SMITHSONIAN EXPLORATIONS, I924 



49 



From Oakland, California, the trip was made by automobile to 

 Eureka and on up the coast into Oregon as far as Marshtield. Along 

 this route the extremely dry season made the collecting very poor 

 except in the vicinity of Marshfield, where the climate is compara- 

 tively humid and the collecting was much better. Two days were 

 spent here with very good results. At Corvallis. Oregon, some type 

 material was examined in the collection of the Agricultural College. 



In the vicinity of Spokane, Washington, considerable collecting was 

 done for two or three days, resulting in additions of some value but 

 not of exceptional rarity.

Near Moscow, Idaho, the mountain locally known as Mount Mos- 

 cow was visited on several days and some important material obtained. 

 This mountain is the type locality for a considerable number of new 

 species of insects. At Kendrick. Idaho, the greatest rarity of the 

 trip was discovered, aljout 20 specimens of a fly which was originally 

 described in 1877 from streams in Marin County, California. 



Two days were spent in collecting at Summit, Montana, and at the 

 Glacier National Park railroad station, a region from which very 

 few flies had previously been obtained for the National Museum. 



The illustrations shown (figs. 59, 60) are from photographs taken 

 along the Pacific Coast in southern Oregon, where a very good high- 

 way winds in and out of the forests, frequently following the bluffs 

 along the ocean.
