in the one place as the other, and if the scenery was not quite so fine, 

 still it was veiy beautiful, having as a background the dome-shaped 

 Titlis towering at the end of the valley. There is here a considerable 

 school and monastery, which owns a great part of the rich pasture 

 hmd of the valley ; and we were struck by the fact that the peasantry 

 of this part of Switzerland seem much more prosperous and well-to- 

 do than those of the southern Cantons. 



In giving a detailed list of my captures, I shall, as usual, follow 

 the order of Staudinger's catalogue. 



Fapilio Machaon, Engstlen Alp. 



Parnassius Apollo, Engelberg ; Mnesnosyne, Engstlen and Tannen Alps. I 

 took this commonly about 6500 feet high. Frey says in his Lepidopteren der 

 Schweiz, p. 3, highest about 5000 feet (Paris feet, equal to say 5328 English feet), 

 and as I took it very near the top of the Tannen Alp, the species evidently flew a 

 good deal higher than the late much esteemed Professor was aware. 



Aporia cratcegi, Engelberg. 



Pieris brassicee and napi, Engelberg, v. bryonicB, Engstlen. I also took a very 

 pretty ? of the usual napi flying among the var. hryoniae. Callidice, Engelberg. 



Anthocharis cardamines , Engelberg and Engstlen. 



CoUas Hyale, Engelberg. 



Polyommatus Hippothoe, Engelberg ; most abundant, also v. Euryhia and v. 

 Stieberi ; this latter may have been unusual for Switzerland, but it is indistinguish- 

 able from some Lapland forms I have. Dorilis, v. subalpina, Engelberg. 



LyccBiia ^gon, Argus, and v. argyrognomon, Engelberg ; Pheretes, Engstlen ; 

 Astrarche, Engelberg and Engstlen, ab. Allous, Engelberg ; Icarus, and ab. Icarinus, 

 Engelberg. I also took at this place (Engelberg) some half dozen specimens of a 

 " Blue " I could not make out, they appeared to be a small variety of " Lycidas," 

 but the spots were smaller and the metallic markings subdued ; however, on sub- 

 mitting them to my friend Dr. Staudinger, he has pronounced them to be a curious 

 form of " Icarus." Eumedon, Engstlen ; Corydon, Hylas, Engelberg ; minima, 

 semiargus, Avion, Engstlen and Engelberg. 



Vanessa urticee, and cardui, Engelberg. 



Melitcea Cynthia, Joch Pass ; Dictynna, Alhalia, Engelberg ; both of these 

 were very abundant indeed. 



Argynnis Euphrosyne, Engelberg and Engstlen ; Pales, Engstlen, a pest 

 literally ; Niobe, and v. Eris, Engelberg. 



Erebia, v. Caxsiope, Engstlen and Engelberg ; Melampus, Maiito, and Tyndarus, 

 all Engstlen, not rare. 



Oeneis Aello, Engstlen and Tannen Alps. 



Pararge Mara, Engelberg. 



EpinepAile Hyperantkus, Engelberg. 



Coenonympha Pamphilus, everywhere. 



Syrichthus Alveus, and y.fritillum,v.caicus and cacali'^e, aW from Engstlen ; 

 serratulce, Engelberg. 



Sisoniades Tages, Engstlen.
