Friday (July 22rjd) was a splendid cloudless day; tbe 

 thermometer outside our window was at 48° Fahrenbeit 

 when I first looked at it, and never rose above 6'2^ in tbe 

 shade the whole day. I may here mention, that during our 

 whole stay in tbe Engadine we never saw the thermometer 

 above 65° in the shade, though during that veiy time it 

 reached 91° in the south of England. Our first attempt at 

 exploring tbe locality was made up the valley of tbe Fex, on 

 the left-hand side; here we had not progressed far, when, on 

 a rock-face, we found Solenobia cases, which were however 

 all empty, and whilst we were getting these we were accosted 

 by an old gentleman, Herr Knateck, an entomologist from 

 Berlin, settled in the Engadine, who informed us be was in 

 the habit of collecting these Solenobia cases for Professor 

 Frey of Ziirich. This is tbe species which was first eiro- 

 neousiy supr)osed to be Conspurcatella, and is now known 

 as AJpestrellaj Heinemann. As we walked alono- the narrow 

 footpath we noticed from time to time swarms of a pale blue 

 Polyommatus settled in tbe raoister, boggy places ; this I was 

 afterwaids assured by Professor Frey was no other than our 

 own P. Corijdon. 



Amongst the herbage I started a Gelechia trljmnctella (a 

 creature just like our Cinerella, only rather larger and with 

 three black spots), which I captured ; but, with the excep- 

 tion of a Tortrix and one Dipterous insect, this was my only 

 capture that day. We went gradually creeping up tbe valley 

 till we came in view of tbe Fex Glacier and the surrounding 

 peaks, all standing out gloriously against the cloudless sky. 



Of larvsB a ^e\Y of a Depresaria in the flowers of an 

 UmheUifer were secured ; but my most intei'esting find that 

 day was the deserted mines of a Mkropteryx larva in the
