IDIOTES RUFIFRONS JOUYI (Ridgway) 



Ba»il€utcrus rufifrons joiiyi Ridgway, Proc. U. S. Nat. Mus., vol. 15, 1892, 

 p. 119 (Hacieuda Angostura, San Luis Potosi ; orig. descr. ; type in coll. 

 U. S. Nat. Mus.).— JouY, Proc. U. S. Nat. Mus.. vol. 16, "1893," 1894. p. 

 777, part (same locality; habits). — Ridgw.\t, Bull. U. S. Nat. Mus., No. 

 50, vol. 2, 1902, p. 746 (descr.; range; refs.).— Phillips, Auk, vol. 28, 

 1911, p. 86 (Galindo, Guiaves, Monteluuga, Yerba Burua, Rampahuila, 

 Santa Leonor, and Rio Cruz, Tamaulipas). 



Subspecific characters. — Similar to Idiotes ruffrons caudatus^ but 

 general coloration darker; above darker; yellow of the under parts 

 deeper; posterior under parts less purely white, the shading on the 

 sides and flanks more grayish brown, less buffy. Similar also to 

 Idiotes rujlfrons rufifrons, but upper parts duller, more grayish, less 

 greenish in tone. 



Measurements. — Male: Wing, 51-57 (average, 53); tail, 56-62 

 (59); bill, 9-10 (9.3); tarsus, 19.5-21 (20). Female: Wing, 50-56 

 (53) ; tail, 55-62 (58) ; bill, 9-9.5 (9.3) ; tarsus, 19.5-21 (20.3). 



Range. — Eastern Mexico, from central Tamaulipas to San Luis 

 Potosi, and south to Hidalgo, northern Puebla, and northern Vera 

 Cruz. 



Remarks. — An example in juvenal dress (No. 61,649, Collection 

 Museum of Comparative Zoology, Realito, Tamaulipas, June 14, 

 1909) is dull olive brownish above and dusky buff below, the white 

 superciliaries and dusky postocular spot well marked; the wing- 

 coverts are tipped Avith buffy. 



This is the northeastern race of Idiotes imfifrons., ranging from 

 the State of Tamaulipas southward to Vera Cruz, where it meets the 

 typical form. It is easily told from the latter by its more grayish 

 coloration, but is not so far removed from /. rufifrons caudatus.
