or varieties. It wears, in fact, the peculiar livery of a species of Ithomia characteristic 

 of the locality in which it is found, in this respect being like the two preceding species. 



** Colhir (1)1(1 whi(]-J(ippots black ; antennal club more abriipllu thickened.

c? ? . Expanse 2". Wings narrow ; shape and position of the black parts same as in 

 N. Inachld, except that the borders are wider. Fore wing : above, with the Ijasal and 

 apical hyaline areas faintly margined with purple, stained in the middle with light yellow, 

 the black posterior border reaching and slightly passing the median nervure and its first 

 branch ; outer margin spotless. Beneath, same as above, except that the marks which

I did not meet Avith this species myself. It Avas taken by M. dc Gand at Nauta, on the 

 Upper Amazons. 



It Avill be useful to enumerate the rest of the described species Avhich I consider to 

 belong to this genus : I inchule a description of a new one in the list.
