Charles Papp of the CES Entomology Dept. identified them. They are members of the family Tenebrionidae. The name is Eusattus productus LeConte. His only specimen came from Sonora, Mexico.

This morning at 0630, Frank Aubrey & I left UCR for collecting station III. We arrived at the site at 0740. The wind was blowing between 13 & 23 mph., with gusts to 29 mph. out of the northwest. However, we gathered our soil samples and began looking for lizards at 0820. Nevertheless, none were caught until 0850. The wind gradually eased a bit, but never stopped blowing. By the time we quit looking at 1145, we had captured the following: Uma ignota: 19 (6 ad. ?, 6 ad. ?, 4 imm. ?, 3 imm. ?) Dipsosaurus dorsalis: 2 (2 half-grown; sex ?) We caught a Callisaurus draconoides along the old highway on our way home, bringing our total catch for the morning to 22 animals.
