750 ZOOLOGY INSECTS. 



COLIAS MEADII, Edw. 

 Colias Headii, EDW., Butterflies N. A., i. 



C. Meadii was first met with on the Arkansas divide, between Fairplay 

 and California Gulch, Colorado, on the 8th of July. In the same locality, 

 two weeks later, it was especially abundant, and thirty -four specimens were 

 taken. Others were found on Mount Lincoln and Gray's Peaks. It is a 

 strictly alpine insect, being scarcely ever found as low as 10,000 feet above 

 the sea, and having its proper home just at timber line, or a little above. 

 It disappears about the middle of August. In the Arctic regions of Europe 

 and America, a species (C. Hecla) is found, resembling this in color and 

 marking, but differing structurally; and Dr. Staudinger informs me that a 

 very similar species is met with at high elevations in the Himalayahs. 



TERIAS, Swain. 

 tTERIAS NICIPPE, Cramer. 



This, unlike many other southern forms, does not seem to range north- 

 ward in the Rocky Mountains. Specimens were taken by the expedition in 

 Arizona ; and it is recorded from San Diego, Cal. 



DANAIS, (Latr.) Godart. 

 DANAIS AECHIPPUS, Cramer. 



Danais Erlppus (obsolete), KIEBY, Syu. Cat. 

 Danais Plexippns (obsolete), SCUD., Syn. List, 1875. 



Abundant everywhere in the Rocky Mountains below timber line. 



DANAIS BERENICE, Cramer. 

 Danais Gilippus, SMITH- ABB., KIKBY, Cat. 



Taken by the expedition in Southern Utah. In Colorado, this species 

 is rare ; one specimen was seen near Georgetown. It should be looked for 



early in August. 



EUPTOIETA, Doubleday. 



EUPTOIETA CLAUDIA, Cramer. 

 Aryynnis Columlina, MORRIS, Syn. Lept. N. A. 



Brought by the expedition from Arizona and Colorado. The species 

 may be found among the foot-hills of the Rocky Mountains in May, and
