COLIAS I. 



From Colorado. Mr. James Ridings, who collected in that region in 1864, 

 informs me that he took this species at Empire City, high uji in the mountains 

 near the Snowy Range, in the month of August ; that it was moderately abundant 

 but very wild and difficult to cajiture on account of the unevenness of the ground.
