COLIAS VIII. 



Taken in abundance by Mr. Mead, in Colorado, in the upper Arkansas Valley 

 and in the vicinity of Twin Lakes, during July 1871. The species seems to re- 

 place C. Alexandra, which is more peculiar to the Platte Valley, although individ- 

 uals of both species are to be found in either district. Foui'-fifths of the females of 

 Scudderii, taken were albinos, while with Alexandra the albinos were exceedingly 

 rare. The latter species was first observed by Mr. Mead on the 15th of June, near 

 the South Park, at an elevation of about 9000 feet, and a few days later it was 

 abundant at Turkey Creek Junction. Many eggs were obtained, deposited on a 

 dwarf species of Lupinus. A young larva was also found. It was three-fourths 

 inch in length, clear green, with a double, yellow-white dorsal stripe and a single 

 lateral stripe of similar color,each stripe enclosing a broken roseate line.
