536 MR. H. W. BATES ON THE LEPIDOPTERA 
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. 
** Collar and wing-lappets black ; antenna! club more abruptly thickened. 
10. Napeogenes pheranthes, n. sp. 
» 
<* £ . Expanse 2". Wings narrow ; shape and position of the hlack parts same as in 
N. Inachia, except that the horders are wider. Fore wing : above, with the basal 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 
are black above are of a fulvous colour, and the apical margin has three white spots. 
Hind icing : above, with the discal hyaline area faintly margined with purple, yellow 
in the middle ; the hind border wide and orange-coloured, margined with black, as in N. 
Inachia. Beneath, the same, except that the costa has a long fulvous stripe, and the 
outer margin a series of five white spots. 
Body black : collar and wing-lappets spotted with white ; a central line on the meso- 
thorax also white. Antennae black : club yellow. 
Taken at Eonte Boa. Bare. 
11. Napeogenes crocodes, n. sp. 
d . Expanse 2". Colours above and beneath almost precisely as in Napeogenes Bharo, 
Hewits. (Exot. Butt. Ithomia, figs. 143, 144). The hyaline areas are rather paler straw- 
colour, the wings much narrower. Antennae black ; club yellow. 
Body black ; collar and wing-lappets spotted with white ; a central line on the meso- 
thorax also white. 
Taken at Tabatinga, in company with N. Bharo. It is evidently a local modification 
of 2i. pheranthes, modified in colours to mimic JV. Bharo. 
12. Napeogenes Duessa, Hewitson. 
Ithomia Duessa, Hewits. Exot. Butt. Ithomia, fig. 137. 
I did not meet with this species myself. It was taken by M. de Gand at ]S T auta, on the 
Upper Amazons. 
It will be useful to enumerate the rest of the described species which I consider to 
belong to this genus : I include a description of a new one in the list.

This is the mimetic analogue of Ithomia Celemia, Hewits. (1. c. Ithomia, fig. 22), found
