THE TINEJ3 OF THE HIGHER ALPS. 141 



several weeks in the splendid Engadine, in the Orisons, and 

 lived at Samaden, more than 5,000 feet above the level of 

 the sea. We explored the neighbourhood, mountain and 

 valley. Herr Senator von Heyden had previously been 

 twice for the same purpose to the neighbouring St. Moritz. 

 His captures we have since carefully studied at Frankfort. 

 Some species we obtained last year from Herr Pfaffenzeller, 

 at Samaden. Numerous shorter excursions in the nearer 

 Alps have likewise furnished us with some species. 



I. Among the first family of the Tineina, the Exapat'idce, 

 I have hitherto found no species in the Alps of either of the 

 genera Exapate, Dasystoma and Chimabacche. Neither 

 does Semioscopis appear to be represented. This seems 

 extraordinary ; for should even the want of many broad- 

 leaved trees explain the non-occurrence of the Exapatidcz , 

 yet one would expect that the Alpine alder (Abius viridis) 

 and the Alpine willows would furnish food for some of the 

 species. 



II. On the contrary, in the higher regions of the Alps, 

 the family Tine'idce (from which I exclude the genus Mi- 

 cropteryx) is rather well represented. The mode of life of 

 larva? of the Tineidce, on low plants, on lichens, grass, and 

 in wood, must especially fit them for an abode at a consider- 

 able elevation, just as many of the species occur in the 

 high latitudes of Europe, whereof we have proof in the works 

 of Zetterstedt, Tengstrom and Madame Lienig. We have 

 obtained Talcrporia pseudobombycella, a Solenobia, Xysma- 

 todoma melanella, Incurvaria Masculella, Capitella and 

 Rupella. There also occurs there one Adela, namely, Fibu- 

 Mia, and likewise Nemophora Pihdella. No species of 

 the genus Ochsenheimeria has hitherto been taken. The
