Distribution in Colorado.—Western three- fifths of state in suitable habitat (Fig. 102). Comparison.—From M. v. letifera, a sub- species of the Great Plains, M. v. energumenos differs in smaller average cranial and external size, less robust skull, and darker color. Measurements.—External measurements of a male from eastern Rio Blanco County are: 548, 171, 58. Cranial measurements of that individual, of two males from near Crested Butte, Gunnison County, two males from near Colorado Springs, and two males from Co- chetopa Pass, include: condylobasal length, , , , , , , ; zygo- matic breadth, , , , , , , ; postorbital constriction, , , , , , , ; mastoid breadth, , , , , , , ; length of maxillary toothrow, , , , , , , Mean (and extreme) cranial meas- urements of 10 males, followed by those of four females, all from southeastern Larimer County, include: condylobasal length, (), (); zygomatic breadth, (); (); postorbital constriction, (), (); mastoid breadth, (), (); length of maxil- lary toothrow, (), ( ).
