A NEW RACE OF SCOTOTHORUOS VERZPACIS 
FROM CHIRIQUI. 
BY OUTRAM BANGS, 
SALVIN AND GopMAN have already called attention, in the 
Biologia Centrali-Americana, to the darker colors of the form of 
Scotothorus verepacis that inhabits southern Central America (Costa 
Rica and Chiriqui), but they considered the differences between 
this bird and true S. verepfaces 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. ver@pacis or occurs with it. 
The new form may be known as 
Scotothorus verzpacis dumicola' subsp. nov. 
Type, from Divala, Chiriqui, J adult, no. 7849, coll. of E. A. and O. Bangs, 
collected Dec. 8, 1900, by W. W. Brown, Jr.
