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 Guauaxuato, 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.

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.

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

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

 tained by Dr. Staudinger.
