Rhinura gen. nov. 



Fore/riiti/: very liroad, triiiugular ; costa strongl}- archeil, liut slightly inflexetl 

 before middle ; liindmargin with a blunt angulation at vein 4, concave above to 

 vein ?, which is also slightly toothed below apex. 



Ilimlwinq : with apex rounded, slight teeth at veins 6 and 4, and a short 

 curved tail at vein 3, thence to anal angle twice excavated. 



Palpi porrect, the second segment long, rongh-haired, third segment short, 

 pointed, and smooth ; tongue and frenulum present ; antennae simple. 



Nenration as in I'salioc/es. 



Type : Rhinura varicyuta Warr. (Plemi/riopsis). 



It is necessary to remove this species from Plemi/iiopnis, with which it has 

 no true affinity. 



Rhodomena gen. nov. 



1 find that several species of Ilijihiomena from South America difler from 

 typical members of that genus in the shape of the palpi. In these the second 

 segment is much elongated, curved above, and quite narrow whore it rises from the 

 first segment, the third segment short, decumbent ; the palpi are porrect, laterally 

 flattened, and rough-haired above and below ; externally, in all cases examined, 

 they are metallic dark green in colour. Moreover, in all the species which 

 j)0ssess palpi of this structure, the metathoracic tuft is of the same metallic 

 lustre. The two species praelatata and lyraemundata described by me both 

 belong to this genus, and I propose praelatata as type. Both were originally 

 described from $ i : 1 have since seen ? ? of both ; that of praelatata 

 agrees with the $ entirely ; the single ? of prannnmhxtn seen diifers from 

 the S in having the space beyond the cell and beyond the middle of the sub- 

 median interval suffused with reddish ; this may not, however, prove a sexual 

 diflFcrence. 



154. Rhodomena lichenosa spec. nov. 



Foreu'ing : olive-green: the lines and bauds purple-brown; extreme base 

 dark; basal line thick, projecting on median vein, followed by a similarly shaped 

 band with darker edges, almost interrupted in the cell ; median line indented 

 in cell and thickened into a blotch on submedian fold ; postmedian line indented 

 beyond cell, angled outwards above and below ; submarginal band united to a 

 blotch from a{)ex, almost interrupted at middle and enlarged above ; a marginal 

 line of brown triangles at the end of veins ; fringe brt)wn ; the central space 

 is white, sprinkled with green scales, and more or less tinged with pink. 



liindwinij : dull grey ; fringes darker. 



Underside dull greenish grey, with an under-tint of pinkish ; costa of forewing 

 marked with six dark greenish blotches, the intervals cream-colour, all becoming 

 dilfused as they descend from the costa. 



Face cream-colour with two dark spots above ; palpi dark green ; vertex, 

 thorax, and patagia dark and light green ; abdomen cinereous, the segments 

 of dorsum marked with dark and light green ; metathoracic tuft dark green. 



The single ? has the green and pink tinges deeper ; the hindwing darker 

 grey. 



Expanse of wings ; cj, 32 mm. ; V, 35 mm.
