THE TIiVE^ OF THE HIGHER ALPS. 143 



siding among the higher Alpine regions ; it also furnishes us 

 with the greatest number of peculiarly Alpine species. It is 

 true the genera Harpella, Hypercallia, Ndthris, Cltelaria y 

 Parasia, Henicostoma and Phibalocera, do not attain an 

 elevation of 5,000 feet, but Depressaria, Gelechia and 

 Anchinia rise above that level. Of the twenty-three Swiss 

 species of Depressaria, no fewer than seven occur in the 

 higher Alps, and amongst these three peculiar to that region, 

 namely, D. Heydenii and two new species I have discovered, 

 which I name D. alpestris and D. Rhcetica, and which I 

 shortly intend to describe. The four other species, which 

 also occur in the plain are Costosa, Arenella, Liturella and 

 Dadiella. I doubt not that the number of Alpine Depres- 

 saria will eventually be much increased. Likewise the genus 

 Gelechia, of which I know at present eighty-one Swiss 

 species, has twenty-three representatives in the higher Alps, 

 of which five seem peculiar to that elevation, viz. G. prce- 

 clarella, holosericeella, elatella, perpetuella and interalbi- 

 cella. They are found either on rocks or in grass. The 

 remaining eighteen, which are likewise found partly in the 

 plain, are Tripunctella, Maculosella, Galbanella, Lentigi- 

 nosella, Tenebrella, Ericetella, Vicinella [this can hardly 

 be identical with our coast species of that name, H. T. S.], 

 Sequax, Longicornis, Terrella, Distinctella, Artemisiella, 

 Scabidella \_Diffinis, Sta.], Lugubrella, Dimidiella, Coro- 

 nillella, Anthyllidella and Superbella. The genus Anchinia, 

 which only contains four Swiss species, furnishes two peculiar 

 to the higher Alps, Laureolella and Grisescens; and pro- 

 bably Daphnella also ascends above the 5,000 feet line, since 

 Hen* Boll met with it last summer nearly at that elevation 

 in the Engelberg valley. Other species of this family oc- 

 curring in the higher Alps are Cleodora Cytisella, Pleurota 

 semicostella, Sophronia Parenthesella and Humerella.
