The genus Exomalopsis, Spin., was founded in 1851 on a couple of bees from Para, Brazil. Three years later, F. Smith described three additional species, also from Brazil. More recently, species have been described or recorded from Cuba, Jamaica, and Mexico, but none hitherto from the United States. One species, E. pulchella, Cr., has a remarkable range, being found in Cuba (Cresson), Jamaica (Fox), and Lower California (Fox). I myself have taken it in Jamaica.
