SCADA.—AERIA. 15 
Alis flavis subhyalinis, marginibus (punctis albis notatis) et fascia obliqua cellule terminum transeunte nigris ; 
subtus velut supra sed paulo pallidior. 
Hab. Costa Rica (Van Patten*), Irazu (Rogers); Panama?, Calobre (Arcé), Lion 
Hill (d‘Leannan'). 
Mr. Bates in his original description compares this species with the Brazilian 
S. gazoria (Godt.), and with S. zemira (Hew.), of Ecuador ; but its nearest ally seems 
to us to be S. zibia (Hew.), of Ecuador, from which it differs in the greater extent and 
brighter colour of the yellow of both wings. Its range seems restricted to the isthmus 
of Central America between Costa Rica and Panama. Colombian and Venezuelan 
examples of this form, though certainly very similar to S. xanthina, approach more 
nearly to the Ecuadorean S. zibia. The original types of this species were sent us by 
the late James M‘Leannan from his station on the Panama Railway, Lion Hill; but we 
have figured a male from Calobre in better condition.

Ithomia, section 3, Aeria, Doubleday, Gen. Diurn. Lep. i. p. 126. 
Terminal joint of palpi small; costal and subcostal nervures of secondaries of male 
wider apart than in Scada; lower discocellular directed backwards. 
This small section has similar front legs to Scada, and therein differs from all 
other [thomiew except Sats. There are about four or five species of this form, which 
seem subject to certain local variations. They are found from Brazil to Guatemala.

A close ally of A. ewrimedia (Cr. Pap. Ex. t. 126. figs. C, D), but differing from that 
species in the brighter colour of the citron marks of the wings, in the narrower 
median citron band of the secondaries, and in the absence beneath of the rufous marks 
in the black submarginal borders of both wings. It is a common species on the 
Isthmus of Panama, and thence northwards as far as Nicaragua. In Guatemala its 
place is taken by A. pacifica, which differs from it in having rufous marks in the black
