 2 Black bars on upper parts smaller and narrower and more or less 



obscure; spots on underparts smaller and less numerous 



Chrysoptilus punctigula ujhelyii.

 B Underparts barred. 



I Chin and throat uniform black; larger belly more or less banded 



C. artricollis atricottis.

*Chrysoptilus melanolaemus melanolasmus (Malherbe)* BLACK- 

 THROATED WOODPECKER. 



Picus melanolcemus MALHERBE, Mon. Picidas, II, 1862, p. 188; IV, 1862, pi. 89, 

 figs. 7-8 (Bolivia). 



Chrysoptilus melanolcemus GRANT, Ibis, 1911, p. 321 (Los Ynglases, Ajo, 50 

 miles south of Buenos Aires, Argentina, and Goya, near Parana River, north- 

 eastern Argentina). 



Chrysoptilus cristatus SCLATER and HUDSON, Argentine Orn., 1889, p. 21; HAR. 

 GITT, Cat. Bds. Brit. Mus., XVIII, 1890, p. 1 12, part (Bolivia and Argentina). 



Range: Bolivia and northern, northwestern and northeastern 

 Argentina; 11 Uruguay; Chile? 



2: Argentina (Tapia, Tucuman) 2. 



See remarks by Hargitt, Cat. Bds. Brit. Mus., XVIII, 1890, p. 112, footnote, 

 regarding the type of melanolcemus Malherbe. 



NOTE: Considerable uncertainty exists regarding records for cristatus and 

 melanolcemus (largely due to confusion of the names by several writers) ; several such 

 records I have intentionally omitted. 



b A good series of specimens from Bolivia and northeastern Argentina should be 

 compared. I am strongly inclined to believe that birds from northeastern Argentina 

 (Buenos Aires), etc., and Uruguay, should be separated subspecifically from those 

 from Bolivia and northern and western Argentina. Seven specimens from Conchitas, 

 Buenos Aires, differ from two from Province de Tucuman and two from Mendoza in 

 having a relatively shorter wing and bill and the dark coloration of the back, wings, 

 and tail distinctly more brownish black (less deep black). The under surfaces of the 

 outer tail feathers have a middle stripe of yellowish olive bordering the shaft on both 

 webs, and the under surface of the outer webs of the first and second outer tail 

 feathers are barred, while in birds from Tucuman and Mendoza the yellowish olive 

 stripe is absent and the under surface of the second outer feather is immaculate deep 

 black, except at the extreme tip. Should these differences prove constant I propose 

 to name the eastern bird Chrysoptilus melanolcemus perplexus. Type from Conchitas 

 Buenos Aires. Wing, 145; bill 29.
