OF WASHINGTON, VOLUME XI, 1909. 161 



in the Anthophoridse in his Histoire Naturelle (1841). Spin- 

 ola very soon protested against this interpretation of the 

 Fabrician genus, but his voice was not heard. In "Historio 

 Fisco y Politico de Chile," Fauna, vol. vi, p. 167, Spinola 

 gave a full argumentation against Lepeletier's views and 

 showed that the genus Enlcma Lepeletier (englossid) falls 

 into the synonymy of Centris Fabricius, and that Centris 

 Lepeletier must be called Hem isia Klug (anthophor id ). It is pos- 

 sible that Frederick Smith, when he monographed these genera, 

 overlooked the remarks of Spinola, though they were repeated 

 elsewhere. After that it had scarcely been touched till Delia 

 Torre's Catalogue, where it stands as Smith left it. In the 

 last years I already used the names correctly, but in the quota- 

 tions of my papers by Friese, Ducke, Strand, and others 

 the wrong names always reappear. The consequence is that 

 one who is not specialized in these groups quotes correctly 

 Centris among the Euglossidae and describes an anthophorid, 

 etc., as Mr. I. C. Crawford does in "Some Costa Rican Bees," 

 (Trans. Amer. Ent. Soc. xxxn, 1906, p. 157-163). The 

 names must stand as follows : 



Family ANTHOPHORIDyE. 

 Genus HEMISIA Klug, 1807. 



Syn. : Centris, Latreille, Lepeletier, Smith, Friese, Ducke, Fox, Cock- 

 erell, Crawford, etc., nee Fabricius ! 



Family EUGLOSSID^E. 



Genus CENTRIS Fabricius, 1804. 



Syn. : Eulema, Lepeletier, Mocasary, Friese, Ashmead, etc. 

 Syn. : Euglossa, Friese, Ducke, Strand, etc., partim. 



A CORRECTION. 



Basilodes arizona French. 



I gave as a synonym of this species (Proc. Ent. Soc. Wash., 

 xi, 24, 1909) Plusia acantha Druce. It should have been 

 PJusia arianda Druce, with the same reference. A clerical 

 error in copying is responsible for the mistake.
