can be considered as strictly alpine butterflies, though 

 several of the common species of the valleys and forest are 

 found up to, and even above, timber-line. Many of the 

 forest insects seem to be found only where Chtisquca, a 

 bamboo-like grass, is abundant, but some others, such as 

 Argyroj^horm argenfeus, Cosmosatyrus hptoneuroides, and 

 Neomocnas simplex, are found on grassy downs and hills, and 

 never enter the forest so far as I observed. 



In the arrangement of the Hesperiidre I have availed 

 myself of Watson's ' Classification ' of that group (P. Z. S. 

 1893, pp. 3-132). 



I have not studied the generic characters, as it seemed 

 to me that this could not profitably be done without 

 undertaking a study of the allied species from other parts 

 of S. America.

A well-known and very distinct species, the largest of 

 the Chilean Satyridse. I found it common at the Baiios 

 de Cauquenes, where it flies in shady woods and settles 

 on the trunks of trees. It was also common at Temuco 

 and near San Ignacio, but I did not see it in the mountains. 

 The southern form is darker than that found at Valparaiso 

 and Quillota. 



2. Elina vancssoides. 



Elina vancssoides, Blanchard, t. c., p. 28, PL V, figs. 5,6. 



Also a very distinct species which I did not take myself, 

 but which is common in the neighbourhood of Valdivia. 



3. Elina neomyrioides. (Plate XIV, fig. 5 $.) 



$ Satyrus neomyrioides, Blanchard, t. c., p. 33, PL II, 

 figs. 6, 7. 



I doubt whether this species belongs to the same genus 

 as the last. I took it at San Ignacio in January, and at
