Nests of Centris heithausi are described from an earthen floor of a workshop in Guanacaste Prov., Costa Rica. Nests usually consisted of a short burrow occupied by 2 or 3 urn-shaped cells. Some nests consisted of a short burrow that opened to a chamber with several cells, and in one case 2 side burrows, built into the walls. Cells were provisioned with a clear tasteless oil and the pollen of Cochlospermum vitifolium. Males of C. heithausi established territories (presumably for mating) in flowering crowns of the following trees and lianas: Gliricidia sepium, Piscidia carthagenensis, Cassia emarginata, C. grandis, Securidaca sylvestris, and Coch/ospermum vitifolium. Males rarely appeared to scent mark vegetation around their territories. The source of the presumed scent is a gland described from the hindleg. Chemicals isolated from the gland include the ester tetradecenyl acetate and eleven hydrocarbons. The relationship of C. heithausi to other Centris spp. is discussed.
