Diestman, J. Jr. 1960 Dipsoaurus dorsalis 11 April Pinto Basin, 1750ft., Riverside Co., Calif. at about 10:30a.m. I found one among sparse plants* in sand at east end of dunes. The head was on ground and acted torpid. Cloacal temp. 29.4° C & surface of sand 27.8° C. Easily captured - had a dull yellowish green smear over face and chin. * plants; Malacothrix glabrata Gray Chaenactis macrantha D.C. Eat. This area, close to where the Cratophytus was collected was at the base of the sand dunes with sparse Larea, occasional clumps of grass and deep swales of white sand covered up to 75% with plants - mainly Verbena. The smear effect of this animal could be from eating the yellow flowers of the compositae: † * plants identified by V.C. Kerhammer staff 25 May 60 [† or from eating the Spyngid caterpillars so numerous here - probably the former situation.]
