S. Norton mentions 22 species of ants (whereof 3 are indicated as 
new), contained in 7 genera, and collected in portions of Nevada, Utah, 
Colorado, New Mexico, and Arizona, during 1872-1874. These have 
been examined by Mayr, and 10 species found identical with European 
forms. Chap. vii. of Wheeler’s Rep. Geogr. Explor. W. of 100th Mer. v.
