The writer has already recorded the cap- ture of this species in Yosemite National Park in January and February'' and Mr. K. S. Hagen has a specimen from Confidence, Tuolumne Co., taken on February 21, 1941. All specimens taken have been found in areas of mountain mizery (Chamaebatia foliolosa), tending to confirm R. Hopping's "^ belief that this plant is its probable host. Canthon simplex var. milltaris Horn ( Scarabaeidae). This species was found very abundant at the entrances to nests of the ground squirrel Citellus beecheyi near Sugar Pine, ^ladera Co., Ma}" 9, 1942. Nearly every active hole had from one to sixteen beetles. The adults were rolling dung from the burrows, a feat which necessitated rolling the balls up at a very sharp angle, sometimes as great as 45 degrees. The dung was usually buried at a distance of from two to six feet from the burrow entrance. On May 19, a herd of cattle moved up the old road near Miami Ranger Station and during the following week the same species was abundant working with cow dung. However, it was noticed that the individuals in this area averaged about mm. longer than those found about the squirrel holes. Possibly this was due to the fact that the larvae reared on squirrel dung had a smaller volume or less satisfactory food to grow on (squirrel droppings are smaller than the average sized ball of cow dung used by this species). ^Linsley, E.
