Alis fuliginoso-nigris ; fascia communi lata ocbracea ab apice anticarum ad marginem posticarum internum 

 transeunte, bujus cellulam occupante venis ad apicem divisa et extrorsum valde sinuata ; anticis maculis 

 tribus costalibus ad cellulse finem quoque ocbraceis et lunulis submarginalibus cum ciliis inter venas ejusdem

This Central-American species has long passed under the name of P. cebalus of 

 Boisduval, which was given to a female specimen from an unknown locality. Mons. 

 Charles Oberthiir has kindly lent us the type of F. cebalus, and we find it agrees with an 

 example in our collection, the origin of which is also unknown, and also with one from 

 Dr. Staudinger which came from Santa Catarina in S.E. Brazil. The latter is accom- 

 panied by a male which has a very close general resemblance to P. lycophron ; but the 

 primaries are shorter, the submarginal lunules of the secondaries are wider, and the 

 transverse dark band in consequence narrower. Should, however, this form be found 

 to be inseparable from P. lycophron, it will follow that that species has two forms of 

 female — one like P. jpirithous, as figured by Lucas, the other like P. cebalus. 



From P. lycophron the Central-American form differs in having the apical portion of 

 the common band more distinctly divided by the nervures, each segment being rounded 

 externally, the outer border has, therefore, a very serrated internal edge instead of a 

 comparatively straight one. 



Males vary as to the width of the external border of the primaries and in that of the 

 transverse band of the secondaries, but every gradation is shown in Honduras specimens, 

 so that no specific differences can be based upon this feature. Females also differ 

 considerably, but we have not nearly a sufficient series to say positively whether these 

 differences are in any way localized. Mr. Schaus's female specimen from Coatepec has 

 the innermost of the three submarginal rows of spots on the secondaries distinctly 

 shown, whereas in a Honduras specimen the second row is more strongly developed, 

 but these characters are not sufficiently tangible to separate these forms until at least a 

 larger series is before us.
