running up this canon Nisoniades brizo, Eudamus nevada, E. 

 tityrns, Lyccsna pheres and acmon, Pyrgus tessellata and numer- 

 ous beautiful Odonata were found. 



As an illustration of the abundance of the Argynnis, on June 

 2oth, fifty of the two species meadii and nevadentis were taken. 

 The former were found in the valley or lower part of the canon, 

 and nearly all were taken on the blossoms of Achillea millefolium. 

 I soon found the easiest way to take them was to walk up and 

 down the road and quietly capture them while sipping the nectar, 

 for when once started they were not easily caught. 



The A. nevadensis were found farther up the mountain sides, 

 and were most abundant on the sunny slopes, where they were 

 flitting close to the ground under and through the Artemisia. 

 Several unsuccessful chases up the mountain side and one or two 

 falls made me wonder if there was not a better way. I noted that 

 nearly all were working their way up the mountain and seemed 

 to prefer a certain wind-protected patch leading up a narrow but 

 not deep gorge which was so steep one could only ascend it by 

 holding to the shrubs of Artemisia and Quercus gambelii. 



On taking my place near the head of this gorge, I found the 

 question solved, for I had simply to stand and with one quick 

 sweep of the net capture them as they attempted to pass. This 

 method proved so much easier and more satisfactory that I gave 

 up tearing clothes and nets in chasing specimens through the 

 thick brush. It was often interesting to note butterflies flitting 

 from flower to flower up the mountain keeping in the sunlight as 

 the source of light gradually sank to rest behind the hills and 

 then returning to the valleys in same manner the next morning. 



The valleys or cuts between parallel ranges always were the 

 ' best places for collecting, except for such genera as Parnassius 

 and Chionobas. 



Besides species mentioned, Anthocharis ausonides, Nisoniades 

 lucilius, Limenitis weidemeyerii, Melit&a nubigena, Colias ed- 

 wardsii, Pieris occidentalis , D. archippus and Pyrameis carye 

 were taken in Red Butte Canon. 



June 23d I left Salt Lake City for Park City, which is thirty- 

 two miles away, and at an elevation of 7000 feet. Here the most 

 of my collecting was done, an account of which will be given in 

 mv next article.
