W L Davis 1935 Birch Cr, 2 mi. S E Kaufman, Clark Co., Idaho, June 29. Looked at my gopher sets this a.m. and took 4 ? I. idahoensis from them, all ads. Left Birch Creek about 9:30 a.m. and drove to American Falls via Dubois, Idaho Falls and Pocatello. About 10 mi. W of Winifer, Clark Co., I saw a flock of sage grouse, the two parents and 12 young about half grown, At Small I noticed several Citillus elegans. These, like armatus and oregonus prefer the areas in the vicinity of water and cultivated areas, none was collected because last year I took a few there). I looked for C. mollis along the route but failed to find any save at a locality about 5 mi. E of Terreton, Jefferson Co., here a small colony was located in a sandy clay ridge along the edge of a wheat field. They were extremely wary, I saw two of them and shot at one, but it got down its burrow before I could get it, I dug down about 2 ft. and failed to find it. They looked like the dark phase of the young found at Birch Creek, I hunted here about an hour and gave up because of a dust storm. Dust was so thick that I had difficulty in seeing the road and I was forced to stop twice).
