Dryobates scalaris
Nov. 9 Casita, 40 km. S Nogales, 3300 feet, Sonora.
One collected in oak woodland; one other observed in willows on Nov. 7.
Regard by van Rossem (1945:139) as characteristic riparian and cactus asso-
ciations. The above record may represent a local vagrant, as extensive bottomland timber occurred nearby.
