One, female, September 14, on the Rio Florida. This example was not large, and the 

 under surface, especially of secondaries, was suffused with reddish-yellow to an ab 

 normal extent ; but I have seen an example from Gnanaxuato, Mexico, partaking of 

 this same peculiarity.

On August 8 three examples were taken in the Rio Navajo Valley, near the upper 

 part of the river, and a number observed during that day s march. These are larger 

 than any I had previously seen from Colorado, in this assimilating to those found in 

 Arizona.

Examples taken July 27 at head of the Tule Valley, and on 31, Pagosa Springs and 

 other points not directly stated. 



This species is also found in the Old World in Switzerland, and the mountainous parts 

 of Hungary, Italy, and France ; it presents but little variation regardless of locality.

July 15, taken at head of South Fork of Rio Chama ; July 27, head of Tule Valley ; 

 August 1, waterfall on San Juan River; August 23, Rio Piedro, near the bridge on 

 upper road. 



There is no doubt but that this is a form of E. Medusa Fab., in which view I am sus 

 tained by Dr. Staudinger.
