Types . — Mount Rainier, Washington, various places in 
the natural parks visited at about 5000-6000 feet elevation. In 
all over ninety specimens were secured, including four collected 
by Dr. Aldrich. The flies were observed alighting on stones in 
the sunny pathways and were encountered in Paradise Park, 
Van Trump Park, and Indian Henry Hunting Ground, on Alta 
Vista, Mt. Ararat, and Crystal Mountain. 
A grant from the Elizabeth Thomspon Science fund for 
the purpose of studying the alpine insects of Mount Rainier 
made possible the securing of much of the type material. Para- 
types have been deposited in the National Museum, the Canadian 
National Museum, the Museum of Comparative Zoology of 
Harvard and the Philadelphia Academy of Science.
