ADELPHA, 297 
chroa melane probably belongs here, but the female with a white band is doubtless of 
another species. 
A. melanthe was described by Mr. Bates from specimens captured by ourselves in the 
valleys of Central Guatemala. As will be seen above, it has since been taken in many 
other places, not only in Guatemala but elsewhere throughout our region. It inhabits 
thinly-wooded districts, chiefly situated at an elevation of from 2000 to 3000 feet. 
b. Markings of the distal half of the secondaries beneath more or less parallel to 
the outer margin. 
a'. Distal half of the primaries spotted with white.

Hab. Costa Rica (Van Patten1?), Irazu (Rogers); Panama, Volcan de Chiriqui 
(Arcé, Champion), Pefia Blanca (Champion). 
A remarkable species, by reason of its dark wings and the apical portion of the 
primaries being covered with large white spots. 
Besides the type, which is in a damaged condition, we have since received several 
other specimens from Costa Rica; we also have it from the neighbourhood of Chiriqui. 
Curiously enough, of these specimens, seven in number, only two are at all perfect. 
Mr. Butler’s figure represents a female from Costa Rica; that now drawn is a male 
from Chiriqui, but, beyond usual slight difference in the shape of the wings, the sexes 
are alike. 
A. demialba is a mountain species, being found at an elevation of 4000 to 5000 feet. 
It flies high in open spaces in the forest. At Pefia Blanca Mr. Champion saw several 
specimens, but all out of reach. 
b’. Band of the primaries transverse. 
a", Secondaries nearly uniform. 
3. Adelpha sophax. (Tab. XXIX. figg. 1, 2.)

anticis fascia multo pallidiore, maculis apicalibus et alteris cellularibus nigro marginatis notatis ; posticis 
lineis margini externo subparallelibus nigro marginatis, una maculosa submarginali et duabus ad basin 
albis notatis, reliquis plerumque fulvis.
