560 Nocturnal Lepidoptera 



49. dfspar. In many years extremely abundant, and injurious to fruit 



trees. 



50. salicis. Not rare ; in many years abundant. 



51. v. nigrum has been found near Winterthur (and I have taken it at 



Thun, sitting on my own garden wall). 



52. chrysorrhoe v a. Everywhere very common. In some years the larva 



does great damage to fruit trees. 



53. aurfflua. Also common everywhere. The larva lives on all fruit 



trees ; but not existing in such large societies as the last : it does 

 less mischief. 



O'rgya. 



54. pudibunda. Not rare. 



55. fascelina. Common. 



56. gonostigma. Not common. The larva is found in autumn on 



various trees and shrubs ; but very small : it passes the winter, and 

 arrives at its full growth the following June. 



57. antiqua. More common than the last. 



Pyg^ra. 



58. anastomosis. Rather rare near Berne.

than the last. (Also at Thun.) 



65. populifolia. Has been found a single time near Berne (and since 



frequently at Thun). 



66. quercifolia. Common about Berne, and everywhere as far as stone- 



fruit trees grow. 



67. pini. This moth, whose larva is so notorious for the amazing ra- 



vages it occasions in the pine forests of Germany, is a rarity in all 

 parts of Switzerland, and its destructive effects are unknown here. 

 The larva is occasionally found nean Berne, in February and March, 

 under the turf at the foot of fir trees, where it winters : later, it is 

 not difficult to find, and must be sought for about the tops of the 

 fir trees.

69. potatoria. Very common : the larva is found in damp grass in Ma}\ 



70. lobulina. Very rare. (Then follows an account of rearing some

long notice of the larva.)

the moth is first disclosed late in autumn. I have found a fresh 

 male in the middle of November.
