Still more productivB tlian Lej Nair was another smaller lake at a 

 somewhat lower level near Campf'er. S. arctica and alpestris were not 

 taken there, although they may quite well occur, but 8. metallica, 

 L. duhia, ^. juncea, Agrion puella and Tiastulatum, and E cyrithiijcrum 

 (the last two being also found at Lej Nair) were all more or less 

 abundant. In the woods Sijmpetrum meridional e and S. striolatum 

 were frequently seen ; and one day near Silvaplana I believe I saw 

 P. depressum. The only species which should have been found and 

 was not, was ^. coerulea, which was taken by Mr. McLachlan at the 

 Staatzer See. It must surely be much rarer in the Alps than in the 

 boreal parts of Europe. 



At Silvaplana our dragon-fly hunting ended. We went on to 

 Maloja and Chiavenna on the 25th, and after visiting Como proceeded 

 over the Spliigen to Thusis, thence home by way of Zurich and Basel. 

 Excepting a Cordulid noticed flying about the pier at Varenna and a 

 few examples of Sympetrum in the Val Bregaglia and elsewhere, no 

 more dragon-flies were seen. 



The total number of species observed on our journey was 45. 

 The first rush of dragon-fly life was over before we reached Switzer- 

 land. Brachytron pratense had absolutely disappeared, the Libelhilas 

 and Leucorrhinias were practically over, while the time of Sympetrum 

 and Lestes had not yet fully come. One or two additional species 

 might have been obtained by visiting special localities, but we were 

 well content with the results which could scarcely have been achieved 

 if we had not had the good fortune to be under such experienced and 

 painstaking guidance. The following is a complete list of the species 

 seen : —
