In 1911 I made some fragmentary observations on this hitherto unreported Indian food, which I published the following year in the Journal of the New York Entomological Society (vol.xx, pp. 1-4, plate i). At that time I had obtained only the dried larvæ ready for cooking, and the species could not be determined. My account of the methods of the Indians in collecting and preparing this food was obtained from the clerk of the Mono Lake store, and not written down until two or three days later. No further information came to light for several years, but in 1919 I interested Mr. Roy Headley, of the Forest Service, in the matter again, and he caused some inquiries to be made in the vicinity of Mono Lake. The Indians then stated that the caterpillars occur only every alternate year, and there would be none in 1919. In 1920 Mr. Headley interested Mr. Guy S. Way, of Bishop, Ca1., ranger in the Inyo Forest adjacent to Mono Lake, who took hold of the subject with enthusiasm, wrote several letters on his observations, and sent a liberal shipment of the caterpillars, which settled the identity of the species. From Mr. Way's letters I compile the following account, making a few direct quotations. It will appear at once that my earlier article contains several serious mistakes.
