110 RHOPALOCERA. 
omnino (aut fere) absentibus; subtus area basali anticarum obscuriore et ocellis intra lineam duplicem 
posticarum minoribus. 
Hab. Costa Rica (Van Patten'), Trazu (Rogers). 
Very closely allied to O. puerta of Colombia, and O. simplex of Colombia and Ecuador ; 
it differs, however, chiefly in the submarginal fulvous band being broader on the secon- 
daries, whilst it becomes very narrow towards the costa of the primaries, which it does 
not quite reach. Most of our Costa-Rican specimens are either destitute of or only 
have one or two ill-defined black spots on this band. Beneath also it is very similar to 
O. simplex, but has the inner portion of the primaries blackish brown instead of 
ferruginous. 
The original description was based upon a single specimen in Dr. Van Patten’s 
collection. We have since received several other examples, all agreeing with the type. 
7. Oxeoschistus rogersi. (Tab. IX. figg. 1, 2.) 
Oxeoschistus rogersi, Godm. & Salv. P. Z. 8. 1878, p. 267°. 
Alis fuscis, anticis fascia submarginali venis divisa et parte posteriore maculas disjunctas formante, iis inter 
ramos medianos et radiales superiores fusco notatis, ciliis albescentibus; subtus anticis ut supra, sed 
dilutioribus et maculis minus definitis, posticis fusco-fulvis, serie ocellorum submarginalium maculisque 
variis per alam sparsis argenteo-albis. 
Hab. Costa Rica, Irazu (Rogers!) ; Panama, Chiriqui (Mus. Staudinger). 
The first example of this insect was obtained by our collector Mr. Rogers from 
the mountains of Irazu, in Costa Rica. Soon after the receipt of this specimen 
Dr. Staudinger sent us another to name from the neighbourhood of Chiriqui. These 
are the only ones we have seen at present. It nearest ally is O. phaselis (Hew.), a 
species placed in the genus Pronophila by Hewitson, and subsequently in Dedalma by 
Mr. Butler, but which, in our opinion, ought to be removed to Oxeoschistus. From 
this O. rogersi differs at first sight in the tawny markings on the primaries, those 
wings of O. phaselis being of a uniform brown. On the underside the two are very 
nearly alike. 
8. Oxeoschistus gigas. (Tab. X. figg. 8, 9.) 
Oxeoschistus gigas, Godm. & Salv. P. Z. 8. 1877, p. 62°. 
 alis fuscis, anticis punctis submarginalibus quinque albis, aliis duobus interioribus marginem internum versus, 
posticis marginibus late fulvis, venis fuscis divisis, et puncto nigrescente inter ramos medianos primum et 
secundum notatis; subtus anticis ut supra, sed apice fulvo tincto et maculis indistinctis albidis notatis, 
posticis fulvescentibus externe pallidioribus, ocellis subapicalibus indistinctis serie positis et maculis variis 
albidis per alam notatis. 
Hab. Guatemaua, Aceytuno (Rodriguez), Purula (Champion). 
The type specimen of this fine species was given to Salvin by Don Juan Rodriguez,
