Type-locality. — Villar, San Luis Potosi, Mexico.

 Tamaulipas and San Luis Potosi : northeast to Victoria, Montelunga,

Like the races of some other species that inhabit the region occu- 

 pied by Dryobates villosus intermedius, this form has a rather limited 

 distribution. Subsequent investigation may, however, somewhat 

 extend its range. 



Six examples have been seen, from the localities that follow: 



San Luis Potosi. — Villar ; mountains near Jesus Maria. 



Tamaulipas. — Miquihuana ; Victoria. 



DRYOBATES VILLOSUS ENISSOMENUS, new subspecies. 



Cliars. subsp. — Similar to Dryobates villosus intermedius, but smaller, 

 and ventral surface darker.
