neger reports a specimen from the Painted Desert at Tan- 

 ner's Gulch. 



In Nevada, it has been taken in Lincoln (Juniper Moun- 

 tains at 6,700 feet near Sheep Spring 15 miles east from 

 Panaca), White Pine (Antelope Springs), Elko (Wells, 

 Elko, Carlin, Deeth), Eureka (Palisade, Cortez Mountains 

 to 7,500 feet). Lander (Austin), Humboldt (Winnemucca 

 at 4,300 feet. Thousand Creek, Quinn River Crossing at 

 4,100 feet, Virgin Valley at 5,000 feet, Amas, mouth of 

 Alder Creek at 5,000 feet, Alder Creek Canyon at 6,000 

 feet, Big Creek Ranch at 4,300 feet. Big Creek Canyon at 

 4,800 to 6,000 feet, Leonard Creek at 5,000 to 6,000 feet), 

 and Ormsby (Carson City), counties. Specimens from 

 Round Mountain, Nye County, are much more like S. g. 

 gracilis, and are best referred to that subspecies. It seems 

 probable that the same may be true of those recorded from 

 8-,000 feet altitude on Mount Magruder, Esmeralda 

 County. 



In Idaho, S. g. graciosus has been secured in Bannock 

 (Pocatello), Bingham (Fort Hall, Blackfoot), Bonneville 

 (Idaho Falls), Cassia (plains near Conant), Jerome (plains 

 between Shoshone and Blue Lakes, Blue Lakes Canyon), 

 Gooding (Bliss, plains between Bliss and the Snake River), 

 Butte (Big Lost River), Lemhi (Lemhi Indian Agency at 

 5,400 feet), Owyhee (plains across river from Glenns 

 Ferry), Ada (Boise), and Washington( Weiser), counties. 



Oregon specimens from Voltage, Harney County, and 

 Warner Lakes and Abert Lake, Lake County, are referred 

 to this subspecies. Those from Summer Lake and Paisley, 

 Lake County, and Umatilla and Pendleton, Umatilla 

 County, may best be referred to S. g. gracilis.
