Abstract

While making a study of the aquatic fauna of Waddell Creek, Rancho del Oso, California, during the summer of 1928, the author collected, along with nymphs of several genera of Ephemerids, nymphs of Ephemerella hecuba Eaton figured by Eaton in his Revisional Monograph, page 133, Plate 40, figures 1-17, and by Needham in the Annals of the Entomological Society of America, volume 20, page 115, and in Bulletin 201, Utah Experiment Station, page 9. Inasmuch as the author was unable to find descriptions of the male and female imagoes in the literature he reared out adults, both male and female, in order to secure material for description. Subimagoes appeared July 11 and the imagoes issued July 12.
