Rio Javary, 1st December, 1874. 



Somewhat similar to one or two Indian species which I 

 have seen in Mr. Moore's collection ; it is the first appa- 

 rently typical Miresa that I have seen from the New 

 World. 



Neomiresa, n. gen.* 



Nyssia, Walker (nee Guenee). 



Walker wrongly applied this name in full consciousness 

 of the fact ; actually stating that it Avas preoccupied at 

 the foot of the page (cf. Lep. Het. v. p. 1132). 



133. Neomiresa rufa, n. sp. 



$ . Wings above rufous-brown ; primaries with the in- 

 terno-median and discal areas dark reddish-brown ; a black 

 spot in the cell ; outer and inner margins and veins pale and 

 sericeous ; a < -shaped marking below the cell and behind 

 it two dots (together almost making a 3), and a series of 

 discal dots beyond the cell, metallic silver ; secondaries with 

 a pale sericeous outer margin ; under surface paler than 

 above, with paler shining veins and margins ; primaries 

 with the disc opaline between the veins ; body sericeous :

The smallest species known to me. 



134. Neomiresa argentata. 



Nyssia argentata, Walker, Lep. Het. v. p. 1134 

 (1855). 

 Juruapuca, Rio Jurua, 11th NoveTiiber, 1874. 

 The single examj^le taken by Mt*. Trail is smaller and 

 altogether brighter in its colouring than Walker's type.
