Preliminary examinations of melting points, solubilities, and infrared spectra of the nest-building secretions (cell or nest linings) of Hylaeus cressoni, Nomia melanderi and Anthophora occidentalis were made. The oral secretion of H. cressoni appears to be silk. The dissimilar cell linings of N. melanderi and A. occidentalis contain probably polymerized lipids and do not resemble beeswax. The origin, composition, and possible evolution of nest-building secretions in the Apoidea is reviewed and discussed.
