258 Messrs. F. Du Cane Godman and O. Salvin on 



ber in the margin of the secondaries. Antennae yellow, the 

 base black. 



? . Exp. 2'9 in. Similar to the male, except that the base 

 of the primaries is dark within the cell, leaving a yellowish 

 spot near the end ; the inner area of the secondaries is fulvous, 

 with two indistinct yellowish spots on either side of the lower 

 radial.

Ohs. This is one of the largest members of the genus, and 

 has a general resemblance in colour to Ithomia xenos (Bates) ; 

 the female closely resembles /. relata, Butl., a common species 

 in Costa Rica, and sent in some numbers in the same col- 

 lection Avith the Napeogenes now described. 



3. Ithomia cesion. 



S • Exp. 2'1 in. Neuration as in/. iUinissa] costa, apical 

 half and inner margin of primaries, and margin of secondaries 

 black ; inner portion of both wings rufous ; five white spots 

 in the dark apex of the primaries, four submarginal and one 

 (the largest) a little beyond the end of the cell. Beneath as 

 above, with the addition of a marginal row of spots on each 

 wing. Antennae long, black.

Ohs. This species belongs to the /. iUinissa group, and is 

 most nearly allied to I. abida^ Hew. It differs in not having 

 a black band across the secondaries. 



4. Ithomia jucunda. 



? . Exp. 1*85 in. Diaphanous ; costa, apex, outer and inner 

 margins of primaries, and a band through the cell following 

 the second median branch, outer margin of secondaries, and 

 all the nervures black ; a small opaque white spot beyond the 

 dark band at the end of the cell of the primaries ; within the 

 dark margin of the secondaries, between the first and second 

 median branches, is a rufous patch. Beneath — the centre of the 

 dark patch at the end of the cell of the primaries, the costa, 

 and the greater part of the margin of the secondaries rufous ; 

 base of the costa of the secondaries yellow. In neuration this 

 species most resembles /. terra ; the discoidal nervures of the 

 secondaries are almost in a straight line, and carry no recurrent 

 nervule; the junction of the lower radial with the discoidals 

 falls in the diaphanous part of the wing.
