Quito, Blair 1973 July 26 Depodome microps 5 ½ mi. N.W. Chagano, White Lava Falls. into the active burrow system from clubs. The single D. microps was taken at this locality. Surprisingly, no evidence of food caches of any sort were found, in contrast to the cone-mound, large food caches found by similar methods at Wolf's Hole. Our investigations were transferred by a broken handle on the G.T. shovel I had brought along. I must buy one with a steel handle when I can. Sept 26 10 mi. N. Wolf's Hole, Mohave Co., Ariz. This area is similar to situation three months ago, except it is even drier. The leaves of the blackbrush are still on the plants, but are a dried brown, with no succulence. There are more frequent hole complexes than in July, and always they occur at mounds topped by barren skeletons of a particular sort of shrub, (see voucha photographs). Quite frequently two K-nats were trapped outside of one burrow complex. These invariably proved to be D. microps and D. merriami.
