280 THE entomologist's record. 



ympha pamphihis. We have already referred to the abundance of 

 dragonflies here, and their lovely appearance in the hot sun. The 

 diptera were not one whit behind. In the hot sun two or three species, 

 with Ancious habits, persecuted us terribly, causing a vile rash over the 

 neck and hands, and from which we were not properly free until our 

 holidays were over. Why are there not more dipterists, and why do 

 those who do exist not want very long series of common species ? " At 

 any rate they might devise some means of exterminating some of these 

 brutes, even if they do not set about it as the lepidopterists exterminated 

 Apatura iris and Melitaea athnlia in Chattenden. 



On the morning of July 28th Ave crossed the Lake of Zurich by a 

 morning boat to WadensAvil and took train for Einsiedeln. This journey 

 was largely to be in the way of spying out the land. EA^erywhere 

 along the rail one saw on either side large stretches of bog-land, 

 similar to that Avorked on the previous day, sometimes more isolated, 

 at others Avith woods and meadoAvs stretching down to its very edges. 

 No doubt the AA'hole of the country is good C. tiphnn country, and 

 produces all the special insects of the bogs. At Einsiedeln Ave "did " 

 the church as recommended, and lunched, and then set ourselves to 

 look round. The immediate neighbourhood of the town appeared to 

 hold nothing more than Dryas paphia, Brenthis awatJiusia, Enodia 

 hyperantlnis, and Erehia ligea, at least AA^e noted nothing more, so we 

 walked through the town and made for some " boggy " ground on 

 the way to Biberbriicke. The ground was very like that Av^e had 

 worked the preceding day, but much more isolated, the AA-oods not 

 coming down to its edge except at one point, and the remainder 

 stretching aAvay to the mountain -pastures beyond. Besides, it was a 

 good 1200ft higher, for Avhereas the Stiifa bog is not more than 

 1700ft. eleA^ation, Einsiedeln is 2900ft. The fauna, therefore, was 

 especially a bog one, and not at all mixed AA^th that from the sur- 

 rounding districts Avith different geological and general characteristics. 

 Most of the true bog insects of the Stafa bog Avere here^ — Coenonijnipha 

 tiphon, Lycaena alcon, Melitaea dictynna, Cramhus sylvellus, C. niar- 

 garitellnH, C. selasellus, etc., Avhilst Enodia hyperontJiiis and E. ianira 

 were both exceedingly common, and Pieris napi generally distributed, 

 but the most striking additions, not noticed the preceding day, Avere 

 Brenthis inu and Lycaena areas, the former in considerable abundance, 

 but worn, the latter more sparingly and the <? s and J s also quite 

 beyond their first beauty. Still it Avas new to me on the A\ung, and I 

 was glad to see its quick arion -like flight, and its sooty $ s were easily 

 recognisable, apart from the deep broAvn underside. Aryynnis aylaia 

 was also frequent as well as Coenonyvipha pawphilns, Adopaea fiava, 

 Aiif/iades sylvaniis and Lcptidia sinapis. The form of C. tijihan AA^as 

 identical Avith that captured at Staefa, but the specimens, although 

 taken some 1200ft. higher Avere more wasted, a suggestion of different local 

 conditions which one did not readily grasp, except that at Einsiedeln 

 the bog forms a Avide open space on Avhich the sun shines all day. 



Off the bog, and on the way to Biberbriicke, lots of interesting places 

 were observed, well worth working no doubt, and, in one place seA'eral 

 Dryas paphia on the Aving formed an interesting picture. Lycaena 

 arioji, Avorn, Erehia aethiops, and Erebia liyea Avere observed on the slopes 

 that ascend from the edge of the bog, with one <? Agriades corydon, 

 the only one seen in the district, the species evidently not yet out, and
