Plant Community Relationships. A total of 1,385 specimens was collected. The greatest numbers occurred in the Gravia-Lycium com- munity, with three-eights of this nimiber in Salsola. In Coleogyne and .\rtemisia they were onh' one-fiftieth as abundant as in disturbed Cravia-Lycium. A few specimens were taken from Larrea-Franseria, and communities. None was found in the Pin- von-Juniper or Lycium. Seasonal Activity. This species was active from .March to December, with the peak of abundance in March, April and .May. Tlie num- bers collected dropped off rapidly in June and reniained low from July to October. In Novem- ber only four specimens were c-ollcc-ted and in December only one. In disturbed Crayia-L\'cium, C;rayia-L\ciinTi, Salsola, Coleog\ne and Larrea- Franseria communities activity began in March. In Salsola activity was recorded until Dec-em- ber whereas the disturbed Gravia-Lycium had activity until November and Gravia-L\cium only until Ma\'. .Activity in Goleog\'ne stop[X'd in April for
