The Halictine Bees of America.— Mr. J. Vachal has published 
the descriptions of a large number of supposed new American bees 
of the genus Halictus, in the Bulletin de la Société Scientifique, 
Historique et Archéologique de la Corréze (France), July-Septem- 
ber, 1904. As this publication is one not usually seen by American 
naturalists, it will be useful to give a list of the species, with the loca- 
lities and some indication of their characters. This information 
follows herewith in tabular form. I have not thought it worth while, 
at present, to give the characters of all the Mexican species; but 
the table clearly separates all those of the United States.
