A LIST OF GEOMETRID^E FROM BAKER COUNTY, OREGON
by James H. Baker
This list of Geometridas is the result of some twenty years of collecting in Baker County, Oregon. The exact location is the site of our family cabin, located about eleven miles northwest of Baker, in the foothills of the Elkhorn Range, at an elevation of 3800 feet. The Elkhorn Range is a part of the Blue Mountains of the region.
Vegetation in the general vicinity is dominated by White Fir and Pon-derosa Pine. Deciduous trees include willow, aspen, poplar and vine maple. Among the shrubs are currant, rose, sagebrush, snowberry bush, and elderberry. There is a good ground cover of ferns and assorted grasses. The area is ungrazed and is typical transition life zone.
Grateful acknowledgment is extended to those who have helped in the determinations. Dr. J. H. McDunnough was very helpful in the determination of the Eupithecia, and identifications of Dysstroma were made by D. C. Ferguson. And to Dr. Frederick H. Rindge of the American Museum of Natural History I am especially indebted for the correct determination of the various other genera. The sequence is that of the 1938 McDunnough Check List. Where two dates are given, these are my earliest and latest records.
