IO4 BANGS A NEW SCOTOTHORUS [ ^V^^ili ' 



Characters. — Similar to true S. verapacis (Scl.) of southern Mexico and 

 northern Central America (type locality, Choctum, Vera Paz), but tail shorter, 

 and coloration considerably darker throughout, especially so on breast and 

 belly, the upper breast being dark reddish olive-green, and the belly and sides 

 dusky grayish olive-green, without the yellowish olive-green edges of the 

 feathers, which give to the belly of true S. verapacis its much paler and more 

 yellowish cast. 



Measurements. — Type, adult male: wing, 89.5 ; tail, 62. 2 ; tarsus, 21.6; 

 exposed culmen, 15.4 mm. Topotype, adult female, no. 7850 : wing, 87. ; tail, 

 61. ; tarsus, 22. ; exposed culmen, 15.6 mm. 



1 Dumicola — that dwells in thickets. 



2 In true 5". vempacis, though the other measurements agree closely with those of the new 

 form, the tail is always longer, averaging about 65 mm.
