Descriptions of New Species of Rhopalocera. 243 
O. montagui similis sed anticis vena mediana fulva, posticis 
medialiter fere omnino fulva ad angulum apicalem vix pallidioribus, 
fascia lata mediana semihyalina haud notata; subtus macula 
exteriori costali alba majore et triangulari maculis submarginalibus 
anticarum albis haud interruptis. Exp. al., 4:0 in. 
The receipt of additional specimens of the true O. 
montagut from the Cauca Valley, in Colombia, shows that 
the Central- American insect referred by us to that species 
is really distinct. ‘This is Dr. Staudinger’s view, and we 
call the species of Central America after him. 
Tithorea monosticta, sp. n. 
T. duenne similis sed posticis fascia transversa integra nigra nulla, 
macula ad angulum apicalem tantum notatis: subtus posticis fascia 
maculosa et macula flavida ad angulum apicalem. Exp. al., 3-95 in. 
Hab. Panama, Chiriqui (Mus. Staudinger). 
A female specimen sent us by Dr. Staudinger differs in 
the above points from 7’. duenna, of Guatemala. It also 
differs from 7’. pinthias of Panama in having a narrower 
dark border round the apical angle of the secondaries 
and a single isolated black spot. 
Phyciodes faustus, sp. n. 
P. ptolyce affinis, alis anticis aliter punctatis, maculis duabus 
medianis (inferiore majore fere rotundata), duabus subapicalibus 
(inferiore parva superiore elongata) fascia mediana posticarum 
integra, lineola submarginali evanescenti. Exp. al., 1°25 in. 
Hab. Panama, Chiriqui (Mus. Staudinger). 
Though compared with P. ptolyca this species has 
only a general resemblance to that insect. The spots 
on the primaries are much fewer in number and 
differently placed, only a small one standing in the 
end of the cell with a larger one below it. ‘I'he wings 
are narrower. 
Phyciodes anomalus, sp. n. 
Alis fusco-nigris, ciliis albo interruptis ; anticis dimidio distali 
punctis albis notato; posticis fascia mediana fulva intra eam 
punctis quibusdam ejusdem coloris et extra eam punctisalbis: subtus
