186 RHOPALOCERA. 
dg. Alis anticis elongatis, fusco-nigris, margine externo paulo incurvo, area anticarum mediana ad angulum 
analem extensa et venis nigris divisa, fasciisque duabus transversis ultra cellulam, venis quoque divisis, 
_ fulvis; posticis interne fulvis, costa, margine externo et fascia transversa nigro notatis: subtus alis pallidi- 
oribus, fasciis ad anticarum apicem flavidis, posticis lunulis submarginalibus albidis notatis. 
9. Major, anticis minus productis, maculis ad apicem et ad marginem externum ochraceis. 
Hab. Mexico ! 2, Cordova (Rimeli, Hoge), Oaxaca (Menochio) ; GuatTEMALA, forests of 
Northern Vera Paz and Motagua valley (Ff. D. G. & O. S.), Polochic valley (Hague), 
Purula and Teleman (Champion). 
The difference between the sexes of this species led Hewitson to describe them under 
different names, the female as E. phillyra} and the male as E. ezorias*, both specimens 
being from Mexico. We have since obtained from Mexico and Guatemala a large 
series of both sexes, and have no hesitation in placing them as one species. In 
Guatemala and doubtless elsewhere F. phillyra is a forest species, ranging in altitude 
from nearly the sea-level to a height of about 4000 feet. 
As will be seen above, E. phillyra does not appear to be found south of Guatemala. 
In Nicaragua and Costa Rica its place is taken by £. alsina, a species from which it 
may easily be distinguished by the black transverse band of the secondary wings. 
6. Eresia alsina. 
Eresia alsina, Hew. Trans. Ent. Soc. 1869, p. 33'; Ex. Butt., Hresia, t. 8. ff. 62, 63°. 
E, phillyre similis, sed anticis minus falcatis, maculis alarum fulvis paulo dilutioribus, fasciaque posticarum 
nigra transversa absente distinguenda. 
Hab. Nicaracua, Chontales (Belt 12); Costa Rica (Van Patten), Cache (Rogers). 
This was one of Belt’s discoveries in Nicaragua, whence he sent many specimens, 
some of which passed into Hewitson’s collection! and some into ours. We now trace 
it southwards to Costa Rica, where it appears to be not uncommon in the lowland 
forests. As already mentioned, it has a close ally in the more northern EL. phillyra; 
and southwards, in the State of Panama, several allied forms take its place. 
7. Kresia nigripennis. (Tab. XX. figg. 15, 16.)

¢. Alis anticis elongatis falcatis fusco-nigris, maculis indistinctis ultra cellulam serie duplici transversa 
positis alteraque inter ramos medianos primum et secundum flavis; posticis area interna fulva, costa et 
margine externo anguste nigris, maculis duabus indistinctis ad angulum apicalem: subtus ut supra, sed 
maculis flavis multo majoribus, anticis plaga magna fulva ad basin notatis; posticis medialiter albicantibus, 
et lunulis submarginalibus ornatis. 
Q. Mari nonnihil similis, alis anticis minus falcatis et maculis flavis multo magis distinctis, plaga quoque 
indistincta fulva in regione vene mediane. 
Hab. Costa Rica (Carmiol!, Van Patten 234), Cache (Rogers).
