This species was described fifteen years ago from two much worn and badly dam- 

 aged males, brought in from Yellowstone Lake by Dr. Hayden's Expedition, and 

 until recently I had not known of another example in any collection. Nothing 

 whatever was known of the species except what the dried insects discovered. To 

 call attention to the species I concluded to figure the male only. After the Plate 

 was done, I accidentally learned that Prof. S. A. Peabody, of the University of 

 Illinois, had taken Haydenii in 1887, and he kindly sent me two pretty fresh 

 males, and gave the following account of their capture : " I send you two males 

 Haydenii, I have no females. These were taken in the immediate vicinity of 

 the Falls of the Yellowstone, on the grassy slopes west of the caiion, and at an 

 altitude of about 8,000 feet, or, say, between 7,700 and 8,000. I see that in the 

 Trans. Ent. Soc, V. 19, this species is reported at Yellowstone Lake, which is 

 about 15 miles from the Falls. I did not go there. The altitude of the lake is 

 not materially different from that of the upper fall. I did not see any females. 

 I was at the Falls, Aug. 3d and -ith. On 5th, I passed over Washburn Mountain
