Of this species of the characteristically Columbian and Peruvian 

 group Eurytus, two specimens were brought by Mr. H. Tetens of 

 Altona. They were found in great numbers in an Indian village 

 (Macotama) at an altitude of 10,000 feet. The Indians (of the 

 Aruaco stock) used them for food, bringing them from higher up, 

 11-12,000 feet alt.
