378 NORTH AMERICAN FAUNA [No. 55 



corded by Miller and Allen from Brownsboro, Corvallis, Philomath, 

 Eugene, Marmot, McKenzie Bridge, Prospect, Tillamook, Reston, 

 and Lookingglass (fig. 95). Others examined in the Jewett collec- 

 tion are from Holly, Linn County; Mercer, Lane County; Remote, 

 Coos County; Gold Beach, Curry County; and still others in the 

 University collection at Eugene from Roseburg, Douglas County; 

 Galice, Josephine County; Grants Pass, and Fish Lake in Jackson 

 County. In the Alex Walker collection specimens have been identi- 

 fied by the Grinnells from Blaine and Tillamook. 



A few individuals from the Willamette Valley are so light that 

 they are referred to calif omicus, but most of the specimens from west 

 of the Cascades in Oregon are of this dark-brown form. They oc- 

 cupy the humid Transition Zone area of the State and are generally 

 abundant in the valley forests, around buildings, and along the 

 watercourses. 



General habits. In the dusk of evening these little brown midgets 

 swarm out of the woods and go skimming over the still surface of 

 streams and ponds, scooping up mouthfuls of water until their thirst 

 is satisfied, then they dodge in and out among the trees or around 

 buildings in such quick and crooked flight that even a good wing 

 shot will get but a lew specimens. Their habits differ from those of 

 calif omicus merely in adaptation to a better forested area as their 

 colors are toned to the deeper shadows. 



Most of the specimens have been collected during the summer, but 

 one was taken at Marmot at the west base of Mount Hood as late as 

 September 12, and Alex Walker collected them at Blaine in Tilla- 

 mook County, on November 24 and 25. Cantwell took another at 

 Philomath on March 12, and Walker another at Blaine on March 26. 

 For the other 4 or 5 months of the year they disappear for their 

 winter quarters, probably in caves or other retreats for hibernation. 



Cantwell shot two at the Rogers Ranch, near Parkdale at the 

 north base of Mount Hood, on the evening of March 27, 1919, after 

 a warm bright day, although 2 feet of snow still covered the ground 

 and no insects were noted in the air.
