Eusatina White Rock Ranger Station, 4800 ft, Trinity Co., Calif. June 1, 1946 stream, the crust lying near a group of small Incense Cedars. The individual would probably have been overlooked save for the contrast between the bright yellow forelimbs and the dark earth on which it was lying. The substrate was rather damp, and small black ants were also seen beneath the log. This section of the creek reminded me somewhat of Crystal Creek where E. croceater has been collected. June 2, 1946 Hunted Eusatina from 7-8 a.m. in a canyon about 3/4 mile east of camp. One small specimen (1755-KH3) was taken under a small piece of Douglas Fir bark, lying on an "island" about 60 ft long and 20 ft wide, surrounded by two branches of the main creek— substrate moderately damp. No other animals noted in association with the Eusatina. Vegetation on the "island" included Acer macro- phyllum, Alnus sp., Incense Cedar, and Douglas Fir.
