Three subfamilies, which may for the present be called Centrinae, 

 Anthoporinae, and Eucerinae, are recognized. See Cockerell, T. D. A,

One view is that Schrottky (1905, p. 13; 1909a, p. 160; and 1914, 

 p. 220) is right in saying that, according to strict rules, ^'Centris^' should 

 not be applied to these anthophorid bees.* (See Euglossa.) Schrottky 

 insists on using " Hemisia" for the present genus but " Trachitia" does 

 not seem to have been ruled out. Friese, 1900, used the name Centris 

 and divided the genus into a number of subgenera, but left no typical 

 subgenus. Here, as in certain other genera of bees, would seem to bo a 

 fitting place for name "conservation." 



The following genera or subgenera have been proposed. .

>Thi8 is not clear to me. Schrottky says that no Anthophorid Centrit has "clypeuagibbaK); tibiis 

 posticis incrassatis, compressis, ciliatis"; but these words apply excellently to such a spMies as Cra/rM 

 amerieana Klug. As Fabricius mixed several genera in his Ventrit, later authors were ,at liberty to 

 select a non-euglossid type, such as C. vergtcolor Fabricius. T. D. A. C.
