ART. X.-NOTICE OF THE BUTTERFLIES COLLECTED BY DR. 

 EDWARD PALMER IN THE ARID REGIONS OF SOUTHERN 

 UTAH AND NORTHERN ARIZONA DURING THE SUMMER 



OF 1877. 



By Samuel H. Scudder. 



Although the collection of Dr. Palmer is not a large one, embracing 

 only forty-one species, it adds considerably to our knowledge of the 

 geographical distribution and variation of the species, and even con- 

 tains several new forms; it seems worthy, therefore, of notice as a 

 whole, and particularly since the special localities visited are oft" the 

 ordinary route of travel. 



The localities mentioned below are the following : * — 



Beaver Mountains, Utah ; the mountains about Beaver, Utah. 



Paragoonah, Utah ; 25 miles west of south of Beaver. 



Bear Valley, Utah ; a valley about 20 miles nearly south of Beaver, 

 surrounded by spurs of the Wahsatch Mountains. 



Pine Mountains, Utah ; "20 miles north of St. George, Utah." 



Mountain Meadows, Utah ; the scene of the noted emigrant massacre, 

 about 30 miles north of St. George. It is an elevated, meadow-like 

 spot, surrounded by mountains. 



St. George, Utah ; at the extreme southern limit of the Territory. 



Mount Trumbull, Utah; "60 miles east of St. George"; a slight ele- 

 vation, in a rough, volcanic, mountainous region. The specimens were 

 collected about a spring at the base. 



Beaver Dam, Arizona; 25 miles west of south of St. George, on Vir- 

 gin Eiver. The most desert-like region visited. Dr. Palmer remarks 

 that in the arid sections of Southern Utah and Northern Arizana, where 

 plants appear only at widely separated localities, the butterflies fly 

 much more swiftly than usual, and are very shy. The easiest place of 

 capture is in the vicinity of springs or pools of rain-water. 



Mokiak Pass, Arizona; "20 miles east of south of St. George"; a 

 pass in mountains between St. George and Juniper Mountains, in a very 

 broken and rough volcanic region. 



Juniper Mountains (or Cedar Eidges), Arizona; a region much like 

 the previous, "40 to 50 miles east of south of St. George", covered 



* Most of these localities may beet be found in the Atlas of Wheeler's Survey for 

 1874 ; but Pine Mountains, Mount Trumbull, Mokiak Pass, and Juniper Mountains do not 

 appear. In these latter cases, I have mentioned the distances given me by Dr. Palmer ; 

 although in the other cases the distances he gave me invariably proved too great.
