traversing line; submarginal line pale, faintly waved, preceded on submedian 



fold by a dark blotch ; a (lark marginal line ; fringe grey with a whitish basal 

 line. 



Bindwing : with the markings only shown on inner margin, the costal half 

 of wing being w T hitish. 



Underside of forewing dark grey in costal half, white along inner margin ; 

 the pencil of hairs yellowish grey : hindwing white with the markings pale grey ; 

 in the ¥ the whole forewing below is grey. 



Head, thorax, and abdomen pale grey ; dorsum with a dark streak on 

 middle segments, the two basal segments and the anal segment remaining 

 pale grey. 



Expanse of wings : 22 mm. 



3 c?c?i 1 ? from Limbani, Carabaya, Pern, 9500 ft., May 1904, dry season 

 (Ockenden). 



This species differs from the type of the genus T.peregrina Warr. in having the 

 wings narrower and elongate, instead of short and broad ; the hair pencil is yellow, 

 not black. 



In appearance it much resembles Tephroclystia atricollaris Warr. and 

 sticticata AVarr., which both have a dark blotch before submarginal line on the 

 submedian fold. 



A S from Huancabamba, Cerro de Pasco, Pern, 6400 ft. (Bottger), is larger 

 (24 mm.) and much more brightly marked, all the pale tints being lighter ami the 

 dark ones darker. It may stand for the present as ab. lucidior ; like many 

 other species from Huancabamba, it probably represents a well-marked local 

 form. 



Subfamily HETERUSIINAE. 



175. Erateina semilugens spec. nov. 



Closely allied to E. dilectaria Dogn. (Heterusia), but the white streak from 

 base of forewing and the white discal area of hindwing so thickly clothed with 

 slaty black scales as to appear smoky grey, the veins across the latter black ; the 

 inner margin of forewing with no white streak. 



On the underside the basal streak and base of costa of forewing and the 

 discal space of hindwing are silvery white, and the course of the submedian vein 

 of forewing is marked with silvery scales ; the ground-colour in both wings is 

 rich purplish plum-colour. 



On the npperside of hindwing the centre of cell and the whole lower half 

 of the marginal border are clothed with long hairs. 



Expanse of wings : 32 mm. 



1 c? from Cushi, Hininuco, Peru, 1900 m. (Hoffmanns). 



176. Erateina xanthyala spec. nov. 



( 'losely resembling E. comata Druce, but distinguished as follows : ground- 

 colour olive-brown rather thau olive-fuscous ; the hyaline space longer and 

 narrower, yellowish, edged with orange scales, and the veins across it orange, the 

 lowest portion, between veins 3 and 4, produced further hindwards, in the ? 

 reaching halfway to vein 2, and in both sexes produced above vein (i towards costa ; 

 the three pale costal dashes yellowish instead of white. 



Underside with the yellow striae in both wings mixed with deep purple red ;
