produced a few uMschna graiuUs. By tliiy time the woodland paths 

 were quite gloomy, and stealing along them JS. cyanea was taken. 

 An unusual capture on the way home was C. csnea flying along the 

 road. 



On the following morning we reluctantly bade adieu to our good 

 friends at Kheinau and proceeded to Chur, whence we drove to 

 Lenzerheide, a health resort, situated between C'hurwalden and 

 Tiefencastel, at an elevation of about 4800 feet. Here we remained 

 until July 18th. It looked an excellent locality for Neuroptera, 

 possessing a fine lake, the Heidsee, and an abundance of running 

 waters. The weather which had been hot and cloudless in the low 

 country, changed when we reached the Alps, and for a day or two 

 thunder storms and heavy rain prevailed to a degree that was rather 

 depressing. In the fitful gleams of sunshine we saw few dragon- 

 flies ; odd examples of Somatochlora, a ? S. aJpestris being taken, 

 Orthetrum coerulescens, Lihellula quadrimaculata, Leucorrliinia dubia, 

 and Enallagma cyathigerum. These gave very little promise of what 

 was in store for us. Finally, after a terrific storm, the morning 

 broke cool and cloudless, giving promise of a fine day. The forenoon 

 will long be remembered. A stretch of boggy land on the side of the 

 stream, just after it leaves the lake, was found to be alive with 

 Somatochlora, and here during the next few days beautiful series of 

 S. alpestris and S. arctica were caught. On the quiet portion of a 

 lateral streamlet and at the lake a few S. metallica were found, but 

 here this species was scarcer than the other two. jSSschna juncea 

 proved to be common also, and Gordulegaster annuJatus was seen 

 during the last two days, but it was still rare, and I failed to get more 

 than one ^. 



Our next move was over the Julier Pass to ISilvaplana. We had 

 DO difliculty in making out, from the excellent maps with which 

 Dr. Kis had provided us, where the most likely localities were to be 

 found. Crossing to the other side of the Silvaplana See and going 

 through the woods in the direction of Campfer, we soon found the 

 Lej Nair, and here and on the marshes surrounding it we discovered 

 once more the haunts of the lovely alpine Cordulines. Somatochlora 

 metallica was particularly abundant and an easy capture as it hawked 

 round the margins of the lake. An interesting form of Galopteryx 

 sflenden'A occurred rarely here, very similar to that which I found at 

 Digne, and much closer to the southern form than the one occurring 

 about Ziirich. M. juncea was exceedingly common, and was noticed 

 even at the Hannen See (7000 feet), the only dragon-fly seen there.
