A NEW RACE OF SCOTOTHORUS VER&PACIS 

 FROM CHIRIQUI. 



BY OUTRAM BANGS. 



Salvin and Godman have already called attention, in the 

 Biologia Centrali-Americana, to the darker colors of the form of 

 Scotothor us vercepacis that inhabits southern Central America (Costa 

 Rica and Chiriqui), but they considered the differences between 

 this bird and true 5. vercspacis of southern Mexico and northern 

 Central America, too slight to recognize. Last autumn I got 

 together a considerable series of this bird, and found that the dif- 

 ferences between the two geographic extremes stand out, to my way 

 of thinking, far too clearly and too constantly to permit uniting 

 them under one name. South of Chiriqui, again, in the Varaguan 

 ranges, there appears to be a slightly different form, but the 

 material in the U. S. National Museum is too scant to warrant 

 naming it. Farther south still, in Panama, S. stenorhynchus 

 either takes the place of S. vercepacis or occurs with it. 



The new form may be known as 



Scotothorus veraepacis dumicola x subsp. nov. 



Type, from Divala, Chiriqui, $ adult, no. 7849, coll. of E. A. and O. Bangs, 

 collected Dec. S, 1900, by W. W. Brown, Jr.
