Karlstein 1955 Buffalo, Arizona July 19 1/2 mi E x SE Niggle, 8200 ft., Alguie Co. Colif. - the shallow dirt still flowing creek. Para musca adults present but no Ibyla found. Extensive seneal among corn lilies, rodent burrow opening, and origin of willow clump. No torde. Chanty Valley, 9700 ft., Alguie Co., Colif. 5:50 8.M. A brief check of this pond and adjacent area revealed not a sign of larvae or transformed toroe. The pond is 2/3rds dried up with maximum depth of water about 16". Weed clumps and crooked around margins. Pond and I turned over logs & stones around pond without re- covering a single torde. There was an abundant host of tadpoles in lute jars, and I would expect metamorphosed torde to be present - or larvae still in the pond. Water beetles (Noticeno) numerous. Water brown-stained slightly but no particular heavy odor of wetlone usually associated with such ponds later in summer. Faith Valley, 9500 ft., Alguie Co., Colif. Pond and I discovered larvae in a couple of seepage streams adjacent to the main creek. Water locked up in places, shallow (to 10-12" max. mum depth). Wot temp. 20.8°C. at 6:45 P.M. Some torde along edges of main 20-25' wide creek; probably washed into creek from seepage pools on meadow surface. Difficult to capture more than a few dozen larvae.
