MeGACHILE, Latr. 



Cresson, Saunders, and Bingham state that the maxillary 

 palpi are 2-jointed, but Ashmead calls them 4-jointed. We 

 have examined a great many species, including two from 

 Europe, and find in every case three joints to the maxillary 

 palpi ! 



Apis, Linn^. 



The maxillary palpi of Apis are said by authors to be 

 1-jointed, but in the honey-bee we find two joints fairly well 

 differentiated. 



Bom BUS, Fabr. 



Various species examined show 2-jointed maxillary palpi, 

 the basal joint stout, the other slender and cylindrical. 

 B. Kincaidii, Gkll., has the maxillary palpi ,'3-jointed, with 

 two cylindrical joints instead of one.
