166 Lord Walsingham's revision of the 



Felderia doeri, n. s. (PL VIII., figs. 20, 20 a, 20 6). 

 Labial palpi overarcliing the thorax, and reaching beyond its 

 posterior margin. Antenna subochreous, strongly bipectinate, the 

 pectinations fringed on both sides with slender hairs. Head, 

 thorax, and palpi mottled cinereous and greyish brown. Fore 

 wings cinereous, blotched and mottled with greyish brown 

 throughout ; the costa obscurely spotted with fuscous from base to 

 apex ; a conspicuous brownish fuscous spot at the end of the cell, 

 a more conspicuous spot of the same colour beyond the middle of 

 the fold, preceded by a smaller one also on the fold. Under side 

 with a slight ochreous tinge about apex and apical margin. Hind 

 icings cinereous-brown. Abdomen greyish brown ; anal tuft paler; 

 the lateral claspers of peculiar form, being thickened at the base, 

 attenuated and abruptly arched upwards in the middle, with the 

 dilated spoon- shaped apex depressed and terminated in several 

 small tooth-like processes, evidently adapted for firm grasping ; 

 the uncus is double, curved, but with the points parallel and closely 

 approximate. 



Received from He it H. Doer ; Petropolis, near Rio 

 Janeiro, Brazil. Five males in my collection. 



Felderia maculata, n. s. (PI. VIII., fig. 21). 

 Palpi overarching the thorax and reaching to its posterior edge. 

 Antenna; subochreous, strongly bipectinate, the pectinations 

 fringed with slender hairs. Head, palpi, and thorax dull umber. 

 Fore wings dull umber, with a few brownish ochreous scales at the 

 base of the fold and costal margin ; a conspicuous whitish ochreous 

 patch occupies the apical portion of the wing, reaching to the 

 middle of the apical margin ; a projecting point of umber scales 

 encroaches upon it from the cosia at its inner edge; a few whitish 

 ochreous scales are scattered throughout the umber fringes. Hind 

 wings umber-brown, slightly paler than the fore wings. Abdomen 

 the same ; the lateral claspers are dilated from their base upwards, 

 but of equal width beyond it ; they are rounded at the apex, and 

 indented along their inner edge ; the uncus is abruptly angulated 

 above, the two points being very long and reaching straight down- 

 wards to beyond the ends of the claspers ; they are closely approxi- 

 mate and parallel, except at their extreme points, which are 

 slightly divergent. Exp. al. 35 mm. 



Hab, Two males received from Hear II. Doer from 

 Petropolis, near Rio Janeiro, Brazil.
