50 RHOPALOCERA. 
Hab. Costa Rica (Van Patten }?); Panama, Chiriqui (27bde). 
This is a well-marked species, restricted in its range to Costa Rica and the adjoining 
district of Chiriqui. Its nearest ally is J. celemia, Hew., of Colombia, from which it 
differs in having all the spots on the apical half of the primaries yellow instead of 
white.

Alis flavido-hyalinis, anticis preecipue apud venas fumatis, macula fumata obliqua cellulam transeunte, altera 
ad finem ejus marginibusque anguste nigris, margine interno late nigro, vena mediana anticarum et venis 
posticarum omnibus rufis: subtus ut supra, sed pallidiore, posticarum limbo externo albo punctulato, 
costa fascia elongata rufa utrinque grisea picta. 
@ mari similis, sed maculis anticarum fumatis saturatioribus et posticis interne magis rufescentibus dis- 
tinguenda. 
Hab. Costa Rica (Carmiolt, Van Patten”), Irazu (Rogers); Panama, Chiriqui 
(Zahn). 
Mr. Bates, when describing this species, referred it to the genus or section Dir- 
cenna!; but a further examination of the type specimens and others that have reached 
us shows clearly that the neuration is strictly that of the section in which we now place 
it, and that its resemblance to Dircenna is at most superficial. Though apparently a 
very common species in Costa Rica, we have seen but few specimens from beyond the 
limits of that country. It has no very near ally that we know of; but it comes nearest 
I. lagusa, Hew., of the northern parts of Colombia. 
5. Ithomia patilla. (Jthomia cotytto (lapsu), Tab. V. fig. 6.) 
Ithomia patilla, Hew. Ex. B., Jih. t. ii. f. 2°; Butl. & Druce, P. Z. 8. 1874, p. 3337. 
Ithomia psyche, Bates, Ent. M. Mag. i. p. 34°. 
Alis hyalinis, venis nigris divisis, et marginibus (anticarum apicibus late) nigrescenti circumdatis ; plaga magna 
subquadrata nigra apud anticarum cellule finem spe margine externo cum ramo mediano secundo late nigro 
conjuncto, altera extra eam alba costam fere attingente ; margine posticarum nigro intus sepe ferrugineo : 
subtus ut supra, sed coloribus obscuris multo dilutioribus et rufescentioribus, coste posticarum basi et 
abdomine infra sulphureis; posticarum apicibus albo bipunctulatis ; antennis nigris, prothorace rufo.

One of the commonest species of its family in Central America, being especially 
abundant in Guatemala, where we found it in most of the low-lying forest country on
