zmutt Thai, Zermatt. 



Larentia ccBsiata, sparingly, Campfer. 



Melanippe hastata var. suhhastata, Cavloccio Valley, one specimen. 



Cleogene lutearia, the commonest Geometer, flying in the meadows in the 

 afternoon sunshine. 



Anaitia paludata var. imhutata (similar as regards markings to Scotch examples, 

 but larger), Lygris populata, and Euholla mensuraria, single examples of each. 



Diasemia literalis, one or two. (This species I have taken at Stresa, near 

 Lago Maggiore). 



Botys uliginosalis, occasional specimens ; Pempelia carhonariella, Scoparia 

 sudetica, single examples of each. Mimceseoptilus pelidnodactylus, common ; and 

 a few Sciaphila argentana. 



The number of species of butterflies we met with in the Upper 

 Engadine was 58. Mr. Nicholson tells me that he has taken Argynnis 

 Thore near Pontresina, and Professor Frey, in " Die Lepidopteren der 

 Schweiz " mentions 13 others as occurring there, viz., P. MacJiaon, P. 

 Dorilis, L. Euviedon, L. Sehrus, L. Alcon, M. Maturna, var. Wolfens- 

 hergeri, M. Phoehe, M. Dictynna, A. Selene, A. Euphrosyne, E. Evias, 

 S. andromedce, C. Paniscus (2 at Maloja, small form). This makes a 

 total of about 72 butterflies, a very good list, considering the eleva- 

 tion and the limited area, viz., Maloja Pass to Samaden, a distance of 

 15 miles. 



It is doubtful if at any corresponding elevation in the Swiss Alps 

 such a variety could be obtained. Several species of butterflies occur 

 in very limited numbers and as small forms, suggesting that they have 

 difficulty in maintaining an existence at such a high altitude. On the 

 other hand, although the material at hand is very scanty, the moths in 

 several cases are larger than those found in the British Isles.
